Polypropylene resin composition for creating fabric texture

Abstract

According to preferred aspects, the present invention provides a polypropylene resin composition for creating a fabric texture, the polypropylene resin composition comprising: a polypropylene resin containing at least two selected from the group consisting of a homopolypropylene, a propylene-ethylene copolymer, and a high crystalline polypropylene (HCPP); a polypropylene elastomer; an ethylene-[alpha]-olefin copolymer; an inorganic filler; a cellulose fiber; and a volcanic rock. A molded product prepared using the polypropylene resin composition of the present invention has matt properties, do not cause odor due to their excellent VOC adsorption capabilities, and have excellent properties such as low temperature impact resistance, scratch resistance, etc.

Description

technical field [0001] The present invention generally relates to polypropylene resin compositions for producing textile textures. More specifically, the present invention relates to a polypropylene resin composition comprising: a polypropylene resin containing at least two selected from the group consisting of homopolypropylene, propylene-ethylene copolymer and high crystalline polypropylene (HCPP); polypropylene elastic ethylene-α-olefin copolymers; inorganic fillers; cellulose fibers; and volcanic rocks. Background technique [0002] Due to the trend of high-quality vehicles in recent years, plastic parts for vehicle interior parts such as door trims, pillar trims, etc. are required to be of excellent quality. Therefore, in order to improve vehicle interior quality, fiber covering or coating is used for plastic parts used for vehicle interior parts. However, the method of wrapping or coating plastic parts using fibers has some disadvantages, such as cost increase due to...

Problems solved by technology

However, the secondary process leads to entanglement of the cellulose fibers and a reduction in their size, so when the resulting resin is used in plastic parts for vehicle interior parts with an embossed surface, the texture of the fabric is reduced, instead due to the additional process Increased processing costs

In addition, the existing cellulose fibers or synthetic cellulose fibers are carbonized at about 250°C, so the cellulose fibers are burned or discolored during the injection molding of plastic parts, thus degrading the quality of the plastic parts
