Abstract

The invention discloses a water-based rubber treating agent. The water-based rubber treating agent is prepared from raw materials in parts by weight as follows: 3-5 parts of nano-silica, 80-100 partsof methyl methacrylate, 10-15 parts of rosin, 3-5 parts of polyethylenimine, 4-7 parts of oleic acid, 0.3-1 part of 2-mercapto-benzimidazole, 20-30 parts of a rubber matrix, 2-4 parts of ammonium persulfate and 0.7-1 part of a dispersant. The treating agent improves a traditional organic solvent treatment method and is high in safety and environmental protection property and good in effect.

Description

technical field [0001] The invention belongs to the field of leather, in particular to a water-based rubber treatment agent. Background technique [0002] Rubber is a sole material widely used in the footwear industry. It needs to be pretreated to overcome the influence of material differences and meet the objective requirements for sole bonding. The traditional shoemaking industry uses the cold bonding process to increase the specific surface area of ​​the rubber by removing the weak interface layer on the rubber surface and increasing the roughness, thereby increasing the contact area. There are two traditional surface treatment methods, one is to increase the surface roughness by mechanical grinding, the other is to use acetone and other solvents to wipe the surface after mechanical grinding, and the surface-treated rubber can be bonded by gluing. [0003] The existing technology is mainly to increase the degree of roughness to achieve the effect of increasing the specif...
