Description
Technical field：
The present invention relates to medical resin correlative technology fields, and in particular to a kind of infusion medical resin and preparation method.
Background technology：
Depressed, the excess capacity in market economy, downstream demand diversification, high-quality, safety and environmental protection require increasingly to improve
Complex environment under, production of resins enterprise only constantly reduces energy consumption by technological innovation, reduces pollution, reduces cost,
Thus there is PVC paste resin, CPVC resins, vinyl chloride-vinyl acetate resin, the third resin of chlorine, blending tree in the product function for improving product quality
Fat, high polymerization degree resin, matting resin, medical grade resins etc. are resin dedicated, to meet the market demand.
Wherein medical grade resins are mainly used in the pipeline of disposable transfusion device, blood transfusion apparatus and various medical extracorporal circulatory systems
With parts etc..As medical grade resins, it is desirable that it is without toxicant, stripping property is small, bio-compatible is on very good terms (such as hemolytic
It is low, anticoagulant property is good, hemoglobin denaturation degree is small etc.).Therefore, compared with universal resin, to the requirement of medical grade naval stores
Then more stringent, the residual quantity for essentially consisting in the noxious materials such as vinyl chloride, toluene, the nitrile group in medical grade resins requires to be micro-
Amount or zero.
With the improvement of people ' s living standards and the progress of medical technology, more and more disposable medical equipment are extensive
Applied to medical domain, develop in western developed country particularly rapid.The research of medical grade resins is concentrated mainly on resin modified
Aspect can reduce the toxicity of product by modification.
In terms of current statistical data, medical resin is applied to the quantity in medical field in China and only accounts for gross domestic product
1.2% or so, it can be seen that the annual requirement of medical resin be 150,000~300,000 t.But with domestic aging of population
With being gradually expanded for medical field, the demand to medical article will increasingly increase.In addition, as people are to consumption quality and body
The increasingly attention of health, toy for children raw material also gradually turn to medical grade resins, to improve the need of medical grade resins
Seek growth rate.
