Abstract
The invention discloses a heat-resisting polyethylene tube for floor heating. The heat-resisting polyethylene tube for floor heating is characterized by being composed of the following raw materials in parts by weight: 86-90 parts of high density polyethylene, 2-3 parts of nepheline powder, 1-2 parts of aluminum dihydrogen phosphate, 1-2 parts of tall oil, 2-3 parts of tetradecanedioic acid, 2-3 parts of epoxy octyl stearate, 2-3 parts of carbon fibers, 2-3 parts of polytetrafluoroethylene wax, 0.1-0.3 part of calcium acetylacetonate, 0.7-1 part of absolute ethyl alcohol, 1-2 parts of ethylene bis stearamide and 6-9 parts of composite filler. The tubular product provided by the invention is good in heat resistance; and if the tubular product provided by the invention is applied to floor heating, the consumption of heating fuels can be greatly reduced and resources can be saved.
Description
Technical field
The present invention relates generally to a kind of tubing, relates in particular to a kind of floor heating heat-resisting polyethylene tube.
Background technology
Pvc pipe (UPVC pipe) hard polvinyl choride pipe, is to use pressure sintering extrusion molding after being coordinated with stablizer, lubricant etc. by polyvinyl chloride (PVC) RESINS, is the plastic pipe being developed and applied the earliest.UPVC pipe resistance to corrosion is strong, it is bonding to be easy to, price is low, quality is hard, but owing to having UPVC monomer and additive exudation, is only applicable in water feeding system that delivery temperature is no more than 45 ℃.Plastic conduit is for delivery of tap water, waste water, chemical, heating fluid and cooling fluid, food, ultrarapture liquid, mud, gas, the application of pressurized air and vacuum system.
PE pipe has medium-density polyethylene pipe and high density polyethylene pipe.The former is applicable to carry artificial coal gas, Sweet natural gas, the liquefied petroleum gas (LPG) of gaseous state, and the latter is mainly for delivery of Sweet natural gas.With steel pipe comparison, construction technology is simple, has certain snappiness, and main is to be not used as rotproofing, will save a large amount of operations.Shortcoming is with regard to apparatus not as steel pipe, and the special safe spacing of noting heating power heating in construction, and can not being exposed in air under sunlight, and responsive to chemical substance, prevents that the leakage of sewer line from damaging.
Summary of the invention
The object of the invention is just to provide a kind of floor heating heat-resisting polyethylene tube.
The present invention is achieved by the following technical solutions:
