preparation example Construction

[0023] The invention also discloses an outsole compound rubber for insulating industrial and mining rubber boots and a preparation method thereof, comprising the following steps:

[0024] a. Glue breaking: Break the No. 2 standard rubber on the rubber breaking machine according to the set weight, put the butadiene rubber into the rubber after the standard rubber is softened and roll it, and mix it initially to make a film;

[0025] b. Mastication: Throw the produced film into an open mill with a roll distance of less than 0.5mm and a roll temperature of 40°C to 50°C by thin pass plastication method. The cooled rubber material is put into the open mill with a roller distance of 5mm-8mm, covered with rollers and plasticized, and C.S.R rubber is added in parts by weight, and processed to obtain a blended film, and then the blended film is put into the roller pitch Plasticize the thin pass again in the open mixer with a thickness of less than 0.5mm, and finally put the rubber comp...

Abstract

The invention discloses a rubber compound for outsoles of insulated industrial rubber boots. The rubber compound comprises components in parts by weight as follows: NO.2 standard rubber, butadiene rubber, C.S.R rubber, insoluble sulfur, stearic acid, activated zinc oxide, an accelerant, an anti-ageing agent, white carbon black, a Si69 silane coupling agent, a white carbon black dispersing agent, solid coumarone resin, high-wearability carbon black, pine tar and engine oil. The rubber compound for the outsoles of the insulated industrial rubber boots has excellent insulating property, all that is needed is to shape an outsole rubber piece, an insulating layer is not required to be added, the process is simple, the number of workers required for each piece production line is reduced by more than six, and the rubber compound has the characteristics of small punching shrinkage, small deformation during storage of rubber pieces, good stickiness, light weight, good wear resistance and the like.

Description

technical field [0001] The invention relates to a rubber compound, in particular to a rubber compound for the outsole of insulating industrial and mining rubber boots and a preparation method thereof. Background technique [0002] In recent years, with the progress of society and the improvement of protection requirements for mine workers, the ordinary industrial and mining rubber boots worn by miners have been gradually reduced, and such as insulating rubber boots, anti-smashing rubber boots, anti-puncture rubber boots or composite rubber boots with the above functions It is gradually increasing, and the state has also issued relevant industry standards in order to enable mine workers to get better labor protection. Insulated industrial and mining rubber boots that are widely used at present, most of the manufacturers adopt the method of adding an insulating layer between the wear-resistant outsole (basically non-insulated rubber) and the sponge midsole, and there are very ...
