Abstract

The invention discloses a red butyl rubber mixing technology. The technology includes the following steps that firstly, raw rubber plastifying is conducted, then a filler, titanium dioxide, a softener and an accelerator are added, and press fit internal mixing is conducted for three minutes; secondly, half of clay and a red pigment are added again, and press fit internal mixing is conducted for three minutes; thirdly, the other half of clay is added, and press fit internal mixing is conducted for four minutes; and finally rubber materials are discharged, and a vulcanizing agent is added to an open mill. By means of the red butyl rubber mixing technology, the problem that the color mixing effect of the red pigment is not obvious due to the fact that the filler adsorbs the red pigment can be solved; the color mixing effect of the pigment is improved, the quality of mixed rubber is improved, product performance is stabilized, the appearance property of vulcanizate is improved, and the actual production requirements are met.

Description

technical field [0001] The patent of the invention belongs to the technical field of rubber and relates to a mixing process method, in particular to a mixing process method of red butyl rubber. Background technique [0002] At present, the rubber compounds produced by most domestic rubber manufacturers are gray or black, and there are few colored rubber compounds. However, the foreign market still needs colored butyl rubber products. [0003] The patent document with the notification number CN104530507A discloses a method for mixing low-hardness nitrile rubber. The principle of this method is similar to that of this patent, that is, to control the rubber discharge temperature of the internal mixing, but this method does not disclose the influence of the feeding sequence on the rubber compound. [0004] When red butyl rubber is mixed, it generally adopts the following method: raw rubber mastication - input of filler and red pigment - input of small materials - discharge of r...
