Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the drawings and specific embodiments: figure 1 As shown, the preparation method of the novel layered nano-PAL flame-retardant material of the present invention is as follows: a. The PAL mineral raw material 1 is beneficiated, crushed and purified 2 to make a 90-98% high-purity PAL material 3; b , The high-purity PAL material 3 is subjected to depolymerization, dispersion, and ultra-micro processing 4 to produce a nano- and sub-micron PAL material 5 smaller than 100-800 nm; c. After the nano- and sub-micron PAL material 5 is inorganically activated 6 Make a large specific surface area nano, sub-micron PAL material 7; d. After organic modification 8 the large specific surface area nano, sub-micron PAL material 7 is made into an organic nano, sub-micron PAL material 9; e, finally The organic nano-, sub-micron PAL material 9 is combined with a polymer matrix 10 to form a polymer layered nano-PAL fla...

Abstract

The invention relates to a preparation method for a novel layered nano PAL flame-retardant material. The preparation method comprises the following steps: a. conducting mineral dressing, crushing and purifying treatment to PAL mineral raw materials to prepare high-purity PAL materials with purity of 90-98 percent; b. conducting depolymerization and ultrafine crushing treatment to the high-purity PAL materials to prepare nano and submicron PAL materials with size less than 100-800nm; c. conducting inorganic activation to the nano and submicron PAL materials to prepared nano and submicron PAL materials with large specific surface area; d. conducting organic modification to the nano and submicron PAL materials with large specific surface area to prepare organic nano and submicron PAL materials; and e. the organic nano and submicron PAL materials being composited with polymeric matrixes to prepare polymeric layered nano PAL flame-retardant composite materials, or the organic nano and submicron PAL materials being composited with other fire-fighting materials to prepare layered nano PAL flame-retardant composite materials. The layered nano PAL flame-retardant materials prepared through the method have the advantages of flame retarding, low smoke, no toxicity, good environmental performance and the like.

Description

Technical field [0001] The invention relates to a novel layered nano-PAL flame retardant new material prepared from natural ecological inorganic non-metallic materials. It has the properties of "flame retardant, low smoke, non-toxic and environmental protection", and is used to replace environmental protection in the field of flame retardancy. The traditional varieties with lack of functions realize the dual functions of flame retardant and environmental protection, and belong to the field of new material science and advanced inorganic non-metallic materials. Background technique [0002] In recent years, fires have occurred frequently in our country, and many of them are extremely serious fire accidents, causing heavy casualties and economic losses. Practice has proved that flame-retardant materials play a major role in reducing fire casualties, avoiding major economic losses and protecting the ecological environment. Therefore, the present invention is highly pertinent to the ...
