Abstract
The invention discloses a sealant for a solar module. The sealant consists of 50 to 90 weight parts of polydimethylsiloxane, 20 to 50 weight parts of methyl triethoxysilane, 5 to 30 weight parts of flame retardant, 5 to 20 weight parts of filler and 5 to 20 weight parts of thixotropic agent. A preparation method for the sealant comprises the following steps of: mixing and stirring the polydimethylsiloxane and the methyl triethoxysilane for 10 to 30 minutes; and adding the flame retardant, the filler and the thixotropic agent, and stirring and mixing uniformly. The sealant is neutral, does not have toxicity, corrosion and environmental pollution basically, has the advantages of good constructability, high elasticity, high bonding strength, high insulativity, ageing, ultraviolet and radiation resistance and the like, and can meet performance requirements of sealing and packaging the solar module.
Description
Technical field
The present invention relates to a kind of special seal gum for solar cell assembly and preparation method thereof, specifically, relate to a kind of silicone sealant of modification, belong to the matrix material technical field.
Background technology
Solar energy power generating is meant and utilizes photovoltaic effect to make solar radiation can be transformed into electric energy.Face the dual restriction of the energy and environmental protection day by day along with the human economy and the Sustainable development of society; This generation mode more and more receives people's attention; Each country all actively gets involved, the preemption techniques commanding elevation, and China also classifies sun power as one of opera involving much singing and action of new forms of energy industry.Therefore, over nearly 20 years, the photovoltaic industry has experienced develop rapidly, and the kind of solar cell is on the increase, range of application is wide day by day, market scale also enlarges rapidly.The photovoltaic industry will continue rapid growth in several years of future.IEA makes multiple prediction to global photovoltaic industry development prospect, and the most conservative prediction is that the photovoltaic production capacity will quadruple to the year two thousand twenty.
Solar battery sheet is the core component of solar photovoltaic generation system.Because physics, chemical imperfections such as thin, crisp, easy oxidation that solar battery sheet self exists are exposed to and are easy to cause permanent damage under the natural condition such as air, rainwater, make solar electrical energy generation be difficult to large-scale application under abominable natural condition.Therefore, realize the industrial applications of solar electrical energy generation, just require it is carried out protective seal and encapsulation, thereby form solar module.This protective seal is a guardian technique realizing photovoltaic generation suitability for industrialized production and large-scale application with encapsulation.In sealer; Silicone sealant is because its superior high and low temperature resistance, weather resistance, good air-tightness and be easy to characteristic such as construction; Being specially adapted to the protective seal and the encapsulation of solar module, is one of international and domestic solar sealant Development Trend.
