Description

A kind of exhaust equipment high wear resistance coatings
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of exhaust equipment high wear resistance coatings.
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 high wear resistance coatings.
The present invention is achieved by the following technical solutions:
A kind of exhaust equipment high wear resistance coatings, is made up of the raw material of following weight portion: flyash 16-18, aluminium powder 7-9, Epoxy modified silicone resin 78-85, toluene 12-15, zirconium dioxide 1-2, silicon nitride 4-5, polyester resin 12-15, dimethyl Silicone oil 0.4-0.5, sodium hexameta phosphate 0.4-0.5, styrene 12-14, azodiisobutyronitrile 1.2-1.4, titanate coupling agent 0.3-0.35, polysorbas20 0.1-0.2, maleic anhydride 0.7-0.9, aluminate coupling agent 0.14-0.2, calcium oxide 2.5-3.5, nothing Water-ethanol is appropriate.
Described a kind of exhaust equipment high wear resistance coatings, is made up of step in detail below:
(1) the flyash concentrated hydrochloric acid of 2-3 times amount is soaked 16-20h, take out and be washed with deionized to filtrate in neutral after bake Dry, it is supernatant liquid by calcium oxide deionized water dissolving, then flyash is added to wherein and is passed through carbon dioxide reaction 30- 50min, filtering drying；
(2) flyash aluminium powder, dimethicone, step (1) prepared and aluminate coupling agent are added in colloid mill grind, and grind Mill is rear and titanate coupling agent, polysorbas20, maleic anhydride mix, and stirs 40-60min, be then added to make at 60-80 DEG C Granule made by grain machine, dries；
(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 epoxy modified silicone resin, product prepared by polyester resin, step (3) Thing and toluene first stir 12-15min with 600r/min, add sodium hexameta phosphate and stir 5-8min with 800r/min, finally add Enter dimethicone and surplus materials stirs 10-15min with 500-800r/min, after having stirred, stand 4-6min.
The invention have the advantage that the present invention utilizes acid corrosion flyash, improve surface contact point and activation point, and enter One step calcification improves its resistance and reactivity, and the compounding aluminum surface of not only having stopped of aluminium powder occurs chemical reaction, and improves and fill out The intensity of material and the affinity of resin and the compatibility, then use cladding maleic anhydride, improve cinnamic clad ratio, effective, And improve absorption at break energy and hot strength, also efficiently solve aluminium powder in matrix resin, be easily generated trace, unordered The problem of cross-linkable adhesive between polymerization aluminium powder；The invention provides a kind of high wear resistance coatings for exhaust equipment, the most resistance to Mill performance is high, and film smooths good brightness, and high-low temperature resistant difference is good, the most easy to crack, and ageing resistance is strong, dry shrinkage volume Little, it is worthy to be popularized.
