Production process and preparation method of wood-plastic product with natural wood grains on whole body

Abstract

The invention relates to a production process and a preparation method of a wood-plastic product with natural wood grains on the whole body. The production process and preparation method are mainly characterized by comprising the steps of firstly, preparing various wood-plastic particles with single colors and different fluidities; then, uniformly mixing the wood-plastic particles with the colors in proportion; finally, performing extrusion and injection molding to obtain the wood-plastic product with the natural wood grains on the whole body once. The simulated wood grains have the characteristics of verisimilitude, naturality, contingency, no repeatability and durability.

Description

technical field [0001] The invention relates to a wood-plastic home decoration material and a production method thereof, in particular to a production process and a preparation method of a wood-plastic product with natural wood grain throughout. Background technique [0002] Wood products such as floors, wall panels, ceilings, decorative panels, and edge strips are widely used in people's home or office decoration, and the consumption is also very large. They have played an important role in human production and life for thousands of years. . People choose wood as the main decoration material because of its low price and easy-to-obtain economic characteristics, and also because it conforms to people's consumption and life philosophy of being close to nature and pursuing comfort. However, with the explosive growth of population and long-term large-scale deforestation, the existing forest resources on the earth are disappearing at an alarming rate, which has already had a ser...

Problems solved by technology

However, the disadvantage of this method is that it is limited by the customized texture on the roller. The wood texture is monotonous and unnatural, and it will also cause the surface of the wood-plastic panel to be uneven. Another disadvantage of this method is that it is not widely applicable and is only suitable for For wood-plastic products such as boards, there is no way for special-shaped materials with convex and concave surfaces

Another method is hot stamping, which directly prints the wood grain on the surface of the wood-plastic material, or glues the glued paper printed with the wood grain on the surface of the wood-plastic board product. This method also has a single wood texture and lacks the wood texture. , the more important disadvantage is that a lot of solvents are used in the hot stamping and gluing process, which pollutes the environment

At the same time, the residual solvent in the product is slowly released during use, which also brings environmental pollution to living and office places.

Moreover, the imitation wood texture obtained by this method is not permanent, and the glued paper is easy to degumming and cracking or the coating will wear off and disappear.

[0005] The existing methods of imitating wood-plastic products are not only cumbersome and costly, but also the imitation wood texture obtained is only on the surface of wood-plastic products, and it is not realistic and lacks durability.
