Abstract

The invention discloses a lightweight plastering gypsum interface agent and its application. The light plastering gypsum interface agent of the present invention is composed of the following parts by mass: 20-40 parts of acrylic emulsion, 3-6 parts of nano-silicon dioxide, 45-55 parts of water and 5-8 parts of SBS fibers. The lightweight plastering gypsum interface agent of the present invention can repair the pores of the base layer well, improve the strength of the base layer, and at the same time form a flexible protective layer, form a plastering layer on the light plastering gypsum, and generate stress and strain on the plastering layer or the base layer. The flexible protective layer can buffer stress and strain and prevent the plastering layer from cracking. The finally prepared product is environmentally friendly, odorless, has good crack resistance, and has thermal insulation effects, and is especially suitable for the use of base leveling with large deviation of wall flatness.

Description

technical field [0001] The invention belongs to the field of building construction materials, and relates to a lightweight plastering gypsum interface agent and application thereof. Background technique [0002] For larger walls, in order to improve the construction efficiency, machine spraying is often used to speed up the construction. However, during the machine spraying operation, the spraying of light plastering plaster is completed at one time. Due to the participation of compressed air in the spraying, the gypsum mortar contains a large amount of When the gypsum mortar leaves the spray gun and reaches the wall, the compressed air cannot escape completely. After being sprayed onto the wall, the air is locked in the dry mortar due to the high viscosity and strong agglomeration of the gypsum mortar. , it takes a certain time to remove, and a large number of air bubbles and "pinholes" will be generated during the process of discharge. [0003] Even if the machine spray m...
