Abstract

The invention relates to polypropylene material with a paint spraying effect. The polypropylene material comprises the following components by weight percent: 38-99.9% of polypropylene, 0-1% heat stabilizer, 0-1% lubricant, 0-15% flexibilizer, 0-5% interfacial compatilizer, 0-30% inorganic mineral powder and 0.1-10% superfine aluminium powder, wherein the particle diameter of the superfine aluminium powder ranges from 1 to 100 Mum. The polypropylene material has excellent surface scratch resistance and superior comprehensive mechanical property, and the surface of the polypropylene material is smooth and glossy like paint. The polypropylene material can be obtained through extruding granulation with a screw rod, the preparation method is simple, and the technological conditions are easy to control. When the polypropylene material is used to manufacture exterior trimming parts of an automobile, the procedure of paint spraying can be omitted on the condition that the service performance and the attractiveness are not influenced, so as to simplify technological process, lower production cost, reduce volatilization of VOC (Volatile Organic Compound) gas and achieve the purposes of energy conservation and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polypropylene material with paint spraying effect and a preparation method thereof. Background technique [0002] Due to the light weight and low price of polypropylene material, most cars now use polypropylene composite materials for exterior trim. However, after the production of many exterior trim products of automobiles, a process of spraying paint is added to improve the appearance and protect against scratches. On the one hand, this will increase the cost of automobile manufacturing. On the other hand, since most paints are solvent-based, they will produce volatile organic solvents (VOC) and pollute the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a polypropylene material with paint spraying effect, which does not need to be ...
