Abstract

The invention discloses an environment-friendly adhesive for metal hoses and rubber hoses as well as a preparation method of the adhesive. The adhesive is prepared from components in parts by weight as follows: 17-34 parts of a chlorosulfonated polymer, 11-30 parts of polyvinyl alcohol, 8-22 parts of phenolic resin, 11-27 parts of isocyanate, 12-38 parts of montmorillonite, 7-16 parts of titanium dioxide, 8-14 parts of copper oxide, 7-12 parts of ferric sulfate and 11-20 parts of borax. (1) No additives containing toxic elements are added to the environment-friendly adhesive for the metal hoses and the rubber hoses, and no toxic substances are produced during usage; (2) the environment-friendly adhesive for the metal hoses and the rubber hoses has good heat resistance.

Description

technical field [0001] The invention belongs to the field of material chemistry and relates to an adhesive, in particular to an environment-friendly metal hose and rubber hose adhesive and a preparation method thereof. Background technique [0002] The bonding between rubber and metal has a long history, which can be traced back to 1850. The bonding methods currently used can be divided into direct bonding method, hard rubber method, brass crossing method and adhesive bonding method. . Among them, the adhesive method is currently the most widely used and effective method. Phenolic resins, polyisocyanates and halogenated polymers are the three main types of matrix materials commonly used in adhesives. [0003] Phenolic resins are mainly used for polar rubber, and can also be used as an undercoat material for bonding non-polar rubber. Isocyanate often refers to triphenylmethane triisocyanate. This adhesive is suitable for the bonding of polar rubber and non-polar rubber suc...
