Problems solved by technology

Double-glass modules are usually used for BIPV, that is, the front and back panels of the module are encapsulated with tempered glass to achieve a transparent effect, but the glass is heavy and not strong enough, fragile, and inconvenient to install
In addition, some solar modules installed on the top of some canopies, parking lots, roofs, airports, large squares and other buildings need to have high transparency so as not to affect indoor lighting, and at the same time, the load-bearing of the building should not be increased too much, which is Solar modules are required to have good light transmission and light weight. Traditional double-glass modules can meet the requirements of light transmission, but because of the glass backplane used for the backplane, they cannot meet the light weight conditions, and the strength is low and fragile
Although the existing components with polymer composite film as the backplane are light in weight, they cannot meet the requirement of transparency

Abstract

The invention provides a resin composition for a base material of photovoltaic backboard and a preparation method of a photovoltaic backboard. The resin composition comprises the following components in parts by weight: 40-60 parts of polysilsesquioxane resin, 40-60 parts of epoxy resin, 5-10 parts of curing agent, and 0.01-1 part of accelerant. The photovoltaic backboard takes the resin composition which contains polysilsesquioxane resin, the epoxy resin, the curing agent and the accelerant as the base materials, and takes glass fiber cloth as a reinforcing material, has excellent characteristics of light weight, high strength and good light transmission, and can be used for substituting the existing photovoltaic backboard.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic backplanes, in particular to a resin composition for a matrix material of a photovoltaic backplane and a preparation method for a photovoltaic backplane. Background technique [0002] Energy is the lifeblood of economic development. Due to the aggravation of environmental pollution and the gradual reduction of fossil energy such as coal, oil and natural gas, countries have successively vigorously developed various new energy technologies such as nuclear energy, wind energy, combustible ice, and hydrogen energy. Among the above energy sources, solar energy is highly sought after due to its various advantages such as cleanness, inexhaustibility, inexhaustibility, and convenient development and utilization. Especially after the nuclear leak crisis triggered by the great earthquake in Japan in 2011, countries have incorporated the development of solar energy into their national energy stra...
