Abstract
The invention relates to the technical field of solar backboards, in particular to a solar backboard with a high barrier property. The solar backboard with the high barrier property comprises a PET base material layer, bonding layers arranged on two sides of the PET base material layer and a barrier layer arranged on the other side of the bonding layers, wherein the barrier layer is prepared from the following raw materials in parts by weight: 40-60 parts of long carbon chain nylon, 18-22 parts of nanoscale inorganic powder and 2-4 parts of a heat stabilizer, and the weight ratio of the long carbon chain nylon to the nanoscale inorganic powder is (2-3): 1. According to the invention, by selecting the materials of the barrier layer and the ratio of the raw materials, the solar backboard has excellent weather resistance and can effectively prevent the invasion of water vapor. The manufacturing process of the solar backboard is simple and easy to operate.
