Description

one

1bot1) ete1; not related to medicine and can be used in trauma ..- to) when it turns out1 in medical jungle fracture, injury, and other injuries of the extremities.

Known immobilizirovan)) UKI 1nd non-material on the basis of (hydroxyl-containing polyester, polyisocyanate, all-important agent and catalyst.

However, the known non-material does not allow fixing the damaged parts of the body at temperatures below 0 ° C.

The aim of the invention is the possibility of fixing the damaged parts of the body at a temperature below 0 ° C.

The goal is achieved by the fact that in an immobilizing foam based on hydrokor and l containing nolyafnra, niolisotspanata. blowing agent, catalyst. The catalyst contains a mixture of n-hydroxyl-containing, mono-hydroxyl-containing tertiary amines and a tertiary a.min, which does not contain hydroxyl groups in the next proportional ratio of components, w / v:

The table shows the contents of the components for the proposed blends.

Immobilizing foam was prepared as follows.

To obtain the indicated compositions, the components of examples 1-3 were carefully displaced in a mixer with a root or propeller mixer with the rotation speed of the stirrer from 10 to 400 rpm, at 5-30 ° C, and the resulting mixture was stored separately from the polyisocyanate 20 until use. For example, the composition specified in example 3 was prepared as follows.
