Problems solved by technology

[0006] The existing mortar is prone to cracks during use, and its compressive strength is low, and it is easy to cause damage to the body during use. At the same time, the anti-seepage effect is long, and water easily penetrates into the mortar, which reduces the performance of the mortar. When used in a high temperature environment, there will be a problem of performance degradation

Abstract

The invention discloses macromolecular anti-crack waterproof mortar and a preparation method thereof. The macromolecular anti-crack waterproof mortar is prepared from the following raw materials in parts by weight: 100-200 parts of cement, 100-150 parts of sand, 30-50 parts of reinforcing filler, 1-4 parts of a high-efficiency water reducing agent and 100-150 parts of water. In the preparation process, a high-efficiency water reducing agent is prepared, the high-efficiency water reducing agent has a hydrophilic group sulfonic acid group and a hydrophobic group alkyl group, when the high-efficiency water reducing agent is added into cement mortar, cement particles can be dispersed, starch is used as a carrier, the strength of mortar is further improved, the reinforcing filler is prepared, and after the reinforcing filler is mixed with cement, the prepared mixed mortar contains a large number of silicon-oxygen bonds, the silicon-oxygen bonds are long in spacing, large in bond angle and large in bond energy, and polysilane chain segments are soft, so that the surface tension is small, and the mortar has good high temperature resistance and water repellency.

Description

technical field [0001] The invention belongs to the technical field of mortar preparation, and in particular relates to a polymer crack-resistant and waterproof mortar and a preparation method thereof. Background technique [0002] As we all know, cement mortar is an important building cementing material. It is usually silicate clinker made by mixing limestone, coal, iron powder and clay and other mineral materials, and then adding gypsum to the clinker and grinding become. In actual production, in order to ensure the strength of cement mortar, cement manufacturers use technical means to properly mix some mixed materials to achieve the purpose of saving mineral resources, reducing production costs and protecting the environment. The mixed materials are mainly some cheap slag, furnace Ash, fly ash, etc. [0003] The existing mortar is prone to cracks during use, and its compressive strength is low, and it is easy to cause damage to the body during use. At the same time, the...
