Abstract

The invention relates to a preparation method of a surface treatment agent for PVC plastic soles. The method of the invention firstly prepares chlorinated polyethylene and methyl methacrylate copolymer, and then prepares chlorinated polyethylene and methyl methacrylate copolymer and perchloroethylene resin, toluene, ethyl acetate, 5-cyclohexanone, butyl Ketone, acetone and anti-aging agent 264 are added into the reaction kettle, and stirred for 2 to 4 hours under the condition of 50 to 80 DEG C to obtain the finished product of the surface treatment agent for PVC plastic soles. The specific method for preparing the chlorinated polyethylene and methyl methacrylate copolymer is to mix and stir toluene, ethyl acetate, methyl ethyl ketone, acetone, methyl methacrylate and chlorinated polyethylene to fully dissolve the chlorinated polyethylene , filled with nitrogen and heated to 70-90° C., then added benzoyl peroxide, and the reaction was performed at a constant temperature for 3-6 hours and then lowered to normal temperature. The surface treatment agent prepared by the method of the invention has good treatment effect and can meet the bonding requirements of the shoe industry.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to a preparation method of a surface treatment agent, in particular to a preparation method of a surface treatment agent for PVC plastic soles used in combination with shoe adhesives in cold-bonded shoemaking. Background technique [0002] PVC (polyvinyl chloride) plastic sole material has advantages such as strength is big, wear-resisting, attractive in appearance and economy, therefore, PVC plastic is widely used in sole material. In the cold-bonded shoemaking industry, in order to improve the bonding strength, it is often necessary to carry out surface treatment on the bonding material. The surface treatment method is generally grinding with a grinding wheel to make it have a rough surface, or using a surface treatment agent to change the surface state of the sole material, or both at the same time to achieve a good bonding effect. Unlike rubber sole materials, PVC plastic sole ...
