A kind of organosilicon modified polyurethane synthetic glue and preparation method thereof

Abstract

The invention relates to an organic silicone modified polyurethane synthetic adhesive and a preparation method thereof. Traditional bandaging can easily cause displacement of a fracture portion, and accordingly pain of a patient is aggravated. The organic silicone modified polyurethane synthetic adhesive is prepared from, by mass, 35-37% of carbodiimide modification MDI, 17-19% of polyether glycol GE-210, 2-4% of polyether glycol GE-303, 26-28% of hydroxy-terminated polydimethylsiloxane, 1-2% of methyl-tri-(butanone-oxime) silane, 0.2-0.4% of sodium dodecyl sulfate, 0.1-0.2% of organic tin compounds, 1-3% of triethyl phosphate, 7-9% of aluminum hydroxide and 2-4% of ferric oxide. The invention further provides a preparation method of the organic silicone modified polyurethane synthetic adhesive. The organic silicone modified polyurethane synthetic adhesive serves as an adhering agent of a fixing and adhering band, the finished fixing and adhering band is packaged in an aluminum plastic bag to be in a non-solidification state, and the fixing and adhering band becomes hard when making contact with air and can be used for body position fixing after fracture of a person.

Description

technical field [0001] The invention relates to a silicone-modified polyurethane synthetic glue and a preparation method thereof, and also relates to the application of the synthetic glue as an adhesive for winding and consolidating tapes for quickly repairing damaged objects, belonging to the technical field of polymer materials. Background technique [0002] It is known in the field of medicine that reactors are often used to synthesize target products. The interlayer of the reactor can be connected with different cold and heat sources (refrigerated liquid, hot water or hot oil) for cyclic heating or cooling reaction. Its working principle is: through the interlayer of the reactor, inject a certain temperature of hot-melt medium or cooling medium to heat or cool the materials in the reactor. [0003] Usually, in terms of medical equipment, people use methods such as bandages to fix the position of the fracture site, so as to avoid the displacement of the damaged site and ...

Problems solved by technology

In addition, in terms of household items, such as chair legs, fishing rods, metal pipes, plastic pipes, etc. are broken or cracked, due to the lack of professional tools, they often cannot be fixed or repaired in a short period of time. People usually dispose of them by discarding them. thus causing huge waste

In terms of engineering construction, if the steam pipe breaks, it will affect people's production and life in mild cases, and cause accidents in severe cases.
