Abstract
The present invention is one kind of non-aqueous environment friendly detergent and its preparation process. The detergent includes hydrogenous halogenated hydrocarbon as the main component, alkane modifier and alcohol assistant. It has low ozone depletion potential, no residue and capacity of cleaning complicated metal and non-metal products. It may be used to replace Freon CFC-113 for precise cleaning in aviation, electronic and other fields.
Description
Technical field
The present invention relates to a kind of environment-friendly cleaning agent, non water system environment-friendly type cleaning agent of particularly a kind of replacement fluorine Lyons CFC-113 and preparation method thereof.
Background technology
Because fluorine Lyons CFC-113 is the material of universally acknowledged destruction atmospheric ozone layer, be decided to be restriction, subdued and finally completely forbidden use.At present, the clean-out system type of CFC alternative-113 mainly contains both at home and abroad: water system clean-out system, half water system clean-out system and non-water system clean-out system.For containing multiple metal and the nonmetallic complicated occasion of cleaning, consider the susceptibility of its material to aqueous corrosion, any residue can not be arranged after the cleaning and clean the requirements of using such as temperature, have only non-water system surrogate to consider.
The more non-water system surrogate of foreign study is that fluorine is a clean-out system, mainly contains HCFC (hydrogeneous cfc), HFC (hydrogen-containing carbon fluorochemical), HFE (hydrogen fluorine ether) etc. are several.The characteristics of these a few class surrogates are volatile removal, noresidue, and have less ozone layer destroying ability.The current development direction that is in Dupont (Dupont) company of clean-out system research and production leading position is exactly the HFC clean-out system, and its product has XF, XM, the MCA of Vertrel series etc., and wherein main effective ingredient is Decafluoropentane and anti-Ethylene Dichloride; Also have 3M company, its main direction is a fluorine ether clean-out system, and product has Novec series, as HFE-7100, HFE-7100IPA etc.It much is the substitute of CFC that HFC and HFE have, and price is very expensive, generally at 35.0～70.0 ten thousand yuan/T, though E.I.Du Pont Company and 3M company try hard to reduce cost to enlarge output, but estimates not have within following 10 years the change of the order of magnitude.In addition, Japan, German also in the research of carrying out the CFC-113 surrogate, from relevant document and product information, not only cost an arm and a leg (25.0～40.0 ten thousand yuan/T), and because problems such as material compatibility can't be applied to contain multiple metal and nonmetallic complicated cleaning of cleaning occasion.
Domestic research for non-water system surrogate also has report, the direction of research also is a few class materials such as HCFC, HFC, but product is relatively poor to the consistency of various types of materials, and is especially all the more so to non-metallic material, can not satisfy to contain multiple metal and nonmetallic complicated cleaning requirement of cleaning occasion.
Summary of the invention
The objective of the invention is to research and develop the novel environment friendly clean-out system of a kind of fluorine Lyons CFC-113 of alternative present use, has low ODP, do not leave any residue after the cleaning, satisfy multiple metals such as containing copper nickel calcium powder alloy, silver solder ∏ CP37.5, superalloy steel wire, 3J21 (cold), 7804 ointment, 7805 ointment, special 221 ointment, fluoroplastics FC-5 and nonmetallic complicated cleaning requirement of cleaning occasion.
Technical solution of the present invention is: a kind of non water system environment-friendly type cleaning agent is characterized in that each component ratio is:
1, main solvent: 60～75% (v/v);
2, properties-correcting agent: 5～15% (v/v);
3, auxiliary agent: 20～30% (v/v).
Its preparation method is:
(1) main solvent is pumped into the stirring reaction device with surge pump after, under low whipping speed 30-90 rev/min the condition, by main solvent: properties-correcting agent 13～15: 1 proportional quantity (volume ratio) is prepared: the main solvent of measuring 13～15 volumes is earlier poured reaction vessel into, the properties-correcting agent of measuring 1 volume then slowly adds in the reactor, while under the pressure of 0.1～3.0Mpa, feed in raw material under 0～30 ℃ the temperature and stir;
(2) wait to add properties-correcting agent after, after pressure is adjusted to 0.5-1.0Mpa, temperature is adjusted to 10～20 ℃, continue mixed solution was stirred 2～10 hours, obtain colourless mixed transparent solution;
(3) the colourless mixed transparent solution that above step is obtained is prepared by 3～5:1 proportional quantity (volume ratio) with auxiliary agent: the auxiliary agent of measuring corresponding volume according to the volume of mixed solution is poured reactor into, under the pressure of-1.0～2.0Mpa, stirred under 10～20 ℃ the temperature 2～6 hours, and directly obtained product.
The present invention's advantage compared with prior art is:
1, the ODP of environment-friendly cleaning agent greatly reduces the influence to environment less than 1/10 of fluorine Lyons CFC-113.
2, tens of kinds of metals adopting of environment-friendly cleaning agent and test are simultaneously compatible with non-metallic material, especially solved the consistency technological difficulties of solvent and metal and elastomeric material.
3, compare the non-water system surrogate of existing fluorine Lyons CFC-113, price is lower.
