2/ s.
The average grain diameter of the primary particle of aerosil is 7～40nm, and corresponding specific area is 380～50m
2/ g.
The present invention also provides a kind of Thermal Cutoffs element that contains described flux, this element comprises electrode slice, plastics counterdie, fuse, flux and plastic covered film, wherein flux is coated in plastics counterdie inboard, fuse places on the flux, the fuse two ends are connected with electrode slice respectively, the electrode slice other end stretches out outside the plastics counterdie, and above-mentioned parts outside is coated by the plastic covered film, and the integral heat pressure moulding.
Described electrode slice is a nickel electrode, its link copper coating; Described fuse is the low-melting alloy silk.
Contribution of the present invention is; by rosin, dimethicone and aerosil are carried out organic assembling; make flux of the present invention compare with traditional flux; the thermal cut performance of fuse prepared therefrom obviously improves; and the pattern of fusing back fuse has had tangible improvement; the lithium ion battery of making thus obviously improves with the fusing performance of electrical fuse element, and the pattern of fusing back fuse also further improves, thereby high-energy battery is formed the better protection effect.Characteristics of the present invention more specifically show:
One, because of containing dimethicone in the flux of the present invention, because of it has the electrical insulation capability and the thermal endurance of high heat conductivility, excellence, the flash-point height, solidifying point is low, can be-50 ℃～200 ℃ following long-term works, performance such as viscosity-temperature coefficient is little can be improved and extraneous heat conduction, therefore the Thermal Cutoffs element of being made by the flux that contains dimethicone can improve Thermal Cutoffs element sensitiveness to electric current under hot conditions, improves the thermal cut performance of Thermal Cutoffs accordingly; On the other hand since the dimethicone surface tension little, have certain polarity and can form wetting preferably and keep the good interface performance Thermal Cutoffs, in the process of Thermal Cutoffs fusing, form effective towing to Thermal Cutoffs, thereby give full play to the effect of flux, improve the fusing performance of Thermal Cutoffs.
Two, contain a certain amount of aerosil in the flux of the present invention, its on the one hand can regulation system viscosity, the stability of increase system forms the three-dimensional net structure of aerosil, the hot thixotroping structure that the system of giving is certain on the other hand in system.
Description of drawings
Fig. 1 is a Thermal Cutoffs component structure schematic diagram of the present invention.
Embodiment
The following example is to further explanation of the present invention and explanation, and the present invention is not constituted any limitation.
Thermal Cutoffs flux of the present invention is that the aerosil by the dimethicone and 0.5～16 (weight %) of the rosin of 50～80 (weight %) or modified rosin, 10～40 (weight %) mixes.
Wherein, rosin is transparent, hard crisp solid matter, and to maroon, density is 1.05～1.10g/cm to color by faint yellow
3, softening point is at 60～85 ℃, and boiling point is about 300 ℃.Mainly becoming of rosin is mixture of isomers such as rosin acid, neoabietic acid, isodextropimaric acid, contains carboxyl and unsaturated double-bond in the molecular structure.Resulting product becomes modified rosin after carrying out chemical reaction on the unsaturated double-bond in above-mentioned rosin acid molecule, mainly contains Foral, disproportionated rosin, newtrex, maleic rosin etc.Especially the lower rosin of softening point is flux matrix preferably as common rosin.The content of rosin is generally 50～80%, and its preferred content is 60～70%.
Dimethicone is a kind of colourless transparent liquid, has various viscosity, and nontoxic, nothing is smelt, and does not have corrosion.Kinematic viscosity range under 25 ℃ of the used dimethicones is 1000～12500mm
2/ s: when viscosity is lower than 1000, the stability of system is too poor; When viscosity is higher than 12500, then viscosity is too big, is difficult to system is adjusted to pastel, is unfavorable for coating.The consumption of dimethicone is generally 10～40%, and its preferred content is 30～40%.When consumption was lower than 10%, the viscosity of system was excessive, was difficult to form pastel, was unfavorable for coating.When consumption surpasses 50%, on the one hand because the viscosity of system is less, flux is easy to flow, cause the difficulty of encapsulation, influence the sealing of Thermal Cutoffs element, because silicone oil has good thermal conductivity heat can be transmitted on the encapsulating film fast in the process of big current fusing takes place Thermal Cutoffs, cause the destruction of film, thereby have certain potential safety hazard on the other hand.In addition, except above-mentioned dimethicone, can also select silicone oil products such as diethyl silicone oil, phenyl methyl silicone oil for use.
Aerosil is by silicon tetrachloride hydrolysis and making in the hydrogen-oxygen flame.The aerosil microscopic pattern is spherical, and X ray is unformed particle down.The average grain diameter of the primary particle of aerosil is 7～40nm, and corresponding specific area is 380～50m
2/ g.Add the aerosil dispersion suspension a spot of, that surface area is very big in silicone oil on the one hand, can improve its surface tension, further improve the towing of Thermal Cutoffs in fusing process; Hydrophobicity siloxane unit and hydrophily silanol unit are contained in Qiu Xing aerosil surface on the other hand, wherein the siloxane unit of hydrophobicity and the siloxane structure in the dimethicone are similar, interaction by the two realizes the dispersion of aerosil in dimethicone, also because the interaction of hydrogen bond between the silanol groups between the adjacent aerosil particle forms three-dimensional structure.Therefore, the consumption of aerosil is to determine that by the viscosity three of the specific area of the viscosity of used silicone oil, aerosil and final system is common consumption is 5%～40% of a silicon oil dosage usually.
Can be made into Thermal Cutoffs element of the present invention by above-mentioned flux, consult Fig. 1, this element comprises electrode slice 1, plastics counterdie 2, fuse 3, flux 4 and plastic covered film 5, wherein flux 4 is coated in plastics counterdie 2 inboards, low-melting alloy fuse 3 places on the flux 4, and the fuse two ends are connected with nickel electrode 1 respectively, and the electrode slice other end stretches out outside the plastics counterdie, above-mentioned parts outside is coated by plastic covered film 5, and the integral heat pressure moulding.The fusing performance of Thermal Cutoffs element that contains this flux is as shown in table 1.
Table 1
The operation principle of Thermal Cutoffs element of the present invention is: the Thermal Cutoffs element that is connected on usually in the battery circuit is short-circuited or during other faults when battery circuit, to cause the current anomaly of circuit to raise, because the thermal effect of electric current will cause the temperature of Thermal Cutoffs constantly to raise, when arriving the fusing point of low-melting alloy silk, self fusing cut-out electric current will take place in Thermal Cutoffs, thereby form protection, promptly common " overcurrent protection " to battery; On the other hand, when causing battery temperature to be elevated to the fusing point of low-melting alloy owing to other reasons, self fusing cut-out electric current will take place in same Thermal Cutoffs, thereby form the protection to battery, promptly usually said " overtemperature protection ".Therefore, the Thermal Cutoffs element that can make different size by the composition and the size of change low-melting alloy silk.
