Problems solved by technology

In the use of automobiles, it is found that in the case of a large difference in humidity and temperature, the outer side of the car will peel off and the surface of the rearview mirror will form a fog layer, or when it rains, the rearview mirror cannot be seen clearly or the side glass is blurred, blurred glass The surface seriously affects the driver's line of sight and affects the safety of driving vehicles
[0003] To solve the above problems, glass heating or rearview mirror heating are generally adopted, but generally there is a certain hysteresis, and most vehicles do not have the above configuration

preparation example Construction

[0041] For the preparation process of the polymer, you can refer to the references for the preparation of silicone acrylic polymer emulsion, preferably "Synthesis and Particle Size Analysis of Silicone-Acrylic Polymer Emulsion", Zhang Qingxuan et al., Chemical Research and Application, Vol. 22 No. Phase 4, Section 1.2 Preparation.

[0042] (Low Molecular Weight Terminated Polydimethylsiloxane)

[0043] The low-molecular-weight hydroxyl-terminated polydimethylsiloxane of the present invention is not particularly limited, and common polydimethylsiloxanes containing terminal hydroxyl groups are suitable for use. Regarding the molecular weight, the molecular weight of the low molecular weight hydroxyl-terminated polydimethylsiloxane is preferably 500-3000, more preferably 1000-2000.

[0044] The preferred end group of the low-molecular-weight hydroxyl-terminated polydimethylsiloxane also contains an alkoxy group, which can improve the interaction with the silane structure in the ...

Several embodiments and comparative examples are given below, but the above-mentioned embodiments and comparative examples do not constitute a limitation to the protection scope of the claims, and any concept that does not violate the present invention falls within the protection scope of the present invention.

[0085] (Preparation of modified array carbon nanotubes)

preparation example 1

[0087] (1) Carbon nanotubes are grown on a quartz substrate to form an array of carbon nanotubes, which are crushed into particles of about 1 μm;

[0088] (2) Add 100 parts by weight of the particles obtained in step (1) to a 0.05M hydrofluoric acid solution, stir for 15 minutes, and dry;

[0089] (3) Add the product of step (2) to 1.5 parts by weight of an alcoholic aqueous solution containing aminosilane coupling agent A-1100, stir for about 1 hour, and wash with water;

[0090] (4) The product of step (3) was treated with 8 parts by weight of fluorine-containing silane coupling agent heptadecafluorodecyltrimethoxysilane for about 2 hours, and dried to obtain the modified carbon nanotube array A1.

Abstract

The invention relates to an ultraviolet protection hydrophobic coating agent. The ultraviolet protection hydrophobic coating agent comprises 20-30 parts of organic silicon acrylic polymer emulsion, 2-10 parts of low molecular weight terminal-hydroxyl polydimethylsiloxane, 2-5 parts of modified array carbon nano tube, 3-8 parts of hydrophobic titanium dioxide, 1-3 parts of a dispersant, 0-2 parts of a defoaming agent and 100-300 parts of distilled water in parts by weight; the modified array carbon nano tube and the hydrophobic titanium dioxide are obtained by being treated by using an amino silane coupling agent and a fluoro silane coupling agent; and effects of appropriate adhesive force and excellent hydrophobicity are finally realized.

Description

technical field [0001] The invention relates to the field of hydrophobic coating agents, in particular to the field of anti-ultraviolet hydrophobic coating agents with strong adhesion, and also relates to the preparation method and application field of the coating agent. Background technique [0002] With the popularization of automobiles in recent years, the number of automobiles has shown rapid growth, and the accompanying automobile peripheral products have become a popular direction. In the use of automobiles, it is found that in the case of a large difference in humidity and temperature, the outer side of the car will peel off and the surface of the rearview mirror will form a fog layer, or when it rains, the rearview mirror cannot be seen clearly or the side glass is blurred, blurred glass The surface seriously affects the driver's line of sight and affects the safety of driving vehicles. [0003] To solve the above problems, glass heating or rearview mirror heating a...
