Abstract

The invention discloses a water-based hot-cold tearing type transfer print release agent, which is prepared from the following ingredients in parts by weight: 30 to 50 parts of polydimethylsiloxane emulsion, 50 to 80 parts of acrylic ester, 5 to 7 parts of cross-linking agent, 12 to 24 parts of chitosan, 2 to 5 parts of gelatin, 2 to 3 parts o potassium persulfate, 12 to 19 parts of surface active agent, 11 to 20 parts of nano TiO2-SiO2 composite material, 8 to 15 parts of ethyl alcohol and 20 to 50 parts of deionized water. The release agent is a water-based release agent, has no toxin substance volatilization in a use process and avoids white precipitate in a storage process. Furthermore, the release agent can be peeled at high temperature and also can be peeled at normal temperature, and the release agent can be peeled completely, the stability is good, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of release materials, in particular to a water-based hot and cold tear transfer release agent and a preparation method thereof. Background technique [0002] Thermal transfer printing is a type of transfer printing. It is essentially a process of transferring the pattern or text on the thermal transfer film to the substrate through pressure and heat treatment. This process can be carried out because the hot melt adhesive is heated. The bonding force is greater than the bonding force between the release agent and the thermal transfer film substrate, so that thermal transfer occurs. Thermal transfer printing has been widely used, for example, in the surface decoration of book covers, calendars, greeting cards, and packaging printed matter. Thermal transfer printing has a wide range of applications. It can not only be hot stamped on the surface of printed matter and paper, but also can be thermally transferred...
