Problems solved by technology

At present, there are very few woods used after anti-corrosion and flame-retardant treatment in my country, and most of them use traditional wood treatment agents that are harmful to humans and the environment. Therefore, it is very necessary to develop and develop a highly efficient and new wood anti-corrosion and flame retardant of

Abstract

The invention discloses a wood preservative flame retardant and a preparation method thereof. The wood preservative flame retardant comprises the following components by mass: 15%-20% of amidinourea phosphate, 5%-8% of zinc borate, 10%-15% of diammonium hydrogen phosphate, 1%-4% of ammonium molybdate, 6%-8% of chlorothalonil, 3%-6% of disodium octoborate tetrahydrate, 2%-4% of dioctyl dimethyl ammonium chloride, 1%-3% of tetradecyl dimethyl benzyl ammonium chloride, 0.5%-2% of fatty alcohol polyoxyethylene ether, 5%-10% of nano silicon dioxide, and 20%-50% of water. The beneficial effect is that the treated wood has excellent flame retardant smoke suppression properties, broad-spectrum fungicidal and insecticidal effect, excellent antiseptic and mouldproof effect and other advantages, and is good in permeability, strong in erosion resistance, low in cost, and simple in preparation process.

Description

technical field [0001] The invention relates to the technical field of wood modification treatment, in particular to a wood antiseptic flame retardant and a preparation method thereof. Background technique [0002] Wood is a natural organic material with obvious biological characteristics, easy to be attacked by bacteria, insects, marine borers and other organisms, and easy to burn and absorb moisture, which will greatly affect its application effect and application field. With the improvement of people's living standards, the demand for wood is also increasing. Making full use of existing timber resources and taking the road of sustainable development is the only way for the development of my country's timber industry. Treating wood with anti-corrosion and flame-retardant treatment is one of the important ways to increase the service life of wood, prevent fires, save wood and protect forest resources. At present, there are very few woods used after anti-corrosion and flam...
