Abstract
The invention relates to a special coating, in particular to a high temperature resistant strippable anti-corrosion coating and a preparation method thereof. The coating consists of a film forming agent, an auxiliary agent and a solvent, and the compositions in percentage by weight are as follows: 12 to 17 percent of the film forming agent, 5 to 10 percent of the auxiliary agent, and 73 to 83 percent of the solvent. The concrete preparation method comprises the following steps: the film forming agent, the auxiliary agent and the solvent are mixed according to the weight ratio, and then are stirred at normal temperature in a closed container to dissolve for 30 minutes to obtain a product. The coating takes a high molecular polymer as a film forming material, has the advantages of good acid, base and salt resistances, excellent toughness, remarkable high temperature resistance, easiness for coating, convenient unsealing, and no pollution to the surface of metal after a solidified coating film is stripped; in addition, the stripped coating film can be repeatedly used after the treatment.
Description
Technical field
What the present invention relates to is a kind of speciality coating, relates in particular to a kind of high temperature resistant strippable anti-corrosive paint and preparation method thereof.
Background technology
The corrosion of metallic substance in atmospheric environment is the most general, especially under some hot environments.Common safeguard procedures are applying coatings, for removing paint film, often adopt organic solvent dissolution to film in use, handle with buck, perhaps handle with physical methods such as bamboo cutter, scraping blades, but these methods are difficult to eliminate and film, and diminish the surface, take a lot of work and time-consuming.
Summary of the invention
The objective of the invention is to overcome the shortcoming of traditional coating, a kind of high temperature resistant strippable anti-corrosive paint is provided.
Technical scheme of the present invention is: high temperature resistant strippable anti-corrosive paint is by membrane-forming agent, auxiliary agent and solvent composition, and each components by weight is:
Membrane-forming agent 12～17%
Auxiliary agent 5～10%
Solvent 73～83%
Wherein membrane-forming agent is made up of Vinylite and vinylbenzene-divinyl-styrene block copolymer (SBS), and each components by weight is:
Vinylite 90～95%
Vinylbenzene-divinyl-styrene block copolymer (SBS) 5～10%
Vinylbenzene-divinyl-styrene block copolymer (SBS) is linear YH-792 (S/B=40/60);
Auxiliary agent is made up of dibutyl phthalate (DBP), active nano level lime carbonate, stearylamine, lanolin, dihydroxyphenyl propane, triethyl-phosphite and dibutyl tin laurate, and each components by weight is:
Dibutyl phthalate (DBP) 60～65%
Active nano level lime carbonate 13～17%
Stearylamine 5～8%
Lanolin 5～8%
Dihydroxyphenyl propane 2～5%
Triethyl-phosphite 0.5～1.5%
Dibutyl tin laurate 0.5～1.5%
The median size of active nano level lime carbonate is 20～50nm;
Solvent is made up of pimelinketone and tetrahydrofuran (THF), and each components by weight is:
Pimelinketone 50～60%
Tetrahydrofuran (THF) 40～50%
The concrete preparation process of high temperature resistant strippable anti-corrosive paint is:
(1), according to above-mentioned weight ratio, join in the pimelinketone after Vinylite, dihydroxyphenyl propane, triethyl-phosphite mixed;
(2), by weight, vinylbenzene-divinyl-styrene block copolymer (SBS), active nano level lime carbonate, stearylamine, lanolin are joined in the tetrahydrofuran (THF) after mixing;
(3), the solution of gained in step (1) and (2) mixed and stir, add DBP, dibutyl tin laurate by weight, stirring at normal temperature promptly gets product after 30 minutes.
The invention has the beneficial effects as follows:
(1), the present invention is filmogen with the high molecular polymer, and added lanolin as inhibiter, has good acid-and base-resisting, salt performance;
(2), added vinylbenzene-divinyl-styrene block copolymer (SBS), active nano level lime carbonate as plasticising toughner, the coating rete has excellent toughness, thereby plays shockproof effect such as scratch resistant;
(3), because the adding of triethyl-phosphite (TEP) and dihydroxyphenyl propane thermo-stabilizer, the resistance to elevated temperatures of coating rete is remarkable, can be applicable to the temporary protection of metallic surface under the hot environment;
(4), this coating is easy to apply, and provides easier opening, it is pollution-free that the coating rete after the curing is peeled off the metallic surface, back, and the coating rete that peels off is reusable after treatment.
