Problems solved by technology

There are mainly one-component silicone sealants (RTV-1 for short) on the market, but their outstanding disadvantage is that the surface dry time is long
So on this basis, a two-component silicone sealant (RTV-2 for short) was born. Although it can solve the problem of surface drying time, another defect it brings is inconvenient construction and poor yellowing resistance. Therefore, RTV-2 2 The application on solar modules is limited

Embodiment Construction

[0007] Embodiments of the present invention are as follows:

[0008] Material formula: 60 parts of hydroxyl-terminated polydimethylsiloxane, 60 parts of calcium carbonate reinforcing agent, 0.5% dibutyltin diacetate catalyst, 60 parts of methyl silane coupling agent, 2 parts of vinyl silane coupling agent.

[0009] Preparation process: Weigh 60kg of 40000mPa·S hydroxyl-terminated polydimethylsiloxane, 60kg of 1200 mesh calcium carbonate reinforcing agent, put them into a biaxial planetary stirring tank and stir for 30 minutes for vacuum dehydration, after cooling, add organic Tin catalyst, methyl silane coupling agent, vinyl silane coupling agent. Continue to stir under vacuum for 30 minutes to discharge the air bubbles in the mixed glue, and then press it into a plastic tube with a hydraulic filling machine.

[0010] The RTV-1 glue produced by the above-mentioned process is used as a sealing material for solar energy building. After testing, the weather resistance performanc...

Abstract

The invention relates to a macromolecular bonding seal material, in particular to a single-component silicone seal gum for a solar component used in a solar optoelectronic conversion device and a method for manufacturing the same. The single-component silicone seal gum for the solar component comprises the following raw materials in portion by weight: 50 to 60 portions of hydroxyl terminated polydimethyl siloxane, 55 to 60 portions of calcium carbonate reinforcing agent, 0.5 to 1 portion of dibutyltin diacetate catalyst, 55 to 60 portions of methyl silane coupling agent, and 1 to 2 portions ofvinyl silane coupling agent. Tests show that when the single-component silicone seal gum, produced by adopting the components and the method, is used for producing seal materials of the solar components, the seal materials have good weather resistance, a the surface drying time kept within 6 to 8 minutes in general, meet needs for quick scale production of the large-scale solar components, and meet the use requirements of the solar components on other items such as electrical property and the like.

Description

technical field [0001] The invention relates to a polymer adhesive sealing material, and relates to a single-component silicone sealant for solar modules used in solar photoelectric conversion devices and a manufacturing method thereof. Background technique [0002] The sealants currently used in solar modules are room temperature vulcanized silicone rubber. There are mainly one-component silicone sealants (RTV-1 for short) on the market, but their outstanding disadvantage is the long surface drying time. So on this basis, a two-component silicone sealant (RTV-2 for short) was born. Although it can solve the problem of surface drying time, another defect it brings is inconvenient construction and poor yellowing resistance. Therefore, RTV-2 2 The application on solar modules is limited. At present, there is an urgent need in the industry for a sealant product that can not only improve the surface dry time but also resist yellowing to replace the existing sealant. Contents...
