Problems solved by technology

[0003] The masking method does not fundamentally solve the odor, and the emission of the odor will affect human health; the adsorption method is suitable for the treatment of malodorous gases with low concentration and high purification requirements, and the adsorbent needs to be replaced regularly. Solve the root cause of odor; the chemical method uses methods such as neutralization and oxidation of chemical substances to make effective deodorant components chemically react with odorous substances directly, but some chemical substances will cause corrosion to aircraft metal materials, or to some rubber materials. In order to meet the airworthiness requirements of the aircraft, the relevant material compatibility evaluation should be carried out before it can be used
The biological deodorization method cannot be applied to the special environment of the aircraft toilet

Embodiment 1

[0018] An aircraft toilet deodorant, consisting of the following parts by weight: 0.5 part of lauryl methacrylate, 0.03 part of lauryltrimethylammonium chloride, 0.8 part of Tween-80, and 8 parts of isopropanol , 0.2 parts of citral, 0.1 parts of benzotriazole, and 93.8 parts of water.

[0019] Lauryl methacrylate, dodecyltrimethylammonium chloride, Tween-80, and citral should be added to isopropanol respectively during preparation, and stirred continuously to fully dissolve it as an oil phase. Add benzotriazole into water and stir to make it dissolve completely, as the water phase. Then add the oil phase to the water phase while stirring, and add triethanolamine to adjust the pH to 7.2.

Embodiment 2

[0021] A deodorant for aircraft toilets, consisting of the following parts by weight: 2 parts of lauryl methacrylate, 0.08 part of dodecyltrimethylammonium chloride, 0.1 part of AEO-9, 9 parts of isopropanol, 0.4 parts of citral, 1 part of benzotriazole, 87.5 parts of water.

[0022] When preparing, add lauryl methacrylate, dodecyltrimethylammonium bromide, AEO-9, and citral to isopropanol respectively, stir continuously to dissolve them fully, and use them as the oil phase. Add benzotriazole into water and stir to make it dissolve completely, as the water phase. Then add the oil phase to the water phase while stirring, and add triethanolamine to adjust the pH to 7.8.

Embodiment 3

[0024] An aircraft toilet deodorant, which is composed of the following parts by weight: 0.1 part of lauryl methacrylate, 0.02 part of isothiazolinone, 0.8 part of AEO-9, 5 parts of 1,2-propylene glycol, and 0.1 part of peppermint oil , 2 parts of polyaspartic acid, 92.1 parts of water.

[0025] When preparing, lauryl methacrylate, isothiazolone, AEO-9, and peppermint oil should be added to 1,2-propanediol respectively, stirred continuously to fully dissolve, and used as the oil phase. Add polyaspartic acid into water and stir to dissolve it completely to form the water phase. Then add the oil phase into the water phase while stirring, and add NaOH solution to adjust the pH to 7.4.

Abstract

The invention discloses an airplane lavatory deodorizer, which is prepared from the following substances in parts by weight: 0.1 to 5 parts of deodorizing compound, 0.1 to 1 part of bactericide, 0.5 to 3 parts of surface active agent, 3 to 10 parts of solubilizer, 0.001 to 1 part of spice, 0.2 to 2 parts of corrosion inhibitor and 78 to 96 parts of water. The airplane lavatory deodorizer disclosed by the invention can quickly remove varieties of peculiar smell and has a good effect on general peculiar smell of ammonia gas, hydrogen sulfide, methyl mercaptan and the like in a lavatory; meanwhile, sterilizing components contained in the airplane lavatory deodorizer can effectively restrain bacterial breeding in an airplane lavatory, and odor generation is fundamentally reduced; the airplane lavatory deodorizer has the characteristics of high flash point and incombustibility, has very good material compatibility with varieties of metal, non-metal, painted faces and varieties of rubber, can be directly sprayed and applied to a sealed space of the airplane lavatory and has no side effects on an airplane structure.

Description

technical field [0001] The invention relates to a deodorant, in particular to a safe, efficient and environment-friendly aircraft toilet deodorant. Background technique [0002] The toilet deodorants and deodorizing methods currently used mainly use spices to cover the odor, and there are also methods of physical adsorption, which absorb the odorous gas molecules by placing an adsorbent, thereby reducing or eliminating the odor. By adding substances with deodorizing function, the odor gas can be directly eliminated through chemical reaction, which has the characteristics of fast and efficient. There are also some biological deodorization methods, which mainly degrade malodorous substances through microorganisms. Common biological deodorization methods use biological filtration deodorization method and activated sludge deodorization method. [0003] The masking method does not fundamentally solve the odor, and the emission of the odor will affect human health; the adsorption...
