Abstract
The invention relates to a method for preparing a water soluble non-setting adhesive. The method comprises the following steps of: swelling the gelatin in normal-temperature water in a container, adding an additive, heating the mixture, stirring to allow the gelatin and the additive to dissolve in water completely, adding polyvinyl pyrrolidone, and continuing stirring till the polyvinyl pyrrolidone dissolves completely; and sealing the container at last, keeping the temperature in the container, dewatering the product in a vacuum dewatering device, cooling the product, discharging the product to be stored. The soluble non-setting adhesive is suitable to be used on paper trademarks or tags, has characteristics of common non-setting adhesive and can be torn off and adhere repeatedly. The non-setting adhesive can quickly and completely dissolve in water without leaving any traces on materials to be adhered.
Description
Technical field
The present invention relates to be adapted to the compound trade mark of papery or paper and label non-setting adhesive, be specifically related to a kind of preparation method of water-soluble non-setting adhesive.
Background technology
Growing along with commodity packaging, trade mark and label are more and more higher with consumption and the specification of quality of non-setting adhesive, modal non-setting adhesive generally is the emulsion of aqueous acrylic modified class, being coated on commodity or the label substrate then, drying forms, this non-setting adhesive has the initial bonding strength height and holds the good advantage of viscous force, so be widely used in commodity, label and non-setting adhesive sealing tape etc. always.But it is exactly the article that are stuck that this class non-setting adhesive has a fatal shortcoming, the utmost point is not easy to strip off after pasting for a long time, even also be not easy washing with washing composition and clean, so that the article that are stuck are easy to stay dirt, thereby affect the outward appearance of commodity and attractive in appearance.Also some more senior non-setting adhesive such as hot-melt non-setting adhesive, use properties is also very excellent, but also unusual costliness of price, so can only use in the packing of some top grades and high-end product.
Summary of the invention
The objective of the invention is to be to overcome existing trade mark or the used non-setting adhesive of label after use, be not easy to peel off and clean clean defective and develop a kind of have fully can be water-soluble non-setting adhesive.The non-setting adhesive that the present invention prepares not only has the characteristic of general non-setting adhesive, and can be fully water-soluble owing to it after using, and institute and easy cleaning are clean, and do not stay any stains to the adherend product.
The present invention is achieved by the following technical solutions:
A kind of preparation method of water-soluble non-setting adhesive, it comprises the following steps:
(1) gelatin is placed container water normal temperature swelling, then press formula metering and add softening agent, solubilizing agent, surface wettability agent and sanitas, and mixture is heated up, stir, make gelatin and add materials and in water, dissolve fully, add again Polyvinylpyrolidone (PVP), continue to stir, dissolve fully to Polyvinylpyrolidone (PVP); The parts by weight of each material are:
