Abstract
This invention discloses an environment protection type plastic protective sleeve for power cable which is made of chlorinated polyvinyl chloride, polyvinyl chloride, methacrylic acid-butadiene-styrene ternary polymerization resin, calcium carbonate and molybdate orange by mixing extruding powder raw material. Said invention has no heavy metal such as lead and tin bleeding duo to added with non-toxic and harmless calcium-zinc composite stabilizer, stearic acid, chlorinated polyethylene and white oil.
Description
Affiliated technical field
The present invention relates to installing of cable or electric wire with burying, belong to the power cable plastic protective casing especially.
Background technology
Aerial cable goes underground, and has become one of target of countries in the world urban development.But in the engineering construction that aerial cable goes underground; can find; using maximum cable protecting sleeves is to contain the cable plastics protective casing that heavy metal is particularly leaded and stabilizer tin is made; it as the patent No. 95111671.1 power cable plastic protecting casing; such sleeve pipe is embedded in the soil midium or long term and soaked into by underground water; lead wherein has separates out, thus near soil lead content value of being above standard causing.Investigation according to Shanghai Academy of Environmental Sciences shows that during the 1999-2000, lead tolerance exceeds 5-6 doubly than suburbs cleaning point in the test point topsoil of inner city, Shanghai City, is higher than due lead tolerance standard in the environment far away.
Summary of the invention
The purpose of this invention is to provide a kind of environment-friendly type power cable plastic protective casing, it is under the buried condition the particularly plumbous and tin of heavy metal free separates out, and production, installation personnel and soil is no longer increased the contamination hazard of lead and tin.
The present invention is achieved by the following technical solutions: the environment-friendly type power cable plastic protective casing; include chliorinated polyvinyl chloride, polyvinyl chloride, methacrylic acid-butadiene-styrene terpolymer resin, calcium carbonate, molybdate red; powder raw material mixed to extrude form; also be added with nontoxic calcium-zinc composite stabilizing agent, stearic acid, haloflex and white oil in it is characterized in that filling a prescription, the content of each composition is:
Chliorinated polyvinyl chloride 55.0 PHR (umber)
Polyvinyl chloride 45.0
Calcium-zinc composite stabilizing agent 3.5
Methacrylic acid-butadiene-styrene terpolymer resin 5.0-7.0
Stearic acid 0.5
Calcium carbonate 3.0
Haloflex 3.0
White oil 0.3
Molybdate red 1.2
Processing method of the present invention is to enter the pot of kneading after the powder raw material prescription is mixed to be heated to 105 ℃ ± 2 ℃, promptly enters volume then and is twice the above cold pot of kneading and mixes and stirs, and after sieve, enters the double screw extruder extrusion molding.
The present invention is owing to added additive and macromolecular compounds such as calcium-zinc composite stabilizing agent, stearic acid, haloflex and white oil in prescription; having abandoned as the patent No. is the leaded compound stabilizer that uses in 95111671.1 the power cable plastic protecting casing; make protective casing provided by the invention have unleaded, tin pollution, Vicat softening point still 〉=93 ℃, heat-resisting, high pressure resistant, advantage that mechanical performance reaches industry standard, meet the environmental requirement of upgrading urban and rural power grids.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Among Fig. 1, the wall thickness of present embodiment is 8.0 ± 0.3 millimeters, and density is 1450 ~ 1650kg/m
3, volume resistance 〉=1.0 * 10
13Ω cm, inwall coefficient of friction≤0.35.The sharp processing technology of this enforcement is be heated to 105 ℃ ± 2 ℃ after will the powder raw material prescription mixing, about 3 minutes of time, and promptly enter volume then and be twice the above cold pot of kneading and mix and stir, about 5 minutes of cold mixing time, send into the double screw extruder extrusion molding after sieving again.Sleeve pipe such as need enlarging, enlarging moulding on pipe-expanding machine at once.
