Photoelectric building material and preparation method thereof

Abstract

The invention provides a photoelectric building material and a preparation method thereof. A packaging material in the photoelectric building material comprises 30-50% of a fiber material, 35-50% of resin and 15-20% of a curing agent. A preparation method of the packaging material comprises the following steps: premixing the resin with the curing agent, coating a fiber cloth formed by braiding thefiber material with the mixture, pre-bonding the mixture with the fiber cloth through pressurizing and heating, and cutting the pre-bonded fiber cloth to produce the packaging material. The preparation method of the photovoltaic building material comprises the following steps: (1) sequentially stacking a fluorine plastic film, a packaging material, EVA, a solar cell, second packaging material anda green building material, and carrying out lamination and cooling to obtain the photoelectric building material; and (2) sequentially stacking the fluorine plastic film, the first packaging material, EVA, the solar cell, the second packaging material and a backing plate, carrying out lamination and cooling to obtain a laminated part, uniformly spreading an adhesive or a hot-melt adhesive film onthe surface of the green building material, pasting the laminated part, and carrying out full curing to obtain the photovoltaic building material.

Description

technical field [0001] The invention relates to a building material, in particular to a photoelectric building material and a preparation method thereof, and belongs to the technical fields of new energy power generation, photovoltaic application and green building materials. Background technique [0002] With the increasing pressure of environmental protection, green development has increasingly become the theme of the world economy. my country has raised the construction of ecological civilization and green development to unprecedented heights, and building energy conservation is one of the important measures to promote green development. [0003] Since the reform and opening up, my country's infrastructure construction and real estate investment have continued to grow, and the proportion of building energy consumption in the total energy consumption of society has been rising steadily. According to authoritative data, at the end of the 1970s, my country's building energy...

Problems solved by technology

Moreover, BAPV will increase the building load and affect the overall effect of the building

In addition, for the surface of buildings, BAPV also has the problem of repeated construction, which seriously wastes building materials.
