Lumber combustion inhibitor and method for producing the same

Abstract

The invention discloses a wood fire retardant, which consists of the following raw materials by weight portion: 5 to 10 portions of borax, 15 to 25 portions of ammonium polyphosphate, 0.5 to 1 portion of ammonium molybdate, 30 to 40 portions of ammonium sulfate, 30 to 40 portions of diammonium phosphate, 15 to 25 portions of reinforcing agent, and 860 to 1,270 portions of water (adding or no adding), wherein the reinforcing agent consists of 30 to 45 portions of phthalic anhydride, 65 to 70 portions of triethanolamine, and 130 to 140 portions of water. A method for producing the fire retardant comprises the steps of: 1, the preparation of the reinforcing agent; 2, the preparation of the fire retardant; and 3, the preparation of a fire-retardant impregnation liquid during the concrete impregnation application, wherein the last step can be prepared as required. The fire retardant releases less harmful gas and smoke smog in combustion environment, has small pollution to the atmosphere and simple production technology, and is favorable for improving the bonding strength after the reinforcing agent is added in the fire retardant.

Description

Wood flame retardant and production method thereof technical field The invention relates to a wood flame retardant composed of organic matter and inorganic matter. Background technique CN1294172 discloses Mr. Qiao Wanjun's "high-efficiency flame retardant" patent application technology. The flame retardant decomposes NH3, N2, H2, CO2, CO and other gases at high temperature, which has a barrier effect on combustibles and thus flame retardant, but these gases It is harmful to human body and pollutes the atmosphere. CN101306545 discloses Kunming University of Science and Technology's patent application technology of "a wood combustible agent and its preparation method". A surfactant is added to the flame retardant to reduce the surface tension of the flame retardant solution to increase the penetration depth of the drug , to increase the drug loading rate to expand the flame retardant effect, but the synthesis of ureidophosphate, the synthesis of melamine phosphate, the comp...

CN101306545 discloses Kunming University of Science and Technology's patent application technology of "a wood combustible agent and its preparation method". A surfactant is added to the flame retardant to reduce the surface tension of the flame retardant solution to increase the penetration depth of the drug , to increase the drug loading rate to expand the flame retardant effect, but the synthesis of ureidophosphate, the synthesis of melamine phosphate, the compounding of flame retardants and other processes are required, and there are also cooling, filtering, crystallization, drying, and crushing. and other processes, the process is more complicated

Many wood flame retardants contain ammonium. Ammonium will form NH3 gas in the presence of water and high temperature, which will appear in the form of air bubbles in wood and affect the bonding strength of wood. How to improve the effect of ammonium-containing flame retardants on the bonding strength Negative impact of the problem, so far no data reports and real products on the market
