Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of corrosion resistant coating for exhaust equipment surface.
Background technology
The surface of shell of exhaust equipment can be brushed different pigment and guarantee that housing is without damage, the use longevity of extension device
Life.Aluminum pigment is widely used in traditional solvent based coating and oil due to its special metallic luster and " changeable colors along with angle " effect
Mo Zhong.It is big that it has excellent metallic effect demand, and flake aluminum has good reflection light and the energy of reflective thermal radiation
Power, forms continuous print metal film in coating, can reflect visible ray, ultraviolet and infrared ray.Reflection to visible light full spectrum
It is silvery white in color so that it is there is good decoration performance, ultrared reflection is made it have the heat-insulating property of reflective thermal radiation, and
To the reflection of ultraviolet then can protective coating not by ultraviolet damage, extend the life-span of coating.Due to the performance of pure aluminum own
Vivaciously, aluminium powder specific surface area is big, and the most surface treated aluminium powder is easy to reunite, and aluminium powder occurs chemistry anti-with other media
Should easily lose original performance.Common aluminium powder pigment easily reacts with water, therefore can not directly use, with acid in water paint again
Property or alkaline medium contact time be easily corroded, corrosion can make the glossiness of aluminium powder pigment decline, and color is gloomy, the hydrogen of release
The biggest pressure is formed, consequently, it is possible to there is the danger of blast in container.Therefore to adapt to different application demands, improve aluminum
The weatherability of powder, widens application, needs aluminium powder is carried out surface modification, makes powder body in preparation process and last handling process
In be in high degree of dispersion state, be current aluminium powder pigment research important topic.
Having carried out the research of styrene polymerization cladding aluminium powder in " research of styrene polymerization cladding flake aluminum ", author adopts
Being coated with aluminium powder under the system of dehydrated alcohol with refined styrene, result shows along with the increase of monomer consumption, slow
Releasing efficiency to be gradually increased, conversion ratio, clad ratio, coating efficiency are had the biggest by the quality of the quality of monomer, consumption and aluminium powder
Impact, the quality stability of product is the highest, and the corrosion resistant effect played in coating also needs to improve.The thing that flyash is good
Reason, chemical characteristic make it have and well apply potential quality, add flyash and be not only able to strengthen the mobility of coating in coating,
The pore structure of system can also be improved, improve the function of coating.The present invention utilizes aluminium powder and flyash to be mixed with high-alumina fly
Coal ash microsphere, corrosion-resistant, impact strength, the erosion-wear-resisting performance that play in coating can play the biggest raising, but
It is that to be directly added into the compatibility the highest, the combination property of material can be substantially reduced.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of corrosion-resistant for exhaust equipment surface
Coating.
The present invention is achieved by the following technical solutions:
A kind of corrosion resistant coating for exhaust equipment surface, is made up of the raw material of following weight portion: acrylic resin

(1) the flyash concentrated sulphuric acid of 3-5 times amount being soaked 8-10h, it is neutrality that taking-up is washed with deionized to filtrate, dries
Standby;Again standby flyash, calcium oxide, iron sesquioxide mix homogeneously ball milling are become fine powder, add polyvinyl acetate breast
Mixture adhesive aggregation is coated on aluminium powder surface by liquid together, dries, then is placed in sintering furnace under inert atmosphere in 500-550 DEG C
Calcining 30-45min, spraying into quickly cooling in water after terminating, to make spherical powder standby;
(2) by inorganic silicon colloidal sol, the PVA mixed deionized water dissolving share 4-5 times amount, ball prepared by step (1) is added
Shape powder mix homogeneously, heats while stirring to moisture evaporation, standby after natural cooling;
(3) in equipped with the flask of agitator add step (2) prepare product, dehydrated alcohol, styrene, in the protection of nitrogen
Under, start agitator heat make bottle in temperature control, at 70 DEG C, to be slowly added dropwise initiator azo two at this temperature
Isopropyl cyanide, then constant temperature keeps this temperature to continue reaction 3-3.5h, and reaction cools down after terminating, reactant mixture methanol extraction,
Filtering, filter cake is placed in that to dry, pulverize 300-400 mesh sieve in 50 DEG C of vacuum drying ovens standby;
(4) in high-speed stirred dispersion machine, be sequentially added into acrylic resin, product prepared by amino resins, step (3) and acetic acid
Butyl ester first stirs 8-12min with 500r/min, adds poly-propionic acid amide. and stirs 15-18min with 1300r/min, is eventually adding poly-
Dimethyl siloxane and surplus materials thereof stir 10-15min with 500-800r/min, stand 4-6min after having stirred.
The invention have the advantage that the present invention utilizes calcium oxide, iron sesquioxide at high temperature to produce crystalline phase by flyash bag
Overlaying on aluminium powder surface, quickly cooling makes spherical powder, improves the mobility of powder, deposition efficiency etc., has stopped aluminum surface and has occurred
Chemical reaction, then use Ludox to carry out inorganic coating so that it is surface forms adsorption layer, then carries out styrene monomer with it for core
Emulsion is coated with so that clad ratio is high, effective, improves spherical powder dispersibility, permeability in resin matrix, and also has
Effect solving aluminium powder is easily generated the problem of cross-linkable adhesive between trace, unordered polymerization aluminium powder in matrix resin;Present invention profit
Improve the performance of coating with the corrosion resistance characteristic of aluminium powder, and also have low-carbon (LC), fire-retardant, adhesive force strong, freeze-thawing resistant, aging resistance,
The effects such as film is flexible, hardness is high, are current like product irreplaceable novel environment friendly products, and application prospect is good.
