Embodiment 1

[0020] Protective paint in the present embodiment comprises following composition:

[0021] The film former is used to form a film after the coating is applied to the product, and the film former is preferably styrene-butadiene-styrene block copolymer resin SBS. In a wide range of film-forming materials, the above-mentioned film-forming material components can promote the coating to form a dense protective film on the surface of the product, and this protective film can prevent the product from contacting with the corrosive environment in the ocean, thereby improving the protection against the product. The protective effect of the product, so the selection of the above-mentioned film-forming material belongs to the inventive selection invention. The weight part of the film-forming substance is preferably 30-50 parts.

[0022] The ultraviolet absorber, the weight part of the ultraviolet absorber is preferably 2.5 parts to 4.5 parts. Since the product is inevitably exposed to ...

Embodiment 2

[0033] According to the above mass formula components, weigh 30 parts of film-forming resin (styrene-butadiene-styrene block copolymer SBS), 2.5 parts of ultraviolet light absorber (octylated diphenylamine OD), corrosion inhibitor (Amino trimethylene phosphonic acid) 5 parts, defoamer (Defom8700) 0.3 parts, leveling agent (Levelol495) 0.5 parts, organic soil 2 parts, pigment and filler (iron oxide red) 15 parts, heat stabilizer (February 0.3 parts of dibutyltin silicate), 60 parts of solvent (a mixed solvent mixed with xylene and butyl acetate at a volume ratio of 6:4), after mixing and stirring evenly, grind in a sand mill to a fineness of about 35 μm, that is The peelable protective coating for the ocean transportation of the export mechanical products is obtained.

Embodiment 3

[0035] According to the above mass formula components, weigh 50 parts of film-forming resin (styrene-butadiene-styrene block copolymer SBS), 4.5 parts of ultraviolet light absorber (dioctyl diphenylamine ODA), corrosion inhibitor (Dicyclohexylamine oleate) 10 parts, defoamer (Defom8700) 0.8 parts, leveling agent (Levelol495) 1 part, organic soil 5 parts, pigment and filler (iron oxide red) 30 parts, heat stabilizer (February 0.7 parts of dibutyltin silicate), 80 parts of solvent (a mixed solvent mixed with xylene and butyl acetate at a volume ratio of 6:4), after mixing and stirring evenly, grind in a sand mill to a fineness of about 35 μm, that is The peelable protective coating for the ocean transportation of the export mechanical products is obtained.

Abstract

The invention relates to strippable protective coating, which is used for ocean transportation of mechanical products. The strippable protective coating comprises the following components in parts by mass: 30-50 parts of film former, 2.5-4.5 parts of ultraviolet absorber, 5-10 parts of corrosion inhibitor, 0.3-0.8 part of defoaming agent, 0.5-1 part of flatting agent, 2-5 parts of organic bentonite, 15-30 parts of pigment filler, 0.3-0.7 part of thermal stabilizer, and 60-80 parts of solvent, wherein the film former is a styrene-butadiene-styrene segmented copolymer. After forming films, the strippable protective coating has excellent salt spray corrosion resistance and ultraviolet aging resistance, has stable property in an ocean environment, and can solve the protection problem of mechanical products in ocean transportation.

Description

technical field [0001] The invention discloses a peelable protective coating for marine transportation of export mechanical products, which relates to the field of peelable protective coatings, in particular to the field of peelable protective coatings for marine transportation. Background technique [0002] After the export mechanical products are transported by sea, due to the influence of the harsh marine atmospheric corrosion climate, the metal parts of the mechanical products are extremely prone to corrosion; although the surface of the exported mechanical products has been coated with protective and decorative coatings, due to The coating system and products used are only designed according to the continental climate and cannot withstand the corrosion of the harsh ocean atmosphere. After the export machinery products arrive at the destination, the surface corrosion is also very serious, which seriously affects the product quality; in order to ensure the quality of expor...
