Problems solved by technology

[0002] The traditional flux for solar modules is only to remove the oxide layer on the ribbon, so that the ribbon and the cell are firmly welded, and has no other functions
During the stringing process of the resin-based photovoltaic flux, a large amount of smoke will be produced during the high-temperature soldering process at 220°C, which not only pollutes the environment, but also has a large resistance after the high-temperature volatilization of the residual substance, which will affect the series connection of the cells. Conductivity, which affects the power generation of the entire assembly

Embodiment 1

[0019] Embodiment 1 soldering flux is made up of the raw material of following percentage by weight

[0020]

[0021] Preparation method: Weigh each component according to the weight percentage for later use, first pour the weighed anhydrous ethanol, propylene glycol butyl ether, and isopropanol into a glass reactor, and set the heating temperature of the reactor between 40-60°C Stir for 10 minutes, add the weighed succinic acid, adipic acid, and sebacic acid after they are fully uniform, and stir for 60 minutes. After fully dissolving, cool the temperature of the reactor to room temperature 25°C and add nano silicon The sol and nano-zinc oxide were weighed and packaged with a 300-mesh filter after stirring for 30 minutes.

Embodiment 2

[0022] Embodiment 2. Flux is made up of the raw material of following percentage by weight

[0023]

[0024] Preparation method: Weigh each component according to the weight percentage for later use, first pour the weighed isopropanol and propylene glycol methyl ether into a glass reactor, set the heating temperature of the reactor between 40-60°C, and stir for 10 After fully uniform, add the weighed adipic acid, citric acid, and itaconic acid, and stir for 60 minutes. After fully dissolving, lower the temperature of the reaction kettle to room temperature 25°C and add nano-silica sol and nano-oxidized Tin, after stirring for 30 minutes, weigh and pack with a 300-mesh filter.

Embodiment 3

[0025] Embodiment 3. Soldering flux is made up of the raw material of following percentage by weight

[0026]

[0027] Preparation method: Weigh each component according to the weight percentage for later use, first pour the weighed anhydrous ethanol and propylene glycol butyl ether ether into a glass reactor, set the heating temperature of the reactor between 40-60°C, and stir After 10 minutes, add the weighed succinic acid and suberic acid after being fully uniform, and stir for 60 minutes. After fully dissolving, cool the temperature of the reaction kettle to room temperature 25°C and add nano-silica sol and nano-indium oxide. After stirring for 30 minutes, weigh and pack with a 300-mesh filter.

Abstract

The invention provides novel scaling powder. The scaling powder comprises following raw materials including, by weight percent, 0.5%-5% of an active agent, 0.1%-5% of a film forming agent, 85%-99% ofa solvent and 0.1%-5% of a conductive addition agent. According to a scaling powder preparing method, the components are weighed according to the weight percent, the solvent is added in a reaction kettle, the heating temperature is 40-60 DEG C, the active agent is added, stirring is conducted till the active agent is dissolved, then the film forming agent is added, stirring is conducted for 60 min, and after sufficient dissolving, the temperature of the reaction kettle is reduced to the normal temperature, the conductive addition agent is added, and filtering and filling are conducted after stirring is conducted for 30 min.

Description

technical field [0001] The invention belongs to the technical field of soldering flux, and in particular relates to a novel soldering flux and a preparation method thereof. Background technique [0002] The traditional flux for solar modules is only to remove the oxide layer on the ribbon, so that the ribbon and the battery can be firmly welded, and has no other functions. During the stringing process of resin-based photovoltaic fluxes, a large amount of smoke will be produced during the high-temperature soldering process at 220 ° C, which not only pollutes the environment, but also has a large resistance after the high-temperature volatilization of residual substances, which will affect the serial connection of cells. Conductivity, thereby affecting the power generation of the entire component. [0003] The film-forming substance in the prior art is mainly a resin system, because the resin has a certain degree of insulation and poor conductivity. In the technology of the p...
