Abstract

The invention discloses a heat preservation brick which comprises a hollow brick serving as a brick body shell and a cement foam material accommodated in the cavity of the brick body, wherein the hollow brick comprises the following raw materials: cement, construction waste earth, ceramsite, lime and perlite; the cement foam material comprises the following raw materials: cement, calcium carbonate, calcium sulfate, sialite, calcium borate, corn stalk powder, AR glass fiber, carboxymethyl cellulose, a water reducing agent, a foaming agent, a foaming regulator, a catalyst, a crosslinking agent, a foam stabilizer, glyoxal and water. The heat preservation brick has the advantages of being excellent in heat preservation and insulation, sound insulation effect, compression resistance and the like, and is light in weight; a method for preparing the heat preservation brick does not need autoclaved curing, is low in equipment investment, simple in process, simple and convenient to operate, convenient to popularize, and stable in product quality.

Description

【Technical field】 [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a thermal insulation brick. 【Background technique】 [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. Existing thermal insulation composite bricks or blocks mainly include multiple forms such as inlaying thermal insulation materials, setting thermal insulation interlayers, thermal insulation holes, and trenches. As one of the thermal insulation materials for houses, non-fired foamed bricks at room temperature are more and more popular because of their thermal insulation, sound insulation, fire prevention, and strength superior to traditional thermal insulation materials. However, the foamed bricks in the existing market have disadvantages such as poor impact resistance a...
