Description
Technical field
The present invention relates to technical field of polymer materials, polyphenylene sulfide composite modification material particularly relating to a kind of hydrolysis and preparation method thereof.
Background technology
Polyphenylene sulfide (PPS) also claim polyphenylene sulfide, and its over-all properties is better, high temperature resistant, corrosion-resistant, radiation hardness, do not fire, and possess good mechanical property and electrical property, and thus polyphenylene sulfide is the preferred material of electronics, appliance field.
At present, because plastics can moisture absorption thus cause that plastic part fast hydrolyzing is aging cannot enter drinking water related product field then.And agent of low hygroscopicity material as materials such as PPO, PEEK because its price is high, many reasons such as processing difficulties still cannot meet industry service requirements of paddling, current the used plastics of industry of paddling all adopt the mode of vacuum metallization to slow down its hydrolysising aging, and technical process is very complicated.
Summary of the invention
The present invention proposes a kind of polyphenylene sulfide composite modification material of hydrolysis, to solve the aging technical problem of current PPS material fast hydrolyzing.
The present invention adopts following technical scheme to realize:
A polyphenylene sulfide composite modification material for hydrolysis, it presses percentage composition than formulated by the raw material of following proportioning:
Wherein, described hydrolysis-resisting agent is that carbodiimide is or/and epoxy compounds.
Wherein, described antioxidant is N, N'-pair-(3-(3,5-di-tert-butyl-hydroxy phenyl) propionyl) hexanediamine (1098) or β-positive octadecanol ester (1076) of (3,5-di-tert-butyl-hydroxy phenyl) propionic acid.
Wherein, described auxiliary chemicals are N, N '-bis-ethylene fatty acid amide (TAF) or silicone powder.
Present invention also offers a kind of preparation method of polyphenylene sulfide composite modification material of above-mentioned hydrolysis, comprise step:
A, will add in the high-speed mixer of 500-2000 rev/min than the polyphenylene sulfide powder taken by percentage composition, make its temperature reach 80 ~ 100 DEG C under high velocity agitation;
B, add silane coupling agent, vinyl silicone oil, silane coupling agent, hydrolysis-resisting agent be activated to 105 ~ 110 DEG C make the related substances condition of high temperature under full cross-linked, then go to low speed constant 105 ~ 125 DEG C 10 minutes, add antioxidant, auxiliary chemicals mix;
C, said mixture to be added in 36:1 major diameter twin screw extruder with 295 DEG C-315 DEG C for processing temperature, add the blended granulation of alkali free glass fibre at Section five in opening cylinder.
Compared with prior art, the present invention has following beneficial effect: the invention enables polyphenylene sulfide to have hydrolysis, high-low temperature resistant, the advantages such as acid and alkali-resistance, realizes replacing copper material, steel paddling in industry, thus reaches the object reduced costs; And effectively can extend product work-ing life, improve the phenomenons such as processing difficulties.
