Problems solved by technology

The initial formaldehyde glue, oily glue, and starch glue are made of formaldehyde, organic solvents, and starch as the main raw materials. The residual formaldehyde in formal glue is difficult to remove, and it is difficult to meet environmental protection requirements. Oily glue has good performance, but Contains organic solvents that do not meet the requirements; starch glue has poor cohesive force, and it is difficult to meet the requirements of high-speed machinery after a short storage time; although the existing VAE emulsion glue has excellent performance, it still has poor initial viscosity and low bond strength , slow drying speed, which limit its wide application
These disadvantages have brought low production efficiency and increased defective rate, making it difficult to meet the needs of today's market

Embodiment 1

[0024] Add 60kg of VAE emulsion (805c of Beijing Dongfang Petroleum) into the reaction kettle at 20-30℃, turn on the mixer, add 3kg of nano-alumina, 1.5kg of calcium chloride, 5kg of polyvinyl alcohol, 8kg of alcohol, OP-102kg, and environmental protection agent TXIB 5kg, preservative Cathone 2kg, water 20kg, adjust the pH value, stir well and measure the viscosity. Packaging is the finished product.

Embodiment 2

[0026] Add 70kg of VAE emulsion (805c of Beijing Dongfang Petroleum) into the reaction kettle at 20-30℃, turn on the mixer, add 2kg of nano-alumina, 1.5kg of calcium chloride, 5kg of polyvinyl alcohol, 8kg of alcohol, OP-102kg, and environmental protection agent TXIB 5kg, preservative Cathone 2kg, water 20kg, adjust the pH value, stir well and measure the viscosity. Packaging is the finished product.

Embodiment 3

[0028] Add 65kg of VAE emulsion (805c of Beijing Dongfang Petroleum) into the reaction kettle at 20-30°C, start the mixer, add 2.5kg of crystal alumina, 1.5kg of calcium chloride, 3kg of polyvinyl alcohol, 6kg of alcohol, and 1.5kg of OP-10, 5kg of environmental protection agent TXIB, 1.5kg of preservative Kason, 15kg of water, adjust the pH value, stir well and then measure the viscosity. Packaging is the finished product.

Abstract

The invention relates to a water-based laser packaging glue used for cigarettes and a preparation method thereof. The water-based laser packaging glue consists of the following components: a VAE emulsion, nano alumina / crystal alumina, calcium chloride, polyvinyl alcohol, alcohol, a nonionic emulsifier, an environmental protection agent, a preservative, and water. Compared with the prior art, the water-based laser packaging glue has the characteristics of fast drying speed, strong cohesive force, good fluidity, no toxicity, no odor, no corrosion, no burning, and storage resistance. The productquality and various technical performance indicators are superior to similar products, especially in terms of drying speed, bond strength and fluidity, which can be increased by 60% based on the past.The water-based laser packaging glue strictly implements the requirements of the People's Republic of China tobacco industry standard-Volatile and semi-volatile components of tobacco water-based glue, formaldehyde is less than 20ppm, ethyl acetate is less than 400ppm, and the water-based laser packaging glue is inspected by the National Tobacco Quality Supervision and Inspection Center.

Description

technical field [0001] The invention relates to a packaging adhesive, in particular to a water-based laser packaging adhesive for cigarettes and a preparation method thereof. [0002] Laser holographic anti-counterfeiting (laser anti-counterfeiting) technology is internationally recognized as a promising anti-counterfeiting technology and a new type of anti-counterfeiting packaging material. It utilizes the peelable property of the laser-coated aluminum layer to transfer the laser-effected aluminum-coated layer to paper or other packaging materials through an adhesive to achieve a specific effect. Packaging glue plays an important role in this process. Background technique [0003] With the release of the latest tobacco water-based adhesive standards, the requirements for VOC control are higher, and higher requirements are put forward for the technical indicators of benzene and benzene series, phthalates, formaldehyde, and vinyl acetate. The residual amount of vinyl acetat...
