Abstract
The present invention provides a kind of organo-mineral complexing water paints and preparation method thereof, are prepared by following raw material：Water, iron powder, 1,3,5 benzenetricarboxylic acid, hydrofluoric acid, nitric acid, N, N dimethylformamides, sodium metasilicate, non-ionic emulsifier liquid, styrene-acrylic emulsion, silicon dioxide gel, nano-titanium dioxide dispersion, sodium acetate, antifoaming agent, levelling agent, dispersant, talcum powder.Compared with prior art, the present invention does inorganic filming substance with water-soluble metasilicate, is then compounded with metal-organic framework material (MOF), obtains organo-mineral complexing water paint.Since metal-organic framework material has, thermal stability is good, pore passage structure is orderly, and in hole and surface can carry out many peculiar properties such as modified with functional group, so that water paint is with good stability, high temperature resistance and adhesive force.
Description
Technical field
The present invention relates to technical field of coatings more particularly to a kind of Organic-inorganic composite water paint and preparation method thereof.
Background technology
With the development of industrial technology, high-temperature-resistant thermal-insulation insulating moulding coating comes into being, and water paint is many excellent because of its
Performance and be concerned, high temperature resistant field use have considerable development trend.Currently, water paint can be coated in surface temperature
It spends in higher level, such as oven, electromagnetic oven, heat exchanger high temperature metal parts, but its adhesive force and high temperature resistant
Performance needs to further increase.
In general, it is multiple to be broadly divided into organic high temperature-resistant coating, refractory inorganic paint and organic and inorganic for high-temperature resistant coating
Close high-temperature resistant coating.Complex fire resistant coating is broadly divided into two classes, and one kind is to do film forming matter with organic matter (resin or lotion), so
A large amount of mineral powder is added in system afterwards and does color stuffing, i.e. inorganic component.Another kind of is the nothing using inorganic component as substrate
The high temperature resistance of machine component is preferable, can generally bear 400~1000 DEG C of temperature, but the poor curing performance that forms a film, water resistance,
Adhesive force, impact strength are poor, and therefore, into inorganic component, addition organic siliconresin solves the above problems, and obtains organic-nothing
Machine composite coating.
In the prior art, application No. is 01136262.6 Chinese patent literature, to report a kind of nano combined high temperature resistant anti-
Fiery coating, including nanometer silicon carbide, nano silicate clay, phosphate, nanometer aluminium silicate and high-molecular organic material.But
The adhesive force of the high-temp.-resisting fire-proof composite nano paint is poor, and the high-temperature behavior needs to be further improved.
Invention content
Present invention solves the technical problem that being to provide a kind of Organic-inorganic composite water paint and preparation method thereof, tool
There are good high temperature resistance and stronger adhesive force.
In view of this, the present invention provides a kind of Organic-inorganic composite water paint, prepared by following raw material：Water 25~45
Parts by weight, 1~3 parts by weight of iron powder, 1,3,5- benzenetricarboxylic acid, 2~6 parts by weight, 0.05~0.1 parts by weight of hydrofluoric acid, nitric acid 0.05~
0.1 parts by weight, 0.2~0.6 parts by weight of n,N-Dimethylformamide, 30~40 parts by weight of sodium metasilicate, non-ionic emulsifier liquid 0.2~
0.3 parts by weight, 2~8 parts by weight of styrene-acrylic emulsion, 5~10 parts by weight of silicon dioxide gel, 3~8 weight of nano-titanium dioxide dispersion
Measure part, 0.1~0.2 parts by weight of sodium acetate, 0.15~0.3 parts by weight of antifoaming agent, 0.15~0.3 parts by weight of levelling agent, dispersant 1
~1.5 parts by weight, 10~13 parts by weight of talcum powder.
Preferably, it is prepared by following raw material：30~40 parts by weight of water, 2~3 parts by weight of iron powder, 1,3,5- benzenetricarboxylic acid 4~5
Parts by weight, 0.05~0.1 parts by weight of hydrofluoric acid, 0.05~0.1 parts by weight of nitric acid, 0.3~0.5 weight of n,N-Dimethylformamide
Part, 30~35 parts by weight of sodium metasilicate, 0.25~0.3 parts by weight of non-ionic emulsifier liquid, 3~5 parts by weight of styrene-acrylic emulsion, silica
6~8 parts by weight of colloidal sol, 4~6 parts by weight of nano-titanium dioxide dispersion, 0.15~0.2 parts by weight of sodium acetate, antifoaming agent 0.2~
0.3 parts by weight, 0.15~0.2 parts by weight of levelling agent, 1~1.5 parts by weight of dispersant, 11~13 parts by weight of talcum powder.
Correspondingly, the present invention also provides a kind of preparation method of Organic-inorganic composite water paint, include the following steps：It will
Iron powder, 1,3,5- benzenetricarboxylic acids, hydrofluoric acid, nitric acid and n,N-Dimethylformamide carry out polymerisation, obtain under hydrothermal conditions
Metal-organic framework material；Nano-titanium dioxide dispersion and talcum powder are added into sodium silicate solution, adds after stirring for the first time
