Abstract
The invention discloses a polyethylene foam insulation tubular product and a continuous production method thereof. The method comprises that a polyethylene foam layer is extruded continuously and then is compounded on the external wall of a polyethylene water duct (3); a styrene thermoplastic elastomer layer is extruded and compounded on the polyethylene foam insulation layer (2) on the external surface of the polyethylene water duct (3); the polyethylene water duct (1), a middle polyethylene foam insulating layer (2) and the external thermoplastic elastomer protective layer (1) are compounded, foamed and coated. The insulation tubular product is primarily used for watering to solar water heaters, outdoor delivering tap water and being embedded in wall. The compounded tubular product produced in this method can overwhelm the problems of discontinuous extrusion, single product production and low production efficiency and realizes continuous production, thereby improving the production efficiency and solving the problems that the prior water duct is frozen easily in winter and is aged easily in summer.
Description
Technical field
The present invention relates to a kind of polyethylene foam rise thermal insulation delivery pipe and production method thereof, relate to a kind of conduit pipe, thermal insulation layer, protective layer used of comprising specifically in the polyethylene foam rise thermal insulation delivery pipe and the production method thereof of anti-freeze.This conduit pipe is applicable to that the continuous operation temperature is not higher than 90 ℃, and occasional peaks is not higher than 105 ℃, and working pressure is not higher than the medium of 2.5MPa.
Background technique
Existing water delivery tubing all be monomer structure, and heat insulating ability is poor when using winter, and therefore easy freezing need add the bag thermal insulation layer in use at the construction field (site), and not only construction complexity, and the thermal insulation layer of outsourcing easily seeps water, comes off causes thermal insulation property to weaken or loses.
Summary of the invention
For solving the technical problem that existing conduit pipe exists, the invention provides a kind of conduit pipe, thermal insulation layer, three layers of compound polyethylene foam rise thermal insulation delivery pipe of extruding of protective layer, and its quantity-produced method is provided.
For achieving the above object, the present invention adopts following design:
1, extruding continuously of polyethylene conduit pipe:
The polyethylene raw material adds in the polyethylene extruder drying hopper through automatical feeding system, after super-dry, extrudes through spiro rod plasticizing, and behind the die head Vacuum shaping, cooling is sent into foam extrusion die by tractor.
2, extruding continuously of polyethylene foam thermal insulation layer:
The polyethylene raw material adds in the polyethylene foam extruder drying hopper through automatical feeding system, after super-dry, through spiro rod plasticizing, is compound on the polyethylene conduit pipe outer wall through the die head foaming.The cooling rear haulage is sent into styrene analog thermoplastic elastomer and is coated extrusion die.
2, styrene analog thermoplastic elastomer is extruded continuously
Styrene analog thermoplastic elastomer, through spiro rod plasticizing, is compound on the polyethylene foam thermal insulation layer by overmold after the adding styrenic thermoplastic elastomer extruder drying through automatical feeding system.Scale cutting after cooling off.
The present invention has following good effect:
The technological deficiency that heat preservation construction complexity, the efficient that has solved conduit pipe effectively is low, thermal insulation property is unstable, working life is short.
