Composite thermal insulation board and preparation method thereof

Abstract

The invention discloses a composite thermal insulation board and a preparation method thereof, and relates to the technical field of manufacturing of thermal insulation boards. The composite thermal insulation board is prepared from the following components in parts by weight: 15 to 17 parts of expanded perlite, 25 to 30 parts of phenolic resin, 25 to 35 parts of pearlite sand, 20 to 30 parts of inorganic fiber, 1 to 2 parts of penetrant, 3 to 5 parts of water repellent, 3 to 5 parts of modifier, 3 to 5 parts of sodium silicate, 2 to 6 parts of sodium bentonite, 1 to 2 parts of titanium dioxide, 10 to 15 parts of gypsum, 2 to 3 parts of flame retardant, 2 to 3 parts of stabilizer, 3 to 4 parts of trifluoroethyl acrylate, 1 to 2 parts of hydrogenated nitrile rubber, sulfate 0.2 to 0.4 partof ceric sulfate, 15 to 25 parts of absolute ethanol, and 130 to 150 parts of water. The raw materials used in the board of the invention have the characteristics of no toxicity and environmental protection, and the prepared composite thermal insulation board has the characteristics of stable performance, high compressive strength and long service life.

Description

technical field [0001] The invention relates to the technical field of thermal insulation board manufacturing, and more specifically relates to a composite thermal insulation board and a preparation method thereof. Background technique [0002] At present, there are several types of insulation boards for external walls in my country, such as polystyrene foam boards, gypsum boards, cement boards, and expanded perlite boards. It meets the performance requirements of the building envelope, so now the composite material insulation board is paid more attention and has been developed rapidly. The composite material insulation board is a new type of external wall insulation board with multi-directional excellent performance, but the technical development is relatively not. It is too mature, the production process is complicated and diverse, and the properties such as compressive strength and flexural strength are not up to the requirements for use. [0003] Therefore, how to solve t...
