ている。Since the rotating body of the rotor for rotating electric machines has a large diameter,
If it is not perfectly balanced, vibration will occur during rotation. Conventionally, in many cases, the outer diameter of the rotating body was cut in order to maintain balance. However, since Jin's method generates noise during rotation, other methods have been used to balance the rotation by embedding lead-covered lead.

As a result of research to obtain a resin composition with low viscosity, no sagging, and excellent storage stability, we developed a system containing an epoxy resin, a latent hardener, and an inorganic filler. We have investigated the use of chicken-adding agents, etc., which have good storage stability, a pit life of over 6 months at room temperature, low viscosity, high thixotropy, and quick curing. The present invention has led to the provision of a one-component liquid epoxy resin composition that can be discharged by a machine.

常に多岐にわたっているが、本発明の目的とする組成物
を得るためKは、チキン性付与効果が高く、増粘作用が
低く、高温時の重量減少率が低いものが望ましい。There are a wide variety of chicken imparting agents, including organic compounds and inorganic compounds, but in order to obtain the composition targeted by the present invention, K has a high chicken characteristic imparting effect, a low thickening effect, and a high temperature resistance. It is desirable that the weight loss rate is low.
従って、溶剤等を使用しているチキン付与剤は使えない

キン性の経時変化が大きく本発明には不適である。Therefore, chicken imparting agents that use solvents etc. cannot be used. Colloidal silica is the best inorganic chicken-imparting agent, but it is unsuitable for the present invention because it lacks chicken properties at high temperatures and the chicken properties of the composition change significantly over time.

モンモリロナイトをいう。Possible organic chicken-imparting agents include polyethylene oxide, polyamide, pendinylidene sorbitol, and an organic composite of colloidal hydrous aluminum silicate (Olman). Oxidation, f IJ ethylene, polyamide, etc. are unsuitable for use in the present invention because they undergo thermal deterioration at high temperatures (120 to 200°C). As the chicken imparting agent of the present invention, organic composites of colloidal hydrous aluminum silicate and organic bentonite that do not lose their chicken properties at high temperatures, are heat resistant, and have little change in chicken properties over time are suitable. . As a result of repeated studies to obtain a composition with low viscosity, it was confirmed that organic bentonite is optimal. In the present invention, organic bentonite refers to montmorillonite surface-modified with an organic compound.
以上の結果よシ、チキン付与剤として有機ベントナイト

への適用が困難になる。As a result, if the amount of organic bentonite is less than 8 parts per 100 parts of epoxy resin, sagging occurs during curing, so it is necessary to add 8 parts or more. Also, the amount added is 1
If the amount is 2 parts or more, it becomes extremely viscous (4,000p).
oise / 25°C or higher), workability becomes difficult, especially application to automatic machines.
このため有機ベントナイトの添加量としては、エポキシ
樹脂100部に対して8部から12部が最適である。Therefore, the optimum amount of organic bentonite to be added is 8 to 12 parts per 100 parts of the epoxy resin.

自動化が可能になり、生産性が向上する。rotate? Conventionally, in order to correct the unbalance during rotation of the rotating body of the loading rotor, a highly viscous material in the shape of an F-shaped material was used to manually apply the sound. If a liquid Eixy resin composition is used, it has excellent storage stability, so there is no risk of mixing the main ingredient or curing agent when using it, unlike in the case of two-component products, and it can be dispensed metered using an automatic dispensing machine. Because it is thin and hardens quickly, it is possible to automate balance correction, improving productivity.

硬化時にタレ落ちが生じない。In addition, if organic bentonite is used as the chicken-imparting agent in the one-component liquid edexy resin composition of the present invention, the thickening effect at around room temperature is small, so the workability when using an automatic dispensing machine is excellent. It does not lose its chicken properties even when heated and does not drip off during heat curing.
