Multifunctional wood inflaming retarding agent and method for preparing smoke suppressing and inflaming retarding pinus sylvestris solid wood by utilizing of multifunctional wood inflaming retarding agent

Abstract

The invention discloses a multifunctional wood inflaming retarding agent and a method for preparing smoke suppressing and inflaming retarding pinus sylvestris solid wood by utilizing of the multifunctional wood inflaming retarding agent, and relates to the multifunctional wood inflaming retarding agent capable of antiflaming, suppressing smoke and preventing running off and a technique for processing the pinus sylvestris solid wood by utilizing the antiflaming and smoke suppressing properties of the multifunctional wood inflaming retarding agent. To solve the problems that the pinus sylvestris solid wood is rich in grease and can not be immersed easily, the flame retardation property of an existing wood inflaming retarding agent is single, and antiflaming components are easy to run off, the wood inflaming retarding agent comprises, by weight, 22-56 parts of phosphoric acid amidinourea, 15-25 parts of boric acid, 24-56 parts of water-solubility ammonium polyphosphate, 1-5 parts of ammonium molybdate and 20-45 parts of silica sol. The preparation method of the inflaming retarding and smoke suppressing pinus sylvestris solid wood comprises the following steps. Firstly, the microwave process is carried out on the dried pinus sylvestris solid wood. Secondly, the pinus sylvestris solid wood is placed in inflaming retarding liquid to be pressurized and immersed in a vacuum mode. The dried inflaming retarding and smoke suppressing pinus sylvestris solid wood has a good smoke suppressing property, the smoke suppressing effect and anti-running-off property are obvious.

Description

technical field [0001] The invention relates to a multifunctional flame-retardant, smoke-suppressing, and loss-resistant wood flame retardant and a flame-retardant and smoke-suppressing process for treating pine sylvestris solid wood. Background technique [0002] In the 21st century when all kinds of resources are increasingly tight, with the increase of population and the improvement of people's living standards, renewable green environmental protection materials have attracted more and more attention. Wood, as a natural degradable and renewable environmental protection material, plays an important role in people's life and architectural decoration. However, the flammability of wood materials greatly limits its use in many environments. In recent years, due to the frequent occurrence of fires caused by wood materials, the loss of life and property caused is even more immeasurable. People also have higher requirements for wood, a flammable material - flame retardancy and s...
