Abstract
The invention relates to a PVC protective sleeve for protecting a cable, which comprises a hollow sleeve body with a certain wall thickness, and a calcium-zinc composite stabilizer, stearic acid, chlorinated polyethylene and white oil are further added in raw materials of the body. The PVC protective sleeve for protecting the cable has light pipe weight, simple construction, low transportation and construction cost and a small amount of earth excavation, and can greatly shorten the construction period, and be lead-free and environment-friendly.
Description
Technical field
The present invention relates to a kind of PVC protective casing, especially a kind of PVC protective casing and production method thereof that is used to protect cable.
Background technology
Aerial cable goes underground, and has become one of target of countries in the world urban development.In the engineering construction that existing aerial cable goes underground, the mode that generally adopts asbestos to add pipe of cement is protected cable.But this traditional cable protection device is the very inconvenience because it from great, constructs on the one hand, improved the expense of transportation and construction, and earthwork excavated volume is big, has increased the construction period greatly; On the other hand, asbestos cause very serious pollution to environment, used in the world asbestos about 95% are chrysotile, its fiber can split into superfine first fiber, the diameter of unit's fiber is generally 0.5 micron, length can suspend several weeks, several months long in big G﹠W below 5 microns, pollutes constantly.Studies show that the disease relevant with asbestos is ubiquitous in multiple industrial occupation.When these tiny fibers are inhaled in the human body, will adhere to and be deposited on lung, cause PUD D, asbestos have been carcinogenic substance by IARC certainly.
Therefore, be necessary to design a kind of light weight, construction is simple and the cable protecting sleeve of environmental protection.
Summary of the invention
In order to overcome above defective, the technical problem to be solved in the present invention is: propose a kind of PVC protective casing and production method thereof that is used to protect cable.
The technical solution adopted in the present invention is: a kind of PVC protective casing that is used to protect cable; comprise hollow bushing body with certain wall thickness; it is characterized in that, also be added with calcium-zinc composite stabilizing agent, stearic acid, haloflex and white oil in the raw material of described body.
In a preferred embodiment of the present invention, the serviceability temperature of described PVC protective casing is between-30 ℃ to+105 ℃.
In a preferred embodiment of the present invention, described PVC protective casing is provided with the high-temperature resistant rubber circle in enlarging socket joint junction.
The invention still further relates to a kind of production method that is used to protect the PVC protective casing of cable, may further comprise the steps:
S1: will be processed into the PVC micelle after the PVC raw material high temperature melting;
S2: will be by the PVC micelle dried of step S1 acquisition;
S3: will be through the dried PVC micelle of step S2 by extruder heating and melting extrusion molding;
S4: cooling back baling,
Also be added with calcium-zinc composite stabilizing agent, stearic acid, haloflex and white oil in the described PVC raw material.
In a preferred embodiment of the present invention, the content of described each composition is divided into by quality:
PVC raw material 92.7
Calcium-zinc composite stabilizing agent 3.5
Stearic acid 0.5
Haloflex 3.0
White oil 0.3
In a preferred embodiment of the present invention, described PVC protective casing is widely used in electrical equipment, transformer, motor, lamp decoration, draws the external insulation protection of electric wire, electronic component, wire harness etc.
The invention has the beneficial effects as follows: the PVC protective casing of cable is protected in disclosed being used to; adopting PVC is that raw material has replaced traditional asbestos and adds pipe of cement; material is environmental protection more; and the pipe workpiece quality made from the PVC raw material is light; construction is simple; reduced the expense of transportation and construction, and earthwork excavated volume is little, has shortened the construction period greatly.Further; because at the raw material that are used for producing disclosed protective casing; nontoxic calcium-zinc composite stabilizing agent, stearic acid, haloflex and white oil have also been added; these stabilizers are all lead-free stabilizer, make disclosed PVC protective casing have unleaded advantage.
Description of drawings
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Among the figure: 1, body; 2, rubber ring.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
See also Fig. 1, the present invention has disclosed a kind of PVC protective casing that is used to protect cable, comprises the hollow bushing body 1 with certain wall thickness, also is added with calcium-zinc composite stabilizing agent, stearic acid, haloflex and white oil in the raw material of body 1.The serviceability temperature of disclosed protective casing is between-30 ℃ to+105 ℃.
In order to reach effective connection effect, disclosed PVC protective casing is provided with high-temperature resistant rubber circle 2 in enlarging socket joint junction, not only easy for installationly can also play the effect of expanding with heat and contract with cold of compensation tubing.
The present invention has also disclosed a kind of production method that is used to protect the PVC protective casing of cable, may further comprise the steps:
S1: will be processed into the PVC micelle after the PVC raw material high temperature melting;
