Description
Technical field
The present invention relates to modified ABS fields, more particularly to a kind of low smell ABS composite material and preparation method thereof.
Background technology
Requirement of the automobile market to ABS at present is higher and higher, and the material standard of many medium-sized and small enterprises automobile factorys has reached
The standard of internationally renowned brand automobile factory.General ABS in the market cannot generally meet the needs of automobile vendor, especially not
Can meet the needs of automobile vendor's smell.
The material of automobile ABS generally requires to consider heatproof, toughness, and after heat-proof modifier and toughener is added, often
Smell is caused to become worse.For example heat-proof modifier and height is added between 3.5~4.0 in the oder levels of common ABS in the market
Smell is generally at 4~4.5 grades or so after rubber powder.
US6297307 discloses a kind of epoxy resin and oxide improve ABS smell method.But this mixture
Influence of the addition to the mechanical property especially impact property of material it is very big.
The ABS material of low smell, has been respectively adopted Kiselgel A and hydrophobicity disclosed in CN1730542 and CN1730543
Molecular sieve is as eliminating smell agent.But the smell source of modified ABS is various, first, ABS resin matrix is worked as in polymerization process
It is middle to remain some substances (such as emulsifier) with irritant peculiar smell;Secondly, modified ABS material was granulated in melting extrusion
There may be some odorous thermal cracking small molecules in journey;Again, the other ingredients added such as heat-proof modifier, toughening
Agent, stabilizer etc. also bring along certain smell problems.And single eliminating smell agent used by above-mentioned patent often exist it is larger
Limitation.
It is a discovery of the invention that adding odor adsorption agent, small molecule eliminating smell agent, acid absorbent in ABS, made using the collaboration of three
With, it can significantly improve the oder levels of ABS, and on other performances substantially without influence.
Invention content
The object of the present invention is to provide a kind of ABS materials of low smell, have collaboration more particularly to by addition
The smell remover of function of odor removal, to prepare a kind of ABS material of low smell.
In order to achieve the above object, the technical solution adopted in the present invention is a kind of low smell ABS composite material, parts by weights
