Abstract

The invention discloses a flame-retardant and aging-resistant composite heat-preservation material, as well as a preparation method and application thereof. The composite heat-preservation material comprises the following components: polystyrene particles and a mixture consisting of magnesium oxide, magnesium sulfide and a superfine efficient building material additive. The invention further discloses the method for preparing the composite heat-preservation material and the application of the composite heat-preservation material in the heat-preservation of a building. The flame retardance of the composite heat-preservation material can reach an A1-level standard, and the composite heat-preservation material has high heat-preservation performance and aging resistance. In addition, a heat-preservation plate made from the composite heat-preservation material has higher compressive strength, anti-permeability and chemical corrosion resistance, and has the characteristics of lightweight, good fireproof effect, high strength, good convenience in construction, short construction cycle, good heat-preservation effect and the like.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a flame-retardant and aging-resistant composite thermal insulation material and a preparation method thereof. The invention further relates to the application of the composite thermal insulation material in building thermal insulation, which belongs to the field of building thermal insulation materials. Background technique [0002] The full name of polystyrene particles is expanded polystyrene foam particles, also known as expanded polystyrene particles. The material is made by expansion and foaming of expandable polystyrene resin beads as the basic raw material. It is the main aggregate of polystyrene particle insulation mortar. Polystyrene particles have the advantages of good thermal insulation effect and low price, and are suitable for the interior and exterior insulation of the exterior walls of industrial and civil buildings, as well as the partition walls and basements of...
