Problems solved by technology

[0003] In the indoor environment, the existing wooden flooring uses a large amount of solid wood in order to pursue texture and foot feeling, which has a great impact on the ecological environment. Moreover, the price of solid wood flooring is high, and the maintenance cost in the later period is also high. Most of the imitation solid wood floors on the market For plywood, excessive formaldehyde release poses a threat to the health of users. It is urgent to find a composite wood floor that can replace solid wood floor, high quality, high price, healthy and environmentally friendly, and easy to maintain.

Abstract

The invention provides a biomass composite gluing veneer floor technology and a composite floor, a used base material. The base material is a polyolefin basic level with 1%-60% of biomass. The technology includes the following steps: the veneer is glued onto the polyolefin basic level through polyurethane glue, and press fitting is carried out for 8-15 hours at normal temperature after gluing; aconnecting part is machined at the side of the obtained product; the composite floor is obtained. According to the invention, the polyolefin basic level with biomass is used for replacing solid wood core layer, only veneer is adopted for the surface layer, a plenty of wood is saved, cutting of wood is reduced, and resources are protected; only the 2-layer gluing structure is adopted for the composite floor, and the entire floor is not easy to deform without the balance layer; as the polyolefin basic level has a plenty of biomass close to the property of the solid wood veneer, the linear expansion coefficient is consistent with the veneer, and the entire floor is not easy to cause buckling deformation after gluing, and compared with the other composite floors, the balance layer is not needed.

Description

technical field [0001] The invention relates to the field of flooring, in particular to a process for laminating a wood veneer floor with a biomass composite material, a composite floor, and a used base material. Background technique [0002] Floor, that is, the surface layer of the ground or floor of a building. Made of wood or other materials, there are many classifications of floors. According to the structure, they are: solid wood flooring, laminated wood flooring, three-layer solid wood composite flooring, bamboo wood flooring, anti-corrosion flooring, cork flooring and the most popular multi-layer solid wood flooring. Composite floors, etc.; classified by use: household, commercial, anti-static floors, outdoor floors, special floors for stage dance, special floors for sports halls, special floors for track and field, etc. [0003] In the indoor environment, the existing wooden flooring uses a large amount of solid wood in order to pursue texture and foot feeling, whic...
