Problems solved by technology

[0005] In actual production, the stability of traditional biomass-based adhesives during application and storage is relatively poor compared with chemical adhesives, and the natural characteristics of biomass make their stability relatively poor
There are still a series of unstable factors in the prior art method, so the present invention proposes a formaldehyde-free multi-layer solid wood composite floor and its production process, by adjusting the process parameters (temperature , time and pressure), resulting in formaldehyde-free multi-layer parquet

Embodiment 1

[0025] Take the product of 1.2mm oak veneer as an example. The veneer and the base material of corresponding specifications are glued, veneered, cold pressed for 50-60 minutes, (hot pressed) and then balanced for health. After 80-85 hours, the raw material is cut and sanded to form a plain board. Then carry out forming and groove processing. After that, the primer and topcoat are applied; finally, the finished product is packaged and rolled off the assembly line.

Embodiment 2

[0027] Take the product of 1.2mm oak veneer as an example. The wood veneer and the base material of corresponding specifications are adjusted, and the ratio of glue to curing agent is about 100: (10-20); then glue is applied, one side is glued, and the amount of glue applied is about 140-160g / m2 by roller coating 2 , Then after veneering, cold pressing, (hot pressing) and rebalancing health preservation, after 80-85 hours, it will be cut and sanded to form a plain board. Then carry out forming and groove processing. After that, the primer and topcoat are applied; finally, the finished product is packaged and rolled off the assembly line.

Embodiment 3

[0029] Take the product of 1.2mm oak veneer as an example. The veneer and the base material of the corresponding specifications, after the glue adjustment and glue application process, adopt artificial veneer, and the veneer after strict sorting, go through the cutting process, cut it into the required specifications, and use manual pushing The method is to paste it on the surface of the glued substrate, cold press for 50-60 minutes, (hot press) and then balance the health. After 80-85 hours, it will be cut and sanded to form a plain board. Then carry out forming and groove processing. After that, the primer and topcoat are applied; finally, the finished product is packaged and rolled off the assembly line.

Abstract

The invention belongs to the technical field of building materials, and relates to a production process for a formaldehyde-free multi-layer solid-wood composite floor. The production process for the formaldehyde-free multi-layer solid-wood composite floor comprises the working procedures of gluing and veneering, cold-pressing, hot-pressing or curing, cutting, priming paint coating, forming, finishing paint coating, and packaging and finished product obtaining, wherein in the working procedure of gluing and veneering, the surface of a criss-cross multi-layer plate base material is coated with awater-based styrene-butadiene rubber emulsion, a single-side gluing amount is 100-200 g/m <2>, and a layer of hard broad-leaved wood veneer/wood skin with a thickness of 0.6-1.2 mm is pasted after gluing. According to the invention, by adjusting and optimizing the technological parameters, the formaldehyde-free multi-layer solid-wood composite floor with the physical and mechanical properties meeting the requirements of various indexes is prepared. The production process is simple, easy to operate and low in cost, and the characteristics of being aldehyde-free, green and environment-friendlyare met; and the stability, water resistance, impregnation peeling performance and other performance of the prepared formaldehyde-free multi-layer solid-wood composite floor reach the standard, the formaldehyde release amount is lower than 0.03 mg/m <3>, the standard requirements of 'aldehyde-free artificial plates and products thereof' are met, and other harmful organic volatile matters are avoided, so that the requirements of being green and environment-friendly are met.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a solid wood composite floor, in particular to a production process of an aldehyde-free multi-layer solid wood composite floor and the floor thereof. Background technique [0002] Multi-layer solid wood composite flooring uses natural precious tree veneers (veneer) of different thicknesses as the surface layer, and multi-layer boards made of solid wood veneers with criss-cross textures as the base material, coated with high performance, high wear resistance, and high environmental protection It is made of special UV curing floor paint, which is widely used in the home building materials industry. [0003] With the changes in the structure of wood raw materials, the progress of production technology and the improvement of environmental protection requirements, the wood processing industry has put forward higher requirements for multi-layer solid wood composite floors.
