A kind of plate timber UV coating construction process
Technical field
The present invention relates to the technical field of chemistry painting industry construction method more particularly to a kind of plate timber UV coating decoration works
Skill.
Background technique
UV paint is photocureable coating, it is current using more extensive furniture lacquer, and main feature has: by intensive ultraviolet
Photocuring is handled, color stability, for a long time Chang Xin.UV paint film spatially shape structure, hardness is big, wearability is good, transparency is good, produces
The resistance to scraping collision of product, rub resistance, stand the test of time.UV paint in terms of be widely used.
The main technique of coating plate timber is that the first artificial big groove PE that carries out mends soil currently on the market, then polished,
Spraying twice or multiple PE/PU transparent priming carry out priming paint polishing again, finally carry out PU and repair color and finishing coat coating.It is such to apply
The problem of work technique will appear harmful substance volatilization in production process, influence health, and the production cycle is long, occupied ground
Greatly, coating product easily occurs to split cruelly, plays the problems such as pinprick tangerine peel, and polishing difficulty is very big.
Therefore, it is necessary to a kind of easy plate timber UV coating decoration method polished and paint film is smooth be developed, with solution
The certainly demand in market.
Summary of the invention
The present invention provides a kind of plate timber UV coating construction process for the deficiency of product on the market at present, successively into
Row three times roller coating UV compound type transparent putties, double roller painting UV transparent priming and sand millings, carry out roller coating UV later and repair color finishing coat and radium-shine roller
UV dull finishing coat is applied, can effectively solve that plate timber UV priming paint generates in coating process in this way is not easy sanding, not environmentally
Problem, the film thickness and paint film planarization which forms all are very significantly improved.
In order to solve the above-mentioned technical problem, the present invention realizes by the following technical programs:
A kind of plate timber UV coating construction process, comprising the following steps:
