Description
Technical Field
The invention relates to the field of daily chemical articles, in particular to a long-acting mite-killing spray and a preparation method thereof.
Background
Mites are widely distributed in dark corners of a room, carpets, mattresses, pillows, sofas, air conditioners, summer sleeping mats and the like, wherein the mattresses are most suitable for the growth and propagation of the mites. The corpse, secretion and excrement of the mites are easy to become allergen, influence sleep, cause allergic rhinitis, allergic conjunctivitis, allergic asthma and allergic dermatitis, and influence the daily work and life of people.
The existing mite removing mode mainly comprises mite removing by a mite removing instrument and mite removing by spraying. The mite removing instrument mainly adopts the functions of beating, dust absorption and ultraviolet rays to remove mites and sterilize. However, the mite killing instrument cannot inhibit the growth of mites, only removes the existing mites, and the mites breed again after a period of time, so that the cleaning speed cannot be equal to the breeding speed of the mites; and the mite removing instrument has higher cost, inconvenient use and time and labor consumption in operation.
Compared with a mite removing instrument, the mite removing spray has the advantages of low cost and convenience in use. The existing mite-killing spray is generally composed of water, a surfactant, an antibacterial mite-killing component and a functional additive. For example, patent 201810582579.5 discloses a portable spray for killing mites, which comprises 20-40 parts of acrylic lanolin, 10-20 parts of sodium cocoate, 3-6 parts of sorbitan, 2-6 parts of salicylic acid, 1-2 parts of an antibacterial agent, 3-5 parts of a plant extract, 1-1.5 parts of essence, and 10-20 parts of deionized water. Patent 201810581715.9 discloses a yoga mat mite-killing spray, which comprises 20-40 parts of linear alkylbenzene, 10-20 parts of sodium cocoate, 3-6 parts of sodium dodecyl benzene sulfonate, 2-6 parts of licorice extract, 1-2 parts of an antibacterial agent, 3-5 parts of sorbitol, 1-1.5 parts of essence and 10-20 parts of deionized water. Patent 201810533785.7 discloses a spray for killing bacteria and mite, which comprises nonionic surfactant 13-15 parts, citric acid 10-20 parts, chlorhexidine hydrochloride 3-6 parts, sodium lauroyl glutamate 2-6 parts, antibacterial agent 1-2 parts, plant extract 3-5 parts, essence 1-1.5 parts, and deionized water 10-20 parts.
However, the existing mite removing spray generally adopts a single mite removing medicament or plant antibacterial mite removing component, the effect of inhibiting the growth of mites is not lasting, and long-acting mite removal cannot be realized.
