Embodiment 1

[0018] Embodiment 1: in parts by mass, using 60 parts of epoxy resin polymers, 16 parts of ammonium polyphosphate, 6 parts of pentaerythritol, 1 part of zinc borate, 2 parts of aluminum hydroxide, 0.3 parts of leveling agent, 15 parts of acetone as It is prepared from raw materials, wherein the epoxy resin polymer is formed by high-temperature esterification reaction of epoxy resin, linseed oil, catalyst zinc oxide and xylene. Fully pulverize zinc borate and aluminum hydroxide and add it to the mixture made of epoxy resin polymer, ammonium polyphosphate, pentaerythritol and acetone, then add zinc borate, aluminum hydroxide and leveling agent for high-speed homogeneous dispersion, Finally get the paint.

Embodiment 2

[0019] Embodiment 2: in parts by mass, adopt 80 parts of epoxy resin polymers, 20 parts of ammonium polyphosphate, 8 parts of pentaerythritol, 3 parts of zinc borate, 4 parts of aluminum hydroxide, 0.6 part of leveling agent, 20 parts of acetone as It is prepared from raw materials, wherein the epoxy resin polymer is formed by high-temperature esterification reaction of epoxy resin, linseed oil, catalyst zinc oxide and xylene. Fully pulverize zinc borate and aluminum hydroxide and add it to the mixture made of epoxy resin polymer, ammonium polyphosphate, pentaerythritol and acetone, then add zinc borate, aluminum hydroxide and leveling agent for high-speed homogeneous dispersion, Finally get the paint.

Embodiment 3

[0020] Embodiment 3: in parts by mass, adopt 85 parts of epoxy resin polymers, 23 parts of ammonium polyphosphate, 9 parts of pentaerythritol, 3 parts of zinc borate, 5 parts of aluminum hydroxide, 0.7 part of leveling agent, 23 parts of acetone as It is prepared from raw materials, wherein the epoxy resin polymer is formed by high-temperature esterification reaction of epoxy resin, linseed oil, catalyst zinc oxide and xylene.

Abstract

Steel structure protective paint is characterized by comprising the following raw materials by mass: 60-90 parts of epoxy ester polymer, 16-25 parts of ammonium polyphosphate, 6-10 parts of pentaerythrite, 1-4 parts of zinc borate, 2-6 parts of aluminium hydroxide, 0.3-0.8 part of a flatting agent, and 15-25 parts of acetone. According to the paint, zinc borate and aluminium hydroxide are fully smashed to be added into a mixed solution formed by the epoxy ester polymer, ammonium polyphosphate, pentaerythrite and acetone; then zinc borate, aluminium hydroxide and a flatting agent are added to carry out high-speed homogeneous dispersion. The air drying performance of the brushed paint is optimized, and the formula is scientific. When the paint is applied to steel structures for anti-corrosion brush, the coating is dense, the flatness is high, and also, the coating rigidity is improved. Moreover, the paint has a certain uvio-resistant function, has low possibility of breakage and partial rust to prolong the service life of the coating, and is wide in application range.

Description

technical field [0001] The invention relates to a coating, in particular to a protective coating for steel structures, and belongs to the technical field of protective coatings. Background technique [0002] At present, steel structures are more and more widely used in construction, machinery and other fields. Steel structures have the advantages of easy forming, mass production, and convenient installation. Steel structures can partially replace brick and concrete structures in the construction field. Large-scale factories also use steel structures. structure. Steel structures will rust in natural environments such as humidity, and need to be painted with anti-corrosion and anti-rust paints. However, the existing steel structure paints have simple formulas, short service life, poor UV resistance, and are prone to damage and local corrosion after a long time , affecting the service life of the steel structure itself. [0003] For example, the Chinese patent authorization p...
