Abstract

The invention relates to a preparation method of a degumming agent, and belongs to the technical field of glue cleaning. The bio-enzyme and the citric acid-sodium citrate buffer solution are mixed, the inorganic solvent sodium peroxide, the organic solvent ethylene glycol carbonate, the auxiliary sodium tripolyphosphate and the surfactant are combined to prepare the environment-friendly degummingagent, the degumming efficiency is high, and degumming is thorough; the bio-enzyme is an organic matter which is generated by living cells and has a catalytic effect, most of the bio-enzyme is protein, a small part of the bio-enzyme is RNA, degumming by a bio-enzyme method is to catalyze and hydrolyze colloid by directly utilizing a bio-enzyme preparation or extracted degumming enzyme liquid, degumming is realized, the process is simple, and the operation is flexible; and the organic solvent in the degumming agent is used for dissolving and dispersing the glue, reducing the molecular weight and viscosity, dispersing the glue into microparticles and stripping the residual glue.

Description

technical field [0001] The invention relates to a preparation method of a degumming agent, belonging to the technical field of glue cleaning. Background technique [0002] Glue is a common tool in our daily work and life, which greatly facilitates our work and life. However, after we tear off the glued paper and other items, such as labels, there will always be traces of watering, which not only affects the appearance, but also is inconvenient to use. The invention utilizes the solubility of the main components in the glue to dissolve the residual glue, has a good cleaning effect on ordinary glue, is easy to use, and has very little harm to the human body and the environment. [0003] In the vast cities of our country, illegal small advertisements are very rampant, which seriously endangers the social atmosphere and defaces buildings and public facilities. It is difficult to use traditional methods to remove "urban psoriasis" effectively. Now imported French "sensitive mat...
