Problems solved by technology

At present, the treatment method for cork decorative materials in our country is to primary crush the whole oak bark after stripping, and crush it into particles with a size of 2 to 5 cm, and then carry out secondary crushing of the large particles, and then enter the cone mill for processing into various The largest material is 4-6 mesh, and the smallest is 40-60 mesh. The mixture of various purposes is screened and air-selected, and the sand inside the material cannot be removed. Using the above raw materials to process cork, the fault area Small, destroys the natural pattern of oak bark, and can only produce low-grade cork products or cork substrates
Because the surface of the raw material treated by this method is a small granular structure, the aesthetic effect cannot be achieved, and it cannot be used as a decorative material, which limits the development of cork decorative materials in China and makes the use of valuable cork resources cheap.

Embodiment 1

[0027] Classify the peeled oak bark to separate thin bark and thick bark; remove the black bark and impurities on the surface of the selected oak bark with a wire brush, wire brush grinder, angle grinder, and electric planer, and process the raw materials from the beginning processing to improve the quality of the product; process the oak bark with less sand inclusion after removing the black skin and impurities, and process it with a pulverizer, screen out a material with a length of 20cm, and use it directly as a raw material; this material has a large and thick area, and will be processed in the future The wood grains on the faults are obviously connected to each other, forming irregular pictures and patterns, and can process products with beautiful patterns; in order to increase the softness of the material, the raw materials can be steamed in a steaming ball for 2 hours, and the temperature is controlled at 130°C , dry the steamed raw materials; then add 15% adhesive to th...

Embodiment 2

[0029] Classify the oak bark to separate the thin bark and thick bark; use a wire brush, a wire brush grinder, an angle grinder, or an electric plane to remove the black bark and impurities on the surface of the selected oak bark to improve the quality of the product; remove the black bark , Impurities containing less sand inclusions are processed by a pulverizer into a material with a length of 10cm, which is directly used as a raw material. The area of ​​this material is large and thick. In the future, the wood grains on the faults of the processed products will be obviously connected to each other, and irregular pictures and patterns will be formed, and products with beautiful patterns can be processed; in order to increase the softness of the material, the raw materials are boiled in a metal vessel for 6 hour, control the temperature at 90°C, and dry the boiled raw materials; then add 20% of the adhesive to the raw materials and stir in the mixer until the raw materials and...

Embodiment 3

[0031] Classify the peeled oak bark to separate thin bark and thick bark; remove the black bark and impurities on the surface of the selected oak bark with a wire brush, wire brush grinder, angle grinder, and electric planer; remove black bark and impurities Finally, the oak bark with less sand content is processed into a sheet material with a thickness of 0.2 cm by a powder cutter, which is directly used as a raw material. The sheet material is an irregular sheet polygon, which can be used as a high-density product, with no gaps, good fault wood grain, and various patterns can be processed; in order to increase the softness of the material, the sheet material is boiled in a metal vessel For 2 hours, control the temperature at 100°C, and dry the boiled raw materials; then add 17% binder to the raw materials and stir in a mixer until the raw materials and the binder are completely fused together; the stirred The raw materials are loaded into the mold and molded, the density is ...

Abstract

During compounding soft wood decorating material, surface back bark and impurity are eliminated before producing material. Material with more embedded sand is mixed with resin glue and the mixture is molded, the molded mixture is cut into sheets. When better flexibility is needed, the material is steamed or boiled, and then mixed with adhesive. The mixture is molded to produce blank and the blank is cut into surface material. The surface material is adhered to substrate material for compounding, and compounded material is ground in a grinder and waxed. The technological process of the present invention can produce soft wood decorating material with clear wood grain pattern, less embedded sand, smooth and soft surface.

Description

1. Technical field [0001] The invention relates to a treatment process of wood decorative materials, in particular to a composite process of cork decorative materials. 2. Background technology [0002] Cork decorative materials are processed from oak bark. Our country is a wild oak tree, which is mainly distributed in the mountains of Sichuan, Hubei, Shaanxi, Gansu, Henan and other places. It is artificially planted abroad, and the skin is picked and peeled every nine years. The section of oak bark is composed of cork parenchyma cells arranged in a hexagonal honeycomb shape, the cells are filled with air, and the main component of the cell wall is suberin, which is a polyester of hydroxy acid and phenolic acid, with similar chemical properties Stablize. Because of this special cell structure and chemical composition, cork products have unique properties, such as sound absorption, fire prevention, anti-slip, anti-pollution, anti-moth, anti-static, heat insulation, insulatio...
