Abstract
The invention provides a silicon-cored pipe production technology. The technology comprises the following steps: 1, selecting and proportioning 100 parts by weight of a special material for silicon-cored pipes, 40-60 parts by weight of high density polyethylene, 15-20 parts by weight of a metallocene modified master batch, 3.5 parts by weight of a black master batch and 4 parts of an antioxidant master batch; 2, synchronously extruding and compounding above materials through three extruders; 3, carrying out vacuum cooling shaping: cooling and shaping extruded and compounded pipes through a vacuum refrigerator and an immersion cooling water box; 4, carrying out meter counting printing to make the length of every silicon-cored pipe coil be 2000-3000m; and 5, pulling and reeling the silicon-cored pipe coil to obtain the finished silicon-cored pipes to be sold and used. The silicon-cored pipes produced through the technology have high tensile strength and good elongation at break, and can well meet market use demands.
Description
Technical field
The present invention relates to silicone pipes technical field, particularly a kind of silicone pipes production technique.
Background technology
Silicone pipes is the NEW TYPE OF COMPOSITE pipeline of a kind of inwall with silica gel matter solid lubricant, good seal performance, resistance to chemical attack, and construction costs is low, is widely used in motorway, the optical cable communications network system of railway etc.The silicone pipes generally used in the market is by silicon core pipe as special material, polyethylene raw material, colour batch, the blended processing of antioxygen masterbatch, its tensile strength, elongation at break are poor, often phenomenon of rupture is there is in construction process, and this pipe easily occurs entire volume phenomenon of rupture after for some time is placed in building site, service requirements cannot be met.
Summary of the invention
In order to overcome the defect of prior art, the invention provides following technical scheme:
A kind of silicone pipes production technique, described processing step is:
A) by weight, following material is selected to prepare burden: silicon core pipe as special material 100 parts, high density polyethylene(HDPE) 40 ~ 60 parts, metallocene modified masterbatch 15 ~ 20 parts, black master batch 3.5 parts, oxidation inhibitor master batch 4 parts;
B) after batching, by three synchronous extrusion claddings of forcing machine;
C) vacuum cooling sizing, carries out cooling and shaping by Vacuum refrigerator and immersion cooling water tank to the tubing after extrusion cladding;
D) metering prints, and the length of often coiling silicone pipes is 2000m ~ 3000m;
E) draw and batch, obtaining the finished product silicone pipes can selling use.
The beneficial effect that the present invention brings is: tensile strength is high, elongation at break good, can better meet market user demand.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A kind of silicone pipes production technique, described processing step is:
A) by weight, following material is selected to prepare burden: silicon core pipe as special material 100 parts, high density polyethylene(HDPE) 40 ~ 60 parts, metallocene modified masterbatch 15 ~ 20 parts, black master batch 3.5 parts, oxidation inhibitor master batch 4 parts;
B) after batching, by three synchronous extrusion claddings of forcing machine;
C) vacuum cooling sizing, carries out cooling and shaping by Vacuum refrigerator and immersion cooling water tank to the tubing after extrusion cladding;
D) metering prints, and the length of often coiling silicone pipes is 2000m ~ 3000m;
E) draw and batch, obtaining the finished product silicone pipes can selling use.
The advantage that technique of the present invention has is: the silicone pipes tensile strength that the process value adopted obtains is high, elongation at break good, can better meet market user demand.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
