Embodiment

[0014] A preparation method of acrylonitrile-butadiene rubber metal composite board, the raw material of described recycling process comprises acrylonitrile-butadiene rubber, zinc oxide, stearic acid, sublimated sulfur, carbon black, dibutyl phthalate, butyl acetate, bentonite , Kemlock and cetyltrimethylammonium bromide, the preparation method comprises the steps: (1) pulverize, get a 1000ml beaker, take by weighing 100g nitrile rubber on an electronic balance, after being cut into fritters Put it into a high-speed universal grinder for crushing. (2) Stir to dissolve, then dissolve with 500ml butyl acetate, perform electric stirring during the dissolution process, the rotating speed is 70r / min, and the masterbatch is uniform after stirring for several hours. (3) Add foaming agent, then add zinc oxide, stearic acid, dibutyl phthalate, vulcanizing agent and carbon black (8000 mesh) in sequence, and then add foaming agent after the powder is basically added. Dissolve and disper...

Abstract

The invention discloses a preparation method of a nitrile rubber composite metal plate. Raw materials of a recovery processing technology comprise nitrile rubber, zinc oxide, stearic acid, sublimated sulfur, carbon black, dibutyl phthalate, butyl acetate, bentonite, Chemlok and hexadecyl trimethyl ammonium bromide. The preparation method comprises the following steps: (1) crushing the nitrile rubber, wherein a beaker of 1000ml is taken out, 100g of the nitrile rubber is weighed on an electronic balance, the weighed nitrile rubber is cut into small blocks, and the small blocks are put into a high-speed universal crusher to be crushed; (2) stirring and dissolving the nitrile rubber, dissolving the nitrile rubber with 500ml of butyl acetate, electrically stirring the dissolved nitrile rubber at the rotational speed of 70r / min in the process of dissolving, and stirring the nitrile rubber for several hours until masterbatch is uniform.

Description

technical field [0001] The invention relates to the technical field of rubber and plastics, in particular to a method for preparing a nitrile rubber metal composite board. Background technique [0002] In recent years, my country's economic level has continued to improve, and the automobile production industry has also developed rapidly. Due to the increase in production, the manufacture of automobile sealing plates related to automobile production has also attracted people's attention. , low-life products, after 20 years of pioneering and enterprising through the introduction of foreign technology, joint ventures and cooperation methods, and technological improvements, our sealing plate manufacturing has finally taken shape, which can meet the needs of the domestic automobile industry for sealing plates. [0003] Although my country has made great progress in the research and development of rubber-metal composite panels in recent years, there is still a big gap compared with...
