Problems solved by technology

[0005] At present, the resin used for water transfer tearable film is mainly imported solid acrylic resin with a molecular weight of 120,000 to 160,000. Its glass transition temperature is 30 to 55°C and the resin has high hardness. Plasticizer, so it is easy to cause brittleness and difficult to release the film due to the volatilization of the plasticizer when transferring at a high temperature of 180°C or above, so it is generally only suitable for preparing tearable films for normal temperature transfer printing, and it is difficult to be used as (high-efficiency) 180 Tearable film for high temperature transfer printing at ℃ or above
In addition to the above-mentioned shortcomings, domestic solid acrylic resins also have the disadvantages of easy agglomeration of the resin, low molecular weight and wide range, and are generally dissolved with aromatic hydrocarbons, alcohols, and ether solvents before use, and the obtained resin solution has high viscosity and strong odor; Slow, the heat resistance of the film is poor, and it is difficult to meet the requirements of high hardness and good tensile strength at the same time, and the film is easy to stick back in summer and brittle in winter, and the tearable film is not stiff enough to be attached to curved objects such as wine bottles Not enough
In addition, the solid resin synthesized by the emulsion suspension polymerization process will produce a large amount of wastewater containing unconverted monomers and small molecules in the synthesis and washing process; the solid resin synthesized by the bulk polymerization process has low conversion rate and strong odor
These are not good for the environment and occupational health

Description

technical field [0001] The invention belongs to the field of resins, and in particular relates to a water transfer printing tearable film resin, a preparation method thereof and a water transfer printing tearable film composition. Background technique [0002] The water transfer tearable film is a film that is printed on the pattern to be transferred and then silk screen printed. After the tear-off film is printed, the "flower paper" is obtained. When the flower paper encounters water, the tear-off film carries the pattern and separates from the base paper, and then pastes it on glass, ceramics and other object materials. After a certain period of time at normal temperature or after baking at ≥ 180°C, the tear-off film is removed, and the pattern remains on the object. material, complete the transfer process. [0003] When screen-printing a tear-off film, it is required to have good screen printing performance, and can be baked into a film or dried naturally to form a film...
