Problems solved by technology

[0003] In the prior art, the insulation bricks are mainly polystyrene boards, but this kind of insulation bricks wastes a lot of resources and energy, and the cost is high. Second, the air permeability is poor, which not only causes a lot of waste of resources, but also seriously pollutes the environment. The insulation bricks have low compressive strength. Poor fire resistance and other properties, in addition to short service life, which limits the technical development of insulation bricks

Abstract

The invention discloses high-performance heat-insulation bricks for a building. The high-performance heat-insulation bricks are prepared from the following raw materials in parts by weight: 34 to 40 parts of modified fly ash, 28 to 30 parts of high molecular microspheres, 22 to 26 parts of portland cement, 16 to 20 parts of bentonite, 14 to 18 parts of kaolin, 20 to 24 parts of woody fibers, 16 to18 parts of glass microspheres, 8 to 10 parts of fireproof clay, 4 to 6 parts of de-foaming agent and 4 to 8 parts of filler. The high-performance heat-insulation bricks for the building have the advantages that the heat-insulation bricks have excellent compressive strength and good fireproof performance; furthermore, the heat-insulation bricks have a long service life and relatively high practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of thermal insulation bricks, in particular to a high-performance thermal insulation brick for construction and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the demand for building bricks has doubled, especially the large number of demolition and construction projects in the city has increased the demand for building bricks. It is a new type of building material that can replace ceramic tiles. It is mainly suitable for bathrooms, kitchens, TV background walls, bedrooms, and exterior walls. Brick raw material, its chemical composition is mainly SiO2, followed by Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, SO2, etc. The total content of SiO2, Al2O3 and Fe2O3 in coal gangue is more than 80%, which is a natural Clay raw materials can replace clay ingredients to fire bricks; the main chemical components of fly ash are SiO2, Al2O3, Fe2O3, etc., accounting for 90% o...
