Abstract
The invention provides a formula and a production method of high-tensile-strength plastering gypsum, and relates to the technical field of building materials. The high-tensile-strength plastering gypsum is prepared from the following raw materials in parts by weight: 50 to 60 parts of gypsum powder, 30 to 35 parts of purified water, 2 to 3 parts of tackifier, 10 to 13 parts of coarse whiting, 10 to 13 parts of slurry asbestos wool, 3 to 6 parts of vitrified microbeads, 10 to 20 parts of clay powder, 20 to 25 parts of lightweight aggregate, 30 to 35 parts of polypropionic acid resin, 5 to 15 parts of nano ceramic hollow microbeads and 2 to 6 parts of polyacrylamide. By adding the slurry forming asbestos wool and the vitrified micro bubbles into the plastering gypsum, the tensile strength and the heat insulation performance of the plastering gypsum can be improved, the flowability and the self-resistance strength of mortar are improved through the vitrified micro bubbles, the cohesiveness among all the materials is improved through the tackifier and the clay powder, and polyacrylamide is higher in cohesiveness and better in durability; therefore, the plastering gypsum is worthy of vigorous popularization.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a formulation and a production method of plastering gypsum with high tensile strength. Background technique [0002] With the rapid development of my country's market economy and the improvement of people's quality of life, people's expectations for the quality of building decoration are also getting higher and higher. In the construction of interior walls, traditional cement mortar and mixed mortar have poor water retention during hydration and drying. , the shrinkage rate is large, it is easy to cause common quality problems such as hollowing, cracking, and falling off of the wall surface, and its shortcomings such as slow setting and hardening and long decoration period are more likely to occur when the construction is not standardized, and the on-site repair rate is high, which is increasingly unable to meet indoor Plastering quality requirements and construction per...
