Six new roofing waterproof materials

Rigid foamed polyurethane

Rigid foamed polyurethane is used in roofing works to provide both waterproof and thermal insulation. Among all building insulation materials, foamed polyurethane is one of the lowest thermal conductivity materials. Its performance characteristic is that the sealing ratio of the internal structure is ≥92%, the foamed surface layer forms a smooth film, the closed cell ratio is close to 100%, and it has high water repellency; the pressure resistance at a density of 40kg/m3 Strength >1.5mpa; has a certain elasticity, elongation is 10%; good adhesion to metal, concrete, masonry, wood, glass. Its use characteristics are: rigid foamed polyurethane adopts two methods of on-site spray foaming and composite precasting. Jet foaming uses two components to join together during spraying and reacts immediately to form a foamed polyurethane. This method can be used in large quantities for in-situ foaming. In the case of unsuitable foaming in the field, a prefabricated composite board can be used, and the gap between the boards can be filled with a foaming gun, and the effect is also good.

Scope of application: Rigid foamed polyurethane can be used in a variety of roofing projects. The base layer used is mainly concrete cast-in-place, precast concrete slab and cement mortar screed. There is a single in-situ foaming polyurethane, which is used as both a waterproof layer and a heat-insulating layer; some are used as one of the waterproof layers, and at the same time, they are an insulating layer, which is composited with waterproofing membranes or waterproof coatings; also useful as waterproof coatings, waterproofing membranes, Three kinds of foamed polyurethane materials are combined to form a waterproof and thermal insulation layer. The slope roofing method mainly foams on the base concrete and then hangs the tiles on it. The fundamental solution to the problem of insulation in flat roofs is to use structurally sloped roof structures, especially cast-in-place concrete roofing, in the design of roofing structures using rigid foamed polyurethane.

Biaxially stretched polyvinyl chloride sheet

Biaxial stretching means that at a certain high temperature, the polyvinyl chloride sheet is 100% stretched in two directions perpendicular to each other, so that the molecular chains of the polyvinyl chloride sheet are reordered, so that the cohesive force of the molecules is large. Increased, significantly improved the physical and mechanical properties of the board. Before stretching, the anti-UV layer and the polyvinyl chloride layer are co-extruded and then subjected to a biaxial stretching process, which ensures that the ultraviolet shielding layer is uniformly and densely covered on the surface layer of the sheet, and is completely integrated with the polyvinyl chloride layer. . This process overcomes the weakness of the strength and durability of ordinary polyvinyl chloride sheets and becomes a high-grade high-quality material. Its performance characteristics are: strong impact resistance, more than twice the ordinary polyvinyl chloride sheet; anti-ice force test, stone diameter 30mm, not broken; 50kg heavy sandbag test, can withstand height 120cm (plate thickness 1.2mm); It can be used at low temperature of -30 °C; the light transmission performance can reach 90% (the original 80% can be maintained after 10 years); the impact resistance is >900kj/m2 after 10 years; the impact resistance after bending is >500kj/m2 It has strong corrosion resistance, is not affected by the atmosphere, rain, snow and chemical agents, and will not be swallowed by biological species; it has good flame retardant performance and is a difficult material for building materials.

Scope of application: Biaxially stretched PVC sheets are divided into two types, colored and colorless, which can be used for waterproofing of large public buildings, industrial plants, stadiums, flower planting and aquaculture greenhouses, shelters, gazebos, etc. Indoor screens, soundproof curtain walls, safety hoods, wall of houses, guardrails, partition walls, site safety barriers and tunnels.

Rigid foamed polyurethane is used in roofing works to provide both waterproof and thermal insulation. Among all building insulation materials, foamed polyurethane is one of the materials with the lowest thermal conductivity.

Co-extruded sandwich foamed polyvinyl chloride sheet

The production and use of co-extruded sandwich foamed polyvinyl chloride slabs has just begun in China. Due to high production efficiency, reliable quality, reasonable price and beautiful appearance, it has sprung up in roofing waterproof materials.

Its shape is like a small wave asbestos tile, the length can be determined according to needs; the other is similar to the shape of the European tile. After the width is determined, the length can be determined according to needs, and the color can be various. Its performance characteristics are: light texture, good toughness, strong impact resistance, uniform foam, smooth surface, can be planed, nailed, sawed, sticky, thermoplastic, can be used for secondary processing by molding equipment; weathering, corrosion resistance , UV resistant, waterproof, insulated, flame retardant, heat preservation, heat insulation, easy to install and construct.

Scope of use: It can be used for slope roofs of public buildings, residential buildings, factory buildings, etc. It can also be used for interior and exterior decoration and partitioning of buildings. The thickness of the tile is 2~20mm (mainly produced is 3~5mm), the width is 880-1040mm, and the length can be made according to requirements. The color of the tile can be formulated in the raw material or painted after extrusion.

Color profiled steel plate

The color profiled steel plate is pressed and formed at the factory or at the construction site. The steel plate used is a strip pre-coated product, which is produced by chemical pretreatment, initial coating and fine coating on a high-speed continuous unit. The quality of the painted metal is more uniform and stable than that of a single-piece spray or brushed metal surface. The color coated steel sheet has excellent decorative property, moldability, corrosion resistance, strong coating adhesion, and can maintain bright color for a long time. Its performance characteristics are: light weight; long service life, the use period is 15~30 years; high construction efficiency, compared with the traditional structure, can shorten the construction period by 20%; the color selection range is wide; the section is reasonable, the steel plate strength can be fully utilized, Good strength and rigidity; good heat resistance, continuous heating in an oven at 120 °C for 96h, no significant change in gloss and color of the coating; good low temperature resistance, bending and impact resistance of the coating after standing at -54 °C for 24 h There is no obvious change; the service life of the steel plate can be 15 to 30 years without scratching the coating.

Scope of application: It is suitable for building roof slabs and wall slabs, especially for roofs and retaining structures of large-span factory buildings, warehouses and mobile homes.

Polycarbonate board

Polycarbonate sheet is a good architectural decoration and roof waterproofing material. It has been used in many large public buildings and public facilities in China in recent years. Its performance characteristics are that the thickness is generally 1mm~8mm, and the size can be determined according to needs. Polycarbonate sheets are divided into single and double sheets. Light weight, high strength, impact resistance, not easy to break, colorful, waterproof, heat insulation, light transmission, sound insulation, flame retardant, anti-UV, anti-infrared, can be bent without heating, easy to operate, civilized construction, clean and tidy on site Features.

Scope of use: It can be used for interior and exterior decoration of buildings such as roofs, shelter roofs, walls, partitions, curtain walls, etc., as well as greenhouses, public telephone booths, billboards, light boxes and display arrangements.

Thermal insulation waterproof roof panel

The thermal insulation waterproof roof panel is a self-waterproof roof panel made in a prefabricated factory, and the surface can be sprayed with color paint. The plate consists of steel frame ribs and waterproof layer, thermal insulation layer and fiber or steel wire.
