Non-formaldehyde waterproof plastic film reinforced flexible decorative veneer and preparation method thereof

Abstract

The invention discloses a non-formaldehyde waterproof plastic film reinforced flexible decorative veneer. Composting faces of a rotary cut or sliced decorative veneer and a plastic film are subjected to low-temperature plasma modification treatment, the treated composite faces of the decorative veneer and the plastic film are stacked to form composite blanks, and the non-formaldehyde waterproof plastic film reinforced flexible decorative veneer is obtained through hot-press gluing. The invention further discloses a preparation method of the non-formaldehyde waterproof plastic film reinforced flexible decorative veneer. The product prepared by adopting the method releases no formaldehyde, no adhesive or gluing procedure is omitted, the production cost is lowered, the product suppleness is good, and the non-formaldehyde waterproof plastic film reinforced flexible decorative veneer has the enough transverse tensile strength, will not cause glue penetration, is good in water resistance, saves energy, and is environmentally friendly, easy and convenient to operate and high in efficiency.

Description

technical field [0001] The invention relates to a preparation method of formaldehyde-free water-resistant enhanced decorative veneer, which belongs to the wood processing industry and is a new process adopted in the fields of decoration, wood products, furniture lines, and door and window plate decoration. Background technique [0002] my country is a big country in the manufacture of wood products. Among them, the production capacity and output value of wooden doors, wooden furniture and wooden floors rank first in the world. With the rapid development of the economy and the continuous improvement of material living standards, my country's furniture industry and interior decoration industry have shown a rapid growth trend in recent years, driving a large demand for wood decoration materials, and my country's timber resources are in short supply. According to the eighth national According to the survey of forest resources, my country currently has a forest area of ​​208 milli...

AI Technical Summary

Problems solved by technology

However, the adhesive used in the lamination of traditional non-woven fabrics or paper-based flexible decorative veneers usually contains formaldehyde and is not environmentally friendly, and the decorative veneer has poor water resistance, easy glue penetration, and complex finishing processes.

[0004] At present, since the plastic film and wood are polymer materials with different polarities, the interface adhesion of the plastic film substrate flexible decorative veneer made of the two composites is poor, and the plastic film is a thermoplastic material, and its melting temperature reaches 130°C. The hot-pressing temperature of plywood-grade other wood-based panels prepared by plastic film needs to reach 140-170°C, the hot-pressing time is generally more than 3 minutes, and the hot-pressing pressure is usually above 0.6MPa. The shrinkage coefficients of film and decorative veneer are different. Under high temperature and hot pressing conditions, the surface of flexible decorative veneer products can easily be curled, which is not conducive to industrial use, and the reduction of hot pressing time and hot pressing pressure will be more conducive to improving production efficiency.
