Description
Technical field:
The present invention relates to polymer modification fields, the more particularly, to low-luster polypropylene of automotive interior material
And preparation method thereof.
Background technique:
Polypropylene (referred to as: PP) material due at low cost, light weight, chemical-resistance is good, processing performance is excellent, Yi Huishou
The advantages that, it is widely used in automobile and household electric appliances in recent years, is applied especially to inner and outer decorative parts of automobile, such as: door internal decoration plate, instrument
Plate, column, seat backplate, bumper, side encirclement, deflector, mud guard etc..With the improvement of people's life quality, people couple
Comfort and requirement in car steering room is also higher and higher, if the glossiness of plastic ornament is higher in driver's cabin, just has
Stronger light reflection, to influence the comfort of driver.Therefore in recent years, many automobile main frame maker require vapour one after another
Vehicle developing material quotient develops the polypropylene interior material of low gloss to adapt to the demand in market.
The method for reducing material glossiness at present is roughly divided into three classes:
1, coated matte paint reduces surface gloss on automotive material product, increases production process and is produced into
This.
2, texture processing is carried out to mold, so that the article surface got has lines to reduce surface gloss, increases mould
Have development cost and article surface easily hides ash and is not easy to clean.
3, processing is modified to automotive material itself, adds some delustering agents, such as: silica, talcum powder, calcium carbonate
Deng.But addition the above material need to control partial size in 5 microns, and additive amount is best in 5 ~ 10% effects, right this institute
It calls that optimal extinction effect is also very unsatisfactory, still can not meet requirement of certain main engine plants to low-luster polypropylene material.
Summary of the invention:
