Abstract
A pipe for passing electric line through it is prepared from PVC as basic resin, stabilizer, activated light calcium carbonate (CaCO3) as filler, plasticizer, lubricant and modifier through heating, stirring and extruding out.
Description
The invention belongs to process for preparing polyvinyl chloride pipe filled by light calcium carbonate and used for passing line through it.
The weighting agent that common high filling polyvinyl chloride (PVC) is adopted is a calcium carbonate superfine powder, after being filled into it among 100 parts the PVC with 20-30 part, the performance of high filled PVC tubing can meet application requiring, and the patent of the high filled PVC of calcium carbonate superfine powder is a lot of at home and abroad, and has obtained application.Introduced the lime carbonate that applies particle diameter 1-5 μ m with maleic anhydride graft copolymer as RUSSP SY1497193, and formed ionic bonding, will obviously improve the performance of product after itself and the PVC blend on the lime carbonate surface.Yet surface treated light calcium carbonate yet there are no report with the high filled PVC threading of the amount tubing of 20-30 part.
The purpose of this invention is to provide a kind of process for preparing polyvinyl chloride pipe filled by light calcium carbonate and used for passing line through it, the matrix resin PVC that this method is selected is loose type, and adding stablizer, weighting agent are activation light calcium carbonate (CaCO
3), softening agent, lubricant, properties-correcting agent, through heating, stir, be extruded into pipe.
The present invention adopts the filling surface treatment technology, with light calcium carbonate (CaCO
3) activate, a part of group in the activator molecule can react with the chemical group of inorganic filler surface, form firm chemical bond, another part has the group of close organism performance, then can or twine with reactive organic molecule, the material that two kinds of polarity are differed widely combines securely, reaches the purpose that improves high filled PVC mechanical properties of tubular goods.The CaCO of activated processing
3Weight that can 20-30 part is filled in 100 parts the polyvinyl chloride resin, and the mechanical property of its made high filled PVC penetration pipe greatly reduces the cost of PVC penetration pipe with close with the performance of the high filled PVC pipe of amount calcium carbonate superfine powder.
Matrix resin PVC of the present invention is loose type, and proportion is (weight percent, down together) 65-70% in batching; Stablizer is a lead sulfate tribasic, dibasic lead phosphite and dibutyl tin laurate, and proportion is at 1.5-5%; Weighting agent is activation light calcium carbonate (CaCO
3), proportion is 13-20%; Softening agent phosphorus benzene bis-acid potassium dibutylester (DOP), triphenyl phosphite proportion are 0.4-0.5%; Lubricant stearic acid, calcium stearate, lead stearate, illiteracy dawn cured (E wax), paraffin, polyethylene proportions such as (PE waxes) are 0.5-1.5%; Properties-correcting agent chlorinatedpolyethylene (CPE), acrylic resin (ACR) proportion are 5-16%.Equipment used is high speed kneader, single screw extrusion machine, tractor, its processing sequence is for will being stirred to 40 ℃ in PVC and the stablizer adding kneader earlier, add softening agent, be stirred to 60 ℃, add weighting agent again, lubricant stirs to 100 ℃-110 ℃, be cooled to 60 ℃ of dischargings, continue to be cooled to 40 ℃ after, can send into single screw extrusion machine and be extruded into pipe in 140 ℃-180 ℃.
The present invention has scientifically adopted filling surface activation treatment technology, rational allocation each component proportioning, make full use of the conspiracy relation between each component, develop a kind of processing that is easy to, be convenient to the high light filling lime carbonate polychloroethylene pipes of powder time processing moulding, propose first and realized the activation light calcium carbonate weighting agent that a kind of cost is low, loading level is high, performance is good, substituted the high calcium carbonate superfine powder of price.
