Problems solved by technology

The preparation method of the thin wood material is to complete the modeling, installation and laying first, and then use an electric iron (direct heating by utilizing the heat transfer properties of the material) or an electromagnetic heating tool (indirect heating through the magnetic conductive material) to compound the veneer on the base material. The material is easy to use, easy to maintain and replace. At the same time, the process of gluing, nail fixing and painting during construction is eliminated. There are no nail holes and paint surface defects caused by the construction environment on the veneer, and the construction environment is greatly improved. , reduce the impact of cross-operation, speed up the construction progress, make the decoration truly factory-like, and effectively avoid the pollution caused by interior decoration. However, because the adhesive used is hot-melt adhesive and heated by an electric iron, the heating area is small and the heating efficiency is low. Promotion Difficulty

Embodiment 1

[0066] 1. Cut the beech wood into 0.3mm veneer to make beech veneer material;

[0067] 2. Soak the beech veneer material in the BL-environmentally friendly flame retardant solution with a concentration of 30% by mass, keep the soaking temperature at 50°C, soak for 40 minutes, take it out to obtain soaked beech veneer, and then spread the soaked beech veneer, Drying treatment is carried out at a temperature of 25-30°C until the moisture content of the beech veneer is 14%, and the flame-retardant beech veneer 3 is obtained;

[0068] The prepared flame-retardant veneer has a moderate moisture content, so as to ensure that the composite veneer has good flexibility and will not crack when the wood is bent due to low moisture content. At the same time, it will not crack due to shrinkage of the veneer due to excessive moisture content after construction. The flame retardant used in the embodiment of the present invention selects BL-environmental protection flame retardant for use, ex...

Embodiment 2

[0080] 1. Cut the beech wood into 0.4mm veneer to make beech veneer material;

[0081] 2. Soak the beech veneer material in the BL-environmentally friendly flame retardant solution with a concentration of 40% by mass. Keep the soaking temperature at 40°C. After soaking for 30 minutes, take it out to obtain soaked beech veneer, and then spread the soaked beech veneer. Drying treatment is carried out at a temperature of 30-40°C until the moisture content of the beech veneer is 16%, and the flame-retardant beech veneer is obtained;

[0082] 3. Set two PTFE films 2 between the upper and lower hot-pressed steel plates 1 of the wood-based panel hot press, and then assemble the blanks between the upper and lower PTFE films 2 in the order from bottom to top , that is, place cotton mesh cloth, PES film and flame-retardant veneer 3 in sequence from bottom to top to form a blank to obtain a pre-pressed slab. The schematic diagram of flame-retardant decorative veneer assembly is as follow...

Embodiment 3

[0091] 1. Cut beech wood into 0.20mm veneer to make beech veneer material;

[0092]2. Soak the beech veneer material in the BL-environmentally friendly flame retardant solution with a concentration of 50% by mass, keep the soaking temperature at 70°C, soak for 20 minutes, take it out to obtain soaked beech veneer, and then spread the soaked beech veneer, Carry out drying treatment at a temperature of 20-25°C until the moisture content of the beech veneer is 15% to obtain a flame-retardant beech veneer;

[0093] 3. Set two PTFE films 2 between the upper and lower hot-pressed steel plates 1 of the wood-based panel hot press, and then assemble the blanks between the upper and lower PTFE films 2 in the order from bottom to top , that is, place cotton mesh cloth, PES film, and flame-retardant veneer 3 in sequence from bottom to top to prepare a pre-pressed slab. The schematic diagram of the flame-retardant decorative veneer assembly is as follows figure 1 As shown, the thickness o...

Abstract

The invention discloses a flame-retardant decorative veneer and a manufacturing method thereof. The flame-retardant decorative veneer is composed of a veneer layer, an adhesive layer and a base material layer. After flame-retardant processing, a precious natural veneer plain plate is compounded with flexible reinforced base materials, so that the flame-retardant flexible compound decorative veneer is manufactured, natural texture of the precious veneer is maintained, and good decoration and flame retarding performance is achieved. The manufactured flame-retardant decorative veneer is high in strength and good in toughness, and can be used as a decoration material for plane walls, curved walls and ceilings; after hot pressing, a PES adhesive film forms a layer of thin film between the veneer and the reinforced materials, a good water blocking performance is achieved, and the veneer is prevented from going mouldy and changing colors after being affected with damp.

Description

technical field [0001] The invention relates to a composite decorative veneer and a preparation method thereof, in particular to a flame-retardant flexible composite decorative veneer and a preparation method thereof, belonging to the wood processing industry. Background technique [0002] Decorative veneer is a surface decoration material whose thickness is generally less than 0.8mm after a certain treatment or processing, and then precision planed or rotary cut. It is characterized by natural texture or imitation natural texture, natural and generous style, and can be cut Cut and parquet. Decorative veneer has good bonding properties and can be pasted and decorated on most materials. It is an excellent decorative material for furniture, walls, floors, doors and windows, wood-based panels, and billboards. [0003] Decorative veneer can be divided into ordinary veneer and thin veneer according to the thickness. Wood, etc.; according to the pattern classification, it can be...
