Problems solved by technology

[0002] Wood is widely used in the fields of construction, transportation, furniture, and interior decoration, but its flammability can easily bring fire hazards, causing casualties and property losses. The use of suitable flame retardants will further expand the use of wood and protect people. It is of great significance to ensure the safety of property and ensure the stable growth of the national economy
Existing flame retardants generally only increase the ignition point of the surface layer impregnated with flame retardants, but cannot prevent the burning of wood under the action of continuous high temperature, and will produce a large amount of high-temperature smoke after burning

Embodiment Construction

[0010] The technical solutions of the present invention will be further described below in combination with specific preferred embodiments.

[0011] A high-efficiency, environmentally friendly and smoke-suppressing wood flame retardant, its components are proportioned by mass percentage: 20% phosphoric acid, 12% dicyandiamide, 40% ammonium dihydrogen phosphate, 10% zinc borate, 10% antimony oxide, molybdenum Ammonium Acid 5%, Sodium Alkane Sulfonate 2%, Pentaerythritol 1%. Wherein, the mass concentration of the phosphoric acid is 80%-90%.

[0012] The preparation method is as follows: (1) Weigh each component according to the mass percentage ratio; (2) Add dicyandiamide and water to prepare an aqueous solution with a mass concentration of 20% to 40%, and mix it under 70°C to 90°C under stirring conditions. Slowly add phosphoric acid under low temperature, react at constant temperature for 0.5-2 hours to obtain amidinourea phosphate GUP, then add ammonium dihydrogen phosphate,...

Abstract

The invention discloses a high-efficiency eco-friendly smoke-inhibition timber fire retardant and a preparation method thereof. The high-efficiency eco-friendly smoke-inhibition timber fire retardant comprises, by mass, 15-25% of phosphoric acid, 12-20% of dicyandiamide, 25-40% of ammonium dihydrogen phosphate, 5-15% of zinc borate, 5-15% of antimony oxide, 3-6% of ammonium molybdate, 0.5-3% of sodium alkyl sulfonate and 0.1-1% of pentaerythritol. Compared with the existing fire retardant, the high-efficiency eco-friendly smoke-inhibition timber fire retardant contains a large amount of nitrogen, phosphor and boron fire retardant components, has the advantages of good flame retardation, no halogen, environment-friendliness, no irritation and no corrosivity. The guanylurea phosphate obtained by in-situ reaction has good flame retardation and smoke inhibition effects. The used zinc borate is conducive to further flame retardation and smoke inhibition. The preparation method has simple processes. The high-efficiency eco-friendly smoke-inhibition timber fire retardant has good timber flame retardation processing effects and has a low cost.

Description

technical field [0001] The invention relates to the technical field of wood flame retardants, in particular to a high-efficiency, environment-friendly and smoke-suppressing wood flame retardant and a preparation method thereof. Background technique [0002] Wood is widely used in the fields of construction, transportation, furniture, and interior decoration, but its flammability can easily bring fire hazards, causing casualties and property losses. The use of suitable flame retardants will further expand the use of wood and protect people. It is of great significance to ensure the safety of property and ensure the stable growth of the national economy. Existing flame retardants generally only increase the ignition point of the surface layer infiltrated with flame retardants, but cannot prevent the burning of wood under the action of continuous high temperature, and will produce a large amount of high-temperature smoke after burning. It has been proved that most of the casua...
