Abstract

The invention provides a sulphoaluminate cement composition, and a preparation method and an application thereof. The sulphoaluminate cement composition comprises a sulphoaluminate cement base material, quartz sand, staple fiber, sawdust, nano-scale silicon dioxide, a water retention agent, a cement fast-drying agent, and a high-molecular cement water-reducing agent. According to the invention, a part of the quartz sand is fetched; various additives are added to the quartz sand, and the mixture is well mixed by stirring; the sulphoaluminate cement base material is added, and stirring is continued, wherein remaining quartz sand is added during the stirring process; and the cement composition can be obtained when the mixture is well mixed. With the ratio of the raw materials and with the interactions among the raw materials, the cement composition provided by the invention can be hardened fast. The cement composition can be applied in manufacturing home crafts or bathroom sets. An obtained finished product has the advantages of no internal injury, high structural strength, smooth surface, and uniform frost. The product has high strength and can stand box drop from a height of 60cm. The preparation process is highly efficient and has low cost. A qualification rate reaches 99%.

Description

technical field [0001] The invention relates to the technical field of sulphoaluminate cement compositions, in particular to sulphoaluminate cement compositions and applications thereof. Background technique [0002] At present, a large part of household handicraft decorations and bathroom suites use unsaturated polyester resin, which is molded with silicone molds. During the production process, harmful substances such as benzene, toluene, xylene, and styrene are released due to incomplete reactions, causing environmental pollution. Therefore, household handicraft decorations made of cement materials have appeared on the market, and are loved by consumers, especially foreign consumers such as the United States and Europe. But general cement process is difficult to realize, mainly exists the following three problems: the first, cement forming usually uses hard mold. Second, cement strength is generally measured with a thickness of 7 cm, and aggregates of 1 to 2 cm are used,...
