Problems solved by technology

Yet the inventor thinks, some existing aluminosilicate polymers still have the following problems aspect crack resistance: 1. traditional aluminosilicates will imitate the method that cement enhances crack resistance to A certain proportion of rubber powder is added to the mortar, but this method will cause a decrease in the strength of the product
2. In addition to adding rubber powder, some fiber products, such as polymer fibers and mineral fibers, will also be added. The added fiber products are generally expensive and will increase production costs.

Abstract

The invention belongs to the technical field of aluminosilicate polymers, and in particular relates to a method for improving the crack resistance of aluminosilicate polymers, aluminosilicate polymers and applications. The aluminosilicate polymer comprises the following components by weight: 40-80 parts of mica powder, 400-480 parts of active aluminosilicate admixture, 45-56 parts of industrial caustic soda, 180-240 parts of water, 230- 252 parts of industrial sodium silicate, 400‑700 parts of sand. The method comprises the following steps: 1) uniformly mixing the mica powder and the active aluminosilicate admixture, then sequentially adding industrial caustic soda, water, and industrial sodium silicate to the obtained mixed powder and mixing to obtain a slurry; 2) The slurry in step 1) is maintained, and then sand and gravel are added to the slurry to mix and solidify to form. In the mica powder added in the aluminosilicate polymer of the present invention, in the aluminosilicate dissolution-polymerization reaction process, the K in the mica + is dissolved and forms K‑PS type aggregates on its surface, which significantly improves the crack resistance of aluminosilicate polymers.

Description

technical field [0001] The invention belongs to the technical field of aluminosilicate polymers, and in particular relates to a method for improving the crack resistance of aluminosilicate polymers, aluminosilicate polymers and applications. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Aluminosilicate polymer is a new type of building material, which is a hard block formed by aluminosilicate gel phase wrapped solid particles.
