Problems solved by technology

However, the self-leveling mortar has very strict requirements on the formula and construction of the mortar, otherwise it will cause empty drums, cracks and sand on the ground, so that the self-leveling mortar will lose the flatness of the surface and cannot produce self-leveling
Moreover, the self-leveling mortar currently on the market has high requirements on the bottom surface of the construction base, and the surface needs to be treated before the self-leveling mortar is applied, otherwise the bonding performance between the mortar and the base surface will be weakened, the operation is complicated, and the mortar The surface is easily polluted by grease, etc., and the surface of the mortar needs to be treated again after construction. The process is complicated, and the added glass sand cannot match the composition of the mortar, and it is easy to precipitate

Abstract

The invention provides dry-mixed self-leveling mortar and a preparation method thereof. The glass sand in the machine-made sand is fine sand made of waste glass products, resource waste is reduced, the surface of the glass sand is modified and protected, and the glass sand has good workability in mortar. Lithium-based bentonite and sepiolite powder in the surface modifier have certain expansibility, so that the shrinkage rate of the mortar can be reduced. And the modified retarder delays the coagulation time and reduces the shrinkage phenomenon in the coagulation process. In the mortar, the effect of bonding with a base plane is also achieved, and the excellent bonding performance is achieved. A modified leveling agent is added, so that the active ingredients in the mortar are effectively prevented from being flocculated and agglomerated, the mortar can be self-leveled, meanwhile, micro-pores on the surface are sealed, the surface of the mortar is not easily polluted when encountering oil stains, and the anti-pollution capability of the surface of the mortar is improved.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a dry-mixed self-leveling mortar. Background technique [0002] Waste glass is one of the most difficult components of municipal waste. If waste glass is not recycled, it is not conducive to waste reduction. The cost of collection, transportation and incineration is also high, and they cannot be degraded in landfills. Some of them even contain heavy metals such as zinc and copper. Random disposal will pollute soil and groundwater. The profit of recycling waste glass is meager, which is like a "chicken rib" compared to other recyclables. my country's waste material recycling industry has developed rapidly, and a recycling and processing system for renewable resources has basically taken shape. However, a small part of the waste glass produced in daily life is recycled at the waste collection station through various means, and most of the rest is landfilled by the sanitation dep...
