Embodiment Construction

[0025] Embodiments of the present invention are accomplished by the following steps:

[0026] 1. Rinsing and standing:

[0027] Take fresh adult or pediatric (including infants and fetuses) materials (within 6 hours after death), select suitable caliber cannulas in the arteries and (or) veins, and repeatedly flush the pipeline with 5% sodium citrate saline at the intubation site, Until the vein outflows clearer fluid. Then place the specimen in a washbasin filled with clean water, float in the water for 6-12 hours, then use a 50ml syringe to draw 8-10% formalin and pour it into each intubation site to fully fix the specimen, and finally put it in clean water and let it stand 12-24h.

[0028] 2. Prepare the new environmental protection human body pipeline casting mold filler of the present invention:

[0029] Prepare an appropriate amount of filler according to the ratio of the above mold filler CYD-128: RF-400: DMP-30: defoamer: ZY-1618 = 100: 15: 5: 0.5: 45 and add an appr...

Abstract

The invention relates to an environmental-friendly human pipeline casting filler and a preparation method thereof. The filler is prepared from the following compositions in parts by weight: 100 parts of CYD-128(E-51) epoxy, 15ml of epoxy high performance toughening modifier RF-400, 5 parts of 2, 4, 6 tri(dimethylamino methyl) phenol (DMP-30), 0.3-0.5 part of epoxy defoamer and 45-50 parts of modified alicyclic amine epoxy curing agent ZY-1618. The invention has the advantages of easy preparation, convenient operation, finishing by once perfusion, good filler fluidity, little perfusion resistance, vigorous and plump forming, fineness, beauty, small shrinkage factor, environmental protection, no toxicity, very strong support force of a casting trunk and good flexibility of a branch.

Description

technical field [0001] The invention relates to human anatomy casting technique. technical background [0002] With the rapid development of the chemical industry, the casting technology of human anatomy has also been developed rapidly, and many casting fillers with different properties are constantly emerging. At present, there are the following types of mold fillers commonly used in China: self-curing tray materials, perchlorethylene, epoxy resin, ABS, etc., but in the actual application process, all kinds of fillers have their advantages and disadvantages. For example, self-curing dental tray materials have the advantages of full molding and strong support, but the solidification time is short, the surface of the molded specimen is rough, and the flexibility is poor; perchlorethylene has the advantages of good flexibility and beautiful molding, but it needs multiple injections and supports If the force is not strong, it is easy to deform the mold. Epoxy resin has high m...
