Description

Technical Field

[0001] This invention relates to a water-based inorganic two-component anti-rust and fireproof coating, particularly an anti-rust and fireproof coating that is free of volatile organic compounds and toxic heavy metals, is non-toxic and odorless, harmless to the human body and the environment, and thus meets green environmental protection standards. Prior Technology

[0002] Note: Traditional organic solvent coatings have long suffered from the following problems: 1. Organic coatings are composed of resins, pigments, fillers, solvents and various additives. Most of the organic solvents that evaporate from the film are toxic substances, which are not only harmful to the human body, but also cause environmental pollution and seriously harm the health of on-site construction workers. 2. Traditional organic solvents produce an irritating odor and will evaporate into the air for a long time during the brushing and drying process, directly irritating and damaging the human sensory organs. 3. It has the disadvantage of being flammable, which may pose a risk to the construction process or the environment. 4. Commercially available paints, due to the addition of organic solvents and hardeners, can only be used up in one go. Leftover paint not only causes a certain amount of waste, but also requires special disposal, otherwise it will cause further environmental pollution.

[0003] The aforementioned shortcomings of traditional coatings, besides not being environmentally friendly, also include the issue of flammability, which involves whether the coating itself has fire-retardant properties.

[0004] However, given the deteriorating global environment, moving towards net zero is an international trend and an urgent shared task. The research and promotion of various green energy materials is both imperative and their prospects cannot be ignored. Therefore, the applicant previously applied for an "inorganic water-based two-component anti-rust coating," which was approved by the Bureau under certificate number I737492. This previous application used a combination of magnesium compounds, silane, mica, talc, and suspending agents to form the anti-rust coating, which was applied directly to the substrate by spraying to achieve rust prevention. It contained no harmful substances or heavy metals, was non-toxic, odorless, posed no harm to human health, and did not pollute the environment, thus meeting environmental protection requirements. However, with the development of flame-retardant technology and the increasing demands on fire-retardant material performance, the applicant, through continuous research and breakthroughs, conceived a further improvement, enabling the original anti-rust coating to possess effective fire-retardant properties, hoping to meet the functional requirements of various levels of rust prevention and fire resistance in the industry. Summary of the Invention

[0005] The main objective of this invention is to provide a water-based inorganic two-component anti-rust and fireproof coating that achieves both anti-rust and fireproofing properties. After hardening, it exhibits minimal shrinkage, good adhesion, and is not prone to cracking. It is also resistant to high temperatures and ultraviolet radiation, contains no added polymers, volatile organic compounds, or toxic heavy metals, and is non-toxic, odorless, and harmless to humans and the environment, thus meeting green and environmentally friendly standards.

[0006] The aforementioned water-based inorganic two-component rust-preventive and fire-retardant coating comprises at least a first component (Agent A) based on magnesium compounds, silane, mica, talc, suspending agents, and silica, and diluted with clean water; and a second component (Agent B) based on phosphorus compounds, potassium compounds, titanium dioxide, talc, suspending agents, and silica, and diluted with clean water. The first component (Agent A) and the second component (Agent B) exist separately in liquid form and are stirred separately during manufacturing. The additional materials are added sequentially and stirred thoroughly to form a liquid gel. In application, the first component (Agent A) and the second component (Agent B) are applied directly to the target object in equal proportions via spraying to achieve rust and fire prevention.

[0007] The aforementioned water-based inorganic two-component rust-preventive and fire-retardant coating contains, in its first component (Agent A), magnesium compounds at 18% to 28%, silanes at 1% to 3.5%, mica at 7% to 12%, talc at 3% to 8%, a suspending agent at 1% to 2.5%, silicon dioxide at 5% to 10%, and clean water at 59% to 65%.

[0008] The aforementioned water-based inorganic two-component rust-preventive and fire-retardant coating contains, in its second component (Agent B), phosphorus compounds at 12% to 19%, potassium compounds at 11% to 17%, titanium dioxide at 6% to 10%, talc at 5% to 9%, a suspending agent at 1% to 2.5%, silicon dioxide at 7% to 10%, and clean water at 51% to 59%.

[0009] The aforementioned water-based inorganic two-component rust-preventive and fire-retardant coating, wherein the production process of the first component (Agent A) and the second component (Agent B) is as follows: first, a suspending agent is prepared, then the first component is added, and after mechanical stirring and wet grinding, the components are dispersed. After the second component is added, the components are dispersed, filtered, and emulsified to complete the finished product of the inorganic water-based inorganic two-component rust-preventive and fire-retardant coating.

[0016] The water-based inorganic two-component rust-preventive and fire-retardant coating of this invention has at least the following advantages compared with traditional rust-preventive coatings: 1. Since this invention does not contain any organic compounds (VOCs), it will not cause pollution to the environment and will not harm the health of on-site construction personnel. 2. This invention uses water as a diluent, making it a non-toxic and odorless environmentally friendly product. Because it does not contain toxic heavy metals found in traditional organic solvents, it has no irritating odor, is harmless to the human body, and will not produce any secondary pollution residues. 3. This invention has the dual functions of rust resistance and fire prevention, and also features excellent wear resistance, aging resistance, weather resistance, and fast drying time, making it more valuable for industrial applications than traditional coatings. 4. This invention has the characteristics of being safe and non-flammable, which can significantly reduce hidden dangers in the construction process and construction environment. 5. This invention does not produce any irritating odor during the spraying process, and therefore will not irritate the workers or cause harm to their organs. 6. Since this invention does not add organic solvents or curing agents, the remaining paint after construction can be stored in a cool place, thus avoiding waste of materials or secondary environmental pollution. 7. This invention utilizes the characteristics of inorganic materials, and a certain film thickness can be achieved through two-component mechanical spraying, which can reduce the number of spraying operations and lower construction costs. 8. After the first spraying, the drying time of this invention is fast, and subsequent spraying can be carried out immediately without waiting for the drying time of the underlying coating. This makes construction operations such as thick layer stacking spraying or repair more convenient, thereby shortening the site recycling time and facilitating the arrangement of subsequent work processes. 9. Since the coating of this invention is not a typical heat-expanding fire retardant paint, it can be used in indoor or outdoor environments. Even without the protection of a topcoat, there is no risk of peeling, and it also meets the dust-free construction standards of high-tech factories.

[0017] The foregoing embodiments are merely illustrative of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any minor modifications or alterations will not depart from the essence of the present invention and will not deviate from its spirit and scope.
