Preparation method for glutinous-rice adhesive with insusceptibility to wrinkling and good adhesion for paper lantern

Abstract

The invention discloses a preparation method for a glutinous-rice adhesive with insusceptibility to wrinkling and good adhesion for a paper lantern. The preparation method comprises the following steps: uniform mixing glutinous rice flour, starch sodium octenylsuccinate and water under stirring, adding Tween 60 and urea, and carrying out heating under stirring so as to obtain a first prefabricatedmaterial; uniformly mixing lignin fiber, diatomite and acetone, adding epoxidized soybean oil, carrying out uniform mixing under stirring, adding coco-hydroxyethyl sodium sulfate, water and maltitol,and carrying out heating under stirring so as to obtain a second prefabricated material; and adding the second prefabricated material, an epoxy resin adhesive, an antifoaming agent, glycol and a bactericide into the first prefabricated material, and carrying out uniform mixing so as to obtain the glutinous-rice adhesive with insusceptibility to wrinkling and good adhesion for the paper lantern. The glutinous-rice adhesive prepared by using the preparation method provided by the invention has high adhesion force; paper adhered by the glutinous-rice adhesive is not liable to generate the phenomenon of wrinkling after curing; meanwhile, the glutinous-rice adhesive has good toughness and high tensile strength, can effectively avoid artistic appearance of paper from decreasing due to high hardness after curing, has good wetting effect at the same time, and effectively prevents the phenomenon of crusting from occurrence.

Description

Technical field [0001] The invention relates to the technical field of paper lanterns, in particular to a method for preparing glutinous rice glue for paper lanterns that is not easy to wrinkle and adhere well. Background technique [0002] Paper lanterns are a common traditional folk handicraft. Lanterns made of paper are generally used for viewing or decoration to increase the festive atmosphere. At present, the decorative effect of paper lanterns is better than its lighting effect; It can be seen from the name that the main raw material for production is paper. Generally, glue is used to bond the paper shape on the lantern skeleton. The current glue for paper lanterns generally uses starch slurry for adhesion. Not only the bonding strength is low, but the glue is easy to cure. Cause the paper appearance to wrinkle, which seriously affects the decorative effect of the lantern. Summary of the invention [0003] Based on the technical problems existing in the background technolog...

[0002] Paper lanterns are a common traditional folk handicraft. Lanterns made of paper are generally used for viewing or decoration to add a festive atmosphere. At present, the decorative effect of paper lanterns is better than its lighting effect; It can be seen from the name that the main raw material for making is paper. Generally, glue is used to bond the paper shape on the lantern frame. The current glue for paper lanterns is generally adhered with starch slurry. Not only the bonding strength is low, but also the glue is easy to Causes the appearance of the paper to wrinkle, seriously affecting the decorative effect of the lantern
