Background technique
Currently, business and office building at home and abroad, more and more fire proof constructions and demand and application, especially super
Skyscraper, in high-altitude due to factors such as air-flows, fireproof is needed it is more next stringent, in addition, processing building trade, metallurgy,
Under the environment such as aerospace, all there is hot environment, need to carry out fireproof demand, in order to preferably carry out fire-proof high-temperature resistant
Can protection, can carry out fire-proof and thermal-insulation, but existing fire proofing material its high temperature resistance in substrate surface brushing fire proofing material
Difference, poor to the thermal insulation of internal material, traditional fire prevention mainly passes through is prevented fires using carbon fiber fire-retardant fireproof cotton, is passed through
It is laid with anti-guncotton in isolated area, is prevented fires using performances such as the heat-resisting of anti-guncotton, heat resistanceheat resistants, but the material under high temperature environment can
Enough maintain heat-insulated duration shorter, experiment show the lower 1 hour weight-loss ratio of this carbon fiber cotton high temperature up to 90% or more, it is real
Border occur fire when, if can not timely fire extinguishing cooling, carbon fiber cotton can be gradually consumed as covering material, furthermore existing
Some fireproof coatings, it is single to equally exist preventing principle, can not carry out effective prolonged protection, and the resistance in coating
It is excessively high to fire ingredient breakdown temperature, decomposes flame retarding reaction and extends, can not quickly be decomposed fire-retardant, reaches effective fire prevention mesh
, and its reaction char volume is small, poor to the isolation effect of the intensity of a fire, the gas that internal last decomposition generates is easy to rise film
It is quick-fried, flameproof effect can not be played, and fire resistant coating is isolated by fire source, but inner substrate is due to the poor heat resistance of coating, it may appear that
The case where disintegrating calving prior to coating.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of inorganic high-temperature resistant fire prevention painting
Material improves whole heat resistance, while cooperating between different metal by a variety of alloying elements by chemical reaction mixing
It is merged in the condition of high temperature, forms polynary corrosion resistant fireproof coating.
In order to achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of inorganic high-temperature resistant fireproof coating, it includes following component in parts by mass:

Min heating rate is heated to 70-80 DEG C and is stirred to react 5-5.5h, obtains reaction product, room is then chilled in 3-5min
Temperature；
The speed of agitator is initially 300r/min, increases by 100 turns of revolving speed per minute later, until revolving speed reaches
1800-2000r/min, it is lasting to stir；
The reaction product is filtered by vacuum, obtained suction filtration product is soluble in water and is dispersed by cyclone, warp
Centrifuge washing, drying process, after cooling to obtain the final product.
Preferably, fineness >=7.5HGM of the bentonite clay particle, unit " HGM " indicate Hai Geman (Hegman) grade
Fineness is divided into 0-8 grades, and Hegman value is changed stepwise by 0-8, in which: 0Hegman=100 microns, 2Hegman=75 is micro-
Rice, 4Hegman=50 microns, 6Hegman=25 microns, 8Hegman=0 microns；
The average grain diameter of the igneous rock powder is 60 microns, and the Tungsten Powder Size is 80-100 mesh.
The present invention further provides the preparation method of above-mentioned inorganic high-temperature resistant fireproof coating, includes the following steps:
(1) 8-15 parts of polyamidoimides are added in 20-26 parts of epoxy-modified inorganic polysiloxanes, and are dispersed with stirring,
Obtain epoxy-modified inorganic polysiloxane dispersion liquid；
(2) by 5-6 parts of titanium dioxide, 2-10 parts of tungsten powders, 10-12 parts of magnesia, 1-4 parts of aluminum oxides, 4-8 parts it is swollen
Profit soil, 25-30 parts of igneous rock powder, 2-8 parts of nanometer silicon carbides are added sequentially to epoxy-modified inorganic polysiloxane point obtained by step (1)
In dispersion liquid, and it is dispersed with stirring；
