Abstract

The invention discloses an expanded perlite composite thermal insulation material and a preparation method thereof, and belongs to the technical field of building materials. The thermal insulation material is prepared from the following raw materials in parts by weight: 12-18 parts of brucite fiber, 12-18 parts of serpentine fiber, 26-28 parts of expanded perlite, 2-4 parts of polystyrene particles, 60-80 parts of acrylic resin emulsion, 8-12 parts of tourmaline and 5-10 parts of a dispersant. The thermal insulation material has the advantages of simple process, widely source raw materials, low cost, outstanding thermal insulation effect of products and excellent impact resistance, and is a novel efficient composite thermal insulation material.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an expanded perlite composite thermal insulation material and a preparation method thereof. Background technique [0002] Thermal insulation material refers to the material that can block the transfer of heat flow, also known as thermal insulation material. Traditional thermal insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., new thermal insulation materials, such as airgel felt, vacuum panels, etc. They are used in building envelopes or thermal equipment, materials or material composites that resist heat flow transfer, including thermal insulation materials and cold insulation materials. On the one hand, thermal insulation materials meet the thermal environment of building space or thermal equipment, and on the other hand, they also save energy. [0003] There are many kinds of thermal insulation materials, which can generally be classi...
