Abstract

The invention discloses a preparation method for environment-friendly sticky rice glue. The preparation method comprises the following steps: (1) weighing raw materials; (2) cleaning sticky rice, soaking the sticky rice with deionized water, and adding into an acetic acid solution to soak; (3) preparing modified starch; (4) uniformly mixing the product obtained in step (2) with modified starch obtained in step (3), and adding urea and an emulsifying stabilizer to uniformly stir; (5) adding sodium tripolyphosphate, sodium stearate and anhydrous aluminum sulfate into a product obtained in step (4), stirring and uniformly mixing, and heating up to perform high-temperature pasting reaction; and (6) sequentially adding a bactericide, modified bamboo charcoal powder and a plant extracting solution into a pasting reaction product obtained in step (5), stirring and uniformly mixing, reacting and processing, cooling, sterilizing and packaging to obtain the environment-friendly sticky rice glue.The environment-friendly sticky rice glue takes sticky rice, starch and the like as raw materials, is less in additive, is high in viscosity, is long in storage time, and is excellent in freezing resistance.

Description

technical field [0001] The technical field of building materials of the present invention particularly relates to a preparation method of environmentally friendly glutinous rice glue. Background technique [0002] Glutinous rice glue, also known as glutinous rice glue, is an environmentally friendly adhesive made of pure natural glutinous rice or glutinous rice as raw material, after twelve processes such as glutinous rice purification, grinding, and drying. It has a wide range of applications and long viscosity. [0003] However, the traditional glutinous rice glue generally has problems such as low viscosity, poor anti-aging, thickening and hardening during storage, poor appearance, poor frost resistance resulting in decreased viscosity, high cost and laborious glue adjustment during construction. Contents of the invention [0004] The present invention provides a method for preparing environmentally friendly glutinous rice glue, which solves the problems in the backgrou...
