Problems solved by technology

However, due to open-air use, the surface of the FRP radome tends to accumulate rainwater, atmospheric dust, bird droppings, etc., which will affect the performance of radar sensitivity, accuracy, and detection distance.
At the same time, acid rain, atmospheric dust, bird droppings, ultraviolet rays, etc. also have a certain erosion and damage effect on the FRP radome.
Since FRP radome is mostly sphe

Abstract

The invention relates to a surface antifouling corrosion-resistant protectant for glass fiber reinforced plastic and other polymer products. The surface antifouling corrosion resistant protectant for glass fiber reinforced plastic and other polymer products, which is provided by the invention, is composed of fluoro-alkyl silane, long-chain alkyl silane, nanometer SiO2, alkyl silicate, alcohol, inorganic acid catalysts and de-ionized water or distilled water. The surface antifouling corrosion resistant protectant for glass fiber reinforced plastic and other polymer products, which is provided by the invention, can form a layer of low surface water-repellent, oil-proof, antifouling, anti-sticking, anti-ultraviolet and corrosion-resistant coat film on the surfaces of the glass fiber reinforced plastic and the other polymer products, the water contact angle can reach as high as 149 DEG, the purposes of effective reduction of rain accumulation as well as the attachment of atmospheric dust, guano, etc. on the surfaces of the glass fiber reinforced plastic and the other polymer products, acid rain corrosion damage resistance, salt mist corrosion damage resistance, ultraviolet corrosion damage resistance and reduction of use and maintenance cost are achieved.

Description

technical field [0001] The invention relates to a surface modification treatment agent for FRP and other polymer products, in particular to an antifouling and corrosion-resistant protective agent for the surface of FRP and other high molecular products. Background technique [0002] FRP radar radome is used to protect the radar antenna to work around the clock, and to prevent the influence of rain, salt spray, atmospheric dust, ultraviolet rays, strong wind, etc. on the performance of the radar antenna. However, due to open-air use, rainwater, atmospheric dust, bird droppings, etc. tend to accumulate on the surface of FRP radome, which will affect the performance of radar sensitivity, accuracy, and detection distance. At the same time, acid rain, atmospheric dust, bird droppings, ultraviolet rays, etc. also have a certain erosion and damage effect on the FRP radome. Since FRP radomes are mostly spherical and bulky, manual cleaning is very difficult, resulting in high mainte...
