Abstract

The invention discloses a hot-stamping aqueous release agent. The hot-stamping aqueous release agent is prepared from the following components in parts by weight: 10-15g of hydroxyl-terminated polydimethylsiloxane, 20-30g of a potassium hydroxide solution, 5-10g of hydrogen-containing polymethylsiloxane, 15-25g of acetate starch, 25-30g of paraffin, 20-30g of emulgators, 5-10g of a defoaming agent, 4-6g of an anticorrosion agent and 80-100g of deionized water. The hot-stamping aqueous release agent is simple to prepare and reasonable in formula. According to the hot-stamping aqueous release agent, a silicon-containing surfactant is mixed with an OP-10 emulgator and an OS emulgator, the hot-stamping aqueous release agent has high compatibility with organosilicon products; the problem that the organosilicon products are difficultly emulsified is solved; when the emulsification temperature reaches 85-95 DEG C and approaches the boiling point of the water, the emulsification efficiency isgreatly improved, and the production efficiency is improved; a paraffin emulsion synthesized by the hot-stamping aqueous release agent is used as gluing of the release agent; the corrosion resistanceof the paraffin emulsion is higher than that of an S-8 imported paraffin emulsion; the raw materials of the hot-stamping aqueous release agent are free of pollution, so that the pollution to the environment is avoided.

Description

technical field [0001] The invention belongs to the technical field of food, and more specifically relates to a water-based release agent for hot stamping. Simultaneously, the invention also relates to a preparation method of a water-based release agent for hot stamping. Background technique [0002] The release agent is a low-density transparent liquid with wax and silicone resin as the main body. It maintains a solid state at room temperature and is an oily substance that melts and flows at a certain temperature (about 150°C). It acts as a buffer for PE. The adhesion between the film and the transfer layer or the printing layer, and the abrasion resistance of the paint, can protect the color ink, the radiation intensity of ultraviolet rays, reduce the invasion of the ink by adverse factors in the air, and prolong the service life of the ink. , that is, to enhance the durability of colored inks. Most of the current release agents are used in mold release, release paper co...
