preparation example Construction

[0026] This embodiment discloses a method for preparing a chemically resistant outsole rubber compound for labor insurance shoes according to claim 1, comprising the following steps:

[0027] (1) Preparation of peptizer masterbatch: get No. 3 imported cigarette sheet rubber and peptizer in the same weight portion as the peptizer and mix to make peptizer masterbatch;

[0028] (2) glue breaking: after neoprene rubber, EPDM rubber and remaining No. 3 imported smoke sheet glue are cut into small pieces by weight, they are respectively dropped into glue breaking machine and broken into rubber threads;

[0029](3) Mastication: Put the No. 3 imported tobacco sheet rubber filament into the open mill with a roller distance of 0.5mm or less and a roller temperature of 40°C to 50°C by using the Botong plasticating method. After plasticizing and thinning, Discharging and cooling, put the cooled rubber material into the open mill with a roll distance of 5mm~8mm, and add roller mastication,...

Embodiment 1

[0034] The labor insurance shoes of the present embodiment are chemically resistant outsole rubber mixes, and the rubber mix raw materials include the following components by weight: 65 parts of No. 3 imported smoked sheet rubber, 35 parts of chloroprene rubber, and 15 parts of EPDM rubber. 7 parts of coumarone resin, 10 parts of petroleum resin, 4 parts of stearic acid, 4 parts of nano zinc oxide, 2.5 parts of magnesium oxide, 1.5 parts of sulfur, 0.8 parts of accelerator Na-22, 1.2 parts of accelerator TBSI, 1.2 parts of anti-aging agent NBC, 2.4 parts of anti-aging agent RD, 23 parts of modified sepiolite powder, and 1 part of peptizer.

Abstract

The invention provides a chemical corrosion-resistant outsole rubber compound for safety shoes. The rubber compound comprises the following raw materials in parts by weight: 62-68 parts of #3 imported smoke sheet rubber, 32-38 parts of chloroprene rubber, 12-16 parts of ethylene-propylene-diene-terpolymer rubber, 6-8 parts of coumarone resin, 8-12 parts of petroleum resin, 3-6 parts of stearic acid, 3-5 parts of nano zinc oxide, 3-4 parts of magnesium oxide, 1-2 parts of sulfur, 1.2-2.5 parts of an accelerant, 3-4.5 parts of an antiageing agent, 20-25 parts of modified sepiolite powder and 0.8-1.2 parts of a peptizer. The #3 imported smoke sheet rubber serving as a primary component has a good chemical reagent resistant property, and chloroprene rubber has good acid and alkali resistant properties and chemical reagent resistant property. By taking the #3 imported smoke sheet rubber and chloroprene rubber as the primary component, and adding the modified sepiolite powder and ethylene-propylene-diene-terpolymer rubber which are excellent in acid and alkali resistance and chemical corrosion resistance, the chemical corrosion resistance of the rubber compound can be further enhanced under the synergistic effect of the components.

Description

technical field [0001] The invention relates to a mixed rubber, in particular to a chemical corrosion-resistant outsole mixed rubber for labor insurance shoes and a preparation method thereof. Background technique [0002] With the development of economy and society, the safety and labor protection awareness and protection strength of national and enterprise managers and on-site workers have increased unprecedentedly; and due to the particularity of chemical, pharmaceutical and other industries, personnel working in these industries It is often necessary to be exposed to a lot of chemical reagents. In order to ensure safety, workers in these industries are required to wear labor protection equipment that meets the requirements of the working environment, and labor insurance shoes are necessary protective equipment. The production of labor insurance shoes that meet the requirements requires not only ordinary wearing functions, but also strict requirements for acid and alkali ...
