Alkyd resin coating for industrial outer wall and preparation method thereof

Abstract

The invention discloses an alkyd resin coating for an industrial outer wall. The alkyd resin coating comprises, by weight parts, 60-68 parts of drying oil alkyd resin, 20-50 parts of epoxy modified alkyd resin, 15-30 parts of acyclic acid modified alkyd resin, 2-4 parts of propylene glycol monomethyl ether acetic ester, 5-10 parts of propylene glycol, 5-10 parts of alcohol etherification melamine resin, 2-8 parts of urea resin, 1-3 parts of 2-amino-2-methyl-1-propanol, 20-25 parts of carboxymethyl cellulose, 1-3 parts of silane coupling agent, 1-4 parts of sodium dodecylbenzene sulfonate, 1-3 parts of polyoxyethylene polyoxypropylene ether, 1-2 parts of wetting agent, 1-3 parts of solydimethyl siloxane, 0.5-1.5 parts of preservative, 1-2 parts of hydroxypropyl guar gum, 40-60 parts of water, 5-20 parts of amyl acetate, 5-10 parts of super fine calcium carbonate, 2-8 parts of magnesium silicate, 6-10 parts of kaolin and 2-8 parts of china clay. The invention further discloses a method for preparing the alkyd resin coating for the industrial outer wall. The alkyd resin coating for the industrial outer wall is good in adhesive force and excellent in corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of alkyd resin coatings, in particular to an alkyd resin coating for industrial exterior walls and a preparation method thereof. Background technique [0002] At present, alkyd resin coatings for industrial exterior walls on the market are generally only used for decoration, and the effect is good, but the adhesion and corrosion resistance are poor. After being washed by rain, the paint film will cause cracking, peeling or whole If it peels off, rainwater will seep into the wall, corrode the wall, and seriously endanger industrial production. Contents of the invention [0003] The invention provides an alkyd resin coating for industrial exterior walls and a preparation method thereof, which has good adhesion, excellent corrosion resistance, and does not produce spots or blackening even in extremely harsh environments. [0004] A kind of alkyd resin coating for industrial exterior wall proposed by the pres...
