Abstract

The invention discloses an integral glass fiber tape-reinforced electric hot melt tape and production equipment thereof. The integral glass fiber tape-reinforced electric hot melt tape comprises a hotmelt plastic layer, wherein a prepreg glass fiber-reinforced tape is fixedly connected between the hot melt plastic layer and a coated plastic layer; the hot melted plastic layer and the coated plastic layer form a plastic matrix; a heating steel mesh is fixedly connected between the prepreg glass fiber-reinforced tape and the hot melt plastic layer; and the prepreg glass fiber-reinforced tape, the heating steel mesh and the plastic matrix are fused into a stable integral structure to guarantee the strength of a welded plastic pipe. The integral glass fiber tape-reinforced electric hot melt tape is stable in structure, and simpler and more reliable in production process, and is used for connecting large-diameter plastic pipes. The production equipment of the integral glass fiber tape-reinforced electric hot melt tape is used for manufacturing the integral glass fiber tape-reinforced electric hot melt tape, and is suitable for the technical field of pipe connection.

Description

technical field [0001] The invention belongs to the technical field of pipe connection, and in particular relates to an integral glass fiber belt reinforced electric heating melting belt and production equipment thereof. Background technique [0002] With the continuous increase of the diameter of plastic pipes, the existing electrofusion sleeve connection technology and hot plate butt welding technology cannot meet the requirements of use. There are electric hot melt belts reinforced with steel mesh on the market, which are used for the connection of large-diameter plastic pipes. However, due to the lack of adhesion between steel and plastic, the separation of steel and plastic will occur after a long time. The step-by-step compounding process, so the separation between the heating net, the electric heating belt and the sealing plastic layer is easy to occur, which affects the quality of the product. Therefore, an electric heating belt with a more stable structure and a sim...
