Embodiment 1

[0019] The water-based paint with high temperature resistance of the present invention comprises the following components:

[0020] Water, epoxy-modified silicone resin, bisphenol A epoxy resin, water-based acrylic resin, oxidized starch, organic phosphonic acid, zinc oxide, sodium borate, sepiolite, borax, silica sand, polydimethylsiloxane , Calcium Carbonate, Propylene Glycol Butyl Ether.

[0021] Epoxy-modified silicone resin, bisphenol A epoxy resin, and water-based acrylic resin are film-forming substances. Silicone polymers have Si-O bonds as the main chain and have good heat resistance; epoxy resins have good heat resistance after curing. Many outstanding excellent properties, such as strong adhesion to various materials, especially to metals, strong chemical corrosion resistance, high mechanical strength, good electrical insulation, corrosion resistance, etc. In addition, epoxy resin can be cured in a wide temperature range, and the volume shrinkage is small during cu...

Embodiment 2

[0024] Based on Example 1, the water-based paint with high temperature resistance further includes the following components: pearl powder, titanium dioxide, and kaolin. Pearlescent powder is non-toxic, high temperature resistant, light resistant, acid and alkali resistant, non-spontaneous, non-combustible, non-conductive, non-migrating, and can obtain suitable color light; titanium dioxide has good anti-flocculation and anti-fading effects; kaolin is white, fine, soft and soft Earthy, with good physical and chemical properties such as plasticity and fire resistance.

Embodiment 3

[0026]Based on the above examples, the described water-based coating with high temperature resistance comprises the following components in parts by weight: 60-80 parts of water, 80-90 parts of epoxy-modified silicone resin, 40-50 parts of bisphenol A Epoxy resin, 10-15 parts of water-based acrylic resin, 30-40 parts of oxidized starch, 10-15 parts of organic phosphonic acid, 5-10 parts of zinc oxide, 1-5 parts of sodium borate, 1-3 parts of sepiolite, 1-3 parts of borax, 10-15 parts of silica sand, 10-15 parts of polydimethylsiloxane, 5-8 parts of calcium carbonate, 5-10 parts of propylene glycol butyl ether. The present invention is based on the consumption of existing water-based paint, combined with experimental results and production costs, selected the amount of each component with excellent paint performance; It is a component with high temperature performance, but it does not affect the comprehensive performance of the coating, but can improve the strength, stability a...

Abstract

The invention discloses a water-based paint with high temperature resistance, which comprises the following components: water, epoxy-modified silicone resin, bisphenol A epoxy resin, water-based acrylic resin, oxidized starch, organic phosphonic acid, zinc oxide, boric acid Sodium, meerschaum, borax, silica sand, dimethicone, calcium carbonate, propylene glycol butyl ether. The present invention uses a large number of components with high temperature resistance. At high temperatures, the performance of each component will not change. The coating has good temperature resistance, and the biggest problem faced by the coating at high temperature is the curing of the coating. Fast, low viscosity, poor fluidity, the thickness of the formed film is large, the brittleness is high, and the service life of the coating is low; The coating cures rapidly at high temperature and forms an uneven film.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based coating with high temperature resistance. Background technique [0002] Ancient buildings have extremely high historical, scientific and artistic value. If they are destroyed, they cannot exist anymore; and ancient buildings are old and will inevitably be damaged by nature or man-made. Therefore, we need to repair and maintain ancient buildings . Coatings are often used in the process of repairing ancient building rooms, door walls, inner and outer eaves, palms, floors, and walls. Due to the complicated repair process and long construction period, it is best to complete the repair work at one time, which requires the paint to have good high temperature resistance, corrosion resistance, adhesion, water resistance and mechanical properties to avoid discoloration or damage to the paint. [0003] At present, water-based coatings can be widely used in electrical appliances, metallurgy, pet...
