Embodiment 1

[0013] Embodiment 1: The preparation method of water-based micaceous iron oxide, the prepared micaceous iron oxide is added to the water-based aminosilane compound and mixed evenly, the mixed material is heated to 200 degrees Celsius and then dehydrated, dried, proportioned and fed, After sieve analysis, water-based mica iron oxide was obtained. In this embodiment, the water-based mica iron oxide prepared is easy to disperse by utilizing the generality of the water-based aminosilane complex, which solves the defect of hard precipitation.

Embodiment 2

[0015] The preparation method of water-based micaceous iron oxide is to add the prepared micaceous iron oxide into the water-based aminosilane compound and mix evenly, heat the mixed material to 200 degrees Celsius, and then produce Aqueous micaceous iron oxide is obtained, and the aminosilane complex is 3-aminopropyltriethoxysilane. This embodiment uses a specific water-based aminosilane compound to further improve the dispersibility of the prepared water-based micaceous iron oxide, and completely solve the defect of hard precipitation.

Embodiment 3

[0017] The preparation method of water-based micaceous iron oxide is to add the prepared micaceous iron oxide into the water-based aminosilane compound and mix evenly, heat the mixed material to 170 degrees Celsius, and then produce Obtain water-based micaceous iron oxide, and described aminosilane compound is by the 3-aminopropyltriethoxysilane of 82% by weight, the 3-aminopropyltrimethoxysilane of 17% by weight and the N of 1% by weight -(β-Aminoethyl)-γ-Aminopropyl Trimethoxysilane mixed, dehydration time is 2 hours, drying is 1 hour, sieve analysis step with 330 mesh sieve to oxidize mica The iron is separated by sieve analysis, and the particle size of the water-based micaceous iron oxide after the sieve analysis and separation is 0.7 μm. In this way, the adhesion of the prepared water-based micaceous iron oxide is increased, and the coating prepared from the water-based micaceous iron oxide is very easy to polymerize with other substances, while retaining the easy disper...

Abstract

The invention discloses a preparation method for water-based mica iron oxide. The preparation method is as follows: adding the prepared mica iron oxide into a water-based amino silane compound and then uniformly mixing; and dehydrating, drying, proportioning and dosing, and carrying out sieve analysis after heating the mixed substances to obtain the water-based mica iron oxide. The invention further discloses water-based anticorrosive paint which comprises water-based mica iron oxide, acrylic emulsion, a flash-rust preventing agent, talcum powder, modified zinc phosphate, aluminum triphosphate, precipitated barium sulfate, zinc oxide, texanol ester alcohol, triethanolamine, a preservative and deionized water. According to the preparation method disclosed by the invention, mica iron oxide is obtained according to the conventional method for producing mica iron oxide, and the water-based mica iron oxide is obtained by further processing, so that the defect of the existing mica iron oxide hard precipitate is solved, and therefore, the water-based mica iron oxide is good in dispersion, and production cost of paint is lowered. When the prepared water-based mica iron oxide is used for preparing paint, anticorrosive effect of the prepared paint is improved.

Description

technical field [0001] The invention relates to a preparation method of water-based mica iron oxide, and also relates to a coating made of water-based mica iron oxide. Background technique [0002] Mica iron oxide is a classic and excellent anti-corrosion pigment. It has been widely used in the anti-corrosion coating industry for more than 30 years. Some disadvantages of mica iron oxide have been gradually discovered in many years of practice. Due to the large specificity of mica iron oxide (4.9-5.1 g / cm3), it has poor dispersion and poor storage stability. In this way, additives such as anti-settling agents and thixotropic agents must be used in coatings, and modified materials must be used to solve these problems. In addition, when making coatings, micaceous iron oxide The dosage of micaceous iron oxide should be properly controlled, so that the anti-corrosion coating cannot fully exert the anti-corrosion effect of micaceous iron oxide. Contents of the invention [0003...
