Abstract

The invention discloses a high-weather-resistant fir plate preparation method, and belongs to the technical field of wood anti-aging treatment. The preparation method comprises: carrying out a reaction on 2,4-dihydroxybenzophenone and nanometer titanium dioxide to prepare 2,4-dihydroxybenzophenone grafted nanometer titanium dioxide, carrying out first modification treatment on a fir plate by usinga mixed dispersion liquid of the 2,4-dihydroxybenzophenone grafted nanometer titanium dioxide and antioxidant, and carrying out second modification treatment on the fir plate by using a polyurethaneaqueous solution. According to the invention, the prepared fir plate has advantages of excellent weather resistance, good wear resistance, good dimensional stability and remarkable economic value andsocial benefit.

Description

technical field [0001] The invention belongs to the technical field of anti-aging treatment of wood, and in particular relates to a preparation method of fir board with high weather resistance. Background technique [0002] Chinese fir is the main fast-growing timber in southern my country. It has the advantages of fast growth, straight stem shape, easy processing, and special aroma. In addition, fir is rich in resources and moderate in price, so it is widely used in furniture and interior decoration and other fields, such as flooring, luxury wooden door frames, core strips of blockboards, etc. However, during long-term use, fir boards are prone to discoloration due to the action of thermal oxygen and ultraviolet light, resulting in poor appearance. In order to improve the aging resistance of Chinese fir, Deng Shaoping (Deng Shaoping, Lin Qiaojia, Lin Zi, Ma Changcheng; Effects of accelerated aging on the properties of Chinese fir in plantation forests treated with high tem...
