preparation example Construction

[0019] A method for preparing a card material dedicated to a laser printer, comprising the steps of:

[0020] (1) Preparation of adhesive solution: Add deionized water and ethanol with a weight ratio of 1:2 into a stainless steel bucket, stir evenly, then put in adhesive, continue stirring for 1 hour, start to heat up to 40°C and maintain 1 hour, then down to room temperature, the binder solution was obtained;

[0021] (2) Preparation of pigment slurry: adding the inorganic pigment and dispersant to the mixed solution of deionized water and ethanol with a weight ratio of 1:3, stirring, pre-dispersing and shearing dispersion, to prepare the pigment slurry;

[0022] (3) Prepare the toner receiving layer coating solution: mix the binder solution and the pigment slurry, add a curing agent and a wetting agent to prepare the toner receiving layer coating solution;

[0023] (4) Coating the toner-receiving layer coating solution on the upper surface of the film base, the coating meth...

Abstract

The invention relates to a special card sheet for a laser printer and a preparation method thereof. The special card sheet for the laser printer consists of a film base and a toner receiving layer, wherein the toner receiving layer is coated at the upper surface of the film base, the toner receiving layer is technically characterized by comprising an inorganic pigment and an adhesive according tothe weight ratio of 1:1-15:1, and the coating amount of the toner receiving layer is 5-25 g / m<2> based on dry weight. In the preparation method, coating liquid of the toner receiving layer is firstlyprepared and then is coated at the upper surface of the film base by using an extrusion coating mode. The invention has reasonable design and adopts the laser printer to directly print and form an image on the card sheet, greatly shortens the card-making time, reduces the card-making cost, enhances the card-making precision, improves the water-proofness, the wear resistance and the service life of the card and can be widely used for making various cards on site and making various personalized cards.

Description

technical field [0001] The invention belongs to the field of card making materials, in particular to a special card material for laser printers and a preparation method thereof. Background technique [0002] With the advent of the information age, there are more and more applications of various information recording materials, and cards have been widely used as a typical representative of information recording carriers. At present, the production of personalized cards (such as: PVC color portrait cards such as work permits, student permits, examination admission permits, temporary residence permits, driver's licenses, etc.) is mainly made of traditional inkjet printing materials. Due to problems such as poor performance, the service life of the card has been greatly limited. People are constantly looking for simple and fast ways to make certificates to adapt to the fast-changing information environment, and there are more and more requirements for on-site and personalized c...
