Abstract

The invention aims at providing a building-solvent-resistant sealing plug chloroprene rubber formula which is prepared through using DCR-66 chloroprene rubber, adding N770 carbon black, calcined kaolin and rapeseed oil and adding auxiliaries of zinc oxide, stearic acid, an anti-aging agent MB, an anti-aging agent ODA, magnesium oxide, an accelerant NA22, an accelerant TT, barium sulfide, softener chlorinated paraffin and a plasticizer diethyl azelate. Therefore, chloroprene rubber can meet the requirement that an industrial sealing dimethyl ether solvent is prevented from leaking.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a neoprene formula for construction solvent-resistant sealing plugs. Background technique [0002] Rubber is a highly elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. Neoprene is widely used in the field of sealing materials and the like. At present, fluorine rubber is mainly used for sealing dimethyl ether, which is relatively expensive. It is necessary to develop a rubber that can seal dimethyl ether well. Therefore, it is necessary to solve this problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a neoprene formula for building solvent-resistan...
