Transparent wood processing technology for manufacturing high-light-transmittance wooden crafts

Abstract

The invention discloses a transparent wood processing technology for manufacturing high-light-transmittance wood crafts, and relates to the technical field of wood processing. The processing technology comprises the following steps: after lignin is removed from wood, the wood is placed in steeping liquor containing silver nanowires for steeping treatment, and then is steeped with transparent resin to obtain transparent wood. According to the method, before the delignified wood is filled with a polymer matrix, the silver nanowires with the length-diameter ratio are filled in the channels of the wood, the film channels constructed by the silver nanowire films are formed in the channels of the wood, and due to the fact that the silver nanowire films have good flexibility, the film channels formed in the wood channels have good stress dispersion functions, so that the polymer matrix is added to the wood channels, such that the film channels formed in the wood channels have the good stress dispersion effect so as to dissipate the stress generated during the curing expansion of the polymer matrix by the film channels so as to achieve the technical effects of no damage to the internal weak structure of the wood and no collapse of wood cells.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a transparent wood processing technology for making wooden handicrafts with high light transmittance. Background technique [0002] Wooden handicrafts occupy a large share in the handicraft market, which can be roughly divided into three categories: small, medium and large. It combines culture and art and has a long history. It has been widely used in many fields such as gifts, home decoration, and outdoor decorative lights. It is deeply loved by people for making exquisite wooden gifts and home decorations. [0003] Transparent wood is a kind of biomass material with transparent optical properties obtained by modifying natural wood. It is a new type of material that integrates the advantages of high modulus, high strength, high toughness, low density, biodegradability, and environmental protection. It has a unique structural level and composition, and when ...

Problems solved by technology

For example, Chinese patent CN2019103851501 discloses a method for preparing transparent wood using an organic solvent, as well as the prepared transparent wood and its application. In this technical solution, the veneer sample is first dried at 105±5°C, and then placed in an aqueous ethanol solution at 85 The dried veneer samples were extracted at -95°C, rinsed with ethanol aqueous solution, then retained bleaching with hydrogen peroxide aqueous solution, and finally filled with a polymer matrix to obtain a light-transmitting wood base Materials; although the above-mentioned technical scheme can obtain light-transmitting wood-based materials, the filled polymer matrix will expand when it enters the cell wall and solidifies, destroying the internal weak structure of the wood, causing the cells of the wood to collapse, thereby exposing the wood fibers and exposing The wood fiber has a large specific surface area and can absorb a large amount of water, which causes the volume of the wood to expand easily in a humid environment, resulting in a decrease in the strength of the wood
