Description
Technical field
The present invention relates to a kind of instrument board, specifically a kind of combined type shock resistance bumper raw material.
Background technology
Bumper has the effects that safeguard protection, decoration vehicle and the air dynamic behaviour for improving vehicle.From safety
On see, automobile occurs to can play a buffer role in when low speed collision accident, protects front and back car body；It can be with when accident occurs with pedestrian
Play the role of certain protection pedestrian.From the appearance point of view, with dicoration, become the important component of decoration car appearance；Together
When, bumper also has certain aerodynamic action.In order to reach this purpose, the front/rear collision bumper of car is adopted at present
With plastics, people are known as plastic bumper.
For PP materials increasingly close to people’s lives, the thing followed is the increase of PP bumper materials usage amounts,
With PP bumpers materials mostly easy to aging, not impact resistance, not acid-alkali-corrosive-resisting and it is not wear-resisting, resistance to low temperature is low the problems such as
Show.
Existing PP bumpers materials mainly use PP and POE, talcum powder to be formed by combining, Chinese patent
CN102516665A discloses the preparation method of a kind of PP and copolymerization PP bumper PP Pipe Compounds, using PP and copolymerization PP,
POE and bismaleimide are composed, but the Shortcomings in terms of shock resistance；Chinese patent CN101781424A is disclosed
A kind of formula and processing technology of the bumper with metallic luster, is composed using PP, POE and aluminium powder, wear-resisting, but
It is in terms of allowing for shock resistance or relatively low, therefore a kind of PP bumpers materials of design are very important.
