Problems solved by technology

Nowadays, the commonly used plastering products are gypsum-based leveling products. The existing problems are poor water resistance, low strength, and softening after absorbing water, which will lead to mildew, swelling and peeling of the interior wall surface paint and putty.
On the other hand, most of the leveling products routinely used today are on-site wet-mix mortars. The existing problems are that they are not environmentally friendly, the construction dust pollution is large, and the on-site mixing ratio has no quality control and low strength; and the wet-mix mortar has single performance and poor construction. , poor crack resistance

Abstract

The invention relates to anti-cracking mortar powder for thin plastering and leveling of inner walls and a preparation method of the anti-cracking mortar powder. The anti-cracking mortar powder for thin plastering and leveling of inner walls is prepared from the following raw materials: in parts by weight, 17-25 parts of a cementing material, 0-10 parts of active filler, 0-5 parts of inert filler,70-75 parts of aggregate, 0.1-0.2 part of a water-retaining thickener, 0-0.8 part of an adhesive, 0-0.5 part of a binder, 0.2-0.3 part of a water-conducting thickener, 0.05-0.15 part of crack-resistant fiber, 0-0.5 part of a slipping agent and 0-0.1 part of a thixotropic agent. The mortar powder has good water resistance, high strength, no easy cracking, no indoor environmental pollution and goodworkability.

Description

technical field [0001] The invention belongs to the field of construction materials, and in particular relates to an interior wall thin plaster leveling anti-cracking mortar powder applied to the interior wall of a building and a preparation method thereof. Background technique [0002] After construction, the inner walls of the building are uneven and need to be leveled by plastering. Nowadays, the commonly used plastering products are gypsum-based leveling products. The existing problems are poor water resistance, low strength, and softening after absorbing water, which will lead to mildew, drumming and peeling of the interior wall surface paint and putty. On the other hand, most of the leveling products routinely used today are on-site wet-mix mortars. The existing problems are that they are not environmentally friendly, the construction dust pollution is large, and the on-site mixing ratio has no quality control and low strength; and the wet-mix mortar has single perform...
