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 accu

preparation example Construction

[0036] A kind of preparation method of water-based universal glue, is characterized in that, comprises the steps:

[0037] S1: First, add 35% of the total amount of polyacrylic acid emulsion into the stirring tank, and stir;

[0038] S2: Then add 25% VAE emulsion into the stirring tank and continue stirring;

[0039] S3: Then add 25% rosin emulsion into the stirring tank and continue stirring;

[0040] S4: Then add 15% polyurethane emulsion into the stirring tank and continue stirring;

[0041] S5: Finally, add 0.2% defoamer prepared in advance according to the total amount and continue stirring, then add 0.15% wetting agent and continue stirring, then add 0.3% thickener, stir until it is completely mixed, and finally add 0.15% flame retardant Just mix well.

[0042] The stirring time in the steps S1-S3 is 10 minutes, and the stirring time in the step S4 is 2.5 hours.

[0043] In the step S5, after adding 0.3% thickener, stir at 180 rpm for 40 minutes until the emulsion is...

Embodiment 1

[0044] Example 1, the main component of the universal glue on the market is neoprene or SBS, and generally benzene, toluene, dichloroethane, etc. are used as solvents, and organic volatile solvents account for more than 65%. Form accumulation, 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 chips cause many safety hazards in use, bringing serious harm to the human body and the ecological environment. Irreversible effects and hazards.

[0045] In conjunction with Example 1, the pure water-based universal adhesive of the present invention is water except for active ingredients (solid content of about 53%). And the effective substance of oily all-purpose adhesive is only 25~35%, all the other are organic volatiles (VOC) and account for more than 60% of total amount at least, seriously endanger human health and ecological environment. The ...

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...
