Embodiment 1

[0035] Mica pretreatment: calcining muscovite at 700°C for 90 minutes to obtain mica clinker, immersing the mica clinker in ammonium bicarbonate solution with a mass concentration of 50% for 20 minutes, taking out the mica clinker, and calcining for a second time at 200°C for 40 minutes , and finally pass through a 10-mesh sieve.

[0036] The inorganic coating is a phosphate coating, and the formulation of the phosphate coating is referred to the embodiment 1-3 of the CN1618887A invention patent (disclosed on May 25, 2005). During the preparation of the phosphate coating or after the preparation, the pretreated muscovite is added , mixed evenly, the amount of muscovite added accounted for 3% of the mass percentage of the inorganic coating.

[0037]

Embodiment 2

[0039] Mica pretreatment: calcining phlogopite at 1000°C for 60 minutes to obtain mica clinker, immersing the mica clinker in ammonium bicarbonate solution with a mass concentration of 60% for 10 minutes, taking out the mica clinker, and calcining it for a second time at 300°C for 20 minutes , and finally pass through a 15-mesh sieve.

[0040] The inorganic coating is a phosphate coating (commercially available, Yangzhou Meitushi Jinling Special Coatings Co., Ltd., the product name is inorganic phosphate zinc-rich coating, model ET-98), and the pre-treated phlogopite is added to the phosphate coating, mixed Uniformity is sufficient, and the addition amount of phlogopite accounts for 15% of the mass percentage of the inorganic coating.

Embodiment 3

[0042] Mica pretreatment: calcining muscovite at 800°C for 80 minutes to obtain mica clinker, immersing the mica clinker in ammonium bicarbonate solution with a mass concentration of 55% for 15 minutes, taking out the mica clinker, and calcining for a second time at 250°C for 30 minutes , and finally pass through a 12-mesh sieve.

[0043] The inorganic coating is alkali metal silicate coating (commercially available, Xinhua Yan Refractory and Insulation Material Co., Ltd., product name silicate coating), during the preparation process of the alkali metal silicate coating or after the preparation is completed, add pre-treated white cloud Mother, just mix evenly, the amount of muscovite added accounted for 10% of the mass percentage of the inorganic coating.

Abstract

The invention discloses a mica inorganic paint and usage method thereof, and solves the problem of bad adhesive force of the prior inorganic paint on the metal surface. The invention is made from modified mica inorganic paint, and 3-15% of mica by mass is added into the inorganic paint. According to the invention, using the mica modified inorganic paint can substantially improve the adhesive force of the inorganic paint on the metal surface, and achieve the same improving effect of the inorganic paint adhesive force after sand-blast treatment or corrosion roughening treatment of the metal surface. The sand-blast treatment or corrosion roughening treatment is not needed on the metal surface, thereby substantially simplifying the construction difficulty. The weatherability, the high temperature resistance performance, the heat insulation performance and insulating property are also improved.

Description

technical field [0001] The invention relates to the technical field of inorganic paint production, in particular to a mica inorganic paint and a use method thereof. Background technique [0002] Inorganic coatings mainly refer to the coatings prepared by using silicate and phosphate compounds as binders, adding various pigments, fillers, additives, and curing agents. Among them, silicate polymer compounds can be divided into alkali metal Silicates and silica sols. This kind of coating with inorganic binder as the film-forming substance has low film-forming temperature, excellent weather resistance, very stable under the action of ultraviolet light, good heat resistance, non-combustible in case of fire, and good resistance to heat. Pollution, not easy to absorb dust, can maintain a bright decorative effect, no volatile organic compounds are produced during production and use, will not pollute the environment, rich raw material resources, low cost and other advantages, so it ...
