Anticorrosion surface coating for flat-plate solar collector and preparation technology thereof

Abstract

The invention relates to an anticorrosion surface coating for a flat-plate solar collector. The anticorrosion surface coating is prepared from the following raw materials in parts by weight: 50-60 parts of modified organic silicon resin, 40-50 parts of epoxy resin, 30-40 parts of polyamide resin, 10-20 parts of phenolic aldehyde amine resin, 2-4 parts of polyethylene glycol, 6-8 parts of kieselguhr, 5-7 parts of glass powder, 15-25 parts of anti-flaming polyether polyol, 5-7 parts of nano calcium carbonate, 5-7 parts of tetramethylsilane, 3-5 parts of zinc oxide, 5-7 parts of graphite powder,15-17 parts of modified plant fiber powder and 100-120 parts of deionized water. The invention has the beneficial effects that the processing process is simple, scientific and normative, the formula is reasonable and the prepared anticorrosion coating is coated on the solar collector surface for preventing the solar collector surface from corrosion, is durable, is easy to fall off and discolor, isconvenient for long-term use and has an obvious use effect.

Description

technical field [0001] The invention relates to the technical field of solar energy processing, in particular to an anti-corrosion surface coating for a flat solar heat collector and a preparation process thereof. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure, and vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. Get the hot water you need. [0003] Nowadays, solar water heaters h...

Problems solved by technology

[0003] Nowadays, solar water heaters have different shapes and designs for different use environments. Flat plate and vacuum tube types are the most widely used products nowadays. At present, most urban buildings are high-rise residential buildings, so in actual solar energy research and development, wall-mounted Type solar energy is one of the most popular solar solutions. In actual use of wall-mounted solar energy, its heat collectors are installed outdoors. In the corresponding use, because it is exposed to the outside world, it will involve a lot of energy during long-term use. Therefore, the corresponding surface anti-corrosion treatment must be carried out, and due to the performance requirements of the heat collector itself, heat collection is required, so the heat collector itself is also a long-term high temperature, and the surface anti-corrosion treatment adopts conventional anti-corrosion coatings In use, due to the long-term high temperature, the effect of conventional as if the coating is not obvious when it is used, and the coating is easy to fall off under the effect of high temperature, so the effect of use is not obvious
