Description

A kind of binary package non-combustible air freshener and preparation method thereof

technical field

The invention relates to a binary package non-combustible air freshener, belonging to the field of aerosol research; in particular, it relates to an environment-friendly, safe and convenient air freshener.

Background technique

At present, the domestic production of aerosols in 2017 is about 2.2 billion, of which daily chemicals account for about 56.4%. In recent years, there has been an increasing trend. Currently, one-yuan packaging in my country is still dominant, and it is difficult to reverse in the short term. Using a one-piece packaging structure, the dosage and propellant are mixed and stored in the aerosol can. The stability of the product needs to consider many factors, such as the corrosion and anti-corrosion of the aerosol can, the stability of the material and liquid, the stability of pressure, The flammability and explosiveness of products are strictly restricted by environmental protection and safety regulations. At present, the industry is striving to improve it, but it needs to be improved day by day.

At present, in the aerosol industry, cosmetics, food, and medicine have continued to use binary packaging technology, and household products are still in the blank stage. With the development of the national economy and the improvement of people's material living standards, people's requirements for the surrounding environment are also getting higher and higher. The amount of air freshener is mainly used in homes, offices, toilets, smoking areas, etc., and has high practical value. SC Johnson first developed water-based air fresheners, which changed the previous monopoly market situation of alcohol-based air fresheners. Water-based air fresheners have been recognized by the public due to their environmental protection and greatly reduced combustion possibilities. However, water-based air fresheners have In essence, the air freshener is still an aerosol that uses combustible substances such as LPG or DME as propellants, which causes this water-based air freshener to still have the possibility of burning, and there are hidden dangers in use and transportation; the problem is not the choice of Non-combustible gases such as CO2, R134A can be used as a propellant; CO2 pressure is very high, and the filling amount is not allowed to exceed 15g during normal production, which is difficult to produce, and because of its water solubility and high pressure, it is made into aerosol The atomization performance is poor, and it is easy to be water column type. However, R134A is expensive, and the pressure changes greatly with temperature. Too many are not suitable for the general public.

Compared with the one-dimensional packaging technology, the binary packaging technology does not emit propellants during use to reduce VOCs emissions, and is safer to use. It is a safe packaging technology that changes aerosols as "flammable product labels". Find a breakthrough under the dual pressure of environmental protection and environmental protection.
