Abstract

The invention relates to a raw material for preparing automobile water pipe outer rubber by combining ethylene-propylene-diene rubber and chlorinated polyethylene rubber, the raw material employs an organic peroxide (BIPB)/a promoter (TAIC) sulfuration system, and comprises the following components by weight: 70-30 parts of ethylene-propylene-diene rubber, 30-70 parts of chlorinated polyethylene rubber, 8-10 parts of magnesium oxide, 1-2 parts of antioxidant RD, 60-90 parts of carbon black N550, 30-60 parts of carbon black N774, 45-70 parts of diatomite, 40-60 parts of paraffin oil, 3-5 parts of vulcanizing agent BIPB and 3-5 parts of crosslinking auxiliary agent TAIC. The raw material has the following effects that 1)the volume expansion ratio of the rubber material for resisting IRM903#oil at 100 DEG C for 70 hours is lower than 60%; 2)the rubber material technical performance is good, and the storage stability is good. The raw material solves the problem of poor oil resistant performance of the automobile water pipe outer rubber, service life of rubber pipe is prolonged, and the raw material is the ideal material used for future automobile water pipe outer rubber.

Description

The outer glue preparation raw material of automobile water pipe of a kind of terpolymer EP rubber and chlorinated polyethylene rubber use
Technical field
The invention belongs to rubber technology field, particularly be the outer glue preparation raw material of automobile water pipe of a kind of terpolymer EP rubber and chlorinated polyethylene rubber use.
Background technology
High speed development along with automobile high performance and rubber industry, water pipe is as an important component part of automobile, because of the requirement of its environment for use and working conditions (a small amount of non-polar oil and hot environment), outer glue need to have the performances such as good heat-resisting, resistance to ozone, oil resistant conventionally.The outer glue of automobile water pipe is normally used is at present terpolymer EP rubber (being called for short EPDM), because terpolymer EP rubber belongs to carbochain saturated nonpolar rubber, there is the performances such as outstanding heat-resisting, resistance to ozone, but nonpolar oils material is not possessed to anti-patience, according to pertinent literature, common EPDM is through resistance to IRM903 #after 100 ℃ * 70h of oil, cubical expansivity can reach 150%, can be lost efficacy by the serious swelling of this oily substance, thereby greatly shortened the work-ing life of sebific duct.Chlorinatedpolyethylene (being called for short CM) has the performances such as good physicals, excellent heat-proof aging, oil resistant, and in its molecular chain, contains nonpolar-CH 2cH 2-structure, can mix and use with arbitrary proportion with terpolymer EP rubber, after also using with terpolymer EP rubber, can greatly improve the oil resistance of sizing material, extending the work-ing life of sebific duct, and have good processing performance, is a kind of ideal material that the outer glue of future automobile water pipe is used.
Summary of the invention
The present invention adopts organo-peroxide (BIPB)/promotor (TAIC) vulcanization system, by special cooperation, makes terpolymer EP rubber and chlorinated polyethylene compound sizing material reach following performance: 1, the resistance to IRM903 of sizing material #after 100 ℃ * 70h of oil, cubical expansivity is in 60%; 2, good, the excellent storage stability of sizing material processing performance.
The technical solution used in the present invention is as follows:
The outer glue preparation raw material of automobile water pipe of terpolymer EP rubber and chlorinated polyethylene rubber use, adopts organo-peroxide (BIPB)/promotor (TAIC) vulcanization system, is made: terpolymer EP rubber, 70～30 by following mass parts component; Chlorinated polyethylene rubber, 30～70; Magnesium oxide, 8～10; Anti-aging agent RD, 1～2; Carbon black N550,60～90; Carbon black N774,30～60; Diatomite, 45～70; Paraffin oil, 40～60; Vulcanizing agent BIPB, 3～5; Crosslinking coagent TAIC, 3～5.
The present invention adopts terpolymer EP rubber V5601(american exxon to produce), chlorinated polyethylene rubber CM6235(Weifang AsiaSat is produced), paraffin oil P-2280(Beijing Ai Dier produces), by above formula, finally reach following effect: 1, the resistance to IRM903 of sizing material #after 100 ℃ * 70h of oil, cubical expansivity is in 50%; 2, good, the excellent storage stability of sizing material processing performance.
