Composite material of mixed and knitted chemical fibers and natural veneers and preparation method of composite material

Abstract

The invention discloses a composite material of mixed and knitted chemical fibers and natural veneers and a preparation method of the composite material. The composite material is formed by knitting composite materials (1) comprising chemical fibers and wood fibers or knitting the composite materials (1) comprising the chemical fibers and the wood fibers with chemical fibers (2), and the composite materials (1) are formed by compounding and knitting the surface layers of the wood fibers with the bottom layers of the chemical fibers of presoaked resin, or the surface layers of the glass fibers of the presoaked resin with the bottom layers of the wood fibers. According to the composite material provided by the invention, the surface layer has the appearance and texture of natural wood fibers, high requirement standards can be met, and carbon fibers are compounded and knitted to form the composite material; the whole composite material is superior in properties such as tensile strength, elastic modulus, hardness, impact resistance and natural wood texture, and can be widely used for preparing electric appliance shells, furniture and building materials and the like. The preparation method provided by the invention is reasonable in process and high in product qualification rate, and can achieve large-scale industrialization production.

Description

technical field [0001] The invention relates to a novel composite material product, in particular to a composite material mixed with chemical fiber and natural wood veneer, its preparation method and its application in the preparation of electric appliance shells, furniture materials and vehicle interior decoration. Background technique [0002] Existing wood products are cut down trees, processed into boards, and then made into various wood products. The main defects of existing wood products are: felling trees has a huge impact on the environment, cumbersome processing and molding steps, poor mechanical properties, bulky, and limited molding technology It is highly resistant and flammable; in addition, the existing surface is pasted with wood grain decorative boards, and wood grains are pasted on ordinary wood boards. After being exposed to moisture and heat, it is easy to deform and fall off. In order to ensure sufficient strength, it must be made very thick, and the weigh...

[0002] Existing wood products are cut down trees, processed into boards, and then made into various wood products. The main defects of existing wood products are: felling trees has a huge impact on the environment, cumbersome processing and molding steps, poor mechanical properties, bulky, and limited molding technology It is highly resistant and flammable; in addition, the existing surface is pasted with wood grain decorative boards, and wood grains are pasted on ordinary wood boards. After being exposed to moisture and heat, it is easy to deform and fall off. In order to ensure sufficient strength, it must be made very thick, and the weight increases. Cutting and assembly must be used in the process, which is complicated and cumbersome

As a result, the product is single and has poor scratch resistance and no repairability. After the surface of the carbon fiber product is worn and scratched, it is easy to polish the fiber. The chemical fiber does not have polishing properties. Once the chemical fiber is worn, the entire product will be scrapped. Product standards that cannot meet the requirements of composite material products such as light weight, high strength, beautiful appearance, wood grain texture, and recovery
