Embodiment Construction
[0010] 1. Pre-add 36.4m in the reactor 3 of water and 2.63m 3 Sodium silicate, after mixing, the temperature is controlled between 38°C and 42°C, and sulfuric acid with a concentration of 98% is added to make the pH value between 6.5 and 7;
[0011] 2. Dilute sodium silicate according to 17.5m 3 The flow rate of / h is added to the reactor, and the temperature is heated at the same time. When the temperature rises to 94 ° C ~ 96 ° C, and the pH value reaches between 11 ~ 12, keep the temperature and pH value at this time, and the reaction is 75 ~ 80 minute;
[0012] 3. Then the sulfuric acid with a concentration of 98% is 3 The flow rate of / h is added to the reactor, so that the pH value reaches between 4.5 and 4.6, and the reaction takes 28 to 32 minutes;
[0013] 4. Stop keeping the temperature, and obtain the product after aging for 20 minutes.

The invention relates to a preparation technique an environment-friendly thickener for toothpaste. Water, sodium silicate and concentrated sulfuric acid are organically combined and react to produce the thickener for toothpaste. The thickener for toothpaste has the advantages of stable indexes and low energy consumption in the production process, saves abundant cost, and can easily implement industrialized popularization.
Description
technical field [0001] The invention belongs to the technical field of chemical production, and in particular relates to a preparation process of toothpaste additives, in particular to a preparation process of an environmentally friendly thickener for toothpaste. Background technique [0002] Thickeners are also called gelling agents. Thickeners are needed in the toothpaste production field. In the traditional production process of toothpaste thickeners, the thickeners produced are often unstable, and the product consumes a lot of energy and has poor results. , leading to high production costs. Contents of the invention [0003] In view of the above problems, the present invention provides a preparation process of an environmentally friendly thickener for toothpaste. The toothpaste thickener produced by the process of the environmentally friendly thickener for toothpaste has stable indicators, low energy consumption in the production process, and saves a lot of cost. , ea...
