Abstract

The invention discloses an anti-cracking putty and a preparation method thereof, comprising the putty and an anti-cracking agent added to the putty, in terms of mass percentage: the mass of the anti-cracking agent is 3% to 9% of the mass of the putty; the anti-cracking agent includes: 60% to 90% of polymer composite fibers, 3% to 10% of surfactants, and the rest are fillers; the polymer composite fibers are processed by resin-based composite materials of fiber reinforcements, and the polymer composite fibers are fiber The surface of the reinforced body is coated with at least one layer of resin composite fibers. The anti-crack putty of the invention has good anti-crack performance and good durability.

Description

technical field [0001] The invention belongs to the technical field of putty, and in particular relates to an anti-crack putty and a preparation method thereof. Background technique [0002] The putty used for building interior is the base surface treatment material applied to the interior of the building before the decoration project, with the main purpose of leveling. The existing putty is easy to lose dust, cracks and peel off when it is applied to the wall. Putty is an important supporting material in the construction of architectural coatings, which will directly affect the coating effect of coatings. On the interior and exterior walls that have been applied with architectural coatings, surface cracks, peeling, and peeling are often found, which in turn affects the function and appearance of the building. A large number of facts show that in many cases these problems are caused by the quality of putty. Cracking is the most common putty defect, especially for exterior...
