Abstract
The invention discloses a screw loosening agent, which comprises the following components in part by weight: 60 to 80 parts of hydrocarbon refrigerant, 10 to 25 parts of hydrocarbon solvent oil, 3 to 5 parts of synthetic ester and 5 to 10 parts of sulfonate rust inhibitor, wherein the hydrocarbon refrigerant is R-433b or tetrafluoroethane HFC-R134a or a mixture of the R-433b and tetrafluoroethane HFC-R134a; the hydrocarbon solvent oil is one or a mixture of C10 to C16 alkane; the synthetic ester is trimethylolpropane; and the sulfonate rust inhibitor is sulfonate. In the invention, according to the principle of expansion and contraction, a fastener which is rusted and cannot be loosened is subjected to flash freezing in a detachment process to make a required gap between structural members bonded into a whole due to rust corrosion, so that the solvent oil, synthetic ester, sulfonate and the like, which are sprayed out together with the refrigerant, can permeate into the gap for derusting and lubricating; and thus, both the fastener and the structural members get necessary repair and the loosening of the screw is realized naturally.
Description
Technical field
The present invention relates to a kind of screw loosening agent, be meant a kind of loosening fast screw loosening agent of metal fastenings such as screw that can make corrosion especially.
Background technology
With the closely-related railway of social development, bridge, electric wire steelwork, vehicle and all kinds of factories and miness machineries etc., main fixedly connected between member with screw.In daily laid-up operation, the fastening pieces such as screw that corrosion can't be become flexible are used always ways processing such as machine oil immersion, the oxygen blast of acid material burn into, sawing.Waste time and energy and the cost height, efficient is low.At present, existing screw loosening agent product is sold on the market, for construction brings convenience.But since raw materials used mostly be have infiltration, derust, the industrial raw material of lubrication, it is more expensive to exist product price, the speed of becoming flexible screw waits shortcoming more slowly, it is applied be restricted.
Summary of the invention
The purpose of this invention is to provide a kind of back instant effect, loosening effective screw loosening agent of using.
Designed a kind of screw loosening agent according to above-mentioned purpose, the recipe ingredient of this loosening agent is: carbon-hydrogen refrigerant, hydrocarbon solvent oil, synthetic ester, sulphonate rust-preventive agent;
Said each component is counted by weight, carbon-hydrogen refrigerant 60-80 part, hydrocarbon solvent oil 10-25 part, synthetic ester 3-5 part, sulphonate rust-preventive agent 5-10 part; Wherein,
Said carbon-hydrogen refrigerant is one or both the mixing among R-433b or the Tetrafluoroethane HFC-R134a,
Said hydrocarbon solvent oil is C
10～C
16The mixing of one or both in the alkane or three kinds,
Said synthetic ester is a trihydroxy-propane oleic acid ester,
Said sulphonate rust-preventive agent is sulphonate.
Ultimate principle of the present invention is the principle of expanding with heat and contracting with cold that utilizes people to know; In unloading process, earlier the fastening piece that can't become flexible because of corrosion is given anxious freezing; Make it compelled shrink by force, make and produce necessary gap between the structural part that is bonded into one because of corrosion, realized rust cleaning and lubricated in the slit so the solvent oil that sprays simultaneously with refrigeration agent, synthetic ester, sulphonate etc. penetrate into immediately; Make fastening piece and structural part all obtain necessary reparation, so far loosening the becoming of screw must.
Embodiment
The urgency that purport of the present invention provides a kind of " not tearing the screw that does not fall open " is frozen the screw loosening agent, to solve the predicament that causes structural part to dismantle because of the corrosion cohesive that exposes to the sun and rain, there was dampness in the air causes.Designed a kind of screw loosening agent, the recipe ingredient of this loosening agent is for this reason: carbon-hydrogen refrigerant, hydrocarbon solvent oil, synthetic ester, sulphonate rust-preventive agent; Said each component is counted by weight, carbon-hydrogen refrigerant 60-80 part, hydrocarbon solvent oil 10-25 part, synthetic ester 3-5 part, sulphonate rust-preventive agent 5-10 part; Wherein, carbon-hydrogen refrigerant is one or both the mixing among R-433b or the Tetrafluoroethane HFC-R134a, and hydrocarbon solvent oil is C
10～C
16A kind of in the alkane or several mixing be isoparaffin or normal paraffin or take off a kind of in the aromatic hydrocarbon or several mixing, and said synthetic ester is a trihydroxy-propane oleic acid ester, and sulphonate rust-preventive agent is sulphonate.Below in conjunction with embodiment this is further detailed with bright.The variation of following proportioning can cause the characteristic between specific product to have a little difference, but can not influence concrete function.
Embodiment 1
Adopt R-433b or 80 parts of HFC-R134a, C
10～C
1610 parts of alkane, 3 parts of trihydroxy-propane oleic acid esters, 7 parts in sulphonate.
Embodiment 2
Adopt R-433b or 70 parts of HFC-R134a, C
10～C
1617 parts of alkane, 4 parts of trihydroxy-propane oleic acid esters, 9 parts in sulphonate.
Embodiment 3
Adopt R-433b or 60 parts of HFC-R134a, C
10～C
1625 parts of alkane, 5 parts of trihydroxy-propane oleic acid esters, 10 parts in sulphonate.
Embodiment 4
Adopt R-433b and HFC-R134a each 40 parts, C
10～C
1610 parts of alkane, 3 parts of trihydroxy-propane oleic acid esters, 7 parts in sulphonate.
In the material that the present invention adopts, sulphonate has detergent-dispersant additive class speciality, is alkalescence, calcium contents is high, and is peace and quiet effective to greasy filth; R433b is environmental protection refrigerant and also has certain lubricity; HFC-R134a is an environmental protection refrigerant; Trihydroxy-propane oleic acid ester belongs to the polyol ester class, and thermotolerance is better, and sticking warm nature is good, and lubricity is outstanding, and is not volatile, is normally used for metalworking fluid and preparation medium; C
10～C
16Alkane is oiliness, is used to lubricate.
