Novel high-heat-preservation flame-retardant thermal insulation material

Abstract

The invention discloses a novel high-heat-preservation flame-retardant thermal insulation material having a flame-retardant polyethylene bubble layer as intermediate basic layer. On the upper surface of the flame-retardant polyethylene bubble layer is attached a nonwoven fabric or woven fabric layer, on the upper surface of the nonwoven fabric or woven fabric layer is attached a first aluminum film layer, on the lower surface of the flame-retardant polyethylene bubble layer is attached a second aluminum film layer, on the lower surface of the second aluminum film layer is attached an EPE (expandable polyethylene) foam material layer, and on the lower surface of the EPE foam material layer is attached a third aluminum film layer. The inventive thermal insulation material has the characteristics of high strength, good elasticity, good resistance to oxidation, corrosion and thermal insulation effects, and high flame retardancy.

Description

technical field [0001] The invention relates to a building material, in particular to a novel high heat-retaining, flame-retardant and heat-insulating material for building, and belongs to the technical field of building materials. Background technique [0002] With the development of the economy, the global demand for energy is increasing day by day. In the ever-increasing total energy consumption, building energy consumption accounts for about 11% to 25% of the total energy consumption. Therefore, the issue of building energy conservation has attracted more and more attention The attention of many countries. Practice has proved that the most direct and effective way to save energy in buildings is to use thermal insulation materials. At present, the commonly used insulation materials mainly include: foam glass, polystyrene foam, nanoporous insulation material, rubber powder polystyrene particle insulation material, insulation mortar, aerated concrete, foamed asbestos, comp...

AI Technical Summary

Problems solved by technology

But it generally has the following disadvantages: First, poor shock absorption performance, easy to oxidize and corrode, short service life, and generally lose waterproof and heat preservation functions gradually in two to three years

Secondly, this material has low tensile strength and longitudinal and transverse tensile strength, and is easy to break when it comes into contact with foreign objects or under heavy pressure, and its surface flatness is poor, and the reflectivity of sunlight is low; heat insulation and heat preservation performance are relatively poor

Thirdly, there is no air barrier layer in the middle of this material, and the internal and external energy is easy to form convection and conduction, thereby affecting the heat insulation performance; finally, it is easy to burn and has poor flame retardancy.
