Abstract

The invention discloses a fluorogypsum-based interior wall plastering material and its production process. The weight ratio of raw materials is: 8000-10000 parts of modified fluorogypsum, 0-15000 parts of aggregate, 20-100 parts of water-retaining thickener, 50-250 parts of redispersible latex powder. The present invention uses waste fluorine gypsum as raw material, and firstly modifies the fluorine gypsum raw material, that is, through low-temperature calcination treatment, and carries out grinding treatment together with activator, coagulation regulator and expansion inhibitor, and then obtains a hydration rate Modified fluorogypsum with the advantages of fast and short setting time; the modified fluorogypsum, aggregate, water-retaining thickener and redispersible latex powder are used as raw materials and stirred evenly according to the above weight ratio, and the fluorogypsum-based interior wall plastering material is obtained The embodiment of the present invention provides a utilization method of industrial waste fluorogypsum. The fluorogypsum-based interior wall plastering material prepared by using modified fluorogypsum has high strength and stable volume compared with existing plastering materials. , not easy to crack, low-temperature quick-setting and no efflorescence.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fluorine gypsum-based interior wall plastering material and a production process thereof. Background technique [0002] Fluorogypsum is a by-product of sulfuric acid hydrolysis of fluorite to prepare hydrofluoric acid. The main component is type II anhydrous calcium sulfate, which is strongly acidic, pH=2~4, and the annual discharge exceeds 2 million tons. At present, most of the fluorogypsum in China is stored as solid waste, which not only occupies land resources, but also pollutes the environment. Due to the increasing consumption of natural resources, the use of waste fluorine gypsum to produce high value-added interior wall plastering materials can not only make full use of waste resources, but also protect the soil and groundwater environment. Materials are an important part of construction projects, so they are of great significance. [0003] At present, the...
