Method for Molding a Pneumatic deck and resulting product

摘要

The present invention relates to a method for molding a pneumatic rubber cover, characterized by the steps of: A) providing an expandable, coated butyl rubber chamber; wherein the coating is a lubricating composition as the product of a mixture comprising i) about 20 to about 40 parts by weight of hydroxyl-capped polydimethylsiloxane characterized in that it has a viscosity within the range of about 12 million to about 28 million centistokes at 25 degrees C and ii) about 12 to about 20 parts by weight of at least one silane selected from a) a methyl hydrogen silane,characterized in that it has a viscosity within the range of about 20 to about 40 centistokes at 25 degrees C; and b) a dimethyl hydrogen silane characterized in that it has a viscosity within the range of about 80 to about 120 centistokes at 25 degrees C; B) provide a raw cover with elements that are to constitute its outer tread for ground contact purposes, two separate inextensible heels, side walls that extend radially outward from said heels to join the tread, a support frame with reinforcing elements and an inner surface of rubber latex material;(c) Insert the production deck into the cover mould printing plant, and install a curing chamber covering butilo in the production deck, and connect it with the internal part of the cover medium; (d) Close the mold of TA container and extend the curing chamber covered by internal hot liquid from the surface of latex material inside the deck, so as to press the liner of the container directly on the internal surface of the deck for pressing. (a) Shell under high temperature and pressure to form and volcano deck;(e) Open the mold on the deck, disinfect c'mara and remove the volcanic cover, usually in the form of cattle.
