Abstract
The invention discloses a making formula of a rigid polyvinyl chloride plastic pipe for supplying water. The rigid polyvinyl chloride plastic pipe is prepared from 95.0-98.0 parts of polyvinyl chloride resin, 1.5-2.0 parts of tribasic aluminum sulfate, 0.7-0.9 part of dibasic lead phosphite, 0.4-0.6 part of aluminum stearate, 0.3-0.6 part of calcium stearate, 0.6-0.8 part of stearic acid and an adequate amount of carbon black. According to the making formula of the rigid polyvinyl chloride plastic pipe for supplying the water, the tribasic aluminum sulfate, the dibasic lead phosphite, the aluminum stearate, the calcium stearate, the stearic acid and the carbon black are added to the polyvinyl chloride resin; improvement of the performance of the rigid polyvinyl chloride plastic pipe is finally achieved, and the comprehensive performance of the rigid polyvinyl chloride plastic pipe for supplying the water is improved.
Description
Technical field
The present invention relates to plastics Application and preparation technical field, be specially a kind of water supply Vybak pipe and make formula.
Background technology
Pure polyvinyl chloride (PVC) resin belongs to the strong polar polymer of a class, and its Intermolecular Forces is comparatively large, thus result in PVC softening temperature and melt temperature higher, generally need 160 ~ 210 DEG C of ability processing.The replacement chloro contained in PVC molecule in addition easily causes polyvinyl chloride resin dehydrochlorination reaction, thus cause the DeR of PVC, so PVC is to thermoae instability, temperature rising can promote that PVC takes off HCL reaction greatly, pure PVC just starts de-HCL and reacts 120 DEG C time, thus result in PVC degraded.
PVC work in-process needs to add auxiliary agent, can obtain the goods such as various soft, hard, transparent, the electrical isolation meeting people's needs is good, foaming.When selecting kind and the consumption of auxiliary agent, the factor of each side must be considered comprehensively, as physics-chemical property, flowing property, processability, finally establish desirable formula.
But do not have a kind of plastic formula can realize making up PVC in prior art 120 DEG C time, just to start de-HCL react, cause the deficiency that PVC degrades, therefore designing a kind of novel plastic formula is people's technical issues that need to address.
Summary of the invention
A kind of water supply Vybak pipe is the object of the present invention is to provide to make formula, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: a kind of water supply Vybak pipe makes formula, it makes raw material and comprises polyvinyl chloride (PVC) RESINS, three basic aluminium sulphates, dibasic lead phosphite, aluminum stearate, calcium stearate, stearic acid and carbon black; Shared by described composition material, percentage number is: polyvinyl chloride (PVC) RESINS 95.0-98.0 part, three basic aluminium sulphate 1.5-2.0 parts, dibasic lead phosphite 0.7-0.9 part, aluminum stearate 0.4-0.6 part, calcium stearate 0.3-0.6 part, stearic acid 0.6-0.8 part and carbon black are appropriate.
As further technical scheme of the present invention: shared by described composition material, percentage number is: polyvinyl chloride (PVC) RESINS 96.0 parts, three basic aluminium sulphate 1.5 parts, dibasic lead phosphite 0.8 part, aluminum stearate 0.4 part, calcium stearate 0.4 part, stearic acid 0.7 part and appropriate carbon black.
Compared with prior art, the invention has the beneficial effects as follows: this water supply Vybak pipe makes formula, increases by three basic aluminium sulphates, dibasic lead phosphite, aluminum stearate, calcium stearate, stearic acid and carbon black in polyvinyl chloride (PVC) RESINS; Finally achieve the performance improving Vybak pipe, improve the over-all properties of water supply Vybak pipe.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention provides a kind of technical scheme: a kind of water supply Vybak pipe makes formula, it makes raw material and comprises polyvinyl chloride (PVC) RESINS, three basic aluminium sulphates, dibasic lead phosphite, aluminum stearate, calcium stearate, stearic acid and carbon black; Shared by described composition material, percentage number is: polyvinyl chloride (PVC) RESINS 95.0-98.0 part, three basic aluminium sulphate 1.5-2.0 parts, dibasic lead phosphite 0.7-0.9 part, aluminum stearate 0.4-0.6 part, calcium stearate 0.3-0.6 part, stearic acid 0.6-0.8 part and carbon black are appropriate.
embodiment one:
Select the water supply Vybak tube material of making 100 parts; Employing proportioning is
Polyvinyl chloride (PVC) RESINS 96.0 parts, three basic aluminium sulphate 1.5 parts, dibasic lead phosphite 0.8 part, aluminum stearate 0.4 part, calcium stearate 0.4 part, stearic acid 0.7 part and appropriate carbon black.
embodiment two:
Select the water supply Vybak tube material of making 100 parts; Employing proportioning is
Polyvinyl chloride (PVC) RESINS 96.0 parts, three basic aluminium sulphate 1.8 parts, dibasic lead phosphite 0.8 part, aluminum stearate 0.4 part, calcium stearate 0.3 part, stearic acid 0.6 part and appropriate carbon black.
embodiment three:
Select the water supply Vybak tube material of making 100 parts; Employing proportioning is
Polyvinyl chloride (PVC) RESINS 96.0 parts, three basic aluminium sulphate 1.7 parts, dibasic lead phosphite 0.8 part, aluminum stearate 0.4 part, calcium stearate 0.3 part, stearic acid 0.6 part and appropriate carbon black.
In the present invention:
Tribasic lead sulfate is mainly used as the stablizer of igelite, and thermal stability is excellent, has lasting stabilising effect.With dibasic lead stearate, barium stearate, calcium with there being lubrication; With dibasic lead phosphite and with there being synergy.
Dibasic lead phosphite is one of igelite thermo-stabilizer, because against sunshine, anti ageing property is better, is widely used in field, in the polrvinyl chloride product be exposed to the sun.
Lead stearate is used as thermo-stabilizer and the lubricant of polyvinyl chloride, and thermally-stabilised productivity ratio calcium stearate is large, and has good light stabilization concurrently.Be mainly used in the polrvinyl chloride product of various opaque hard.
Stearic acid is PVC heat stabilizer, has good oilness and good light, heat stabilization.In water supply hard polvinyl choride pipe, stearic acid contributes to " coking " that prevent in the course of processing, can defend cruelly to be placed in the caused finished films variable color of sulfide simultaneously.
