Problems solved by technology

The modified polypropylene material commonly used in the market is produced by the extrusion molding process. The surface gloss of the outer water cut is low, and the scratch resistance is low. A thin layer of plastic protective film is pasted on its surface, which can greatly reduce the probability of the product being scratched after being subjected to external friction and collision during the process of external water cutting and product use. At the same time, the plastic film can give the product a high gloss on the surface In order to meet the customer's appearance requirements, most of the existing water-cut surfaces of autom...

Abstract

The invention belongs to the technical field of materials for automobile components and parts, and provides a high-gloss scratch-resistant extrusion-grade modified polypropylene material, a preparation method and an automobile external water slot. According to the invention, a brand-new polypropylene modifying formula is designed; formula-related raw materials are premixed through a low-speed mixer and granulated through a twin-screw extruder to prepare a corresponding modified polypropylene material; and the following raw materials are weighed in proportion and uniformly mixed in a low-speedmixing stirrer: PP resin, precipitated barium sulfate masterbatches, a toughening agent, an antioxdiant, an ultraviolet absorber, a nucleating agent, a scratch-resistant agent and self-made high-glossmasterbatches. The modified extrusion-grade polypropylene material provided by the invention has the following advantages: higher glossiness and better scratch resistance are achieved; the requirement of a customer for appearance can be met without lamination of a film; the processing cost pressure brought by the procedure of film lamination is reduced; meanwhile, the novel modified polypropylenematerial can be prepared into different colors according to needs; and more colorful appearance of the automobile external water slot can be given.

Description

technical field [0001] The invention belongs to the technical field of auto parts materials, and relates to a modified polypropylene material, in particular to a high-gloss, scratch-resistant extrusion-grade modified polypropylene material, a preparation method and an automobile exterior water cut. Background technique [0002] At present, most of the exterior water-cut surface materials of automobiles use mineral-filled modified extrusion grade polypropylene materials. The connection between the exterior water cut of the car and the window glass will give people a more intuitive visual experience. Generally, the surface of the water cut outside needs to be smooth and flat, with high gloss and good scratch resistance and weather resistance. The modified polypropylene material commonly used in the market is produced by the extrusion molding process. The surface gloss of the outer water cut is low, and the scratch resistance is low. A thin layer of plastic protective film is ...
