Abstract
The present invention now provides a kind of preparation method of the TPE material for medical transfusion bag:A, the batch mixing in batch mixer first fully absorbs plastic cement processing oil with SEBS rubber resins, then mixes well the SEBS rubber resins, PP, bimaleimide resin, metallocene PE, the auxiliary agent that absorb plastic cement processing oil after-tack in proportion, obtains mixture;B, it is 38 draw ratio to be added in the mixture:1~32:1, melting mixing in the double screw extruder that extrusion temperature is 260~280 DEG C, rotating speed is 300~500rpm;C, the TPE material for medical transfusion bag is made after extruded, tie rod, air-cooled, pelletizing and drying process successively.Medical transfusion bag prepared by elastomeric material provided by the invention not plasticizer-containing, does not absorb the drug, reduces the risk that drug is adsorbed.
Description
Technical field
The invention belongs to plastic material fields, and in particular to a kind of preparation method of TPE material for medical transfusion bag.
Background technology
Currently, disposable transfusion device both domestic and external mostly uses polyvinyl chloride (hereinafter referred to as " PVC ") material of DEHP plasticising
It is made.Constantly there are PVC products that there is the related report that suction-operated causes curative effect to reduce to some drugs, by supervision department
The extensive concern of door.The risk that drug lessens the curative effect is not adsorbed using TPE material.Contain plasticizer in PVC, plasticizer
Molecular structure is similar to hormone, if the danger that long-term consumption may cause breeding unsoundness, even cause monster, cancer.
Environmental Hormone means that external factor interferes the endocrine chemical substance of organism.In the environment it is remaining it is micro this
Class compound enters in vivo via food chain, forms false hormone, transmit false chemical signal, and the internal lotus of influence itself
You cover content, and then the script mechanism of disturbance endocrine, can cause endocrine disorder.So being badly in need of a kind of not plasticizer-containing of exploitation
Medical transfusion bag, reduce the influence developed to juvenile.
