Abstract
The invention discloses polymer gel and a preparation method thereof. Polyether polyol, a zinc catalyst, a plasticizer and isocyanate are taken as raw materials, a raw material formula and a proportion are adjusted, then the raw materials are subjected to a polymerization reaction, and the gel with excellent performance is formed. The polymer gel and the preparation method thereof have the advantages that the gel prepared by the formula and the production method disclosed by the invention is delicate and soft in handfeel, clear, transparent, good in ice-cold degree and high in toughness, therefore, the polymer gel is suitable for processing high-quality gel pillows.
Description
Technical field
The present invention relates to a kind of polymer gel and preparation method thereof.
Background technology
Gel refer to granular size at 1 dust to the mixture between 10 dusts.Macromolecular solution and some colloidal sol, under suitable condition, whole system can be transformed into a kind of stiff material of elastic semi-solid state, loses flowability.This phenomenon is called pectisation, and formed product is called gel or frozen glue.Colloidal particle in colloidal sol or the solution or polymer are interconnection under certain condition, form the space reticulated structure, have been full of the liquid as dispersion medium in the structure space, and a kind of so special dispersion system is called gel.There is not flowability.Large quantity of fluid is often contained in inside.
The defective of commercially available gel: the clear degree is poor, poor toughness, and long-time preservation can be hardened.This characteristic limitations the application of gel on higher gears time product.
Summary of the invention
The purpose of this invention is to provide a kind of polymer gel and preparation method thereof, this polymer gel can be used for preparing gel pillow.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of polymer gel, it is characterized in that: described polymer gel prescription is as follows in weight part: polyether glycol, hydroxyl value 32-35mgKOH/g, molecular weight is 5000,50-80 weight part, catalyzer 0.2-0.5 weight part, softening agent 10-30 weight part, isocyanic ester 10-30 weight part.
Further, described polyether glycol is 5020 or 330N.
Further, described catalyzer is zinc catalyst.
Further, described softening agent is hexanaphthene 1.2 dioctyl phthalate diisononyl esters.
A kind of preparation method of polymer gel, step is: (1) raw material is prepared: polyether glycol, catalyzer, softening agent are added in the reactor, speed with 500r/min mixes, time is among the 30min, change injection cylinder after mixing over to, and isocyanic ester places another injection cylinder, and is stand-by; (2) polyreaction: with the material in above-mentioned two injection cylinders, the thrust-augmenting nozzle by separately is by pump suction premixing tank, after mixing with 2000r/min stirring velocity moment, flow into polyreaction in the mould, temperature of reaction is 40-60 ℃, and fusion time is 7-12min, the finished product of discharging after finishing.
Further, the injection cylinder temperature all is controlled to be 30-40 ℃ described in the step (1).
The invention has the advantages that: by the gel that prescription of the present invention and production method are made, feel is fine and smooth soft, clear, ice-cold degree well, toughness is high, more is applicable to process high-quality gel product.
