Abstract

The invention relates to a preparation method of a printable pre-coated film. The preparation method comprises the following steps: adding deionized water, an emulsifier, a part of monomers and a cross-linking agent into a single-neck flask according to requirements of a formula, and carrying out high-speed stirring for 30 minutes at normal temperature to obtain a pre-emulsion for later use; fullymixing the residual monomers for later use in a four-neck flask provided with an agitator, a thermometer and a reflux condensing tube; adding a certain amount of deionized water, carrying out heatingto 70 DEG C, adding 10% of the pre-emulsion and 1/2 of an initiator solution, and carrying out heating to 82 DEG C; after blue light appears in the emulsion in a reaction bottle, continuously dropwise adding the residual pre-emulsion, the mixed monomers and the initiator solution within 2-3 hours; after completion of dropwise addition, keeping the temperature for 1 hour, and then carrying out cooling to a temperature below 50 DEG C; adjusting a pH value to 7-8 by using ammonia water, and adding auxiliaries such as a wetting leveling agent and the like to obtain a double-sided adhesive layer;subjecting the double-sided adhesive layer to coating operation on a coating machine, and coating the surface of a pre-coated film with the double-sided adhesive layer by using an anilox roller; and carrying out drying by using a drying oven and performing rolling, wherein a product obtained after coating processing is the printable pre-coated film.

Description

technical field [0001] The invention relates to the field of precoating films, in particular to a printable precoating film and a preparation method thereof. Background technique [0002] The pre-coated film of printed matter is widely used in the field of packaging and printing, such as the surface processing of book covers, brochures, advertising posters, various cards, gift bags, and high-end packaging boxes. The traditional pre-coating film cannot be printed directly, it can only be printed on paper first, and then covered with the pre-coating film as a whole, and subsequent UV varnishing, printing and beautification cannot be carried out. Therefore, it is urgent to solve the existing problems. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a printable pre-coating film and a preparation method thereof, so as to achieve the purpose of effectively applying UV ink on the pre-coating film...
