Anion-impregnated integrated paper for ecological board veneer

Abstract

The invention discloses anion-impregnated integrated paper for an ecological board veneer. The anion-impregnated integrated paper is formed by a fiber layer and decoration paper in adhesive containing an anion material through simultaneous adhesive impregnation, rolling compositing and pre-curing. A production method of the anion-impregnated integrated paper includes: subjecting the fiber layer and the decoration paper to primary adhesive impregnation, rolling compositing, primary drying, secondary adhesive impregnation and secondary drying, cooling to room temperature, cutting edges, inspecting and packaging, wherein the fiber layer is geotechnical cloth, glass fabric, a polyamide fiber layer, a polyacrylonitrile fiber layer, a polyester fiber layer, a polypropylene fiber layer or ceramic fiber layer. The anion material is anion powder. The anion-impregnated integrated paper has advantages that the paper has buffer covering performance, is capable of saving resources, and the like. When the anion-impregnated integrated paper is used to produce an ecological board, the production procedure is simple and low in energy consumption, formaldehyde in the ecological board can be lowered effectively by continuously releasing anions, and human health is benefited.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to an anion-impregnated integrated paper for ecological board decoration. Background technique [0002] Ecological boards are also called melamine boards, melamine boards, and paint-free boards in the industry. At present, its main production process is generally as follows: use wood veneer as a buffer balance layer, and add a whole piece of wood veneer (usually poplar veneer) to the upper and lower surfaces of core boards such as blockboard blanks or plywood blanks. Board, known as poplar bark in the industry) group embryo, sent to the hot press for the first hot pressing, then removed from the hot press, covered with melamine-impregnated film paper on the outer surface of the wood veneer, and then sent to the hot press machine for the second hot press forming. [0003] There are three disadvantages of the above method: [0004] 1. It is generally necessary to cut down large-...

AI Technical Summary

Problems solved by technology

[0004] 1. It is generally necessary to cut down large-diameter wood to make the whole wood veneer, which is not conducive to ecological protection;

[0005] 2. The amount of adhesive used to make the core board is large and generally contains formaldehyde, resulting in a high amount of formaldehyde released from the finished board, which makes it difficult to meet the increasing consumer demand for high-quality environmentally friendly products;

[0006] 3. Two hot pressing processes are required, with more processes and higher energy consumption
