Abstract

The invention relates to a foamed polypropylene material used for an automobile ceiling. The foamed polypropylene material comprises (by weight) 40 to 80 parts of polypropylene random copolymer, 15 to 30 parts of high-density polyethylene, 15 to 25 parts of low-density polyethylene, 4 to 12 parts of a foaming agent and 0.5 to 2 parts of a cross-linking agent. The invention has the following beneficial effect: through addition of the above-mentioned components, the low-ratio foamed polypropylene material used for the automobile ceiling is prepared.

Description

A kind of polypropylene foam material for roof of the vehicle
Technical field
The present invention relates to a kind of foam polyolefin material, relate in particular to a kind of polypropylene foam material for roof of the vehicle.
Background technology
Polypropylene material is due to its good environmental-protecting performance, and its using value is more and more valued by the people.For example for the polypropylene foam material of roof of the vehicle there is easy recovery, the advantage such as high temperature resistibility is strong, chemical resistance good, sound insulation buffering, insulation.But in existing polypropylene product, be difficult to obtain the polypropylene foam material for roof of the vehicle of low range.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of polypropylene foam material for roof of the vehicle of low range is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of polypropylene foam material for roof of the vehicle, and described material consists of the following composition (according to weight part proportioning):
Atactic copolymerized polypropene 40-80 part
High density polyethylene(HDPE) 15-30 part
Low Density Polyethylene 15-25 part
Whipping agent 4-12 part
Linking agent 0.5-2 part.
The invention has the beneficial effects as follows: by adding of said components, obtain a kind of polypropylene foam material for roof of the vehicle of low range.
Embodiment
Be described below in conjunction with principle of the present invention and feature, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment 1
For a polypropylene foam material for roof of the vehicle, described material consists of the following composition (according to weight part proportioning):
40 parts of atactic copolymerized polypropenes
30 parts of high density polyethylene(HDPE)s
