Problems solved by technology

Publication No. CN101121799A patent discloses a method of crosslinking polyethylene molecules by adding a peroxide crosslinking agent to form microgels distributed in the polypropylene matrix. The microgels produce fine protrusions on the surface of the product to cause diffuse reflection of light To reduce the glossiness of the surface of the polypropylene blend modified material, but the matting effect is not ideal

Abstract

The invention provides a polypropylene-use matting agent masterbatch, and a preparation method and an application thereof. The invention relates to the field of plastic modification. The masterbatch comprises the blended materials of, by weight: 100 parts of polypropylene, 20-70 parts of functionalized SBS copolymer, 10-50 parts of fully vulcanized powder silicone rubber, and 5-20 parts of silica. The fully vulcanized powder silicone rubber has an average particle size of 0.05-1mum and a gel content of 60wt% or higher. The average particle size of silica is 1-10mum. With the matting agent masterbatch provided in the invention, polypropylene modified material surface gloss can be substantially reduced. During an application process, matting agent masterbatch dose can be flexibly controlled according to different requirements on gloss. The application method is simple and reliable. The masterbatch can be widely applied in fields such as high-end automotive interior parts.

Description

technical field [0001] The invention relates to the field of plastic modification, in particular to a matting agent masterbatch for reducing the glossiness of polypropylene, a preparation method and application thereof. Background technique [0002] Polypropylene has the advantages of high heat resistance, fatigue resistance, electrical insulation, chemical corrosion resistance, good processability, low price, light weight, and easy recycling, so it is widely used in the automotive industry and other fields. However, most ordinary modified polypropylene materials have the characteristics of gloss or reflection. This defect not only reduces the overall decoration grade of the car interior, but also makes the car driver easy to fatigue, and even affects the driving safety of the car driver, increasing the risk of traffic accidents. probability, and cannot meet the needs of the development of new automotive plastics that can be decorated and integrated. Therefore, low-gloss po...
