Exterior wall board insulation material with excellent mechanical properties

Abstract

The invention discloses an exterior wall board insulation material with excellent mechanical properties. The exterior wall board insulation material comprises the following raw materials in parts by weight: 30-60 parts of expanded polystyrene, 25-35 parts of polyurethane-modified epoxy resin, 35-45 parts of organosilicon-modified phenolic resin, 8-12 parts of modified graphite powder, 1.5-2.5 parts of bis-tributylphenol polyoxyethylene ether, 3-4 parts of epoxidized soybean oil, 4-8 parts of mica powder, 8-12 parts of graphene nanosheet, 6-10 parts of calcium silicate, 2-4 parts of aluminum oxide, 3-5 parts of sodium silicate, 2-3 parts of magnesium oxide, 4-12 parts of calcined clay, 1.5-2.5 parts of phosphoric acid, 1.5-2.5 parts of p-methylsulfonic acid, 2-3 parts of a physical foaming agent and 35-55 parts of water. The exterior wall board insulation material with the excellent mechanical properties, provided by the invention, is uniformly foamed, has excellent heat insulation and the excellent mechanical properties, and has very good fire resistance.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an external wall panel thermal insulation material with excellent mechanical properties. Background technique [0002] In recent years, external wall insulation materials have been developed rapidly. Wall panels are involved in more and more fields, such as construction, electronic appliances, wood processing and other industrial sectors. External wall insulation materials have become an indispensable and important material in modern industrial society. External wall panels can make building walls The body is neat and beautiful, so as to beautify the urban environment and protect the walls of buildings. However, the external wall panels currently on the market have problems such as insufficient thermal insulation performance and fire resistance, and poor mechanical properties, which affect the appearance of buildings and reduce service life of building walls...
