Abstract

The invention relates to a low-calorie and low-odor polyurethane medical fixing pad material and a preparation method thereof, belonging to the technical field of polyurethane applications. The polyurethane medical fixing pad material of the present invention is composed of component A and component B, the weight ratio of component A and component B is 1:0.9-1.1, wherein: (1) component A consists of the following parts by weight Raw material composition: polyether polyol A50‑70, polyether polyol B10‑30, polyether polyol C10‑30, polyether polyol D10‑30, chemical foaming agent 2.0‑4.0, catalyst 0.3‑1.5, foam stabilization Agent 2.0‑4.0; (2) Part B is polymerized diphenylmethane diisocyanate. The polyurethane medical fixing pad material of the invention releases low heat and little irritating odor during the molding process; the invention also provides a simple, energy-saving and consumption-reducing preparation method.

Description

technical field [0001] The invention relates to a low-calorie and low-odor polyurethane medical fixing pad material and a preparation method thereof, belonging to the technical field of polyurethane applications. Background technique [0002] As a thermal insulation material, polyurethane is widely used in refrigerators, freezers, cold storage, external wall insulation and other fields. At the same time, polyurethane is also a filling material, which can be used for building waterproofing, roof leak plugging, mine reinforcement and water plugging, etc. [0003] As a medical auxiliary product, medical fixation pads are widely used to fix the patient's surgical position during brain surgery, tumor radiation surgery, etc., as well as postoperative fixation of other operations. As a filling material for the fixed pad, polyurethane has the characteristics of fast molding and easy molding, and the fixed pad of polyurethane material is shaped for the individual, so it has strong i...
