Problems solved by technology

However, its disadvantages are that alcohols have defoaming effect, water-soluble polymers have poor foam stabilization effect, and it is difficult to form large and lasting snow-like foam, and butane and A46 are flammable and explosive, so it is not safe to use

Embodiment 1

[0021] Foaming agent: 0.9 g of sodium lauryl sulfate, 0.6 g of Ninar, and 28.5 g of water. First add sodium lauryl sulfate into water, heat slowly to dissolve, then add Ninar, and stir evenly.

[0022] Propellant: 4g isopentane, 4g difluorochloromethane, 3g n-butane, 10g monochlorodifluoromethane. Mix well. Take a 250ml ordinary aluminum three-piece aerosol can, first fill it with foaming agent, add stirring beads, then seal it, and then fill it with propellant to obtain Feixue aerosol. Shake well before use, and then conduct a spray test. It can spray large snowflakes and fly all over the sky, and the effect is very good. According to GB / T1449-93 aerosol product test method 4.2 test spray mist flammability, the result is non-combustible. The ozone depletion potential (ODP value) calculated on a weighted average basis is 0.014 (the ODP value of the commonly used haloalkane propellant F12+F11 is 1).

Embodiment 2～6

[0024] According to the steps of Example 1, Feixue aerosol was prepared and tested, and the raw materials and quantities of foaming agent and propellant were prepared as shown in Table 1.

[0025] Table 1

[0026]

[0027] The prepared snow aerosol spray test is carried out in the same manner as in Example 1 to observe the snowmaking effect, test the flammability of the spray mist and calculate the ozone depletion potential (ODP value). The results are shown in Table 2.

Abstract

The invention relates to an aerosol, which consists of vesicant and propellant. The vesicant is mixture solution of anionic surfactant and alkyl alcohol amide used as foam stabilizer and solubilizer; the propellant is a compound of alkanes and hydrochloroflurocarbons (HCFC). The aerosol is environment friendly with little impact to the atmospheric ozone layer, has safe use without burning and explosion, has realistic effect for building snowscape and is used for the situations such as happy event and stage set.

Description

technical field [0001] The invention relates to the field of organic chemical industry, in particular to a flying snow aerosol. Background technique [0002] In some festive occasions such as marriage, birthday, housewarming, celebration, etc., or the layout of the stage scene needs to create a scene of heavy snow. In the prior art, an aerosol that can spray a large amount of slab foam is used to create the scene of heavy snow flying. [0003] CN1213685A patent proposes a kind of aerosol that can produce artificial snowflake, is to make foaming agent with anionic surfactant, nonionic surfactant and amphoteric surfactant, water-soluble polymer is made foam stabilizer, is made booster with alcohols. Solvent, made with butane as propellant and some spices. Because the aerosol uses butane as a propellant, butane is flammable and explosive, and it is difficult to avoid sparks on festive occasions, so it is easy to cause fires, explosions and other accidents when used, and even ...
