AI Technical Summary

Problems solved by technology

At present, the dyne (dyne ratio surface tension) of the existing PVC card base material is relatively low. When printing, the ink adsorption force is not high, the permeability is weak, the printing effect is not good, the printing fastness is not ideal, and the fastness is not good when compounding. Well, prone to two-layer peeling

Abstract

The invention relates to a PVC card matrix material. The constituents in portion by weight of the card matrix material are: 80 to 20 portions of PVC resin, 80 to 20 portions of chloride-vinyl acetate resin, 1 to 6 portions of modified PVC resin, 1 to 2 portions of heat stabilizer, 1 to 2.5 portions of processing additive, 5 to 15 portions of titanium dioxide, 0 to 10 portions of nanometer calcium carbonate, 0.7 to 2.3 portions of lubricant, 3 to 12 portions of anti-impact modifier and 0.1 to 0.6 portions of bonding accelerator. The PVC card matrix material has a high dyne characteristic, and in printing process, the PVC card matrix material is strong in printing ink adsorption force and permeability, good in printing effect, printing color fastness as well as compounding fastness and difficult to peel.

Description

technical field [0001] The invention relates to a PVC card base material. Background technique [0002] With the continuous advancement of science and technology and the continuous application of new technologies, integrated circuit cards, magnetic stripe cards, bank cards and other cards based on PVC plastic cards are more and more widely used in transportation, medical care, finance, taxation, Customs, national security and many other fields. In addition to the characteristics of general PVC rigid sheet, the material for making card base should also have the characteristics of good printing effect, good fastness and good fastness when compounded. At present, the dyne (dyne ratio surface tension) of the existing PVC card base material is low. When printing, the ink adsorption force is not high, the permeability is weak, the printing effect is not good, the printing fastness is not ideal, and the fastness is not good when compounding. Well, the phenomenon of two-layer peel...
