Embodiment 1

[0033] Mix 20 parts of ethylene-acrylic acid copolymer, 15 parts of polyurethane resin and 61.4 parts of soft water, start heating and stirring, stir at 100r / min, 70°C and add 1 part of polycarbodiimide and 0.1 part of N-hydroxysuccinide Amine, continue to stir for 5 minutes, the temperature drops to 45 ° C, add 2 parts of heat-activated adhesive and continue to stir for 20 minutes, after cooling down to normal temperature, add 0.5 parts of nonionic antistatic agent under stirring to obtain a water-based coating solution. The water-based coating solution is used A 120-mesh anilox roller is coated on a medical wristband, and the sample is obtained after printing by HP Indigo. The printed appearance is good, the color is uniform, and the color difference is 0.45△E. The printed wristband is soaked in soft water and left for 7 days. It is whitish and has a good appearance.

Embodiment 2

[0035] Mix 25 parts of ethylene-acrylic acid copolymer, 20 parts of polyurethane resin and 47.6 parts of soft water, start heating and stirring, stir at 100r / min, 70°C and add 2 parts of polycarbodiimide and 0.4 parts of N-hydroxysuccinide Amine, continue to stir for 5 minutes, the temperature drops to 45 ° C, add 4 parts of heat-activated adhesive and continue to stir for 20 minutes, after cooling down to normal temperature, add 1 part of non-ionic antistatic agent under stirring to obtain a water-based coating solution. The water-based coating solution is used A 120-mesh anilox roller is coated on a medical wristband, and the sample is obtained after printing by HPIndigo. The printed appearance is good, the color is uniform, and the color difference is 0.37△E. White, good appearance.

Embodiment 3

[0037] Mix 30 parts of ethylene-acrylic acid copolymer, 30 parts of polyurethane resin and 29 parts of soft water, start heating and stirring, stir at 100r / min, 70°C and add 3 parts of polycarbodiimide and 1 part of N-hydroxysuccinimide Amine, continue to stir for 5 minutes, the temperature drops to 45 ° C, add 5 parts of heat-activated adhesive and continue to stir for 20 minutes, after cooling down to normal temperature, add 2 parts of non-ionic antistatic agent under stirring to obtain a water-based coating solution. The water-based coating solution is used A 120-mesh anilox roller is coated on a medical wristband, and the sample is obtained after printing by HP Indigo. The printed appearance is good, the color is uniform, and the color difference is 0.40△E. The printed wristband is soaked in soft water and left for 14 days. It is whitish and has a good appearance.

Abstract

The invention provides a coating liquid, comprising 15-30 parts by weight of polyurethane, 20-30 parts by weight of ethylene-acrylic acid copolymer, 1-3 parts by weight of polycarbodiimide, 0.1-1 part by weight of N- Hydroxysuccinimide, 2-5 parts by weight of heat-activated adhesive, 0.5-2 parts by weight of non-ionic antistatic agent and 25-65 parts by weight of water. The application also provides a composite medical wrist band. The invention provides a coating solution, which uses polycarbodiimide and N-hydroxysuccinimide as a crosslinking modifier, and N-hydroxysuccinimide makes polycarbodiimide form an active ester , to enhance the water resistance of the emulsion, and at the same time, the mixture of polyurethane and ethylene-acrylic acid copolymer and the heat-activated adhesive enhance the cohesion of the medical wristband, so that the printing of the wristband is firm and not easy to wear and fade; on the other hand, non- Ionic antistatic agents also protect medical wrist straps from static electricity.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a coating liquid and a composite medical wrist band. Background technique [0002] Medical wristband is a kind of wristband. Medical wristband is generally used to provide identification information of patients. Its content includes: name, gender, bed number, hospitalization number and other information specially required by medical treatment. It is mainly used by hospitals to identify patients. effective tool. All kinds of medical wrist straps on the market have the characteristics of simple use, firm buckle, comfortable wearing, various colors and novel and beautiful styles, and are widely used in hospitals of all sizes. [0003] However, the paper with patient information on the general medical wristband is easy to get wet when exposed to water, which makes the handwriting on the paper blurred, causes damage to the identification card, and is inconvenient to check, m...
