Embodiment 1

[0031] Preparation of enzymatic hydrolyzate:

[0032] Put the bean dregs and soybean straw into the oven at a mass ratio of 3:1, dry for 3 hours at a temperature of 60°C, and put them into a planetary ball mill after drying. Grinding and mixing for 100 min to obtain a grinding product, the grinding product and a mass fraction of 10% sodium hydroxide solution are dropped into a beaker at a mass ratio of 1:5 and mixed uniformly to obtain a mixed slurry;

[0033] Put the above beaker in a water bath, raise the temperature of the water bath in the water bath to 95°C, mix and stir with a stirrer at a speed of 300r / min for 60min to prepare an alkaline reaction solution, and add the alkaline reaction solution to the beaker Silica powder with a mass of 6% was continuously mixed and stirred for 2 hours at a water bath temperature of 95° C. to prepare a modified emulsion;

[0034] Put the above-mentioned modified emulsion into a three-necked flask, add dropwise hydrochloric acid with a...

Abstract

The invention discloses a preparation method of a freeze-proof moisture-proof label adhesive, and belongs to the technical field of polymer adhesives. According to the method provided by the invention, soybean dregs and soybean stalks are subjected to lye high-temperature water boiling to extract plant organic fiber components, a soybean protein in the soybean dregs is hydrolyzed to generate a large number of amino and carboxyl free radicals, so that the bonding properties of the label adhesive are improved, and the label adhesive is prevented from easily falling; and corn starch and organic fibers are mixed, microbial corrosion fermentation treatment is performed by xanthomonas campestris to generate xanthan gum, the xanthan gum component is a polysaccharide component with high viscosity,the main chain of the molecular has a regular curly double-helix structure, so that the molecular structure is stable, good bonding properties can be maintained in the low-temperature environment, the viscosity of the label adhesive can be greatly increased, the bonding degree among the molecules in the label adhesive is improved, and the label adhesive uneasily falls off.

Description

technical field [0001] The invention discloses a method for preparing an antifreeze and moisture-proof label adhesive, which belongs to the technical field of polymer adhesives. Background technique [0002] Label glue, also known as trademark glue, refers to the adhesive used to paste labels. As early as 1700, Europe printed the first batch of labels used on medicines and cloth as product identification, so, strictly speaking: the label is used to mark the classification or content of your target, like the target you gave Defined keywords, tools for yourself and others to find and locate your goals. Most of the labels referred to in the printing industry are printed materials used to identify the relevant instructions of their own products, and most of them are self-adhesive on the back, but there are also some that are printed without adhesive, which can also be called labels. For example : Most of the beer labels are printed without glue, which is pasted by the manufact...
