Problems solved by technology

Although the enamel steel plate used for interior decoration has high hardness, fire resistance and weather resistance, because its coating has no toughness, it has the fatal weakness of not being impact resistant. Highly affected and irreparable
When enamel steel plate is glazed, it is cured at a temperature above 800 degrees, and the energy consumption is relatively high.
At the same time, the coatings in the prior art are prone to gelation at an excessive speed, and there is no advection time, so that the cured coating loses its luster as a whole and affects the appearance of the painted part

Embodiment 1

[0029] A tough inorganic ceramic coating comprising the following components:

[0030]

[0031] The preparation method of ceramic coating as above, comprises the following steps:

[0032] 1. Paint preparation: Add the weighed and measured components in the ceramic pot in sequence, stir at high speed for 3 hours, pour it out and mature for 3 hours, and filter it with a filter of 120 mesh or above for later use.

[0033] 2. Surface treatment of the workpiece: degrease the surface of the workpiece and then perform sandblasting treatment, and clean the workpiece. The workpiece must be sprayed within 24 hours after sandblasting.

[0034] 3. Construction: Adjust the pressure of the spray gun between 0.4-0.8Mpa; control the thickness of the paint film between 25um-35um, and control the viscosity of the paint during spraying between -4 cups and 11-20 seconds. Ethanol or acetone can be used for viscosity adjustment.

[0035] 4. Curing: curing under the condition of 0-185 degrees, t...

Abstract

The invention provides a tough inorganic baked-porcelain paint. The paint is characterized in comprising the components of: a base material, distilled water, a pigment, an organic solvent, an organic acid adjusting agent, a silica curing agent, and a coupling agent. The pH value of the pigment is regulated to 8-10H by using sodium hydroxide, and preferably 8-9H. The base material is a nano-grade oxide. The organic solvent includes alcohols, ethers, and ketones. The silica curing agent includes ethylsilane substituted derivatives. After the paint is cured, a formed coating has high hardness, and the coating is not subjected to any oxidation reaction under high temperature. With an ultraviolet resistance, the coating has ultrahigh weatherability in the respects of color and gloss maintenances. The coating also has certain toughness, such that a coating cracking phenomenon is prevented when the coating is impacted by a hard object. The paint can cure under 0-185 DEG C, such that low-temperature curing can be carried out, such that energy consumption is low. Also, if a surface reparation problem occurs, curing reparation can be carried out with the assistance of a high-temperature incandescent lamp.

Description

technical field [0001] The invention relates to a baking varnish coating, in particular to a tough inorganic baking enamel coating. Background technique [0002] At present, fluorocarbon, plastic spraying, and automobile baking varnish coatings are widely used in curtain wall decoration, outdoor signage, building interior decoration and other fields, and the coating hardness of the decorative materials sprayed by these coatings can only reach 2H at the highest, and the surface is easily scratched Injuries have a great impact on the aesthetics of buildings. In terms of fire performance, it is already a very high standard for many coatings to reach the B1 fire performance, which is far from meeting the increasingly high fire protection requirements of buildings. Outdoors, the weather resistance of organic coatings based on fluorocarbon coatings is about 8 years, and sometimes lower. For some buildings that require semi-permanent, after a certain period of time, the fading of ...
