Abstract
Moistrure sensitive allochromic coating belongs to the textile chemistry science and technology field.
Coating of the present invention is made by wet sensitive colour changing body, sensitizing agent, toner, membrane-forming agent, is mainly used in the stamp of the textiles of non-dress property such as curtain wall paper etc., also can be used for the coating or the printing of wallpaper, picture, year calendar, the wet mark of commodity and other decorative articles.The feature of Moistrure sensitive allochromic coating is that its color can change with the increase and decrease of humidity in the air.
Description
The invention belongs to the textile chemistry science and technology field.Can be used for the stamp of the textiles of non-dress property and curtain wall paper etc., also can be used for the coated or the printing of wallpaper, picture, year calendar, commodity colour code and other decorative articles, also can be used for drawing.
The prior art data shows that various countries competitively develop allochroic paint, but all belongs to thermosensitive type, and minority is a Photosensitive.For example a kind of variable color clothes appears in the U.S. in recent years, and this clothes was a dusty blue originally, puts on person back because body temperature causes becoming incarnadine and green.But the photosensitive colour-changing character of this clothes only can be kept five months, thus only with dress before and after summer then, and wash resistant about 20 times only, it is not ideal enough and cost is high that such coating is used for functions of textile fabrics.
The object of the invention provides a kind of allochroic paint, and the pattern of printing with it can change and variable color with the humidity in the environment.Textiles and the printed matter printed with this coating not only can reach the purpose of beautify life, and have the function of weatherglass forecast weather concurrently, also can be used as the wet mark of commodity, and loss prevents to make moist.
The present invention is achieved in that basis slurry and toner compatibility that wet sensitive colour changing coating is made up of wet sensitive colour changing body, sensitizing agent, membrane-forming agent form.
Wet sensitive colour changing body Cocl

Toner chlorination phthalocyanine, azo orange, azophosphine, azophloxine etc.
Membrane-forming agent is butyl acrylate, methyl methacrylate and acrylamide copolymer emulsion 1., 2. polyvinyl alcohol series copolymer emulsion, 3. chitin emulsion, 4. methyl acrylate and butyl acrylate series copolymer emulsion (comprise add n-methylolacrylamide terpolymers), 5. 1. rubber latex etc. wherein being optimum.
At first prepare basis slurry with above-mentioned raw materials, its proportioning is,
Cocl

2The CP Beijing Chemical Plant produces 4～5%
Butyl acrylate, methyl methacrylate and
The acrylamide copolymer emulsion, trade name is
Tackiness agent SH-821, the auxiliary reagent factory, Shenyang produces 58～62%
Be mixed with coating with the basis slurry with toner again, toner is a GB group chlorination phthalocyanine, OB group azo orange, YG organizes azophosphine, and PN organizes azophloxine, and the different add-ons of color are 0.5～3% as requested, accurately take by weighing raw material and drop into agitator, stirred 1～2 hour, and made the slurry uniform mixing not have solids and get final product, be finished product after filtering.
This coating has four variable color series
Blue ()/() of 1 GB group ash is pea green
2 OB group coffee ()/() is orange red
Yellow in 3 YG group emerald green ()/()
4 PN group dark purple ()/() rhodo
Quite Munsell stratographic standard is

4,5YR district/lightness 5 chromas 4 ()/() 2.5R district/lightness 7 chromas 8
Color change interval is RH90～50%, and the condition that causes this coating color-changing is a humidity but temperature also plays katalysis, so more complicated.For example PN group coating is green rust when 33 ℃ of relative humidity 55% and temperature, when relative humidity reaches 65% and then be light green during 31 ℃ of temperature, when humidity increases again, change into baby pink, and relative humidity was reduced at 52% o'clock, when even temperature drops to 29.5 ℃, still be green rust.
The advantage of coating of the present invention is that the variable color contrast is big, has reversibility, and manufacture method is simple, and cost is low, about 20 yuan of per kilograms, and weather exposes to the open air in brown not more than 30,000 hours in environment, can high temperature resistant organic solvent washing.Can be made into the changeable color printing slurry, be used for the changeable color printing of textiles, print with plain net or rotary screen printing machine, the oven dry of seal back, also available writing brush is manually drawn, and textiles is not subjected to the restriction of fiber species, wherein relatively is applicable to decorative fabric.Except that textiles, also can be used for paper, plastics etc. are made basic thing and are printed or draw.
Below in conjunction with embodiment the present invention is described in further detail.
One, makes the basis slurry earlier
The basis slurry is by cobalt chloride (Cocl
26H
2O) and hexamethylenetetramine (C
6H
12N
4) form the wet sensitive colour changing body, both consumptions are respectively 17.78% and 16.67%.Though this discoloration member has the wet sensitive colour changing effect, the sensitization degree is low, must add sensitizing agent urea (CH
4ON
2) 4.46%, after the three was mixed, pulping stirred in butyl acrylate, methyl methacrylate and the acrylamide copolymer emulsion of adding 61.09%.
Two, make the Moistrure sensitive allochromic coating commodity, also claim the variable color slurry
Various toners and basis are starched in suitable ratio, and the variable color slurry that can be made into all kinds of different color change intervals is used for stamp.For example use the basis slurry of 0.17% toner (chlorination phthalocyanine) and 99.83% to mix and can be made into color change interval and be pea green variable color slurry (coating) commodity of blue ()/() of ash by vacuum filtration.The variable color that can be made into other color with quadrat method is starched, and asks for an interview table 1.
