Preparation method of modified facing tiles for building materials

Abstract

The invention discloses a preparation method of modified facing tiles for building materials. The method comprises the specific preparation steps: (1) mixing stearic acid and deionized water accordingto the mass ratio of 1: 4, putting the mixture into a beaker, heating up the beaker to the temperature of 61 DEG C to 65 DEG C, carrying out stirring for 20 to 30 minutes so as to obtain a stirred solution, mixing magnesium hydroxide and aluminum hydroxide according to the mass ratio of 1: 2, carrying out grinding and crushing for 10 to 11 minutes so as to obtain mixed powder, continuing to mix the mixed powder and the stirred solution according to the mass ratio of 3: 1, carrying out stirring for 38 to 45 minutes at the revolution rate of 185rpm to 205rpm, and carrying out drying and discharging, thereby obtaining modified mixed powder. The preparation method of the modified facing tiles for the building materials, disclosed by the invention, has the advantages of good aging resistance,high bond strength, difficulty in fall-off and high in closed pore rate, the facing tiles can be light in bulk weight and high in heat resistance and have very good heat-insulating property, the flameretardance is good, the flame retardant rating reaches 0 level, irritant gases are not easily generated, and thus, the facing tiles have a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and in particular relates to a preparation method of modified decorative bricks for building materials. Background technique [0002] The current decorative bricks mainly use polymer emulsion as the cementing material and flexibility modifier. Such materials or products have good elasticity and flexibility, but there are two main problems: one is that the decorative bricks are mainly used as walls, etc. However, under the action of light, heat, water and the atmosphere, the organic gel components will gradually age and decompose in a short period of time, thus gradually losing their function, leading to the disintegration of the structure, making the facing brick Chalking or peeling off. The second is that the organic components of this flexible facing brick account for a large proportion. These components have a low ignition point and are easy to burn, and can release a la...

Problems solved by technology

[0002] The current decorative bricks mainly use polymer emulsion as the cementing material and flexibility modifier. Such materials or products have good elasticity and flexibility, but there are two main problems: one is that the decorative bricks are mainly used as walls, etc. However, under the action of light, heat, water and the atmosphere, the organic gel components will gradually age and decompose in a short period of time, thus gradually losing their function, leading to the disintegration of the structure, making the facing brick chalking or shedding

The second is that the organic components of this kind of flexible facing brick account for a large proportion. These components have a low ignition point and are easy to burn. They can release a large amount of irritating and toxic gases when burning, which increases the danger of fire.
