Inflaming retarding sponge

Abstract

The invention discloses an inflaming retarding sponge, which comprises the following raw materials of, by weight, 100-120 parts of polyether polyols, 65-70 parts of toluene diisocyanate, 15-23 parts of biphenyl phosphate, 10-30 parts of polyoxosilane, 0.05-0.5 parts of triethylenediamine, 0.1-1.0 parts of stannous caprylate, and 4-5 parts of water. In the invention, the fire retardant biphenyl phosphate is added to the traditional sponge foam material to prepare the inflaming retarding sponge, which does not combust in case of fire, but is melted by heating, thus hidden danger of a fire accident can be reduced, and black smoke generated in carbonization is reduced. The inflaming retarding sponge not only possesses characteristics of traditional sponge such as good elasticity, high pullingforce, etc., but also possesses advantages of simple production technology, flame retardation, safety, environmental protection, etc.

Description

technical field [0001] The invention belongs to macromolecule materials, more specifically a flame-retardant sponge. Background technique [0002] Sponge is a widely used product, including building decoration materials, packaging materials and household items. However, when the traditional sponge is ignited by fire, it will burn automatically. The burning speed is fast, the fire is strong and there is a lot of black smoke. The flame produced by the burning of the sponge cannot be extinguished immediately with water. It is one of the main sources of flame and smoke in a fire in a place. [0003] Chinese patent, application number: 200510014721.9, patent name: high elastic sponge, discloses a formula of high elastic sponge, including the following components and weight percentage: natural rubber 20-35%, synthetic rubber 20-35%, resin 30% -60%, metal oxide 2-10%, fatty acid 2-6%, crosslinking agent 3-5%, accelerator 2-6%, pore forming agent 10-16%, urea derivative 15-20%, an...

[0003] Chinese patent, application number: 200510014721.9, patent name: high elastic sponge, discloses a formula of high elastic sponge, including the following components and weight percentage: natural rubber 20-35%, synthetic rubber 20-35%, resin 30% -60%, metal oxide 2-10%, fatty acid 2-6%, crosslinking agent 3-5%, accelerator 2-6%, pore forming agent 10-16%, urea derivative 15-20%, anti-aging Compared with the prior art, the formula of this invention has the advantages of high elastic sponge without water absorption, high strength and high elongation, but its fire resistance is poor, which cannot meet people's requirements for fire performance.

[0004] Chinese patent, application number: 96121286, patent name: Composite fireproof sponge board, discloses a method for making a composite fireproof sponge board, the board uses the commonly used sponge board as the basic skeleton material, and adds inorganic fireproof fillers in its pores material, forming a composite fireproof sponge board, which has the characteristics of good fire resistance, moisture resistance, heat preservation, sound insulation, easy installation, and long service life. However, the composite fireproof sponge board is cumbersome, and the inorganic fireproof filler is easy to Falling off, not suitable for products such as packaging materials and household items
