Problems solved by technology

[0008] The above matte technologies all have certain limitations. For example, the addition of fillers will lead to inconsistencies in the continuous phase of the matrix, which will easily cause defects in mechanical properties and appearance, especially the hidden dangers of weld lines during processing; a large amount of rubber and epoxy The addition will greatly affect the fluidity of the resin and reduce the rigidity of the material, thus limiting the application of the material to a certain extent, especially under the development trend of thin-walled industry, the lower fluidity will have greater disadvantages; Relying on the mold design has a strong dependence on the processing conditions of the material, and the applicability is not wide

Abstract

The invention relates to a PC / ABS composition and its preparation method and application. The PC / ABS composition includes components such as polycarbonate, ABS, acrylic shell silicone rubber, polyurethane, toughening agent, antioxidant and lubricant. The PC / ABS composition provided by the present invention improves the gloss by adding acrylic shell silicone rubber and polyurethane, and gives the PC / ABS composition a better matte effect, which can meet the needs of various processes for gloss; in addition, it can also Greatly improve the processing fluidity of PC / ABS while maintaining high strength and toughness.

Description

technical field [0001] The invention belongs to the field of engineering plastics, and in particular relates to a PC / ABS composition and a preparation method and application thereof. Background technique [0002] PC / ABS is a traditional high-performance alloy with beneficial characteristics such as high surface gloss, good toughness, and good processing fluidity. It is used in various fields, especially engineering plastics technology in the fields of electronics, transportation, and building materials. field. With the development of the industry, the requirements for the diversification of material appearance are getting higher and higher. For example, for automotive interior parts, it is necessary to pay attention to the reflectivity of the instrument panel when designing. It is necessary to improve the visibility of the instrument and reduce glare through the diffuse reflection method of the instrument cover. The inner surface forms a reflective image so as not to inter...
