Abstract
The present invention provides a preparation method of modified composite powder coating. The nano-barium sulfate of 50 percent and with a surface treated by a silane coupling agent and an average particle size of 25nm is milled for 2 hours in a ball mill; the composite coating is painted on the surface of a steel plate treated by sandblasting; the pressure is 0.3MPa; the coated steel plate is then arranged in a stove for heat treatment for 20 minutes to 30 minutes at a temperature between 340 DEG C and 380 DEG C. Then the steel plate is plasticized to get the coating of flat and smooth surface. The present invention has the advantages of overcoming the flow phenomenon in plasticization process and improving the stress-corrosion resistance of the coating.
Description
Technical field
The present invention relates to a kind of method of producing modified compound powder paint.
Background technology
The epoxide powder coating that uses can not satisfy the requirement for anticorrosion of oil well pipe as corrosion protection coating comprehensively at present.Polyphenylene sulfide melt viscosity is low excessively, and self-leveling can be poor, reduces coating antiseptic erosion ability.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, propose a kind of method of producing modified compound powder paint.
Technical scheme of the present invention is: a kind of method of producing modified compound powder paint, it is characterized in that: through 50% the nano barium sulfate of silane coupling agent surface treatment median size 25nm, in grinding in ball grinder after 2 hours, composite coating is coated with is contained on the surface of steel plate of sandblasting, pressure 0.3Mpa is placed on steel plate after the application in the baking oven again, heat-treats 20-30 minute at 340-380 ℃, carry out plastics processing, promptly obtain surfacing, slick coating.
The present invention has the following advantages: overcome thermoplastification stage sagging phenomenon, improve the coating anti-stress corrosion performance.
Embodiment
Embodiment: a kind of method of producing modified compound powder paint, 50% nano barium sulfate through silane coupling agent surface treatment median size 25nm, in grinding in ball grinder after 2 hours, composite coating is coated with is contained on the surface of steel plate of sandblasting, pressure 0.3Mpa is placed on steel plate after the application in the baking oven again, heat-treats 20-30 minute at 340-380 ℃, carry out plastics processing, promptly obtain surfacing, slick coating.
