Polyurethane composite board
Polyurethane composite panel is also called PU sandwich panel.
The composite panel with polyurethane as the core material is composed of upper and lower color steel plates and foamed polyurethane in the middle. It adopts the world’s most advanced six-component online automatic operation mixing and pouring technology, which can complete the proportioning and mixing process of social batching centers or factories online in one go. It can be adjusted online at will according to the temperature, thereby producing distinctive high-strength, energy-saving, green and environmentally friendly building panels.
Because of its good fireproof and moisture-proof properties, it is also often used as the edge-sealing core material of composite panels made of other materials. Polyurethane edge-sealed composite panels use high-quality color-coated steel plates as surface materials, continuous rock wool and glass wool as core materials, and high-density hard composite panels. Foamed polyurethane is filled with grooves and grooves. After high-pressure foaming and solidification, it is automatically densely packed with cotton and controlled by ultra-long double covering tapes. Compared with traditional hanging cotton maintenance materials, it has better fire prevention and thermal insulation effects and longer-lasting performance. , easy to install and elegant in appearance. is a leader in steel building maintenance materials.
Generally used as roof outer panels of buildings, the panels have good thermal insulation, heat insulation, and sound insulation effects, and polyurethane does not support combustion and complies with fire safety. The combined effect of the upper and lower boards plus polyurethane has high strength and rigidity. The lower board is smooth and flat with clear lines, which increases the aesthetics and smoothness of the interior. It is easy to install, has a short construction period and is beautiful. It is a new type of building material.
This sandwich panel is lightweight, beautiful and has good anti-corrosion properties, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, etc., playing a role in steel It has good effects such as wood replacement, efficient construction, energy saving, and prevention of pollution.
As a new type of building energy-saving insulation material, polyurethane composite panels have been widely used in different countries. Its use plays an important role in promoting the continuous innovation of building materials. With the modern requirements for the construction industry The demand is getting higher and higher, especially for the use of materials in the house. Therefore, choosing polyurethane composite panels is a general trend.
Application scope
As a building energy-saving insulation material, polyurethane composite panels have been widely used in developed countries such as Europe, the United States, and Japan, with a penetration rate of 80%. However, their application in my country is less than 10%. As an excellent energy-saving insulation material, polyurethane sandwich panels can provide efficient solutions to China’s energy consumption crisis due to their excellent thermal insulation, fire prevention and thermal insulation properties.
Polyurethane sandwich panels are widely used in large industrial plants, cold storages, garages, mobile homes, exhibition halls, exhibition halls, gymnasiums, shopping malls, airports, power plants, villas, hospitals, strata and high-rise office buildings, etc. Due to their excellent thermal insulation The performance is mainly used in roofs and walls of industrial and civil buildings.
Thermal insulation performance
Class A polyurethane composite panels have excellent thermal insulation properties
A 5cm thick composite board is equivalent to the thermal insulation effect of 1m thick concrete and has excellent thermal insulation performance.
Polyurethane rigid foam is a new type of polymer material with excellent properties of small bulk density, low thermal conductivity, high closed cell rate and corrosion resistance
Air tightness
Advantages of roof panels
Polyurethane roof panels are connected with hidden nails, and the panels overlap tightly.
The unique waterproof gutter design effectively prevents rainwater penetration and avoids cold bridge phenomenon.
The crest height of 40mm greatly improves the load-bearing capacity of roof panels. While ensuring the thermal insulation effect of the building, it can effectively reduce the customer’s construction costs, and the roof slope can be as low as 3%.
Advantages of wall panels
Concealed nail connection, no exposed screws on the surface, and the building wall is beautiful and smooth.
Extremely high flexural bearing capacity and superior wall mechanical properties reduce reliance on auxiliary steel structures.
Excellent thermal insulation performance, reducing the cost of indoor air conditioning equipment in buildings.
Various appearance effects, beautiful walls.
Technical advantages
Efficient thermal insulation
Class A composite panels have a low thermal conductivity (≤0.022) among organic insulation materials. A 5cm thick Class A polyurethane composite panel is equivalent to the thermal insulation effect of 1m thick concrete. Class A polyurethane composite panels are an ideal insulation product to achieve the 75% goal of building energy saving in my country
Super flame retardant
Grade A composite panels cannot be burned through a 1000°C flame for 30 minutes.
Durable weather resistance
Grade A composite panels have undergone weather resistance testing for more than 6 months. Their performance is stable and can last as long as the building.
Good dimensional stability
The compressive strength of Class A polyurethane composite panels reaches more than 200kp, and the panels have good temperature resistance and will not deform.
Low carbon and environmentally friendly
Class A polyurethane composite panels use bio-based raw materials, fluorine-free foaming, and do not use harmful substances banned or restricted by the state, and are green and environmentally friendly.
