Abstract

The invention discloses a gypsum-based ceramic tile adhesive and a preparation method thereof. The adhesive comprises a gypsum component, a sand component, a retarder component, an anti-sag component,a waterproof agent component, a water reducing agent component, a water retaining agent component and a reinforcing thickening agent component. The absolute dry tensile bonding strength of the adhesive can reach 1.0 MPa and can reach more than 0.56 MPa after 24 hours of immersion. The gypsum-based ceramic tile adhesive meeting the standard of common cement-based ceramic tile adhesives is preparedfrom low-strength gypsum powder as a binding material, an aggregate and an additive, so that the defects of the cement-based ceramic tile adhesives are effectively overcome; the industrial byproductgypsum is wider in application, and the gypsum-based ceramic tile adhesive follows the thought of national resource recycling economy, and expands the advantages of gypsum.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a gypsum-based ceramic tile adhesive and a preparation method thereof. Background technique [0002] With the development of industrial technology, the development of domestic chemical companies is booming, and the benefits they bring are immeasurable, but the impact on the environment cannot be underestimated. Desulfurization gypsum produced by desulfurization in power plants, phosphogypsum produced by phosphoric acid in phosphating plants, etc. are all industrial waste residues. Long-term landfills will occupy a large amount of land and pollute the environment. At present, the accumulation of industrial by-product gypsum in China has reached hundreds of millions. tons, so the treatment of gypsum needs to be solved urgently. [0003] The main component of gypsum is calcium sulfate dihydrate, a resource that can be recycled. After dehydration at a certain temperatu...
