Problems solved by technology

Since most of them are recycled bottles, the cleaning process is very important, and incomplete cleaning will directly affect product quality and food safety
At present, liquid caustic soda is mostly used as bottle washing agent in China. Although it can meet the basic cleaning requirements, caustic soda has a certain corrosive effect on recycled bottles. In addition, it will cause blurred and opaque bottles after cleaning, and the cleaning waste liquid will endanger the environment.
In recent years, although related compound bottle washing agents have come out, they have the following problems: the old bottle label paper cannot be completely peeled off; the washing effect is poor, and the old label glue on the bottle body is obvious after washing; the bottle body is not bright after washing; advanced questions

Embodiment 1

[0025] Prepare high-efficiency low-foam bottle washing agent, the specific steps are as follows:

[0026] (1) Take 0.6mol of epichlorohydrin in a 250mL three-neck flask equipped with a rotor and a reflux condenser, heat it to 40°C, slowly add 0.02mol of triethylamine under the condition of 300r / min and stir for 20min, then put The three-necked flask was placed in a microwave reactor, and reacted for 2 hours at a microwave power of 600w and a stirring rate of 150r / min. After the reaction, the product was decompressed and rotary evaporated to remove the solvent, and dried in vacuum to obtain product A;

[0027] (2) Measure 20mL of triacontanol into a 250mL three-neck flask equipped with a rotor and a reflux condenser, heat to 60°C, slowly add 200mL of product A at 300r / min, stir for 20min, then add 15mL of chitosan Sugar acid solution (chitosan is dissolved in 5wt% acetic acid solution to obtain, wherein the mass fraction of chitosan is 1%), then the three-necked flask is put in...

Embodiment 2

[0032] Prepare high-efficiency low-foam bottle washing agent, the specific steps are as follows:

[0033] (1) Take 1mol of epichlorohydrin in a 250mL three-necked flask equipped with a rotor and a reflux condenser, heat it to 50°C, slowly add 0.02mol of triethanolamine under the condition of 300r / min and stir for 20min, then put the three-necked flask Put it into a microwave reactor and react for 2 hours at a microwave power of 650w and a stirring rate of 200r / min.

Abstract

The invention relates to an efficient low-foam bottle washing agent and a preparation method thereof. The preparation method comprises: 1) carrying out a reaction on epichlorohydrin and an organic alkali under microwave irradiation to obtain a product A; 2) uniformly mixing triacontanol and the product A, adding a chitosan acid solution, and carrying out a reaction under microwave irradiation to obtain a surfactant B; 3) grinding zinc acetate, NaF and citric acid to obtain an auxiliary agent C; 4) dissolving the surfactant B and the auxiliary agent C in water, and adjusting the pH value to 8 to obtain a semi-finished product D; and 5) mixing ethylene glycol, EDTA and the semi-finished product D according to a mass ratio of 5-10:0.5:100, and stirring uniformly to obtain the efficient low-foam bottle washing agent. According to the present invention, with the efficient low-foam bottle washing agent, the whole label paper can shed off without glue residue; and the efficient low-foam bottle washing agent is weakly alkaline, does not damage the bottle body, and has characteristics of low foam and easy rinsing, wherein the bottle body is bright after being washed, and the residual liquidis neutral.

Description

technical field [0001] The invention belongs to the technical field of detergents, and relates to a high-efficiency and low-foaming bottle washing agent and a preparation method thereof. Background technique [0002] At present, beverages and beer produced in my country are mainly bottled. Most of the bottles are recycled from old bottles, cleaned and reused. Since most of them are recycled bottles, the cleaning process is very important, and incomplete cleaning will directly affect product quality and food safety. At present, liquid caustic soda is mostly used as bottle washing agent in China. Although it can meet the basic cleaning requirements, caustic soda has a certain corrosive effect on recycled bottles. In addition, it will cause blurred and opaque bottles after cleaning, and the cleaning waste liquid will endanger the environment and other problems. In recent years, although related compound bottle washing agents have come out, they have the following problems: th...
