Description
Technical field
The invention belongs to plastic products art field, more particularly to a kind of preparation method of thermal diffusivity modified plastic pipe.
Background technology
Plastic tube is usually to be raw material, added stabilizer, lubricant, plasticizer etc. with synthetic resin, that is, polyester, with
The method of " modeling " forms in tuber through extrusion process.Due to it have light, corrosion-resistant, good appearance, without bad smell,
Handling ease, it is easy for construction the features such as, more and more extensive application is obtained in architectural engineering.Although plastic tube has above-mentioned
Advantage, but its still there is the shortcomings that heat dispersion and bad tensile property, it is necessary to be constantly improved to plastic tube.
The content of the invention
The present invention provides a kind of preparation method of thermal diffusivity modified plastic pipe, and plastic tube made from this method has good
Heat dispersion and tensile property.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：90 parts of polypropylene, 20 parts of polyolefin
~25 parts, 8 parts~12 parts of polyethylene octene elastomer, 5 parts~7 parts of low lead compound stabilizer, titanium dioxide 5 parts~7
50 parts~60 parts of part, 1 part~3 parts of stearic acid and carborundum；Its preparation method comprises the following steps：
A. above-mentioned parts by weight are pressed, first by polypropylene and polyolefin heating melting, and are stirred；
B. after B steps terminate, polyethylene octene elastomer, low lead compound stabilizer, titanium dioxide and hard are added thereto
Resin acid, stir, be then warming up to 160 DEG C~165 DEG C again, insulation reaction 3 hours；
C. after B step reactions terminate, 120 DEG C~125 DEG C are first cooled to, then adds carborundum thereto, insulated and stirred 0.5
Hour；
D. after the stirring of C steps terminates, it is put into mould, extrusion forming.
In above-mentioned technical proposal, more specifically technical scheme is：90 parts of polypropylene, 25 parts of polyolefin, polyethylene octene are total to
50 parts of 8 parts of elastomer, 6 parts of low lead compound stabilizer, 7 parts of titanium dioxide, 3 parts of stearic acid and carborundum；Further,
80 parts of polypropylene, 20 parts of polyolefin, 6 parts of polyethylene octene elastomer, 5 parts of low lead compound stabilizer, 5 parts of titanium dioxide,
