Uncured rubber asphalt waterproof coating, preparation method thereof and waterproof reflecting film

Abstract

The invention discloses an uncured rubber asphalt waterproof coating, a preparation method thereof and a waterproof reflecting film. The uncured rubber asphalt waterproof coating comprises the following raw materials in parts by mass: 30-70 parts of petroleum asphalt, 3-10 parts of a tackifier, 10-20 parts of a softening agent, 10-15 parts of rubber powder, 0.5-2 parts of an anionic dispersant, 10-20 parts of a thickening agent and 0.1-2 parts of a catalyst. The waterproof reflecting film is prepared from the coating. The petroleum asphalt is used as the main material of the uncured rubber asphalt waterproof coating, and is added with other additives which are in cross-linking reaction with the petroleum asphalt, thus, the coating has high chemical stability, has certain creep property, seals cracks and capillary pores of a base layer, can adapt to a complicated construction operation surface, and has good weather fastness, the characters of sticky rubber are always maintained, the capillary pores and the cracks of the base layer can be sealed well, the problems that cracking stress of the base layer is transmitted to a waterproof layer, thus, the waterproof layer is broken and isfatigue under flexing or is aged ahead of time due to the fact that the waterproof layer is in a high-stress state are solved, and the construction difficulty is simplified.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a non-cured rubber asphalt waterproof paint, a preparation method thereof, and a waterproof reflective film. Background technique [0002] With the continuous development of photovoltaic technology, photovoltaic modules have been widely used in many industries such as construction engineering. Double-glass photovoltaic modules are a relatively common photovoltaic module. Compared with conventional photovoltaic modules, crystalline silicon double-glass modules are not only safer High, and while providing clean and environmentally friendly power, it solves the problems of material aging and power attenuation caused by outdoor degradation of traditional backplanes. With the continuous improvement of use requirements, its use performance has also attracted increasing attention. The double-glass double-sided power generation module mainly receives the sunlight that passes...

Problems solved by technology

[0003] (1) The EVA film close to the rear glass uses high-cut EVA film or porcelain white EVA film as the reflective film, which increases the reflection of transmitted light energy and increases the power generation of the double-glass module, but increases the manufacturing process. , to increase production costs;

[0004] (2) By adding aluminum foil in front of the rear glass of the double-glass module, because the aluminum foil has high light reflection, it increases the reflection of the transmitted light energy, which significantly improves the power generation of the double-glass module, but the production process of the module It is more complicated and increases the cost of double-glass bifacial power generation components;

[0005] (3) Apply a white coating on the contact surface between the lower glass and the lower packaging material, and use the white coating to increase the absorption and reflection of light inside the module to increase the use of light, thereby increasing the power generation of the double-glass module, but Among them, the white coating in the cell area has no gain effect on increasing the light absorption inside the module, so it has little effect on improving the power generation of the double-glass double-sided power generation module and increases the cost of the module;

[0006] (4) By setting the gap between the front cells of the rear cover glass and the gap between the battery strings composed of multiple cells, the gap area has a reflective structure, which is used to reflect the sunlight irradiated into the gap area Oriented reflection to the battery sheet increases the absorption of internally reflected light by the double-glass module, thereby improving the solar light absorption efficiency of the double-glass module and increasing the output power of the double-glass double-sided power generation module, but complicating the production process , increasing manufacturing costs
