Problems solved by technology

[0003] In order to purify indoor air, there are various types of products in the market, such as coating type, mechanical filter type, and spray type. Among them, the brands of coating or spray type products are mixed, and the quality varies greatly. Even the products themselves contain harmful substances. Substances such as formaldehyde, VOC, etc., not only cause harm to the human body, but also cause serious pollution to the environment
Other types of products are also unable to meet people's needs for indoor air purification due to various shortcomings. Therefore, there is an urgent need for a surface treatment material that is truly environmentally safe and can purify indoor air for a long time on the market.

preparation example Construction

[0038] The present invention also provides a preparation method for the above-mentioned surface treatment material, comprising the following steps:

[0039] The nano precious metal particles are mixed with the latex paint in a mass ratio of (0.5-10%): (90-99.5%).

[0040] It can be understood that by adjusting the formulation of the nano-precious metal particles and the latex paint, it can be suitable for coating on various materials, such as buildings, vehicles, ships, plastics, rubber products, etc.

[0041] In some preferred embodiments, wherein, the nano-noble metal particles are prepared by the following method:

[0042] Mix the acidic aqueous solution of the noble metal with the docosyltrimethylammonium bromide solution to obtain a mixed solution; drop the mixed solution into an aqueous solution of sodium borohydride, then stir and let the mixed solution and deionized water Layering; extracting the mixed solution in the upper layer to obtain an aqueous solution containi...

Embodiment 1

[0048] 85ml of auric acid (HAuCl 4 ) aqueous solution mixed with 0.52 g of dodecyltrimethylammonium bromid (Didodecyl-dimethyl ammonium bromid) solution; then placed on a stirrer and stirred at a constant speed for 30 minutes, and then 10ml of Sodium borohydride (NaBH 4 , 0.05 g) aqueous solution slowly dripped in, placed on a stirrer and stirred for 24 hours after completion; after stopping the stirring, put it in a cool place, after the mixed solution was layered with deionized water, extracted the mixed solution in the upper layer to obtain The aqueous solution containing nano-gold particles has an average diameter of the gold nanoparticles below 10nm.

[0049] Add pure water into the batching tank, and at a stirring speed of about 800 rpm, add dispersants, defoamers, film-forming aids, propylene glycol, hydrocarbon ethyl cellulose, pH regulators, etc., and stir until it appears in a gel-like state. Add environmentally friendly inorganic pigments and titanium dioxide fill...

Embodiment 2

[0053] 100ml of auric acid (HAuCl 4 ) aqueous solution mixed with 0.60 g of dodecyltrimethylammonium bromid (Didodecyl-dimethyl ammonium bromid) solution; then placed on a stirrer and stirred at a constant speed for 50 minutes, and then 15ml of Sodium borohydride (NaBH 4 , 0.05 g) aqueous solution is slowly dripped in, and after completion, it is placed on a stirrer and stirred for 18 hours; after the stirring is stopped, it is placed in a cool place, and after the mixed solution is layered with deionized water, the upper mixed solution is extracted to obtain The aqueous solution containing nano-gold particles has an average diameter of the gold nanoparticles below 100nm.

[0054] Add pure water into the batching tank, and add dispersant, defoamer, film-forming aid, propylene glycol, hydrocarbon ethyl cellulose, pH regulator, etc. at a stirring speed of about 1200 rpm, and stir until it appears in a gel-like state. Add environmentally friendly inorganic pigments and titanium...

Abstract

The invention provides a surface processing material, which comprises an emulsion varnish coating and a nanometer noble metal grain; the surface processing material can catalyze oxygen in the indoor air and indoor harmful gas such as formaldehyde, benzene, ammonia, TVOC and others, and accelerates the oxidation-reduction effect, and decompose harmful gas to be carbon dioxide, water and harmless matters; meanwhile, the nanometer noble metal grain cannot participate in any chemical reaction during the process of catalyzing the oxygen and harmful gas; therefore, the nanometer noble metal grain cannot be consumed, the indoor air purification effect can be durably displayed for a long time. Besides, the invention further provides a preparation method of the surface processing material.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a surface treatment material and a preparation method thereof. Background technique [0002] According to statistics, modern humans spend 80% of their time in indoor spaces. Therefore, the cleanliness of indoor air has a very critical impact on human health. Synthetic items enter the home, such as artificial cabinets, artificial wood panels, curtains, sofas, carpets, mattresses, plastics, rubber products, etc. These artificial processed products usually use a lot of adhesives and anti-corrosion to meet the needs of anti-corrosion and insect-proof Agents, usually release formaldehyde, benzene, ammonia, VOC and other volatile harmful gases, and become the source of indoor air pollutants, especially the volatilization period of formaldehyde is as long as 3-15 years, which can cause human eye irritation, respiratory tract Diseases, skin allergies, leukemia, women's menstrual disord...
