Abstract
The invention discloses a formula of a PVC (Poly Vinyl Chloride) double-wall corrugated pipe, and a production technology of the PVC (Poly Vinyl Chloride) double-wall corrugated pipe. The formula comprises the components as follows: PVC resin, calcium carbonate, chlorinated polyethylene, stabilizing agent, ACR resin, paraffin, polyethylene wax and stearic acid, wherein the components are in percentage by weights as follows: 60 to 72% of PVC resin, 18 to 30% of calcium carbonate, 5.4 to 7.2% of chlorinated polyethylene, 3.9 to 4.8% of stabilizing agent, 2.7 to 3% of ACR resin, 0.6 to 1.2% of paraffin, 1.2 to 2.4% of polyethylene wax, and 1.5 to 2.4% of stearic acid. The formula has the advantages that the PVC double-wall corrugated pipe is formed by extruding PVC resin which is served as the main raw material at high temperature and high pressure; the PVC double-wall corrugated pipe has resistance to impacting, resistance to high temperature and coldness, and has long service life, and is applied to paving underground communication pipelines, as well as performing protection to communication optical cables and cables.
Description
Technical field
The present invention relates to a kind of prescription and production technique of PVC double-wall corrugated pipe.
Background technology
The PVC double-wall corrugated pipe is used for the laying of underground communication pipeline, not shock resistance, and non-refractory, not cold-resistant, long service life is shorter, can not play a protective role to communications optical cable, cable.
Summary of the invention
Technical problem to be solved by this invention is: the prescription that the PVC double-wall corrugated pipe in a kind of work-ing life is provided.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: the prescription of PVC double-wall corrugated pipe; Comprise following component: polyvinyl chloride resin, lime carbonate, chlorinatedpolyethylene, stablizer, ACR resin, paraffin, polyethylene wax and Triple Pressed Stearic Acid, the weight percent of each component is: polyvinyl chloride resin 60%-72%, lime carbonate 18%-30%, chlorinatedpolyethylene 5.4%-7.2%, stablizer 3.9%-4.8%, ACR resin 2.7%-3%, paraffin 0.6%-1.2%, polyethylene wax 1.2%-2.4%, Triple Pressed Stearic Acid 1.5%-2.4%.
Further technical problem to be solved by this invention is: a kind of production technique of PVC double-wall corrugated pipe is provided, comprises the steps: above-mentioned raw materials is dropped into mixing machine according to weight percent, under 110 ℃ of-140 ℃ of temperature, mix; Automatically cool off after reaching requirement, after vibratory screening apparatus, automatic charging; Extrude through HTHP by twin screw extruder, after shaper is pulled out product, by the cutting machine fixed length cutting; Send into pipe-expanding machine, packing warehouse-in after enlarging is accomplished.
Advantage of the present invention is: above-mentioned PVC double-wall corrugated pipe, and employing polyvinyl chloride resin is main raw material, through the HTHP extrusion molding, shock resistance, high temperature resistant, cold-resistant, long service life is used for the laying of underground communication pipeline, and communications optical cable, cable are played a protective role.
