Abstract

The invention discloses anti-crack mortar and a preparation method thereof and relates to the technical field of construction mortar. The anti-crack mortar disclosed by the invention is prepared from light aggregate, cement, talc powder, wollastonite, asbestos powder, nut shell, kieselguhr, phenol-formaldehyde resin, polyester fiber and an anti-crack agent, wherein the anti-crack agent is prepared by mixing vegetable oil, carbon fiber and epoxy resin. The anti-crack mortar disclosed by the invention has relatively high bonding strength and compressive strength and excellent crack resistance while hollowing rarely occurs.

Description

technical field [0001] The invention relates to the technical field of building mortar, in particular to an anti-cracking mortar and a manufacturing method thereof. Background technique [0002] Anti-cracking mortar is made of polymer emulsion and admixture of anti-cracking agent, cement and sand mixed with water in a certain proportion, which can satisfy a certain deformation without cracking. In recent years, there have been many studies on anti-cracking mortar in my country, and it has been widely used in practical engineering. However, the existing thermal insulation mortar on the market still has the disadvantages of low strength and easy cracking after solidification. Contents of the invention [0003] The object of the present invention is to provide an anti-crack mortar and its production method, which can solve the problems of low strength of the anti-crack mortar and easy cracking after solidification. [0004] In order to solve the above problems, the technical...
