Thermal insulation building material and preparation method thereof

Abstract

The invention discloses a thermal insulation building material and preparation method thereof, and relates to the technical field of building materials. The building material is prepared from, by weight, 15-20 parts of epoxy resin, 14-18 parts of phenolic resin, 16-21 parts of polyurethane, 6-12 parts of vermiculite, 8-15 parts of perlite, 7-15 parts of volcanic ash, 9-14 parts of asbestos, 15-18parts of calcium silicate, 3-7 parts of calcium fluosilicate, 4-8 parts of nanometer aluminium oxide, 5-9 parts of nanosilicon dioxide, 4-8 parts of liquid water glass, 4-7 parts of ceramic fiber, 3-6parts of zinc oxide, 2-4 parts of carbon black, 3-5 parts of fire retardant, 2.5-4.5 parts of antioxygen, 1.2-2.1 parts of defoaming agent, 3-5 parts of photo-thermal stabilizer and 2-4 parts of curing agent; the thermal insulation building material is small in heat conductivity coefficient, large in heat storage coefficient, better in the thermal insulation performance, large in antiflaming coefficient, high in safety performance, good in cracking resistance, shock resistance and ageing resistance, long in service life, simple in the preparation method, low in raw material price, and betterin market application prospects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation building material and a preparation method thereof. Background technique [0002] Building insulation materials are used to reduce the heat emitted from the interior of the building to the outside by taking measures on the building's outer enclosure, thereby maintaining the indoor temperature of the building. Building insulation materials play an important role in creating a suitable indoor thermal environment and saving energy in building insulation. [0003] In the prior art, extruded polystyrene boards, molded polystyrene boards, polyurethane foam boards and other materials are mostly used for building exterior walls to ensure energy-saving and heat preservation of the walls. Under the combined action of alternating and rainwater, air, etc., it is extremely prone to aging and has a low service life, and the flame retardancy of this material is n...

Problems solved by technology

[0003] In the prior art, extruded polystyrene boards, molded polystyrene boards, polyurethane foam boards and other materials are mostly used for building exterior walls to ensure energy-saving and heat preservation of the walls. Under the combined action of alternating and rainwater, air, etc., it is extremely prone to aging and has a low service life, and the flame retardancy of this material is not high enough. Therefore, it is necessary to find a thermal insulation with good thermal insulation performance, low price, and good flame retardancy. Material
