Phosphoric-acid-base modified polycarboxylic-acid water reducer with high adaptability and preparation method thereof

The invention discloses a phosphoric-acid-base modified polycarboxylic-acid water reducer with high adaptability and a preparation method thereof. The water reducer is prepared from the following raw materials: isopentenol polyoxyethylene ether, hydrogen peroxide, acrylic acid, an unsaturated phosphoric acid monomer, deionized water, a reducing agent, and a chain transferring agent. The chain transferring agent is one of mercaptoethanol, mercaptoacetic acid and mercaptopropionic acid. The unsaturated phosphoric acid monomer is prepared from 2-phosphono-1,2,4-butanetricarboxylic acid, p-toluenesulfonic acid and hydroquinone. The preparation method for the water reducer comprises adding isopentenol polyoxyethylene ether and deionized water into a reaction vessel, uniformly stirring, heating, keeping warm, adding oxygen peroxide, then dropwise adding a material solution by employing a constant-flow pump, continuing to keep warm for reacting for 1-1.5 h after dropwise adding of the material solution is finished, naturally cooling to room temperature, and adjusting the pH value of the obtained product to 5-6 by using an alkaline solution. The phosphoric-acid-base modified polycarboxylic-acid water reducer possesses good sulfate ion resisting capability and sludge resisting capability, thereby satisfying engineering demand.

Screening method for hemostatic and antibacterial Chinese herbal medicine and toothpaste formula

The invention discloses a screening method for hemostatic and antibacterial Chinese herbal medicine and a toothpaste formula, and belongs to the technical field of Chinese herbal medicine toothpaste preparation. The screening method for the Chinese herbal medicine comprises the first step of establishing an assessment index system, the second step of determining assessment index weights and checking consistency, and the third step of conducting quantification processing through fuzzy comprehensive judgment and conducting screening to obtain hemostatic and antibacterial Chinese herbal medicine. The toothpaste formula comprises 1-3.2% of Chinese herbal medicine, 64.8-66.1% of auxiliaries, and the balance deionized water, wherein the sum of weight percents of Chinese herbal medicine, auxiliaries and deionized water is 100%. By means of the Chinese herbal medicine toothpaste, a protection film can be formed on the gingival, the gingival can be protected for a long time, and the resistance to sensibility of the gingival can be improved. Compared with ordinary chemical toothpaste, the Chinese herbal medicine toothpaste has the advantages that smell is good, and decayed teeth, gum bleeding and other oral cavity problems can be remarkably eased, relieved and prevented when used for a long time.
