Abstract

The invention relates to a fabric tactility imitated automotive polypropylene material which is characterized by comprising polypropylene, a flexible modified material, lamellar mica powder and flakyglass flakes, wherein the flexible modified material is at least one substance selected from a styrenic thermoplastic elastomer, a block organic silicon material and polyethylene wax. According to theinvention, by adding the styrenic thermoplastic elastomer, the block organic silicon material and the polyethylene wax, soft tactility is given to the polypropylene material; and meanwhile, additionof the lamellar mica powder and flaky glass flake fillers takes an effect of a skeleton, so that a polypropylene base material has a certain texture while obtaining the tactility and a hand feeling iscloser to a fabric hand feeling.

Description

technical field [0001] The invention relates to the field of polypropylene materials, in particular to a polypropylene material for fabric-like touch vehicles. Background technique [0002] With the improvement of the quality of life, consumers have higher and higher requirements for the quality of car interiors, accessories and household appliances; taking the dashboard of car interiors as an example, hard dashboards are often used in economical models or tough SUVs , that is, PP injection molding, this material has a strong sense of plastic and cannot give people a soft texture, and often cannot satisfy the warm and luxurious decoration style. [0003] "Fabric-like touch" is a property of plastic parts. When you touch the surface of the part with your hands, you will feel a certain degree of softness, but at the same time it is different from the rubber touch, and it also has a certain texture / skinny feeling. Contents of the invention [0004] The invention overcomes th...
