High-transparent anti-wear anti-scraping PC (Poly Carbonate) material and preparation method thereof

Abstract

The invention relates to the field of modification of macromolecular thermoplastic materials, in particular to a modified formula of a high-transparent anti-wear anti-scraping PC (Poly Carbonate) material and a preparation method thereof. The modified formula comprises the following substances in parts by weight: 90-98 parts of PC (Poly Carbonate), 1-5 parts of anti-scraping agent, 0.5-3 parts of lubricating agent and 0.5-2 parts of antioxygen. According to the modified PC formula, the surface hardness of a PC resin is improved on the basis of not changing the mechanical property and the transparent property of the PC resin too much, and the application range in the anti-wear anti-scraping engineering plastic field is expanded. The anti-wear anti-scraping PC material disclosed by the invention has excellent flowability and a simple preparation process.

Description

technical field [0001] The invention relates to the field of polymer thermoplastic material modification, in particular to a modification formula of highly transparent, wear-resistant and scratch-resistant PC material and a preparation method thereof. Background technique [0002] PC is polycarbonate, which is the only transparent material among the five major engineering plastics. It has comprehensive properties such as heat resistance and electricity resistance. At the same time, it also has the characteristics of impact resistance, stable size, and flame retardancy. It is widely used in glass assembly industry, automobile industry, electronic appliances and other fields, especially in the automobile industry. PC windows have excellent impact resistance (than ordinary inorganic glass) 250 times higher than the standard polymethyl methacrylate glass sheet, more than 30 times higher), light weight, light transmittance, sound insulation, and heat insulation; Much lower than...

Problems solved by technology

However, PC materials have disadvantages such as low hardness, poor wear resistance, and poor scratch resistance.

Since ordinary PC materials are difficult to meet the needs of the industry, developers can modify PC according to actual needs to adapt to different needs. Many studies have adopted the method of preparing a transparent and wear-resistant coating, which is coated on the poly On carbonate substrates, for example, the patent applied by BASF Coatings Co., Ltd.: polycarbonate with high transparency and scratch-resistant coating, its preparation method and its use, application publication number: CN102216401A, but the method is complicated; there are researchers The wear resistance and scratch resistance of PC materials can be improved by adding PMMA or SAN to PC materials. The disadvantage is that the large amount of PMMA and other substances added affects the transparency of PC materials.
