Abstract
The present invention relates to a kind of new medical high polymer material, the new medical high polymer material is made up of the component of following parts by weight：60 80 parts of polypropylene, 10 20 parts of butadiene-styrene rubber, nanoscale is slight 20 40 parts of 30 40 parts of dicalcium powder and developer.The advantage of the invention is that：New medical high polymer material of the present invention, after with the addition of additive, it is possible to increase some mechanical properties of the medical macromolecular materials, improve the rigidity and toughness of polypropylene medical macromolecular materials.
Description
Technical field
The invention belongs to medical field of new materials, more particularly to a kind of new medical high polymer material.
Background technology
Medical macromolecular materials be by be directly used in human body or with health it is closely related for the purpose of, therefore to enter face
The material of bed service stage has strict requirements：
To medical macromolecular materials performance requirement itself：Resistance to biodeterioration, physical and mechanical properties are stable, are easily processed into
Type, material are easy to get, price is appropriate.
Body effect requirement to medical macromolecular materials：It is nontoxic, without heat source response, it is not carcinogenic, not teratogenesis, do not caused
It is quick reaction or interference human body immune mechanism, do not destroy adjacent tissue, also not generating material Surface calcification deposition, for blood
The material of contact, it is desirable to have good blood compatibility, not blood coagulation.
The requirement for producing and processing for medical macromolecular materials：Objectionable impurities, content of beary metal can not be brought into be surpassed
Mark, processing aid have to comply with medical standard.
And the requirement characteristic of medical high polymer is not only required with macromolecule for interventional medical device, also require its tool
There is X ray developability, typically by adding percentage by weight 10-40% developer in macromolecule matrix such as：Barium sulfate, bismuth
Salt, tungsten etc..Developer surface free crosses the modification that organises, poor with high molecular interface binding power, can cause high molecular power
Learn hydraulic performance decline.
Polypropylene due to its excellent mechanical property, good heat resistance, processing stablize, it is safe and non-toxic, remarkably
Outward appearance is widely used in medical instruments field, and its dosage is only second to polyvinyl chloride, occupies second.But polypropylene also have it is bright
The shortcomings that aobvious：Impact strength is relatively low, and toughness is poor, and toughness further reduces after adding developer, in use at thin-walled
Easily there is the situation of breach or fracture.Such as addition macromolecular toughening agent of conventional polypropylene toughening modifying method can improve poly-
The toughness of propylene, but polyacrylic rigidity can be lost, cause material modulus to drastically reduce, certain enhancing need to be added in polypropylene
Filler, conventional reinforcing agent such as glass fibre and talcum powder etc. can not be applied due to biological safety and other problemses.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of new medical high polymer material, to solve the above problems.
In order to solve the above technical problems, the technical scheme is that：A kind of new medical high polymer material, its innovative point
It is：The new medical high polymer material is made up of the component of following parts by weight：Polypropylene 60-80 parts, butadiene-styrene rubber 10-
20 parts, nanoscale is slight dicalcium powder 30-40 parts and developer 20-40 part.
Further, the new medical high polymer material is made up of the component of following parts by weight：Polypropylene 65-75
Part, butadiene-styrene rubber 14-16 parts, nanoscale is slight dicalcium powder 34-36 parts and developer 25-35 part.
Further, the new medical high polymer material is made up of the component of following parts by weight：70 parts of polypropylene, fourth
15 parts of benzene rubber, nanoscale is slight 30 parts of 35 parts of dicalcium powder and developer.
The advantage of the invention is that：New medical high polymer material of the present invention, after with the addition of additive, it is possible to increase the doctor
With some mechanical properties of high polymer material, the rigidity and toughness of improvement polypropylene medical macromolecular materials.
