Embodiment 1

[0045] Surface plate processing → core plate processing → bottom plate processing → glue lamination → finishing → surface coating → finished product;

[0046] Surface panel processing: use walnut wood as the surface panel, place it in a drying kiln for drying, and then send it to the balance warehouse for conditioning under constant temperature and humidity conditions, then use a four-sided planer to plan, and double-end milling to determine the length of the truncated section. For the right angle of the board, the multi-blade saw divides the board into 4 pieces, and then sorts and splices the board. The board is required to be flat, free of decay, insect holes, cracks, and dead joints. The thickness of the board is 4mm, and the moisture content of the board is 6%;

[0047] Core board processing: use fast-growing fir as the core board, place it in a drying kiln for drying, and then send it to the balance warehouse for conditioning under constant temperature and humidity conditi...

Embodiment 2

[0054] The thickness of the surface plate is 2mm, the thickness of the core plate is 8mm, and the thickness of the base plate is 2mm; the moisture content of the surface plate is 8%, the moisture content of the core plate is 8%, and the moisture content of the base plate is 7%; the UV primer and The paint quantity of UV topcoat is 60g / m 2 ; The described formaldehyde removal agent UV wear-resistant topcoat is 6g nanometer TiO 2 / Diatomaceous earth composite catalyst / 1000g top coat, nano TiO 2 / diatomite composite catalyst is the formaldehyde removal agent, and other steps are the same as in Example 1.

Embodiment 3

[0056] The moisture content of the surface plate is 7%, the moisture content of the core plate is 7%, and the moisture content of the bottom plate is 6%; the paint quantity of the UV primer and UV topcoat is 80g / m 2 ; The described formaldehyde removal agent UV wear-resistant topcoat is 12g nanometer TiO 2 / Diatomaceous earth composite catalyst / 1000g top coat, nano TiO 2 / diatomite composite catalyst is the formaldehyde removal agent, and other steps are the same as in Example 1.

[0057] Nano-TiO 2 / Diatomite composite catalyst, nano-TiO loaded with diatomaceous earth 2 Material, the surface of diatomaceous earth is evenly loaded with nano-TiO with crystal form of anatase 2 Particles; TiO 2 The grain size is about 12nm; TiO 2 The particles are closely combined with diatomaceous earth; TiO 2 The thickness of the cladding layer is 200nm~300nm; TiO 2 The loading amount is 15%-60% of the mass of diatomite.

Abstract

The invention relates to a process for producing formaldehyde-removing solid wood flooring. The process comprises the following steps of: processing a surface board, processing a core board, processing a base board, glue pressing and compounding, fine processing, coating the surface, and forming the finished product. The process has the advantages of strong natural visual sensation, comfortable foot sensation, good material quality, easy processing, cyclic utilization, good geothermy adaptability, strong stability, more simple and convenient construction and installation, excellent environmental performance, great increase of comprehensive utilization ratio of timbers and special effects on adsorbing and degrading free formaldehyde in indoor air.

Description

technical field [0001] The invention relates to a production process of a solid wood composite floor, in particular to a production process of a formaldehyde-removing solid wood composite floor. Background technique [0002] Solid wood composite flooring is made of cross-laminated boards of different tree species, which overcomes the disadvantage of unidirectional isotropy of solid wood flooring, has a small dry shrinkage and wet expansion rate, has good dimensional stability, and retains the natural wood grain and Comfortable foot feeling, solid wood composite flooring combines the stability of laminate flooring and the aesthetics of solid wood flooring, and has environmental protection advantages, and solid wood composite flooring not only has the advantages of ordinary solid wood flooring, but also effectively adjusts the internal stress between wood , Improve the disadvantage of large deformation of wood with seasonal changes in dryness and humidity, so it is loved by co...
