Abstract
The invention discloses a medical PVC shading aggregate. The medical PVC shading aggregate is good in shading effect and especially has a very good shielding effect on blue and purple light and ultraviolet light. The non-light-transmittance rate reaches relative standards of the industry, the processing performance is good, the product passes the national drug test standard test, high-elasticity design is adopted for a shading soft pipe material, the mechanical property of the medical PVC shading aggregate is close to that of polyurethane, and the medical PVC shading aggregate can be well compounded with PU, PVC transparent materials and PE materials and passes chemical and physical tests after standard correction of a national shading infusion device.
Description
Technical field
The invention belongs to field of medical materials, specifically, the present invention relates to a kind of medical PVC lucifuge pellet.
Background technology
Pvc pipe has good chemical proofing, mechanical property and electrical property, but its fast light and poor heat stability.By processing modified pvc plastics, can be widely used for making blood storage bag, transfusion bags, and the goods such as blood catheter, artificial peritonaeum, artificial urethra, pocket type artificial lung, heart catheter and artificial heart.The second-order transition temperature of pvc is higher, and material hardness is large, machine-shaping difficulty.Therefore, generally all in pvc resin, softening agent and other auxiliary agent is added.At present, work in-process is still using dioctyl phthalate (DOP) as primary plasticizer.But dioctyl phthalate (DOP) is lower-molecular substance, easy migration precipitation.The pvc of dioctyl phthalate (DOP) plasticising is used for medical catheter or container, is mixed in liquid or blood, dioctyl phthalate (DOP) will be caused to enter human body with liquid or blood because dioctyl phthalate (DOP) is easily separated out.In order to ensure the wholesomeness of pvc medical plastic, external developing that toxicity ratio dioctyl phthalate (DOP) is lower, dioctyl phthalate is less near migration precipitation new plasticizer, the polyester higher comprising the good citric acid ester type of wholesomeness, molar mass and other polymeric plasticizer.In the stablizer of pvc processing, lead salt is poisonous to blood, causes severe anemia, and cadmium salt more very; And pink salt and epoxy soybean oil better.
Summary of the invention
A kind of medical PVC lucifuge pellet, is characterized in that being made up of according to massfraction meter following component:
Wherein, the described PVC pellet polymerization degree is between 1000-1500.
Described uv-absorbing agent is UV328.
Described oxidation inhibitor is PhosphiteA.
A kind of medical PVC lucifuge pellet, described preparation technology is:
(1) raw material mixing: by other auxiliary materials such as PVC pellet and Xylitol, titanium dioxide, uv-absorbing agent, oxidation inhibitor, successively add in high-speed mixer in proportion, make material be warming up to 140-160 degree through material and mechanical self-friction, then through cold mixer, material is down to 40-50 degree;
(2) extruding part: the material that step (1) obtains is joined fusing in twin screw extruder, and mix further.By porous mouth mould, form many billots, then cut into pellet.
Beneficial effect of the present invention is: this product light-shading effect is good, particularly has good bridging effect to livid purple light and UV-light, and light tight rate reaches industry relevant criterion.Processing characteristics is excellent.Product is by national medicine inspection standard testing.The soft materials in the tube of lucifuge adopt high-elastic design, and mechanical property, close to urethane, can expect compound well with PU, PVC transparent material, PE, closes light proofing infusion apparatus repair the chemistry after being marked with and physical testing by country.Non-neighboring benzaldehyde product can be changed into, also can increase low temperature resistant effect.
