As a result, the present inventor focused on the characteristics of hydrogel, which can be mixed with synthetic resin and molded, and is soluble in hot water, and mixed synthetic resin powder and hydrogel powder, and molded it. After that, it was immersed in water, hydrous alcohol, etc. and heated to elute the hydrogel, and it was discovered that the space formed by elution and removal becomes a complete through hole.Based on this knowledge, the present invention was completed. .

て使用できるので好都合である。 The synthetic resin used in the present invention may be a powder of commonly used polymer materials such as polyethylene, polypropylene, polystyrene, polymethyl methacrylate, polycarbonate, polyethylene terephthalate, polyacetal, etc. Most preferred is ultra-high molecular weight polyethylene, which has excellent wear and sliding properties. Furthermore, at present, the maximum molecular weight of ultra-high molecular weight polyethylene is approximately 6 million, and since such ultra-high molecular weight polyethylene is obtained in powder form in a reaction kiln, it can continue to be used as the synthetic resin of the present invention. It's convenient.

There are also hydrogels with high water absorption capacity that absorb water. For example, polyacrylates (Japanese Unexamined Patent Publication No. 53-46389) and hydrolyzed salts of starch/acrylonitrile graft polymers (J.

る。 Hydrogels used in the present invention include vinyl alcohol/acrylate copolymers, hydrolyzed salts of starch/acrylonitrile graft polymers, and polyacrylates, of which vinyl alcohol/acrylate copolymers are most preferred. . The reason for this is that the hydrogel is heat resistant within the molding temperature range (150-210℃), and when immersed in water, it swells to 500 times its own weight, and the pressure at the time of swelling causes the thin wall of the synthetic resin to swell. This is because it destroys pinholes, enlarges pinholes, and helps create complete through holes in synthetic resins.Furthermore, it is soluble in water at around 120°C, so it can be eluted from synthetic resins.

If the mixing ratio of vinyl alcohol/acrylate copolymer powder is less than 30% by weight, complete through holes cannot be formed, and if the mixing ratio of vinyl alcohol/acrylate copolymer powder is less than 30% by weight,
If it exceeds this, the strength of the final product will decrease, so it is desirable that the mixing ratio is as above.

This is because the boiling point of water needs to be raised in order to become soluble in water at 100°C.

す。）。 As is clear from FIGS. 1 and 2, the porous material produced by the above process is completely dissolved because the hydrogel is sufficiently eluted and only the synthetic resin remains, and the hydrogel swells sufficiently before being eluted. Through holes are drilled, and a block-like porous material can be obtained (Figures 1 and 2 are made by mixing 50% by weight of ultra-high molecular weight polyethylene (UHM-PE) and 50% by weight of hydrogel, (This shows the case of a porous material with a hydrogel eluted through a predetermined process.)
