Embodiment Construction

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the examples.

[0027] A low-density polypropylene composite resin composition for automobiles, the material components of which include high-crystalline polypropylene, a reinforcing agent, and an impact modifier. The weight percentage of any composition in the material component is:

[0028] 30wt% to 75wt% of high crystalline polypropylene with an isotactic index of more than 96%,

[0029] 10wt%~35wt% reinforcing agent,

[0030] 15wt% to 35wt% impact modifier.

[0031] The reinforcing agent is selected from the reinforcing agent comprising hollow microspheres, and the weight ratio of the hollow microspheres and the reinforcing agent after mixing is 1:1~1:10, preferably 1:3~1:10 or 1:5~1: 10 is appropriate. If the content of hollow microspheres in the reinforcin...

Abstract

The present invention relates to the technical field of vehicle materials, particularly to a low-density vehicle polypropylene composite resin composition, which comprises, by weight, 30-75 wt% of high-crystallinity polypropylene having an isotactic index of more than 96%, 10-35 wt% of a reinforcing agent, and 15-35 wt% of an anti-impact modifier, wherein the reinforcing agent comprises hollow microbead, and a weight ratio of the hollow microbead to the reinforcing agent is 1:1-1:10. Compared to the composition in the prior art, the composition of the present invention has the following characteristics that the rigidity and the heat resistance of the product are maximized by using the talc and the hollow microbead in the high-crystallinity polypropylene through the technical scheme, such that the rubber content for achieving the impact strength of the vehicle material can be ensured; and the low-density polypropylene resin composition having the balance among the rigidity, the heat resistance and the impact strength is produced, and can be widely used for interior and exterior devices of vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile materials, in particular to a low-density polypropylene composite resin composition for automobiles. Background technique [0002] The international environment has increasingly strict requirements on environmental protection, so the requirements on vehicle emissions have also become increasingly stringent. Under the circumstances that there is no major breakthrough in engine technology, the cost of electric motor gasoline-electric hybrid vehicles remains high, and the acceptance of the public is still low, the method of reducing the total quality of the vehicle without reducing the safety of the vehicle has been favored by the current major automobile manufacturers. recognized. As an indispensable plastic part in automobile components, the lightweight of plastic parts has gradually become a trend in automobile design and manufacturing. [0003] As a material for automobiles, polypropylene co...
