Problems solved by technology

However, starches have poor initial viscosity, slow curing time, and are prone to mildew; polyvinyl formals will release formaldehyde, which is harmful to humans, and affect people's health; although casein glue has good water resistance, strong initial viscosity, and long curing time Fast, good mobility and other advantages
But now the market price of casein is as high as about 45,000 yuan per ton, causing the cost of casein gum to reach more than 10,000 yuan per ton. The increase in product cost directly affects the economic benefits of the manufacturer, causing the popularization and application of this product to be limited. influences

Embodiment 1

[0016] A water-resistant and environmentally friendly label adhesive, the components of which are proportioned by weight: polyvinyl alcohol: 150kg, acrylic acid: 35kg, butyl acrylate: 5kg, styrene: 10kg, acrylamide: 12kg, ammonium persulfate: 1kg, bicarbonate Sodium: 18kg, water: 1000kg. Its production method is to add polyvinyl alcohol to water and stir and heat slowly to dissolve the polyvinyl alcohol, then cool down to 70°C and add ammonium persulfate, acrylic acid, butyl acrylate, styrene and acrylamide mixture; then slowly heat up to 80°C -90°C, keep warm for 1-2 hours, then add sodium bicarbonate and stir for 15 minutes, adjust the pH to 7-8, and finally cool down and discharge.

Embodiment 2

[0018] A water-resistant and environmentally friendly label adhesive is formulated by weight: polyvinyl alcohol: 180kg, acrylic acid: 40kg, butyl acrylate: 6kg, styrene: 12k, acrylamide: 5k, ammonium persulfate: 1.2kg, sodium bicarbonate: 19kg , Water: 1000kg. The production method is to add polyvinyl alcohol into water, stir and heat slowly to dissolve the polyvinyl alcohol, then cool down to 70°C, add ammonium persulfate, acrylic acid, butyl acrylate, styrene, and acrylamide mixture, and then slowly heat up to 80- 90°C, heat preservation reaction for 1-2h, add sodium bicarbonate and stir for 15min, adjust pH=7-8, finally cool down and discharge.

Abstract

The invention relates to a water-resistant adhesive and its production method. It is composed of water, PVA, acryl acid, butyl acrylate, acrylamide, styrene, ammonium, persulfate, NaHCO3. It is produced by: initiating monomer with an initiator in a PVA-water solution. The process is simple and cheap. The production doesn't discharge harmful wastes.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a method for preparing water-resistant and environment-friendly label glue for bottled products. Background technique [0002] Trademark adhesives have always been an important link in the appearance and image of product packaging. They are widely used in beer, liquor, canned food, medicine, pesticides, chemical reagents and other industries. Different packaging materials, different production speeds and other conditions have different effects on adhesives. Requirements, especially for the beer production industry, first of all, it must have high viscosity, good fluidity, strong initial viscosity, and short curing and drying time; secondly, it must have certain mildew resistance and water resistance, and it will not mold in a humid environment. The label will not drop in ice water or refrigerator; at the same time, the recovery bottle should be easy to clean under certain conditions. ...
