Problems solved by technology

The above-mentioned patented technologies all use woodworking boards and plywood instead of traditional density boards and particle boards and other substrates, and are produced by low temperature, small pressure, long-term pressure holding, and multiple pressing process production methods, which cannot achieve mass production. Production The resulting products have a lot of fatal defects such as delamination, degumming, deformation, surface hardness, scratch resistance and poor wear resistance during later use.

Embodiment 1

[0025] figure 1 It is a schematic structural diagram of an ecological board, which includes a melamine-impregnated film paper 1 , a special-shaped veneer 2 and an intermediate substrate 3 . The method for preparing an ecological board comprises the following steps:

[0026] Step 1: Prepare melamine-impregnated film paper. During the preparation process, the amount of gluing is increased by 15-20% compared with the traditional formula, that is: the content of melamine is adjusted to 70%, the proportion of gluing amount of triammonium reaches 145%, and the volatile matter content Tune to: 5.0.

[0027] Step 2, press and paste the melamine-impregnated film paper on the special-shaped veneer;

[0028] The thickness of the special-shaped veneer is required to be about 60S, and the size is four to eight feet. It is required that the entire veneer has no dead knots, no insect holes, no yin and yang sides, no color difference, no jamming, and no horizontal knife marks during rotary ...

Embodiment 2

[0035] Step 1: Prepare melamine-impregnated adhesive film paper. During the preparation process, the amount of gluing is increased by 15-20% compared with the traditional formula, that is, the content of melamine is adjusted to 100%, the ratio of gluing amount of triammonium reaches 160%, and the volatile matter content Adjust to 6.0.

[0036] Step 2, press and paste the melamine-impregnated film paper on the special-shaped veneer;

[0037] The thickness of the special-shaped veneer is required to be around 80S, and the size is four to eight feet. It is required that the entire veneer has no dead knots, no insect holes, no yin and yang sides, no color difference, no jamming, and no horizontal knife marks during rotary cutting. The type of veneer is Kauri.

[0038] Said pressing refers to placing the melamine-impregnated film paper horizontally on the special-shaped veneer, and then putting it into a press for pressing.

[0039] The pressing is specifically as follows: the te...

Embodiment 3

[0044] Step 1: Prepare melamine-impregnated adhesive film paper. During the preparation process, the amount of glue added is increased by 15-20% compared with the traditional formula; Content adjusted to: 6.5.

[0045] Step 2, press and paste the melamine-impregnated film paper on the special-shaped veneer;

[0046] The thickness of the special-shaped veneer is required to be about 70S, and the size is four to eight feet. It is required that the entire veneer has no dead knots, no insect holes, no yin and yang sides, no color difference, no jamming, and no horizontal knife marks during rotary cutting. The type of veneer is poplar.

[0047] Said pressing refers to placing the melamine-impregnated film paper horizontally on the special-shaped veneer, and then putting it into a press for pressing.

[0048] The pressing is specifically as follows: the temperature of the upper and lower templates of the press is 170° C., the pressure is 25 Pa, and the holding time is 2 minutes.

Abstract

The invention discloses a preparation method of an ecological plate, which comprises the following steps of: step 1, preparing melamine impregnated cellophane paper, wherein glue content is increased by 15-20% in the preparation process in comparison with a traditional formula; step 2, attaching the melamine impregnated cellophane paper on special-shaped veneers; step 3, preparing an intermediate substrate; step 4, respectively adhering the veneers attached with the melamine impregnated cellophane paper to two surfaces of the intermediate substrates, and pressing and heating the two surfaces of the intermediate substrate to get the ecological plate. In the preparation method provided by the invention, a grainy paper for printing substitutes a natural wood material to serve as a decorative finish of the plate, so that usage amount of wood is greatly reduced, and non-renewable resource is saved; oil paint is substituted after the surface of the plate is impregnated by melamine, so that cost on processing is greatly saved, processing time is greatly shortened, and environmental performance of the preparation method is far better than that of the conventional production method; and the prepared ecological plate is excellent in surface abrasive resistance, scratch resistance, stain resistance and fire resistance, and is fashionable in design and color expression, so that the prepared ecological plate can meet the requirements of different consumers.

Description

technical field [0001] The invention relates to an ecological board in the technical field of household raw materials and boards, in particular to a preparation method of the ecological board. Background technique [0002] At present, the boards used in furniture and home decoration in the domestic market can be roughly divided into: rough boards, woodworking boards, plywood, veneer boards, density boards, particle boards, etc. The usual board applications in the industry are generally divided into: painting, stickers, and three-ammonia adhesive paper, etc., all of which have disadvantages and defects. Common civil processing methods have long processing periods, are not environmentally friendly, have long-term odors, and poor manual craftsmanship on the surface, etc. The problem is that there are basically problems such as large amount of formaldehyde released by manufacturers, easy to be affected by moisture, large amount of glue used, high water expansion rate, and seriou...
