Problems solved by technology

[0003] Nowadays, solar water heaters have different shapes and designs for different use environments. Flat plate type and vacuum tube type are the most widely used products, but no matter how the shape is changed, all solar water heaters will involve the use of water storage tanks to achieve heat Water accumulates, but because the water storage tank is a hot water collection device, the internal water alternates between cold and hot for a long time, so the inner wall ages too quickly, and the actual heat volatilizes relatively quickly. Therefore, in actual use, the actual water storage tank The damage rate is also more frequent, resulting in high maintenance costs in the later period

Embodiment 1

[0024] A heat-insulating anti-aging coating for the interior of a solar water heater water storage tank, which is prepared from the following raw materials:

[0025] Butyl methacrylate 10kg, titanium dioxide 8kg, sodium hexametaphosphate 6kg, hydroxyethyl cellulose 6kg, talcum powder 5kg, alkyd resin 8kg, polyamide resin 50kg, sodium lauryl sulfate 8kg, shortening filler 20kg, Tributyl phosphate 6kg, styrene-acrylate copolymerized microemulsion 100kg;

[0026] The crisping filler is formed by mixing 6kg of diatomite, 5kg of montmorillonite powder, 6kg of starch and 2kg of quicklime, and then crisping, and the crisping method is as follows:

[0027] ①. After grinding diatomite, montmorillonite powder, starch and quicklime raw materials, mix them to obtain mixed fine materials;

[0028] 2. After mixing the above-mentioned dilute sulfuric acid of 3% of the total amount of mixed fine material raw materials, stir and compound evenly;

[0029] ③. Feed the raw materials in the abov...

Embodiment 2

[0037] Such as figure 1 Said, as another embodiment of the present invention, a heat-insulating solar water storage tank, the main body is a cylinder 1, the bottom of the cylinder 1 is provided with a water inlet pipe 2 and a water outlet pipe 3, and the water inlet pipe 2 A valve 4 is installed on the water outlet pipe 3, a rough inner lining plate 5 is arranged on the inner wall of the cylinder body 1, and a heat-insulating anti-aging paint is painted on the inner lining plate 5, and the cylinder body 1 The outer wall is wrapped with a layer of asbestos cover 6; the function of asbestos cover 6 is used to realize the normal heat preservation effect in the cylinder, and at the same time, a rough inner lining plate 5 is arranged inside to realize the fastening performance after the paint is painted;

[0038] The heat-insulating anti-aging coating is prepared from the following raw materials:

[0039] Butyl methacrylate 11kg, titanium dioxide 9kg, sodium hexametaphosphate 7kg,...

Abstract

The invention provides a heat-insulating and anti-aging coating for the interior of a water storage barrel of a solar water heater. The heat-insulating and anti-aging coating is prepared from the following raw materials: 10 to 12 parts of butyl methacrylate, 8 to 10 parts of titanium dioxide, 6 to 8 parts of sodium hexametaphosphate, 6 to 8 parts of hydroxyethyl cellulose, 5 to 7 parts of talcum powder, 8 to 10 parts of alkyd resin, 50 to 70 parts of polyamide resin, 8 to 10 parts of sodium dodecyl sulfate, 20 to 30 parts of a brittle filling material, 6 to 8 parts of tributyl phosphate and 100 to 120 parts of a styrene-acrylate copolymerized microemulsion. The invention has the following beneficial effects: the processing technology is simple, scientific and standard; the using effect issignificant; the heat-insulating and anti-aging coating prepared by using the processing technology provided by the invention is used for coating of the inner wall of the water storage barrel, so thetemperature transference generated by inside and outside differences in temperature is guaranteed, and corresponding heat-insulating and heat-preserving effects are realized; meanwhile, the heat-insulating and anti-aging coating has the advantages of excellent anti-aging performance, convenience in construction, facilitation to long-term use, and significant using effect.

Description

technical field [0001] The invention relates to the technical field of solar energy processing, in particular to a heat-insulating anti-aging coating inside a solar water heater storage tank and a processing technology 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 w...
