本発明は、ＧＬ工法に起因するカビの発生を押えること
を目的としたＧＬボンド調製法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a GL bond preparation method aimed at suppressing the growth of mold caused by the GL construction method.
ＧＬ工法は、コンクリート・コンクリートブロックに直

げられる。The GL method is a method of bonding plasterboard, etc. directly to concrete or concrete blocks using GL bond. The GL method is an excellent construction technique, but
There are also some drawbacks. A typical example of this is the growth of mold, and the following two mechanisms can be cited as the generation mechanism.
１、ＧＬボンドの乾燥が緩慢であるため、十分な乾燥状
態に至る前にカビが発生する。1. Because GL Bond dries slowly, mold grows before it reaches a sufficiently dry state.
２、ＧＬボンドの殆どがデンプン系であるため、季節変
化による水分吸収等により、容易にカビが発生する。2. Since most of GL Bond is starch-based, mold easily grows due to moisture absorption due to seasonal changes.
この問題を解決す“るために、現行では、１に関しては
、プラスターボード等に通気穴を設け、２に関しては、
殺カビ剤を混入する方法等がとられている。In order to solve this problem, currently, regarding 1, ventilation holes are provided in the plasterboard, etc., and regarding 2,
Methods such as mixing fungicides have been adopted.

い、その理由は、以下の２点に集約できる。[Problems to be solved by the present invention] The above methods for avoiding the growth of mold caused by the GL construction method are reasonably effective methods, but the reason is that they are not sufficiently effective. , can be summarized into the following two points.
１、 プラスターボード等に通気穴を設けても、ＧＬボ
ンド自身の水分蒸散率には限りが有る。1. Even if ventilation holes are provided in plasterboard, etc., there is a limit to the moisture transpiration rate of GL Bond itself.
２、混入される殺カビ剤に長期に渡る殺カビ効果を期待
することが難しい。2. It is difficult to expect a long-term fungicidal effect from the fungicide mixed in.
本発明が解決しようとするのは、以上の２点である。The present invention aims to solve the above two points.

出した。In order to increase the water evaporation rate of the GL bond itself, it would be sufficient to increase the porosity of the GL bond, but no approach from this point of view has been found in conventional products. As a result of various studies, the present inventors discovered that porous fine particles were used as a method to increase the water transpiration rate of GL bond itself.
It has been found that it is effective to mix it into L-bond.

間における変性の観点から問題が有った。In addition, if the purpose is to maintain the fungicidal effect over a long period of time to the fungicide mixed into GL Bond, it is easy to consider applying various microencapsulation technologies, but the current method is The prepared microcapsules are focused on coating the encapsulated drug, and when they are intended to be mixed into construction materials such as GL Bond, there are problems in terms of strength and deterioration over a long period of time.

It has been found that it is effective to mix GL bond with a substance attached thereto.
