Polymer mortar and mixing method thereof

Abstract

The invention relates to polymer mortar. The polymer mortar comprises the following components in percentage by weight: 5.0-10.0% of fly ash, 0.3-0.8% of silicon powder, 0.5%-0.8% of redispersible latex powder, 0.2-0.3% of thickening and water-retaining agent, 0.8-1.2% of water reducing agent, 0.1-0.3% of coagulation accelerator, 0.1-0.2% of anti-crack fiber, 0.1-0.2% of wood fiber, 45.0-50.0% of quartz sand and 40.0-45.0% of cement. The invention also discloses a mixing method of the polymer mortar. The mixing method comprises the following steps: firstly stirring and mixing the fly ash, the thickening and water-retaining agent, the water reducing agent, the coagulation accelerator, the anti-crack fiber, the wood fiber, the redispersible latex powder and the silicon powder according to a proportion to obtain a mixture which is uniformly stirred; then weighing, mixing and uniformly stirring the mixture, the cement and the quartz sand to obtain the polymer mortar. By applying the technical scheme of the invention, the performance index parameters of the polymer mortar are as follows: the splitting tensile strength is 7.2MPa, the compressive strength is 58.8MPa, the flexural strength is 12.2MPa and the positive pulling bond strength is 2.5MPa.

Description

technical field [0001] The invention and the field of building materials particularly relate to a high-performance, high-strength structure-reinforced polymer mortar and a preparation method thereof. Background technique [0002] Mortar is widely used in daily life. [0003] The general polymer cement mortar currently used has the following deficiencies: (1) the general compressive strength is relatively low, and the seismic performance is not good; (2) the high compressive strength has low flexural performance, and the seismic performance is not good; (3) ) and epoxy mortar although the performance is better, but the price is high. [0004] The compressive strength of the existing plastering mortar is 20-30Mpa, and the flexural strength is 4-6Mpa; the compressive strength of the floor mortar is 50-60Mpa, but it has no cohesive force and cannot plaster the wall. Contents of the invention [0005] The first object of the present invention is to provide a kind of high-perf...
