preparation example Construction

[0020] Embodiments of the present invention also provide a method for preparing a nanoscale deodorant, the method comprising the following steps:

[0021] The first step: mixing 20-40 parts of diatomite, 5-20 parts of inorganic basic compound, 5-25 parts of aluminum oxide, 1-6 parts of polyvinyl alcohol and 30-50 parts of water. Specifically, each component is added into the reaction kettle according to certain parts by weight for mixing. Wherein, the selection of each component can refer to the above-mentioned embodiments, and will not be repeated here. Preferably, the parts by weight of each component in the mixture can be as follows: 25-50 parts of diatomite, 10-15 parts of inorganic basic compound, 10-20 parts of aluminum oxide, 2-5 parts of polyvinyl alcohol and water 35-45 servings. Further preferably, the parts by weight of each component in the mixture can be as follows: 30 parts of diatomaceous earth, 12 parts of inorganic basic compound, 15 parts of aluminum oxide,...

Embodiment 1

[0028] Put 40kg of diatomaceous earth, 20kg of sodium hydroxide, 20kg of aluminum oxide, 5kg of polyvinyl alcohol and 60kg of water into the reactor and mix them; heat the mixture to 60°C and turn it at 500-1000 rpm Obtain army green gelatinous solid after 1 hour stirring in the mixer of / minute, general green gelatinous solid is air-dried 1 hour at room temperature; Sieve on a 1mm sieve plate (the length, width and height of the sieve hole are 1mm), then put the sieve plate together with the granular matter into a vacuum freezer and freeze-dry for 4h to obtain the granular matter; finally the granule The granular substance is placed in a heating drum at 200°C and heated until the granular substance turns into a white spherical solid, that is, a nano-scale deodorant.

[0029] See Table 1 for the raw material compositions and parts by weight of Examples 2 to 5.

Abstract

The invention provides a nano-level smell removal agent and a preparation method thereof. The smell removal agent comprises the following components in parts by weight: 20-55 parts of diatomite, 5-20 parts of an inorganic alkaline compound, 5-25 parts of alumina, 1-7 parts of polyvinyl alcohol, and 30-60 parts of water. The smell removal agent has a porous structure of diatomite, alumina and polyvinyl alcohol are uniformly distributed on the surface of diatomite, diatomite has dual functions of physical adsorption and chemical adsorption, and can absorb and remove stink smell in air in rooms, vehicles, refrigerators, shoe cabinets, toilets and dustbins; the inorganic alkaline compound is distributed on the surface of the diatomite, the acid-base property of the diatomite can be adjusted, so that the smell removal agent is environment friendly. The smell removal agent can absorb and discharge moisture freely, has effect for damping the environment, and solves the problem of single function of the smell removal agent.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a nanoscale deodorant and a preparation method thereof. Background technique [0002] Newly renovated houses, new cabinets, wardrobes and shoe cabinets will produce formaldehyde, benzene series (toluene, xylene, etc.), radioactive elements and total volatile organic compounds, etc., accompanied by certain irritating gases. Food, human secretions and their decomposition products in the refrigerator will cause odor. The main components of odor are fatty acid compounds, nitrogen compounds, mercaptans and hydrogen sulfide. health is also harmful. [0003] At present, deodorizing products on the market are mainly made of inorganic porous substances such as activated carbon, bamboo charcoal, and nano-mineral crystals, and are packaged in breathable non-woven fabrics. And other problems such as slow adsorption speed, resulting in poor deodorization effect. Contents of the i...
