Problems solved by technology

[0002] Plywood is one of the commonly used materials for furniture and one of the three major wood-based panels. It can also be used in airplanes, ships, trains, automobiles, buildings and packing boxes. No matter where it is used, it is closely related to people. The current market There are many brands of plywood on the market, the quality is uneven, and many of them are not flame-retardant. The main materials of plywood are wood and adhesives. Large loss; and the wood in the plywood has a strong water absorption capacity, and it is easy to absorb water and mold in a humid environment. Long-term mold will cause great damage to the plywood and shorten the service life of the plywood
[0003] The existing patent document CN 107520914 A discloses a flame-retardant plywood processing technology, specifically discloses a flame-retardant plywood, including a base layer, a reinforcement layer and a flame-retardant layer, which has flame-retardant and mildew-proof functions, but the reinforcement The steel plate with a thickness of 0.1~0.3mm is selected for the first layer. The steel plate itself has flame-retardant and mildew-proof properties, but it will increase the weight of the plywood, which is inconvenient for transportation. The direct joint with the board will obviously increase the difficulty of using the plywood

Embodiment 1

[0020] A preparation method for flame-retardant and mildew-proof plywood, comprising the following steps:

[0021] (1) Veneer preparation: Cut the wood into 2m-long wood sections, and perform rotary cutting on the wood so that the thickness of the veneer is 0.4~0.6mm to obtain the veneer;

[0022] (2) Soaking: Put the veneer in the flame-retardant and anti-mildew solution, and soak it at 2°C for 6 hours, so that the flame-retardant and anti-mold liquid can fully immerse the veneer to play a better role in flame retardant and anti-mold, take it out, drain, and get Soak the veneer; the flame retardant and antimold liquid in the step (2) is composed of the following raw materials in parts by weight: sodium silicate 22, antimony trioxide 16, tetrabromobisphenol A 11, neem extract 8, acetic acid 55. Water 1200, safe and healthy, avoid formaldehyde emitted by traditional plywood, and will not cause harm to the human body; for the extract of neem fruit, crush the neem fruit, add wate...

Embodiment 2

[0030] A preparation method for flame-retardant and mildew-proof plywood, comprising the following steps:

[0031] (1) Veneer preparation: Cut the wood into 2m-long wood sections, and perform rotary cutting on the wood so that the thickness of the veneer is 0.4~0.6mm to obtain the veneer;

[0032] (2) Soaking: Put the veneer in the flame-retardant and anti-mildew solution and soak it at 4°C for 7 hours, so that the flame-retardant and anti-mold liquid can fully immerse the veneer to play a better role in flame retardant and anti-mold. Take it out and drain to get Soak the veneer; the flame-retardant and anti-mold liquid in the step (2) is composed of the following raw materials in parts by weight: sodium silicate 23, antimony trioxide 17, tetrabromobisphenol A 12, neem extract 9, acetic acid 58. Water 1300, safe and healthy, avoid formaldehyde emitted by traditional plywood, and will not cause harm to the human body; for the extract of neem seeds, crush the neem seeds, add wat...

Embodiment 3

[0040] A preparation method for flame-retardant and mildew-proof plywood, comprising the following steps:

[0041] (1) Veneer preparation: Cut the wood into 2m-long wood sections, and perform rotary cutting on the wood so that the thickness of the veneer is 0.4~0.6mm to obtain the veneer;

[0042] (2) Soaking: Put the veneer in the flame-retardant and anti-mildew liquid, and soak it at 6°C for 8 hours, so that the flame-retardant and anti-mold liquid can fully immerse the veneer to play a better role in flame retardant and anti-mold, take it out, drain, and get Soak the veneer; the flame retardant and antimold liquid in the step (2) is composed of the following raw materials in parts by weight: sodium silicate 24, antimony trioxide 18, tetrabromobisphenol A 13, neem extract 10, acetic acid 60. Water 1400, safe and healthy, avoid formaldehyde emitted by traditional plywood, and will not cause harm to the human body; for the extract of neem seeds, crush the neem seeds, add water...

Abstract

The invention mainly relates to the technical field of artificial board processing, and discloses a preparation method for flame-retardant and moldproof plywood. The preparation method comprises veneer preparation, soaking, drying, freezing, gluing and hot pressing. According to the preparation method for flame-retardant and moldproof plywood, the obtained plywood has high flame-retardant and moldproof properties, the flame-retardant grade reaches V-1 level, the moldproof rate reaches 92.4%, and the practicability of the plywood can be obviously improved; the veneer obtained by rotary cuttingis immersed in flame-retardant and moldproof liquid at low temperature for a long time, the flame-retardant and moldproof liquid is fully immersed into the veneer, and a good flame resistance and moldprevention role is played; and the flame-retardant and moldproof liquid is safe and healthy, the situation that traditional plywood emits formaldehyde is avoided, and no harm is caused to human bodies.

Description

technical field [0001] The invention mainly relates to the technical field of wood-based panel processing, in particular to a method for preparing flame-retardant and mildew-proof plywood. Background technique [0002] Plywood is one of the commonly used materials for furniture and one of the three major wood-based panels. It can also be used in airplanes, ships, trains, automobiles, buildings and packing boxes. No matter where it is used, it is closely related to people. The current market There are many brands of plywood on the market, the quality is uneven, and many of them are not flame retardant. The main materials of plywood are wood and adhesives, which are easy to burn when exposed to open flames, producing a large amount of harmful gases, which will cause harm to the human body and the environment. Large loss; and the wood in the plywood has a strong water absorption capacity, which is very easy to absorb water and mold in a humid environment. Long-term mold will ca...
