Body with surface structure improving friction performance

摘要

The body (14) such as wind screen wiper or elastic sealing comprises an elastomer material or an external elastomer layer, where a surface structure (1) improving the friction behavior is formed in an area of the body in the surface of the elastomer body or in the external elastomer layer of the body. The surface structure comprises elevations (11) that are prismatic, pyramid-stump shaped, cylindrical, cone-shaped or gill-shaped form and are distanced from one another through a channel (12). The abutting face of the elevations stretches a joint plain. The body (14) such as wind screen wiper or elastic sealing comprises an elastomer material or an external elastomer layer, where a surface structure (1) improving the friction behavior is formed in an area of the body in the surface of the elastomer body or in the external elastomer layer of the body. The surface structure comprises elevations (11) that are prismatic, pyramid-stump shaped, cylindrical, cone-shaped or gill-shaped form and are distanced from one another through a channel (12). The abutting face of the elevations stretches a joint plain. The maximum surface extent of the abutting face of the elevations is 100 nm to 5 mm. The maximum dimension of the abutting face of the elevations is less than 300 mu m. The abutting faces of the elevations of the surface structure are uniformly formed and the form possesses a square, isosceles triangle, regular hexagon or polygon. The elevations are arranged in hierarchic plain and have rectangular, trapezoidal or gill-shaped longitudinal sections. The height of the elevations is 1-100% of the maximum dimension of the abutting face of the respective elevations. The surface portion of the abutting face of the elevation on the total area of the abutting face of the elevation and the channel is 20-99%. The channel comprises a hexagonal, rectangular, triangular, trapezoidal or polygonal cross-section. The channel has a circular or elliptical cross-section. The body is a transfer film or laminating film.
