Problems solved by technology

[0002] It is well known in the glue production industry that the traditional glue does not contain a drier, which makes the initial solidification speed of the product slow. Therefore, when this glue is used for bonding, it is easy to appear flute phenomenon, which makes the glue waste serious.
In addition, traditional glue needs to be heated during the production process.
Due to the need for heating, it consumes a lot of energy and the production cost is high

Embodiment 1

[0034] Prepare 400 parts of tap water, 90 parts of cornstarch, 1.5 parts of borax, 3.5 parts of concentrated sulfuric acid, 0.02 parts of tributyl phosphate, 0.12 parts of potassium permanganate, 1.5 parts of masking agent, and 8 parts of hydrogen Sodium oxide, 0.01 part of drier, and 0.1 part of sodium sulfite are for use; wherein, the concentration of the concentrated sulfuric acid is 85%, and the drier is an inorganic drier.

[0035] Afterwards, the cornstarch is oxidized

[0036] Put corn starch and 80% tap water together, stir well to make starch emulsion; while stirring, add concentrated sulfuric acid diluted to 30% and 3% potassium permanganate solution, stir well and place at room temperature 10 hours, carry out oxidation reaction, make starch emulsion become pure white starch emulsion;

[0037] Afterwards, rinse

[0038] Add the remaining tap water to the pure white starch emulsion, and stir for 8 minutes. After standing for an hour at room temperature, remove the u...

Embodiment 2

[0048] Prepare 500 parts of tap water, 100 parts of corn starch, 1.8 parts of borax, 4.0 parts of concentrated sulfuric acid, 0.04 parts of tributyl phosphate, 0.13 parts of potassium permanganate, 1.7 parts of masking agent, 9 parts of Sodium hydroxide, 0.02 part of drier, 0.13 part of sodium sulfite, set aside. Wherein, the concentration of the concentrated sulfuric acid is 85%, and the drier is an inorganic drier.

[0049] Afterwards, the cornstarch is oxidized

[0050] Put corn starch and 80% tap water together, stir well to make starch emulsion; while stirring, add concentrated sulfuric acid diluted to 30% and 3% potassium permanganate solution, stir well and place at room temperature 13 hours, carry out oxidation reaction, make starch emulsion become pure white starch emulsion;

[0051] Afterwards, rinse

[0052] Add the remaining tap water to the pure white starch emulsion, and stir for 9 minutes. After standing for an hour at room temperature, remove the upper layer...

Embodiment 3

[0062] Prepare 600 parts of tap water, 95 parts of corn starch, 2.0 parts of borax, 4.5 parts of concentrated sulfuric acid, 0.06 parts of tributyl phosphate, 0.15 parts of potassium permanganate, 2.0 parts of masking agent, 10 parts of Sodium hydroxide, 0.03 part of drier, 0.15 part of sodium sulfite, set aside. Wherein, the concentration of the concentrated sulfuric acid is 85%, and the drier is an inorganic drier.

[0063] Afterwards, the cornstarch is oxidized

Abstract

The invention discloses cold molding glue water and a preparation method thereof, and particularly cold molding glue water by a potassium permanganate oxidation method and a preparation method thereof. The cold molding glue water is prepared by oxidizing, rinsing, pasting, complexing, defoaming and drying by using raw materials of tap water, corn starch, borax, concentrated sulphuric acid, tributyl phosphate, potassium permanganate, masking agent, sodium hydroxide, drier and sodium sulfite, etc. By using the glue water for splicing, glue water can be saved to avoid waste. By adopting the method, the energy consumption is low, and the production cost can be lowered.

Description

technical field [0001] The invention relates to a glue and a production method thereof. Specifically, it is a potassium permanganate oxidation cold glue and a preparation method thereof. Background technique [0002] It is well known in the glue production industry that the traditional glue does not contain a drier, which makes the initial solidification speed of the product slow. Therefore, when this glue is used for bonding, it is easy to appear flute phenomenon, which makes the glue waste serious. In addition, traditional glue needs to be heated during the production process. Due to the need for heating, the energy consumption is high, and the production cost is relatively high. Contents of the invention [0003] The problem to be solved by the present invention is to provide a cold glue. Using this glue for bonding can save glue and avoid waste. [0004] Another problem to be solved by the present invention is to provide a method for preparing cold glue. By adopti...
