Embodiment 1

[0037] Get 60kg of acrylic modified silicone resin, 15kg of hazelite titanium dioxide, 9.7kg of gypsum powder, 10kg of glass phosphorus flakes, 0.3kg of A-560 and 5kg of modified nano silicon dioxide:

[0038] Among them, the modified nano-silica is a coupling agent acetone solution prepared by drying nano-silica at 80-100°C, and then mixing it with 0.06kg KH-550 and 1.2kg acetone. It is made by treating for 30 minutes, resting for about 60 minutes, and then heating to about 60°C to remove acetone.

[0039] Add the modified nano-silica to the acrylic-modified silicone resin, stir at a high speed of about 1200 rpm for 40 minutes, stand still for 30 minutes, then add A-560 and stir for 10 minutes, and then stir Add hilarite titanium dioxide, gypsum powder and glass phosphorus flakes and continue to stir for 30 minutes. After grinding, the fineness reaches about 40 μm to obtain a protective coating for high-temperature pipelines on the ground.

Abstract

The present invention discloses one kind of nanometer antiweathering and waterproof ceramic paint with high mechanical strength and its preparation process and application. The paint consists of filming material, stuffing, assistant and modifying nanometer powder preferably in the weight ratio of 20-60 to 30-65 to 1-5 to 1-10. The paint of the present invention has excellent waterproof performance, high weather resistance, high mechanical strength and easy use, and may be used as the protecting layer of high temperature pipeline.

Description

technical field [0001] The invention relates to the field of materials, in particular to nano-ceramic coatings with high waterproof and weather-resistant mechanical strength. Background technique [0002] With the rapid development of industry, people's living standards have been greatly improved. Many industries need high-temperature steam heat (generally below 600 ° C), and central heating and heating in living quarters. These high-temperature gases come from heating companies that produce high-temperature gases in the suburbs of cities, or industrial exhaust gases (such as exhaust gases from power plants, etc.). High-temperature gas is often transported to the city through pipelines, and the transport distance ranges from a few kilometers to tens of kilometers. Most of the pipelines go underground, and a few go above ground. Whether it is going on the ground or underground, the pipeline needs to be anti-corrosion (four seasons for gases with a high temperature above 200...
