Description

A kind of preparation method of the pressure gelatin with low peel strength
Technical field
The present invention relates to medical pressure sensitive adhesive technical field, the preparation of more particularly to a kind of pressure gelatin with low peel strength Method.
Background technology
Eye speculum is hospital ophthalmology Special medical equipment, it is used to expand eyelid(Eyes above and below two during eyelid Block tissue), for majority for making ophthalmologic operation, it is the surgical field of view for expanding doctor that it, which is acted on,.General eye speculum is screw turn-knob Eye speculum, its operating method are:Eyelid is caught on the hook portion of eye speculum, then precession screw rod, eyelid bar is driven at both ends(That is the application Clamp arm)Outside diffusion, eyelid are expanded.It follows that need what both hands operated during traditional eye speculum, i.e. a hand need Eye speculum is held, to stablize its position, its another hand needs rotary screw, and to expand eyelid, so operation is to main operation For hand, it appears it is rather troublesome, particularly in ophthalmologic operation is done, general operating doctor when being not required secondary manipulator to help, In order to expand surgical field of view, its temporary adandonment of having to is ongoing to be operated to operate eye speculum, and this operation midway is suspended Situation be easy to cause operation contingency, be unfavorable for that operating doctor is smooth to perform the operation, and eyelid is operated out as secondary manipulator During device, since the position of eye is narrow and small, space is limited, and double operated to eye undoubtedly increases operating difficulty, also easily Accident surgery is caused, there are inconvenient problem with use for the traditional eye speculum operated therefore, it is necessary to both hands.
Realize that eye speculum and the fixation of circumference of eyes position are a kind of possible fixed forms by pressure sensitive adhesive binding agent, Eye speculum is fixed and is bonded in around eye, a hand can be avoided the need for and go to buttress the trouble of eye speculum, and then can be A hand is liberated in surgical procedure, unfortunately, traditional eye speculum simultaneously has this design, while existing medical pressure sensitive adhesive is used In on medical adhesive tape, the peel strength of medical adhesive tape is not less than 1.541N/cm, and peel strength is excessive, when it is soft with circumference of eyes After soft skin bonding, it is not easy to tear and, skin is drawn its length long, and secondary injury can be caused to patient, meanwhile, it is existing Some pressure sensitive adhesives when in use, can still have the problem of leaving residual glue, after shutting down adhesive tape, the skin surface at glued place Sticky sense is had after being touched with hand, the causative agent and residue being easily infected with surgical procedure, after patient carries out operated eye, contamination Causative agent and residue easy infection eye, thereby result in circumference of eyes inflammation, redness, be unfavorable for the recovery of eyes of patients wound.
The content of the invention
The goal of the invention of the present invention is:For above-mentioned problem, there is provided a kind of pressure with low peel strength is bright The preparation method of glue, by varying the formula and preparation process of existing pressure gelatin binder, reduces the stripping of pressure gelatin binder Intensity, so solve the problems, such as it is existing pressure gelatin binder present in peel strength it is excessive, it is easy residual matrix, ensure open eyelid While device can be fixed on circumference of eyes, eye speculum is facilitated to be taken off at circumference of eyes.
The technical solution adopted by the present invention is as follows:A kind of preparation method of the pressure gelatin with low peel strength, its feature It is, comprises the following steps:
Step 1, by the propyl methacrylate of 60-80 parts by weight, the methyl methacrylate of 5-8 parts by weight, 3-6 parts by weight Acrylic acid and the initiator of 0.5-2 the parts by weight stirring and dissolving in suitable ethyl acetate solvent, then heat reaction and are gathered Polymer solution;
Step 2, the diatom ooze of addition 8-13 parts by weight and the dispersant of 0.5-1 parts by weight into polymer solution, are stirred Uniformly, mixed solution is obtained;
Step 3, the Nano titanium dioxide of addition 2-5 parts by weight and the curing agent of 0.5-1 parts by weight into mixed solution, stirring Be uniformly mixed, obtain glue, glue is coated on matrix to obtain the final product.
Further, in step 1, the mixing speed in course of dissolution controls the temperature in 180rad/min, heating reaction For 40-50 DEG C.
Further, in step 2, mixing speed control exists(300-350)Rad/min, whipping temp control 45 DEG C with Under.
Further, in step 3, mixing speed control is in 500rad/min.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows:A kind of tool provided by the invention There is the preparation method of the pressure gelatin of low peel strength, mainly solve the peel strength mistake present in existing pressure gelatin binder Greatly, the problem of easily remaining matrix, by varying the formula and preparation process of existing pressure gelatin binder, glues obtained pressure gelatin The peel strength of agent is tied only in below 6.58N/m, while ensureing that eye speculum can be fixed on circumference of eyes, facilitates eye speculum Taken off at circumference of eyes, after eye speculum is taken off, skin surface noresidue is smooth dry without sticky sense, surface when finger touches Dry, using effect is good.
