Solid surface material (artificial stone), scientific name polymer mineral filled composite material, is a patented technology invented by DuPont Company in the 1970s. The main ingredients are methyl methacrylate (MMA), filler powder, natural pigment and other raw materials. Its products are non-toxic, non-radioactive, non-sticky, pollution-free, antibacterial, mildew-proof, impact-resistant, easy to maintain, seamless splicing and arbitrary modeling.
2. Classification of artificial stones
According to the different process and raw material formula, artificial stones can be divided into the following three categories:
Acrylic acid: The main raw materials are methyl methacrylate, ultrafine aluminum hydroxide and pigment. Pure acrylic artificial stone has strong anti-aging performance, and the aging cycle can generally reach 15 years, which can be used for outdoor decoration. Because of its high requirements on the technology and equipment of manufacturers and the higher cost of raw materials than other products, the market price has been high. Such as DuPont products Colijn? )。
Polyester: At present, most artificial stone products on the market belong to this category. The main raw materials are unsaturated resin, aluminum hydroxide and pigment. Such as DuPont Monterey series (Monterey? )。
AP (DuPont AP resin): It is a new type of resin developed by DuPont. Dupont AP resin is the main material. The physical and chemical properties of the product are more stable, the hardness, thermal bending, flexibility and impact resistance are more prominent, and the color permeability and stability are significantly improved. Such as DuPont product star Polly (simple? )。
Another is to use quartz sand instead of aluminum powder, and its resin and additives are also different, such as diatomite.
Note: Acrylic acid (or unsaturated resin), aluminum hydroxide and pigment are only the main components of artificial stone. For example, the mineral titanium dioxide is needed to make white artificial stone.

The chemical name of acrylic is polymethyl methacrylate, abbreviated as PMMA. It is an environmentally friendly material, which is widely used in home decoration. In addition to artificial stones, there are bathtubs in the bathroom, washbasins in the bathroom and toilets in the bathroom. Acrylic is also the main material of dentures and contact lenses, which shows that it is non-toxic and environmentally friendly and has superior performance. The advantages of using it as a countertop are anti-aging, good hardness, good air permeability, non-toxic and tasteless, and not easy to break; The aging period is long, generally reaching 15 years. In terms of processability, the sheet with high Jacques content is flaky when cut, and the polyester sheet is white powder when cut.
aluminum hydroxide
Aluminum hydroxide (AL(OH)3), also known as natural aluminum powder, also accounts for a large proportion in the three components. Good artificial stone, its content accounts for 30%. The advantages of using it to make countertops are: good brightness, smooth surface, good pollution resistance, wear resistance, impact resistance, aging resistance and high structural strength. The flame retardant of artificial stone depends on aluminum hydroxide containing three water molecules, which does not produce toxic and corrosive gases during pyrolysis; When pyrolyzing, it absorbs heat and releases water vapor, which has flame retardant and self-extinguishing properties.
If the content of aluminum hydroxide reaches 30% and the mesh number (the unit to measure the particle size) reaches 2000 meshes, then such artificial stone is of high quality. The larger the mesh number, the finer the particles or powder. If it is integrated into an internal substance, the structure between molecules will be more compact, and there will be basically no pores and pores, so oil or some dirty impurities and dirt will not easily penetrate into it. On the surface without pores and pores, stubborn stains such as smoke stains and oil stains can also be removed. On the surface without pores and pores, microorganisms such as molds and sclerotia can't survive, so it can be seen that mesh number also plays an extremely important role in environmental protection and hygiene.
The mesh number of ultrafine aluminum hydroxide used in DuPont artificial stone is 2000 mesh. )
At present, many people think that the brighter the surface, the higher the price. In fact, this idea and viewpoint are not completely correct. Nowadays, in the artificial stone industry circle, there are usually two ways to treat bright desktop. One is to coat the surface with a layer of "glazed" raw materials; The other is to brush a layer of specially treated resin on the surface after the mesa is processed and formed (this method is widely used now). So the visual effect is surprisingly good, but after a period of use, it will show the original appearance.
pigment
Pigment can also be called natural color paste. Look carefully at the countertops of any series of DuPont products, and then take a sample of other unnatural color paste brands to find out whether the color is natural or not. The raw material price ratio of natural color paste and artificial color paste is 15: 1. Non-natural color paste must have been processed extra, and it will involve some chemical components more or less, so it is not as natural as environmental protection. And the general artificial stone is to make your visual effect good. Artificial pigments are soaked in an adhesive to make them float on the surface. After a long time or more polishing times, even if only 0.2 mm is polished at a time, it may be polished to the day when there is no pattern on the surface! !
