Problems solved by technology

[0002] Existing high-temperature insulation materials generally use glass wool, rock wool, ceramic fiber, etc., but there is a problem: due to the high thermal conductivity of glass wool, rock wool, ceramic fiber and other materials, they cannot meet the higher requirements of flame retardancy. At the same time, the toughness of the existing materials is poor, and it is prone to aging after long-term use, which greatly shortens the service life

Embodiment 1

[0012] A flame-retardant nanocomposite material, made of the following raw materials in parts by weight: 40 parts of the resin, 15 parts of a flame retardant, 1 part of an antioxidant, 1 part of a toughening agent, 10 parts of ceramic fibers, barium sulfate 20 parts, 5 parts of nano-titanium dioxide, 5 parts of nano-silica, 5 parts of glass fiber and an appropriate amount of deionized water, the resin is low-density polyethylene or high-density polyethylene, and the flame retardant is an organosilicon flame retardant.

Embodiment 2

[0014] A flame-retardant nanocomposite material, made of the following raw materials in parts by weight: 50 parts of the resin, 20 parts of a flame retardant, 3 parts of an antioxidant, 3 parts of a toughening agent, 20 parts of ceramic fibers, barium sulfate 30 parts, 16 parts of nano-titanium dioxide, 8 parts of nano-silica, 8 parts of glass fiber and an appropriate amount of deionized water, the resin is low-density polyethylene or high-density polyethylene, and the flame retardant is an organosilicon flame retardant .

Embodiment 3

[0016] A flame-retardant nanocomposite material, made of the following raw materials in parts by weight: 45 parts of the resin, 17 parts of a flame retardant, 2 parts of an antioxidant, 2 parts of a toughening agent, 15 parts of ceramic fibers, barium sulfate 25 parts, 6 parts of nano-titanium dioxide, 6 parts of nano-silica, 6 parts of glass fiber and an appropriate amount of deionized water, the resin is low-density polyethylene or high-density polyethylene, and the flame retardant is an organosilicon flame retardant . The present invention realizes the flame retardant effect by rationally configuring the existing flame retardant and its auxiliary materials, generating a pyrolysis charcoal layer through the organosilicon flame retardant and improving the oxidation resistance of the charcoal layer. After adding organosilicon flame retardants to polymer materials, most of the organosilicon flame retardants will migrate to the surface of the material, forming a polymer gradient...

Abstract

The invention provides a flame-retardant nanocomposite made of the following raw materials in parts by weight: 40 to 50 parts of resin, 15 to 20 parts of a flame retardant, 1 to 3 parts of an antioxidant, 1 to 3 parts of a toughening agent, 10 to 20 parts of ceramic fiber, 20 to 30 parts of barium sulfate, 5 to 8 parts of nanometer titanium dioxide, 5 to 8 parts of nano silica, 5 to 8 parts of glass fiber and an appropriate amount of deionized water. According to the invention, the flame retardant effect is realized by reasonably allocating the existing flame retardant and auxiliary materials thereof, producing a cracked carbon layer by an organosilicone flame retardant and improving the oxidation resistance of the carbon layer.

Description

technical field [0001] The invention relates to the technical field of flame-retardant composite materials, in particular to a flame-retardant nano-composite material. Background technique [0002] Existing high-temperature insulation materials generally use glass wool, rock wool, ceramic fiber, etc., but there is a problem: due to the high thermal conductivity of glass wool, rock wool, ceramic fiber and other materials, they cannot meet the higher requirements of flame retardancy. At the same time, the toughness of the existing materials is poor, and it is prone to aging after long-term use, which greatly shortens the service life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a flame-retardant nano-composite material. By rationally configuring the existing flame retardant and its auxiliary materials, the organic silicon flame retardant is used to generate a cracked carbon layer and improve the resistance of...
