NOVELTY - Solar photovoltaic glass super-hydrophobic self-cleaning material comprises 30-200 pts. wt. solution A, 10-40 pts. wt. polyurethane, 10-30 pts. wt. acrylic resin, 2-5 pts. wt. gas phase silicon dioxide, 2-3 pts. wt. tetragonal lanthanum oxide and 20- 30 pts. wt. octadecyltrichlorosilane. USE - The super hydrophobic self-cleaning material is useful for solar photovoltaic glass. ADVANTAGE - The material improves the problem that the surface of the photovoltaic glass is easy to accumulate dirt. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing super hydrophobic self-cleaning material comprising (i) mixing tetragonal lanthanum oxide with part of the solution A, controlling the temperature at 45-50 degrees C, heating in a water bath, and controlling speed at 250-300 revolutions/minutes and stirring for 25-30 minutes, completing stirring, adding octadecyltrichlorosilane and reacting for 6-8 hours, completing reaction, filtering product and washing, and controlling temperature at 80-100 degrees C and drying for 5-10 minutes to obtain the modified tetragonal lanthanum oxide; (ii) mixing the fumed silica with part of the solution A, heating temperature to 65-70 degrees C for heating in a water bath, and controlling the rotation speed to 250-300 revolutions/minutes and stirring for 25-30 minutes, stirring, adding octadecyltrichlorosilane and reacting for 6.5-7 hours, completing reaction, filtering product and washing, and controlling temperature at 80-100 degrees C and drying for 5-10 minutes to obtain modified silica, (iii) mixing polyurethane and acrylic resin, modified tetragonal lanthanum oxide, modified silica, and solution A into the mixture of polyurethane and acrylic resin, grounding for 2-6 hours, and ultrasonically dispersing for 20-30 minutes
