Problems solved by technology

Therefore, the traditional process consumes a lot of energy and requires higher standards for the surface of the substrate
In addition, the environmental pollution is serious, the production cycle is very long, and the production cycle must be maintained for more than 3 days, and the production process will cause new internal stress on the substrate, which will affect the stability of the product during use.

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] The composite solid wood floor provided by the preferred embodiment of the present invention comprises a base material made of sawn wood, and a surface layer compounded on the base material by rolling and pressing. Since the base material used in the present invention is sawn timber, it can be used directly without the need for compacting and compacting, which reduces the production process of multi-layer compounding and three-layer compounding of floor base materials.

[0025] When the surface layer is combined with the base material, there is no need for a press, and the line pressure technology (that is, the rolli...

Abstract

The invention discloses a composite solid wood floor and a manufacturing process thereof. The composite solid wood floor comprises a base material made of a converted timber and a surface layer composited on the base layer through a rolling linear pressing method. Rolling linear pressing is implemented in a way that a modified polyurethane adhesive is reacted and cured under linear pressing, then the base material and the surface layer are adhered firmly and irreversibly and are permanently fixed, wherein the adhesive is prepared by adding a curing agent whose percentage composition is 3% and a propionic acid solvent whose percentage composition is 15% into the modified polyurethane. The composite solid wood floor is directly used without further assembly and lamination, the production process of compositing multiple layers or three layers of the base material of the floor is reduced, the surface layer and the base material are composited through the linear pressing technique at one time without a press, the hot pressing and cold pressing processes for the composition of the surface layer are also reduced, no other heat energy is needed, the technical standard for the surface of the base material is lowered, the production cost is also reduced, no stress is produced on the floor blank in the production process, no product maintenance is needed, and the production cycle is at least shortened by more than 3 days.

Description

technical field [0001] The invention relates to a floor and its manufacturing process, in particular to a composite solid wood floor and its manufacturing process. Background technique [0002] At present, two kinds of techniques are commonly used in the production of solid wood composite flooring, one is the hot pressing process, and the other is the cold pressing process. The process pressure parameters of these two processes are all above 8 kg per square centimeter, and the hot pressing also requires a temperature above 90°C. Therefore, the traditional process consumes a lot of energy and requires higher standards for the surface of the substrate. In addition, the environmental pollution is serious, the production cycle is very long, and the production cycle must be maintained for more than 3 days, and the production process will cause new internal stress on the substrate, which will affect the stability of the product during use. Contents of the invention [0003] Th...
