Manufacturing method of composite floor with low-light super simulation surface layer

Abstract

The invention discloses a manufacturing method of composite floor with a low-light super simulation surface layer. By the use of a low-brightness steel plate, low-light decorative paper is compacted on a density board under a certain pressure and temperature to form the composite floor, wherein the pressure is 18-22MPa and the temperature is 190-220 DEG C. The compacted composite floor is preserved for 3-6 days. According to the method, the technology is simple to operate, wood effect of the manufactured floor is strong, and its luminosity reaches 5-20 degrees.

Description

technical field [0001] The invention relates to the technical field of floor manufacturing methods, in particular to a manufacturing method of a composite floor with a low-gloss super-imitation surface layer. Background technique [0002] Laminate flooring has entered the Chinese market for nearly 20 years. Due to its strong wear resistance, relatively low production cost, easy cleaning and many other advantages, it has been welcomed by consumers. Compared with the effect of solid wood flooring, the solid wood effect of high-gloss laminate flooring on the market has a certain gap, while the solid wood effect of low-gloss laminate flooring is closer to the effect of solid wood flooring. However, the existing low-brightness laminate flooring production process is relatively complicated. Generally, the impregnated wear-resistant paper layer, decorative paper layer, base material layer, and balance layer are integrally hot-pressed and composited. The limitation of the perspecti...

Problems solved by technology

However, the existing low-brightness laminate flooring production process is relatively complicated. Generally, the impregnated wear-resistant paper layer, decorative paper layer, base material layer, and balance layer are integrally hot-pressed and composited. The limitation of the perspective effect of the decorative paper layer makes the texture visual effect of the decorative paper design of the decorative board blurred

For example, the Chinese patent document CN1912246A has announced the invention of a "decorative paper with its own wear resistance", which is a method of dipping and drying once, and then spraying aluminum oxide particles by an air pump and then dipping and drying. Manufactured decorative paper, this method improves the clarity of the decorative paper, but due to drying and then spraying and dipping, the sprayed particles are likely to be uneven or fall off, and the clear effect of the decorative layer produced by the subsequent process is not obvious enough

Another example is the Chinese patent document CN101158217A, which discloses a "composite floor surface layer, composite floor and manufacturing method thereof", which proposes a preparation method for a composite floor. First, the decorative paper printed with texture effects is immersed in the first resin glue tank. , and then sprinkle aluminum oxide particles on the front of the impregnated decorative layer from the lower sander and immerse in the first dryer to dry, and then attach the wood fiber paper impregnated with resin glue to the decorative paper with aluminum oxide On top of that, the glue is soaked twice and then dried, and then combined with the substrate layer by hot pressing. This process is complicated to operate, and after compounding, the texture is blurred due to the wood fiber paper attached to the surface.

[0003] Therefore, the production method of laminate flooring in the prior art cannot produce low-light effect and laminated flooring with a super-imitation surface layer, and cannot meet the preference needs of the public for the solid wood effect of laminated flooring
