Abstract
The invention discloses a thermoplastic flame-retardant plastic pipe prepared from the following raw materials in parts by weight: 70-100 parts of polytetrafluoroethylene, 5-12 parts of a flame retardant, 5-15 parts of epoxy resin, 1-5 parts of dibutyl phthalate, 0.5-3 parts of carbon fibers, 3-8 parts of carbon black and 2-10 parts of stearic acid, wherein the flame retardant is a mixture of antimony trioxide and zinc borate. Compared with a common thermoplastic flame-retardant plastic pipe, the mechanical properties of tensile strength, impact resistance and the like of the plastic pipe disclosed by the invention are obviously improved.
Description
Technical field
The present invention relates to plastics tubing technical field, especially a kind of Thermoplastic fire retardant plastic pipe.
Background technology
Can melt after thermoplastics refers to heating, mold cools down aftershaping can be flowed to, the plastics that can melt again after reheating; Can use heating and cooling, making it produce reversible change, is so-called physical change.Its continuous print use temperature of general thermoplastics below 100 DEG C, polyethylene, polyvinyl chloride, polypropylene, polystyrene be called four large general-purpose plastics.Thermoplastics has excellent electrical insulating property, and thermoplastics is easy to forming process, but thermotolerance is lower, easy firing, and combustionvelocity is fast, can produce a large amount of toxic gas.According to statistics, in fire because to suffocate and the loss of life and personal injury that causes of smoke poisoning accounts for 50 ~ 80% of the total casualties of fire.In recent years, the fast development of electronic apparatus, building, aviation and automobile industry higher requirement that the performance of plastics is proposed.But the plastics of flame retardant type are nonflammable, rate of flame propagation is little, mass loss rate and heat release rate lower, and there is certain self-extinguishing.
The Thermoplastic fire retardant plastic performance of current use can not meet the demands, and adopts halogen flame more, and combustion processes can be released hydrogen halide and be caused serious harm to human body.
Summary of the invention
The object of this invention is to provide a kind of Thermoplastic fire retardant plastic pipe, this Thermoplastic fire retardant plastic pipe can solve the problem of existing thermoplast flame retardant plastics flame retardant properties difference.
In order to solve the problem, the technical solution used in the present invention is:
Thermoplastic fire retardant plastic pipe of the present invention, it is characterized in that being prepared from by the raw material of following parts by weight: tetrafluoroethylene 70 parts ~ 100 parts, fire retardant 5 parts ~ 12 parts, epoxy resin 5 parts ~ 15 parts, dibutyl phthalate 1 part ~ 5 parts, 0.5 part ~ 3 parts, carbon fiber, carbon black 3 parts ~ 8 parts, stearic acid 2 parts ~ 10 parts; Wherein said fire retardant is the mixture of antimonous oxide and zinc borate.
In technique scheme, scheme can also be more specifically:
Described Thermoplastic fire retardant plastic tube preparation method is:
A, proceed in reactor by tetrafluoroethylene and epoxy resin, adjustment rotating speed, at 300 revs/min ~ 500 revs/min, mixes;
B, add fire retardant, epoxy resin, dibutyl phthalate, carbon fiber, carbon black and stearic acid, adjustment screw speed is 120 revs/min ~ 180 revs/min, and control temperature is 190 DEG C ~ 200 DEG C, melt extrudes, proceeds to mould, extrusion molding.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
Thermoplastic fire retardant plastic pipe of the present invention take tetrafluoroethylene as base material, add epoxy resin, dibutyl phthalate, carbon fiber, carbon black and stearic acid, and using the mixture of antimonous oxide and zinc borate as fire retardant, its product flame retardant effect is remarkable, during burning, the amount of being fuming is few, environmental pollution is less, and the mechanical properties such as the tensile strength of prepared plastics tubing, impact resistance are significantly improved compared with common thermoplastic's flame retardant plastics pipe.
