Abstract
The invention discloses a soft hydrophilic corneal contact lens manufacturing formula, and relates to the field of production of contact lenses. The soft hydrophilic corneal contact lens manufacturing formula mainly comprises the following components: 500 grams of 2-ethoxyethanol, 25 grams of methyl methacrylate, 20 grams of methacrylic acid, 20 grams of styrene, 800 grams of butyl acetate, 10 grams of 2-mercaptoethanol, 100 grams of propylene glycol, 1,000 grams of hydroxyethyl methacrylate and 5 grams of hexamethylene diisocyanate. A manufactured soft hydrophilic corneal contact lens is high in softness and elasticity and difficult to fade, is stable when being formed and colored, can be more comfortable to wear, and is free of strong irritation effects.
Description
Technical field:
The present invention relates to contact lens and manufacture field, be specifically related to a kind of flexible hydrophilic contact lens and make formula.
Background technology:
Contact lens, or contact lens, be that one is worn on cornea, in order to correct defects of vision or to protect the eyeglass of eyes.It comprises rigid and soft two kinds, contact lens are not only from having brought very large improvement to accessibility aspect in appearance the ametropia patients such as myopia, long sight, astigmatism, and the visual field is broad, to look thing true to nature, this external control adolescent myopia, astigmatism development, treat the aspects such as special illness in eye and also brought into play special effect.But what most used is all soft contact lens, because of the difference of hardness of material, so than being easier to split and by scratch.There is the user of part often can reflect that slight crack and breach appear in the edge of eyeglass.By analysis, normally nail scratch eyeglass, too bend that eyeglass, eyeglass adhesion, dehydration become fragile and protein to accumulate be too much the reason that eyeglass breaks.
For the friend who wears for the first time contact lens or colorful contact lens, can not feel like oneself, wherein possible reason be exactly because: cornea anoxic.Under normal circumstances, our cornea needs " breathings ", and the oxygen transmission rate of contact lens is important indicators for assessment contact lens material quality, and therefore to have a higher oxygen transmission rate be very important factor of selection eyeglass to lens materials.
Cornea long term hypoxia easily causes the related complication of cornea; such as chronic corneal edema, cornea rebirth blood vessel etc.; contact lens especially colorful contact lens have met the vast personage's of liking to be beautiful demand; but must test and join the contact lens products that is applicable to oneself by the program of standard, and carry out daily nursing in strict accordance with care program.Pay special attention to, the oxygen transmission rate of the eyeglass of unlike material has very large difference, and also just there is very large difference the time that can wear.Therefore well avoid, because wear the cornea anoxic problem that contact lens cause for a long time, can wearing continuously by ultra-long time, meet the demand of nap simultaneously.And the wetting ability of contact lens and oxygen-permeable also can impact human eye to a great extent.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of flexibility good, and elasticity is good, and the flexible hydrophilic contact lens that is difficult for fading is made formula.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of flexible hydrophilic contact lens is made formula and is comprised following component:
Ethylene glycol ethyl ether: 500 grams
Methyl methacrylate: 25 grams
Methacrylic acid: 20 grams
Vinylbenzene: 20 grams
Butylacetate: 800 grams
Second one mercaptoethanol: 10 grams
Propyleneglycoles: 100 grams
Hydroxyethyl methylacrylate: 1000 grams
Hexamethylene diisocyanate: 5 grams
The making step of making the contact lens of formula made according to flexible hydrophilic contact lens is:
1, previously prepd ethylene glycol ethyl ether, methyl methacrylate, methacrylic acid, vinylbenzene, butylacetate, second one mercaptoethanol, propyleneglycoles, hydroxyethyl methylacrylate are put in Rotary Evaporators and mixed successively;
2, the revolution of Rotary Evaporators is arranged on to 450 revs/min, then slowly Rotary Evaporators is heated;
3, while temperature being added to 70 ℃, stop heating, continue to keep the rotating speed of 450 revs/min to rotate 2 hours;
4, after 2 hours, the rotation of the evaporimeter that stops the rotation joins hexamethylene diisocyanate in Rotary Evaporators, then makes it naturally cool to normal temperature, after under reaching normal temperature condition, naturally places 30 minutes;
5, cooled Rotary Evaporators is put in 0-5 ° of refrigerating chamber and refrigerated 12 hours, then take out, now the raw material configuration effort of flexible hydrophilic contact lens completes.
Adopt the wetting ability of the flexible hydrophilic contact lens of above method and formula making generally can reach 30%-80%; wetting ability and high oxygen permeability are better; therefore normally wearing spends the night also can not cause stimulus effects to human eye; having extended the time of wearing has improved the protection to human eye; and elastomeric effect also makes wearer more comfortable, extend the work-ing life of glasses.
The invention has the beneficial effects as follows: the flexibility of the flexible hydrophilic contact lens of making according to this formula and method is good, elasticity is good, be difficult for fading, more stable in the time carrying out moulding and colouring, the flexible hydrophilic contact lens after making is worn the more comfortable strong impulse effect that do not have.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete example, further set forth the present invention.
A kind of flexible hydrophilic contact lens is made formula and is comprised following component:
Ethylene glycol ethyl ether: 500 grams
Methyl methacrylate: 25 grams
Methacrylic acid: 20 grams
Vinylbenzene: 20 grams
Butylacetate: 800 grams
Second one mercaptoethanol: 10 grams
Propyleneglycoles: 100 grams
Hydroxyethyl methylacrylate: 1000 grams
Hexamethylene diisocyanate: 5 grams
The making step of making the contact lens of formula made according to flexible hydrophilic contact lens is:
6, previously prepd ethylene glycol ethyl ether, methyl methacrylate, methacrylic acid, vinylbenzene, butylacetate, second one mercaptoethanol, propyleneglycoles, hydroxyethyl methylacrylate are put in Rotary Evaporators and mixed successively;
7, the revolution of Rotary Evaporators is arranged on to 450 revs/min, then slowly Rotary Evaporators is heated;
8, while temperature being added to 70 ℃, stop heating, continue to keep the rotating speed of 450 revs/min to rotate 2 hours;
9, after 2 hours, the rotation of the evaporimeter that stops the rotation joins hexamethylene diisocyanate in Rotary Evaporators, then makes it naturally cool to normal temperature, after under reaching normal temperature condition, naturally places 30 minutes;
