Description

【発明の詳細な説明】 本発明は水素吸蔵合金成形体、更に詳細には合成樹脂を
バインダーとして用いた水素吸蔵合金の粉末を含む水素
吸蔵合金成形体に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hydrogen storage alloy molded article, and more particularly to a hydrogen storage alloy molded article containing powder of a hydrogen storage alloy using a synthetic resin as a binder.

従来より、水素吸蔵合金として、たとえばランタン−ニ

た。Conventionally, various alloys such as lanthanum-nickel type, titanium-iron type, zirconia-manganese type, titanium-cobalt type, and Mitsushi metal type are known as hydrogen storage alloys. As the hydrogen is gradually pulverized during repeated desorption, the alloy powder is scattered, and when heating the tank for hydrogen desorption, the thermal conductivity is poor and extra heat must be applied.

本発明は微粉化することが々く、熱伝導性の良好な水素
吸蔵合金成形体を提供することを目的とする。An object of the present invention is to provide a hydrogen storage alloy molded article that is often pulverized and has good thermal conductivity.

~97% by weight, and 15~3% by weight of a synthetic resin having a softening point higher than the heating temperature at which hydrogen occluded in the alloy is released.

以下、本発明につき更に詳細に説明する。The present invention will be explained in more detail below.

ｅＴｉ−Ｈ−５ＬａＮｉ　５−Ｈ。A hydrogen storage alloy that can be processed into a molded article according to the present invention must be one that releases hydrogen at a Y crystallinity lower than the softening point of the synthetic resin. Therefore, a metal-hydrogen gas having a phase equilibrium temperature of 150 DEG C. or less at a pressure of 50 to 0.1 atm, preferably 100 DEG C. or less at a pressure of 20 to 1 atm is used. Examples of these are MmNi 5-H, F
eTi-H-5LaNi5-H.

For Ni 5-XMnX, the temperature within the above pressure range is practically preferable. According to the invention, these hydrogen storage alloys are used in powder form. Although the powder degree is not particularly critical, it is preferable to set it to 10 mesh or less because it enables uniform dispersion in the molded article of the present invention.

望ましい。The synthetic resin that can be used in the molded article of the present invention is a synthetic resin that has a softening point higher than the heating temperature for releasing hydrogen stored in the hydrogen storage alloy, preferably 100° C. or higher. These synthetic resins include phenolic resin,
I>g Thermosetting resins such as base resins, melamine resins, unsaturated polyester resins, Evoquin resins, furan resins, Nuricon resins, butone resins, polyurethane, and gy/lene resins, as well as cellophane, collodion, polypropylene, polybutadiene, polyethylene, polyvinyl Thermoplastic resins such as butyral, polystyrene, and celluloid can be mentioned. Among these, polyurethane, cellophane, collodion, polystyrene, and polypropylene are preferred because they have a high softening temperature and good H2 gas permeability. These synthetic resins are in powder form. The fineness is not particularly critical, but in consideration of dispersibility, it is desirable to set it to 10 mesh or less.

It can also be included. If the content is less than 2 parts by weight, the thermal conductivity will not be improved, while if it exceeds 8 parts by weight, the hydrogen storage capacity will decrease.

If the hydrogen storage alloy is less than 85% by weight, the hydrogen storage capacity will decrease, while if the synthetic resin is less than 3 parts by weight, the strength of the molded body will be insufficient. In producing the molded body of the present invention, hydrogen storage alloy powder, synthetic resin powder, and optionally copper powder are thoroughly mixed, placed in a mold, heated to a temperature equal to or higher than the melting point of the synthetic resin, and then cooled.
