Abstract

The invention discloses a composite thermal insulation board for exterior walls of construction projects and a preparation method thereof, and relates to the technical field of building material preparation. The composite thermal insulation board is prepared from the following components in parts by weight: 12-18 parts of expanded perlite , 20-35 parts of phenolic resin, 25-30 parts of pearl sand, 15-30 parts of inorganic fiber, 1-2 parts of penetrating agent, 3-5 parts of water repellent, 3-5 parts of modifier, 3-3 parts of sodium silicate 5 parts, 2-6 parts of sodium bentonite, 1-2 parts of titanium dioxide, 10-15 parts of fly ash, 10-15 parts of gypsum, 2-3 parts of flame retardant, 2-3 parts of stabilizer, nano-polymer four 4-5 parts of vinyl fluoride, 3-4 parts of trifluoroethyl acrylate, 1-2 parts of hydrogenated nitrile rubber, 0.2-0.4 parts of cerium sulfate, 15-25 parts of absolute ethanol, 120-160 parts of water, the present invention The raw materials used are non-toxic and environmentally friendly, and have good thermal insulation properties. The composite thermal insulation board made has the advantages of stable performance and long service life.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a composite thermal insulation board for exterior walls of construction projects and a preparation method thereof. Background technique [0002] In the building envelope, the wall accounts for the largest proportion of heating energy consumption, accounting for about 32.1% to 36.2% of the total energy consumption. Therefore, how to improve the thermal insulation performance of the wall becomes the top priority. The main function of the external wall insulation board is to keep the internal temperature of the building at an optimal state, and minimize energy loss, that is, heat dissipation. The external wall insulation board "wraps" and protects the exterior of the building, which not only satisfies the insulation performance of the building, but also greatly prolongs the life of the building. [0003] At present, there are several types of insulation boards...
