Background
The adhesive is closely related to our life and is applied to the aspects of life, such as furniture, tables and chairs, floors, wall cloths, batch ash and the like. The quality of the adhesive on the market is uneven, and each kilogram varies from several yuan to tens of yuan; and people buy some relatively inexpensive products in pursuit of economy. In order to reduce the cost, the adhesive manufacturer generally adds starch and calcium powder into the product to reduce the cost, thereby achieving the use effect of the product; however, the starch-added product is easy to deteriorate, which is unfavorable for long-term storage of the adhesive.
In order to solve the above problems, some manufacturers add formaldehyde to the starch-containing adhesive product to extend the shelf life of the product. Although formaldehyde is added to effectively prevent the deterioration of the product, formaldehyde is a toxic substance which is easy to cause cancer.
In view of the foregoing, there is a need to provide an environmentally friendly and antiseptic method that reduces costs and allows long-term storage of starch adhesives.

(3) Cooling the adhesive to below 50 ℃ in a cooling kettle, adding a second preservative containing a CMIT, MIT and Bronopol composite system accounting for 1-3 per mill of the total kettle adhesive by mass, and uniformly stirring.
Further, the first antiseptic bactericide is double-chain quaternary ammonium salt antiseptic bactericide.

further, the second preservative containing the CMIT, MIT and Bronopol composite system is specifically: the mass fraction of CMIT is 2.2%, the mass fraction of MIT is 0.3%, and the mass fraction of Bronopol is 6%.
And (3) in the step (1), the ionized water and the starch are automatically conveyed and metered through a pipeline, and the starch slurry is automatically conveyed into a polymerization reaction kettle through the pipeline after being completely dissolved.
Further, the polymerization, starch gelatinization, and cooling are carried out in stages based on pipe-line transportation.
Further, the high-temperature gelatinization in the step (2) is specifically: gelatinizing at 76-80deg.C for more than 30 min.
