Abstract

The invention discloses a Chinese fir anticorrosion modification agent and a preparing method and constructing process thereof, and belongs to the technical field of wood anticorrosion treatment. Theanticorrosion modification agent is prepared by adding copper-ion-loaded and borate-ion-loaded graphene oxide, waterborne polyurethane, a dispersing agent and a defoaming agent to water for mechanicalstirring and ultrasonic processing. The constructing process includes the steps of conducting impregnation treatment on Chinese fir through the prepared anticorrosion modification agent and conducting thermal treatment on the Chinese fir through a superheated steam drying box. By means of the prepared anticorrosion modification agent and the constructing process, the anticorrosion property and anticorrosion stability of the Chinese fir can be remarkably improved, the hardness, wear resistance and size stability of the Chinese fir can be greatly improved, and the Chinese fir anticorrosion modification agent has the remarkable economic value and social benefits.

Description

technical field [0001] The invention belongs to the technical field of wood anticorrosion treatment, and in particular relates to a fir anticorrosion modification treatment agent, a preparation method and a construction process thereof. Background technique [0002] Chinese fir is one of the tree species with the largest planting area in my country, and is an important fast-growing timber species unique to my country. Chinese fir wood is widely used in the fields of construction, furniture, and wood-based panels. However, due to the fast growth rate and short rotation period of Chinese fir, the wood contains a high proportion of young and middle-aged wood, the wood is loose, and the strength is poor, so Chinese fir products are easy to produce. There are problems with rot and moth. Plantation fir must be treated with antiseptic before use. [0003] Water-based preservative injection is a more commonly used method of wood preservation in recent years. Chromated copper arse...
