Problems solved by technology

The existing concrete hollow blocks or hollow bricks have poor thermal insulation effect, so after the wall is built, a certain thickness of thermal insulation mortar or external insulation board should be applied on the outer wall or inner wall. Not only the construction is cumbersome, the construction period is long, and the wall The surface is easy to hollow and crack, seriously affecting the insulation effect, and the service life of the insulation layer is short; especially the externally attached polystyrene board has poor fire resistance and flame retardancy. Once exposed to an open flame, it will burn and release a large amount of toxic gas, which will bring great security risks

Embodiment 1

[0009] The raw materials used in the non-load-bearing thermal insulation bricks involved in the present invention are composed of 35% ceramsite, 25% vitrified microbeads, 10% pumice, 12% cement, 3% fly ash, 5% lime, and FTC phase. Variable energy storage insulation material 3%, gypsum 3%, asbestos 3% and admixture 1%. The admixture is composed of 3 parts of concrete early-strength agent, 4 parts of concrete air-entraining agent, 1 part of concrete water reducing agent and 2 parts of cement water repellent in parts by weight. The particle size of the crushed pumice stone is 5-10mm, the length of asbestos is 5-10mm.

Abstract

The invention discloses a non-bearing insulating brick with high compressive strength, high fireproof grade, good thermal insulation effect, and good flame retardant performance, comprising the following ingredients: 35-45 %(v / v) of ceramic pellets, 20-25 %(v / v) of vitrified micro bubbles, 10-15 %(v / v) of pumice stone or slag, 8-12 %(v / v) of cement, 3-5 %(v / v) of fly ash, 3-5 %(v / v) of lime, 2-3 %(v / v) of FTC phase change energy storage thermal insulation material, 2-3 %(v / v) of gypsum, 1-3 %(v / v) of asbestos or rock wool, and 1-2 %(v / v) of additive, wherein, the additive comprises 3-4 weight portions of early strength agent, 3-4 weight portions of air entraining agent, 1-2 weight portions of water reducing agent, and 1-2 weight portions of water repellent. The non-bearing insulating brick can be prepared into solid brick, perforated brick and other types and specifications, is convenient for construction and can reduce the bearing capacity of foundation soil, so that the non-bearing insulating brick is suitable for constructional building envelope, especially for high-rise buildings.

Description

technical field [0001] The invention relates to building bricks, in particular to a non-load-bearing thermal insulation brick. Background technique [0002] At present, most buildings adopt frame structure, especially high-rise buildings, and the body of wall generally uses concrete hollow blocks or hollow bricks to form. The existing concrete hollow blocks or hollow bricks have poor thermal insulation effect, so after the wall is built, a certain thickness of thermal insulation mortar or external insulation board should be applied on the outer wall or inner wall. Not only the construction is cumbersome, the construction period is long, and the wall The surface is easy to hollow and crack, seriously affecting the insulation effect, and the service life of the insulation layer is short; especially the externally attached polystyrene board has poor fire resistance and flame retardancy. Once exposed to an open flame, it will burn and release a large amount of toxic gas, which w...
