Benefits of technology

The technical effect of this patented method involves introducing certain materials like ceria or zirconia onto an oily substance called silicon dioxane (SiO2) for creating a special type of chemical that can be used with other coatings such as acrylics, epoxy resins, urethanes, etc., making them more durably resistant against damage from external factors like impact force.

Problems solved by technology

The technical problem addressed in this patented text relates how to create durable antireflective films on various types of substrate surfaces without compromising transparency due to reduced reflection coefficient caused by increased scattering from small particles like silica.

Embodiment 1

[0034] For the preparation of titanium sol, dissolve 24g of n-tetrabutyl titanate in 6.28g of isopropanol, stir well, and record it as solution A; dissolve 1.28g of water and 0.15g of hydrochloric acid in 15.71g of isopropanol, mix well, Record it as solution B; under the condition of stirring, pour solution B into A and react for 12 hours. In this way, a titanium sol with a molar ratio of titanium to water of 1:1 is obtained, and can be stored for a long time.

Embodiment 2

[0036] The experimental method is the same as in Example 1, except that 16 g of ethyl titanate is used instead of 24 g of n-tetrabutyl titanate to obtain a titanium sol with a molar ratio of titanate to water of 1:1, which can be stored for a long time.

Embodiment 3

[0037] Embodiment 3: the preparation method one of titanium, silicon blended sol

[0038] Dissolve 223.70g of n-tetrabutyl titanate in 87.85g of isopropanol and stir evenly; add 175.69g of isopropanol solution dissolved in 11.75g ​​of water and 1.12g of hydrochloric acid into the above solution and react for 10 hours; Add 119.58g gamma-(2,3-glycidyloxy) propyltrimethoxysilane, stir and make it mix evenly, add the 363.75g isopropanol solution that is dissolved with 13.73g water and 1.67g hydrochloric acid at last, continue reaction 10 Hour, add 4g sodium acetate and 2g polydimethylsiloxane therein, obtain homogeneous, stable transparent solution, wherein the mass percent composition of each component is: n-tetrabutyl titanate 22.26%; γ-(2, 3-glycidoxy)propyltrimethoxysilane 11.90%; water 2.54%; hydrochloric acid 0.28%; sodium acetate 0.4%; polydimethylsiloxane 0.2%; isopropanol 62.43%.
