Abstract

The invention relates to the field of rubber, and specifically relates to technology for processing a pre-sulphurized butyl rubber plate. The technology comprises the following steps: a first step, plastication: a butyl rubber raw material 1675N and a butyl rubber raw material 268 are placed in an open mill for plastication; a second step, the butyl rubber raw material which is plasticated in thefirst step, active magnesium oxide, stearic acid, chlorinated paraffin, polyethylene wax, an anti-aging agent RD, an anti-aging agent WB-16, carbon black 770, carbon black 660, talcum powder, barium sulfate, aromatic hydrocarbon oil, paraffin oil 300#, transformer oil, benzofuran, and zinc oxide are placed together for kneading; a step 3, the raw materials in the step 2, sulphur, a promoter DM, apromoter ZDC, and a promoter NA-22 are placed in an open mill together for open mill; a step 4, a rubber sheet after open mill is placed in a calendar, and is compacted into the butyl rubber plate bya belt conveyer; a step 5, the butyl rubber plate after moulding by the calender and the belt conveyer is placed in a steam vulcanizer for vulcanization. Finally, the pre-sulphurized butyl rubber plate has the advantages of high wear resistance, high corrosion prevention, and long usage life.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a process for processing prevulcanized butyl rubber sheets. Background technique [0002] At present, the existing domestic natural rubber-lined steel pipes and butyl rubber-lined steel pipes can meet the requirements of limestone and gypsum slurry working conditions, but when special working conditions require on-site rubber lining or on-site repairs are required after rubber-lined pipelines are damaged during operation, natural Rubber and butyl rubber cannot meet such defects. Therefore, the present inventor made further research on this, and developed a pre-vulcanized butyl rubber sheet processing technology, and this case arose from it. Contents of the invention [0003] The purpose of the present invention is to provide a pre-vulcanized butyl rubber sheet processing technology, which has the advantages of high wear resistance, high corrosion resistance and long service life.
