Macromolecule fascia and method for preparing the same

Abstract

The invention relates to a polymer bandage and a preparation method thereof, which solves the technical problem of uneven distribution of prepolymers during storage of the bandage, and at the same time prevents the adhesiveness of the bandage after curing from decreasing. It is provided with a base material, The substrate contains polyurethane prepolymer, catalyst and filler. The weight percentage of polyurethane prepolymer in the bandage (the same below) is 20-50%, the catalyst is dimorpholine diethyl ether, and its content is 0.1-5%. The particle diameter is less than 100nm, and its content is 0.1-5%. The present invention can be widely used for surgical fixation.

Description

Technical field:

[0001] The invention relates to a surgical fixation material and a preparation method thereof, in particular to a polymer bandage and a preparation method thereof. Background technique:

[0002] Plaster bandage is the most common external fixation material in orthopedic treatment. Although the method of applying plaster is an essential treatment procedure, it brings obvious discomfort to orthopedic patients. Due to fracture treatment, plaster bandages need to be applied for 3-10 weeks, resulting in long-term contact between the patient's skin and plaster. This can easily cause itching, discomfort and inflammation, and the plaster is bulky, poor in strength, inelastic after curing, airtight, and will soften or break after soaking in water. In addition, the X-ray transparency is poor. After the plaster is applied, X-ray film examination cannot be carried out effectively. This is not conducive to checking the progress of fracture treatment, so it is impossible...
