Description

A kind of exhaust equipment Environmentally-frieantirust antirust paint
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of exhaust equipment Environmentally-frieantirust antirust paint.
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 exhaust equipment Environmentally-frieantirust antirust paint.
The present invention is achieved by the following technical solutions:
A kind of exhaust equipment Environmentally-frieantirust antirust paint, is made up of the raw material of following weight portion: carbonyl iron dust 2.5-3, poly-second Enol butyral 15-20, tripolyphosphate calcium 1-1.5, flyash 20-22, aluminium powder 6-8, epoxy resin E4435-40, epoxy resin E2055-60, polyvinyl alcohol Oleum Ricini 2-3, butyl acetate 16-20, hexamethylene diamine 1-2, polyamide 2-3, styrene 12-14, azo Bis-isobutyronitrile 1.2-1.4, poly aluminium iron silicate 0.7-1, isobutene. triethoxysilane 0.5-0.7, polymerization ferrophosphorus powder 2.4-3, plant Acid 1.7-2, urea propyl trimethoxy silicane 0.5-0.6, bismuth germanium oxide 0.5-0.8, aluminate coupling agent 0.3-0.4, dehydrated alcohol In right amount.
