Abstract
The invention relates to a heat-resistant PVC (Polyvinyl Chloride) pipe, which is made from the following basic materials in part by weight: 60 parts of PVC resin, 40 parts of SAN (Styrene-Acrylonitrile) resin, 3-6 parts of stabilizing agents, 1-2 parts of lubricant, 2-4 parts of titanium white and 8-15 parts of light calcium. The heat-resistant PVC pipe has the advantages that: the heat resistance of the PVC pipe is improved, and the heat-resistant PVC pipe can safely exhaust or convey liquid or gas with the temperature below 70 DEG C for a long time.
Description
Technical field
The present invention relates to a kind of plastic conduit, particularly a kind of heat-resistant polyvinyl chloride pipeline.
Background technology
As everyone knows, general conveying of polyvinyl chloride pipeline and exhaust temperature are no more than 45 ℃ liquid or gas, and the too high life-time service of temperature can make pipeline lose the physicals that it should have, and causes pipeline work-ing life and safety performance to descend.
Summary of the invention
The objective of the invention is to address the above problem, carry liquid or gas heat-resistant polyvinyl chloride pipeline below 70 ℃ but propose a kind of long-term safety.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is such.The heat-resistant polyvinyl chloride pipeline is made up of the basic material of weight part, 60 parts of PVC RESINSs, 40 parts of SAN resins, stablizer 3～6,1～2 part of lubricant, 2～4 parts of white titanium pigments, 8～15 parts of fine particle calcium carbonates.
Advantage of the present invention is: improve the resistance toheat of polyvinyl chloride pipeline, but liquid or the gas below 70 degrees centigrade is discharged or carried to long-term safety.
Specific embodiments
Each basic weight of material part of a kind of heat-resistant polyvinyl chloride pipeline is: 60 parts of PVC RESINSs, 40 parts of SAN resins, 4.5 parts of stablizers, 1.2 parts of lubricants, 2.5 parts of white titanium pigments, 12 parts of fine particle calcium carbonates.
Heat-resistant polyvinyl chloride pipeline preparation technology of the present invention is undertaken by following operation:
A) by weight,, mix, and in this TR, keep more than 10 minutes at 90～120 ℃ with PVC RESINS, SAN resin, stablizer, lubricant, white titanium pigment and fine particle calcium carbonate;
B) said mixture is put into cold mixer and be cooled to 25～45 ℃, import dry feed bin;
C) compound in the dry feed bin is extruded, processed tubing behind vacuum sizing and the cooling forming through the awl twin screw extruder;
D) fixed length cutting, enlarging, packing.
Heat-resistant polyvinyl chloride pipeline of the present invention has adopted the very outstanding SAN resin of resistance toheat; As everyone knows; The SAN resin is usually used in making plastic lighter; Vicat softening temperature surpasses 105 degrees centigrade, can improve the resistance toheat of polyvinyl chloride pipeline greatly, but liquid or the gas below 70 degrees centigrade is discharged or carried to heat-resistant polyvinyl chloride pipeline long-term safety.
What particularly point out is, specific embodiments is the more representational example of the present invention, and obvious technical scheme of the present invention is not limited to such scheme, and a lot of forms can also be arranged.Present technique field personnel all should think invention which is intended to be protected with disclosed mention or technical scheme that it is associated among the present invention.
