Construction of gliding board and method of production

Abstract

A gilding board, which means of the kinds of sporting or leisure boards for sliding on waters, snow and land, was constructed by polyethylene foam material, in three-ply or above layers of constant density or different densities as its multi-layer of bard core, agglutinate with a layer of plastic polymer graphic film on one side of the board core and bonded with high tenacity of plastic protective board on the other side. The essence of the gliding board is its particular methodology of production by mechanically adhibiting instant injection of high temperature of compound thermoplastic substance on the surface of the first layer of the board core while bonding with a layer of plastic graphic film. Thereafter, cleaving a plastic protective board or polyethylene foaming skin with the third layer of board core, by adopting heat lamination method to viscose the second layer of board core with both graphic film layer plus plastic protective board layer, in which an outer core of media foam layer is being exempted between the graphic film layer and board core, and the plastic polymer protective board to board core, as a result of simplify the production process in making the board, less resources and material to be consumed during the production that leads environmental-friendly, reducing cost to be involved in production, but provides a great performance and substantially deep-set of the structure of the board. Three-ply board core enhances the greater crash-worthiness from water surfing, snow or land gliding, with provision of better comfort and a function of high security for users by smooth surface of board on both ends.
