Abstract
The invention discloses a rapidly shrinking fusing auxiliary which is applied to helping a fusible alloy in a thermal fuse to shrink and break at a specific temperature. The rapidly shrinking fusing auxiliary is characterized by comprising, in weight percent, 60%-80% of rosin, 5%-15% of shrinking agents, 5%-15% of activating agents and 4%-8% of curing agents. The rapidly shrinking fusing auxiliary can rapidly shrink the fusible alloy, shrinking time ranges from 5.6 seconds to 9.2 seconds, the shrinking speed of the auxiliary is increased by 2-5 times as compared with that of individual hydrogenated rosin needing 26.3 seconds, accordingly, a power supply can be rapidly cut off when the existing thermal fuse for protecting an electric appliance fails in the use process, the electric appliance is protected, and use safety of the electric appliance is improved.
Description
Technical field
The present invention relates in the electronic circuit alloy-type temperature fuse fusible alloy and use the field, relate in particular to a kind of quick contraction disconnected agent of fluxing, be used for helping the Thermal Cutoffs fusible alloy under specified temp, to shrink the auxiliary agent of disconnection.
Background technology
Thermal Cutoffs is the device that one-time action can not reset, and is widely used in the heat protection of equipment, prevents that under the condition of fault one or more positions from reaching dangerous temperature.Existing Thermal Cutoffs is mainly based on alloy-type temperature fuse, constitute with the disconnected agent of fluxing by having low-melting fusible alloy, be encapsulated in the shell of plastics or pottery, under normal operation, fusible alloy keeps being connected with two pins, when Thermal Cutoffs is experienced abnormal heating and reach predetermined melting temperature, the fusible alloy fusing, and under the effect of the disconnected agent of fluxing disconnecting circuit.
At present; existing technical literature; open report or the patent of the disconnected agent aspect of fluxing of also not being correlated with; for now; the mixing of the flux disconnected general simple employing rosin of agent or the rosin esterification product of existing Temperature protection; therefore; its effect is being applied on the electric prospection when use is broken down, because the disconnected agent of fluxing is fast inadequately to the contraction of alloy, and the bigger electric arc of generation; sparkle thereby can produce; phenomenons such as burning; bring certain hidden danger to use, therefore, based on the consideration on the safety; need a kind of quick contraction to help the disconnected agent of fluxing of low-melting fusible alloy; make Thermal Cutoffs under the apparatus failure condition, can when Thermal Cutoffs is sensed the fusing point of temperature arrival fusible alloy, shrink fast; reduce or avoid electric arc, reach the purpose of quick disconnecting circuit.
Summary of the invention
The objective of the invention is, a kind of quick contraction disconnected agent of fluxing is provided, with the disconnected agent of fluxing that solves existing Thermal Cutoffs because the contraction fast use potential problem that brings inadequately.
Technical scheme of the present invention is, a kind of quick contraction disconnected agent of fluxing, and its percetage by weight consists of:
Rosin: 60% ~ 80%;
Contracting agent: 5% ~ 15%;
Activator: 5% ~ 15%;
Curing agent: 4% ~ 8%.
Compound method: an amount of rosin is placed in the reactor that has stirring fuses, begin after the fusion fully to stir, under stirring, it is even to add an amount of activator mix successively, pours an amount of contracting agent again into, when the rosin color in the reactor no longer changes by the time, add curing agent and mix, stir a period of time, when the product in the question response still does not have gas to produce, while hot product is poured in the product groove, cooling namely gets the present invention's disconnected agent of fluxing.
Rosin of the present invention is one or both the combination in Foral, the newtrex.Rosin is the disconnected agent main material of fluxing, its composition accounts for more, purpose is to provide the melting point of disconnected agent of fluxing, so that correspondingly low-melting fusible alloy is used, common rosin, Foral, its softening point is lower, be more suitable for being used in the fusible alloy use of 70 ℃ ~ 120 ℃ of fusing points, newtrex, softening point are higher relatively, are more suitable for being used in the fusible alloy being higher than 150 ℃ of fusing points.
Contracting agent of the present invention is the material with pure amine structure class, relate in particular to the compound that it contains one or more structure-N-C-C-OH, particularly, described contracting agent can be selected from one or more the combination in monoethanolamine, triethanolamine, triisopropanolamine, the oxine.In-N-C-C-OH the structure-OH has bigger chemism, under the rosin fusion temperature namely can with rosin in-the COOH structure carries out esterification, thereby rosin and contracting agent can be coupled together, reach the purpose that the present invention shrinks fast.
Activator of the present invention be selected from in stearic acid, 18 alcohol, the octadecylamine one or more combination.Activator reduces the resistance in the contraction process with the flux flowability of disconnected agent liquid under molten state of raising.18 alcohol, the entrained C of stearic acid
17H
35-group itself has the surface-active effect of raising, and by the effect of contracting agent, the group on the activator can link together with rosin, contracting agent, has further increased shrinkage of the present invention.
Curing agent of the present invention is the anhydrides material of the diacid of 2 ~ 3 carbon atoms in space, and specifically, described curing agent can be selected from a kind of in succinic anhydride, the glutaric anhydride.The acid anhydrides of the diacid of 2 ~ 3 carbon atoms in space has five-membered ring or hexatomic ring of one's own owing on its structure, Stability Analysis of Structures, and the disconnected agent of strengthening fluxing is solidified, and the feasible disconnected agent of fluxing becomes solid, to reach the purpose of conveniently using.
The disconnected agent of fluxing that the present invention prepares shows fusible alloy contractive effect under molten state; the present invention compares with prior art; the contraction speed faster that has to fusible alloy; thereby can solve existing Thermal Cutoffs is used on the electric prospection when use is broken down with the fast speeds deenergization; reach the purpose of protection electrical equipment, improve the use safety of electrical equipment.
