Abstract

The invention provides a soft porcelain material with high weather resistance and a preparation method thereof, wherein the soft porcelain material comprises the following raw materials by weight: 5-15 parts of Portland cement, 50-70 parts of quartz sand, 10-30 parts of heavy calcium carbonate, 2-8 parts of a modifier, 0.5-6 parts of a flame retardant, and 2-5 parts of a curing agent. The modifier is waterborne polyurethane modified acrylic emulsion, epoxy resin modified acrylic emulsion or a mixture of the waterborne polyurethane modified acrylic emulsion and the epoxy resin modified acrylic emulsion. The invention provides a preparation method of the soft porcelain, wherein the preparation method comprises the three steps of material preparation, mixing and forming. According to the soft porcelain disclosed by the invention, waterborne polyurethane or epoxy resin is introduced into the acrylic emulsion in a chemical copolymerization manner for modification, and through the interaction of the waterborne polyurethane or epoxy resin and the acrylic emulsion, the generated emulsion comprehensively has excellent performances of acrylic acid and waterborne polyurethane / epoxy resin, and the defect that the acrylic emulsion is sticky in hot and crisp in cold is overcome; and the produced soft porcelain is not easy to break, good in elasticity and excellent in weather resistance.

Description

technical field [0001] The invention relates to the technical field of soft porcelain production, in particular to a soft porcelain material with high weather resistance. Background technique [0002] Soft porcelain is a kind of flexible decorative material. It uses non-metallic industrial tailings, construction waste, stone powder, sand and other materials as the main production materials. Molding technology, shaped under the curve temperature, can vividly express various artistic effects such as bricks, wood, stone, leather, ceramics, braided fabrics and three-dimensional reliefs. The thickness is between 2mm-10mm, and it is flexible and not easy to break. A new type of low-carbon and environmentally friendly green lightweight building decoration material. Because of its light weight, good flexibility, diverse shapes, and good weather resistance, it is widely used in the field of architectural decoration. [0003] At present, soft porcelain on the market often uses acryl...
