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 synthetic rubber field, be specifically related to a kind of car steering tube column steering shaft rubber seal shade assembly and manufacturing process thereof.
Background technology
As a vitals of car steering tube column and front coaming plate junction-Integral type steering shaft sealing cover assembly, motor turning, anxious accelerate and the moving process such as the road conditions of jolting in mainly play sealing and deadening, the noise that prevents engine enters cab by 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 whole manufacturing processed difficulty is larger, 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 the requirements such as low smell and environmental protection near cab.My company tackled key problems by 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
For 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 the manufacturing process thereof such as good rubber tensile strength at yield, tensile yield, tear strength, rebound resilience, anti-ozone, cementability, contaminative and smell are little.
The present invention is the technical scheme that its purpose of realization adopts: car steering tube column steering shaft rubber seal shade assembly adopts synthetic rubber, main raw material is: terpolymer EP rubber, carbon black, paraffinic hydrocarbon wet goods is characterized in that the component weight part of described 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 stearic acid: 1.0
Mo Deli 935P:1.5 silane coupling agent: 1.5
Sulphur: 0.7 compound accelerant EM-33:1.8.
The manufacturing process 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 by the Banbury mixer synthetic rubber;
(2) will detect qualified synthetic rubber by 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 stopping property and the stability that it is good.Improve the 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.
