Problems solved by technology

This type of anti-fog agent is simple to prepare, but due to the condensation of moisture on the glass surface, the surfactant is easy to lose, so the anti-fog durability is poor, and the general anti-fog duration is 2 to 7 days

Embodiment 1

[0032] Recipe screening:

[0033] The transmittance (transmittancy, T) and antifogging time (antifogging time, AT) are important indicators for evaluating the quality of polymer antifogging films, and there are many factors that affect them. Select the four main factors that have a greater impact on the evaluation indicators, and each Take 3 levels for each factor, see Table 1, press L 9 (3 4 ) to arrange orthogonal experiments. In order to reduce the experimental error, each group of experiments was randomly carried out 3 times, and the average value was taken for analysis, and the quality identification of the best prescription was carried out.

Abstract

The invention relates to the field of material chemistry and mainly provides a polymer type antifogging agent for an optical lens and a preparation method thereof. The technical scheme in the invention comprises the following steps: mixing 1-2 parts by weight of colorless transparent secoctylphenol polyoxyethylene ether liquid which is abbreviated to TX-10, 8-12 parts by weight of isopropanol, 28-32 parts by weight of anhydrous ethanol and 45-50 parts by weight of double distilled water so as to form 100mL of basic liquid; and then adding about 100 parts by weight of double distilled water in 2-6 parts by weight of weighed white sodium dodecyl benzene sulfonate solid powder which is abbreviated to SDBS so as to prepare a 4.0% aqueous solution serving as an additive, and evenly mixing the additive with the basic liquid in a volume ratio of 1:1 (100mL:100mL), so that the antifogging agent is obtained.

Description

technical field [0001] The invention relates to the field of material chemistry, and mainly relates to a polymer type optical lens antifogging agent and a preparation method thereof. Background technique [0002] When using glass and transparent plastic, if there is a certain temperature difference on both sides, the water vapor in the air will condense into small water droplets on the surface and form fog. The curvature radius of the small water droplets is different, and the diffuse reflection of light is also different. Significantly reduces the light transmittance of transparent materials, affects the line of sight, brings a lot of inconvenience, and even causes major losses. If the fogging problem can be solved by using an anti-fogging agent, the surface of the lens substrate (glass or transparent plastic) can be modified and decorated, thereby obtaining a good anti-fogging effect, which will bring huge economic benefits. [0003] There are mainly three anti-fog method...
