Problems solved by technology

However, the spraying process requires the use of a large amount of paint, organic solvents, etc., which not only consumes a lot of manpower and material resources; more importantly, the paint has a high content of toxic and harmful organic volatiles, which seriously affects the health of operators and pollutes the air environment. Requirements for environmental protection and sustainable development
Therefore, these shortcomings limit the use of polypropylene composite materials in automotive exterior parts, especially limit the use of polypropylene in exterior parts with high requirements for scratch resistance. Therefore, it is necessary to improve polypropylene composite materials. Scratch resistance and aesthetic properties can broaden the application range of polypropylene

Abstract

The invention relates to a spraying-free scratch-resistant polypropylene composite material used for car exterior trimming parts and a preparation method of the composite material. The spraying-free scratch-resistant polypropylene composite material is prepared from the following components in parts by weight: 39.6-77.1 parts of polypropylene, 5.0-8.0 parts of high-density polyethylene, 0-15 parts of flexibilizer, 15-25 parts of filler, 0.2-1 part of antioxidant, 1.0-5.0 parts of scratch resistant agent, 0.5-1 part of lubricant, 0.2-0.4 part of light stabilizer, 1.0-5.0 parts of metal toner. According to the spraying-free scratch-resistant polypropylene composite material disclosed by the invention, the metal toner and the scratch resistant agent are adopted, so that the polypropylene composite material has metallic luster effect and scratch resistance, has spraying-free effect and further has scratch resistance at the same time, and therefore, application field of the polypropylene is expanded, and the spraying-free scratch-resistant polypropylene composite material is especially applicable to using on the field of car exterior trimming parts.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a non-spraying and scratch-resistant polypropylene composite material for automobile exterior trims and a preparation method thereof. [0002] Background technique [0003] Polypropylene (PP) has become one of the fastest-growing varieties of plastic production due to its simple synthesis method, abundant raw material sources, low price, and good physical and mechanical properties and processing properties. Its output ranks first among the five general-purpose plastics. Three, and has a large number of applications in the automotive field. [0004] Polypropylene (PP) is widely used in the automotive industry due to its excellent heat resistance, good bending fatigue resistance, and low price. However, PP has low impact toughness, poor creep resistance, large molding shrinkage, and poor dimensional stability; polypropylene composite materials are generally not resistant to scra...
