Problems solved by technology

[0005] Since the development of WPC radiation curing, there have been relatively mature formulas and processes, but there are also some problems, mainly the problem of anti-oxygen polymerization inhibition, the performance of low-dose cross-linking curing; and other problems such as reducing the volatilization of organic monomers to reduce The cost of organic monomers, etc.; these are issues that affect the real practicality of radiation-cured WPC technology
[0006] Chinese patent CN 104441136B discloses a process of urea-formaldehyde resin impregnation and electron beam radiation curing to make wood-plastic composite materials, which solves the above technical problems, but this process is prepolymerized in formaldehyde and urea, and then mixed with carbon tetrachloride to form Impregnation solution, all performances are good, but it is slightly lacking in environmental protection issues. At present, with the improvement of people's living standards, floor decoration and maintenance occupy a very important position in home decoration. People's attention is often focused on the floor coating. Environmental aspect

The invention provides a novel formula of the electron beam radiation curing coating for wooden floor and a preparation methodthereof. by using 1,4-butanediol divinyl ether as a reactive diluent, high curing speed, low processing temperature, fast drying and low curing radiation dose are guaranteed for the electron beam radiation curing coating for wooden floor, and the environmental protection requirement is met.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic composite materials, in particular to an electron beam radiation-cured wood floor paint. Background technique [0002] The method of rapidly converting liquid organic monomers into solids by radiation is called "radiation curing". Common radiation sources include lasers, ultraviolet light, gamma radiation sources and EB radiation sources. Compared with traditional thermal curing methods, radiation curing usually has the advantages of low energy consumption, less pollution, high quality, and fast processing speed, and can be applied in the field of curing polymer materials such as coatings, inks, and adhesives. And wood-plastic composites (Wood Plastic Composites, WPC) also belong to an important branch of radiation curing. The so-called WPC refers to the impregnation of active organic monomers or prepolymers into the pores of wood, and then triggers the polymerization, crosslinking or grafti...
