Waterproof gypsum environmental-friendly building block

Abstract

The invention relates to the technical field of building partition materials, in particular to a waterproof gypsum environmental-friendly building block. The waterproof gypsum environmental-friendly building block is produced through the steps of stirring beta semi-hydrated gypsum, a water reducing agent, an inorganic material and a composite water-proofing agent, adding water and performing casting, wherein the percentage by weight of the raw materials is that the weight of the inorganic material is 9-15% of that of the beta semi-hydrated gypsum, the weight of the water reducing agent is 0.4-0.7% of that of the beta semi-hydrated gypsum, the weight of the composite water-proofing agent is 0.7-1.2% of that of the beta semi-hydrated gypsum, and the weight of the water is 58-70% of that of the beta semi-hydrated gypsum. Compared with the prior art, the environmental-friendly building block disclosed by the invention is produced through the following steps of mixing and stirring the beta semi-hydrated gypsum, the inorganic material, the water reducing agent and the composite water-proofing agent, then adding the water, and performing casting and shaping so that the problems that the coagulation time is too long, productivity is difficult to form, the intensity is low, the cost is high, and efflorescence and mildewing occur, are solved.

Description

[technical field] [0001] The invention relates to the technical field of building partition wall materials, in particular to a waterproof gypsum environmental protection building block. [Background technique] [0002] With the rise of new partition wall materials, gypsum products have been widely used in the construction industry because of their fast setting speed, easy molding, low cost, and environmental protection. However, because gypsum is an air-hardening gelling material, its strength when exposed to water is significantly reduced, which limits the scope of application of its products. At present, the existing solutions are usually to add asphalt polymer waterproof emulsion, paraffin wax waterproof emulsion, externally coated with silicone waterproof liquid, and add a certain amount of Portland cement, lime and other inorganic materials to improve the water resistance of gypsum blocks. However, adding the above-mentioned organic emulsion, affected by the emulsifier,...
