The initiator system that the present invention adopts is two kinds, comprise initiator A and initiator B, described initiator A or initiator B are preferably dibenzoyl peroxide, 1, two (t-butylperoxy di-isopropyl) benzene, 1 of 4-, two (t-butylperoxy di-isopropyl) benzene, 2 of 3-, 5-dimethyl-2,5-(two tert-butyl peroxy bases) hexane, 2,5-dimethyl-2,5-(two tert-butyl peroxy bases)-3-is alkynes, ethyl-3,3-bis-(tert-butyl peroxy base) butyric ester or ethyl-3, a kind of in 3-bis-(tert-pentyl peroxy) butyric ester, initiator A or B are material not of the same race.
Two kinds of different initiators composite, make initiator system possess the different transformation period, thereby can avoid the too quick decomposition of single initiator initiator in extrusion, guarantee all to have more initiator free radical in each stage of extruding, guarantee the high percentage of grafting of product, reduce the residual of polar monomer, thereby prevent the problems such as resin produces variable color and smell is large.
In addition in the present invention, also proposed to prepare the method for above-mentioned polypropylene resin composite, the method comprises the steps:
A. according to recipe ratio, acrylic resin is added from extruder main spout;
B. polar monomer, the second monomer, initiator A, initiator B are pressed to proportioning after acetone solution simultaneously, by volume pump, be injected in forcing machine, the forcing machine that inlet is positioned at described in the 3rd heating zone of forcing machine comprises twin screw extruder or single screw extrusion machine, and its extruding zone has seven above heating zone;
C. through extruding pelletization, be also dried and obtain described polypropylene resin composite.
Preparation method of the present invention adopts batch mixing and reinforced mode to carry out, wherein acrylic resin is added from the main spout of forcing machine, other components add from being positioned at the inlet of the 3rd heating zone, make acrylic resin can fully contact, mix with other components in the situation that being subject to thermal softening melting, can effectively guarantee feeding, can make again mixture fully disperse, merge and react.Avoided traditional method to cause initiator fast decoupled in disposable adding of spout, make at the posterior segment of forcing machine initiator free radical very few, thereby it is low to produce grafting efficiency, the situation that maleic anhydride monomer residual quantity is high.
In preparation method, described acrylic resin be complete with or one or more combination of a same homo-polypropylene, atactic copolymerized polypropene, block copolymerization polypropylene; Described polar monomer is a kind of in maleic anhydride, vinylformic acid and derivative thereof, and described acrylic acid derivative comprises methyl methacrylate, β-dimethyl-aminoethylmethacrylate, butyl methacrylate or glycidyl methacrylate; The second described monomer is vinylbenzene, iso-butylene, long-chain monoene alkene, and long-chain monoene alkene comprises the isometric strand alkene of 1-octadecylene.
In preparation method, described initiator system comprises initiator A and initiator B, initiator system can be selected any two kinds from following material: dibenzoyl peroxide, 1, two (t-butylperoxy di-isopropyl) benzene, 1 of 4-, two (t-butylperoxy di-isopropyl) benzene, 2 of 3-, 5-dimethyl-2,5-(two tert-butyl peroxy bases) hexane, 2,5-dimethyl-2,5-(two tert-butyl peroxy bases)-3-is alkynes, ethyl-3,3-bis-(tert-butyl peroxy base) butyric ester or ethyl-3,3-bis-(tert-pentyl peroxy) butyric ester.Initiator A and initiator B are material not of the same race, can make like this initiator system have the different transformation period, and guaranteeing all has in each stage of extruding the initiator free radical that content is higher, has effectively guaranteed high percentage of grafting.
