Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of heat-resisting chemicals-resistant coating of exhaust equipment.
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.
