Embodiment 1
[0013] A preparation method of insect-proof plywood, comprising insect-proof treatment of veneer and insect-proof treatment of glue, the thickness of the veneer is 1.2mm, and the water content is 11%;
[0014] The method of veneer anti-insect treatment is as follows: immerse the veneer in the treatment solution, each 100ml treatment solution contains 3g hydrogen peroxide and 1.2g alkone, immerse it under vacuum for 1.8 hours, then pressurize to 0.7MPa and keep it for 35 minutes, take it out and dry it When the moisture content is 6%, it can be processed in a fumigation and drying furnace for 28 minutes. The smoke material in the fumigation and drying furnace is paulownia wood after acid treatment;
[0015] The anti-insect treatment method of the adhesive is to add composite particles equivalent to 6% of its weight in the adhesive, and the preparation method of the composite particles is: alkone, carbon nanotubes and polyvinyl alcohol are mixed in a weight ratio of 5 : 9:1 mixi...
Embodiment 2
[0020] A preparation method of insect-proof plywood, comprising insect-proof treatment of veneer and insect-proof treatment of glue, the thickness of the veneer is 1.2mm, and the water content is 10%;
[0021] The method of veneer anti-insect treatment is: immerse the veneer in the treatment solution, each 100ml treatment solution contains 2g hydrogen peroxide and 1.5g alkone, soak for 1.5 hours under vacuum conditions, then pressurize to 0.6MPa for 30 minutes, take out and dry When the moisture content is 5%, it can be processed in a fumigation and drying furnace for 25 minutes. The smoke material in the fumigation and drying furnace is paulownia wood after acid treatment;
[0022] The anti-insect treatment method of the adhesive is to add composite particles equivalent to 4% of its weight in the adhesive, and the preparation method of the composite particles is: alkone, carbon nanotubes and polyvinyl alcohol are mixed in a weight ratio of 5 : 9:1 mixing, then ultrasonically ...
Embodiment 3
[0027] A preparation method of insect-proof plywood, comprising insect-proof treatment of veneer and insect-proof treatment of glue, the thickness of the veneer is 1.2mm, and the water content is 12%;
[0028] The method of veneer anti-insect treatment is: immerse the veneer in the treatment solution, each 100ml treatment solution contains 4g hydrogen peroxide, 0.7g alkone, soak for 2 hours under vacuum conditions, then pressurize to 0.8MPa for 40 minutes, take out and dry When the moisture content is 8%, it can be processed in a fumigation and drying furnace for 30 minutes. The smoke material in the fumigation and drying furnace is paulownia wood after acid treatment;
[0029] The anti-insect treatment method of the adhesive is to add composite particles equivalent to 7% of its weight in the adhesive, and the preparation method of the composite particles is: alkone, carbon nanotubes and polyvinyl alcohol are mixed in a weight ratio of 5 : 9:1 mixing, and then ultrasonically d...
