Embodiment 1

[0035] Solar photovoltaic module sealant, which is made of the following raw materials in weight percentage: polyisobutylene 50%, light calcium carbonate 30%, heavy calcium carbonate 10%, carbon five resin 3%, butyl rubber 6.7%, anti-oxidation Agent PL-100.3%.

[0036] The synthetic method of solar photovoltaic module sealant comprises the following steps: get 50kg of polyisobutylene with a molecular weight of 3W and put it into a vacuum kneader, heat up to 150 degrees; stir under 0.09Mpa vacuum condition for 0.5 hour; then add 3kg of carbon five resin Stir with 0.3kg of antioxidant PL-10 for 0.3 hours; then add 6.7kg of butyl rubber and stir for 0.3 hours; finally drop in 30kg of light calcium carbonate and 10kg of heavy calcium carbonate; mix the above under 0.09Mpa vacuum conditions Stir and knead for 1 hour to obtain the finished product. The performance test of the finished product is as follows:

Abstract

The invention relates to a seal gum, in particular to a seal gum for binding and sealing a solar energy photovoltaic component or a solar lamp. The invention provides an improvement of a solar energy photovoltaic component seal gum. The seal gum is characterized by good sealing performance, fast curing speed, high weather resistance and convenient operation. The other aim of the invention is to provide a synthesis method of the solar energy photovoltaic component seal gum. The synthesis method is characterized by simple technological process and high yield. The technical scheme provided by the invention is that the solar energy photovoltaic component seal gum is characterized in that the seal gum is prepared from the following raw materials by weight percent: 50-75% of polyisobutylene, 10-30% of light calcium carbonate, 5-10% of heavy calcium carbonate, 2-5% of C5 resin, 5-10% of butyl rubber and 0.1-0.3% of antioxidant.

Description

technical field [0001] The invention relates to a sealant, in particular to a sealant used for bonding and sealing solar battery modules or solar lamps. Background technique [0002] Solar energy is one of the green energy sources mainly used in the world at present. Solar panels are the only way to convert sunlight into electricity. Solar photovoltaic module sealant is required for the sealing of the frame of solar cell modules, the sealing of solar lamps, the bonding and sealing of the outer frame of photovoltaic solar panel modules and junction boxes, and some places with high requirements for weather resistance and air tightness. [0003] At present, the common one-component silicone solar photovoltaic sealant is used in the market; the main disadvantage of this glue is that it takes a certain period of time (about 24 hours) to cure, the sealing performance is not perfect, and it has a certain corrosion effect on metals. Contents of the invention [0004] The technic...
