The chalking-resistant spraying adhesive belongs to the technical field of adhesives.

Description

technical field [0001] The invention discloses an adhesive, specifically, a powdering-resistant spraying adhesive. The invention also discloses a preparation method of the powdering-resistant spraying adhesive for walls, which belongs to the technical field of adhesives. Background technique [0002] Adhesive bonding (bonding, bonding, cementation, gluing) refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives, which has the characteristics of continuous stress distribution, light weight, or sealing, and low temperature in most processes. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is the fastest growing in modern times, with a wide range of applications, and has a major impact on the progress of high-tech science and technology and the improvement of people's daily life. Therefore, it is very important to research, d...
