Abstract

The invention discloses a multifunctional gypsum painting ready mixed mortar as well as a preparation method and application thereof. The multifunctional gypsum painting ready mixed mortar comprises the following components: beta-semi-hydrated gypsum, heavy calcium carbonate, calcium hydroxide, quartz sand, methyl cellulose ether, adhesive, a phase-change material, modified starch, a dispersant, a gypsum shrinking resistant agent, lightweight calcium carbonate, barite powder, talcum powder, tourmaline powder and kieselguhr. The materials, such as kieselguhr, tourmaline, the barite powder, thephase-change material, and the like, are reaonsbaly used in the multifunctional gypsum painting ready mixed mortar; and it is proved that the multifunctional gypsum painting ready mixed mortar has various functions of automatic adjustment of indoor temperature and humidity, radiation resistance, bacterium resistance, air purification, and the like. In addition, the gypsum painting ready mixed mortar has higher anion generating amount and far infrared emissivity, can rapidly exhaust odor generated by products, such as paint, colloid, and the like and can exhaust smoke for a long term.

Description

technical field [0001] The invention relates to a ready-mixed mortar, in particular to a plaster ready-mixed mortar with multiple functions such as automatic adjustment of indoor temperature and humidity, radiation protection, antibacterial, and air purification. The present invention also relates to the multifunctional plaster pre-mixed mortar. The preparation method of mixed mortar and the application in the construction field belong to the field of ready-mixed mortar. Background technique [0002] The application of ready-mixed mortar in the field of construction originated in Europe at the end of the 19th century. It was produced by specialized manufacturers and used in various mortar mixtures in construction projects. It has a development history of more than 50 years. my country's development is relatively slow, but under the care and attention of the party and the country, especially after the 6 ministries and commissions issued the "Notice on Prohibiting On-site Mixi...
