Problems solved by technology

[0005] The residual amount of alkylphenol polyoxyethylene ether in alkylphenol polyoxyethylene ether (meth)acrylate is 2%-5%. On the one hand, alkylphenol polyoxyethylene ether is a non-UV component. It will migrate to the surface of the coating, causing environmental pollution; on the other hand, even if the amount of alkylphenol polyoxyethylene ether (meth)acrylate used in the coating is extremely low, it will also cause the residue of alkylphenol polyoxyethylene ether Far exceeds the limit of European regulations (the limit is 0.1%), so that the use of alkylphenol polyoxyethylene ether (meth)acrylate in coating formulations is greatly restricted

Abstract

The invention discloses a treatment method of alkylphenol polyoxyethylene ether (methyl) acrylate, an oligomer, a coating raw material, a coating and a preparation method, and belongs to the field of polymers. The treatment method comprises the following steps: mixing an alkylphenol polyoxyethylene ether (methyl) acrylate raw material and monoisocyanate with double bonds, and reacting in the presence of a first polymerization inhibitor and a first catalyst, alkylphenol polyoxyethylene ether in the alkylphenol polyoxyethylene ether (methyl) acrylate raw material and monoisocyanate with double bonds are subjected to an addition reaction to obtain an oligomer, and the treatment of the alkylphenol polyoxyethylene ether (methyl) acrylate raw material is completed. The method effectively solves the environmental safety problem caused by residual alkylphenol polyoxyethylene ether in alkylphenol polyoxyethylene ether (methyl) acrylate, the generated oligomer can participate in curing reaction, the generated coating can obtain better comprehensive performance, and a post-treatment process is not needed.

Description

technical field [0001] The invention relates to the field of polymers, in particular to a treatment method of alkylphenol polyoxyethylene ether (meth)acrylate, an oligomer, a coating raw material, a coating and a preparation method. Background technique [0002] Alkylphenol polyoxyethylene ether (meth)acrylate has the advantages of low viscosity, low glass transition temperature and good adhesion, and is usually used as a reactive monomer in coatings. Alkylphenol polyoxyethylene ether (meth)acrylate is prepared from alkylphenol polyoxyethylene ether and (meth)acrylic acid as reaction raw materials, so that the alkylphenol polyoxyethylene ether (meth)acrylate remains Alkylphenol polyoxyethylene ether. Alkylphenol ethoxylates will migrate to the surface of the cured coating, and then be released into the environment and quickly decompose into undesired environmental hormones alkylphenols. In recent years, alkylphenol ethoxylates have been listed as European regulations restr...
