Problems solved by technology

However, due to the increase of elastomer content in the production process of good-touch glass fiber reinforced polypropylene, the material has the problem of precipitation and stickiness under atmospheric exposure. The current solution is basically to reduce the content of elastomer, but these methods are obvious. The reduced tactile feel of the material

Abstract

The invention relates to a glass fiber-reinforced polypropylene compound with good touch and a preparation method thereof, comprising: polypropylene, toughening agent A, toughening agent B, glass fiber, maleic anhydride graft, nucleating agent, antioxidant agent, light stabilizer. By adding a uniquely compounded toughening agent, the present invention can significantly improve the precipitation and viscosities of the produced polypropylene material with good touch, which can meet the requirements of the popular material standard PV1306, break through the performance bottleneck, and greatly broaden the scope of reinforced polypropylene materials. Applications of propylene in plastic parts for automobiles.

Description

technical field [0001] The invention belongs to the field of polypropylene modification, in particular to a glass fiber reinforced polypropylene compound with good touch and a preparation method thereof. Background technique [0002] As one of the five general-purpose resins, polypropylene has the advantages of light weight, easy processing, and good chemical resistance, and has been widely used in chemical, electrical, packaging and other industrial fields. However, with the gradual expansion of the demand for polypropylene in construction, automobile, shipbuilding and other industries, people have put forward higher requirements for its material properties. Generally, polypropylene is modified to meet more requirements through reinforcement, toughening, blending, etc. application. [0003] Car dashboards can be divided into hard-plastic dashboards and soft-coated dashboards according to comfort. Hard plastic dashboards are usually direct injection molded single-layer pla...
