Embodiment 1

[0018] Example 1 58.3% of quartz sand with a maximum particle size of 1.0mm, 5.0% of 52.5 grade sulphoaluminate cement, 5.0% of 52.5 grade white cement, 10.0% of mineral powder, 15.0% of pure acrylate copolymer emulsion (solid content is 50.0%), 0.5% polydimethylsiloxane defoamer 5300, 0.5% polysiloxane powder water repellent SHP-50, 0.5% N-phenyl-α-aniline antioxidant, 0.2% glass fiber and 5.0% water are mixed and stirred evenly to obtain a slurry with a certain fluidity, and the slurry is sprayed on a mold with a certain pattern to a thickness of 3.0-5.0mm, and then pressed into the alkali-resistant glass Fiber mesh cloth, after standing for 0.5 hours, enter the drying tunnel at a temperature of 100.0±10.0°C to dry completely, and then remove the formwork to cut into facing bricks of the required size. After testing, the flame retardant performance of the facing brick reaches A2 level, the elastic modulus is 4520.0MPa, and the water absorption rate is 3.2%.

Embodiment 2

[0019] Example 2 50.0% of stone powder with a maximum particle size of 2.0mm, 8.0% of 52.5 grade Portland cement, 3.0% of building gypsum powder, 5.0% of silica fume, 10.0% of mineral powder, and 10.0% of styrene- Acrylate copolymer emulsion (50.0% solid content), 4.7% vinyl acetate-ethylene copolymer emulsion (550% solid content), 0.5% N-phenyl-α-aniline antioxidant, 1.0% polysilicon Mix and stir the oxane powder water repellant SHP-50, 0.8% glass fiber, and 7.0% water, and press the prepared slurry onto the mold with a thickness of 3.0-5.0mm, and enter it after standing for 0.5 hours After the temperature is 80.0±10.0 ℃, it is completely dried in the oven, and then it can be cut into required size decorative bricks after demoulding. After testing, the flame retardant performance of the facing brick reaches A2 level, the elastic modulus is 3547.0MPa, and the water absorption rate is 3.5%.

Embodiment 3

[0020] Example 3 25.0% of quartz sand with a maximum particle size of 1.0mm, 20.0% of water slag with a maximum particle size of 1.0mm, 5.0% of 52.5 grade sulfoaluminate cement, 5.0% of 52.5 grade white cement, and 12.0% of mineral powder , 8.0% pure acrylate copolymer emulsion (solid content 50.0%), 15.0% vinyl acetate-vinyl chloride-acrylic acid copolymer emulsion (solid content 46.0%), 5.0% silicone-acrylate copolymer emulsion (solid content 45.0%), 0.3% silicone ethylene glycol defoamer, 0.5% 4.4-bis (2.2-dimethylbenzyl) diphenylamine antioxidant, 0.5% calcium stearate water repellent, 0.5% The hydroxypropyl methylcellulose thickener, 0.2% mineral fiber, and 3% water are mixed and stirred, and the prepared slurry is sprayed on the mold with a thickness of 3.0 to 4.0 mm, and after standing for 1 hour, it enters the temperature After being completely dried in the oven at 60.0±10.0°C, it can be cut into flame-retardant decorative bricks of the required size after demoulding. ...

Abstract

The invention relates to a flame-retardant flexible facing tile and a preparation method thereof. The flame-retardant flexible facing tile is characterized by comprising the following raw materials in percentage by mass in terms of the total quantity of the raw materials: 40.0-46.0% of aggregates, 10.0-40.0% of inorganic cementing material, 10.0-30.0% of flexible modifier, 1.0-5.5% of functional additive, 0-1.0% of fiber, and 0-10.0% of water. The flame-retardant flexible facing tile is obtained by carrying out mixing stirring, molding and drying on the raw materials. According to the flame-retardant flexible facing tile prepared according to the invention, with the inorganic cementing material as a bonding material and high-molecular polymer as the flexible modifier, the flame-retardant flexible facing tile not only has the advantages of high toughness, good air permeability, strong hydrophobicity, good matching degree with various substrates, rich patterns and colors and the like, but also has very good flame retardancy and good durability capable of keeping the integral structure for a long time.

Description

technical field [0001] The invention relates to a flame-retardant flexible decorative brick which can be used for internal and external walls, table tops, etc. and has excellent flame-retardant performance and super long service life and a preparation method thereof, which belongs to a building decoration material. Background technique [0002] Flexible facing brick is a recently developed decorative material with certain flexibility that can be used for indoor and outdoor walls and countertops. It is not only convenient for construction, but also has good decorative effects. Compared with rigid decorative materials in terms of safety, it is also especially suitable for high-rise exterior walls. However, the current flexible decorative tiles mainly use polymer emulsion as the cementing material and flexibility modifier. Such materials or products have good elasticity and flexibility, but there are also two main problems: [0003] One is that facing bricks are mainly used as...
