Abstract

The invention discloses an energy-saving and environment-friendly heat insulation material and a preparation method thereof, and relates to the technical field of heat insulation materials. The heat insulation material is prepared from the following raw materials in parts by weight: 20-38 parts of acrylic emulsion mortar, 6-12 parts of polyurethane, 16-22 parts of porous aluminum phosphate, 8-12 parts of phosphorus-containing glue, 6-10 parts of hollow glass microbead, 4-8 parts of barium carbonate, 3-7 parts of modified polyimide fiber, 5-10 parts of epoxy-terminated polydimethylsiloxane, 3-5parts of nano zinc borate and 1-2 parts of a complex antioxidant. The heat insulation material has very outstanding heat insulation effect, and very high anti-press and anti-bending strength and flame retardant property.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to an energy-saving and environment-friendly thermal insulation material and a preparation method thereof. Background technique [0002] Common thermal insulation materials, among them, inorganic materials mainly use porous materials such as open-cell expanded perlite, aerated concrete, rock wool, glass wool and other substances, and organic materials mainly use polymer foaming to improve the thermal insulation performance of materials. However, insulation materials are light, loose, porous, etc. These conventional insulation materials have poor insulation performance and poor compressive and flexural strength. In addition, some fires often occur in the environment. Conventional insulation materials not only It cannot play the role of containing the fire, but also promotes the fire to burn, causing greater harm. Therefore, thermal insulation materia...
