Embodiment 1

[0046] The preparation method of the environmental protection ecological board comprises the following steps:

[0047] (1) Disperse the hindered amine light stabilizer in the melamine modified resin, and then carry out the first impregnation treatment, the first drying, the second impregnation treatment, and the second drying of the wood grain paper in it. High color fastness finish layer; hindered amine light stabilizer is a liquid hindered piperidinyl compound, the dosage is 5% of the mass of melamine modified resin;

[0048] Wherein, the process of dispersing the light stabilizer in the melamine modified resin includes: 1. Weigh 100 parts of the melamine modified resin and 5 parts of the light stabilizer in parts by mass; 2. Add the light stabilizer while stirring in the melamine modified resin, Stirring speed ≥ 1000 rpm, evenly disperse the light stabilizer in the resin;

[0049] The preparation of melamine-modified resin includes first two addition polycondensation of me...

Embodiment 2

[0061] The preparation method of the environmental protection ecological board comprises the following steps:

[0062] (1) Disperse the hindered amine light stabilizer in the melamine modified resin, and then carry out the first impregnation treatment, the first drying, the second impregnation treatment, and the second drying of the wood grain paper in it. Obtain a high color fastness finish layer; hindered amine light stabilizer is a liquid hindered piperidinyl compound, the dosage is 20% of the mass of melamine modified resin;

[0063] Wherein, the process of dispersing the light stabilizer in the melamine modified resin comprises: 1. Weigh 100 parts of the melamine modified resin and 20 parts of the light stabilizer in parts by mass; 2. Add the light stabilizer while stirring in the melamine modified resin, Stirring speed ≥ 1000 rpm, evenly disperse the light stabilizer in the resin;

[0064] The preparation of melamine-modified resin includes first two addition polyconden...

Embodiment 3

[0076] Same as Example 1, except that the hindered amine light stabilizer in step (1) is UV-765, and the dosage is 8% of the mass of the melamine-modified resin.

[0077] Step (2) after hot pressing and step (3) between applying environmental protection glue also includes dyeing treatment, in which ternary compound dyes are used; ternary compound dyes are liquid hindered piperidinyl compounds, flame retardants and azo The dye is a ternary compound dye compounded according to the mass ratio of 1:25:300. Azo dyes have a molecular weight of 500-600 Daltons and a cubic crystal structure.

[0078] The final environmentally friendly ecological board includes a substrate layer, a buffer balance layer and a high color fastness finish layer; the color fastness level of the high color fastness finish layer reaches level 5 or above;

[0079] The upper and lower surfaces of the substrate layer are bonded to the buffer balance layer through environmental protection glue;

[0080] The fin...

Abstract

The present invention involves a preparation method of an environmentally friendly ecological board, which is a technical field of decorative materials.It includes the following steps: (1) Divide the blocked amine light stabilizer in the melamine modified resin, and then the first impregnation treatment, the first drying, the second impregnation treatment, the second immersion treatment, the second immersion treatment,The second drying system is high -colored, the fairy decoration layer; the scattered process of the light stabilizer includes: ① 100 parts of melamine modified resin according to the quality portion, 5 to 20 copies of the light stabilizer; ② in the melamine modified resinAdd an optical stabilizer while mixing; (2) compose the high -color target surface layer and the buffer balance layer of the single board for heat pressure;The formation of the plate is composed of the upper and lower surfaces of the substrate layer of the environmentally friendly plastic.The invention decorative board has the performance of low formaldehyde release and high level of light resistance.

Description

technical field [0001] The invention relates to an environment-friendly ecological board and a preparation method thereof, belonging to the technical field of decorative materials. Background technique [0002] In the technical field of decorative materials, after the decoration of plywood, blockboard and veneered panels, indoor toluene, xylene and other odors can not dissipate for a long time, seriously affecting the indoor environment and restricting the use of this product; impregnated paper veneer wood-based panels (blockboard Board core, plywood core, also known as "environmental protection ecological board") construction speed is fast, indoor volatile organic matter is less, more and more favored by consumers, but the molar ratio of urea-formaldehyde resin and melamine-formaldehyde resin used for impregnating paper is too high High, the amount of formaldehyde emission is significantly higher than that of ordinary wood-based panels; and most of the brightly colored pigm...
