Description

technical field [0001] The invention relates to the field of coatings, in particular to water-resistant interior wall putty powder and a preparation method thereof. Background technique [0002] Putty is a decorative material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. Applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. With the further improvement of people's requirements for home decoration, the development of putty also tends to be high-end, which not only requires good water resistance, crack resistance, and better affinity with the finish layer, but also its safety and environmental protection. put forward higher requirements. [0003] The Chinese patent document with publication number CN 104250466 A (application number 201410501645.3) discloses a water-resistant interior wall putty powder, which is composed of the following ra...
