Abstract
The invention provides adhesive with indicating function. The adhesive with the indicating function is prepared by heating water to between 40 and 60 DEG C, adding polyvinyl alcohol into the water, heating the mixture till boiling to dissolve the polyvinyl alcohol, cooling the mixture to room temperature, adding sodium carboxymethylcellulose into the mixture, dissolving the sodium carboxymethylcellulose with stirring, continuously heating the mixture to between 40 and 50 DEG C, adding swelling gelatin into the mixture, stirring the mixture uniformly, adding glutaraldehyde into the mixture, stirring the mixture for 10 to 20 minutes, cooling the mixture to room temperature, then adding ethanol solution of triarylmethane leuco dye into the mixture, and adding sodium hydroxide solution into the mixture. The method has the advantages of simple and feasible preparation process, low cost and easy production; and the adhesive has the most prominent characteristics that the color of the adhesive can indicate the adhered part so as to reduce the waste of repeated coating, the color of the adhered part can fade in short time, and no trace is left.
Description
Technical field
The present invention relates to a kind of Chemical Felter, specifically is a kind of binding agent with deixis.
Background technology
The binding agent of present industrial production is many based on colourless, in use can bring unnecessary waste because of repeatedly smearing.Along with the diversified demand of people to the binding agent color, some enterprise has produced colour adhesive, but used pigment can stay color at the first-class bonded position of paper, can not satisfy people's common requirements.And the allochroic solid of CN101608103A report, though can solve the problem of fading, the main component of binding agent is a polyvinylpyrrolidone, and cost of manufacture is improved greatly.
Summary of the invention
The purpose of this invention is to provide a kind of cost of manufacture lower have binding agent of deixis and preparation method thereof.
A kind of binding agent provided by the invention with deixis, by weight percentage:
Water 65～85
Polyvinyl alcohol 5～15
Xylo-Mucine 4～12
Gelatin 2～8
The glutaraldehyde 0.5～10 of 25-50%
Triaryl methane leuco compound dyestuff 0.1～1
Ethanol 0.5～2
The sodium hydroxide solution 0.04～5 of 2-8%
Essence 0～1.
Described triaryl methane leuco compound dyestuff is thymolphthalein or phenolphthalein; Described essence such as styracin.
Preparation method with binding agent of deixis provided by the invention comprises the steps:
1) take by weighing gelatin, according to the above ratio, with equivalent water logging bubble, swelling is standby;
2), take by weighing triaryl methane leuco compound dyestuff, use dissolve with ethanol, standby;
3), take by weighing other raw material, surplus water is heated to 40-60 ℃, add polyvinyl alcohol, stirring also is warming up to boiling, and it is fully dissolved, and is cooled to room temperature, add Xylo-Mucine, constantly stir and make dissolving fully, continue to be warming up to 40～50 ℃, add step 1) swelling gelatin, stir, add glutaraldehyde, stirred 10-20 minute, be cooled to room temperature, adding step 2) ethanolic soln of prepared triaryl methane leuco compound dyestuff, add sodium hydroxide solution then, stir, promptly get binding agent with deixis.
After adding sodium hydroxide solution, also can add an amount of essence in the described step 3).
Compared with prior art, the present invention has the following advantages:
1, binding agent of the present invention has deixis, can effectively locate and paste the position, reduces excessively in the binding agent use to smear the waste that is brought.
What 2, binding agent presented is blue or red, can take off within a short period of time, and it is residual that the stickup position does not have color.
3, with glutaraldehyde as condensing agent, the condensation ability is obviously improved, also can avoid the harm of using formaldehyde to bring in a large number.
4, the present invention fills a prescription simply, and cost is low, is easy to mass production.
