Abstract
Disclosed are an automobile environment-friendly brake hose and a preparation method thereof. Raw material components of the automobile environment-friendly brake hose include, by weight, 100 parts of ethylene-propylene-diene monomers, 90-120 parts of carbon black, 15-30 parts of 828-type plant based rubber filling oil, 5-10 parts of epoxidized soybean oil, 1-3 parts of nano zinc oxide, 1-3 parts of stearic acid, 2-5 parts of accelerators and 3-5 parts of sulphur. Compared with the prior art, the automobile environment-friendly brake hose has the advantages that both the 828-type plant based rubber filling oil and the epoxidized soybean oil are nonpoisonous and tasteless plasticizers which are safe and environment-friendly, contain no polycyclic aromatic hydrocarbons limited by the REACH (registration, evaluation, authorization and restriction of chemicals) and have no harmful volatile substances during preparation and use as compared with conventional plasticizers such as naphthenic oil and aromatic oil; both the 828-type plant based rubber filling oil and the epoxidized soybean oil come from plants and accordingly have remarkable cost advantages; vulcanizing time is short, production period is short, and energy consumption is low; and compared with an existing brake hose, the automobile environment-friendly brake hose has high hardness and tensile strength and good properties of heat resistance and aging resistance.
Description
Technical field
The present invention relates to auto parts machinery, more specifically, relate to a kind of automobile environment-protection brake rubber pipe and preparation method thereof.
Background technology
Along with the raising of people's living standard, automobile has become one of vehicles of people.The breaking system of automobile is at car deceleration or requisite system while stopping, and breaking system comprises stopper and brake rubber pipe.Brake rubber pipe is the vitals that automobile is improved quality and required very strictly, is related to vehicle and personnel safety.Brake rubber pipe, except resistance to braking fluid, also must have good ageing-resistant performance and moisture vapor transmission properties etc.Aromatic hydrocarbon oil large usage quantity in existing rubber oil product, and aromatic hydrocarbon is universally acknowledged carcinogens, contains condensed-nuclei aromatics (PAHs) composition.The brake rubber pipe of producing with the high aromatic rubber oil of tradition, in use carcinogens can evaporate.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of automobile environment-protection brake rubber pipe and preparation method thereof is provided.
According to an aspect of the present invention, a kind of automobile environment-protection brake rubber pipe, each feed composition content proportioning is by weight: terpolymer EP rubber 100, carbon black 90～120,828 plant base rubber filling oils 15～30, epoxy soybean oil 5～10, nano zine oxide 1～3, stearic acid 1～3, promotor 2～5, sulphur 3～5.
According to another aspect of the present invention, a kind of preparation method of automobile environment-protection brake rubber pipe, each feed composition content proportioning is by weight: terpolymer EP rubber 100, carbon black 90～120,828 plant base rubber filling oils 15～30, epoxy soybean oil 5～10, nano zine oxide 1～3, stearic acid 1～3, promotor 2～5, sulphur 3～5;
After above-mentioned raw materials is mixing, extrusion moulding, vulcanize, curing temperature is 150～170 ℃, and curing time is 15～30min.
Described promotor can be sulfate-phosphate derivative or CZ.
Than prior art, the present invention at least has the following advantages:
1) 828 plant base rubber filling oils and epoxy soybean oil are nonpoisonous and tasteless softening agent, compare with aromatic hydrocarbons wet goods with conventional softening agent naphthenic oil, safety and environmental protection, not containing the PAHs material of REACH regulation limitations, the objectionable impurities of can not volatilizing in preparation process and use procedure.
2) 828 plant base rubber filling oils and epoxy soybean oil all derive from plant, belong to renewable resources, than take the conventional softening agent of oil as raw material refining, have significant cost advantage.
3) curing time is short, with short production cycle, and energy consumption is low;
4) compare with existing brake rubber pipe material, there is larger hardness and tensile strength and heat-resisting, oxygen aging performance preferably.
