Embodiment 1

[0024] The first step, the preparation of modified terpene resin: put 120g of organic solvent into the reaction kettle and heat to reflux state; 5g of 1-trifluoromethyl-1,3-butadiene, 10g of hydroxypropyl acrylate, styrene 15g and 10g of initiator are mixed evenly and dropped into the organic solvent; after the dropwise addition, the temperature is lowered to 70°C, 80g of terpene resin is added, and the reaction is carried out. The reaction time is 2 hours, and then filtered and dried in vacuum to obtain the modified terpene vinyl resin; the organic solvent is ethylene glycol, and the initiator is azobisisobutyronitrile;

[0025] Step 2. Preparation of modified filler: Dissolve 20g of alkyd resin in 120g of tetrahydrofuran as the first mixed solution; then take 15g of calcium silicate and 14g of potassium sulfate whiskers and disperse them in 150g of tetrahydrofuran as the second mixed solution liquid; the first mixed solution was mixed with the second mixed solution, stirred ...

[0036] The first step, the preparation of modified terpene resin: put 130g of organic solvent into the reaction kettle and heat to reflux state; 7g of 1-trifluoromethyl-1,3-butadiene, 15g of hydroxypropyl acrylate, styrene 17g and initiator 12g were mixed evenly and dropped into the organic solvent; after the dropwise addition, the temperature was lowered to 75°C, and 85g of terpene resin was added to react. The reaction time was 3 hours, and then filtered and vacuum-dried to obtain modified terpene vinyl resin; the organic solvent is ethylene glycol, and the initiator is azobisisobutyronitrile;

[0037] Step 2. Preparation of modified filler: Dissolve 25g of alkyd resin in 130g of tetrahydrofuran as the first mixed solution; then take 18g of calcium silicate and 18g of potassium sulfate whiskers and disperse them in 170g of tetrahydrofuran as the second mixed solution liquid; the first mixed solution was mixed with the second mixed solution, stirred for 2 hours under the acti...

Abstract

The invention relates to a preparation method of a modified epoxy resin anticorrosive paint directly applied to rusty scales, belonging to the technical field of paints. The method mainly comprises the following steps: preparing a modified terpene resin, preparing a modified filer, and preparing an epoxy resin emulsion; mixing the modified terpene resin, the modified filer, the modified water-based epoxy resin emulsion, polyvinyl acetate, dipentaerythritol, zinc borate, molybdenum disulfide, magnesium borate, iron oxide red, zinc phosphate, barium sulfate, aluminum tripolyphosphate, titanium oxide, zinc oxide, a defoaming agent and water; and dispersing uniformly to obtain the paint. By modifying the filler, epoxy resin and terpene resin, the water-based epoxy resin anticorrosive paint provided by the invention has favorable adhesive force for rusty substrates, and also has favorable corrosion resistance.

Description

technical field [0001] The invention relates to a preparation method of a modified epoxy resin anticorrosion coating directly applied to a rust layer, and belongs to the technical field of coatings. Background technique [0002] Coating is a substance in a fluid state or a powder state, which can be coated on the surface of a coated object and can be dried and solidified to form a firmly adhered uniform and continuous film. Since past coatings were almost inseparable from vegetable oil, coatings have long been referred to as paints. Coatings are generally not used alone as engineering materials, but are always coated on the surface of an object to protect, decorate or endow the material with a certain special function. According to the different forms of coatings, they can be divided into water-based coatings, solvent-based coatings, powder coatings, etc. Compared with solvent-based coatings, the biggest advantage of water-based coatings is that the amount of organic so...
