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 invention relates to a screw loosening agent, in particular to a screw loosening agent capable of quickly loosening rusted metal fasteners such as screws and the like.
Background
The components of railways, bridges, wire iron and steel frames, vehicles, various industrial and mining machines and the like closely related to the social development are mainly fixedly connected by screws. In the daily disassembly and repair operation, fasteners such as screws which cannot be loosened due to corrosion are treated by methods such as engine oil soaking, acid material corrosion, oxygen blowing, sawing and the like. Time and labor are wasted, the cost is high, and the efficiency is low. At present, screw loosening agent products are sold in the market, and great convenience is brought to construction. However, the raw materials used are industrial materials with functions of infiltration, derusting and lubrication, and the defects of high product price, low screw loosening speed and the like exist, so that the popularization and the application of the screw loosening machine are limited.
Disclosure of Invention
The invention aims to provide a screw loosening agent which takes effect quickly and has good loosening effect after being used.
The screw loosening agent is designed according to the aim, and comprises the following components in parts by weight: hydrocarbon refrigerant, hydrocarbon solvent oil, synthetic ester and sulfonate antirust agent;
the components comprise, by weight, 60-80 parts of hydrocarbon refrigerant, 10-25 parts of hydrocarbon solvent oil, 3-5 parts of synthetic ester and 5-10 parts of sulfonate antirust agent; wherein,
the hydrocarbon refrigerant is one or the mixture of two of R-433b or tetrafluoroethane HFC-R134a,
the hydrocarbon solvent oil is C10～C16One or a mixture of two or three of the alkanes,
the synthetic ester is trihydroxypropane oleate, and the synthetic ester is trihydroxypropane oleate,
the sulfonate rust inhibitor is a sulfonate.
The basic principle of the invention is to utilize the well-known principle of expansion with heat and contraction with cold to quickly freeze the fastening piece which can not be loosened due to corrosion in the process of disassembly, so that the fastening piece is forced to forcibly contract, necessary gaps are generated between structural parts which are bonded into a whole due to corrosion, then the solvent oil, synthetic ester, sulfonate and the like sprayed out simultaneously with the refrigerant immediately permeate into the gaps to realize rust removal and lubrication, the fastening piece and the structural parts are necessarily repaired, and the loosening of the screw is inevitable.
Detailed Description
The invention aims to provide a quick-freezing screw loosening agent for 'undetachable screws' so as to solve the problem that structural parts cannot be disassembled due to rustiness and adhesion caused by sun, rain and air humidity. Therefore, the screw loosening agent is designed, and the loosening agent comprises the following formula components: hydrocarbon refrigerant, hydrocarbon solvent oil, synthetic ester and sulfonate antirust agent; the components comprise, by weight, 60-80 parts of hydrocarbon refrigerant, 10-25 parts of hydrocarbon solvent oil, 3-5 parts of synthetic ester and 5-10 parts of sulfonate antirust agent; wherein the hydrocarbon refrigerant is one or mixture of two of R-433b and tetrafluoroethane HFC-R134a, and the hydrocarbon solvent oil is C10～C16Mixtures of one or more of the alkanes, i.e. of one or more of the isoparaffins, normal alkanes or dearomaticsAnd mixing, wherein the synthetic ester is trihydroxy propane oleate, and the sulfonate antirust agent is sulfonate. The present invention will be described in further detail with reference to examples. Variations in the ratios described below can result in some differences in characteristics between specific products, but do not affect specific functions.
Example 1
Adopts 80 portions of R-433b or HFC-R134a 80 and C10～C1610 parts of alkane, 3 parts of trihydroxy propane oleate and 7 parts of sulfonate.
Example 2
Adopts R-433b or HFC-R134a 70 parts and C10～C1617 parts of alkane, 4 parts of trihydroxy propane oleate and 9 parts of sulfonate.
Example 3
Adopts R-433b or HFC-R134a 60 parts and C10～C1625 parts of alkane, 5 parts of trihydroxy propane oleate and 10 parts of sulfonate.
Example 4
40 parts of each of R-433b and HFC-R134a and C10～C1610 parts of alkane, 3 parts of trihydroxy propane oleate and 7 parts of sulfonate.
In the substances adopted by the invention, the sulfonate has the characteristics of a detergent dispersant, is alkaline, has high calcium content and has good cleaning effect on oil sludge; r433b is an environment-friendly refrigerant and has certain lubricating capacity; HFC-R134a is an environment-friendly refrigerant; trihydroxy propane oleate belongs to polyol esters, has good heat resistance, good viscosity-temperature property, outstanding lubricating property and difficult volatilization, and is generally used for metal processing oil and chemical fiber oil; c10～C16The alkanes are oily and are used for lubrication.
