Novel flame retardant, heat insulation and heat preservation material structure

Abstract

A novel flame retardant, heat insulation and heat preservation material structure is characterized by comprising a first aluminum foil layer, a weaved cloth layer, cystic bubbles, a second aluminum foil layer, melamine foam and an aerogel felt; the cystic bubbles are filled with flame retardant inert gas; nanometer flame retardant particles are added in the bubble layer, the height of the bubbles ranges from 2 to 16 mm, and the width of the bubbles ranges from 3 to 30 mm; the thickness of the melamine foam ranges from 2 to 10 mm, and the gas hole ratio of the foam ranges from 90% to 97%; the thickness of the aerogel felt ranges from 8-15 mm; the first aluminum foil layer, the weaved cloth layer, the cystic bubbles and the second aluminum foil layer are bonded through polyurethanes binding agents, and the thickness ranges from 30 to 50 mm; the second foil layer and the melamine foam are bonded through PA-80 binding agents, and the thickness ranges from 30 to 55 mm; the melamine foam and the aerogel felt are bonded through crylic acid binding agents, and the thickness ranges from 35 to 65 mm. The heat preservation material can be applied horizontally or made into pipes for use, the flame retardant property is good, the damping effect is good, the weight is low, and the heat preservation and energy conservation effects are ideal.

Description

technical field [0001] The invention relates to a thermal insulation material structure, in particular to a flame-retardant and heat-insulating thermal insulation material structure. Background technique [0002] In the general environment of the global low-carbon economy, the development of environmental protection and energy-saving materials is one of the key links. At present, the heat insulation materials commonly used in the market are mostly polyurethane foam, EPE foam or non-woven fabric and aluminum foil composite materials, etc. These materials have poor shock absorption performance and weak corrosion and aging resistance, which reduces their service life. After about two years of use, its thermal insulation and waterproof function disappears; again, these materials are poor in flame retardancy and have potential safety hazards. At present, the heating pipeline generally has the problems of large heat loss and low thermal efficiency. Traditional insulation methods...
