Abstract
Provided are a high-temperature-resistant anti-corrosive coating and a preparation method. The high-temperature-resistant anti-corrosive coating comprises, by weight parts, 812 parts of potassium silicate solution, 32 parts of lithium hydroxide solution, 337 parts of CH3Si (OCH3), 68 parts of water, 139 parts of wollastonite, 37 parts of boron nitride, 41 parts of fine grain aluminum oxide, 35 parts of superfine zinc oxide and 38 parts of titanium oxide. The high-temperature-resistant anti-corrosive coating can be used for base layer painting of automobiles, aerospace, toys and outdoor sports equipment. The high-temperature-resistant anti-corrosive coating has the advantages of being convenient to transport and construct and non-toxic, having no foreign smell and being free of pollution and has the advantages of being high in coating hardness and resistant to friction, impact, high temperature, corrosion, aging, weather, radiation, salt fog and water.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of protective system, can be used for the fire-resistant anticorrosion paint of basic unit's brushings such as automobile, space flight, toy, outdoor activity equipment, there is transport, easy construction, nontoxic, free from extraneous odour, the advantage such as pollution-free, and there is the features such as coating hardness is high, friction resistant, shock resistance, fire resistant anticorrosive, resistance to deterioration is good, weather-proof, radioprotective, salt spray resistance, water resisting property are good.
Background technology
Protective system, is generally divided into conventional protective system and heavy-duty coating, is requisite a kind of coating in paint.Conventional protective system is under general condition, plays etch-proof effect to metal etc., the life-span that protection non-ferrous metal uses; Heavy-duty coating refers to relatively conventional protective system, can apply in relatively harsh corrosive environment, and has a class protective system that can reach the protection period longer than conventional protective system.The antiseptic principle of general protective system is chemistry, physics and electrochemistry direction; below detailed explanation: one, the rot-resistant principles of chemistry: the rot-resistant principles of chemistry are exactly neutralize harmful acid-base material for neutral innoxious substance, protect the material in corrosion protection coating not to be subject to the infringement of corrosives.Often add some amphoteric substances, such as aluminium hydroxide, hydrated barta and zinc oxide etc. in rust proof paint, these materials are easy to and soda acid nuisance generation chemical action, and realize preservative effect.Two, rot-resistant physical principle: rot-resistant physical principle is exactly protected material and extraneous corrosives are kept apart with corrosion protection coating.The physical principle of rust proof paint is exactly use membrane-forming agent to obtain fine and close corrosion protection coating, isolates the injury of preservative activity to protected material, such as, just can form lead soap after leaded coating and oil plant reaction, ensure the compactness of corrosion protection coating.Three, rot-resistant electrochemical action: rot-resistant electrochemical action refers to adds some special materials in rust proof paint, anticorrosion ion is formed by reacting during rust proof paint like this at moisture and oxygen, make the metallic surface passivation such as iron and steel, thus stop the stripping of metal ion, arrive rot-resistant object, modal in this particular matter is exactly chromic salt.Fire-resistant anticorrosion paint is the aqueous inorganic paint adopting special high-temperature solution and inorganic polymer to process, the Heat and corrosion resistant coating of coating spontaneous curing, coating filmogen: make interpenetrating net polymer based on inorganic polymer as filmogen.Fire-resistant anticorrosion paint can protect the effects such as matrix is anticorrosion, anti-oxidant, closed, wear-resistant protection in hot environment, and coating stability is high, can react in high temperature environments with other bioactive molecules, long service life.Fire-resistant anticorrosion paint brushing is on high-temperature furnace body metal; can resistance to anticorrosion, the resistibility that improves acid-fast alkali-proof of available protecting high-temperature furnace body metal in thermal-flame environment; protection metal is not by effects such as anti-oxidant, closed protectives; overcome common protective system extremely inadaptable under the high temperature conditions; heatproof is inadequate, easily produces the defects such as peeling, crowfoot cracks, variable color.
Summary of the invention
The object of the present invention is to provide a kind of protective system, can be used for the fire-resistant anticorrosion paint of basic unit's brushings such as automobile, space flight, toy, outdoor activity equipment, there is transport, easy construction, nontoxic, free from extraneous odour, the advantage such as pollution-free, and there is the features such as coating hardness is high, friction resistant, shock resistance, fire resistant anticorrosive, resistance to deterioration is good, weather-proof, radioprotective, salt spray resistance, water resisting property are good.
Present invention employs such technical scheme: the material in described fire-resistant anticorrosion paint and weight proportion respectively: potassium silicate solution 812 parts, lithium hydroxide aqueous solution 32 parts, CH
