A kind of production technology of gypsum self-leveling material

Abstract

The invention discloses a production process of a gypsum self-leveling material. The specific production process steps are as follows: S1, preparation of paste powder: pulverizing the phosphogypsum, sieving, and dedusting to obtain initially refined phosphogypsum; S2, preparation of preliminary paste: Dilute the gypsum slurry, inject pure water, and use a stirring device to stir evenly to obtain the gypsum slurry in a diluted state; S3, preparation of modified plaster slurry: take the preliminary diluted gypsum slurry, graphene oxide, concentrated sulfuric acid, calcium salt solution, and Mix water ethanol and oleic acid, and use a stirring device to stir evenly, then repeatedly freeze and thaw, and finally perform drying treatment; S4, finished product preparation: sequentially take modified paste, water gypsum, cement, quartz sand and gypsum retarder Mix and stir evenly with a stirring device to obtain a gypsum self-leveling material; S5, discharging; S6, packaging.

Description

technical field [0001] The invention belongs to the field of processing gypsum self-leveling materials, in particular to a production process of gypsum self-leveling materials. Background technique [0002] Self-leveling mortar has excellent workability, can save labor, improve construction efficiency, and is widely used in architectural decoration projects. Self-leveling mortar includes inorganic self-leveling mortar and organic self-leveling mortar, and inorganic self-leveling mortar also includes cement-based self-leveling mortar and gypsum-based self-leveling mortar. Gypsum has the characteristics of short setting time, good molding effect, and beautiful appearance. It is a commonly used building material for decoration. The surface layer gypsum-based self-leveling floor mortar has the advantages of high construction efficiency, environmental protection, energy saving, and small shrinkage rate. It has developed rapidly in my country in recent years. [0003] Under the ...

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a production process of gypsum self-leveling material, so as to solve the problem that in the process of solid-liquid mixing and stirring, it is difficult, the components are difficult to control, the timing is even more difficult to grasp, and at the same time, the efficiency cannot be taken into account. The problem is that the timing of adding solid ingredients and liquid ingredients to the mixing drum can be precisely controlled, so that the solid ingredients can be added before the liquid ingredients, and can be refilled repeatedly in a small amount to avoid caking caused by one-time filling. Problems, make the operation process more reasonable, so as to achieve better mixing effect, higher mixing efficiency, and higher degree of automation
