Abstract

The invention discloses a bicomponent silicone structural adhesive for solar thermal power generation. The bicomponent silicone structural adhesive comprises a component A and a component B. The component A includes: 10-40 parts of type 1 alpha, omega-dihydroxy polydimethylsiloxane; 60-100 parts of type 2 alpha, omega-dihydroxy polydimethylsiloxane; 5-35 parts of a plasticizer; 80-150 parts of type 1 filler; and 0.5-10 parts of type 2 filler. The component B includes: 20-35 parts of carbon black; 25-40 parts of a plasticizer; 10-80 parts of a type 1 cross-linking agent; 25-80 parts of a type 2cross-linking agent; 2.5-20 parts of a coupling agent; and 0.1-2 parts of a catalyst. The invention also discloses a preparation method of the bicomponent silicone structural adhesive for solar thermal power generation. The silicone sealant can be used for structural bonding outdoors, and is especially suitable for structural bonding fixation between a solar thermal power generation reflecting mirror and support.

Description

technical field [0001] The invention relates to a silicone adhesive and a preparation method thereof, in particular to a two-component silicone structural adhesive for solar thermal power generation and a preparation method thereof, belonging to the technical field of organic silicon structural adhesives. Background technique [0002] According to the different ways of solar power generation, it can be divided into solar photovoltaic power generation and solar thermal power generation. Solar thermal power generation is a solar energy utilization technology that uses concentrated solar collectors to gather solar radiation energy, and then uses the energy to heat a certain working fluid to hundreds of degrees Celsius, and use this working fluid to drive a generator to generate electricity. Since the birth of solar thermal power generation technology in the 1950s, the current global solar thermal power generation market is mainly concentrated in Spain, the United States and oth...
