Description
Technical field
The present invention relates to medical pressure sensitive adhesive technical field, more particularly to a kind of pressure sensitive adhesive binding agent for eye speculum bonding
Preparation 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 for the pressure-sensitive of eye speculum bonding
The preparation method of glue caking agent, by varying the formula and preparation process of existing pressure gelatin binder, reduces pressure gelatin binder
Peel strength, and then solve the problems, such as it is existing pressure gelatin binder present in peel strength it is excessive, it is easy residual matrix, protecting
While card eye speculum 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 pressure sensitive adhesive binding agent for eye speculum bonding,
It is characterised in that it includes following steps：
Step 1, weigh each component by weight, by 50-60 parts of acrylate soft monomers, 4-7 parts of acrylate hard monomers, 0.5-
2 parts of initiators and 4-7 parts of castor oil are kneaded 60-90min in open mill, obtain just mixed thing；
First mixed thing, be dissolved in suitable organic solvent by step 2, then adds the synthetic rubber of 3-5 parts by weight, is stirred
It is even, make synthetic rubber dispersed, obtain milk；
Step 3, send into vulcanizing press the vulcanizing agent for adding 0.5-1 parts by weight into milk to be vulcanized the milk,
Pressure sensitive adhesive is obtained after vulcanization.
Further, in step 2, when being stirred, mixing speed control is controlled 50 in 300rad/min, whipping temp
℃。
Further, in step 3, curing temperature is maintained at 40-60 DEG C, and vulcanization time is controlled in 5-10s, vulcanizes pressure
Control is in 1-2MPa.
Further, the acrylate soft monomer is isooctyl methacrylate；The acrylate hard monomer is methyl
Methyl acrylate；The synthetic rubber is butadiene-styrene rubber.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：A kind of use provided by the invention
In the preparation method of the pressure sensitive adhesive binding agent of eye speculum bonding, the stripping present in existing pressure gelatin binder is mainly solved
The problem of intensity is excessive, easy residual matrix, by varying the formula and preparation process of existing pressure gelatin binder, makes obtained pressure
The peel strength of gelatin binder is convenient while ensureing that eye speculum can be fixed on circumference of eyes only in below 7.87N/m
Eye speculum is taken off at circumference of eyes, after eye speculum is taken off, skin surface noresidue, without sticky sense, surface when finger touches
Lubricous dry, using effect are good.
