Abstract
The invention provides a fadable coloured adhesive and a preparation method thereof. The preparation method comprises the following steps: firstly weighing raw materials in proportion, and using absolute ethanol to dissolve triaryl methane leuco dye; preparing a sodium hydroxide aqueous solution; and heating water, slowly adding sodium carboxymethylcellulose into water, dissolving, adding amylum, adding sodium alginate and polyacrylamide after the amylum is dissolved, stirring uniformly and adding the ethanol solution and sodium hydroxide solution of triaryl methane leuco dye, finally adding an antiseptic agent and essence to prepare the coloured adhesive and sealing. The coloured adhesive is lower in cost and environment-friendly, the color of the adhesive is stable and the coloured adhesive can completely fade after coating, and the bonding effect is good.
Description
Technical field
The present invention relates to a kind of cakingagent, a kind of coloured cakingagent and preparation method thereof that fades specifically, this coloured cakingagent can be used for the bonding of paper such as wallpaper, envelope etc.
Background technology
At present our cakingagent of using mainly with colourless be main, in the process that paper is smeared, owing to not seeing Chu, be prone to and smear inhomogeneous waste or the subregion of causing and smear less than causing the problem such as foaming.Along with the diversified demand of people to the cakingagent color, some enterprise has produced coloured cakingagent, but used pigment can stay permanent color in the bonded part, and the color that stays can have influence on the effect of bonded thing such as the color of wallpaper own.The cakingagent of patent CN101139506A report, the developer that uses is tropeolin-D, methyl violet, Congo red, dibromothymolsulfonphthalein, they can not fade after smearing fully, can leave a trace.
Patent CN101831259A reports a kind of coloured cakingagent that fades, and it uses polyvinyl alcohol, and cost is higher, also uses glutaraldehyde, not only so that the color of binding agent itself is unstable, and also unfriendly to environment.
Summary of the invention
The object of the invention is to provide a kind of coloured cakingagent and preparation method thereof that fades, and this coloured cakingagent cost is lower, environmentally friendly, the colour stable of binding agent, and can fade fully after smearing, bond effect is good.
A kind of coloured cakingagent that fades provided by the invention, its component is counted by weight:

Described starch can replace with sticky rice flour.
The preparation method of a kind of coloured cakingagent that fades provided by the invention comprises the steps:
1) takes by weighing according to the above ratio each raw material;
2) with anhydrous alcohol solution triarylmethane compound leuco compound dyestuff; Water preparation mass concentration is 5% sodium hydroxide solution;
3) heat water to 20～30 ℃, slowly add Xylo-Mucine and constantly stirring, after all dissolving, continue to be warming up to 80～90 ℃, add starch, constantly stir, add sodium alginate and polyacrylamide behind the starch dissolution, stir, be cooled to room temperature, add the ethanolic soln of triarylmethane compound leuco compound dyestuff, then add sodium hydroxide solution, after stirring, add sanitas and essence and namely make coloured cakingagent, sealing.
Compared with prior art, advantage of the present invention:
1) cakingagent of the present invention is smeared and can be faded fully in 5～10 minutes, does not stay any vestige.
2) cakingagent of the present invention uses starch as main component, and cost is low, is easy to a large amount of productions.
3) in cakingagent, add the viscosity that polyacrylamide can increase cakingagent.
4) do not use aldehyde material, make the cakingagent intrinsic colour stable, and environmental protection, harmless.
