Problems solved by technology

Adding mica and carbon fiber to improve the performance loss caused by a large number of elastomers is not only costly but also complex in processing technology. The specific color of carbon fiber limits its use in areas with color requirements
[0007] In summary, there is currently a lack of a new material with low cost, high performance, beautiful appearance, low surface gloss, soft touch and simple preparation

Abstract

The invention relates to low-gloss soft-touch modified thermoplastic resin and a preparation method thereof, and belongs to the technical field of modified plastics and composite materials, the low-gloss soft-touch modified thermoplastic resin comprises the following substances by weight: 40-80 parts of thermoplastic resin; 10-40 parts of elastomer master batch; 0-20 parts of nylon; 0-30 parts ofinorganic mineral powder; 0-6 parts of a compatilizer; 0-2 parts of a coupling agent; 0.01-2 parts of an antioxidant; 0-2 parts of a colorant; 0.5-2 parts of a flow modifier; 0.2-1 part of lubricant.The modified thermoplastic resin prepared by the method is relatively low in cost; smooth and attractive appearance, the product has low glossiness and high performance, soft touch can be improved, the preparation method is simple, operation is completed in one step, the product can be widely applied to the fields of automobile industry, daily home furnishing, electrical equipment, construction and building materials, safety labor protection and the like, meanwhile, the production process is simple, original production equipment is used, and additional investment for purchasing equipment is not needed; the raw material cost is low and the product added value is high. Therefore, the device can be widely used and popularized.

Description

technical field [0001] The invention belongs to the technical field of modified plastics and composite materials, in particular to a modified thermoplastic resin with low gloss and soft touch and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the quality of life. Taking automotive instrumentation materials as an example, it is not only required to have beautiful textures, suitable colors, meet safe physical performance indicators, but also need to present comfortable visual and good tactile effects. [0003] JP510177 discloses a reinforced polypropylene composition, the components include 5-90% by weight of soft polypropylene material, 5-60% by weight of mineral or glass fiber and processing aids, etc., with good scratch resistance Sex and soft touch. In the above reports, in order to improve the fluidity of the material, a certain amount of peroxide needs to be added; in ...
