本発明は硬化剤を混合して硬化させるレジンの
硬化時に表面に発生する泡の消去法に関するもの
で、その目的は真空ポンプ等を使用することなく
手軽に泡を消去する方法を得ることにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for eliminating bubbles generated on the surface of a resin that is cured by mixing a curing agent, and its purpose is to easily eliminate bubbles without using a vacuum pump or the like. It's about finding a way to do it.

等の欠点を有している。 Conventionally, standard samples for hardness tests, various specimens,
Waterproof electrical circuits, etc. are compounded with a transparent two-component resin. The purpose of this is to prevent breakage and deterioration of the compounded sample, make it easier to handle, and extend its lifespan.However, since it is a two-component resin, as shown in Figure 1, the hardening agent 1 is used as the base 2.
Air mixed in during stirring during mixing or air attached to the surface of the sample forms bubbles that rise through the resin during curing and collect on the surface. does not burst on the surface and remains as bubbles on the surface, and these bubbles make it difficult to see the compounded sample etc., even though the resin is transparent. As a method for eliminating bubbles on the surface of the resin and removing air bubbles in the resin, as shown in Fig. 2, a sample 4 is placed in a container 3, and a resin 5 is mixed with a hardening agent 1 and a base 2. is injected into the vacuum container 6 and cured while or after being evacuated by the vacuum pump 7. In this way, the air bubbles in the resin 5 are completely removed and no bubbles are generated on the surface of the resin 5, but it has the disadvantage that a vacuum container 6 and a vacuum pump 7 must be provided, making them expensive. There is.
本発明はこのような従来の欠点を解消すること
を目的としてなされたものでレジンの表面を油で
覆うことによつて容易に泡を消去する方法を提供
するものである。 The present invention has been made to overcome these conventional drawbacks, and provides a method for easily eliminating bubbles by coating the surface of the resin with oil.
第３図１，２に示す如く、容器３に試料４を入

注入し、該レジン５の表面を、該レジン５よりも
粘度が低い油８で覆い、その状態でレジン５を硬

を洗浄する。 As shown in FIGS. 1 and 2, a sample 4 is placed in a container 3, a resin 5 containing a hardening agent 1 and a base 2 is poured into the container, and the surface of the resin 5 is coated with an oil having a lower viscosity than that of the resin 5. 8 and harden the resin 5 in that state. After curing, the oil 8 is released and the surface of the resin 5 is washed.
以上の如く本発明によれば、高粘度のレジンで
覆われた気泡はレジンの層から油の層を介して空
気中へ放出されることによつてレジンの表面には
気泡すなわち泡は生じず、硬化後油を放出して洗
浄すれば、凹凸のないレジンの表面が得られ、試
料は透明のレジンを通してよく見える。 As described above, according to the present invention, air bubbles covered with high viscosity resin are released into the air from the resin layer through the oil layer, so that no air bubbles or bubbles are generated on the surface of the resin. After curing, the oil is released and washed, resulting in a smooth resin surface and the sample can be clearly seen through the transparent resin.
また、少数の試料に対するレジンのコンパウン
ドでも、真空ポンプや真空容器を設けることなく
安価で手軽に得られる等の実用的効果を奏するも
のである。 Furthermore, even resin compounds for a small number of samples can be obtained easily and inexpensively without the need for a vacuum pump or vacuum container, providing practical effects.
