Embodiment 1

[0041] Embodiment 1 (taking blood vessels as an example)

[0042] Perfuse blood vessels of the whole body of adults or individual organs (such as heart, liver, kidney, brain, etc.), including large, medium, small and small blood vessels.

[0043] The specific volume ratio of preparation is:

[0044] CYD-128:LNBR26:RF-PPGDGE400:DMP-30:ZY-1784:

[0045] RF-400=100:(20-24):(35-40):15:45:(40-45).

[0046] According to the above method of preparing the improved environment-friendly human body pipeline casting filler of the present invention, the specific operation method is implemented. Under the condition that the ratio of CYD-128:DMP-30:ZY-1784=100:15:45 remains unchanged, when the blood vessel is perfused, according to the blood vessel Adjust the amount (ratio) of LNBR26 for different diameters. First infuse a certain amount of high concentration

[0047] (CYD-128:LNBR26=100:24) of filler, and then perfuse with low concentration (CYD-128:LNBR26=

[0048] 100:20), stop per...

Embodiment 2

[0050] Embodiment 2 (taking blood vessels as an example)

[0051] Perfuse blood vessels in children (including infants and fetuses), including medium and small ducts (diameter 0.3-10mm) and small ducts (diameter less than 0.3mm).

[0052] The specific volume ratio of the preparation is: CYD-128:LNBR26:RF-PPGDGE400:DMP-30:ZY-1784:

[0053] RF-400=100:22:(35-40):15:45:(40-45).

[0054] According to the above-mentioned volume ratio preparation of the present invention's improved environment-friendly type human body pipeline casting mold filling agent, the method for specific operation is implemented. Under the condition of constant ratio of CYD-128:DMP-30:ZY-1784=100:15:45, because children's blood vessels are For small and medium pipes, there is little difference in pipe diameter. The appropriate amount of LNBR26 is 22ml (CYD-128 epoxy resin is 100ml). The cast specimens made in this way have the characteristics of certain rigidity in the trunk and good flexibility in the sma...

Abstract

The invention provides a human body canal cast filler and a preparation method of the human body canal cast filler; and the human body canal cast filler is good in physicochemical performance, strong in acid-base resistance, good in flexibility and stronger in support force. The human body canal cast filler is prepared by the components according to the volume ratio: 100ml of cyclodextrin (CYD)-128 type epoxy resin, 20-24ml of liquid-state nitrile rubber, 35-40ml of polypropylene glycol diglycidyl ether, 15ml of 2, 4, 6-tri-(dimethylamino methyl) phenol (DMP-30), 45ml of modified polyether amine epoxy resin curing agent ZY-1784 and 40-45ml of high-performance epoxy resin toughening modifier (RF-400). The human body canal cast filler is easy in preparation as well as simple and convenient in operation, can be completed by once injection without after-teeming, and can be immediately prepared when injection is not sufficient. The invention has the characteristics of being good in fluidity, low in injection resistance, full in molding, fin and attractive, low in contractibility rate, environment-friendly and the like.

Description

technical field [0001] The invention relates to human anatomy casting technique. technical background [0002] Epoxy resin is one of the most widely used matrix resins for polymer-based composite materials. It has good comprehensive mechanical properties such as good heat resistance, high mechanical strength and low shrinkage, and is widely used in human anatomy casting technology. However, due to the high crosslinking density and large internal stress of the cured epoxy resin, its main disadvantages are brittleness, poor fatigue resistance and impact toughness, which limit its application as a human body pipeline casting filler. Therefore, the toughening modification of epoxy resin has become the main direction of research on the modification of epoxy resin mold fillers. At present, due to the good flexibility of liquid NBR, it has good compatibility with epoxy resin. The mold filler formed by adding liquid NBR to toughen and modify the epoxy resin is used for perfusion ...
