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 inflaming retarding composition for a wooden cultural relic heritage building and inflaming retarding treatment method thereof. The inflaming retarding composition includes a fire retardant, a penetrating agent, a hydroxyl silicone oil compound precursor and a solvent. The fire retardant is an organic phosphate having a chemical formula 1, the penetrating agent includes a glycol ether compound having a chemical formula 2, the hydroxyl silicone oil compound precursor has a chemical formula 3 and the solvent contains water. The method includes spreading or dispersing the long-acting inflaming retarding composition for the wooden cultural relic heritage building on the wooden surface or soaking wood in the inflaming retarding composition; enabling penetration of the long-acting inflaming retarding composition for wooden cultural relic heritage building into the wooden porous structure; drying the penetrated inflaming retarding composition. Accordingto the invention, the penetration performance for the wooden porous structure is excellent, the inflaming retarding effect is good and pollution including whitening, falling, staining and the like isnot caused to wood subjected to inflaming retarding treatment and long term effectiveness can be achieved. The composition and the method are especially suitable for inflaming retarding treatment forthe wooden cultural relic heritage building.

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...
