[0002] In the prior art, the solid wood composite floor substrate produced by using eucalyptus and poplar or birch and poplar, because the densities of birch and eucalyptus are less than 0.65g / cm 3 , whether it is to transfer wood grain on its surface combined with UV paint treatment, or to combine real wood veneer paper with UV paint treatment, it is difficult to change the defects of its low surface hardness and difficulty in quickly pressing and pasting melamine paper

Embodiment Construction

[0007] see attached figure 1 , A surface crust hardening plywood disclosed by the present invention is characterized in that: the surface of the plywood A is infiltrated with a glue depth of 0.5 to 4 mm, and is subjected to low temperature drying and hot pressing again to cure to form a skin hardening layer B on the surface, In this way, a surface-crusted hardened plywood whose surface hardness is higher than the wood hardness of the plywood itself is made.

[0008] And the surface crust hardening plywood disclosed by the present invention has the advanced nature and practicability in that the hardness of the surface of the plywood is improved by infiltration and skinning, and the surface layer decoration is carried out by transferring wood grain or pressing real veneer paper and combining with UV paint. During processing, not only the impact strength of the surface layer of the substrate is improved, but also dry flowers will not appear when the melamine paper is quickly pres...

Abstract

The invention discloses a surface crust hardened plywood, which belongs to the technical field of artificial board processing. It is characterized in that: the depth of glue penetration on the surface of the plywood is 0.5 to 4 mm, and after low-temperature drying and heat-pressing curing treatment again, a crust hardening layer is formed on the surface, so as to make a kind of surface hardness higher than the wood hardness of the plywood itself. Surface crust hardened plywood. Its advancement and practicability lie in the fact that the hardness of the plywood surface is increased through glue penetration, and when the wood grain is transferred or the real wood veneer paper is combined with UV paint for surface decoration, it not only improves the impact resistance of the substrate surface Strength, and there will be no dry flowers when the melamine is quickly pressed, thus improving the quality of the plywood.

Description

technical field [0001] The invention discloses a surface-crusted hardened plywood, which belongs to the technical field of wood-based panel processing. Background technique [0002] In the prior art, the base material of solid wood composite floor produced by using eucalyptus and poplar or birch and poplar, because the density of birch and eucalyptus is less than 0.65g / cm 3 , whether it is transfer wood grain on its surface combined with UV paint treatment, or pressing real veneer paper combined with UV paint treatment, it is difficult to change its low surface hardness and it is difficult to achieve rapid pressing and pasting of melamine paper. SUMMARY OF THE INVENTION [0003] The invention discloses a surface-crusted hardened plywood, the purpose of which is to infiltrate the surface of the plywood to a depth of 0.5 to 4 mm, and then dry it at a low temperature and then heat-press and cure it again to form a crusted hardened layer on the surface. A surface-crust harden...
