    The special epoxy resin for wind turbine blades, that is, the epoxy resin used in the manufacture of wind turbine blades, is made by deep processing of basic epoxy resin.
    It has good wettability to glass fiber and carbon fiber, and has excellent process operability and heat resistance.
    Excellent mechanical properties, after being compounded with reinforced materials, it has excellent mechanical properties and fatigue resistance
    .
    ? Classification of special epoxy resin for wind power blades? According to different uses, special epoxy resin for wind power blades can be divided into wind power blade vacuum infusion resin, wind power blade hand lay-up resin, wind power blade epoxy structural adhesive, and wind power blade mold resin
    .
    ? 1.
    Wind power blade vacuum infusion epoxy resin? Wind power blade vacuum infusion epoxy resin is suitable for vacuum infusion process to produce large composite parts and products, especially suitable for the infusion production of megawatt wind energy generator blades;? 2.
    Wind power blade hand lay-up epoxy resin is suitable? Wind power blade hand lay-up epoxy resin is suitable for the production and repair of composite parts by hand lay-up process, such as encapsulation and repair of megawatt wind power wind turbine blades;? 3.
    Wind power Blade epoxy resin structural adhesive? Wind turbine blade epoxy resin structural adhesive is suitable for mutual bonding between resin-based composite materials and metal parts, and excellent bonding performance can be obtained even when the bonding gap is large;? 4.
    Wind turbine blade mold resin? Wind turbine blade mold resin can effectively shorten the curing process time and improve production efficiency.
    It can also be used with processes such as infusion or RTM, and provides good mechanical properties and toughness, especially suitable for use in large-scale component structures
    .
    In 2020, the domestic demand for special epoxy resin for wind turbine blades exceeds 300,000 tons.
    The special epoxy resin for wind turbine blades is exclusively used in the field of wind power, and the demand is greatly affected by the installed capacity of downstream wind power
    .
    On January 29, 2021, the National Energy Administration held an online press conference for the first quarter to announce the winter energy supply status, the development of renewable energy in 2020, and the reliability of power supply for users of power supply companies in 50 major cities across the country in the fourth quarter of 2020 indicators
    .
    ? The press conference pointed out that in 2020, renewable energy will continue to maintain high-quality development, the installed capacity will be steadily expanded, the power generation will continue to grow, and the high utilization rate will be maintained..
    ? In 2020, 71.
    67 million kilowatts of grid-connected wind power will be added nationwide, including 68.
    61 million kilowatts of onshore wind power and 3.
    06 million kilowatts of offshore wind power
    .
    In terms of the distribution of new installed capacity, the central and eastern and southern regions accounted for about 40%, and the "Three Norths" region accounted for 60%
    .
    By the end of 2020, the cumulative installed capacity of wind power nationwide was 281 million kilowatts, of which the cumulative installed capacity of onshore wind power was 271 million kilowatts, and the cumulative installed capacity of offshore wind power was approximately 9 million kilowatts
    .
    ? The national wind power installed capacity statistics from 2016 to 2020 are as follows:?? Data source: National Energy Administration, epoxy resin exchange and transaction arrangement? We have always been concerned about the consumption of epoxy resin by wind power installed capacity in 2020.
    With authoritative data, calculations can be carried out
    .
    ? According to the data provided by relevant companies: 1GW of wind power consumes about 6000 tons of formula materials, and 1 ton of formula materials contains 65% pure epoxy resin
    .
    In this way, 1GW blades consume about 6000T×0.
    65=3900T epoxy resin; 1GW wind turbine blades consume about 700 tons of structural adhesive.
    If one ton of structural adhesive consumes 50% pure epoxy resin, 1GW blades need to consume 700T×0.
    50=350T epoxy resin.

    .
    Theoretically, 1GW blade consumes 3900+350=4250 tons of LER
    .
    ? An additional 71.
    67GW will be added for the whole year of 2020, and 4250T×71.
    67=304597.
    50T epoxy resin will be consumed throughout the year.
    If the amount of epoxy primer coating used in towers, etc.
    is added, it is estimated that the wind power system will consume epoxy resin throughout the year.
    It can reach about 320,000 tons
    .
    It can be seen that the demand for epoxy resin for wind turbine blades in China in 2020 has exceeded 300,000 tons, and it is the only country in the world with a demand exceeding 100,000 tons.
    Both the United States and Europe have more than 50,000 tons of epoxy resin for wind turbine blades.
    Demand for epoxy resin products for wind turbine blades
    .
    Outlook? Following Guangdong Province, Jiangsu Province has also launched a 100 billion 8GW offshore wind power plan, which will provide strong support for the 14th Five-Year Plan for offshore wind power market demand, and clear the valuation barriers of leading offshore wind power companies.
    The global offshore wind power market has 10 years of experience.
    With a five-fold growth gold track, domestic leading companies are expected to successfully open the international market during the 14th Five-Year Plan period with their technological accumulation and market foundation comparable to those of the international community
    .
    In the future, with the development of offshore wind power, the epoxy resin industry for wind turbine blades will gradually shift to the research and development of offshore wind turbine blade resins.
    The corresponding products suitable for the production of offshore wind turbine blades and molds will also develop rapidly.
    The market prospect is very broad
