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

[0020] A flame-retardant nano-composite material, made of the following raw materials and their proportions by weight: 40% low-density polyethylene; 20% antimony trioxide; 1% antioxidant; 5% carboxylated nitrile rubber; Silicon oxide 25%; the balance is deionized water.

Embodiment 2

[0022] A flame-retardant nano-composite material, made of the following raw materials and their proportions by weight: 45% high-density polyethylene; 18% magnesium hydroxide; 0.8% antioxidant; 3% neoprene; 22% nano-titanium dioxide ; The balance is deionized water.

Embodiment 3

[0024] A flame-retardant nano-composite material, made of the following raw materials and their proportions by weight: 50% low-density polyethylene; 15% aluminum hydroxide; 0.5% antioxidant; 2% chlorosulfonated polyethylene; nano-titanium dioxide 20%; the balance is deionized water.

[0025] The advantages of the present invention are: the composition of each raw material in the flame-retardant nanocomposite material has an effective flame-retardant effect, and the toughening agent added at the same time can reduce the brittleness of the polymer material, improve the impact resistance, and greatly prolong the flame-retardant nanocomposite. The service life of the composite material, the addition of the oxidant can effectively prevent the aging phenomenon of the flame-retardant nanocomposite material, which meets the demand.

Abstract

The invention discloses a fire retardation nanometer composite material, which is prepared from the following raw materials, by weight: 40-50% of a resin, 15-20% of a fire retardation agent, 0.5-1% of an antioxidant, 2-5% of a toughening agent, 20-25% of nanometer oxide powder, and the balance of deionized water. The fire retardation nanometer composite material has the following advantages that: a fire retardation effects is effectively enhanced with the composition of various raw materials in the fire retardation nanometer composite material, polymer material brittleness can be reduced and impact resistance can be increased with the added toughening agent so as to substantially prolong a service life of the fire retardation nanometer composite material, occurrence of aging phenomenon of the fire retardation nanometer composite material can be effectively prevented with antioxidant addition, and requirements can be met.

Description

technical field [0001] The invention relates to a composite material, 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. [0003] Therefore, in order to solve the above problems, a new technical solution is provided to meet the demand. Contents of the invention [0004] The purpose of the present invention is to provide a flame-retardant nanocomposite material. [0005] The technical scheme adopted in the present invention is: [0006] A flame-retardant nanocomposite material, made of the followin...
