Embodiment 1

[0049] The preparation method of the environmental protection ecological board with high color fastness comprises the following steps:

[0050] (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;

[0051] 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;

[0052] The preparation of melamine-modified resin includes first two additi...

Embodiment 2

[0060] The preparation method of the environmental protection ecological board with high color fastness comprises the following steps:

[0061] (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;

[0062] 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;

[0063] The preparation of melamine-modified resin includes firs...

Embodiment 3

[0071] 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.

[0072] 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 It 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.

Abstract

The invention relates to a high-color-fastness environment-friendly ecological board and a preparation method, and belongs to the technical field of decorative materials. The high-color-fastness environment-friendly ecological board comprises a base board layer, buffer and balance layers and high-color-fastness facing layers. The level of the color fastness of the high-color-fastness facing layers reaches the fifth level or above. The upper surface and the lower surface of the base board layer are bonded to the buffer and balance layers through environment-friendly glue. The high-color-fastness facing layers are made of wood-grained paper soaked in melamine modified resin containing a light stabilizer. The high-color-fastness facing layers are bonded to the upper surfaces of the buffer and balance layers. The buffer and balance layers are made of poplar veneers or Eucalyptus veneers or technical wood veneers. The base board layer is made of multiply plywood or a core-board. A modified bio-based adhesive or a modified starch adhesive is used as the environment-friendly glue. A hindered amine compound is used as the light stabilizer. The high-color-fastness environment-friendly ecological board has the paint-free function and also has the performance of low formaldehyde emission and the high level of color fastness to light.

Description

technical field [0001] The invention relates to an environment-friendly ecological board with high color fastness and a preparation method thereof, belonging to the technical field of decorative materials. Background technique [0002] In the field of decorative materials technology, paint-free ecological boards are being widely used in the manufacture of household items due to their advantages of being paint-free, having various patterns and a rich product series. Paint-free ecological boards can be divided into plywood paint-free ecological boards, blockboard paint-free ecological boards, particleboard paint-free ecological boards and medium density fiberboard paint-free ecological boards according to their substrates. Currently on the market, these four common ecological paint-free decorative panels generally use urea-formaldehyde adhesives, and their environmental protection grades are generally low, generally E1 grades, and rarely reach E0 grades, and their poor color f...
