Embodiment 1

[0021] The concrete production steps of embodiment 1 are as follows:

[0022] Compound production

[0023] (1) Weigh various ingredients according to the specific formula ratio, and the rubber raw material component is the ratio by weight. The rubber raw material component of Example 1 is the weight ratio: 120 parts of 1# natural rubber, 2 parts of sulfur, 4 parts of zinc oxide, 2 parts of stearic acid, 1 part of paraffin, 10 parts of pine tar, 80 parts of spray carbon black, 20 parts of channel black, accelerator DM (Chinese name: 2,2'-dithiodibenzothiazole, molecular formula: C 14 h 8 N 2 S 4 ) 1 part, antioxidant D (Chinese name: N-phenyl-2-naphthylamine, molecular formula: C 16 h 13 N) 1 part. The weight unit of each part in the component is determined according to production needs, such as 1 kilogram per part.

[0024] (2) According to the ratio of rubber raw materials in step 1), add 1 # Add natural rubber to the rubber mixing machine. After mixing for 2 minutes...

Embodiment 2

[0032] The production process of embodiment 2 is identical with embodiment 1, and difference is that the rubber material component ratio is different, and the rubber material composition of embodiment 2 is as follows by weight component: 1 # 135 parts of natural rubber, 2.5 parts of sulfur, 5 parts of zinc oxide, 3 parts of stearic acid, 1.1 parts of paraffin, 11 parts of pine tar, 90 parts of spray carbon black, 30 parts of channel black, accelerator DM (Chinese name: 2 , 2'-dithiodibenzothiazole, molecular formula: C14H8N2S4) 1.1 parts, anti-aging agent D (Chinese name: N-phenyl-2-naphthylamine, molecular formula: C16H13N) 1.1 parts.

Embodiment 3

[0033] The production process of embodiment 3 is identical with embodiment 1, and difference is that rubber material component ratio is different, and the rubber material composition of embodiment 3 is as follows by weight component: 1 # 150 parts of natural rubber, 3 parts of sulfur, 6 parts of zinc oxide, 4 parts of stearic acid, 1.2 parts of paraffin, 12 parts of pine tar, 100 parts of spray carbon black, 40 parts of channel black, accelerator DM (Chinese name: 2 ,2'-dithiodibenzothiazole, molecular formula: C 14 h 8 N 2 S 4 ) 1.2 parts, anti-aging agent D (Chinese name: N-phenyl-2-naphthylamine, molecular formula: C 16 h 13 N) 1.2 parts.

Abstract

The invention relates to a sizing material of a high hardness rubber seal. The sizing material comprises the raw material components in parts by weight as follows: 120-150 parts of 1# natural rubber, 2-3 parts of sulphur, 4-6 parts of zinc oxide, 2-4 parts of stearic acid, 1-1.2 parts of paraffin, 10-12 parts of pine tar, 80-100 parts of spraying carbon black, 1-1.2 parts of an accelerant DM (Chinese name: 2,2'-dithio di-benthothiazole, molecular formula: C14H8N2S4), and 1-1.2 parts of an antiager D (Chinese name: N-phenyl-2-naphthylamine, molecular formula: C16H13N). According to the invention, high hardness components are added in the rubber formula, and meanwhile the vulcanizing efficiency is enhanced, and the integral hardness of rubber is improved.

Description

technical field [0001] The invention relates to the field of rubber, in particular to high-hardness rubber sealing material. Background technique [0002] Due to the increasingly diversified functions of modern mechanical equipment, more and more additional components are added to the equipment, resulting in heavier equipment weight and higher requirements for the hardness of the rubber components. Due to the low hardness of most equipment rubber parts, it is easy to deform during use and affect the normal operation of the equipment. Contents of the invention [0003] The purpose of the present invention is to provide a high-hardness rubber sealing compound that can improve the hardness of rubber parts and meet the requirements of use. [0004] The technical solution of the present invention is: high-hardness rubber seal compound, which is characterized in that its rubber raw material components and raw material weight ratio are 1 # 120-150 parts of natural rubber, 2-3 p...
