Problems solved by technology

In addition, due to the high probability of building fires and serious hazards, the fire spreads rapidly when a fire occurs, and there are problems such as difficult escape and rescue; therefore, the fire resistance and flame retardancy of wall tiles are very important for fire prevention and rescue.
The existing wall tiles have been improved in terms of aesthetics, sound insulation or fire prevention, but there are still few wall tiles with high comprehensive performance such as heat preservation, fire prevention, compression resistance, and moisture resistance.

Abstract

The invention provides a flame-retardant wall brick. The flame-retardant wall brick is prepared from the following raw materials in parts by weight: 100-200 parts of white cement, 50-100 parts of expanded polystyrene, 15-30 parts of porous flame-retardant hollow microspheres, 50-100 parts of silicon oxide aerogel, 10-20 parts of bentonite or modified bentonite, 5-12 parts of feldspar, 1-3 parts of a water-retaining agent, 5-10 parts of fibers and 2-5 parts of calcium carbonate. The flame-retardant wall brick has good fireproof, moisture-proof, heat-insulating and sound-insulating properties and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flame-retardant wall brick. Background technique [0002] Wall brick is a building material used for walls, which is closely related to the indoor working and living environment. Good quality wall tiles can provide thermal insulation, sound insulation, anti-pollution, anti-radiation space. In addition, due to the high probability of building fires and serious hazards, the fire spreads rapidly when a fire occurs, and there are problems such as difficult escape and rescue; therefore, the fire resistance and flame retardancy of wall tiles are very important for fire prevention and rescue. Existing wall tiles have been improved in terms of aesthetics, sound insulation or fire prevention, but there are still few wall tiles with high comprehensive properties such as thermal insulation, fire prevention, compression resistance, and moisture resistance.
