Description
Technical field
The present invention relates to a kind of low gloss that can be used for automotive upholstery, resistance to scratching PP composite material and its preparation sides
Method is mainly used for automotive upholstery, belongs to polymer modification and processing technique field,
Background technique
With the rapid development of the automotive industry, it as automobiles plastics maximum kind polypropylene material, is used extensively
In inner and outer decorative parts such as bumper, instrument board, door-plate, columns.Along with the application development of automobile-used PP composite material, Ren Menfa
Now there can be the higher phenomenon of gloss by part prepared by PP composite material, especially apply in vehicle inside decoration part part, this
May be related with the characteristic of mold dermatoglyph, at the same may also can increasing with component die product quantity, the light of mold body
Pool, which increases also improve, causes the gloss for preparing part to increase.For exposed automotive upholstery, part gloss is higher
Stronger light can be brought to reflect later, this will will affect the comfortable and safety of interior driver and passenger.
That there are surface hardnesses is lower for polypropylene material simultaneously, itself Marresistance can be general, by PP composite material system
The product surface of standby some exposed automotive upholsteries is easy to be scratched, and influences the quality of product, more especially pair product
The higher texture gadget of performance requirement is scratched on surface, such as the rough bark lines of some complexity, geometry dermatoglyph, special color gadget, sharp
Light 3D texture gadget, these more special gadgets can requirements with higher to the Marresistance of PP composite material.
Summary of the invention
The present invention is primarily to the above-mentioned polypropylene material for automobile interiors of solution is higher compared with the gloss often met and scratch-resistant
Not foot phenomenon is wiped, a kind of low gloss can be used for automotive upholstery, resistance to scratching PP composite material and preparation method thereof are provided.
