Low-odor artificial board and preparation method thereof

Abstract

The invention provides a low-odor artificial board and a preparation method thereof, the low-odor artificial board comprises an odor adsorbent, the odor adsorbent comprises a layered material and an adsorption material, the layered material is preferably MXene, and the adsorption material is preferably cyclodextrin. According to the low-odor artificial board, the odor grade of the artificial board can be reduced, the mechanical property of the artificial board is not affected, and the manufacturing method is simple.

Description

technical field [0001] The invention belongs to the field of wood-based panels, and in particular relates to a low-odor wood-based panel and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's awareness of environmental protection, formaldehyde-free wood-based panels have developed rapidly, and major customized home furnishing companies have launched formaldehyde-free home furnishing products. The formaldehyde-free wood-based panels have been deeply rooted in the hearts of the people. However, according to feedback from custom home furnishing companies, the complaint rate of odor problems of formaldehyde-free wood-based panels is higher than that of aldehyde-containing panels. The main reason is that the wood raw materials used in formaldehyde-free wood-based panels will release some odorous substances, especially after being processed into shavings or fibers. Most consumers do not know the source of the odor. Once th...

[0004] CN 110696140 A discloses a production method of low-odor veneer wood-based panels, specifically reports that adding tea leaves, orange peel powder and slow-release flavor-absorbing capsules to woody materials reduces board odor, but the introduction of non-woody materials will cause The mechanical properties of the board are reduced; CN 106945145 A discloses a production process for low-odor environmentally friendly wood-based panels, which promotes odor discharge by optimizing the shape of shavings, changing the structure of wood-based panels, using high-quality raw materials to reduce odor sources, and effectively reducing the board Odor level, but Changing the shape of the shavings and the structure of the board will lead to a large change in the production process; CN105313202 A discloses a method for removing the odor of mahogany, which uses saturated steam to treat the wood to remove the odor of the wood; CN1364682 A discloses the deodorization treatment of euonymus wood The method comprises the steps of soaking wood with sodium hydroxide solution, ammonia solution and ethanol solution at room temperature for deodorization, so that the lower fatty acids in the wood react with the above-mentioned substances to form tasteless salts or esters with apple flavor; CN 103624852 A discloses a The method of deodorizing Mizuki rosewood wood is to use low-temperature plasma treatment to increase the escape rate of wood odor molecules, and use ozone to oxidize and decompose odor substances. However, the above-mentioned methods will cause wood degradation to varying degrees, resulting in significant mechanical properties of wood. decline
