Embodiment 1

[0024] Inject 3000 kilograms into the reactor, then slowly add 1000 kilograms of itaconic acid mycelium into the reactor, and stir at a low speed until uniform, then add 10 kilograms of 30% hydrogen peroxide, and carry out fully under the condition of 65°C-70°C Oxidation to obtain the oxidized solution, then stir the oxidized solution at a high speed under the condition of 65°C-70°C, and add 30 kg of sodium hydroxide to make the oxidized solution undergo liquid gelatinization, and then pour into the liquid gelatinized solution Add 10 kilograms of borax in the medium, and after continuing high-speed stirring ten minutes, adjust its viscosity, obtain 5000 kilograms of binders. The utilization rate of the itaconic acid mycelium is over 90%, which realizes the recycling of resources, improves the utilization rate of the itaconic acid mycelium, and reduces the cost of making the adhesive. Among them, low-speed stirring means that the rotating speed of the stirring blade is between ...

Embodiment 2

[0026] Inject 6,000 kg into the reactor, then slowly add 2,000 kg of itaconic acid mycelia into the reactor, stir evenly at a low speed, then add 20 kg of 30% hydrogen peroxide, and fully oxidize at 65°C-70°C , to obtain the oxidized solution, and then stir the oxidized solution at a high speed under the condition of 65°C-70°C, and add 60 kg of sodium hydroxide to make the oxidized solution undergo liquid gelatinization, and then pour it into the liquid gelatinized solution Add 20 kilograms of borax, and after continuing to stir at high speed for ten minutes, adjust its viscosity to obtain 11000 kilograms of adhesive. The utilization rate of the itaconic acid mycelium is above 90%, which realizes the recycling of resources, avoids the consumption of a large amount of food, turns waste into wealth, and reduces pollution sources. Among them, low-speed stirring means that the rotating speed of the stirring blade is between 500 rpm-800 rpm, high-speed stirring means that the rotat...

Abstract

The invention discloses a method for manufacturing an adhesive by using itaconic acid mycelia, which comprises: slowly adding itaconic acid mycelia into water according to a weight ratio with constant stirring, and adding an oxidant at a certain temperature to perform a full oxidation reaction to obtain mixed solution; and stirring the mixed solution at a high speed, adding a certain amount of alkaline compound, reacting till the solution is pasted, adding a stabilizer, fully reacting, and adjusting the viscosity to obtain the adhesive. In the invention, the adhesive is obtained by fully mixing the itaconic acid mycelia with water, treating by the oxidant, sodium hydroxide and sodium borate in turn and regulating the viscosity, the reuse of the itaconic acid mycelia is realized, the utilization rate of the itaconic acid mycelia is improved, waste materials are changed into useful materials, pollutant sources are reduced, large grain consumption is avoided and the manufacturing cost ofthe adhesive is reduced.

Description

technical field [0001] The invention relates to a method for producing an adhesive, in particular to a method for making an adhesive by using itaconic acid mycelia. Background technique [0002] The adhesive used in the production of packaging boxes in the prior art is mainly prepared from corn starch, which not only consumes a large amount of food (200 kg of corn starch per ton of adhesive), but also has a high cost (about 400 yuan per ton). Itaconic acid is a dibasic unsaturated organic acid with a wide range of uses, which is rarely found in nature, and is now mostly prepared by fermentation. During the production process, a large amount of itaconic acid waste residues such as itaconic acid protein residue and itaconic acid mycelium are produced. These substances are highly polluting and cannot be discarded directly, otherwise they will cause serious pollution. At present, there is no report on the method of using itaconic acid mycelia to make adhesives. Contents of th...
