Description

A kind of resistance to moment is warming up to very high temperature coating and application thereof
Technical field
The present invention relates to a kind of coating material field, a kind of resistance to moment is warming up to very high temperature coating and application thereof.
Background technology
Resistance to moment is warming up to very high temperature coating and generally refers to temperature at short notice and rise suddenly near 300～1000 DEG C; and stop the of short duration time in high-temperature region; coating still has and does not ftracture, do not falls off; reach to protect coated product can keep the functions such as its basic physics, mechanical property; or when being occurred abnormal by protection assembly, the special functional coating that effectively protection is not damaged by by protection components and parts perimeter component；
Along with the industries such as space flight, automobile, household electrical appliance develop rapidly, under harsh applied at elevated temperature environment, the defencive function for product surface dope layer requires more and more higher；And high-temperature resistant coating on market, mainly the most commonly used with organosilicon heat-resistant coating, its heat resisting temperature scope is 200-700 DEG C, and has good resistance to water, electrical insulating property and good mechanical performance.But for needing resistance to 1000 DEG C or above high temp. protective coating still with nothing.
Summary of the invention
The technical problem to be solved in the present invention is: proposing a kind of resistance to moment is warming up to very high temperature coating and application thereof, resistance to moment be warming up to high using warming therapy temperature up to 1000 DEG C near, and rest on the very high temperature time up to more than 15 minutes, and still there is splitting resistance, compactness, conduction of heat and anti-flammability.
The technical solution adopted in the present invention is: a kind of resistance to moment is warming up to very high temperature coating, including organic resin, inorganic salt filler, sclerosing agent and solvent through graft modification；The percentage by weight of the described organic resin through graft modification, inorganic salt filler, sclerosing agent and solvent is respectively as follows: the organic resin 15%～45% through graft modification, inorganic salt filler 15%～50%, sclerosing agent 0.1%～3%, solvent 3%～20%；
The described organic resin through graft modification is the silane by organic resin and amino-contained or carries out graft reaction with dimethyldiethoxysilane and form；And this organic resin contains at least one in aluminum, silicon, zirconium, magnesium, calcium, titanium, iron ion.
Further, the silane of amino-contained of the present invention is diethylin MTES.
Further saying, organic resin of the present invention is epoxy silicone resin, poly-ammonia organic siliconresin, organosilicon phenolic resin and/or boron bakelite resin.
Further saying, inorganic salt filler of the present invention is one or more the mixture in metal-oxide, Pulvis Talci, mica powder, carbon black, graphite, molybdenum bisuphide, zinc phosphate.
Coating of the present invention may be used for encapsulating or the embedding of the electronic building bricks such as varistor, critesistor, sensor, Thermal Cutoffs.
The present invention is with resistant to elevated temperatures organic resin as base material, and the insulating heat-conduction material adding the graft modification containing aluminum, silicon, zirconium, magnesium, calcium, titanium, ferrum plasma forms organic material, utilizes associativity and the formability of organic material, forms in component external.Pyroprocess is born when assembly moment; organic material can be lost by slow self sacrifice; and organic graft; because sacrificing consume process containing aluminum, silicon, zirconium, magnesium, calcium, titanium, ferrum plasma; meeting high-temperature oxydation forms the metal-oxide of nano-scale; these nano-scale metal-oxides have the function of insulation heat biography and form the defencive function of resistance to instantaneous high-temperature, and another characteristic of this conjugate is high temperature heat-resistant impact.
The invention has the beneficial effects as follows: by adding a kind of or containing two or more graft modifications insulating heat-conduction material (containing aluminum, silicon, zirconium, magnesium, calcium, titanium, ferrum, boron ion), to improve the heat resistance of coating；The hardness of gained coating and heat shock resistance intensity are high, and adhesive force is strong, corrosion-resistant, have the impact resistance of excellence；There is good high-temperature resistant property, gained coating by room temperature moment enter 1000 DEG C, and hold temperature the time do not ftractureed in more than 15 minutes.
Detailed description of the invention
Presently in connection with embodiment, the present invention is further detailed explanation.
A kind of resistance to moment is warming up to high using warming therapy coating, resistance to moment be warming up to high using warming therapy temperature up to 1000 DEG C near, and rest on the very high temperature time up to more than 15 minutes.Coating constituent is count by weight percentage: through the organic resin 15%～45% of graft modification, inorganic salt filler 15%～50%, sclerosing agent 0.1%～3%, solvent 3%～20%.By using high temperature resistant grafting organic resin, mean the silane (such as diethylin MTES) of organic resin and amino-contained, or with dimethyldiethoxysilane (dimethyldiethoxylsilane, DMDES), and this organic resin is containing aluminum, silicon, zirconium, magnesium, calcium, titanium, at least one above grafting property organic material of ferrum plasma, insulating heat-conduction material is formed by modification, and add one or containing two or more inorganic salt filler mixing manufacture coating, can promote resistance to moment further is warming up to the quality of high-temperature coatings, and it is effectively improved the combination property of coating, coating splitting resistance under the high temperature conditions particularly can be substantially improved, compactness, conduction of heat and anti-flammability, it is widely used in the encapsulating of various high temperature resistant components and parts etc..
High temperature resistant organic resin, with containing aluminum, silicon, zirconium, magnesium, calcium, titanium, ferrum plasma such as epoxy silicone resin, poly-ammonia organic siliconresin, organosilicon phenolic resin, at least one above composition graft modification of boron bakelite resin, then carries out hybrid process with other components；It is processed according to conventional coating processing technology, can be according to product category, technological requirement, adjust each component ratio, component particle diameter proportioning, dope viscosity, hardening time, solidification temperature, painting color are adjusted optimizing, meet actual product, technological requirement.
