Description

Technical Field

[0001] The invention relates to the technical field of particle board manufacturing, and in particular to a manufacturing process of an anticorrosive, anti-moth and flame-retardant particle board. Background Art

[0002] Particle board is a man-made board made of wood or wood poles, logs broken into pieces, and glued together under heat and pressure after applying adhesive. Its cross section presents a honeycomb-shaped board. As a new, high-end and environmentally friendly substrate, particle board is widely used by furniture manufacturers in Europe and the United States. The domestic high-end panel furniture market has also begun to adopt this type of board on a large scale. Since particle board uses wood scraps as raw materials, the wood fiber particles in the board are larger, and more of the essence of natural wood is retained. It is a new, environmentally friendly substrate with a smooth and delicate surface, no defects such as knots and worm eyes, good stability, and uniform material.

[0003] After the particle board is processed and formed, in order to avoid decay, insect damage and flame retardancy during use and to increase the service life of the particle board, the particle board needs to be treated with decay, insect damage and flame retardancy. At present, the most common method is to spray anti-corrosion, anti-moth and flame retardant agents on the surface of wood fragments. However, the spraying method cannot make the agents fully penetrate into the wood cells, and cannot achieve long-term anti-corrosion and anti-moth effects, resulting in poor quality of the particle board. Summary of the invention

[0004] In view of the defects of the prior art, the purpose of the present invention is to provide a process for manufacturing a corrosion-resistant, moth-proof and flame-retardant particle board to solve the problems raised in the above-mentioned background technology.

[0005] The present invention solves the technical problem by adopting the following technical solution:

[0006] The present invention provides a process for manufacturing an anticorrosive, anti-moth and flame-retardant particle board, comprising the following steps:

[0007] Step 1: remove the leaves and roots of the wood, then shave to obtain sawdust, and then sieve the sawdust to obtain sawdust for later use;

[0008] Step 2: Sprinkle the treatment agent evenly on the sawdust, mix evenly, treat and soften for 30-40 minutes, and then perform extrusion dehydration treatment;

[0009] Step 3: Add the antiseptic and anti-moth solution into the container, then add the squeezed and dehydrated sawdust into the container and soak for 40-60 minutes, then perform vacuuming operation, and take out the sawdust after vacuuming is completed;

[0010] Step 4: The soaked sawdust is subjected to secondary squeezing and dehydration to reduce the moisture content of the sawdust to 20-30%, and the moisture content of the sawdust is reduced to below 10% by natural air drying or heating and drying;

[0011] Step 5: Use a processing device to mix the sawdust with glue, lay it out in layers and level it. At the same time, heat the flame retardant liquid to 80-90°C, spray it on the laid sawdust layers in sequence, and then perform hot pressing to obtain an artificial particle board.

[0012] Preferably, when the sawdust is screened, unqualified sawdust and sawdust containing borers are separated, and oversized sawdust and debris are removed.

[0013] Preferably, the sawdust is sterilized by ultraviolet irradiation after screening, and the ultraviolet irradiation sterilization time is 10-20 minutes.

[0014] Preferably, the treatment agent comprises a mixture of one or more of sulfate, nitrate, phosphate, sodium salt and potassium salt.

[0015] Preferably, the antiseptic and anti-moth lotion comprises 50-60 parts of styrene acrylic emulsion, 20-30 parts of benzoic acid, 15-20 parts of boric acid and 5-10 parts of anti-moth essential oil.

[0017] Preferably, when vacuuming in step three, the pressure is adjusted to 0.08-1 MPa for 15-50 min, and then the pressure is adjusted to 0.01-0.02 MPa for 40-60 min, and this is a cycle, and the cycle period is 2-3 times.

[0018] Preferably, when the sawdust is laid out in layers and leveled, the coarse sawdust is first transported to the trough, and then the fine sawdust is laid on the coarse sawdust. After the laying is completed, the above steps are repeated again until the multi-layer laying of the particle board is completed.

[0019] Preferably, the flame retardant includes 10-20 parts of magnesium sulfate, 20-30 parts of magnesium chloride, 8-10 parts of talc, 15-20 parts of magnesium oxide, 5-10 parts of sodium dihydrogen phosphate, 20-30 parts of methyl cellulose, and the balance is water.

[0021] The manufacturing process of the anti-corrosion, anti-insect and flame-retardant particle board prepared by the present invention can soften the sawdust and squeeze out water by sprinkling the treatment agent on the sawdust, and soak the squeezed and dehydrated sawdust in anti-corrosion and anti-insect medicine, and then perform a vacuum operation to make the anti-corrosion and anti-insect medicine enter the sawdust more easily, thereby shortening the anti-corrosion and anti-insect treatment time and improving the anti-insect performance. At the same time, the moisture content will be greatly reduced after the secondary squeezing and dehydration, shortening the subsequent drying time and improving the production efficiency.

[0023] The present invention can stably control the quality of sawdust and effectively prevent corrosion and moths by screening sawdust and then sterilizing them with ultraviolet rays. The present invention can also spread and level the sawdust in layers after mixing with glue, and spray the flame retardant liquid on the spread sawdust layer by heating. The flame retardant liquid not only has a good flame retardant effect, but also forms an invisible protective layer when mixed with the sawdust particles. After high pressure and curing treatment, the particle board has stable structural strength and high mechanical properties, thereby improving the quality of the particle board. DETAILED DESCRIPTION

[0090] Comparative Example 2.

[0091] The difference from Example 3 is that no antiseptic and anti-moth liquid is added when manufacturing the particle board.

[0092] Comparative Example 3.

[0093] The difference from Example 3 is that no flame retardant liquid is added when manufacturing the particle board.

[0094] The products of Examples 1-3 and Comparative Examples 1-3 were subjected to performance tests;

[0095] 30 particle board samples were prepared and divided into 6 groups with 5 samples in each group. Each group corresponded to Examples 1-3 and Comparative Examples 1-3 and were numbered A / B / C / D / E / F. Finally, the particle board samples in groups A / B / C / D / E / F were tested respectively. The test results are shown in the following table.

[0096] Fire rating Compressive strength MPa Anti-insect performance A A 0.65 high B A 0.65 high C A 0.67 high D C 0.52 Low E A 0.58 Low F C 0.59 high

[0097] It can be seen from Examples 1-3 that the anti-corrosion, anti-insect and flame-retardant particle board manufacturing process made using the present invention has a stable structural strength, high mechanical properties, good flame retardant effect, and good anti-insect performance.

[0098] It can be seen from Example 3 and Comparative Example 3 that by heating the flame retardant liquid and spraying it on the flat sawdust layer, it not only has a good flame retardant effect, but also forms an invisible protective layer when mixed with the sawdust particles. After high pressure and curing treatment, the particle board has stable structural strength and high mechanical properties;

[0100] The innovation of the present invention is:

[0101] The present invention can soften and squeeze out the wood chips by sprinkling the treatment agent on the wood chips, and soak the squeezed and dehydrated wood chips in antiseptic and anti-insect medicine, and then perform a vacuum operation to make the antiseptic and anti-insect medicine enter the wood chips more easily, thereby shortening the antiseptic and anti-insect treatment time and improving the anti-insect performance. At the same time, after the secondary squeezing and dehydration, the moisture content will be greatly reduced, shortening the subsequent drying time and improving the production efficiency. After screening the wood chips and then sterilizing them with ultraviolet rays, the quality of the wood chips can be stably controlled, and antiseptic and anti-insect can be effectively performed. After the wood chips are mixed with glue and then laid out in layers and leveled, the flame retardant liquid is heated and sprayed on the laid wood chip layer, which not only has a good flame retardant effect, but also forms an invisible protective layer when mixed with wood chip particles. After high pressure and curing treatment, the structural strength of the particle board is stable, the mechanical properties are high, and the quality of the particle board is improved.
