Embodiment 1

[0019] The invention discloses a shock-absorbing foam rubber, which comprises the following raw materials measured in parts by mass:

[0020]

[0021] The preparation method of described shock-absorbing foam rubber is:

[0022] Step 1. Mix natural rubber, light calcium carbonate, stearic acid, urea, carbon black, and paraffin oil evenly, put them into an open mill for mastication, then add foaming agent, anti-aging agent, accelerator, and finally add vulcanizing agent , to prepare the rubber compound, the distance between the rollers for masticating is 0.5cm, and the masticating temperature is 40°C;

[0023] Step 2: Put the silicone rubber into the open mixer for masticating, and after the silicone rubber is softened, add the rubber compound prepared in step 1 for plasticizing until the silicone rubber and the rubber compound prepared in step 1 are evenly mixed, and then release the sheet , to obtain the secondary compound rubber, the distance between the rollers for masti...

Embodiment 2

[0027] The invention discloses a shock-absorbing foam rubber, which comprises the following raw materials measured in parts by mass:

[0028]

[0029] The preparation method of described shock-absorbing foam rubber is:

[0030] Step 1. Mix natural rubber, light calcium carbonate, stearic acid, urea, carbon black, and paraffin oil evenly, put them into an open mill for mastication, then add foaming agent, anti-aging agent, accelerator, and finally add vulcanizing agent , to prepare the compounded rubber, the distance between the rollers for masticating is 1cm, and the masticating temperature is 50°C;

Abstract

The invention discloses shock-absorption foamed rubber, which comprises the following raw materials in parts by mass: 30 to 45 parts of silicone rubber, 35 to 60 parts of natural rubber, 5 to 10 parts of stearic acid, 5 to 10 parts of foaming agents, 3 to 8 parts of anti-aging agents, 1 to 3 parts of accelerants, 3 to 5 parts of vulcanizing agents, 1 to 2 parts of carbamide, 3 to 8 parts of light calcium carbonate, 3 to 5 parts of black carbon, and 1 to 3 parts of paraffin oil. The shock-absorption foamed rubber is low in density, light in weight, large in specific area, high in mechanical property and good in damping property, meanwhile, is excellent in shock absorption effect, and good in noise reduction effect, and is a novel engineering material which is good in physical and mechanical properties and high in cost performance.

Description

technical field [0001] The invention relates to a rubber, in particular to a shock-absorbing foam rubber. Background technique [0002] With the requirements of scientific and technological progress, at present, insulating rubber not only requires high insulation performance, but also has low density, light weight, good damping performance, strong mechanical properties and good heat aging resistance. Therefore, traditional rubber products simply have good insulation properties, which are far from meeting the requirements of modern society. Contents of the invention [0003] Purpose of the invention: the present invention solves the above problems and provides a shock-absorbing foam rubber. [0004] Technical solution: a shock-absorbing foam rubber, including the following raw materials measured by mass fraction: [0005] [0006] The preparation method of described shock-absorbing foam rubber is: [0007] Step 1. Mix natural rubber, light calcium carbonate, stearic a...
