A wood grain paint layer is coated on the surface of a bamboo floor base material, and the preparation method specifically comprises the following steps: performing pretreatment on the surface of the bamboo floor base material, coating a primer coat through a roller, curing the primer coat, coating a top coat through the roller and curing the top coat. According to the preparation method of the wood grain bamboo floor, the problems of low utilization rate of bamboo materials due to non-consistent colors of the existing bamboo floor, poor practicality of the bamboo floor after the existing surface treatment and the like can be solved, and the preparation method has the advantages of simple process steps, convenience in operation, strong practicality and the like.

Description

A kind of preparation method of Wood grain bamboo floor

Technical field

The present invention relates to a kind of bamboo floor preparation method, be specifically related to a kind of preparation method of Wood grain bamboo floor.

Background technology

Bamboo floor and solid wooden floor board, laminated flooring, solid wooden compound floor belong to the four big series products that timber floor comprises together, and wherein the bamboo floor is mainly to be the floor that main production raw material processes through special process with the mao bamboon.The bamboo floor is a kind of new decorative material for building, and it is a raw material with natural high-quality bamboo, through twenties procedures, sloughs the former juice of bamboo, pieces together through HTHP and presses, and again through 3 layers of paint, last infrared baking forms.The bamboo floor is brought one green pure and fresh wind with the many premium properties after its natural advantage of giving and the moulding to the building materials market.There is the native texture of bamboo on the bamboo floor, and is pure and fresh elegant, gives a kind of back to nature of people, elegance sensation free from vulgarity.At present the bamboo floor has become a kind of floor decorative material of top grade, is popular in America and Europe, Southeast Asia and Middle East.

The bamboo floor solely with fine and smooth, smooth smooth, the clean mark of its quality, color and luster is elegant, delicate fragrance is pleasant and physical and mechanical properties such as MOR, elastic modelling quantity are higher than characteristics such as timber floor; Just progressively by consumers in general accept, like, developed into indispensable a kind of new terrestrial ornament materials.

Yet also there are many deficiencies in the bamboo floor, mainly is Natural color like the color on most of bamboo floor on the market, and the floor tone is more single, has had a strong impact on its sale and use.Therefore; Must carry out decorative Treatment to the bamboo chip that constitutes the floor or the blank surface on molded floor if obtain high-grade bamboo floor, so that bamboo floor surface bamboo chip color and luster is pure and fresh, fiber alignment does not neatly have small holes caused by worms, mildew, stain, black line flawless, lack limit noresidue surf green, tabasheer.The existing bamboo floor surface is handled is employed in stickup wood grain ply of paper on the bamboo matter body more, and the permanent back of using is prone to come off poor practicability.A kind of processing method of bamboo floor surface detail is disclosed like Chinese patent CN101357562B; This method is with heat-transferring printing paper decorative pattern to be transferred on the surface on bamboo floor, is specially first image with decorative pattern and passes through printer prints to heat-transferring printing paper, again heat-transferring printing paper is placed on the bamboo floor surface; And be transferred to the surface on bamboo floor with transfer interpreter; Though this invention has changed the single deficiency of bamboo floor designs and varieties, has improved the market competitiveness on bamboo floor, decorative pattern is insecure; Tack is poor, very easily comes off after having used of a specified duration.

Summary of the invention

The problems such as bamboo floor poor practicability that the object of the invention has been to solve after the inconsistent and existing surface treatment of existing bamboo floor color provide a kind of operation simple, and are easy to operate, the preparation method of practical Wood grain bamboo floor.

Above-mentioned technical purpose of the present invention is achieved through following technical scheme: a kind of preparation method of Wood grain bamboo floor is characterized in that: be covered with the graining liquid enamelled coating in bamboo floor base material surfaces coated, specifically may further comprise the steps:

(1) preliminary treatment is carried out on bamboo floor base material surface: after the base material sanding, apply the water-based adhesive agent, oven dry again, the transparent putty of roller coat is dried again then, and the transparent putty of roller coat is dried again again, and last sanding is smooth;

(2) priming paint roller coat and curing: will pass through pretreated bamboo floor roller coat priming paint, the sanding of oven dry back, roller coat photocuring printing-ink again, oven dry, roller coat priming paint again, baking roller coat priming paint again after half-dried, baking is to half-dried again, repeat three times after sanding;

(3) finish paint roller coat and curing: roller coat photocuring finish paint, oven dry repeats twice, gets product.

As of the present invention preferred, said priming paint viscosity is that 150 ~ 200s/ is coated with the 4-viscosimeter, and the priming paint roller coat of this viscosity is effective, strong adhesion.

In sum; The present invention compared with prior art has following outstanding advantage and beneficial effect: the bamboo floor through method preparation of the present invention presents the unique texture like solid wood, has enlarged the pattern on bamboo floor; The problems such as bamboo floor poor practicability after the low and existing surface treatment of the inconsistent utilization rate of bamboo that causes of existing bamboo floor color have been solved; Operation of the present invention is simple, and is easy to operate, practical.

The specific embodiment
