Background

The traditional building exterior wall tiles are high in specific gravity, hard and brittle, and can fall off due to aging of an adhesive layer after a long time to injure pedestrians, so that the traditional building exterior wall tiles are gradually forbidden to be used for high-rise buildings by national policies; later, latex paints for exterior wall coatings were recommended, but latex paints suffer from poor aesthetics, poor durability, and high rework costs. The soft ceramic tile made by mixing 10-30% of organic high polymer into inorganic filler overcomes the defects of the two external wall materials. However, the traditional soft ceramic tile has the defects of more inorganic components, lower waterproofness and durability, easy aging and cracking and the like.

Patent CN109704723A discloses a wear-resistant and aging-resistant soft ceramic tile, which is prepared from the following raw materials in parts by weight: 165-175 parts of soil, 43-45 parts of modified attapulgite, 17-19 parts of gas phase white carbon black, 6-8 parts of polypropylene fiber, 1-3 parts of polyethylene wax, 1.6-1.8 parts of nano zinc oxide and 1.1-1.3 parts of nano anion powder. The wear-resisting ageing-resistant soft ceramic tile that this patent provided, intensity is high, and the wearability is strong, produces the mar in avoiding the use, can stand to blow to the sun simultaneously, delays ageing, increases soft ceramic tile's practicality. The defect of the patent is that the process is complex and the cost is high.

Patent CN108275961A discloses a method for making soft ceramic tiles, which is made from the following raw materials in parts by weight: 12-16 parts of calcium silicate, 20-25 parts of clay, 10-13 parts of stone powder, 15-20 parts of white sand, 3-6 parts of inorganic toner, 9-12 parts of porcelain slag, 2-5 parts of a waterproof agent, 1-3 parts of polypropylene short fiber, 0.5-1.5 parts of an antioxidant and 30-40 parts of water. The patent adds the soil and the porcelain slag to fully exert the advantage of waste recycling, reduces the pollution of the soil and the porcelain slag to the environment and embodies the process of changing waste into treasure; meanwhile, polypropylene short fibers and a waterproof agent are added, so that the flexibility of the soft porcelain is improved, and the soft porcelain has a waterproof function and is high in product functionality. The defects of the patent are that the inorganic components are high, the water permeability is high, and the foam is easy to be emptied and foamed after a long time.

In view of the above, there is a need to develop a new soft tile with certain water resistance and aging resistance.
