AI Technical Summary

Problems solved by technology

However, the prepared treatment agent also has disadvantages such as poor heat resistance and difficulty in rolling up.
[0007] In order to develop a non-toxic and environmentally friendly treatment agent with good treatment effect, R&D personnel have conducted a lot of research. Currently, the TPR treatment agent used on the market still has low adhesive strength, poor heat resistance, reflective marks and Therefore, it is urgent to provide a TPR treatment agent that is non-toxic and environmentally friendly, has weak reflective marks and high adhesive strength during treatment.

Abstract

The invention discloses an environment-friendly, high-performance, hydrolysis-resistant and aging-resistant TPR treatment agent prepared by composite grafting, and relates to a surface treatment agent. The treatment agent is mainly prepared from butadiene styrene rubber, butadiene-acrylonitrile rubber, chloroprene rubber, acetone, butanone, methylcyclohexane, ethyl acetate, dimethyl carbonate, 120#, methyl methacrylate, tripropylene glycol diacrylate, dibenzoyl peroxide and a terminating agent. A preparation method of the treatment agent mainly comprises the following steps: mixing and stirring the butanone, methyl cyclohexane and the like, adding the butadiene styrene rubber, dibenzoyl peroxide and the like, dropwise adding methyl methacrylate, performing a reaction, adding the tripropylene glycol diacrylate and dibenzoyl peroxide, cooling, adding the terminating agent, 120 # and the like, and stirring to obtain the TPR treatment agent. An active monomer composite grafting method isadopted, and a weak solvent is used for the reaction, so that the obtained treatment agent has hydrolysis resistance and aging resistance under the condition of ensuring the bonding performance when being used for treating TPR shoe materials.

Description

technical field [0001] The invention relates to a surface treatment agent, in particular to an environment-friendly high-performance hydrolysis-resistant and aging-resistant TPR treatment agent through composite grafting. Background technique [0002] According to statistics, my country is the world's largest footwear manufacturing base, accounting for 70% of the world's imports of footwear, and is the world's largest footwear exporter. A large amount of adhesives will be used in the manufacturing process of footwear. Most of the adhesives currently on the market use adhesives of toxic solvents (such as toluene, methylene chloride, halogenated substances, etc.), which seriously affect people's health and also It seriously pollutes the environment, so it is necessary to limit the content of harmful substances in adhesives to create a healthy living environment for producers and users. [0003] TPR shoe material is a non-polar material containing a lot of mineral oil. It cann...
