[01] The present disclosure relates to the field of anticorrosive coatings for industrial use, in particular to a high-flash-point polyurethane-based anticorrosive finishing coat for industrial use.
[02] Anticorrosive materials can inhibit the chemical corrosion and electrochemical corrosion of a target object. The anticorrosive materials commonly used in installation engineering mainly include various organic and inorganic coatings, glass fiber reinforced plastics, rubber products, inorganic plates, etc. The coatings can be divided into two categories: oil-based coatings (using dry oils as afilm-forming substance) and resin-based coatings (using synthetic resins as a film-forming substance). Coatings are applied on the surface of an object in a certain way, and cured to form a thin coating layer to protect the surface of the object. In this way, the coatings can help prevent pipelines and metal structures from the corrosion of chemical atmosphere, acid, alkali and other media.
[03] At present, a polyurethane-based anticorrosive finishing coat is mainly used for industrial anticorrosion. A two-component polyurethane-based anticorrosive finishing coat is composed of a synthetic resin as a base material, a coloring pigment and a curing agent, and has good chemical resistance and water resistance. However, the polyurethane-based anticorrosive finishing coat has a relatively low flash point, and the flash points of an A component and a B component are both below 25 degrees. When the environment reaches a certain temperature, a mixture of a finishing coat vapor and the surrounding air, once in contact with an open flame, will cause a flashover. Therefore, the polyurethane-based anticorrosive finishing coat is dangerous, and is unfavorable for production, transportation and use.
[04] It can be seen that there is an urgent need to provide a high-flash-point polyurethane based anticorrosive finishing coat for industrial use.
[05] In the view of the above problems, the high-flash-point polyurethane-based anticorrosive finishing coat for industrial use of the present disclosure is simple to prepare and convenient to use. The present disclosure increases the flash point through a certain proportion of a flash point enhancer to open up a new way to solve the problems of low flash point, and high potential safety hazard during transportation and storage. The present disclosure has a wide range of promotional value.
[06] To solve the above problems, the present disclosure provides a high-flash-point polyurethane-based anticorrosive finishing coat for industrial use, including an A component as a main coating and a B component as a curing agent formulated at a weight ratio of 5:1, where the A component includes: 30-40 parts by weight of a high-solid and low-viscosity thermoplastic hydroxy acrylic resin, 10-20 parts by weight of a stearic acid-modified polyurethane resin, 20-25 parts by weight of a pigment/filler, 0.5-1 parts by weight of a thickener, 1-1.5 parts by weight of a wetting dispersant, 0.1-0.3 parts by weight of a defoamer, 4-8 parts by weight of a co-solvent, 0.1-0.5 parts by weight of an ultraviolet absorber, 5-10 parts by weight of a debenzolization solvent, and 0.1-0.5 parts by weight of a flash point enhancer; and the B component includes: 80-90 parts by weight of an isocyanate curing agent and 10-20 parts by weight of a diluting solvent.
[07] Further, a preparation method of the high-flash-point polyurethane-based anticorrosive finishing coat for industrial use may include the following steps:
[08] step 1, preparation of the A component:
[09] adding 1/2 of the debenzolization solvent and the wetting dispersant into a dispersing kettle, and stirring at low speed for 5-10 minutes; adding 1/3 of the defoamer while stirring; slowly adding 1/2 of the co-solvent, stirring at 900 r/min for 8-10 minutes, adding the pigment/filler and the ultraviolet absorber while stirring, continuing stirring at 800 r/min for -20 minutes, adding the high-solid and low-viscosity thermoplastic hydroxy acrylic resin into a coating mixing kettle, stirring evenly at 300 r/min, and slowly adding an abrasive during stirring; slowly adding 2/3 of the defoamer, the flash point enhancer, 1/2 of the co solvent and 1/2 of the debenzolization solvent at intervals of 3-5 minutes under stirring at 500 r/min, slowly adding the thickener under stirring at 500 r/min for 10-15 minutes; filtering to obtain the A component after the inspection items are qualified;
[10] step 2, preparation of the B component:
[11] mixing and dispersing the water-based isocyanate curing agent and the diluting solvent evenly according to a proportion, and distributing according to a packaging specification to obtain the B component; and
[12] step 3: blending the A component and the B component in a weight ratio of 5:1 to obtain the high-flash-point polyurethane-based anticorrosive finishing coat for industrial use.
[13] Further, the flash point enhancer may include five functional components, which are specifically a component (Cl0-C20 terpenoids and C16-Cl8 fatty soaps) for increasing the intermolecular force, a component (organophosphorus compounds and Cx unsaturated fatty acids) for increasing the boiling point, a component (organic chlorides and organic halogenated hydrocarbons) for increasing the density, a component (C12-C14 anthracenes and C10-C12 naphthalenes) for reducing the saturated vapor pressure, and a component (C4-Cx pyrrolones and C16-C18 fatty soaps) for surface film-forming and flame resistance.
[14] Further, a preparation method of the high-solid and low-viscosity thermoplastic hydroxy acrylic resin may include the following steps: mixing 15 parts by weight of ethyl methacrylate, 10 parts by weight of hydroxyethyl acrylate, 20 parts by weight of hydroxyethyl methacrylate, 20 parts by weight of methyl acrylate, 30 parts by weight of styrene, and 4.5 parts by weight of di-tert-amyl peroxide; heating at 125°C for 6 hours, cooling to 90°C, adding 0.5 parts by weight of hydroquinone, and vacuumizing to remove residual monomers.
[15] The high-flash-point polyurethane-based anticorrosive finishing coat for industrial use of the present disclosure is simple to prepare and convenient to use. The present disclosure increases the flash point through a certain proportion of a flash point enhancer to open up a new way to solve the problems of low flash point, and high potential safety hazard during transportation and storage. The present disclosure has a great potential for broad use.
