Production method of weather-proof multilayer composite wood floor

Abstract

The invention discloses a production method of weather-proof multilayer composite wood floor, comprising the following steps: after normal procedures of drying, balancing and nourishing life, the water content of a wood panel is lowered to 12-16% from originally more than 16%; after sawn into face veneers with thickness being 1-4mm, the water content of the wood panel is lowered to 6-9% by low temperature drying, balancing and nourishing life; then the water content of plywood basal material with water content being 9-14% is lowered to 10-8% by lower temperature drying, balancing and nourishing life; then, plywood basal material which conforms to water content requirement is cut, sanded and glued to assemble with the face veneers, and hot-pressing or cold-pressing procedure is adopted to glue into a floor blank; and finally, the floor blank is nourished, processed with a mortise and decorated by painting on the surface so as to form the weather-proof multilayer composite wood floor. The multilayer composite wood floor produced with the method has small warping degree and deformation ratio when used, has small possibility of cracking, has strong weather-proof performance and can be used as heating wood floor.

Description

technical field [0001] The invention relates to a production method of a floor, in particular to a production method of a weather-resistant multilayer composite wood floor. Background technique [0002] Existing floor mainly contains three kinds: solid wood floor, multi-layer composite wood floor and reinforced composite floor. Among them, solid wood flooring has high requirements on the quality of materials, and its thickness must be guaranteed to be above 10-20mm. In addition, solid wood is expensive, easy to deform, and poor in stability, so it is difficult to meet the requirements of consumers; Layer and decorative layer, the surface strength is high, wear-resistant, burn-resistant, and weather-resistant. However, because the base layer is generally made of wood chips or wood bran mixed with glue, its water resistance is poor and it is easy to deform. It is only suitable for In dry areas, there are certain limitations in use; while the multi-layer composite wood floor i...

Among them, solid wood flooring has high requirements on the quality of materials, and its thickness must be guaranteed to be above 10-20mm. In addition, solid wood is expensive, easy to deform, and poor in stability, so it is difficult to meet the requirements of consumers; Layer and decorative layer, the surface strength is high, wear-resistant, burn-resistant, and weather-resistant. However, because the base layer is generally made of wood chips or wood bran mixed with glue, its water resistance is poor and it is easy to deform. It is only suitable for In dry areas, there are certain limitations in use; while the multi-layer composite wood floor is made of a solid wood surface board on the multi-layer plywood base material. Although the existing multi-layer composite wood floor has good stability and water absorption It is better than the first two, but its production is to directly dry the solid wood surface board in a drying kiln with a dry bulb temperature of 60-100 degrees to a moisture content lower than that required by the pressed slab, and then saw and process it into a single The base material is also directly used without drying and balanced health, and then pressed into a slab to form

Since the solid wood surface board is directly dried to a moisture content below the requirement of the pressed slab, the drying stress of the surface board is relatively large, and it is easy to crack, especially for tree species with high density. The pressing process is also prone to a large amount of warping deformation, which is difficult to control, resulting in Difficult to produce and troublesome to handle, waste a lot of adhesive, material, energy and manpower

Due to the technical defects of the existing processing methods, the weather resistance is poor, and it is not suitable for use as a floor heating floor
