preparation example Construction

[0018] The preparation method of the composite rubber material of the present invention adopts a reverse mixing method and includes the following steps:

[0019] Step 1. Firstly, MgO, 2, 2'-dithiodibenzothiazole, N,N,-m-phenylene bismaleimide, N,N-dibutyldithiocarbamate nickel, high Disperse white carbon black, nano-magnesium hydroxide, antimony trioxide, γ-glycidoxypropyltrimethoxysilane and petrolatum are added to the internal mixer, mixed for 2 minutes, and then the chlorosulfonated polyethylene and ethylene -Vinyl acetate rubber (EVM) and hydrogenated nitrile rubber (HNBR) are also put into the internal mixer and mixed for 5 minutes. Finally, the plasticizer is put into the internal mixer and mixed for 5 minutes from the internal mixer. Unload the material and mix on an open mill for 5 minutes, and then cool down.

[0020] Step 2. Put the rubber compound obtained in step 1 into the internal mixer again, and add PbO and bis-pentamethylene thiuram hexasulfide for mixing. When th...

Abstract

The invention relates to a manufacture method of a composite rubber material. The manufacture method comprises the following steps: adding MgO, 2,2'-dithio-dibenzo thiazole, N, N,-phenylenedimaleimide, N, N-nickel dibutyl dithiocarbamate, high-dispersion white carbon black, nano-magnesium hydroxide, antimonous oxide, gamma-glycidoxy propyl trimethoxy silane and vaseline to an internal mixer; mixing for 2 to 3 minutes; then adding chlorosulfonated polyethylene, ethylene-vinyl acetate copolymer (EVM) and hydrogenated butadiene-acrylonitrile rubber (HNBR) to the internal mixer; mixing for 4 to 5 minutes; finally adding a plasticizer to the internal mixer; mixing for 4 to 5 minutes; discharging materials from the internal mixer; mixing for 4 to 6 minutes through an open mill; forming pieces and discharging; cooling to obtain a rubber compound; adding the rubber compound obtained in step 1 to the internal mixer again; adding PbO and dipentamethylenethiuram hexasulfide to mix; discharging after the rubber is at temperature of 95 DEG C; mixing through the open mill for 4 to 5 minutes; forming pieces through a calendar; and cooling to obtain the composite rubber material.

Description

Technical field [0001] The invention relates to a manufacturing method of a composite rubber material. Background technique [0002] Wind energy The kinetic energy generated by the movement of large amounts of air on the surface of the earth. Due to the different temperature changes and the different water vapor content in the air after different parts of the ground are irradiated by the sun, the difference in air pressure is caused. In the horizontal direction, high-pressure air flows to low-pressure areas, that is, wind is formed. Wind energy resources are determined by the density of wind energy and the accumulated hours of wind energy available per year. Wind energy density is the wind power available per unit windward area, and is proportional to the power of the wind speed and the air density. [0003] Due to the shortage of resources such as oil and coal at home and abroad, countries are vigorously developing new energy sources. As a clean energy, wind energy has an inexha...
