Embodiment Construction

[0021] The present invention is a method for preparing nano-zinc peroxide and zinc oxide by utilizing solar photochemical reaction mode. In the preparation method, hydrogen peroxide and zinc acetate are used as raw materials, hydrogen peroxide is added into deionized water first, and the mixture is evenly stirred. Under the condition of sunlight, dissolve zinc acetate in the above solution to obtain a solution with a concentration between 0.1mol / L-0.5mol / L, and obtain a white color after reacting at room temperature (0℃-40℃) for 8h-20h Sol, drying the sol at a temperature lower than 120° C. to obtain light yellow nano-powders of different sizes, which is zinc peroxide powder. If the powder is annealed at a high temperature of 400℃-800℃, white zinc oxide powder can be obtained.

[0022] The above-mentioned reaction may be carried out in a batch or continuous state.

[0023] In the process of the preparation method, dilute hydrochloric acid, dilute sulfuric acid, dilute nitric...

Abstract

The present invention provides a method preparing zinc peroxide and zinc oxide using solar energy. The zinc acetate and hydrogen peroxide are chosen to be material. The zinc acetate is dissolved in a mixture of hydrogen peroxide and deionized water. A white sol is obtained by reaction under sunlight illumination. The white sol is dried and a buff powder which is zinc peroxide powder is obtained. Then the powder is annealed in high temperature and a white zinc oxide powder is obtained. Through controlling pH value of the sol and reaction time, nanometer grain of zinc peroxide and zinc oxide which are provided with grain-controlled, good dispersivity, high purity and high crystallinity are obtained. Preparation method of the present invention is simple in process, easy in operating, mild in reaction condition and can be completed at room temperature, which has the advantages of energy-saving and environmental friendly.

Description

technical field [0001] The invention relates to a method for preparing nano-zinc peroxide and zinc oxide by utilizing solar photochemical reaction mode. Background technique [0002] Zinc peroxide is light yellow or white powder, insoluble in water. Zinc peroxide can be used in combination with bisamidated carbon as a blowing agent for the manufacture of high melting point synthetic resin foamed thermoplastic products. In the vulcanization of polysulfide rubber, zinc peroxide is used as a vulcanizing agent to produce oil-resistant and anti-aging sealants, pipes, etc., and is used in the vulcanization of carbonyl nitrile rubber to produce anti-wear rubber. In carboxynitrile butadiene rubber butadiene rubber, zinc peroxide is used as a hardener to enhance the scorch resistance and storage stability of unhardened rubber. Zinc peroxide can also be used as an oxidant and oxygen supply agent for explosives (such as explosives, pyrotechnics). During the production of ceramic ins...
