Embodiment Construction

[0010] Polymer formulation:

[0011] Octyl methacrylate 80

[0012] Styrene 120

[0013] Toluene 60

[0014] Azobisisobutyronitrile 5

[0015] Aggregation operation:

[0016] 1. Mix octyl methacrylate, styrene and azobisisobutyronitrile well.

[0017] 2. Add the formula amount of toluene into the four-necked bottle.

[0018] 3. Flush the reaction bottle with nitrogen, and let it continue until the end of the reaction.

[0019] 4. After raising the temperature to 80-85°C, add the mixed reaction monomer 1 dropwise evenly, and finish adding within three hours.

[0020] 5. After continuing to react for three hours, cool down and discharge.

[0021] Preparation of rainproof agent:

[0022] 1. Dilute the polymer solution obtained above with 3000 grams of toluene until the solid content is between 5-8%.

[0023] 2. Dissolve 120 grams of simethicone in the solution obtained in 1.

Abstract

The invention relates to a preparation method of a rain vision used for auto windshield glass. The method synthesizes acrylic resin solution with good water repellency. By dissolving a certain amount of simethicone with water repellent function into polymer solution, the rain vision of the invention used for auto windshield glass which has good water repellency and adhesion performance is obtained.

Description

technical field [0001] The invention belongs to the field of fine chemicals and relates to a method for manufacturing a rainproof agent for automobile glass. Background technique [0002] When the car is driving in rainy days, the wiper needs to wipe water continuously. The non-stop swing of the wiper will interfere with the driver's sight, and because the wiper does not remove water cleanly, the transparency of the windshield is significantly reduced, which also affects the driver's sight, increasing the Difficulty driving safely. [0003] In order to solve this problem, people have developed some rainproof agents for automobile windshields, mostly obtained by dissolving simethicone oil with strong water repellency in organic solvents. Although it has a good waterproof effect, its adhesion is small, and it will lose its effect when it is washed by rain and cars, and its service life is very short. Contents of the invention [0004] The invention not only ensures that th...
