Abstract

The invention discloses anti-cracking mortar and a preparation method thereof and relates to the technical field of building materials. The anti-cracking mortar is mainly prepared from cement, quartz sand, xonotlite, furnace slag powder, expanded slag beads, EVA re-dispersible latex powder, polysiloxane emulsion, calcium sulphoaluminate expansion agents, polypropylene fiber, polyimide fiber, glass beads, magnesium hydroxide, melamine water reducer, guar gum, citric acid and the like. The polysiloxane emulsion is added into the mortar, so that the hollowing resistance of the mortar is improved; through the calcium sulphoaluminate expansion agents and the polypropylene fiber, the shrinkage performance of the hardened mortar is improved, thus the cracking resistance of the mortar is improved; through the components such as magnesium hydroxide and glass beads and the like, the heat preservation performance and the performance stability of the mortar are improved; the produced mortar is high in overall performance and high in applicability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-crack mortar and a preparation method thereof. Background technique [0002] Mortar is made by mixing inorganic cementitious material with fine aggregate and water in proportion, also known as mortar. For masonry and plastering projects, it can be divided into masonry mortar and plastering mortar. The former is used for masonry and component installation of bricks, stones, blocks, etc.; the latter is used for walls, floors, roofs and beams. Plastering of the surface of the column structure, etc., to meet the requirements of protection and decoration. Some of the ordinary mortar materials are gypsum, lime plaster or clay mixed with fibrous reinforcing materials and water to prepare a paste, which is called ash, paste, mud or cement. Commonly used are hemp knife ash (lime plaster mixed with hemp knife), paper ash (lime plaster mixed with paper rebar), gypsum as...
