Polyurethane composite panels
Polyurethane composite panel is also called PU sandwich panel.
The polyurethane composite panel with polyurethane as core material consists of upper and lower layers of color steel plates plus intermediate foamed polyurethane. It adopts the world’s advanced six-component online automatic operation mixing and pouring technology, which can complete the mixing process of social batching center or factory at one time online, and can be adjusted online at will according to the temperature, thus producing distinctive high-strength, energy-saving and green building panels.
Because of its good fireproof and moistureproof performance, it is also commonly used as the sealing core material of other materials composite board. Polyurethane sealing composite board adopts high-quality color coated steel plate as the surface material, continuous rock wool, glass wool as the core material, high-density rigid foam polyurethane as the enterprise mouth filling, after high-pressure foam curing, automatic dense cloth cotton and by the ultra-long double overlap belt control molding composite, compared with the traditional hanging cotton maintenance materials, fireproof, thermal insulation effect Compared with the traditional wool maintenance material, it has better fireproofing and heat preservation effect, longer lasting performance, convenient installation and elegant appearance. It is the leading steel building maintenance material.
It is generally used as the outer roof panel of buildings, which has good heat insulation, thermal insulation and sound insulation effects, and polyurethane is non-combustible and meets fire safety. The joint action of upper and lower panels plus polyurethane has high strength and stiffness, and the lower panel is smooth and flat with clear lines, increasing the beauty and flatness of the interior. It is easy to install, short construction period and beautiful.
This sandwich panel has light weight, beautiful and good anti-corrosion performance, and can be processed directly. It provides a new type of raw material to the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry, etc. It plays a good effect of steel instead of wood, efficient construction, energy saving, pollution prevention, etc.
As a new type of building energy-saving insulation material, polyurethane composite board has been widely used in different countries. Its use plays an important role in promoting the continuous innovation of building materials, and as the modern requirements for the construction industry become higher and higher, especially for the use of materials in the house is very demanding, so the choice of polyurethane composite board is a general trend.
Application scope
Polyurethane composite panels as building energy-saving insulation materials have been commonly used in Europe, the United States, Japan and other developed countries, with a penetration rate of 80%, but less than 10% in China. Polyurethane sandwich panel as an excellent energy-saving insulation material, its excellent heat insulation, fireproofing and heat preservation performance can also provide efficient solutions to solve China’s energy consumption crisis.
Polyurethane sandwich panels are widely used in large industrial plants, cold storage, garages, mobile homes, pavilions, exhibition halls, stadiums, shopping centers, airports, power plants, villas, hospitals, ground floors and high-rise office buildings, etc. Due to the excellent thermal insulation properties are mainly used in roofs and walls of industrial and civil buildings.
Thermal insulation performance
Grade A polyurethane composite board has excellent thermal insulation performance
The 5cm thick composite board is equivalent to the insulation effect of 1m thick concrete, which has excellent heat preservation performance.
Polyurethane rigid foam is a new type of polymer material with the excellent performance of small weight capacity, low thermal conductivity, high closed porosity and corrosion resistance
Airtightness
Advantages of roofing panels
Polyurethane roofing panels are connected by concealed nails, and the panels are lapped closely.
Unique waterproof groove design effectively prevents rainwater infiltration and avoids cold bridge phenomenon.
The 40mm crest height greatly improves the bearing capacity of the roof panel. While ensuring the heat preservation effect of the building, it effectively reduces the construction cost of customers, and the roof slope can be as low as 3%.
Wall panel advantages
Concealed nail connection, no exposed screws on the surface, the building wall is beautiful and smooth.
Very high flexural bearing capacity, superior mechanical properties of the wall, reducing the dependence on auxiliary steel structures.
Excellent thermal insulation performance, reducing the cost of air conditioning installations in the building interior.
A variety of appearance effects, beautiful wall surface.
Technical advantages
Highly efficient thermal insulation
A-grade composite board is the low thermal conductivity (≤0.022) among organic insulation materials, and the 5-cm-thick A-grade polyurethane composite board is equivalent to the thermal insulation effect of 1 m-thick concrete. A-grade polyurethane composite board is the ideal insulation product to achieve the target of 75% energy saving in China’s buildings.
Super flame retardant
A-grade composite board can not be burned through by 1000℃ flame for 30 minutes.
Durable weather resistance
A-grade composite board has been tested for weather resistance for more than 6 months, and the performance is stable and can last with the building.
Good dimensional stability
The compressive strength of A-grade polyurethane composite panel reaches more than 200kp, and the panel has good temperature change resistance and does not deform.
Low carbon and environmental protection
A-grade polyurethane composite panel adopts bio-based raw materials, fluorine-free foam, and does not adopt harmful substances prohibited or restricted by the state, which is green and environmental friendly.
