Abstract

The invention relates to composite tea saponin, a preparation method thereof and use thereof. The composite tea saponin is prepared by mixing a proper a mount of water with raw materials including 1 to 3 percent of nano titanium oxide, 12 to 18 percent of tea saponin, 1 to 5 percent of methylcellulose, 23 to 45 percent of natural soap powder, 3 to 5 percent of infusorial earth, 6 to 12 percent of sepiolite and 5 to 10 percent of sodium carbonate. The preparation method mainly comprises: nano titanium oxide dispersion, dust-free compounding, granulation and synthesis, wherein the finished product is homogenized by a sieve and discharged in form of grains. The tea saponin can replace one or both of caustic soda and hydrogen peroxide as a finishing agent for use in the fields of textile, leather, paper making, sewage treatment and daily chemical industry. The preparation method can meet the original technical requirements of production and processing industries on the use of the caustic soda and the hydrogen peroxide, simplify technical process, avoid equipment corrosion and material damage, improve product quality, discharge waste water in an environmentally-friendly manner, ensure safety of human bodies, reduce production cost, save energy, labor and time and realize ecological, environmentally-friendly and safe production.

Description

technical field [0001] The invention relates to chemical products in the field of environmental protection, and relates to a substitute for caustic soda (sodium hydroxide) and hydrogen peroxide (hydrogen peroxide), in particular to a compound tea saponin and its preparation method and application. Background technique [0002] Everyone in the industry knows that caustic soda, chemical name: sodium hydroxide, molecular formula: NaOH, is a hazardous chemical. It is a white crystal at normal temperature, which is a strong alkali and highly corrosive, and its aqueous solution is strongly alkaline. Vigorous reaction can occur in contact with water, releasing a large amount of heat, which can corrode metal, rubber, plastic, fabric, etc. During storage, transportation and use, it is very easy to cause environmental pollution, economic loss, personal injury and production accidents. [0003] Hydrogen peroxide, chemical name: hydrogen peroxide, molecular formula: H 2 o 2 , has st...
