Problems solved by technology

This invention has fundamentally changed the situation that traditional sintered ordinary bricks do not have heat preservation, and achieves the purpose of energy saving and environmental protection. However, the hardness of the heat preservation bricks prepared by this invention is not large, and the heat preservation effect is limited, which greatly affects the service life and quality of heat preservation bricks.

Abstract

A high-strength, fireproof and insulating brick is characterized in that the high-strength, fireproof and insulating brick comprises an inner core, a reinforced layer and a fireproof layer, a transition layer, the reinforced layer and the fireproof layer sequentially covers the inner core, the inner core is of a solid rectangular structure of 200 * 120 * 25 mm, the thickness of the reinforced layer is 10-20 mm, and the thickness of the fireproof layer is 8-15 mm. The insulating brick made by adopting a three-layer structural design has good thermal-insulation and fireproof properties and excellent mechanical properties, the heat conductivity coefficient is smaller than 0.35 W / m.K, the compressive strength is greater than 26.7 MPa, the tensile strength is greater than 5.72 MPa, and the water absorption rate is lower than 1%.

Description

technical field [0001] The invention relates to the technical field of thermal insulation bricks, in particular to a high-strength fireproof thermal insulation brick and a preparation method thereof. Background technique [0002] For a long time, clay solid bricks have been used as the most important wall material in the construction industry, which not only destroys a large amount of land every year, but also destroys the ecological environment. Actively develop energy-saving, land-saving, and waste-saving new wall materials to replace traditional solid clay bricks, which will have significant social and economic benefits for changing the mode of economic growth and promoting technological progress in my country's building materials industry and construction industry. At the same time, with the promotion of building energy conservation and the continuous improvement of people's demand for living environment comfort, thermal insulation materials have attracted more and more ...
