Problems solved by technology

[0005] At present, there is no literature report on the production of eucalyptus solid wood composite flooring with anti-corrosion composite urea-formaldehyde resin as glue
However, the whole eucalyptus solid wood composite floor is a wooden material, which is easily attacked by bacteria, insects, marine borers and other organisms, and is easy to rot. Therefore, the corrosion resistance of the whole eucalyptus solid wood composite floor is not high, and the insect resistance is poor. It is subject to some restrictions on the use

Embodiment 1

[0070] The method for producing full eucalyptus solid wood composite floor by adopting anticorrosion composite urea-formaldehyde resin comprises the following steps:

[0071] (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;

[0072] (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%;

[0073] (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 anti-corrosion compound urea-formaldehyde resin, and the amount of glue on one side is 200g / m 2 ;

[0074] (4) Three times of cold pressing: the eucalyptus slab is cold pressed t...

Abstract

The invention discloses a method for producing an all-eucalyptus solid wood composite floor by corrosion-resistance composite urea resins. The method comprises the steps of: board rotary slicing-veneer drying-gluing-three times of cold pressing-standing maintenance-three times of hot pressing-cooling maintenance-blank fixed-thickness sanding-substrate surface layer gluing-maintenance grooving-paint drying shaping. The key point of the method is to adopt melamine modified urea resins as a main material of adhesive; oxide starch is added as a viscous compounding agent; polyvinyl alcohol serves as a toughening agent; hydrogenated rosin serves as antioxidant; polyisocyanate serves as a curing agent; isobutyltriethoxysilane serves as a bridging agent; phenolated lignin serves as a formaldehyde capturing agent; and a preservative is added to prepare the corrosion-resistance composite urea resins; and the solid wood composite floor produced by the corrosion-resistance composite urea resins has the advantages of low formaldehyde residual volume and good corrosion resistance, is better in resistance on wood rotting fungus, mould and termites, and prolongs the service life of the all-eucalyptus solid wood composite floor.

Description

technical field [0001] The invention belongs to the field of artificial board manufacture, in particular to a method for producing whole eucalyptus solid wood composite floor by using anticorrosion 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 disadvantage of unidirecti...
