Abstract
The invention discloses a production process of a rubber sealing strip. The production process is characterized by comprising: a first step of blending materials, namely, a step of mixing raw materials including silicone rubber, white carbon black, paraffin oil and a sulfurizing agent according to a weight ratio of 7:1:2:1; a second step of smashing, namely, a step of mixing fluororubber, the white carbon black, a promoter and the sulfurizing agent, adding the mixture into a smasher and smashing; a third step of putting the mixture into a mould and extruding to prepare a strip-shaped semi-finished product, with the pressure being 800-1000 MPa; a fourth step of sulfurizing, namely, a step of sulfurizing the semi-finished product in a sulfurizing tank; and a fifth step of cleaning the sulfurized semi-finished product, airing, and burring. The rubber sealing strip has good ageing resistance and sealing effects.
Description
Technical field
The present invention relates to a kind of production technique, relate in particular to a kind of production technique of rubber weather strip.
Background technology
Rubber weather strip is the sealed strip being formed by rubber production.Be mainly used in the fields such as automobile, machinery, door and window, play the effects such as dustproof, insect protected, waterproof, fixing, sound insulation, damping, sealing.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of easy to make, simple to operate, ageing-resistant a kind of new type rubber sealed strip production technique.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of production technique of rubber weather strip, it is characterized in that: comprise following production stage: the first step: batching, the ratio that it is 7:1:2:1 according to weight ratio that described batching refers to raw silicon rubber, white carbon black, paraffin oil, vulcanizing agent mixes; Second step: pulverize, described pulverizing refers to described Fluoride for Raw Material rubber, white carbon black, promotor, vulcanizing agent are mixed, is placed in equipment and pulverizes; The 3rd step: described mixture is placed on to extruding in mould and forms strip work in-process, described pressure is 800MPa-1000MPa; The 4th step: sulfidizing, described sulfidizing refers to work in-process is placed in vulcanizing boiler and is vulcanized; The 5th step: clean sulfuration after work in-process, dry, deburring.
Described pressure is 900 MPa.
Compared with prior art, beneficial effect of the present invention is:
Because the present invention has adopted rational processing condition, so can produce the good sealed strip of ageing-resistant sealing effectiveness.
Embodiment
