Problems solved by technology

However, the performance of casein glue with a single component cannot meet the requirements of high-speed labeling, and various additives must be added to modify it.
The raw materials of compound casein adhesives sold in the market are mostly casein produced from fresh milk, which is expensive and brings great cost pressure to the user unit, which is not convenient for market promotion

Embodiment 1

[0009] Add 630Kg of water into the reaction kettle with a heating reflux device, add 0.5Kg of emulsified silicone oil, 200Kg of yak milk casein, 3Kg of borax, 7Kg of sodium carbonate in turn, turn on steam heating, and react until the pH value is 6.0-7.5, and the casein is completely Dissolve, heat up to 60°C, add 30Kg of oxidized starch, 20Kg of polyvinyl acetate emulsion with a solid content of 40-50%, 100Kg of urea, 2Kg of hexamethylenetetramine, 8Kg of potassium sorbate, stir evenly, and cool down with cooling water , discharging, obtain product 1000Kg.

[0010] Borax and polyvinyl alcohol cannot be used at the same time.

Embodiment 2

[0012] Add 610Kg of water into the reaction kettle with a heating reflux device, add 1Kg of emulsified silicone oil, 180Kg of yak milk casein, and 9Kg of sodium carbonate in sequence, turn on steam heating, react until the pH value is 6.0-7.5, the casein is completely dissolved, and the temperature is raised to 65°C, add 60Kg of oxidized starch, 20Kg of polyvinyl alcohol solution with a solid content of 15%, 114Kg of urea, 1Kg of hexamethylenetetramine, 5Kg of potassium sorbate, stir evenly, pass in cooling water to cool down, and discharge to obtain 1000Kg of product .

Abstract

The present invent relates to a preparation method of a quick casein labeling binder which prepared from yak milk casein, polyvinyl alcohol, polyvinyl acetate, oxidized starch, ureophil, sodium carbonate, potassium sorbate, borax, silicone emulsion, hexamethylenetetramine and water in a reaction kettle, in a certain sequence and under a certain condition. The method has the advantages of simple preparation process and environmental protection, and the product has low cost, good stability, quick dry velocity, some water resisting property and easy elution, and thereby the method is particularly suitable for automatic and quick mechanical-labeling and has better application value.

Description

technical field [0001] The invention relates to a preparation method of an adhesive, in particular to a preparation method of a high-speed casein labeling adhesive. Background technique [0002] With the rapid development of my country's food and beverage industry, especially the beer and beverage industry, the speed of the automatic filling and labeling production line has been greatly increased, and the labeling speed has increased from the original 10,000 bottles per hour to 20,000-40,000 bottles or even 60,000 bottles. High requirements are put forward for labeling adhesives, and the original polyvinyl alcohol and starch-based adhesive products can no longer meet the needs. Casein adhesive has the advantages of non-toxic and tasteless, strong initial adhesion, good fluidity, and easy wash-off, etc., and is widely used. However, the performance of casein glue with a single component cannot meet the requirements of high-speed labeling, and various additives must be added t...
