Description
Technical field
The present invention relates to glutinous rice glue technical field, more particularly to a kind of glutinous rice glue preparation method of high adhesion.
Background technology
At present, wallpaper has been because of multiple advantages such as its material environment friendly, bright-colored, sound-insulation and heat-insulation and short construction periods
The main trend of wall surfacing at present.When pasting wallpaper, Glutinous rice wet glue is because it is environmentally friendly, cohesion is strong, lower-cost spy
Point, obtain more and more extensive use.Glutinous rice glue is mainly the agent based on each kind of starch, is aided with various auxiliary materials, by suitable
The highly viscous amylan of a kind of environment-friendly water-soluble made from temperature reaction in a kettle after proportioning.But current glutinous rice glue is viscous
Attached power is poor, and hardening phenomenon easily occurs in the extension after construction over time, causes wallpaper to warp, and influences indoor beauty, it would be highly desirable to solves
Certainly.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of glutinous rice glue preparation method of high adhesion,
Technique is simple, and production cost is low, and the feature of environmental protection is good, and gained glutinous rice glue long shelf-life, freeze-thaw stability is strong, and storage stability is high, applies
Hardening phenomenon is less prone to after work.
A kind of glutinous rice glue preparation method of high adhesion proposed by the present invention, comprises the following steps：
S1, glutinous rice flour, animal glue, etherification starch, water is well mixed, adds urea, potassium oleate continues to stir, heated up,
