Embodiment 1

[0089]Example 1: Manufacture of long-acting flame retardant composition for wooden cultural relics and ancient buildings of the present invention and evaluation of flame retardant effect

[0090] 65 parts by weight of water and 25 parts by weight of ammonium nitrilo(methylene)triphosphonate (AMGUARD DR) represented by Chemical Formula 1 were added to a flask equipped with a stirrer, and stirred and mixed for 2 hours. Add 5 parts by weight of 3-aminopropyl triethoxysilane (3-aminopropyl triethoxysilane) to the mixed solution produced, and after stirring for 1 hour and 45 minutes, add diethylene glycol monobutyl ether and butyl cellosolve as penetrating agent 5 parts by weight of the 4:6 (weight ratio) mixture was stirred for 2 hours and 30 minutes to manufacture the fire-retardant composition for wooden cultural relics and ancient buildings.

[0091] The long-acting flame retardant composition for wooden cultural relics and ancient buildings produced was evaluated for whether i...

Abstract

The invention discloses a long-acting flame retardant composition for wooden cultural relics and ancient buildings and a flame retardant treatment method thereof. The flame retardant composition includes a flame retardant, a penetrating agent, a precursor of a hydroxyl silicone oil compound and a solvent; the flame retardant For the organic phosphate shown as chemical formula 1, the penetrating agent includes the glycol ether compound shown in chemical formula 2, the hydroxyl silicone oil compound precursor is shown as chemical formula 3, and the solvent includes water; the flame retardant treatment method: Apply or disperse the long-lasting flame-retardant composition for wooden cultural relics and ancient buildings on the wooden surface, or impregnate wood into the flame-retardant composition; penetrate the long-lasting flame-retardant composition for wooden cultural relics and ancient buildings Inside the porous structure; drying of the impregnated flame retardant composition. The invention has excellent permeability to porous structures such as wood, and has good flame-retardant effect. It will not cause pollution such as whitening, falling off, and stains on the flame-retardant treated wood, and can maintain long-term effectiveness. burning treatment.

Description

technical field [0001] The invention belongs to the technical field of wood flame retardant, and in particular relates to a long-acting flame retardant composition for wooden cultural relics and ancient buildings and a flame retardant treatment method thereof. Background technique [0002] For some combustible objects used in daily life, we need flame retardancy treatment. For example, curtains, partitions, doors and other building interior and exterior materials, automobiles, trains, ships, airplanes and other means of transportation, flammable accessories of various electrical appliances, toys, clothing, furniture, wooden cultural relics and ancient buildings etc., flame retardant treatment is necessary to prevent the spread of fire or in accordance with legal regulations. Now, plywood, fiberboard, carpets, curtains, etc. used in special places such as high-rise buildings, theaters, hotels, hospitals, etc. are generally stipulated as statutory flame-retardant treatment ob...
