Since the adhesive glue can have the same kind of connection or dissimilar material joints without stress concentration, high bonding strength, easy to realize the advantages of automation compounds, widely used in various fields of national economy, has become a national economic development can not or lack of chemicals. In the new energy field, in recent years, countries around the world are seeking to develop wind power and solar power, China is no exception.

    In wind power, for example, the annual average growth rate of China's new wind power installed capacity in 11th Five-Year reached 95.5%, the growth rate is far higher than the global average. Expected by 2020, China's wind power cumulative installed capacity will reach KW. This provides a broad market space for the fan blade with epoxy structural adhesive. According to relevant statistics, in the wind power generation industry, epoxy resin structural adhesive is mainly used for wind chessboard ring flounder plating carry flounder plating Chi Mao mushroom dry flinch Mei see Jia Tiao, 0.35 tons. In 2020, China's total wind power installed capacity reached 2.3 KW billion to calculate the demand of epoxy structural adhesive will reach 13.1 tons.

    Solar as a renewable energy, clean, safe and reliable, the construction of power stations on the geographical location of the requirements is not high, and the required time and cost are relatively low, in the future development has good prospects. At present, all the countries in the world are developing the solar energy. Over the past 5 years the global solar cell production average annual growth rate of 50-60%, the average growth rate in the next few years will remain at 20-25%.

    According to the European Union Research Center's forecast, by 2030 solar power generation in the world's total power supply will reach more than 10%. Solar power in China is almost starting from 2000, but development speed is very fast, 2000 to 2013 the average growth rate by 143.6 percent, 2013 solar cell production reached 4200 MW and become the largest country in the world solar cell production, accounting for about 50% of the total world output.

    The solar cell is mainly adhesive epoxy structural adhesive, EVA glue film, silicone rubber. Epoxy structural adhesive used for cutting of silicon solar cells, the intensity, stress and technical requirements is very high; EVA film used for assembling solar modules, the glass panel with silicon and monocrystalline silicon solar cells backplane or glass panel and the back film bonding of thin film batteries assembled together, the strength and transparency waterproof, weather resistance, steam penetration requirements of glass panels and back film adhesive high battery assembled together, the strength, transparency, weatherability, water vapor permeability requirements; silicone rubber used for solar module frame seal and connection box sealing, the sealing requirements of weather resistance and water vapor permeability of the frame, used for wiring box encapsulating electrical properties and good thermal conductivity requirements.
