Composite floor surface layer, composite floor and manufacturing method thereof

Abstract

The invention discloses a manufacturing method for the surface layer of a composite floor, which solves the problems of the wear-resistant layer of the surface layer of the composite floor, such as a fragile press, low anti-pollution ability, poor simulation degree, and the like. The steps of the method of the present invention are as follows: the decorative paper roll enters the dipping tank, and then sprinkles aluminum oxide particles to obtain the decorative wear-resistant paper; the wood pulp fiber paper roll enters the dipping tank for dipping to obtain the surface anti-fouling paper; the decorative anti-fouling paper The abrasive paper and the surface anti-fouling paper are laminated together and enter the first heat-seal drying oven for drying; the laminated decorative wear-resistant paper and surface anti-fouling paper are sized by the secondary surface sizing coater and then enter the second heat-sealing drying oven. Seal the drying box to make it fit, and finally cut to obtain the composite floor surface. Adopting the invention has the advantages of high wear resistance, high pollution resistance and high simulation, and does not damage the press.

Description

technical field [0001] The present invention relates to a laminate flooring surface for use in the manufacture of laminate flooring and to a method for the manufacture of the surface. Background technique [0002] The wear-resistant layer of the surface layer of the composite floor is generally obtained by adding aluminum oxide particles to the pulp to make wear-resistant paper, then impregnated with resin and placed on the decorative wood grain paper impregnated with resin to form the surface layer of composite floor, and finally pressed under high temperature and high pressure Paste on the substrate to make a composite floor. The problem with this method is that the paper in the wear-resistant paper is completely the carrier of Al2O3 particles, and the higher the number of wear-resistant revolutions, the higher the content of Al2O3 is required, and at the same time, the corresponding increase in pulp is required. When the pulp is correspondingly increased, the clarity of ...

AI Technical Summary

Problems solved by technology

The problem with this method is that the paper in the wear-resistant paper is completely the carrier of aluminum oxide particles. The higher the number of wear-resistant rotations, the higher the content of aluminum oxide is required, and the corresponding increase in pulp is required.

Due to the high specificity of Al2O3, the coating liquid moves slowly, and it is easy to form a dead zone, causing the Al2O3 particles to sink, resulting in uneven roll coating or spraying of Al2O3 on the decorative paper, which leads to the adoption of this method The wear-resistant speed strength of the surface layer of the manufactured composite floor is not up to the standard or changes greatly

In order to slow down the sinking rate of aluminum oxide, several known methods use finer particles and cellulose derivatives that can increase the viscosity of the paint, but this will affect the gloss and simulation of the laminate floor surface, and this Produces laminate floors that are less resistant to stains

And because the aluminum oxide particles are very hard, when the press fits them on the floor, the aluminum oxide particles will damage the steel plate of the press machine, and after the aluminum oxide particles are pressed, the surface of the aluminum oxide particles is cracked and easy to accumulate dirt. Produced floors have poor stain resistance and look old after a short period of use
