Problems solved by technology

[0003] Existing sanitary products are generally made of ceramics. However, ceramic materials have problems such as heavy weight, low processing performance, and unfavorable transportation. Therefore, there is an urgent need for a new material that can replace ceramic materials to manufacture sanitary products and solve the original Problems posed by ceramic materials
[0004] Toughened SAN is a kind of plastic with excellent comprehensive properties. It has excellent impact resistance, good low temperature performance and chemical resistance, good dimensional stability, and good surface gloss of products. However, toughened SAN has some defects. Such as poor weather resistance, because of the presence of butadiene rubber in the toughened SAN material, the bond energy of the C=C double bond is low. After being stimulated by light and heat, the C=C double bond will be in a shorter The double bond breaks within a short period of time, resulting in a decrease in the performance of the material and a change in the color of the product;
[0005] PMMA has excellent transparency and good scratch resistance, but PMMA has low notched impact strength, poor toughness, sensitivity to notches, and poor processability, which greatly limits its application.
[0006] Patent CN 106854318 A, published on June 16, 2017, discloses a SAN / PMMA composite material for sanitary ware without spraying and its preparation method. In this technical solution, only the SAN material and PMMA are simply combined On the one hand, it is still unable to completely overcome the shortcomings of toughened SAN and PMMA materials, and the physical properties are still not enough to meet the use of sanitary products; on the other hand, in the sanitary environment, due to the use of various detergents, acid-base The environmental changes are more severe, and the acid and alkali resistance of general SAN / PMMA composite materials used for sanitary ware is not as good as that of ceramic materials.

Abstract

The invention relates to the field of bathroom materials and in particular relates to an SAN / PMMA (Styrene-Acrylonitrile / Polymethyl Methacrylate) composite material for bathrooms and a preparation method thereof. The composite material is prepared from the following raw materials in parts by mass: 10 to 30 parts of a toughening agent, 30 to 55 parts of SAN, 15 to 40 parts of PMMA, 3 to 10 parts ofa styrene-acrylonitrile-maleic anhydride copolymer, 0.5 to 3 parts of a brightening agent, 0.5 to 3 parts of a light stabilizer, 0.5 to 3 parts of an anti-scratching agent and 0.5 to 2 parts of otherauxiliary agents, wherein the other auxiliary agents comprise at least one of a lubricant and an antioxidant. The SAN / PMMA composite material for the bathrooms, provided by the invention, can be usedfor manufacturing bathroom products and can meet special requirements on bathroom product materials, such as high luster, scratching resistance, weather resistance and acid and alkali corrosion resistance; the problems that existing ceramic bathroom products have relatively great weight, are inconvenient to transport, are easy to damage in a transportation process, have complicated processing procedures and relatively single color and the like can be improved; the SAN / PMMA composite material for the bathrooms has relatively good application market and prospect in the field of the bathrooms.

Description

technical field [0001] The invention relates to the field of bathroom materials, in particular to a SAN / PMMA composite material used in bathrooms and a preparation method thereof. Background technique [0002] Sanitary ware, as a must-have for every household, occupies a certain basic market share, and smart sanitary ware has great potential in this industry, and plays an important role in the market. Sanitary ware products are constantly developing and changing, and competition is also intensifying. my country's modern sanitary ware has been developed for more than 20 years. Sanitary ware products have initially met the functionality, and now they meet the owner's taste and cultural needs; the purchase of sanitary ware has changed from a luxury for a few people to the popularity of the county and township markets. With the gradual maturity of the sanitary ware market, sanitary ware products have also been segmented from a large group of grades at the beginning, and now the...
