Abstract
A process for preparing durable scent by radiation method includes such steps as mixing the scent solution with hydrophobic or hydrophilic high-molecular polymer, such as polyethanediol methylacrylate, filling N2 in the mixture and radiating by Co 60 gamma-ray at -78 deg.C.
Description
Technical field
The atomic energy science technology is used, RADIATION PROCESSING field, Chinese book classification TL99, subject classification number 490.55.
Background technology
Perfume has spice and solvent composition, and perfume molecules spreads along with solvent evaporation, generally begins thick flavor, and just perfume molecules is distributed with solvent and spread, and clean when solvent evaporation, fragrance also disappears.Existing commercially available perfume spills in also keeping 2 hours on one's body, and is shorter in the retention time in summer, prolongs the diffusion time of perfume molecule, also just kept fragrance.It is to make carpet with microencapsulation method extraordinary to become the mould material to make mosquito-repellent perfume with perfume or with selecting for use that current fixedly perfume molecules makes its method that slowly discharges, but does not see human long-acting perfume (see adnexa for details and look into new projects' statement)
Summary of the invention
The present invention seeks to propose radiation method for preparing long-acting perfume at the problems referred to above, it is characterized in that adopting a kind of high molecular polymer monomer such as hydrophobicity methacrylate to mix with 0.01%-0.1% concentration with natural essence, (available dry ice-alcohol mixed solution) descends irradiation dose 10-15kGy under-78 ℃ then, the irradiation dose unevenness is less than 1.5, solution molecule can be fixed in the high molecular polymer monomer, make its chronic release, keep more than 6 hours.
The high molecular polymer monomeric species has hydrophobicity or hydrophilic, is decided by fragrance formulations and selects one of them; Concentration as the concentration of perfume height, needs the retention time long, and is then available 0.1%, otherwise can be reduced to 0.01%; Irradiation dose, as the high available 15kGy of perfume concentration, on the contrary then low.
If predose charges into nitrogen in perfume, replace in the perfume then better effects if of air with nitrogen.
Description of drawings
Fig. 1 is a radiation method for preparing long-acting perfume technological process block diagram.
The high molecular polymer monomer is selected, according to perfume character, the fat-soluble hydrophobicity of selecting, the water-soluble hydrophilic monomer that selects, monomer consumption are the 0.01%-0.1% of perfume volume, according to perfume concentration height, need to keep the fragrance time long, then select 0.1% proportioning, on the contrary optional 0.01% proportioning, mix, in-78 ℃ of lower using60Co gamma-rays or 9-10MeV electron beam rays for irradiation, Irradiation dose 10-15kGy, the high 15kGy that uses of monomer concentration, concentration is low uses 10kGy, and the irradiation dose unevenness is less than 1.5.
Specific embodiments
Water soluble rose essence 1000ml places the 1000ml volumetric flask, add hydrophilic polymer monomer such as polyethylene glycol methacrylate-styrene polymer class monomer 1ml, mix homogeneously, this bottle put into thermos flask 20,000 ml volumes and that double-layer vacuum is arranged, put into dry ice and alcoholic solution in the thermos flask, make its temperature keep-78 ℃, use
60Co γ or 9-10MeV electron beam ray carry out irradiation, irradiation dose 15kGy, and the irradiation dose unevenness, by dilution in 10: 1, is long-acting rose water slow release and puts solution behind the irradiation less than 1.5, and fragrance keeps more than 6 hours.
Claims (2)
1. a radiation method prepares the method for long-acting perfume, it is characterized in that adding the high molecular polymer monomer in perfume, and consumption is the 0.01-0.1% of perfume volume, mixes, and with dry ice, alcohol mixeding liquid, makes it cool to-78 ℃, uses
60Co γ or 9-10MeV electron beam ray carry out irradiation, irradiation dose 10-15kGy, and the irradiation dose unevenness is less than 1.5, and radiation polymerization becomes long-acting perfume, and fragrance keeps more than 6 hours.
2. according to the method for claim 1, it is characterized in that in perfume, monomer mixture, charging into nitrogen before the radiation, replace wherein air.
