Dry spraying decorative paper and manufacturing technology thereof

Abstract

The invention provides dry spraying decorative paper for manufacturing a wood floor and a manufacturing technology thereof. The dry spraying decorative paper comprises printing base paper, wherein the upper surface of the printing base paper is printed with decorative patterns, the upper surface of the printing base paper is coated with an attachment glue layer, the lower surface of the printing base paper is coated with a binding glue layer which is used for binding a floor substrate layer, a wear-proof material layer is formed on the upper surface of the attachment glue layer by a dry powder spraying mode, and a cover glue layer is repeatedly coated on the upper surface of the wear-proof material layer. The dry spraying decorative paper radically solves the problems of distribution uniformity of powder particles, attachment ability, resin coating and melting effect, flocculation and deposition in a use process, not only ensures the wear-proof revolution stability, but also ensures the definition of a woody panel simultaneously. In addition, the scattered wear-proof powder particles also can be recovered and recycled so as to reduce the waste and save the cost.

Description

technical field [0001] The present invention relates to a kind of spraying decorative paper used for making wooden floor, and also relates to the manufacturing process of the spraying decorative paper. Background technique [0002] At present, the structure of some wooden floors on the market is as follows: figure 1 As shown, this type of wooden floor is formed by laminating the sprayed decorative paper 1', the base layer 2' and the balance layer 3', wherein the sprayed decorative paper 1' covers the upper surface of the base layer 2', and the balance layer 3' Covering the lower surface of the substrate layer 2'. Generally, the spraying decorative paper used in the manufacture of such wood floors refers to liquid spraying paper (also known as wet spraying paper). The resin is used as the carrier, and the wear-resistant powder particles (such as Al 2 o 3 Powder particles) and cellulose are mixed and stirred evenly, and then the mixed liquid is evenly sprayed on the surfac...

AI Technical Summary

Problems solved by technology

Thanks Al 2 o 3 Granules are hard, which will cause serious wear and tear on thick slurry pumps, metering rollers and other devices, and the maintenance costs will be high

At the same time, cellulose can also make the clarity difficult to control

The disadvantage of this traditional wet spraying process is that it cannot intuitively grasp Al 2 o 3 Distribution of powder particles, Al 2 o 3 The powder particle distribution is affected by the fluidity of the resin, Al 2 o 3 Al 2 o 3 The distribution of powder particles is uneven, so that the wear resistance of the product (the expression of wear resistance, the higher the wear resistance, the better the wear resistance of the product) is not stable enough
