Abstract
The invention discloses a rubber seal cover assembly of a steering shaft of an automobile steering column and a manufacturing process thereof. The rubber seal cover assembly comprises the following raw material components in parts by weight: 90-110 of ternary ethylene-propylene rubber, 65-75 of carbon black, 30-40 of paraffin hydrocarbon oil, 4-6 of indirect method zinc oxide, 1-2 of anti-ageing agent RD, 0.5-1.5 of stearic acid, 1-2 of MOLD FREE935P, 1-2 of silane coupling agent, 0.5-1 of sulphur and 1-2 of composite accelerator EM-33. The manufacturing process comprises the following steps: weighing various raw materials according to the formula requirement; synthesizing rubber in an intermix; carrying out stripping in an open mill; injecting a product obtained in the former step into a mould in vulcanization equipment and then vulcanizing at a certain pressure after heating; and trimming and inspecting the vulcanized product and then entering warehouse. The rubber seal cover assembly of the steering shaft of the automobile steering column prepared by the method in the invention has good breaking strength, elongation at break, tearing strength, rebound resilience, ozone resistance, pollution resistance and adhesion, small odor and the like, thereby ensuring the good seal property and stability of the assembly.
Description
Technical field
The present invention relates to the viton field, be specifically related to a kind of car steering tube column steering shaft rubber seal shade assembly and ME thereof.
Background technology
Vitals-body-lined type steering shaft seal closure assembly as car steering tube column and preceding coaming plate junction; Motor turning, anxious quicken and moving process such as the road conditions of jolting in mainly play sealing and deadening; The noise that prevents mover gets into cab through the steering column hole; The genealogy of law, more Japanese top-of-the-range versions improve riding comfort in this technology of employing at present.This product structure is complicated, and the whole manufacturing process difficulty is bigger, and technology content is very high, and Japan, France are ripe and be in monopoly position in this art at present.This steering shaft rubber seal cover product, performance requriements is harsh, requires to have higher tensile property, tear resistance, rebound resilience, anti-ozone and adhesiveproperties, pollutant performance; Product requires product to have requirements such as low smell and environmental protection near cab.My company tackled key problems through nearly 1 year time, successfully was the project assorted supply of material of Dragon Lord X7, had substituted the product import.
Summary of the invention
To this car steering tube column steering shaft rubber seal shade assembly performance technologies requirement, the purpose of this invention is to provide a cover and have performance steering shaft rubber seal shade assembly and ME thereof such as good rubber tensile strength at yield, tensile yield, tear strength, rebound resilience, anti-ozone, cementability, contaminative and smell are little.
The technical scheme that the present invention is adopted for its purpose of realization: car steering tube column steering shaft rubber seal shade assembly adopts viton; Main raw material is: terpolymer EP rubber, carbon black, paraffinic hydrocarbon wet goods is characterized in that the component weight part of said rubber seal shade assembly is:
Terpolymer EP rubber: 90～110 carbon blacks: 65～75
Paraffin hydrocarbon ils: 30～40 indirect process zinc oxides: 4～6

Anti-aging agent RD: 1.5 Triple Pressed Stearic Acid: 1.0
Mo Deli 935P:1.5 silane coupling agent: 1.5
Sulphur: 0.7 compound accelerant EM-33:1.8.
The ME of car steering tube column steering shaft rubber seal shade assembly:
(1) requires to take by weighing formula material according to the synthetic rubber technique prescription, then through the Banbury mixer viton;
(2) will detect qualified viton through the mill bar of stopping, it will be injected in the mould in the vulcanizing equipment, pressurization 170～190Kgf/cm
2, being warming up to 165 ℃～175 ℃, 350～380 seconds time was carried out sulfidizing.
(3) product of then above-mentioned sulfidizing being crossed carries out deburring, check, warehouse-in.
Beneficial effect of the present invention:
The car steering tube column steering shaft rubber seal shade assembly that the inventive method makes; It is little etc. to have good tensile strength at yield, tensile yield, tear strength, rebound resilience, anti-ozone, anti-pollution and cementability, smell, thereby has guaranteed its good sealing property and stability.Improved technical features such as tensile strength at yield, tensile yield, tear strength, rebound resilience, anti-pollution and cementability, the smell of product is little, broken France in this art monopoly position.
