Abstract

The invention provides an ultraviolet light curing monomer, which comprises the following raw materials: polyol, acrylic acid, a composite auxiliary agent, hypophosphorous acid, p-hydroxyanisole and asolvent; wherein the composite auxiliary agent is formed by compounding copper methanesulfonate and methanesulfonic acid, the copper methanesulfonate and methanesulfonic acid are compounded as the composite auxiliary agent, and the solvent is an organic solvent. Copper methanesulfonate of a composite auxiliary agent is used as a polymerization inhibitor, and methanesulfonic acid is used as a catalyst, wherein a catalytic esterification reaction is carried out under an acidic condition, so that the reaction efficiency is improved, and a compound of copper methanesulfonate and methanesulfonic acid is used as the composite auxiliary agent, so that the reaction efficiency is improved, and the product purity is also improved; furthermore, chlorine-containing compounds are completely preventedfrom being used as auxiliaries in the reaction process, stress corrosion of chloride ions to stainless steel equipment is avoided; therefore, the service life of the equipment is prolonged, the use amount of detergent can be greatly reduced, and the environmental goal of clean production is achieved.

Description

technical field [0001] The application belongs to the technical field of coatings, and in particular relates to a UV curing monomer, a preparation method of the UV curing monomer, and an application of the UV curing monomer. Background technique [0002] As people continue to pay attention to environmental protection and energy utilization, our country has increasingly restricted the emission of volatile organic compounds (VOC) in traditional solvent-based coatings. Environmentally friendly coatings have become one of the main directions for the development of the coatings industry. [0003] Ultraviolet curing technology (UV technology) refers to adding a photoinitiator (or photosensitizer) to a specially formulated system (called a photocuring system), after absorbing high-intensity ultraviolet light generated in ultraviolet (UV) photocuring equipment , to generate active free radicals or cations, thereby initiating polymerization, crosslinking and grafting reactions, makin...
