Water-based all-purpose adhesive and preparation method thereof

Abstract

The invention discloses a water-based all-purpose adhesive and a preparation method thereof. The water-based all-purpose adhesive comprises the following components: a multi-component copolymerized acrylic emulsion, a VAE emulsion, a rosin emulsion, a polyurethane emulsion, a defoaming agent, a wetting agent, a thickening agent and a flame retardant. The preparation method comprises the following steps: firstly, adding 35% of polybasic copolymerized acrylic emulsion into a stirring kettle, and stirring; then adding 25% VAE emulsion into the stirring kettle, and continuously stirring; adding 25% of rosin emulsion into the stirring kettle, and continuously stirring; adding 15% of polyurethane emulsion into the stirring kettle, and continuously stirring; finally, 0.2% of the defoaming agent prepared in advance is added according to the total amount and continuously stirred, then 0.15% of the wetting agent is added and continuously stirred, then 0.3% of the thickening agent is added and stirred to be completely and uniformly mixed, finally 0.15% of the flame retardant is added and uniformly stirred, and the coating can be obtained. The coating has almost zero emission of VOC, is non-toxic, non-combustible and non-explosive and is easy to construct.

Description

technical field [0001] The invention relates to the technical field of super glue preparation, in particular to a water-based super glue and a preparation method thereof. Background technique [0002] Water-based universal adhesive is a pure water-based material mixed with multi-component copolymerized acrylate emulsion as the main body, supplemented with VAE emulsion, polyurethane emulsion, toughener, thickener, defoamer and preservative. The glue is convenient, environmentally friendly, energy-saving, safe and non-toxic, and replaces the commonly used solvent universal glue in the decoration and advertising industries and the lamination of industrial panels. At present, the domestic and foreign universal adhesive market is basically dominated by traditional solvent universal adhesives (commonly known as oily universal adhesives). Organic volatile solvents account for more than 65%. This highly toxic solvent can accumulate in the human body and cannot be completely excrete...

Problems solved by technology

At present, the domestic and foreign universal adhesive market is basically dominated by traditional solvent universal adhesives (commonly known as oily universal adhesives). The main components of this type are neoprene or SBS. Generally, benzene, toluene, dichloroethane, etc. Organic volatile solvents account for more than 65%. This highly toxic solvent can accumulate in the human body and cannot be completely excreted from the body through metabolism. Long-term exposure will cause various diseases and even cancer

In addition, ultra-high VOC emissions, flammable and explosive, and many potential safety hazards in use have brought serious and irreversible impacts and hazards on the human body and the ecological environment.
