Problems solved by technology

However, most of the wood treatment in the prior art is to separate flame retardant and anticorrosion into a single treatment. Although this can achieve better flame retardant and anticorrosion effects, the treatment process is relatively complicated, and the time is long, the efficiency is low, and the energy consumption is large. , which is not

Abstract

The invention discloses a compound wood fire-retardant preservative and preparation method thereof. The compound wood fire-retardant preservative comprises the following components by mass: 10%-15% of N-hydroxy ethyl ethylamine triacetic acid, 5%-10% of sodium octoborate, 5%-10% of zinc borate, 5%-10% of amidinourea phosphate, 1%-4% of ammonium molybdate, 5%-15% of nanosilicon dioxide, 2%-5% of nano titanium dioxide, 4%-8% of copper dimethyl dithiocarbamate, 1%-3% of sodium dodecyl sulfate and 20%-60% of water. The beneficial effects are that the compound wood fire-retardant preservative has good permeability, erosion resistance, and good fire-retardant, smoke suppression, corrosion protection, sterilization and other effects, and has good enhancement, wear-resisting, long-term non-discolouring and other functions on wood treatment.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a composite wood flame retardant preservative and a preparation method thereof. Background technique [0002] Wood and its products are widely used in interior decoration, furniture manufacturing, house construction and exterior decoration, but they have problems such as shrinkage and swelling, poor dimensional stability, easy corrosion, and easy combustion, which will greatly limit its application. effects and fields of application. Therefore, before the wood is used, it is usually necessary to carry out flame-retardant, anti-corrosion and other modification treatments to better improve the performance of the wood. However, most of the wood treatment in the prior art is to separate flame retardant and anticorrosion into a single treatment. Although this can achieve better flame retardant and anticorrosion effects, the treatment process is relatively complicated, a...
