Embodiment 1

[0015] A polyepichlorohydrin-dimethylamine organic polymer flocculant, its appearance is light yellow or colorless liquid, the cationic degree is 5-6mmol / g, the solid content is 60%-70%, and the viscosity is 2800-3200mpa ·s.

[0016] The preparation technology of above-mentioned polyepichlorohydrin-dimethylamine organic polymer flocculant is:

[0017] (1) Take 89-91 g of dimethylamine solution with a mass percentage concentration of 33%, place it in a 150ml three-necked round-bottomed flask, and place the flask in an ice-water bath to cool down the dimethylamine solution to below 10°C;

[0018] (2) Add 73-75g of epichlorohydrin into the separatory funnel, turn on the cooling water of the reflux condenser, and add the epichlorohydrin dropwise to the cold dimethylamine solution for 1-2 hours while stirring , so that the temperature in the reactor is controlled at 10°C to 20°C;

[0019] (3) After the dropwise addition is completed, stir for another 30 minutes to make the temper...

Abstract

An organic high-molecular flocculant with high flocculating effect for decoloring the printing and dyeing sewage in textile industry is prepared from epoxy chloropropane, dimethylamine and 1,6-hexyldiamine as cross-linking agent. Its preparing process is also disclosed.

Description

(1) Technical field [0001] The invention relates to a polyepichlorohydrin-dimethylamine organic polymer flocculant and a preparation process thereof, belonging to the field of chemical technology. (2) Background technology [0002] With the rapid development of our country's economy, the shortage of water resources will be one of the most prominent problems that our country will face in the future. The shortage of water resources will directly restrict the sustainable development of our country's social economy and the continuous improvement of human living standards. The shortage of water resources is caused by the lack of water in our country on the one hand, and the water pollution caused by the arbitrary discharge of a large amount of waste (sewage) water without effective treatment. Therefore, it is of great significance to strengthen the prevention and control of water pollution and improve the recycling rate of water. my country discharges a large amount of industri...
