A kind of environment protection, low cost matrix material of alternative flame-proof ABS
Technical field
The present invention relates to a kind of environment protection, low cost matrix material of alternative flame-proof ABS.
Background technology
There are two big technical barriers in PVC and ABS blend: 1) processing stability of PVC is poor; Reason owing to environmental protection; Can not use stabilising effect good but the lead salt and the organic tin stablizer that are restricted; And both differ greatly at processing temperature, under the fused condition, process the thermal destruction that very easily causes PVC, therefore need to solve the stable problem of PVC; 2) PVC and ABS consistency are poor.Owing to except matrix resin, also have stablizer, lubricant etc. in the system, increase both uncompatibilities, therefore need to solve the mutual appearance problem of matrix resin.
Summary of the invention
The environment protection, low cost matrix material that the purpose of this invention is to provide a kind of alternative flame-proof ABS.
The technical scheme that the present invention taked is:
A kind of environment protection, low cost matrix material of alternative flame-proof ABS, its raw material by following mass parts is formed: the fire retarding synergist of the ABS of the PVC of 40-55 part, 25-45 part, the compatilizer of 2-4 part, 0.5-2 part, the flow ability modifying agent of 6-10 part, the softening agent of 1-3 part, the oxidation inhibitor of 0.1-0.5 part.
Described compatilizer comprises a kind of among MBS, CPE, the ACR.
Described fire retarding synergist comprises Antimony Trioxide: 99.5Min, zinc borate, Ammonium Heptamolybdate, zinc oxide.
Described flow ability modifying agent comprises EMI-200, calcium stearate, Magnesium Stearate, N, N-ethylene bis stearamide, PE wax, chlorinatedpolyethylene wax, oleylamide.
Described softening agent is non-phthalic ester plasticizer.
Described non-phthalic ester plasticizer is Dinch.
Described oxidation inhibitor comprises 1010,168,1076,626,1135,215,245.
Described organic stabilizer thiomethyl amphyl, Orgnic rare earth thiolate mixture, metal salt of organic carboxylic acid containing sulfur mixture.
The invention has the beneficial effects as follows: the cost of matrix material of the present invention is lower, is easy to moulding, and resulting matrix material has preferable performance.
