In oil, the methoxy benzophenone of 2- hydroxyls -4,2,2' dihydroxy 4,4' dimethoxy benzophenone -5,5'- sodium disulfonates
A kind of or its mixture.
Preferably, the damage resistant agent, is made up of by weight following components：N, N'- ethylene bis stearamide 10-30
Part, dimethicone 5-10 parts, methoxy benzophenone 5-10 parts of 2- hydroxyls -4,2,2'- dihydroxy -4,4'- dimethoxys two
20-40 parts of Benzophenone -5,5'- sodium disulfonates.
The preparation method of described automobile decoration piece polypropylene-nylon composite materials, it is characterised in that by following step group
Into：
(1) stirring in super mixer is added, extruded machine extruding pelletization is obtained plastic grain；
(2) by injection moulding in above-mentioned plastic grain addition injection machine, automobile decoration piece polypropylene-nylon is obtained multiple
Condensation material.
Obviously, it is in the present invention other performances of raising product, adds to the property of may also adapt to other auxiliary agents, it is such as fire-retardant
Agent, colouring agent and age resister etc..
Nylon 6, polyamide -6 are called PA6.No. CAS：25038-54-4.
2- acrylamidos -3 Methylbutanoic acid, No. CAS：38486-53-5.
GMA, No. CAS：106-91-2.
