Abstract
A chromotropic paint with time indication function is prepared from pH indicating agent as chromotropic agent, solid alkali as promoter, acrylic resin or emulsion as film forming substance, and organosilicon resin as coating agent. The thickness of coated layer can be used to control the colour-change time. It can be used for the package of food to indicate the quality guarantee period of food.
Description
The present invention is a color with a time display function coating and its preparation method, which can over time at a certain temperature
Produce a variety of changes irreversible color change, that is a time - between the color corresponding to the color coatings.
This coating can be used for commodities (especially food) packaging labels, printed as images or text to display its shelf life,
Relative to the date of printing methods can better improve the appearance of the packaging sense and credibility.
The coating of the invention include discoloration agent, agent of change agents, film-forming material and coating agent.
Discoloration agent: It is a kind of molecular structure or composition changes when after the substance can produce color changes. Such as acid-base indicator, sensitive
Indicator.
Promoting change agents: agents can induce discoloration discoloration of the material. Such as acid or alkali can induce acid-base indicator color, iron ions can iron test
Agents discoloration, zinc ions can zincon discoloration.
Film-forming substance: Preparation of coating binders. Including (a) emulsion type: acrylic emulsion, white latex, vinyl acetate-acrylate emulsion: (2)
Solvent: acrylic resin, alkyd resin, epoxy resin.
Coating agents: the color agent and / or agent of change agent to coat granular appearance. The use of different coating material, the thickness of the non-coated
Same, the color change agent and promoting mutual penetration agent to control the speed. Thereby controlling the discoloration time. Cladding material selection principles:
(1) does not adversely affect the coating material, with no chemical reaction; (2) no adverse reactions with the film material. (3)
Have a certain porosity, that is coated with a permeable material.
The coating delay discoloration principle is: discoloration agent and agent of change agents constitute a reaction, once mixed color change will occur
Technology, but this discoloration occurs in a short time period. Therefore, the present invention is characterized by the use of some of the instantaneous color change right,
Their appearance will be separately coated particles, discoloration agent and agent of change agents must penetrate through the coating layer can migrate from contact with each other
The discoloration reactions. So we can by changing the type and thickness of the coating layer to control the color change speed in order to meet the food
Has a different shelf life requirements.
Coating agents include silicone resin, epoxy resin, polyurethane resin, etc., used in the present invention is a silicone resin coating agent.
Various discoloration agent and promoting behavior change agents discoloration in Table 1:
Table 1: discoloration agent and agent of change agent in the film-forming material in the color behavior
Note: at room temperature, to join the discoloration agent 0.2g and 4.0g resin uniform grind in a mortar, then add 0.4g of research to promote change agent, and then observe the
Color effects.
