Problems solved by technology

[0002] Because the decorative paper is often scrubbed to prevent the accumulation of dust during use, and it is easy to wear during the wiping process, which shows that the wear resistance is not enough; some decorative paper releases a large amount of formaldehyde, which is not environmentally friendly; the surface of the decorative paper is not bright enough , the definition is not high enough, and the production process is relatively complicated. These problems make it difficult for decorative paper to meet customer requirements.

Abstract

The invention discloses a composite decoration paper preparation method, which comprises: preparing a modified impregnation liquid: weighting 20-30 parts by mass of formaldehyde, 18-25 parts by mass of melamine, 3-5 parts by mass of diethylene glycol, 1-2 parts by mass of sodium hydroxide and 4-7 parts by mass of water, adding into a reaction kettle, continuous stirring, slowly heating to 60-80 DEG C, stopping the heating, carrying out thermal insulation for 30 min, adding 20-40 parts of soybean glue, cooling to 40-45 DEG C, adding 2-5 parts of an aldehyde removing agent into the reaction kettle, and cooling to a room temperature so as to spare; completely and uniformly mixing 5-8 parts by mass of ultrafine Al2O3 powder, 1-3 parts by mass of ultrafine quartzite powder and 0.1-0.3 part by mass of pigment powder in a ball mill to obtain composite reinforced powder; dipping; carrying out spray coating; and drying. According to the preparation method of the invention, the raw material formula is reasonable, the prepared decoration paper is good in wear resistance, the service life of the decoration paper is prolonged, the formaldehyde emission is reduced, and the method is simple in process and reduces the production cost.

Description
