Abstract

The invention relates to the technical field of gypsum mortar preparation, and particularly, relates to a moisture-resistant sound-insulation gypsum-based self-leveling mortar comprising a main material, an auxiliary material resin and an additive, wherein the auxiliary material resin is mainly a polyolefin elastomer, and the addition amount of the auxiliary material resin is 4-6 wt% of the weight of the main material. By optimizing the components of the mortar, adding the auxiliary material resin and controlling the addition amount, the moisture resistance of the mortar is improved, the defects that hollowing and cracking are prone to occurring are overcome, the weight is relatively small, construction is facilitated, the daily ground paving area can reach 800-1000 m<2>, and the foot feeling comfort is poor.

Description

technical field [0001] The invention relates to the technical field of gypsum mortar preparation, in particular to a moisture-resistant and sound-insulating gypsum-based self-leveling mortar. Background technique [0002] In recent years, with the improvement of people's material needs and the reduction of heavy physical labor, self-leveling mortar has gradually been favored by people. The construction efficiency of self-leveling mortar is extremely high, and it can accurately level the ground. Gypsum-based self-leveling mortar can be constructed in thick layers. It does not deform under the condition of thermal expansion and contraction, and is widely used in indoor floor heating projects and wooden floor installation projects; however, the water resistance of gypsum-based self-leveling mortar is poor, and the ground may appear strength cracking and corrosion when the ground is soaked in water or eroded by running water for a long time And so on. [0003] For this reason, ...
