Problems solved by technology

[0006] In view of the above-mentioned technical defects, the purpose of the present invention is to provide a method for producing eucalyptus solid wood composite flooring by using insect-proof and mildew-proof composite urea-formaldehyde resin, so as to solve the problem that the current eucalyptus solid wood composite flooring is deformed due to air humidity, and even moldy, Corrosion and other situations lead to severe moldy smell in the room, and after long-term moisture absorption, the board will warp and deform due to the difference in expansion force

Embodiment 1

[0072] The method for producing full eucalyptus solid wood composite flooring by adopting insect-proof and mildew-proof composite urea-formaldehyde resin comprises the following steps:

[0073] (1) Rotary slices: use a rotary cutter to cut the eucalyptus into 1.5-3 mm thick slices to obtain eucalyptus veneers, and pick out the unqualified boards with insect eyes, decay and excessive defects;

[0074] (2) Veneer drying: Dry the eucalyptus veneer with a hot air stove, and control the moisture content of the veneer to be less than or equal to 10%;

[0075] (3) Glue application: use a glue applicator to apply glue to the eucalyptus veneers and arrange 8-10 layers of glued eucalyptus veneers in criss-cross layers according to the wood texture structure, and glue them together to get the eucalyptus planks Blank; the glue is insect-proof and mildew-proof compound urea-formaldehyde resin, and the amount of glue on one side is 200g / m 2 ;

[0076] (4) Three times of cold pressing: the...

Abstract

A method for producing whole eucalyptus parquet from anti-insect and anti-mildew composite urea-formaldehyde resin comprises steps as follows: rotary cutting of a board to form pieces; single plate drying; adhesive coating; three times of cold pressing; leaving to stand for reconditioning; three times of hot pressing; heat dissipation for reconditioning; fixed-thickness sanding of plate blanks; adhesive coating of base material surface layers; reconditioning and grooving; paint coating, drying and setting. The key of the production method is that melamine modified urea-formaldehyde resin is used as a main adhesive material; oxidized starch is added as a viscous compound; polyvinyl alcohol is added as a toughening agent; hydrogenated rosin is added as an anti-oxidant; polyisocyanate is added as a curing agent; isobutyltriethoxysilane is added as a bridging agent; phenolated lignin is added as a formaldehyde catching agent; an anti-insect and anti-mildew agent is added; anti-insect and anti-mildew composite urea-formaldehyde resin is prepared; and the parquet prepared from anti-insect and anti-mildew composite urea-formaldehyde resin has the advantages of being low in formaldehyde residual amount and good in anti-insect and anti-mildew effect, has the relatively high inhibition effect on breeding of Aspergillus, Trichoderma and Penicillium and has the instant killing force and the long-acting preventive effect on board powder-pest beetles.

Description

technical field [0001] The invention belongs to the field of artificial board manufacturing, in particular to a method for producing whole eucalyptus solid wood composite flooring by using an insect-proof and mildew-proof composite urea-formaldehyde resin. Background technique [0002] With the development of China's economy and the improvement of people's living standards, the requirements for home decoration are also constantly increasing. Because of its natural and beautiful texture and good texture, wooden floor has become the first choice material for home floor decoration. Solid wood composite flooring overcomes the shortcomings of solid wood flooring swelling and shrinking, has good dimensional stability, and at the same time retains the natural wood grain and comfortable foot feeling of solid wood flooring, thus becoming an important variety in flooring. Solid wood composite flooring is made of cross-laminated boards of different tree species, which overcomes the di...
