Abstract
The invention discloses a heat resistant chloroprene rubber composition for an automobile dust cover. The heat resistant chloroprene rubber composition comprises the following components, wherein the components comprise, by mass, 43-44% of chloroprene rubber, 0.3-0.5% of stearic acid, 1.5-2% of magnesium oxide, 4.5-5.5% of an anti-aging agent, 30-31% of carbon black, 10.5-11.5% of grease, 2-2.5% of zinc powder, 0.6-1.0% of polymer wax, 0.6-1% of paraffin, and 3-3.5% of a vulcanizing agent. The heat resistance of the chloroprene rubber rolled by the formula of the present invention is substantially improved, the requirement at a high temperature of 120 DEG C can be met, and the chloroprene rubber can work at the high temperature of 130 DEG C for a short time.
Description
Technical field
The present invention relates to be used for the field of rubber materials of automobile component, more particularly, relate to a kind of neoprene latex compsn that is used for vehicle dust protector.
Background technology
Vehicle dust protector is to protect grease on the automobile driving axle, the rubber bushing of dustproof, leakproof.Vehicle dust protector use temperature before generally can be above 100 ℃.Because the continual renovation of car industry new model is regenerated, and is also increasingly high to the performance requriements of component, a lot of customer requirement dw products will long term operation under 120 ℃ high-temperature hot oil.Have the dw of a lot of new models near vapor pipe, to work at present, working temperature surpasses 110 ℃, and the short period of time working temperature can reach more than 120 ℃.Present neoprene latex dw can't satisfy this performance requriements.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency that exists in the prior art, and a kind of heat resistant type neoprene latex compsn that is used for vehicle dust protector is provided.
The present invention is used for the heat resistant type neoprene latex compsn of vehicle dust protector, is made up of by said mass percent following component: neoprene latex 43-44%, Triple Pressed Stearic Acid 0.3-0.5%, Natural manganese dioxide 1.5-2.0%, anti-aging agent 4.5-5.5%, carbon black 30-31%, grease 10.5-11.5%, zinc powder 2-2.5%, macromolecule wax 0.6-1.0%, paraffin 0.6-1.0%, vulcanizing agent 3-3.5%.
The present invention is used for the heat resistant type neoprene latex compsn of vehicle dust protector, and optimum ratio is formed by the following stated mass percent: neoprene latex 43.96%, Triple Pressed Stearic Acid 0.44%, Natural manganese dioxide 1.76%, anti-aging agent 5.06%, carbon black 30.77%, grease 10.98%, zinc powder 2.19%, macromolecule wax 0.88%, paraffin 0.88%, vulcanizing agent 3.08%.
The safe working temperature of neoprene latex is-30 ℃～90 ℃, and rubber is aging very fast under thermal oxidation when surpassing 110 ℃, can't long term operation.Wanting to satisfy 120 ℃ of high temperature requirement just must be through adding the material that can significantly improve the neoprene latex resistance toheat.Rubber is the poor conductor of heat, and under overheated condition, rubber part easily amasss heat and causes local defect, causes rubber performance to descend.Metal simple-substance can play conductive force, and natural gum can use big amount zinc oxide as thermally conductive material, but zinc oxide is the vulcanizing agent of neoprene latex, can not use in a large number, so can only add zinc powder.The zine ion of its generation can react with the unsaturated link(age) of rubber and stop its oxidation scission.Use the fill a prescription resistance toheat of rolling neoprene latex of the present invention significantly to improve, can satisfy 120 ℃ high temperature requirement, and can between 130 ℃ of high temperature, short times, work.Material of the present invention and the heat-resisting comparative test result of former neoprene latex material are seen table 1

Embodiment
Below in conjunction with embodiment the present invention is done and to further describe.
Embodiment: the present invention is used for the heat resistant type neoprene latex compsn of vehicle dust protector, presses following composition: neoprene latex 43.96%, Triple Pressed Stearic Acid 0.44%, Natural manganese dioxide 1.76%, anti-aging agent CD 2.64%, anti-aging agent TNP0.44%, antioxidant MB 0.44%, antioxidant 4010NA 0.88%, anti-aging agent 4,020 0.88%, carbon black 30.77%, grease 10.98%, zinc powder 2.19%, macromolecule wax 0.88%, paraffin 0.88%, vulcanizing agent 3.08%.
Above-mentioned materials is mixed with Banbury mixer and mill according to aforementioned proportion sequentially.Use water cooling, store after 24 hours, use rubber injection moulding machine under 170 ℃ of high temperature, to make its sulfidization molding in mould.Take out the preparation of promptly accomplishing vehicle dust protector after cooling off.
Embodiment recited above describes the preferred embodiment for the present invention; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design philosophy of the present invention; Common engineering technical personnel make technical scheme of the present invention in this area various distortion and improvement all should belong to protection scope of the present invention.
