preparation example Construction

[0021] The preparation method of the above-mentioned high-speed hot stamping and hot stamping back glue for round pressing and round pressing has the following steps:

[0022] Step 1: First put all the solvents into the reaction kettle according to the proportion required by the formula, and heat to 40-50°C;

[0023] Step 2: Under stirring conditions, sequentially add the solid resin in the ratio required by the above formula;

[0024] Step 3: After the solid resin is completely dissolved, add additives;

[0025] Step 4: Continue stirring until the additives are evenly dispersed, stop stirring, cool to room temperature, weigh and pack, and obtain the product.

[0026] The first aspect of the present invention is that it has good adhesion, and has good wettability to some hot stamping substrates with low surface energy, and the system has good initial adhesion and stickiness to various smooth and rough surfaces. Resins with different softening points in the system have good c...

Embodiment 1

[0028] A kind of high-speed hot stamping and hot stamping back glue for round pressing and its preparation method. Weigh each component according to the proportioning ratio. When preparing, first put 30 kg of ethyl acetate and 40 kg of toluene into the reaction kettle and heat it to 50 °C Then, under constant temperature stirring condition, add 15 kilograms of acrylic acid copolymers, 12 kilograms of petroleum resins, and 8 kilograms of chlorinated polyolefin resins successively; after the solid resin is completely dissolved, add 5 kilograms of additives; continue to stir for 2 hours until the additives are evenly dispersed , stop stirring, cool to room temperature, and finally weigh and pack to obtain the product.

Embodiment 2

[0030] A kind of high-speed hot stamping back glue for round pressing and round pressing and its preparation method. Each component is weighed according to the proportion. During the preparation, 40 kg of methyl ethyl ketone and 50 kg of toluene are first put into a reaction kettle and heated to 50 °C; Under constant temperature stirring conditions, add 13 kg of EVA solid resin, 18 kg of rosin resin, 10 kg of petroleum resin, and 12 kg of chlorinated polyolefin resin in turn; after the solid resin is completely dissolved, add 7 kg of additive; continue stirring for 2 hours until the additive Disperse evenly, stop stirring, cool to room temperature, and finally weigh and pack to obtain the product.

[0031] The present invention is a bronzing adhesive capable of high-speed hot stamping and wide adaptability to substrates, and has good cutting performance; the present invention is suitable for ordinary paper, composite paper such as OPP and PET, UV glazing paper, etc. It has goo...

Abstract

The invention relates to a circular-to-circular high-speed hot gold stamping gum comprising the following components in weight ratio: 15-30 of acrylic copolymers, 10-20 of rosin resin, 10-20 of petroleum resin, 5-15 of chlorinated polyolefin resin, 10-20 of EVA (Ethylene-Vinyl Acetate) solid resin, 5-10 of additives and 70-90 of organic solvents. The circular-to-circular high-speed hot gold stamping gum has better adhesive force and good wettability for some hot stamping substrates with lower surface energy, the system has favorable initial adhesive force and holding power for various smooth and rough surfaces and has excellent hot stamping and edge scrapping performances, and different resins in the system have better compatibility; and the circular-to-circular high-speed hot gold stamping gum has a better stamping property for various substrates such as common untreated paper, composite paper, parts of UV (Ultraviolet) glazed paper and the like, and is suitable for circular-to-circular high-speed hot stamping, flat-to-flat hot stamping and circular-to-flat hot stamping, favorable in edge scrapping property and adhesive force, good in glossiness, integral in hot stamping, free of leak stamping and gold flying, good in hot stamping integrity for some rough substrates, wide in application range and strong in generality.

Description

technical field [0001] The invention belongs to the technical field of adhesive production, and relates to a high-speed hot stamping hot stamping adhesive for round pressing. Background technique [0002] Due to its unique superior artistry and exquisite effect, hot stamping is favored by people in the fields of printing and packaging, anti-counterfeiting packaging and other fields. With the rapid development of printing and packaging industry, hot stamping technology has been continuously improved and improved. Therefore, hot stamping is more and more widely used. , the dosage is also increasing, and the production efficiency is also required to be higher and higher. The effect of the original flat pressing and round pressing methods of hot stamping gradually fails to meet people's requirements. The round hot stamping method has the advantages of fast hot stamping speed and good hot stamping effect, and has been recognized and adopted by people. However, the high-speed hot ...
