Embodiment 1

[0026] Get 30 parts by weight of epoxy resin, 20 parts by weight of polyurethane resin, 8 parts by weight of dolomite, 4 parts by weight of aluminum nitride, 3 parts by weight of aluminum oxide, 2 parts by weight of carbon black, 0.5 parts by weight of modified imidazole, 50 parts by weight of n-butanol ~96 parts by weight.

[0027] The production process of Example 1 is as follows: first add the resin raw materials after quantitative proportioning to the reactor and add a quantitative diluent to fully dissolve and stir. It takes 2 hours of stirring to fully dissolve the resin. After the resin raw materials are completely dissolved Put it into a stainless steel container for high-speed dispersion, while adding pigments and inorganic fillers in sequence. It needs to be dispersed for one hour, and then put into the grinder and grinded repeatedly four times. Mix the ground paint with modified imidazole, stir evenly at a speed of 800-1000 r / min at room temperature, and obtain the...

Embodiment 2

[0029] Take 40 parts by weight of epoxy resin, 15 parts by weight of polyurethane resin, 10 parts by weight of dolomite, 6 parts by weight of boron nitride, 2 parts by weight of aluminum oxide, 2 parts by weight of aluminum nitride, 3 parts by weight of carbon black, 1.5 parts by weight of modified imidazole Parts by weight, 50-96 parts by weight of propanol are diluents.

[0030] The production technology of embodiment 2 is the same as embodiment 1.

Embodiment 3

[0032] Get 60 parts by weight of epoxy resin, 20 parts by weight of polyurethane resin, 7.5 parts by weight of dolomite, 4.5 parts by weight of aluminum nitride, 1.5 parts by weight of boron nitride, 1.5 parts by weight of aluminum oxide, 4 parts by weight of carbon black, 2.5 parts by weight of modified imidazole parts by weight, 50-96 parts by weight of neopentyl alcohol.

[0033] The production technology of embodiment 3 is the same as embodiment 1.

[0034] The method of using this anti-corrosion and heat-dissipating coating is: degrease and decontaminate the surface of the product or equipment that needs to be sprayed with anti-corrosion and heat-dissipating coating, pour the coating in the above embodiment into the spray gun, set the pressure of the spray gun to 0.4MPa, and aim at the target On the surface, the distance between the two is 10-20cm, spray back and forth 2-3 times until the paint evenly covers the surface of the object. The coating is uniform and shiny, an...

Abstract

The invention relates to anticorrosive heat dissipation coating. The anticorrosive heat dissipation coating is produced through the following raw materials of, by weight, 30 to 60 parts of epoxy resin, 10 to 20 parts of polyurethane resin, 15 to 30 parts of inorganic filler, 2 to 4 parts of carbon black, 0.5 to 2.5 parts of modified imidazole and 50 to 96 parts of alcohol diluent. A production method for producing the anticorrosive heat dissipation coating comprises the steps of step 1, accurately weighing the epoxy resin, the polyurethane resin and the diluent to be uniformly mixed to form a resin solution; step 2, taking the all mass of resin solution in the step 1 to be mixed with the carbon black and the inorganic filler to be poured into a grinding machine to be ground and dispersed and uniformly stirring at the speed of 800 to 1000 revolutions every minute at room temperature; step 3, enabling coating and the modified imidazole in the step 2 to be mixed with each other, uniformly stirring at the speed of 800 to 1000 revolutions every minute at room temperature and obtaining the target coating after stabilization.

Description

technical field [0001] The invention relates to an anti-corrosion heat-dissipating coating and a preparation method thereof. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. [0003] With the advent of a new round of industrial age, modern electronic equipment is highly integrated, and electronic components have more stringent and urgent requirements for anti-corrosion and heat dissipation performance. However, in actual technology, it is difficult to prepare a corrosion-resistant coating with good thermal conductivity and high heat resistance by a single m...
