Zinc borate corrosion preventing and flame retarding agent

Abstract

The invention relates to a zinc borate corrosion preventing and flame retarding agent which is solvent prepared from effective ingredients and water. The effective ingredients comprise 10-20 wt% of zinc borate, 0-47 wt% of ammonia, 6-60 wt% of 2-aminoethanol and 10-20 wt% of quaternary ammonium surfactants. According to the zinc borate corrosion preventing and flame retarding agent, the problem that a borate flame retarding and corrosion preventing agent is poor in leachability is solved, and the zinc borate which cannot be easily dissolved in water is prepared into a soluble complex which can enable wood to be completely permeated and is finally combined with wood fiber in the mode of the zinc borate; the treated wood is colorless and odorless, the flame retarding and corrosion preventing effects are simultaneously achieved, harm of fungi, moulds, termites, longhorn beetles, lyctus and carpenter bees to the wood can be effectively resisted, the good smoke inhibiting effect and the good leachability resistance are achieved, the leachability of the normally-used borate flame retarding and corrosion preventing agent is larger than or equal to 80 percent, and the leachability of the zinc borate is about 3 percent.

Description

technical field [0001] The invention relates to a flame retardant, in particular to a zinc borate anticorrosion flame retardant. Background technique [0002] In recent years, borides have been widely used in the food antiseptic industry and indoor flame retardant industry due to their good anti-corrosion and anti-mold effects and considerable flame-retardant effects, which are non-toxic and environmentally friendly to humans and animals. With the improvement of people's environmental protection requirements, the application of colorless, odorless and non-toxic boride preservatives in the wood preservation industry is also increasing. Boron compounds currently used in mass production of anti-corrosion and flame-retardant wood mainly include: Borax decahydrate: Na 2 B 4 o 7 10H 2 O, (wherein the percentage of boron is 11.34%); Borax pentahydrate: Na 2 B 4 o 7 ·5H 2 O, (wherein the percentage of boron is 14.84%); boric acid: H 3 BO 3 , (wherein the percentage of boro...

But its biggest shortcoming is that it has not been able to effectively fix it in wood so far, and its resistance to loss is poor.

In order to improve the loss resistance of borides, the measures currently taken mainly include 1. Apply a layer of waterproof paint on the treated wood surface or impregnate it with oil-borne preservatives and use it outdoors or in an environment that is in contact with the ground. The effect of this method is Generally, and the maintenance cost is high; 2. Impregnating borides and polymer monomers (such as adhesives) into wood together, as the monomers polymerize into polymers, encapsulating borides in polymers can also be used Reduce the loss of borides, but this method reduces the flame-retardant and anti-corrosion effect of borides, so the scope of use is not very wide
