Description

A kind of construction method of wood product surface paint
Technical field
The present invention relates to painted surface treatment process fields, and in particular to a kind of construction method of wood product surface paint, It is mainly used for the construction processing of the surface paint of timber floor, can be also used for the construction of the wood product surfaces such as furniture, timber paint Processing.
Background technology
With national consumption level and to the raising of environmental requirement, people have when selecting woodwork it is more selection and Higher requirement, such as require woodwork closer to the essential color and texture texture of timber.
The weatherability of traditional wood products, solid wooden floor board or solid wooden compound floor is poor, humidity and temperature change compared with It is long-term in use, easy to produce deformation and cracking in big environment, poor dimensional stability.Especially timber floor, humidity compared with In use, easy ting produce discoloration, rotten, stability is poor in high environment.Thus, one layer can be covered in traditional timber floor enough The painting layer of thickness is also easy to produce discoloration, deformation, rotten when preventing timber floor from being used in the higher environment of humidity ratio to reach Generation, improve the dimensional stability of timber floor.
Although current treatment process ensure that the waterproof corrosion resisting property of timber floor, still, also covered in wood floor surface One layer of thicker protective film, is unable to the textural aesthetic and sense of touch of timber essence.And consumer is more desirable to when choosing timber floor Selection wood surface has compared with thin protective layer, can embody the texture and sense of touch of timber essence.For this problem, there is one on the market Product after a little improvement, such as protective layer is formed using wood wax oil dry vegetable oil, but since it is plant component, hard The performance requirement of traditional paint is not achieved on degree, wear-resisting and high temperature resistant, resistance to acid and alkali.
Therefore, more and more wooden product enterprises are highly desirable can have a kind of product that can solve the above problems.
Invention content
