Title:
SHOCK-ABSORBING MEMBER, SHOCK-ABSORBING MEMBER FOR AUTOMATIC MOVEMENT DEVICE FOR PAINTING, AUTOMATIC MOVEMENT DEVICE WITH SHOCK-ABSORBING MEMBER, AND AUTOMATIC MOVEMENT DEVICE FOR PAINTING WITH SHOCK-ABSORBING MEMBER
Document Type and Number:
WIPO Patent Application WO/2017/038910
Kind Code:
A1
Abstract:
A shock-absorbing member comprises a polyurethane foam body with a skin, the polyurethane foam body with a skin being provided with a foam layer and a skin layer formed on the surface of the foam layer. The polyurethane foam body with a skin contains essentially no silicon compounds. The foam layer is a polyurethane foam body obtained by reacting an isocyanate foam component and an active-hydrogen-group-containing foam component. The skin layer is a polyurethane resin layer obtained by reacting an isocyanate skin component including an aliphatic polyisocyanate and/or an alicyclic polyisocyanate with an active-hydrogen-group-containing skin component. The storage elastic modulus (E'coat) of the skin layer at 23°C is 1×107 Pa to 3×108 Pa. The storage elastic modulus (E'foam) of the foam layer at 23°C is 1×105 Pa to 5×106 Pa. The ratio (E'coat/E'foam) of the storage elastic modulus (E'coat) of the skin layer at 23°C to the storage elastic modulus (E'foam) of the foam layer at 23°C is 10-500.
