Description
Technical field
The present invention relates to PVC water pipe technical field, particularly relate to a kind of antistatic ultra-fine fully vulcanized powder rubber polychlorostyrene second
Alkene composite water pipe and preparation method thereof.
Background technology
Plastic pipe should have high intensity and high tenacity simultaneously.RPVC (PVC-U) water-feeding pipes toughness is not
Foot, easy booster under the effect of external condition, improving the mechanical property of PVC-U material is the effective of raising product service life
Approach." the ultra-fine fully vulcanized powder rubber study on the modification to RPVC " literary composition is for this practical problem, from increasing
Basic ideas tough, Reinforced PVC-U material property are set out, and use high model resin extruded PVC-U water-feeding pipes first, adopt first
With full sulfuration ultra fine powder rubber blending and modifying PVC-U material, inquire into the effect of micro-cross-linking agent chemical modification PVC-U material.
By testing the mechanical property of PVC-U system, observe the microstructure of blending modification system, obtain following Main Conclusions: 1. logical
Cross contrast experiment, show that SG-5 resin material performance individually used by SG-3 resin or SG-3 Yu SG-5 resin with certain proportion mix ratio
More preferably, it is suitable for producing feedwater piping, has been used for actual production.2. stable with organotin four kinds at FWR-Z, SMS318, Ca-Zn
In agent, FWR-Z stabilizer performance is worst.Water-feeding pipes should use organotin, Ca-Zn, SMS-318 stabilizer.Pipe fitting stabilizer is not
Can be used for producing tubing, jelly grade too much can be made because of in-lubricant excessive, affect the mechanical properties.3. at test bar herein
Under part, the effect that three kinds of full sulfuration micropowder art rubber improves the impact strength of PVC system is different, and PNBR is better than
Acrylate rubber, acrylate rubber is better than carboxy terminated nitrile rubber.When powdered rubber content is below 5 parts, co-mixing system
Impact strength rises after falling before.When PNBR is 3 parts, the impact strength of co-mixing system rises very fast, exceedes pure
The impact strength of PVC, but it is necessary to improve further the amplitude of increase, keep hot strength not reduce.4. in test herein
Under the conditions of, by observing the microstructure of PNBR/PVC co-mixing system section, find powdered nitrile rubber in different microcell
Rubber disperse situation is different, and rubber has the bundles of phenomenon of gathering, also has finely dispersed phenomenon.When using banburying mode to be blended,
Being able to observe that the microcell that PNBR dispersion size is less, its single particle is closely sized to 100nm, presents fundamental particle
Dispersity.Ultra-fine fully vulcanized powder rubber to the study on the modification 5. of RPVC under this paper experimental condition, genuine milk
Rubber shares with powder butyronitrile rubber, can improve the interface of powder butyronitrile rubber and PVC, make co-mixing system impact strength be carried
Height, in system microstructure, rubber particles dispersion size is less, shows coordination plasticizing effect.More than 6.1 parts powdered rubbers with
After PVC mixing, the master stream property of compound is deteriorated, and affects the dispersion of powdered rubber granule, and then affects performance, should improve powder rubber
Glue surface appearance.The most under experimental conditions, the micro-cross-linking agent TAIC less than 0.1 part can to a certain degree improve the mechanics of PVC
Performance.In order to take into account processing characteristics and the requirement of product appearance quality in actual production, after reducing the consumption of cross-linking agent, mechanical property
Can be 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.
