A kind of self-wearing wood decoration material and its manufacturing method

Abstract

The invention provides a manufacturing method of self-wear-resisting wooden decorative material with simple process and equipment. Pressing will not wear out the polishing pad of the heat press. It includes the following steps: immersing the substrate suitable for impregnation into the impregnating resin and then taking it out; drying the impregnated substrate to make the surface of the substrate slightly sticky to the touch; putting the wear-resistant material of more than 100 meshes through the air-laid The loading machine is paved on the upper surface of the pre-dried substrate, and the paving amount of the wear-resistant material is 5-25g / m2; the substrate on which the wear-resistant material is paved is passed through a pair of round rollers to press the wear-resistant material. Firmly and firmly adheres to the surface of the substrate; the substrate is re-dipped in the impregnating resin and then placed in a dryer to dry again.

Description

technical field [0001] The invention relates to a novel wooden decorative material with self-wearing function and a manufacturing method thereof, belonging to the field of wood composite material manufacturing. Background technique [0002] Decorative materials in the general sense have been widely accepted as decorative materials because of their traditional characteristics of wood materials, high strength-to-weight ratio, and easy processing. [0003] The wear-resistant wooden decorative materials provided in the prior art generally have the following manufacturing processes: [0004] The first production process is to apply a primer on the surface of the substrate, then print the pattern, and then spray the wear-resistant layer to obtain a wooden wear-resistant decorative material. The wear-resistant layer is generally composed of aluminum oxide, etc., mixed with polyurethane resin (or amino acid resin, polyester resin, acrylic resin, vinyl resin, etc.) and corresponding...

Problems solved by technology

Its disadvantages: the surface paper with wear-resistant materials added to the center layer of the paper is expensive, and 80% depends on imports. The price of the surface paper with wear-resistant materials adhered to the surface of the paper is slightly lower, but it will fall off due to the wear of wear-resistant materials during use gradual loss of wear resistance

The disadvantages of liquid wear-resistant impregnated paper technology are: the formulation of melamine formaldehyde impregnated resin and the type and amount of additives must be specially designed to obtain the appropriate viscosity required to prevent the wear-resistant material from settling, and most factories do not have this ability ; And, in order to prevent the settlement of wear-resistant materials, the quality and particle size of wear-resistant materials must be screened, and the utilization rate of wear-resistant materials is low; due to the high viscosity of the mixture of melamine-formaldehyde resin used for spraying or showering, often If the nozzle is blocked, when the resin is sprayed on the surface of the impregnated decorative paper, the permeability of the resin is poor, and it will cause sagging, which will cause mountain-shaped stripes and uneven distribution of the wear-resistant material on the surface of the decorative paper; it is difficult to control the impregnated paper when spraying. Resin content, and the cost of wear-resistant materials with a certain sieve value is high, and damage to the polishing pad is still unavoidable
