Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a test device for easily saponifiable chlorine in epoxy resin. Background Technique

[0002] Epoxy resin has good physical and mechanical properties, electrical insulation properties and chemical corrosion resistance, and is widely used in fields such as coatings, adhesives, electronic and electrical packaging materials, and composite matrix resins. During the synthesis of epoxy resin, incomplete reaction or insufficient post-treatment will cause residual chlorine-containing impurities such as easily saponifiable chlorine, difficultly saponifiable chlorine, and chloride ions in the reaction product. The easily saponifiable chlorine in epoxy resin exists in the resin in the form of chloroalcohol ether, and its structure is unstable. Under the action of high temperature, high humidity and amine curing agents, free chloride ions will be released. These free chloride ions will promote the dissolution reaction of metals such as copper in microelectronic circuits, accelerate ion migration, greatly affect the performance of semiconductor components, and affect the use safety performance and service life of integrated circuits. Therefore, in order to meet the application requirements of ultra-large-scale integrated circuits and microelectronic packaging, it is necessary to test the easily saponifiable chlorine in epoxy resin.

[0003] The test process of easily saponifiable chlorine in epoxy resin includes a pretreatment process and a test operation process. The pretreatment process requires using reagents to dissolve the sample and heating and stirring the sample to make the sample and reagents mix more quickly and evenly. At present, in the analysis and test of easily saponifiable chlorine in epoxy resin, the pretreatment process and the test operation process need to be carried out on different devices respectively, which occupies a large space and is inconvenient to operate; when dropping different reagents, the ultrasonic wave is selected to dissolve and stir the sample. This dissolution method has the problem of uneven mixing of the sample and reagents, and is only suitable for the dissolution of liquid samples or solid samples with a small sampling amount, and the applicable range is small; when heating the sample, a hot plate is used for heating, and the heating temperature uniformity and stability are poor, and there is also a problem that when the operator transfers the conical flask, the operator directly touches the heated conical flask and scalds the operator.

The pretreatment unit 4 includes a magnetic bearing member 31, and a heating medium for heating the sample inside the conical flask 2 is contained inside the magnetic bearing member 31, and heat energy can be generated by magnetic induction between the magnetic bearing member 31 and the magnetic member.

The conical flask 2 is arranged on the base 1 in a liftable manner, which is convenient for heating or cooling the sample inside the conical flask 2 and improves the efficiency when the sample needs to be cooled during the test. The conical flask 2 can be rotated to a pretreatment position or a titration position, so that when the conical flask 2 needs to be switched between the pretreatment position and the titration position, the operator does not need to directly contact the conical flask 2, avoiding scalding the operator by the overheated conical flask 2, and the operation safety is relatively high.

[0042] In order to facilitate the lifting and rotation of the conical flask 2, the titration unit 5 includes a first support member 51, and the conical flask 2 is arranged on the first support member 51 in a liftable manner, and the conical flask 2 can be rotated around the first support member 51 to a pretreatment position or a titration position.

When the cross clamp 521 is clamped, the clamping member 52 can be fixed to the first support member 51. By loosening the cross clamp 521, the conical flask 2 can be rotated to the pretreatment position or the titration position according to the test requirements. In this embodiment, a fixing member is connected to the end of the clamping member 52 that clamps the conical flask 2, and the fixing member is used to clamp the conical flask 2.

[0045] The titration unit 5 further includes a second support member 53, a first stopper 54, a second stopper 55, a first reagent bottle 56, a second reagent bottle 57, a third reagent bottle 58, and a fourth reagent bottle 59. The first stopper 54 is disposed on the second support member 53 in a liftable manner and can be inserted into the mouth of the conical flask 2; the second stopper 55 is disposed on the second support member 53 in a liftable manner and can be inserted into the mouth of the conical flask 2; the first reagent bottle 56 and the second reagent bottle 57 can be communicated with the conical flask 2 through the first stopper 54; the third reagent bottle 58 and the fourth reagent bottle 59 can be communicated with the conical flask 2 through the second stopper 55; a first reagent is provided in the first reagent bottle 56, a second reagent is provided in the second reagent bottle 57, a third reagent is provided in the third reagent bottle 58, and a fourth reagent is provided in the fourth reagent bottle 59.

The two clamping members 52 are respectively used to connect the first plug body 54 and the second plug body 55. The specific structure of the two clamping members 52 on the second support member 53 is the same as that of the clamping member 52 on the first support member 51, and will not be elaborated here. When it is necessary to plug the first plug body 54 into the bottle mouth of the conical flask 2, loosen the clamping member 52 connected to the first plug body 54 and adjust the clamping member 52 to a suitable height; when it is necessary to plug the second plug body 55 into the bottle mouth of the conical flask 2, loosen the clamping member 52 connected to the second plug body 55 and adjust the clamping member 52 to a suitable height. The first reagent is 1,4-dioxane, which is a solvent for the epoxy resin sample to dissolve the sample; the second reagent is a metal base, which is a reagent that reacts with the epoxy resin sample; the third reagent is glacial acetic acid, which is used to consume the excess metal base in the conical flask 2; the fourth reagent is a silver nitrate solution, which is a titration reagent. To avoid the decomposition of silver nitrate upon exposure to light, the fourth reagent bottle 59 is a brown bottle. The epoxy resin saponifiable chlorine test equipment also includes several connecting pipes. Each reagent bottle is connected to the first plug body 54 or the second plug body 55 through each connecting pipe, and each connecting pipe passes through the first plug body 54 or the second plug body 55 so that each connecting pipe can connect each reagent bottle with the conical flask 2.

In this embodiment, the liquid supply pump 6 can accurately and quantitatively pump each reagent into the conical flask 2, making the test result error smaller. The setting of the liquid supply pump 6 makes the process of pumping each reagent into the conical flask 2 take less time and have higher efficiency. Moreover, by accurately and quantitatively pumping each reagent into the conical flask 2 through the liquid supply pump 6, the risk that each reagent is inhaled by the operator during the process of the operator dropping each reagent into the conical flask 2 with a dropper is reduced.

When the conical flask 2 rotates to the pretreatment position, the condenser 42 and the conical flask 2 are correspondingly arranged.

The fifth reagent is the solvent required for the sample and is used to dilute the sample. After stopping heating the sample, the fifth reagent is pumped through the condenser tube 42 into the conical flask 2, which can not only introduce the fifth reagent into the conical flask 2, but also wash the residual liquid sample in the condenser tube 42 into the conical flask 2.

[0050] Specifically, in order to facilitate the arrangement of the condenser tube 42 and the third plug body 43 on the third support member 41, in this embodiment, three clamping members 52 are provided on the third support member 41. One of the three clamping members 52 is used to connect the third plug body 43, and the other two are used to connect the condenser tube 42. The two clamping members 52 jointly support the condenser tube 42, so that the condenser tube 42 can be arranged on the third support member 41 more stably. The specific structure of the three clamping members 52 on the third support member 41 is the same as that of the clamping members 52 on the first support member 51, and will not be elaborated here. When it is necessary to pump the fifth reagent into the conical flask 2, loosen the clamping member 52 connected to the third plug body 43 and adjust the clamping member 52 to a suitable height so that the third plug body 43 can be plugged into the condenser tube 42. The fifth reagent bottle 44 is connected to the third plug body 43 through a connecting tube, and the connecting tube passes through the third plug body 43 so that the connecting tube can connect the fifth reagent bottle 44 to the conical flask 2 through the condenser tube 42.
