Embodiment 1

[0022] A high temperature resistant chloroprene rubber, prepared from the following raw materials in parts by weight: 100 parts of chloroprene rubber, 5 parts of magnesium oxide, 0.4 part of stearic acid, 5 parts of zinc oxide, 2 parts of vulcanization retarder, trioxide 0.35 parts of lead, 2 parts of octylated diphenylamine, and 2 parts of phosphate ester.

[0023] The preparation steps are as follows:

[0024] Put the natural rubber and carbon black into the open mill for kneading, add anti-aging agent, mix evenly, and prepare the mixture. The mixture is heat-treated for 7-12 minutes on a high-temperature hot roller at 120°C-160°C. Cool to room temperature, the cooling time is 9-11h, add magnesium oxide, stearic acid, zinc oxide, vulcanization retarder, trilead tetroxide, octylated diphenylamine, phosphate ester on the open mill at room temperature to make rubber.

Embodiment 2

[0026] A high-temperature-resistant chloroprene rubber, prepared from the following raw materials in parts by weight: 100 parts of chloroprene rubber, 4 parts of magnesium oxide, 0.3 parts of stearic acid, 4 parts of zinc oxide, 1 part of vulcanization retarder, trioxide 0.34 parts of lead, 1 part of octylated diphenylamine, and 1 part of phosphate ester.

[0027] According to the same method as in Example 1, high temperature resistant chloroprene rubber was prepared.

Embodiment 3

[0029] A high temperature resistant chloroprene rubber, prepared from the following raw materials in parts by weight: 100 parts of chloroprene rubber, 5 parts of magnesium oxide, 0.5 part of stearic acid, 6 parts of zinc oxide, 3 parts of vulcanization retarder, trioxide 0.36 parts of lead, 3 parts of octylated diphenylamine, and 3 parts of phosphoric acid ester.

[0030] According to the same method as in Example 1, high temperature resistant chloroprene rubber was prepared.

Abstract

The invention belongs to the technical field of rubber materials and relates to high temperature resistant chloroprene rubber and a preparation method thereof. The high temperature resistant chloroprene rubber is prepared from the following raw materials in parts by weight: 80 to 120 parts of chloroprene rubber, 4-6 parts of magnesium oxide, 0.3-0.7 part of stearic acid, 3-6 parts of a vulcanizingagent, 1-3 parts of a vulcanization retarder, 0.3-0.4 part of an accelerant, 1-3 parts of an antioxidant and 1-3 parts of a plasticizer. The high temperature resistant chloroprene rubber is physically stable, can maintain the physical properties unchanged in harsh environment, is especially good in high temperature resistance, and is suitable for use in high temperature environment.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and relates to a high-temperature-resistant chloroprene rubber and a preparation method thereof. Background technique [0002] Neoprene is generally used in the production of auto parts, machinery and industrial products and adhesives, and is also used in construction, coated fabrics, wires / cables, etc., but the market in Western Europe and North America is gradually shrinking. Secondly, due to the relatively high price of neoprene and the increase in temperature under the hood, neoprene is gradually being replaced by other rubber types. The overall performance of neoprene rubber is good, which is unmatched by natural rubber and other synthetic rubbers. Neoprene rubber has been widely used in the fields of transportation, construction, light industry and military industry in various countries. [0003] In my country, the consumption of chloroprene rubber for shoemaking and construction ...
