Description

A kind of high heat-conductive coating of exhaust equipment
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of high heat-conductive 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.
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 high heat-conductive coating of exhaust equipment.
The present invention is achieved by the following technical solutions:
A kind of high heat-conductive coating of exhaust equipment, is made up of the raw material of following weight portion: organic siliconresin 15-18, propylene Acid resin 55-60, polyimides 12-15, aluminium sesquioxide 2-3, Zirconium orthosilicate. 1-2, expansion Muscovitum 2.8-4, dimethylbenzene 8-10, fat Fat acid polyethylene glycol ester 0.5-0.7, flyash 15-18, aluminium powder 5-7, glycerol 0.8-1, styrene 12-14, azo two isobutyl Nitrile 1.2-1.4, bentonite 2.4-2.6, aluminium nitride 3.3-4, sheet mica 1.8-2.4, silane coupler a174 0.2-0.3, nothing Water-ethanol is appropriate.
Described a kind of high heat-conductive coating of exhaust equipment, is made up of step in detail below:
(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 After be added to flyash in the deionized water that weight ratio is 10-20:100 to be sufficiently stirred for forming dispersion liquid, by bentonite with 3-4 times The deionized water of amount is diluted to A, and aluminium powder is added in the triethanolamine of 2-3 times amount be stirred into B, A and B mixing is sufficiently stirred for Form C；
(2) in the case of quickly stirring, C is added in flyash dispersion liquid, adds aluminium nitride, sheet mica and silane even Connection agent a174 is sufficiently stirred for being formed D, then reacts 2-3h, cooled and filtered at D is warming up to 60-90 DEG C under air-proof condition, adds In baking oven, at 100-110 DEG C, drying and crushing is standby；
(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) be sequentially added into organic siliconresin in high-speed stirred dispersion machine, prepared by acrylic resin, polyimides, step (3) Product and dimethylbenzene first stir 8-12min with 500r/min, add fatty acid polyethylene glycol ester and stir 12-with 800r/min 15min, is eventually adding glycerol and surplus materials stirs 10-15min with 200r/min, stands 4-6min i.e. after having stirred Can.
The invention have the advantage that the present invention utilizes acid corrosion flyash to improve its specific surface area, increase porosity so that it is more Good is coated with aluminum, has stopped aluminum surface and chemical reaction occurs, and caking property between improve, non-oxidizability, corrosion-resistant With the performance such as heat conduction, then carry out styrene monomer emulsion cladding with it for core so that clad ratio is high, and covered effect is good, stability Height, and also avoid aluminium powder routine cladding easily cause in matrix resin, be easily generated between trace, unordered polymerization aluminium powder friendship The problem of connection bonding；The coating that the present invention prepares has good oil resistivity, resistance to water, and coating adhesion is good, and good toughness is led Hot good, antiseptic property is excellent, is worthy to be popularized.
