Description
Technical field
The present invention relates to PVC water pipe technical field, particularly relate to a kind of Environmental Super-fine fully vulcanized powder rubber polrvinyl chloride
Composite water pipe and preparation method thereof.
Background technology
Pressure feed water plastic pipe should have high intensity and high tenacity simultaneously.RPVC (PVC-U) feed pipe
Material toughness is not enough, easy booster under the effect of external condition, and the mechanical property improving PVC-U material is to improve product to use the longevity
The effective way of life." the ultra-fine fully vulcanized powder rubber study on the modification to RPVC " literary composition actual is asked for this
Topic, from toughness reinforcing, the basic ideas of Reinforced PVC-U material property, uses high model resin extruded PVC-U feed pipe first
Material, uses full sulfuration ultra fine powder rubber blending and modifying PVC-U material first, has inquired into micro-cross-linking agent chemical modification PVC-U material
The effect of material.By test PVC-U system mechanical property, observe blending modification system microstructure, obtain following mainly
Conclusion: 1. by contrast experiment, draw SG-3 resin or SG-3 with SG-5 resin with certain proportion mix ratio individually with SG-5 tree
Fat material property is more preferable, is suitable for producing feedwater piping, has been used for actual production.2. at FWR-Z, SMS318, Ca-Zn with organic
In four kinds of stabilizers of stannum, FWR-Z stabilizer performance is worst.Water-feeding pipes should use organotin, Ca-Zn, SMS-318 stabilizer.Pipe
Part stabilizer cannot be used for producing tubing, jelly grade too much can be made because of in-lubricant excessive, affect the mechanical properties.3. at this
Under the experimental condition of literary composition, the effect that three kinds of full sulfuration micropowder art rubber improves the impact strength of PVC system is different, powder fourth
Nitrile rubber is better than acrylate rubber, and acrylate rubber is better than carboxy terminated nitrile rubber.When powdered rubber content is below 5 parts,
The impact strength of co-mixing system rises after falling before.When PNBR is 3 parts, the impact strength of co-mixing system rises relatively
Hurry up, exceed the impact strength of pure PVC, but be necessary to improve further the amplitude of increase, keep hot strength not reduce.4. exist
Under experimental condition herein, by observing the microstructure of PNBR/PVC co-mixing system section, find different microcell
Middle PNBR dispersion situation is different, and rubber has the bundles of phenomenon of gathering, also has finely dispersed phenomenon.Use banburying side
When formula is blended, it is possible to observe the microcell that PNBR dispersion size is less, its single particle is closely sized to 100nm, in
Existing fundamental particle dispersity.Ultra-fine fully vulcanized powder rubber to the study on the modification 5. of RPVC at this paper test bar
Under part, genuine milk rubber shares with powder butyronitrile rubber, can improve the interface of powder butyronitrile rubber and PVC, make co-mixing system rush
Hit intensity is improved, and in system microstructure, rubber particles dispersion size is less, shows coordination plasticizing effect.6.1 parts with
After upper powdered rubber mixes with PVC, the master stream property of compound is deteriorated, and affects the dispersion of powdered rubber granule, and then affects performance,
Powdered rubber surface appearance should be improved.The most under experimental conditions, the micro-cross-linking agent TAIC less than 0.1 part can be to a certain degree
Improve the mechanical property of PVC.In order to take into account processing characteristics and the requirement of product appearance quality in actual production, reduce cross-linking agent
After consumption, mechanical property is without significantly improving.
The water pipe obtained by this research has good intensity and toughness, but the easy corrosion and ageing of rubber, thermostability
Poor, affect the service life of water pipe, need to improve, it addition, the progress also needing to the change according to environment and production improves water
The toughness of pipe, antibiotic property, corrosion resistance, quiet performance, elasticity, environmental protection, wear-resisting, antistatic behaviour, tensile strength, spoke antifouling, anti-
The performance such as penetrate, fire-retardant.
