[0031] Mix graphene oxide and water in a beaker at a mass ratio of 1:200, and ultrasonically disperse for 40 minutes at a frequency of 55 kHz to obtain a graphene oxide dispersion. The graphene oxide dispersion and hydrazine hydrate are mixed at a mass ratio of 100 : 1 mixed in a flask, and adding 0.08 times the weight of the graphene oxide dispersion to the flask with 28% ammonia water, at a temperature of 90°C and a rotating speed of 400r / min, stirring and reacting for 180min, then filtering , to obtain a filter cake, the filter cake was vacuum-dried at a temperature of 65°C for 5 hours to obtain pretreated graphene, and the pretreated graphene and ethanol were mixed in a three-necked flask at a mass ratio of 1:100, and poured into a three-necked Sodium hydroxide with 3 times the mass of pretreated graphene and cationic surfactant with 2 times the mass of pretreated graphene were added to the flask. Under the condition of frequency of 55kHz, after ultrasonic dispersion for 40...

Abstract

The invention discloses waterproof solar energy back plate glue, and belongs to the technical field of a high polymer material. In parts by weight, 40 to 50 parts of epoxy resin, 15 to 20 parts of ethylene-vinyl acetate copolymers, 2 to 5 parts of turpentine, 8 to 16 parts of phosphorus oxychloride, 15 to 22 parts of modified graphene, 8 to 15 parts of polyaspartic ester, 5 to 8 parts of epoxidized soybean oil, 5 to 12 parts of isocyanates, 8 to 15 parts of carbonate and 60 to 80 parts of solvents are sequentially weighed; the epoxy resin and solvents are mixed in a stirring machine; the ethylene-vinyl acetate copolymers, turpentine, phosphorus oxychloride, modified graphene, polyaspartic ester, epoxidized soybean oil, isocyanates and carbonate are added into the stirring machine; stirringand mixing are performed for 30 to 60 min under the conditions of the temperature being 20 to 30 DEG C and the rotating speed being 300 to 400 r / min to obtain the waterproof solar energy back plate glue. The solar energy back plate glue prepared by the technical scheme has the characteristic of excellent water-resistant performance and bonding intensity.

Description

technical field [0001] The invention discloses a waterproof solar backboard adhesive, which belongs to the technical field of polymer materials. Background technique [0002] Due to the gradual reduction of fossil energy and various pollution problems during its use, countries are strengthening the development and utilization of clean energy such as solar energy. Solar panels are commonly used in solar equipment at present, which is an important device for converting solar energy into electrical energy. The service life of such products is generally designed to be more than 25a. To ensure such a long service life of the product, it is necessary to strictly control the quality of each component, and the role of the solar cell backsheet in these components cannot be underestimated. The solar backsheet is located on the back of the solar cell, which protects and supports the cell. The use environment requires it to have properties such as insulation, weather resistance, and wa...
