Abstract

The invention relates to a plastic-rubber high molecular composite synthetic resin adhesive which comprises the following components: para-tertiary butyl phenol-formaldehyde resin, chloroprene rubber, magnesium oxide, C5/C9 copolymerized petroleum resin, BTH (butylated hydroxytoluene) antioxidant, methyl acetate (refined), ethyl acetate, dichloropropane, methylbenzene and 120#solvent oil. On the basis of giving a full play to the advantages of the phenol-formaldehyde synthetic resin, the magnesium oxide is added and the chloroprene rubber linear high molecular material and the C5/C9 copolymerized petroleum resin having high adhesion property and good heat resistance are introduced to perform grafting, chelation and other high molecular reactions on the molecular structure so as to form a copolymer with the phenol-formaldehyde resin, thus obtaining the plastic-rubber high molecular composite high-performance synthetic resin adhesive having multiple comprehensive performances. The plastic-rubber high molecular composite synthetic resin adhesive has high bonding strength and good water resistance, heat resistance and chemical stability, and has the composite high performances of a plastic-rubber high molecular elastomer such as pliability, flexibility and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives in fine chemical industry, in particular to a plastic-rubber polymer composite synthetic resin adhesive. Background technique [0002] Traditional phenolic resin adhesives have the advantages of high bonding strength, water resistance, heat resistance and good chemical stability, but they have low wear resistance, high cost, high internal pressure, easy surface cracking, high hot pressing temperature and long pressure resistance time And other shortcomings, so that it is subject to many restrictions in use. It is inevitable to modify and optimize the traditional phenolic resin adhesive. Contents of the invention [0003] The object of the present invention is to provide a plastic-rubber polymer composite high-performance synthetic resin adhesive that can fully utilize the advantages of the phenolic resin adhesive and overcome its shortcomings. [0004] In the present invention, its batching ...
