Anti-damp floor and manufacturing method thereof

Abstract

The invention discloses an anti-damp floor and a manufacturing method thereof. The anti-damp floor comprises a wear-resistant layer with a protection function, a decoration layer with an attractive function, a base material layer with a supporting function and a balance layer with an anti-damp and anti-deformation function from top to bottom in sequence. The wear-resistant layer is a transparent oil paint layer containing nano aluminum oxide with the mass fraction of 1-5%; the decoration layer is made of PVC colored film paper; the decoration layer and the base material layer are glued throughbi-component polyurethane resin glue, and a waterproof layer made of thermoplastic resin glue is further arranged between the base material layer and the balance layer. Compared with an existing anti-damp floor, the anti-damp floor has excellent wear resistance and waterproof and dampproof performance, the manufacturing method is simple, economical and practical, the flatness is good, and the aimof environmental protection is achieved; in addition, according to different kinds of added additives, the dampproof floor has multiple additional functions such as mold prevention, sterilization, oxidation resistance and odor removal and has high practical value.

Description

technical field [0001] The invention relates to the field of composite floors for building decoration, in particular to a moisture-proof floor and a manufacturing method thereof. technical background [0002] Traditional solid wood composite flooring is made of cross-laminated boards of different tree species. Due to the anisotropy of the wood itself, when the external environment (temperature, humidity, etc.) changes, it will cause changes in the moisture content of the wood, causing the wood to shrink and expand when wet. , warping and deformation, etc., and cannot be repaired after water damage, the foot comfort is reduced, which seriously affects the comfort and aesthetics of the floor; in addition, the solid wood composite floor has poor wear resistance, more complex structure, and poor dimensional stability of the floor. At present, the general moisture-proof floor on the market only lays a moisture-proof layer on the surface of the floor to isolate the moisture above ...

[0002] Traditional solid wood composite flooring is made of cross-laminated boards of different tree species. Due to the anisotropy of the wood itself, when the external environment (temperature, humidity, etc.) changes, it will cause changes in the moisture content of the wood, causing the wood to shrink and expand when wet. , warping and deformation, etc., and cannot be repaired after water damage, the foot comfort is reduced, which seriously affects the comfort and aesthetics of the floor; in addition, the solid wood composite floor has poor wear resistance, complex structure, and poor dimensional stability of the floor

At present, the general moisture-proof floor on the market only lays a moisture-proof layer on the surface of the floor to isolate the moisture above the floor, while ignoring the change of moisture content at the bottom of the floor, so that the wooden floor will still cause warping and deformation after being damp.

[0003] On January 22, 2014, the Chinese invention patent with the publication number CN103526910A discloses a composite floor, which consists of a surface layer, a decorative layer, a base material layer and a bottom layer from top to bottom, and a waterproof layer is added to the bottom layer. Although it can achieve moisture-proof effect, the process is cumbersome and the cost of materials increases
