Abstract
The invention discloses a humidity-sensitive chromic functional material and a preparation method thereof. The humidity-sensitive chromic functional material comprises the following components in parts by weight: 100 parts of polymer resin, 100-200 parts of honeycomb-shaped calcium carbonate, 20-50 parts of a chromogenic agent, 5-10 parts of a color-developing agent and 1-5 parts of a desensitizer. The humidity-sensitive chromic functional material has the beneficial effects of corrosion resistance, thermal insulation and adiabaticity and inexpensive production cost, can be repeatedly used, is convenient to prepare and has larger industrial implementation prospects; the humidity-sensitive chromic functional material can be prepared into a solid device as desired and placed in a to-be-detected environment, when the humidity of the environment changes, the color of the solid device also changes.
Description
Technical field
The present invention relates to a kind of material causing the colour-change of material due to ambient moisture change.
Background technology
Humidity in order to the Conservation environment to Working environment and material is monitored and is regulated, and conventional way is detected by wet bulb thermometer.
But in many occasions, conventional wet bulb thermometer is difficult to be competent at, as high temperature occasion with have in the environment of etchant gas, be difficult to be detected by instrument.
Existing moisture-sensitive allochromatic material is a kind of hidden lid, technique of display, and there are materials many, display effect is poor, and range of application is restricted waits deficiency.
Chinese Patent Application No. 01112837.2 discloses a kind ofly meets functional materials of wet variable color and preparation method thereof.The present invention's chromogenic reagent, developer, desensitizer, binder composition moisture-sensitive allochromatic material.Chromogenic reagent is supplied for electronic leuco dye, and it is variable color after confessing electronics; Developer is awarded electronics, makes leuco dye color development; Desensitizer is water-soluble high-molecular compound, and it intercepts electric transmission conditionally; Binder is can not by the water base binder of water redissolve.
Above-mentioned patent is a kind of coating, needs load on specific carrier, can realize the function of meeting wet variable color, is unfavorable for using.
Summary of the invention
