Embodiment 1

[0020] Step 1: After irradiating cyclotetramethicone with 50 rem gamma rays for 10 minutes, the modified cyclotetramethicone was obtained. At 60°C, 15 parts of modified cyclotetramethicone base siloxane and 12 parts of polyether-polysiloxane copolymers were stirred for 30 minutes to obtain a superhydrophobic medium;

[0021] Step 2: According to the weight ratio of 1.5:2:0.5:1 BiO 3 、TiO 2 , ZrO 2 and MgF 2 Placed in a nitrogen environment with a pressure of 2 Pa, calcined at 400°C for 2 hours, pulverized, and passed through a 300-mesh sieve to obtain an optical anti-reflection agent;

[0022] Step 3: At 40°C, disperse the superhydrophobic medium in 5 parts of tetrahydrofuran, and after ultrasonication for 20 minutes, mix evenly with 8 parts of optical anti-reflection agent and 2 parts of polyacrylamide to obtain a waterproof glass coating solution.

Embodiment 2

[0024] Step 1: After irradiating cyclotetramethicone with 100 rem gamma rays for 12 minutes, the modified cyclotetramethicone was obtained. At 70°C, 16 parts of the modified cyclotetramethicone base siloxane and 13 parts of polyether-polysiloxane copolymer were stirred for 35min to obtain a superhydrophobic medium;

[0025] Step 2: According to the weight ratio of 1.75:2.5:0.75:1.5 BiO 3 、TiO 2 , ZrO 2 and MgF 2 Placed in a nitrogen environment with a pressure of 3 Pa, calcined at 450°C for 2.5 hours, pulverized, and passed through a 350-mesh sieve to obtain an optical anti-reflection agent;

[0026] Step 3: At 45°C, disperse the super-hydrophobic medium in 7 parts of tetrahydrofuran, and after ultrasonication for 25 minutes, mix evenly with 10 parts of optical anti-reflection agent and 3 parts of sodium dodecylbenzenesulfonate to obtain a waterproof glass coating solution.

Embodiment 3

[0028] Step 1: After irradiating cyclotetramethicone with 150 rem gamma rays for 15 minutes, the modified cyclotetramethicone was obtained. At 80°C, 18 parts of the modified cyclotetramethicone base siloxane and 15 parts of polyether-polysiloxane copolymer were stirred for 40 minutes to obtain a superhydrophobic medium;

[0029] Step 2: Mix BiO with a weight ratio of 2:3:1:2 3 、TiO 2 , ZrO 2 and MgF 2 Placed in a nitrogen environment with a pressure of 4 Pa, calcined at 500°C for 3 hours, pulverized, and passed through a 400-mesh sieve to obtain an optical anti-reflection agent;

[0030] Step 3: Disperse the super-hydrophobic medium in 10 parts of tetrahydrofuran at 50°C, and after ultrasonication for 30 minutes, mix evenly with 12 parts of optical anti-reflection agent and 4 parts of sodium oleoyloxyethanesulfonate to obtain a waterproof glass coating solution.

Abstract

The invention discloses a waterproof glass coating solution and a preparation process thereof. The waterproof glass coating solution comprises 15-18 parts of modified cyclotetrapolydimethylsiloxane and 12-15 parts of polyether-polysiloxane Copolymer, 2-4 parts of anionic surfactant, 5-10 parts of tetrahydrofuran and 8-12 parts of light enhancer. The modified cyclotetrapolydimethylsiloxane is obtained by irradiating cyclotetrapolydimethylsiloxane with 50-150 rem gamma rays. The invention has extremely strong drainage performance, reduces the incidence of traffic accidents in rainy days, improves the fatigue resistance of the glass, strengthens the anti-fouling ability and self-cleaning ability of the glass, and can increase the lighting rate of the glass and reduce the permeability of ultraviolet rays.

Description

technical field [0001] The invention belongs to the field of glass coating, and in particular relates to a waterproof glass coating solution and a preparation process thereof. Background technique [0002] According to statistics from the traffic police department, the incidence of traffic accidents in rainy days is 13 times that of sunny days. The most direct reason is that rainwater sticks to the glass of the car, which makes the driver's vision blurred, which in turn makes traffic accidents happen frequently in rainy days. Most of the coating solutions in the prior art solve the problem of light transmittance of glass, but there is no precedent for solving the problem of waterproofing. The patent application number is CN101830640A, through SiO 2 , MgF 2 h 4 , ZnO and Al 2 o 3 A coating solution mixed with a water-alcohol solvent can increase the transmittance of sunlight, thereby improving the solar energy conversion efficiency, but the water-alcohol solvent in the c...
