Embodiment 1

[0019] A preparation method of deodorant, comprising the following steps:

[0020] Step 1: Soak montmorillonite and diatomite in 0.5% hydrochloric acid solution for 40 minutes, filter and wash with water until the pH value of the washing solution is greater than 6.5, then dry the obtained montmorillonite and diatomite respectively ; Mix the soaking liquid and the washing liquid to obtain a mixed liquid, mix according to the ratio of the mixed liquid: sulfuric acid solution mass ratio of 20:1, the concentration of the sulfuric acid solution is 0.5%, heat and concentrate the obtained concentrated solution to cool to 25 ° C for crystallization Separation obtains crystals and separation liquid, and the crystals are sold as by-products;

[0021] Step 2, the montmorillonite obtained by step 1: the diatomite obtained in step 1: calcium carbonate: industrial sodium chloride: the mass ratio of platinum nitrate is mixed in the ratio of 2:1:0.5:0.05:0.05, and then put into Rotary kiln c...

Embodiment 2

[0026] Example 2 is the same as Example 1, except that after step 1, step 2 and step 3 are completed, the powder obtained in step 3: the mass ratio of compound additives is 50:50 and added to the mixing and stirring furnace for heating and mixing. The heating temperature is 100°C, the mixing time is 2 hours, and the finished product is obtained after cooling, and the compound additive is rosin.

[0027] In the preparation process of nitrile rubber products, 0.8% of the deodorant prepared in Example 2 was added. After testing, its absorption rate of benzene was 84%, the removal rate of formaldehyde was 84%, and the removal rate of ammonia nitrogen compounds was 87%. %, the removal rate of TVOC (volatile organic compounds) was 82%.

Embodiment 3

[0029] A preparation method of deodorant, comprising the following steps:

[0030] Step 1: Soak montmorillonite and diatomite in 0.8% hydrochloric acid solution for 35 minutes respectively, filter and wash with water until the pH value of the washing liquid is greater than 6.5, then dry the obtained montmorillonite and diatomite respectively The soaking liquid and the washing liquid are mixed to obtain a mixed solution, and the mass ratio of the mixed solution: a sulfuric acid solution is mixed in a ratio of 20:1, and the concentration of the sulfuric acid solution is 0.5%, and after heating and concentrating, the concentrated solution of the gained is cooled to 30 DEG C for crystallization Separation obtains crystals and separation liquid, and the crystals are sold as by-products;

[0031]Step 2, the montmorillonite obtained by step 1: the diatomite obtained in step 1: calcium carbonate: industrial sodium chloride: the mass ratio of aluminum salt is mixed in the ratio of 3:1....

Abstract

The invention relates to the technical field of filling material, and discloses a preparation method of a deodorant. The preparation method comprises the following steps of (1) respectively soaking silicate mineral powder and diatomite into a hydrochloric acid solution, and respectively drying; (2) mixing the silicate mineral powder and diatomite obtained in step (1) and calcium carbonate, industrial sodium chloride and metal salt according to a ratio, putting into a rotary kiln, and calcining, so as to obtain a metal oxide and silicate mixture; (3) cooling the mixture obtained in step (2), finely grinding by a roll press grinder, screening, soaking the screened mixture, drying the soaked mixture in a dryer, finely grinding and screening, so as to obtain a product. The preparation method has the advantages that the waste water and waste slag are fully utilized in the preparation process, so that the safe, green and environment-friendly effects in the whole production process are realized; the deodorizing effect of the product is excellent, the usage amount is less in comparison with the usage amount of similar products, and the cost is reduced; the application field of products is wide, and the product can be applied to the fields of rubber, plastic, paint, sewage treatment and the like.

Description

technical field [0001] The invention relates to the technical field of filling materials, in particular to a preparation method of a deodorant. Background technique [0002] With the development of society, the demand for rubber and plastic will increase. Rubber and plastic products are mainly used in industries, daily necessities, medical care, automobiles and other fields. During the processing or use of rubber and plastic products, harmful substances such as acids, alkoxy compounds, aldehydes, vinyl compounds, ammonia, and CO2 will be produced. These substances have a pungent odor and are extremely harmful to humans if inhaled for a long time Large, easy to cause respiratory and skin lesions and even cancer, in addition to secondary pollution to the environment, so researchers have developed rubber and plastic deodorants, the current rubber and plastic deodorants are mainly activated carbon, zeolite molecular sieve, calcium chloride and organic ester amine compounds, but...
