Description
Technical field
The present invention relates to a kind of joint sealant and preparation method thereof and process for filling colloid into, relate in particular to a kind of permanent-magnet machine with room temperature curing epoxy joint sealant and preparation method thereof and process for filling colloid into.
Background technology
The permanent magnetism of permanent magnet machine rotor is provided by the magnetic steel material that is inserted in the iron-core lamination slot.In the operational process of motor, the rotor high-speed rotation, loose magnet steel is subjected to displacement at internal rotor, has destroyed the transient equilibrium of rotor, and then directly has influence on the stable of motor.Fix through in the space of magnet steel and iron-core lamination, inserting joint sealant, can address this problem.
Environment for use in the permanent-magnet machine has higher requirement to the thermotolerance and the intensity of joint sealant, selects double-component epoxy resin embedding adhesive usually for use.Traditional double-component epoxy resin embedding adhesive is long set time, and solidification value is high, can not satisfy the needs of permanent magnet machine rotor process for filling colloid into.And there are two problems in the fast solidified joint sealant of most of room temperatures: one is that two component reaction are insufficient, makes that thermotolerance and the intensity after solidifying reduces greatly, has influenced the security and the stability of permanent-magnet machine; The 2nd, set time is short, and the corresponding operating time is also short.Because the space is very little between magnet steel and iron-core lamination, the encapsulating process need regular hour, too fast curing can influence the encapsulating operation.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of to satisfy the operating time that permanent-magnet machine uses long, room temperature fast-curing, and the double-component epoxy resin embedding adhesive high temperature resistant, that intensity is high.

Another technical problem to be solved by this invention is to provide the preparation method of above-mentioned double-component epoxy resin embedding adhesive to adopt following technical scheme
1), the preparation of Resins, epoxy A component comprises: will add 10 ~ 15 portions of reactive thinners in 100 parts of bisphenol A epoxide resins, add 5 ~ 10 parts of thixotropic agent then and in reaction kettle, stirred rotating speed 10 ~ 30rpm 5 ~ 10 minutes;
2), the preparation of solidifying agent B component comprises: with 15 ~ 25 parts of aliphatic amides, the mixed curing agent of 10 ~ 15 parts of modified aromatic amine and 5 ~ 10 parts of polyetheramines; Each component was stirred in reaction kettle 10 ~ 15 minutes, and rotating speed is that 100 rotating speeds are 100 ~ 200rpm200rpm.
A technical problem more to be solved by this invention is to provide above-mentioned double-component epoxy resin embedding adhesive
Process for filling colloid into is characterized in that comprising the steps:
1), the A component of said epoxy resin embedding adhesive packed into to be sealed in the plastic containers that have sharp mouth, solidifying agent B component is packed into to be sealed in the wide-mouth plastic containers;
2),, the pre-treatment of permanent magnet machine rotor before the encapsulating, is coated seal gum between preceding trim ring and preceding 10 ~ 15 iron-core laminations;
3), when encapsulating begins, one bottle of joint sealant B component is all poured in one bottle of A component, stirred 3 ~ 5 minutes, the blending ratio that mixes Resins, epoxy A component and solidifying agent B component is 3 ~ 4:1;
4), after encapsulating finishes, keep rotor vertically to place 1 ~ 2 hour, treat that joint sealant solidifies.
The operating time of step 3) said Resins, epoxy A component and solidifying agent B component is 20 ~ 40 minutes;
If temperature is lower than 18 ℃, can earlier the A component be placed 60 ℃ of baking oven preheatings to mix again in 5 minutes.
The present invention is through using aliphatic amide and modified aromatic amine with, and the solidifying agent operating time of gained can reach 20 ~ 40 minutes, and 1 ~ 2 hour set time, the joint sealant heat-resistance index after the curing is 158 ℃, and tensile strength is 45.3MPa.Contrast simple aliphatic amide curing system, mixing cured system of the present invention temperature within 20 minutes changes comparatively smooth in time, illustrates that the used mixing cured system of the present invention is longer than the independent aliphatic amide curing system operating time.In addition, because the adding of modified aromatic amine makes that curing system heatproof index is higher.
Because this room temperature curing epoxy joint sealant curing speed is fast; Gel time is short; Obviously heat release in the gelation process, when temperature variation the measurement of viscosity inaccurate, so also be one of content of this research through system temperature and the method for viscosity comprehensive characterization operating time and set time.When temperature sharply rose, system viscosity possibly descend to some extent, begin but solidify this moment, and temperature is too high also is inappropriate for the encapsulating operation, and be the operating time before this moment.
The invention has the beneficial effects as follows:
1, adopt aliphatic amide, modified aromatic amine mixed curing agent, heat-resistance index reaches 158 ℃ and reaches 45.3MPa with tensile strength, meets the requirement that is used for the permanent magnet machine rotor encapsulating;
2, through regulating each component ratio in the mixed curing agent, make the operating time reach 20 ~ 40 minutes, be 1 ~ 2 hour set time;
3, between preceding trim ring and preceding 10 ~ 15 iron-core laminations, coat seal gum, can avoid joint sealant under action of gravity, from the slit, to ooze out.
