Abstract

The invention belongs to the technical field of building materials, and particularly relates to gypsum mortar with high water resistance. The gypsum mortar is prepared from the following raw materials: 850 parts of gypsum powder, 100 parts of vitrified microbeads, 50 parts of cement, 2 parts of a retarder, 2 parts of a water-retaining agent, 2 parts of a lubricant, 1 part of a stabilizer, 1.5 parts of an air entraining agent, 1 part of a water reducing agent, 5 parts of silicon dioxide and 2 parts of a water repellent. According to the gypsum mortar, through a chemical reaction and physical action of silicon dioxide and the water repellent, the strength and water resistance of the gypsum mortar are improved, by adding the vitrified microbeads, the heat preservation and insulation performance of the gypsum mortar is improved, noise transmission is reduced and the sound insulation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a gypsum mortar with strong water resistance and a preparation method thereof. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials and water. It is also called mortar and mortar. Commonly used mortars include cement mortar, mixed mortar lime mortar and clay mortar. [0003] Most of the existing gypsum mortars are not water-resistant, and have relatively large limitations in use. There are also a few gypsum mortars added with high-grade waterproof materials, but this type of mortar forms a layer of water-resistant film on the surface of the mortar, and the water resistance of the device will decrease. Gradually weakened with the passage of time, and the waterproof performance is relatively poor. Therefore, a gypsum mortar with strong water resistance and i...
