Embodiment 1

[0015] Example 1, the manufacturing method of E0 grade flame-retardant, wear-resistant, mildew-proof and moisture-proof veneer veneer plywood, the process steps are as follows:

[0016] 1. Select the dried veneer (moisture content 8%);

[0017] 2. Apply glue on both sides of the veneer, the amount of glue applied is 280 grams per square meter; the adhesive is modified urea-formaldehyde resin, adding 5% of the weight of the adhesive and 5% of the flame retardant; the said Flame retardants such as boron flame retardants, etc., said antifungal agents such as copper and alkylammonium compound antifungal agents

[0018] 3. After gluing, the blanks are assembled. The veneer structure layer of the blank assembly is three layers, and the wood grain directions of adjacent veneers are perpendicular to each other;

[0019] 4. Pre-pressing treatment after billet assembly, the pre-pressing pressure is 0.2MPa, the temperature is room temperature, and the time is 0.5 hours;

[0020] 5. Aft...

Embodiment 2

[0026] The manufacturing method of E0 flame-retardant, wear-resistant, mildew-proof and moisture-proof type veneer veneer plywood, the process steps are as follows:

[0027] 1. Select the dried veneer (moisture content 9%);

[0028] 2. Carry out double-sided gluing of the veneer, the amount of gluing is 300 grams per square meter; the adhesive is modified urea-formaldehyde resin, adding 7% of the weight of the adhesive and 8% of the flame retardant; the said Flame retardants such as boron flame retardants, etc., said antifungal agents such as copper and alkylammonium compound antifungal agents

[0029] 3. After gluing, the blanks are assembled. The veneer structure layer of the blank assembly is five layers, and the wood grain directions of adjacent veneers are perpendicular to each other;

[0030] 4. Pre-pressing treatment after billet assembly, the pre-pressing pressure is 0.4MPa, the temperature is room temperature, and the time is 1.5 hours;

[0031] 5. After the pre-pre...

Embodiment 3

[0037] The manufacturing method of E0 flame-retardant, wear-resistant, mildew-proof and moisture-proof type veneer veneer plywood, the process steps are as follows:

[0038] 1. Select the dried veneer (moisture content 10%);

[0039] 2. Apply glue on both sides of the veneer, the amount of glue applied is 320 grams per square meter; the adhesive is a modified urea-formaldehyde resin, and 10% of the weight of the adhesive is added with a flame retardant and 10% of an antifungal agent; Flame retardants such as boron flame retardants, etc., said antifungal agents such as copper and alkylammonium compound antifungal agents

[0040] 3. After gluing, the blanks are assembled. The veneer structure layer of the blank assembly is seven layers, and the wood grain directions of adjacent veneers are perpendicular to each other;

[0041] 4. Pre-pressing treatment after billet assembly, the pre-pressing pressure is 0.5MPa, the temperature is room temperature, and the time is 2.0 hours;

Abstract

The invention relates to a method for manufacturing E0 grade veneer overlaid plywood with inflaming retardance, abrasion resistance, rot resistance and moisture protection. The method comprises the following steps: selecting a dried veneer; rubberizing the veneer in two sides; assembling after rubberizing, with veneer structure layers being odd number; carrying out prepressing treatment after assembly; carrying out hot pressing treatment after the prepressing treatment; entering naturally cooling, depositing and sanding after the hot pressing treatment; coating masking agent, which is to apply aldehydeless gummy masking agent on a baseplate of the plywood to cover color difference of the baseplate surface to lead the baseplate surface to be in light yellow; applying E0 grade urea-formaldehyde resin adhesive on the baseplate by a pasting machine after the masking agent is dried; and pasting veneer on the baseplate, and carrying out abrasion-resistant treatment to the surface after hot pressing. The method has the advantages that the veneer overlaid plywood is an environment-friendly decoration material reaching E0 grade, has the functions of inflaming retardance, rot resistance, moisture protection and abrasion resistance, achieves the bonding strength of national standard, has mature manufacturing process, can implement industrial production so as to greatly improve the production efficiency and ensure product quality, and is convenient for popularization and application.

Description

technical field [0001] The invention relates to a method for manufacturing E0-grade flame-retardant, wear-resistant, mildew-proof and moisture-proof veneer veneer plywood, which belongs to the technical field of wood-based panel manufacturing. Background technique [0002] In view of the serious impact of formaldehyde on human health, the country has made strict regulations on the amount of formaldehyde released in wood-based panel products. "GB18580-2001 mandatory standard, since July 1, 2002, the market will stop selling products that do not meet the national standard. Developed countries such as Japan and Europe have proposed and implemented higher standards E 0 Level (ie ≤0.5mg / L). This level of wood-based panels is difficult to manufacture due to their high technical content. Contents of the invention [0003] The invention proposes a method for manufacturing E0-grade flame-retardant, wear-resistant, mildew-proof and moisture-proof veneer veneer plywood, aiming at ...
