Expandable polystyrene thermal insulation material

Abstract

The invention discloses an expandable polystyrene thermal insulation material comprising the following raw materials in percentage by weight: 40-50% of expandable polystyrene, 0.1-1% of p-aminomethylbenzoic acid, 0.1-3% of p-toluenesulfonic acid, 0.1-3% of dipropylene glycol butyl ether, 0.1-3% of waterborne acrylic emulsion and 40-60% of alkyd resin. The expandable polystyrene thermal insulationmaterial has the characteristics of high strength, flame retardance, high temperature resistance and good waterproofness.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to an expandable polystyrene thermal insulation material. Background technique [0002] At present, with the increasing shortage of energy and resources and the warming of the global climate, more and more people begin to pay attention to the development and application of building insulation materials. Reducing the indoor heat dissipation of buildings to the outside plays an important role in creating a suitable indoor thermal environment and saving energy. Building thermal insulation materials can effectively reduce the indoor heat of the building to the outside. [0003] At present, there are many kinds of thermal insulation materials with different characteristics, which are mainly divided into inorganic thermal insulation materials and organic thermal insulation materials. Inorganic thermal insulation materials include foam concrete, perlite, rock wool, g...

AI Technical Summary

Problems solved by technology

Inorganic thermal insulation materials include foam concrete, perlite, rock wool, glass wool and other thermal insulation materials based on traditional cement, which have the advantages of high strength, good safety performance, non-flammability, and durability; organic materials include polyurethane , styrene, polyethylene and other foaming materials. Although organic materials have the advantages of light weight, low thermal conductivity and good thermal insulation performance, they have disadvantages such as flammability, easy aging and poor durability.

Although in the prior art, there is a modification of organic materials, which is compounded with organic materials by adding inorganic materials, thereby improving its comprehensive performance, but it has the disadvantages of low bonding strength and poor flame retardant effect of composite materials.
