WIPO Patent Application WO/2016/112623

A1

A compound type polyurethane toilet seat, comprising a surface coating layer (1), a positioning structure and a seat support (2). The surface coating layer (1) is made from polyurethane and seamlessly covers the outer surface of the seat support (2) by means of the positioning structure. The preparation process comprises: step 1, spraying a release agent and an in-mold paint in a cavity of a mold (3); step 2, cleaning the surface of the seat support (2); step 3, polishing or abrasive blasting; step 4, thermally treating the seat support (2); step 5, spraying the release agent in the cavity of the mold (3), and installing the seat support (2) in the cavity of the mold (3); step 6, injecting a polyurethane raw material into the cavity of the mold (3), and shaking the mold; step 7, foaming the polyurethane raw material; and step 8, opening the mold to take out the product after the polyurethane is cured in the mold (3), thereby completing the whole preparation process of the product. The polyurethane toilet seat employs one-time composite molding, the machining process is optimized, the use cost is reduced, the bonding intensity of the product is increased, and the use quality of the product is improved.
