Selection of plastic for decorative panels
At present, China's plastic sheet mainly includes extruded PVC rigid sheet, PVC foam board, PC board, PMMA board, aluminum-plastic composite exterior wall board, glass steel board, and PS board and ABS board for civil products.
Commonly used plastic sheet materials are: PVC, PMMA, PC, ABS, PF, EP, MF, PI, PS, PE and PP, of which the latter three are mainly used for foamed sheets.
PVC is a commonly used raw material for plastic sheets. It can produce soft, hard, transparent and opaque sheets. It can be produced by extrusion or calendering.
PMMA sheet is the most transparent material in plastics, and has good hardness, electrical insulation, mechanical strength, adhesion and secondary processing. It is widely used in construction, mainly used as lighting partition and roof flat roof. Wait.
PS has three kinds of dense board, low foaming board and high foaming board, among which foaming board is most commonly used. The PS dense board can be used to replace various patterns by replacing the embossing rolls, and is widely used for ceilings, partitions, and patterned glass plates for interior decoration. PS low-foaming board is often used as a wood-like material for furniture and decorative materials, such as various decorative strips because of its light weight, non-deformability, sawability, planability, etc. PS high foam board is often used in building insulation walls. board.
PE and PP sheets are often used as low foaming products. For example, PE low foaming sheets can be used as decorative materials such as ceilings, and PP low foaming sheets are mainly used as wood-like materials.
PF and EP are mainly used as laminates and the like. ABS is mainly used as a vacuum blister product.
MF is the abbreviation of melamine-formaldehyde resin. It is a thermosetting resin formed by polycondensation of tripolychloramine and formaldehyde. It began industrial production in the 1930s. Its synthesis principle is similar to that of UF, that is, the addition reaction of melamine and formaldehyde is first carried out, mainly producing trimethylol and trimethylolmelamine, and then methylolamine is further polycondensed to form a resin.
Since the MF has a trinitrogen heterocyclic structure and a reactive group capable of undergoing a crosslinking reaction, the heat-resistant, moisture-resistant and mechanical strength of the crosslinked cured product is superior to that of the urea-formaldehyde resin.
MF is used as the substrate, and a curing agent, a filler, a coloring agent, a lubricant, etc. can be added to obtain MF plastic, which is referred to as melamine plastic. It not only has the similar advantages of UF plastic, but also has higher heat resistance, moisture resistance, low water absorption, etc. It can be used for a long time under boiling water conditions, and sometimes the temperature can reach 150-200 °C. MF plastic products have high surface hardness, are resistant to pollution, and can be easily removed like ceramics. Therefore, they are widely used and are often used as decorative laminates in construction.
In addition to molding plastics, MF can also be used for injection molding, laminating plastic products and adhesives.
