A kind of processing method of high-quality bamboo flat floor

Abstract

The invention relates to a processing method for high-quality bamboo flattened floor. The processing method comprises the steps of selecting materials and splitting, pre-forming concave slots, cooking and softening, flattening at a high temperature, drying, processing comb teeth, preparing substrate, gluing, transversely reinforcing and the like. The bamboo floor has density which is only 0.6g / cm<3> (optimum density of produced floor), has surface-layer density and core-layer density which are in step distribution, has relatively good elasticity and keeps natural textures of a high-hardness bamboo green surface. Besides, the high-quality bamboo flattened floor can be mounted in a staggered mode on the scene, and floor units are mutually clamped, so that the floor has higher integral stability. The high-quality bamboo flattened floor has the advantages of being not liable to crack, high in surface hardness and good in wear resistance, simple in process, and the like, and is novel high=quality floor with excellent physical property and excellent mechanical property.

Description

(1) Technical field [0001] The invention relates to a processing method for a high-quality bamboo flattened floor. (2) Background technology [0002] my country is the country with the richest bamboo resources in the world. According to the statistics of the Eighth National Forest Resources Inventory (2009-2013), the current bamboo forest area in the country is 6.7 million hm 2 Among them, moso bamboo forest accounts for 70%, 30% of the world's total, and about 3% of the national forest area. Bamboo has a short growth cycle and can be felled in 3 to 5 years. It has the advantages of good toughness and high hardness. Bamboo flooring has natural resource advantages in replacing wooden floors and marble and other flooring materials. [0003] my country's bamboo flooring has a production history of more than 20 years, but more than 90% of it is mainly exported, and it has been difficult to obtain the approval of the domestic market. This has a lot to do with the production proc...

AI Technical Summary

Problems solved by technology

The production of these two floors has applied a large amount of industrial adhesives, resulting in the release of harmful substances such as formaldehyde

Bamboo flooring is prone to quality problems such as cracking of the glue layer during use, especially in my country's relatively wide area, where the difference in equilibrium moisture content between regions increases, and the dimensional stability is difficult to control

The bamboo utilization rate of ordinary bamboo flooring is only 50%, although the bamboo utilization rate of the latest technology recombined bamboo can reach more than 90%, but its density must reach 1g / cm 3 In order to get better gluing, such a large hardness as an indoor floor is uncomfortable for the feet, and the second is the loss of the real texture of bamboo
