Abstract

The invention discloses anti-cracking plastering mortar and a preparation method thereof, wherein the anti-cracking plastering mortar comprises an anti-cracking agent and plastering mortar; the mass of the anti-cracking agent is 1%-10% of the mass of the plastering mortar; the anti-cracking agent comprises 60%-95% of polymer composite fibers, 5%-10% of a surfactant and the balance of filler; the polymer composite fiber is formed by processing a resin-based composite material of a fiber reinforcement, and the polymer composite fiber is a composite fiber of which the surface of the fiber reinforcement is coated with at least one layer of resin. The anti-cracking plastering mortar disclosed by the invention is good in anti-cracking performance and good in durability.

Description

technical field [0001] The invention belongs to the technical field of plastering mortar, and in particular relates to an anti-cracking plastering mortar and a preparation method thereof. Background technique [0002] In the field of civil and construction engineering materials, there is a huge demand for fiber materials in construction mortar. Mortar is a kind of building material compounded with cement cementitious materials, mixed with certain sand, water and admixtures. It can be used for masonry, bonding, and plastering. However, it is often due to the hydration of cement during the hydration process. Shrinkage causes the mortar to crack after hardening, especially the plastering mortar. On the one hand, it reduces the protection of the plastering layer on the mortar base layer, and on the other hand, it causes the surface coating to crack and fall off. [0003] With the rapid development of my country's economy, resin-based composite materials with fiber reinforcement...
