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 through composite grafting, and relates to a surface treatment agent. The raw material components of the treatment agent mainly include styrene-butadiene rubber, nitrile rubber, neoprene, acetone, butanone, methylcyclohexane, ethyl acetate, dimethyl carbonate, 120#, methyl methacrylate, tripropylene glycol Diacrylates, Dibenzoyl Peroxide and Terminators. The preparation method mainly includes mixing and stirring methyl ethyl ketone and methylcyclohexane, etc., then adding styrene-butadiene rubber and dibenzoyl peroxide, etc., then adding methyl methacrylate dropwise for reaction, and then adding tripropylene glycol diacrylic acid Ester and dibenzoyl peroxide, after cooling down, add terminator and 120# and stir to obtain TPR treatment agent. The preparation method adopts the method of composite grafting of active monomers and reacts with a weak solvent, and the obtained treating agent-treated TPR shoe material has the performance of hydrolysis resistance and aging resistance under the condition of ensuring the bonding performance.

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...
