れた。2. Description of the Related Art Conventionally, soft foams such as urethane foam and rubber foam have been used in cushion materials used for chairs and mats, etc. to provide a body pressure dispersing function. Since it absorbs body pressure only in one direction (pressurizing direction) and has a low effect of dispersing body pressure, the burden on the body of a person sitting for a long time such as a wheelchair user is unavoidable. It was Therefore, by using a soft gel-like substance, or by laminating urethanes with different resilience and different types of polymers, or by combining the gel-like substance with a soft foam, a cushioning material with better body pressure dispersibility can be obtained. was suggested.

面を汚すという問題もあった。The cushion material made of a gel-like substance containing water as a plasticizer has a drawback that the water content changes during use. On the other hand, the one using a gel-like substance using a non-aqueous liquid as a plasticizer has good flexibility, but lacks local stress dispersibility and is sufficient for the user to have a comfortable sitting comfort. However, it is inconvenient because it is heavy and not easy to carry. In addition, the gel-like substance using a non-aqueous liquid as a plasticizer has a problem that bleeding occurs when the plasticizer oozes to the surface depending on the type, and the contact surface is soiled.

る。In order to achieve the above-mentioned object, in the present invention, a gel-like material having both sol and gel characteristics, which contains a plasticizer between the molecular networks formed by crosslinking reaction of liquid polymer, is used. By laminating a substance and a low-repulsion foam material as a flexible foam, it imparts extremely high flexibility, shock / vibration relaxation property and stress dispersion property to the cushion material, and
Weight reduction can be achieved by filling the gel material with a polymer hollow body or polymer foam. Further, by sticking an elastomeric film on the surface of the gel-like substance, it is possible to prevent the gel-like substance from sticking and promote appropriate stress dispersion.

応力下での応力分散性が悪くなる。The amount of the cross-linking agent added is 0.4 to 0.8 equivalents per equivalent of the liquid polymer. If the amount is less than 0.4 equivalent, the crosslinking is insufficient and the crosslinked material easily flows out due to breakage of the outer covering material. On the other hand, when it exceeds 0.8 equivalent, the crosslinked material is sufficiently crosslinked and becomes hard, and the stress dispersibility under low stress is deteriorated.

Specifically, it is at least one selected from diisodecyl phthalate (molecular weight: 447) or diundecyl phthalate (molecular weight: 475). Bleed out easily occurs with a phthalic acid plasticizer having a smaller molecular weight than these, while A phthalic acid-based plasticizer having a large molecular weight has poor compatibility with the gel material, and the gel and the plasticizer are easily separated.

る。When the amount of the plasticizer added is 50 to 400 parts by weight, and less than 50 parts by weight, based on 100 parts by weight of the liquid polymer, the hardness of the gel material becomes high and sufficient stress dispersibility cannot be obtained. However, there is a problem that the deformation recovery is slow when the stress is removed. If it exceeds 400 parts by weight, the plasticizer cannot be retained in the gel material and the gel and the plasticizer are easily separated, and the bleed is more bleeding than the skin material. It's easier to get out.

分散性が発揮できない。The particle diameter of the polymer hollow body or polymer foam is 2 mm or less, preferably 0.5 mm or less. If the particle size exceeds 2 mm, the polymer hollow body or polymer foam will separate from the liquid polymer, plasticizer, etc., and will not be a homogeneous gel material, and the flexibility will be lost, and sufficient stress dispersion capability will be achieved. And vibration,
Impact relaxation cannot be exhibited. The volume fraction of the amount of the polymer hollow body or polymer foam added is 10 to 80%. If the volume fraction is less than 10%, a sufficient weight-reducing effect cannot be obtained, while if it exceeds 80%, the hardness becomes too high, the elongation of the gel material becomes small, and the recovery property against deformation also decreases. Therefore, sufficient vibration, shock relaxation and stress dispersibility cannot be exhibited.
