Technical Field

The invention relates to the technical field of papermaking, in particular to colored decorative paper and a preparation method thereof.

Background

Because the decorative paper is frequently scrubbed in order to prevent dust accumulation during use, and is easily abraded in the scrubbing process, the wear resistance is insufficient; the formaldehyde emission of some decorative papers is large and is not environment-friendly; the problems that the surface of the decorative paper is not bright enough, the definition is not high enough and the production process is relatively complex are the existing problems, and the decorative paper is difficult to meet the requirements of customers.

Disclosure of Invention

In order to solve the technical problems, the invention provides the colored decorative paper which has the advantages of reasonable formula, good wear resistance, long service life and small formaldehyde emission; the method has simple process and low production cost.

In order to achieve the object of the present invention, the present invention is implemented by the following embodiments:

a colored decorative paper comprises mixed impregnating compound and colored wear-resistant reinforcing phase; wherein the mixed impregnated glue is urea-formaldehyde glue and soybean glue; the color wear-resistant reinforced phase is made of superfine Al₂O₃Powder, superfine quartz stone powder and pigment powder.

Preferably, the ratio of urea-formaldehyde glue to soybean glue in the composite impregnating glue is 1: 2-5.

Preferably, the fineness of the superfine quartz powder is 4000-10000 meshes.

Preferably, the Al is₂O₃The fineness is 2000-5000 meshes.

Preferably, the fineness of the pigment powder is 2000-5000 meshes.

A method for preparing a colored decorative paper, characterized in that the method comprises:

1) compounding color enhancement phases: ultra-fine Al₂O₃The powder, the superfine quartz stone powder and the pigment powder are mixed according to the weight ratio of 5: 2: 0.1, fully and uniformly mixing to obtain mixed powder;

2) dipping and gluing the base paper in the mixed dipping glue solution;

3) uniformly spraying the colored composite reinforced powder on the wear-resistant surface of the impregnated paper;

4) drying to obtain the colored decorative paper.

Preferably, the total amount of the dipping and gluing is 120-400%.

Preferably, the addition amount of the composite reinforced powder is 20-30 g/m²。

Preferably, the drying temperature is 105-120 ℃, and the drying time is 2-5 h.

Compared with the prior art, the decorative paper prepared by the invention can obviously improve the performances such as wear resistance, strength and the like on the basis of increasing the color decoration, and simultaneously obviously reduces the process cost and the release amount of formaldehyde.
