Embodiment Construction

[0015] The invention provides a kind of preparation method of waterborne epoxy paint, and its raw material comprises the following components in parts by weight:

[0016] 55-85 parts of SiO2, 0.5-2 parts of Al2O3, 3.5-11 parts of CaO, 13-19 parts of alkali metal oxides, 0-0.01 parts of iron oxides and 0.01-2 parts of tungsten oxide. The preparation method includes the following steps steps:

[0017] In the first step, SiO2, Al2O3, CaO, alkali metal oxides, iron oxides and tungsten oxide are mixed;

[0018] In the second step, melting is carried out in sequence, and the prepared raw materials are heated at high temperature to form a uniform glass liquid without bubbles;

[0019] The third step, forming, transforms the molten glass into a solid product with a fixed shape, and the glass changes from a viscous liquid state to a plastic state, and then into a brittle solid state;

[0020] The fourth step, annealing, uses a continuous annealing furnace to eliminate or reduce the t...

Abstract

The invention relates to the field of glass matching material compositions, specifically to a preparation method of a photovoltaic glass material. The method comprises the following steps: mixing SiO2, Al2O3, CaO, an alkali metal oxide, an iron oxide and tungsten oxide, sequentially melting, and carrying out high-temperature heating on the prepared raw materials to form uniform bubble-free moltenglass; converting the molten glass into a solid product with a fixed shape, wherein the glass is converted into a plastic state from a viscous liquid state and then converted into a brittle solid state; and finally eliminating or reducing the thermal stress in the glass to an allowable value through four stages of heating, heat preservation, slow cooling and rapid cooling by using a continuous annealing kiln. The photovoltaic glass material prepared through the preparation method is beneficial to photoelectric conversion of a battery, and the photovoltaic power generation capacity is improved.

Description

technical field [0001] The invention relates to the field of glass batch composition, in particular to a method for preparing a photovoltaic glass material. Background technique [0002] Common photovoltaic modules include photovoltaic glass cover plates, ethylene-vinyl acetate copolymer resin films, crystalline silicon cells and backplanes. Photovoltaic modules are the core part of photovoltaic power generation systems, and their function is to convert solar energy into electrical energy. The above-mentioned photovoltaic glass cover plate, ethylene-vinyl acetate copolymer resin film and back plate all have their specific functions to ensure that the crystalline silicon battery has a relatively long service life while utilizing solar energy efficiently. Among them, the photovoltaic glass cover plate is located on the outermost layer of the front of the photovoltaic module, and in the outdoor environment, it directly receives sunlight. The photovoltaic glass cover uses its ...
