Abstract

The invention provides an adhesive for a gypsum-based light board and a preparation method of the adhesive. The adhesive for the gypsum-based light board comprises, by mass, 40-75 parts of calcium-magnesium powder, 24-50 parts of flue gas desulfurization gypsum, 0.8-7.5 parts of carboxymethyl cellulose, 0.2-2.5 parts of retarder and 0.1-0.5 part of a binding agent. The gypsum-based light board is high in bonding strength, good in stability and water-retaining property, environmentally friendly and easy to construct. The preparation method is simple, easy to implement and free of pollution. The adhesive for the gypsum-based light board is easy to construct, high in bonding strength and short in condensation time, can guarantee smooth construction, and guarantees the duration of a project.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a binder for gypsum-based lightweight boards and a preparation method thereof. Background technique [0002] Under the prior art, when the gypsum-based light-weight board is to be fixed on the wall, it is usually achieved by nailing or using adhesives such as glass glue, liquid glue, and bonded plaster. The above-mentioned construction methods not only have complicated construction procedures, but also have low bonding strength of the boards, and also have the defects of pollution and environmental protection. In the above-mentioned pasting method, the adhesive used causes environmental pollution and at the same time brings invisible harm to the construction personnel's body, and the setting time of the adhesive is too long, which affects the construction progress and brings adverse effects on the project. Contents of the invention [0003] The present invention aim...
