Description
Technical field
The present invention relates to optometric technology fields more particularly to high-intensity resin eyeglass and preparation method thereof.
Technical background
In international trade, the export volume of China's eyeglass industry, overall is in up-trend.However, some items
The very excellent domestic eyeglass of energy index, only because FDA（Food and Drug Administration)）Detect shock resistance
Test unqualified, product cannot be introduced into US and European market.
Invention content
In terms of solving the problems, such as above-mentioned eyeglass outlet, present invention aims at provide a kind of high-intensity resin eyeglass
And preparation method thereof, it solves.
The above-mentioned technical problem of the present invention is mainly to be addressed by following technical proposals：
A kind of high-intensity resin eyeglass and preparation method thereof, which is characterized in that including：
A. lens center thickness CT is designed
Lens center thickness CT is：1.6 mm±0.2 mm
B. one-step solidification technique
By lens center thickness CT technological parameters, mold is fed injection into, one-step solidification is carried out in one-step solidification stove, it is primary solid
It is as follows to change technological parameter：
Each stage curing temperature and time are followed successively by：（1）33~35 DEG C of initial temperature cures 1 hour,（2）It is warming up to 35~45
DEG C, cure 4.5 hours,（3）45~65 DEG C are warming up to, is cured 7 hours,（4）65~90 DEG C are warming up to, is cured 2 hours,（5）
90 DEG C of constant temperature cures 5 hours,（6）Temperature adjustment cures 5 points to 90~75 DEG C,（7）75 DEG C of constant temperature cures 2 hours.
C. postchannel process
（1）The eyeglass substrate that preceding road is trimmed carries out multiple-grooved ultrasonic cleaning, then by the eyeglass substrate after cleaning secondary solid
Change and carry out secondary curing in stove, technique is followed successively by（1）In the case where temperature is 110 DEG C~130 DEG C of Elevated Temperature Conditions, cure 1 hour,
（2）Under 130 DEG C of constant temperature, cure 3 hours,（3）30 DEG C are cooled to by 130 DEG C again, is cured 1 hour；
（2）It tests to the eyeglass after secondary curing, selects accepted lens substrate；To the further stiffened of substrate, plated film, examine
After qualification, become sold resin eyeglass.
A kind of high-intensity resin eyeglass of the present invention and preparation method thereof, technological design science, rationally can be produced in substrate
The hardness of enhancing product and the degree of cross linking of resin reaction in the process, improve hardness of the eyeglass after one-step solidification, it is anti-to improve eyeglass
Impact force, it is ensured that good quality of product, performance is stable, reliable, makes product meet FDA test requests, is fully able to normally enter
US and European market.
Description of the drawings
Fig. 1 is a kind of high-intensity resin eyeglass of the present invention and preparation method thereof processing step schematic block diagram；
The present invention will be further described below with reference to the drawings.
Specific implementation mode
FDA is known as " healthy patron saint " by American, and detection the harsh, rigorous of implementation procedure can be rated as the first in the world.
A kind of existing domestic diopter is more than the eyeglass of -6.00D, center thickness CT standards（QB2506-2001）：It is real not less than 1.0mm
Border center thickness is 1.2 ± 0.2mm, cannot still pass through FDA impact tests.It is analyzed by researching and developing, lens product was polymerizeing
The degree of cross linking and product hardness are inadequate in journey, therefore, the easily breakdown during FDA experiments.The present invention is once solid by eyeglass emphatically
The adjustment of solidification temperature and time when change, increases the constant temperature time of high temperature section, and polymerization process is improved when receiving eyeglass one-step solidification
The good result of the middle degree of cross linking.
Shown in Figure 1, high-intensity resin eyeglass of the present invention and preparation method thereof, step is specific as follows successively to be stated：
A. lens center thickness CT is designed
Lens center thickness increases, no doubt beneficial to improving eyeglass shock resistance, but lens thickness increases too much, influences eyeglass beauty
Degree and wear comfort.Lens center thickness CT designs, need to integrate various aspects factor, be determined.
Original parameter：
It is changed to：
B. one-step solidification technique
By lens center thickness CT technological parameters, mold is fed injection into, one-step solidification is carried out in one-step solidification stove, it is primary solid
It is as follows to change technological parameter：
Original parameter：
Each stage curing temperature and time are followed successively by：（1）33~35 DEG C of initial temperature cures 1 hour,（2）It is warming up to 35~45
DEG C, cure 6.5 hours,（3）45~65 DEG C are warming up to, is cured 7 hours,（4）65~90 DEG C are warming up to, is cured 2 hours,（5）
Temperature adjustment cures 1 hour to 90~75 DEG C,（6）75 DEG C of constant temperature（）, cure 2 hours.
It is changed to：
Each stage curing temperature and time are followed successively by：（1）33~35 DEG C of initial temperature cures 1 hour,（2）It is warming up to 35~45
DEG C, cure 4.5 hours,（3）45~65 DEG C are warming up to, is cured 7 hours,（4）65~90 DEG C are warming up to, is cured 2 hours,（5）
90 DEG C of constant temperature cures 5 hours,（6）Temperature adjustment cures 5 minutes to 90~75 DEG C,（7）75 DEG C of constant temperature cures 2 hours.
By adjusting crucial one-step solidification temperature and time parameter is changed, substantially increases and handed in eyeglass polymerization process
Connection degree makes eyeglass anti-impact force greatly improve, and meets FDA test requests.
C. postchannel process
The eyeglass substrate that preceding road is trimmed carries out multiple-grooved ultrasonic cleaning, then by the eyeglass substrate after cleaning in secondary curing
Secondary curing is carried out in stove, technique is followed successively by（1）In the case where temperature is 110 DEG C~130 DEG C of Elevated Temperature Conditions, cure 1 hour,（2）
Under 130 DEG C of constant temperature, cure 3 hours,（3）30 DEG C are cooled to by 130 DEG C again, is cured 1 hour；
It tests to the eyeglass after secondary curing, selects accepted lens substrate；To the further stiffened of substrate, plated film, examines and close
After lattice, become sold resin eyeglass.
Before and after process change, original shock resistance test data is as follows.
Test result before process change：
Test result after process change：
In addition to the above, the present invention can also have other embodiment, does not set out act one by one herein, it is every using equivalent replacement or
Equivalent transformation formed technical solution, belong to the present invention claims protection domain.
