Embodiment 1

[0020] In the concrete implementation of the present invention, a kind of preparation method of self-cleaning agent for kitchen is, at first according to mass percentage: take by weighing particle diameter and be that 1nm, mass fraction are 99% of water-based nano-visible photocatalyst liquid of 10%, stir at 5000rpm Next, according to the ratio of 0.1% by mass percentage, add silica sol film-forming agent, add 0.9% by mass percentage of deionized water, and stir at a high speed of 5000rpm for 30min to obtain the spray precursor solution; then according to the filling volume of 80% of the spray precursor liquid is added to the spray tank, and finally the one-step pressure canning method is used to fill 20% of the dimethyl ether propellant and seal it, that is, a new type of kitchen self-cleaning agent that can be directly sprayed.

Embodiment 2

[0022] In the concrete implementation of the present invention, a kind of preparation method of self-cleaning agent for kitchen is, at first according to mass percentage: take by weighing particle diameter and be that 150nm, mass fraction are 98% of water-based nano-visible photocatalyst liquid of 40%, stir at 3000rpm Next, add alumina sol film-forming agent according to the proportion of 2% by mass percentage, and stir at a high speed of 3000rpm for 120min to obtain the spray precursor solution; then add the spray precursor solution to the spray tank according to the proportion of filling volume of 10%, and finally The one-step pressure canning method is filled with 90% of the propane butane propellant and then sealed to obtain a new type of kitchen self-cleaning agent that can be directly sprayed.

Embodiment 3

[0024] In the concrete implementation of the present invention, a kind of preparation method of self-cleaning agent for kitchen is, at first according to mass percentage: take by weighing particle diameter and be 35nm, mass fraction be 98% of water-based nano-visible photocatalyst liquid of 25%, stir at 4000rpm Next, add alumina sol film-forming agent according to the ratio of 1.5% by mass percentage, add deionized water with 0.5% by mass percentage, and stir at a high speed of 4000rpm for 60min to obtain the spray precursor solution; then according to the filling volume of 30 % ratio of the spray precursor solution into the spray tank, and finally use a one-step pressure canning method to fill 70% of the trichlorofluoromethane propellant and seal it to obtain a new type of kitchen self-cleaning agent that can be directly sprayed.

Abstract

The invention relates to a preparation method of a self-cleaning agent for kitchens; the self-cleaning agent can effectively solve the problems of dispersion and suspension stabilization of photocatalytic purification self-cleaning agents and has good usability. After the self-cleaning agent is sprayed by a user directly, a purification film layer with good self-cleaning performance is formed, andthus the problems of long-term and effective pollutant-degrading and self-cleaning effects are achieved. The method comprises the steps: according to the mass percentage, firstly, adding 0.05-2% of afilm-forming agent into 98-99% of a water-borne nano-visible light catalyst liquid at the rotational speed of 3000-5000 rpm, mixing evenly, supplementing an insufficient part with deionized water, continuing to stir for 30-120 min at the rotational speed of 3000-5000 rpm, and thus obtaining a spray precursor liquid; and according to the weight, firstly, loading 10-80% of the spray precursor liquid into an atomizing can, then filling with 20-90% of a propellant by a one-step pressure canning method, sealing, and thus obtaining the finished product. The raw materials are rich, the preparation method is simple, the self-cleaning agent is easy to produce and prepare and low in cost, has good visible light catalytic performance, can effectively play pollutant-degrading and self-cleaning effects for a long time, and is an innovation in cleaning agents for kitchens.

Description

technical field [0001] The invention relates to a cleaning product, in particular to a preparation method of a kitchen self-cleaning agent. Background technique [0002] Photocatalytic environmental purification materials can be widely used in sewage treatment, air purification, antibacterial deodorization, anti-fog self-cleaning and other fields because they can convert light energy into chemical energy. However, because traditional photocatalytic materials can only respond to ultraviolet rays, their application in kitchens and other indoor places lacking ultraviolet rays is greatly limited. Visible photocatalytic materials can efficiently utilize indoor natural light to undergo electronic transitions. The electrons and holes generated by the transitions react with the oxygen and water in the air adsorbed on the surface of nanomaterials to generate a large number of hydroxyl radicals and superoxide radicals. This group has strong chemical reactivity, and can oxidize and de...
