Geothermal type formaldehyde-removing solid wood composite floor and manufacturing method thereof

Abstract

The invention discloses a geothermal type formaldehyde-removing solid wood composite floor and manufacturing method thereof and aims to increase the formaldehyde removing effect of the composite floor. The composite floor comprises floor base material. Rabbets are formed in four sections of the floor base material. The floor base material sequentially comprises a filling layer, a paint-preventing layer, a primer layer and a finishing coat layer from bottom to top. A waterproof layer is disposed at the bottom of the floor base material. The composite floor is characterized in that the finishing coat layer sequentially comprises a wear-resistant finish coating layer, a scratch-resistant finishing coat layer and a formaldehyde-removing finishing coat layer from the bottom to top. Common environment-friendly UV coatings are used on the wear-resistant finish coating layer and the scratch-resistant finishing coat layer. The geothermal type formaldehyde-removing solid wood composite floor conforms to national standards, and product quality is increased greatly.

Description

technical field [0001] The invention relates to the field of floors, in particular to a geothermal formaldehyde-removing solid wood composite floor and a manufacturing method thereof. [0002] Background technique [0003] Solid wood composite flooring is made of cross-laminated boards of different tree species, which overcomes the disadvantage of unidirectional isotropy of solid wood flooring, has a small dry shrinkage and wet expansion rate, has good dimensional stability, and retains the natural wood grain and Comfortable foot feeling, solid wood composite flooring combines the stability of laminate flooring and the aesthetics of solid wood flooring, and has environmental protection advantages, and solid wood composite flooring not only has the advantages of ordinary solid wood flooring, but also effectively adjusts the internal stress between wood , Improve the disadvantage of large deformation of wood with seasonal changes in dryness and humidity, so it is loved by con...

The disadvantages of this method are: a. The elimination rate of formaldehyde in indoor air is low, and the lasting effect is short; b. The production process takes a long time, which is not suitable for rapid production on the assembly line; The color, texture, or pattern of the decorative material

The disadvantages of this method are: the formaldehyde elimination rate is low, the production process takes a long time, and it is not suitable for rapid production on the assembly line

Chinese utility model patent ZL 201220294494.5 discloses an aldehyde-removing floor. The aldehyde-removing floor is equipped with a nano-thermal conductive aldehyde-removing layer, and nano-graphite is used to remove aldehydes. The main mechanism is that nano-graphite has good adsorption properties, and nano-graphite will After formaldehyde is adsorbed, it is decomposed and cleared by the formaldehyde remover; however, the utility model patent does not disclose the composition of the formaldehyde remover and the decomposition mechanism of formaldehyde, and it is impossible to judge whether the product of the formaldehyde decomposed by the formaldehyde remover is harmful to the human body
