Problems solved by technology

The above six methods all have certain shortcomings. For a tunnel without any decoration on the concrete, the inner wall of the tunnel will absorb light, resulting in insufficient lighting and affecting the driver's vision; some ordinary coatings have very little effect on improving the visibility in the tunnel, and The surface is easily polluted, and the surface is cracked and peeled off, which is difficult to clean and affects the effect of brightening; decorative materials are prone to reflection, glare, light shadows and other adverse phenomena, which affect the driver's vision and cause traffic safety hazards; and this A series of problems such as flammable, fragile, complex repair, high cost, and long construction period

preparation example Construction

[0045] The present invention also provides a method for preparing a super-amphiphobic self-cleaning and brightening composite coating, comprising the following steps:

[0046] S1: Add resin and additives into 20 parts of organic solvent, and stir at 200rpm;

[0047] S2: adding the reflective material to the stirring vessel in step S1 in three stages, and stirring for 10 minutes after each stage;

[0048] S3: carry out ultrasonic dispersion for 0.5h;

[0049] S4: adding a coupling agent and a fluorosilane agent, and performing ultrasonic dispersion for 1 hour to obtain a component A stock solution;

[0050] S5: The first component stock solution obtained in step S4 is placed in a constant temperature water bath at 50°C and stirred for 2 h to obtain the first component;

[0051] S6: Take the resin curing agent as the B component and stir and mix with the A component to obtain a composite coating.

Embodiment 1

[0053] Component A: Disperse 10 parts of epoxy resin in 20 parts of anhydrous ethanol solution, stir at 200 rpm for 10 minutes at 40 °C, then add 27 parts of glass microbead powder, continue stirring for 10 minutes, and then add 6 parts Pearlescent powder, continue to stir for 10min, add 2 parts of titanium dioxide, stir for 10min, ultrasonically disperse at 50 ° C for 0.5h, after the ultrasonic dispersion is completed, add 2 parts of coupling agent, 5 parts of ammonia water, 5 parts of ethyl orthosilicate, 0.5 Parts of perfluorodecyl triethoxysilane and 5 parts of deionized water were dispersed in ultrasonic waves at 50°C for 1 hour, and then placed in a constant temperature water bath at 50°C and stirred for 2 hours to obtain component A.

[0054] The composition of component B is 10 parts of resin curing agent.

Embodiment 2

[0056] Component A: Disperse 10 parts of epoxy resin in 20 parts of ethyl acetate solution, under the condition of rotating speed of 200rpm, mechanically stir at 20°C for 10min, then add 27 parts of glass microbead powder, continue stirring for 10min and then add 6 parts Pearlescent powder, continue to stir for 10min, add 2 parts of titanium dioxide, after stirring for 10min, ultrasonically disperse at 20°C for 0.5h, add 2 parts of coupling agent, 5 parts of ammonia water, 5 parts of ethyl orthosilicate, 0.5 parts of perfluoro Decyl triethoxysilane, 5 parts of deionized water, ultrasonically dispersed for 1 hour, placed in a constant temperature water bath at 20° C. and stirred for 2 hours to prepare component A.

[0057] The composition of component B is 10 parts of resin curing agent.

Abstract

The invention relates to the technical field of novel materials, in particular to a super-amphiphobic self-cleaning brightening composite coating and a preparation method thereof. The invention relates to a super-amphiphobic self-cleaning brightening composite coating which is composed of a component A and a component B. The component A comprises the following components in parts by mass: 10 parts of resin, 35-40 parts of a reflective material, 2-4 parts of a coupling agent, 0.5-1 part of a fluorosilane agent and 35-40 parts of an auxiliary agent; a component B: 10 parts of a curing agent; wherein the auxiliaries comprise a thixotropic agent, a dispersing agent and a defoaming agent. High hydrophobic, oleophobic, heat-resistant, cold-resistant, corrosion-resistant and weather-resistant effects are achieved; corrosion to the surface of a substrate material can be slowed down, the substrate is protected, and the coating has extremely high adhesive force and high wear resistance; the reflective rate and diffuse reflection can be effectively increased, a very strong brightening effect can be achieved, and people feel comfortable; the self-cleaning capability is realized; the scratch, friction, pressure and deformation can be effectively resisted, and the impact damage of most objects can be effectively resisted.

Description

technical field [0001] The invention relates to the technical field of novel materials, in particular to a super-amphiphobic self-cleaning and brightening composite coating and a preparation method thereof. Background technique [0002] my country is a mountainous country, and about 75% of the country is mountainous. Tunnels must be used in mountain highway construction. However, in the process of large-scale construction, domestic tunnel construction also exposes some deficiencies. In the lighting of tunnels, it is often faced with the process from bright to dark to bright, which will affect the driver's vision and lead to many accidents. The extensive use of lighting equipment will greatly increase the operating cost. Simple use of lighting and reflective materials, the lighting effect is not good, affecting the vision of driving. [0003] Therefore, in order to solve the existing problems and reduce operating costs, it is very necessary to develop a self-cleaning and bri...
