preparation example Construction

[0058] The preparation method of the pore-forming agent is as follows: add a certain amount of mixed solvent into a four-necked bottle equipped with a thermometer, an electric stirrer, a condenser tube and a constant pressure funnel, start stirring and heating; when the temperature reaches the preset reaction temperature, , add a certain stoichiometric initiator; after the temperature stabilizes, start adding the pre-weighed mixed monomer, complete the addition of the mixed monomer within the predetermined time, and carry out the heat preservation reaction; after the reaction is completed, cool down to 40 ℃ ~ 50 ℃, add additives to neutralize, adjust the pH value to a suitable range, filter and discharge to obtain a pore-forming agent.

[0059] Specifically, the reaction temperature is 60°C-135°C; the time for adding the mixed monomer is 2-6 hours; the reaction time is 4-16 hours; the pH range of the pore-forming agent is 4-10; the auxiliary agent used for neutralization includ...

Embodiment 1

[0076] Mix 20g of the pore-forming agent of the pore-forming agent synthesis example 1 and 40g of the modified hydroxysilicone oil sol of the synthesis example 3 of the modified hydroxysilicone oil sol, add 0.4g of KH560, stir evenly, heat to 90°C, and keep warm for 2 hour, then cooled to room temperature, added 340g isopropanol, and the solution was diluted to a solid content of 3%, thereby preparing a stable coating solution.

Embodiment 2

[0078] Mix 40g of the pore-forming agent of the pore-forming agent synthesis example 3 with 60g of the modified hydroxysilicone oil sol of the synthesis example 2 of the modified hydroxysilicone oil sol, add 1g of KH550, stir evenly, heat to 50°C, and keep it warm for 8 hours, then After cooling to room temperature, 300 g of isopropanol was added to dilute the solution to a solid content of 4%, thereby preparing a stable coating solution.

Abstract

The invention discloses a silicone oil modified anti-dazzle anti-reflection coating solution, a preparation method and application, and relates to the technical field of solar glass. The silicone oil modified anti-dazzle anti-reflection coating solution provided by the invention contains modified hydroxyl silicone oil sol, a pore forming agent, a silane coupling agent and a diluent. After the surface of glass is coated to form a film through a roller coating coating process, particles in the modified hydroxyl silicone oil sol can form a micro-convex structure in a film layer, so that the glass has an anti-dazzle effect. The coating solution is prepared by adopting a chemical synthesis method, is suitable for a roll coating process with the highest film coating efficiency, is simple to process and does not need to adopt an atomization spraying mode; and multiple layers of films do not need to be additionally plated, so that the production efficiency can be improved and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of solar glass, in particular to a silicone oil-modified anti-glare and anti-reflection coating solution, a preparation method and an application. Background technique [0002] The original sheet of photovoltaic glass is coated with one or more layers of anti-reflection film (AR film) suede tempered glass, which is used as cover glass on photovoltaic modules. glare effect. [0003] With the popularization and application of photovoltaic modules, photovoltaic modules have gradually entered urban curtain walls, roofs and private applications from power stations in mountains, seaside and deserts. However, existing photovoltaic modules have disadvantages such as strong reflection, glare and light pollution. The application of photovoltaic modules in the city will be limited, and photovoltaic module manufacturers will also put forward higher requirements for photovoltaic modules in areas such as curtain walls, r...
