Abstract

The invention relates to an EPDM sulfur-free rubber for an automobile lamp seal housing and a preparation method thereof. The EPDM sulfur-free rubber comprises the following raw materials in parts by weight: 100 parts of EPDM raw rubber, 4-7 parts of zinc oxide, 1-2 parts of stearic acid, 70-100 parts of carbon black, 30-50 parts of filler, 30-40 parts of softening oil, 1-3 parts of activator, 3-5 parts of peroxide vulcanizing agent and 1-2 parts of vulcanization aid. The preparation method comprises the steps of firstly mixing the EPDM, zinc oxide, stearic acid, carbon black, the filler, the softening oil and the activator uniformly, then adding the peroxide vulcanizing agent and vulcanization aid and then mixing uniformly. The EPDM sulfur-free rubber for the automobile lamp seal housing has the advantages that the pollution of free sulfur to the automobile lamp system and the occurrence of fogging in the automobile lamp during the running of the automobile can be prevented.

Description

A kind of car light seal closure uses EPDM without sulphur glue and preparation method thereof
Technical field
The present invention relates to a kind of rubber product, specifically, is that a kind of car light seal closure EPDM is without sulphur glue.
Background technology
Require free sulphur content to be less than 0.01% for automobile lamp with seal closure vulcanized rubber, main purpose is in car light, to haze and affect car light function in the pollution of free sulphur on lamp system and automobile driving process in order to prevent.
Chinese patent literature CN201210443237.8, discloses a kind of car light sealing hot-melt adhesive composition and preparation method thereof.But about preventing that free sulphur from sealing and using without sulphur glue the car light of lamp system pollution, yet there are no report.
Summary of the invention
The object of the invention is for deficiency of the prior art, provide a kind of car light seal closure EPDM without sulphur glue.
One object more of the present invention is that the preparation method of a kind of car light seal closure EPDM without sulphur glue is provided.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of car light seal closure uses EPDM without sulphur glue, described EPDM comprises 100 parts of EPDM rubbers without the material composition of sulphur glue in weight part, 4～7 parts, zinc oxide, 1～2 part of stearic acid, 70～100 parts of carbon blacks, 30～50 parts of weighting agents, 30～40 parts of softening oils, 1～3 part of promoting agent, 3～5 parts of peroxide vulcanizing agents, 1～2 part of vulcanization aid.
Described EPDM is that the 3rd monomer is ENB type and the higher ethylene-propylene diene copolymer of content, and it is that main, described softening oil adopts the higher paraffin oil of flash-point that described carbon black adopts N990.
For realizing above-mentioned second object, the technical scheme that the present invention takes is:
First by EPDM, zinc oxide, stearic acid, carbon black, weighting agent, softening oil, promoting agent is mixing adds peroxide vulcanizing agent after evenly, vulcanization aid more mixing evenly.One step cure condition: 175 DEG C of temperature, 10 minutes time, pressure 15～18MPa, post vulcanization condition: 150 DEG C of temperature, 1～1.5 hour time.
The invention has the advantages that:
1, the present invention can prevent from car light, hazing in the pollution of free sulphur to lamp system and vehicle traveling process.
