Abstract

The invention discloses a radiation-resistant non-woven fabric material which comprises following raw material in parts by weight: 130 to 150 parts of polypropylene, 4 to 6 parts of polyvinyl alcohol,2 to 3 parts of melamine, 0.1 to 0.2 parts of N-methylimidazole, 0.3 to 1 part of vanadyl-acetylacetonate, 2 to 3 parts of allyl thiourea, 1 to 2 parts of dodecenyl succinic acid, 3 to 4 parts of potassium titanate whiskers, 3 to 5 parts of trichloroisocyanuric acid, 0.1 to 0.2 parts of nonylphenol, 2 to 3 parts of bee wax, 0.8 to 1 part of sorbitan monooleate, 17 to 20 parts of toughening additives and 1 to 2 parts of oleamide. The potassium titanate whisker added in the invention has very good anti-radiation effect. Vanadium acetylacetonate, stannous sulfide, and the like have a very good effect of improving heat stability. The non-woven material of the present invention has good stability and superior comprehensive performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a radiation-resistant non-woven fabric material and a preparation method thereof. Background technique [0002] Non-woven fabric is composed of oriented or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Features such as reuse. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing. It is a new generation of environmentally friendly materials with good strength, breathability, waterproof, and environmental protection. , flexible, non-toxic and tasteless, and cheap. It is a new generation of environmentally friendly materials, with the ch...
