Abstract

The invention discloses a preparation method of solar concentrating resin. According to the method, bi-phenolic methane and dimethoxypropane are dissolved in the molar ratio being 1:(8-12), meanwhile, 8-12 ml of a catalyst is added, and the mixture is heated to the temperature of 65-70 DEG C and has a reaction at the temperature for 28-32 min; the mixture is cooled to the temperature of 60 DEG C, a first part of liquid caustic soda is slowly and dropwise added, the mixture is heated, and the reaction temperature is kept to range from 65 DEG C to 70 DEG C, reflux is performed for 2 h, the dimethoxypropane which does not react is recovered in a reduced pressure manner, the mixture is cooled to the temperature below 65 DEG C, 55-65 ml of a solvent is added, meanwhile, a second part of liquid caustic soda is dropwise added, reflux is performed for 2 h, a solvent solution turns yellow and is cooled and washed with hot water, a water layer is separated until the solvent solution is transparent, the solvent is evaporated out, and the resin is prepared. The resin has the characteristics of high concentrating property, high precision, good weather resistance, low cost and the like and can comprehensively improve the efficiency and the quality of a solar concentrating power generation system in the aspects of the optical effect, the weather resistance and the technology.
