Definitions
- the present invention relates to a non-combustible treatment liquid, and more particularly, to a non-combustible treatment liquid, which is mainly composed of a boron compound for use in a material which is mainly flammable, that is, a material mainly composed of cellulose such as wood, paper and natural fiber. And a non-combustible treatment liquid.
- the flame retardant solution includes various compounds such as a phosphorus compound, a nitrogen compound, a boron compound, and a halogen compound.
- the boron compound has relatively little damage and discoloration of the material, which does not generate a harmful gas of a thermal decomposition product during combustion.
- Drugs containing a boron compound as a main component have a remarkable effect of suppressing heat generation by a dehydration carbonization action.
- the dehydration carbonization is a process in which a chemical is heated to generate an acid or a base, and cellulose is dehydrated at a low temperature in a short time to form water and carbon.
- this combustion suppression effect is composed of two functions, namely, an endothermic effect due to evaporation of water, and a reduction in heat generation rate due to generation of a carbon residue having a slow burning rate.

- the fixing property of the chemical is improved, the combustion suppressing effect is enhanced, and the occurrence of leaching can be suppressed as much as possible.
- the leaching inhibitory effect can be exhibited by adding a plant extract containing a polyphenolic compound as a main component to the treatment solution, but the addition of antimony tartrate further improves the leaching inhibitory effect. Become.
- This non-combustible treatment liquid can be widely applied to members containing cellulose as a main component, such as wood, paper, and natural fibers.
- the non-combustible treatment liquid of the present invention is prepared by adding phosphoric acid and a silane coupling agent to a weak acid or weak alkali metal salt aqueous solution containing a boron compound to form a mixed aqueous solution, and the mixed aqueous solution mainly contains a polyphenol compound. It is a mixture of plant extract and antimony tartrate.
- the material to be impregnated or imparted is a member mainly composed of cellulosic materials such as wood, paper and natural fibers.
- the solubility of the boron compound alone is low, so that the boron compound needs to be a high-concentration solution in order to efficiently penetrate the material.
- the solubility is improved by the catalytic action of a weak acid or weak alkali metal salt.
- metal salts of weak acids or weak alkalis include sodium fluoride, sodium phosphite, and sodium sulfite. And sodium borofluoride.
- the content of the metal salt of a weak acid or weak alkali is 110% by weight of the total components.

- Representative examples include aminosilane, ethoxysilane, methoxysilane, and the like.
- KPN-3504, KBM-3063, KBM-3103C etc. are adopted.
- the content of the silane coupling agent is 0.1-5% of the total weight of the components.
- the content is less than 0.1%, it is difficult to impart film-forming properties, and if it exceeds 5%, the viscosity of the liquid increases, and it is difficult to treat the material.
- the use of a polyphenol-based substance as a skin extract component reduces the amount of drug leached.
- the use of the polyphenol-based compound is intended to aim at a chemical change that dissolves the boron compound in water after the material is dried by the adsorption of the boron compound by the polyphenol-based compound.
- a purified tannin is mainly used for the polyphenol conjugate.
- the content of polyphenol compound is 0.5-40% of the total weight of the components. If the content is less than 0.5%, the effect is weak. If it exceeds 40%, the fixing amount of the boron compound may be reduced.
- the second is a method in which a mixed solution of a boron compound and a polyphenolic compound is used, the temperature is maintained at a temperature in a temperature range where no precipitation occurs, and the material is fixed inside the material.
- the latter method is adopted in terms of fixing efficiency.
