Description
Technical Field
The invention belongs to the field of chemical coatings, and particularly relates to a two-component automobile baking paint.
Background
With the rapid development of the automotive industry, the demand for automotive coatings has increased accordingly. Baking paint has important market share in the coating field, can be quickly solidified into a film after being sprayed, has higher luster, hardness, water resistance and color stability, and is widely used for decoration, protection and coating of automobiles. Paint film hardness of the baking paint is an important index, and paint film hardness (paint film hardness) is one of important properties representing mechanical strength of a paint film. The physical meaning of which is to be understood as the resistance which the surface of the paint film exhibits against another object of greater hardness which acts on it. Can be determined by measuring the resistance of the coating film to deformation (including deformation due to collision, indentation, or scratching) exhibited when the film is subjected to a certain mass load on a small contact surface.
With the increase of the requirements on the surface hardness of metal substrates such as industrial mechanical equipment, hardware and household appliances, agricultural machinery and the like in the market, the hardness of a paint film of the existing baking paint can not meet the use requirements gradually. The acid curing amino varnish has hard paint film, brightness and good wear resistance. However, the amount of the acidic curing agent added is appropriate, and if the amount is too large, the drying is rapid, but the paint film is easily brittle and cracks are generated even after a long time. If the amount of the acidic catalyst is too small, the drying is slow.
Disclosure of Invention
The invention aims to provide a two-component automobile baking paint to optimize the hardness index of the automobile baking paint.
According to one aspect of the invention, the invention provides a two-component automobile baking paint which comprises the following raw materials in percentage by mass: 15-20% of amino resin, 65-78% of alkyd resin and 0.8-2% of cumene hydroperoxide; the alkyd resin is prepared by polycondensation of polyhydric alcohol, vegetable oil and triazine polybasic acid. The triazine polybasic acid contains a plurality of carboxyl groups, can be used as a monomer for alkyd polycondensation to participate in an ester forming reaction, can play a role of a cross-linking agent, and can remarkably improve the hardness of a paint film formed by baking paint by improving the cross-linking degree of alkyd resin and introducing triazine rings into the molecular structure of the alkyd resin. On the other hand, the triazine ring with ultraviolet absorption activity is introduced into the molecular structure of the alkyd resin, so that the triazine ring is uniformly and stably distributed in the alkyd resin, and the formed alkyd resin has excellent ultraviolet resistance.
Preferably, the amino resin is an aliphatic isocyanate. Because the main chain of the aliphatic isocyanate has no carbon-carbon double bond structure, the color of the paint is not easy to change and the chain is not easy to break under the irradiation of sunlight, and a paint film formed by baking paint containing the aliphatic isocyanate has good aging resistance.
Preferably, the polyol is trimethylolpropane. The trimethylolpropane has three alcoholic hydroxyl groups, has proper reaction activity, and can give consideration to the characteristics of high efficiency and controllability in the process of participating in the alcohol acid condensation reaction. On the other hand, the alkyd resin synthesized by trimethylolpropane has better hydrolytic resistance, oxidation resistance stability, alkali resistance and thermal stability, and simultaneously has the characteristics of bright color, strong color retention, heat resistance and quick drying.
Preferably, the vegetable oil comprises at least one of hydrogenated coconut oil, dehydrated castor oil. Compared with common castor oil, the transparency and anti-yellowing capability of the alkyd resin prepared by adopting dehydrated castor oil as a polymerization monomer are obviously improved.
Preferably, the vegetable oil comprises 6-10 parts by weight of hydrogenated coconut oil and 6-10 parts by weight of dehydrated castor oil. The alkyd resin prepared by using the dehydrated castor oil and the hydrogenated coconut oil together as the polymerization monomer has good quick drying property.
Preferably, the triazine polybasic acid has the structural formula
R1 includes a group having the structure
In the triazine polybasic acid with the structure, carboxyl is distributed relatively uniformly, excellent and controllable reaction activity can be shown in alkyd polycondensation reaction, alkyd resin can form a certain net structure, the aging resistance, the weather resistance and the fullness of the alkyd resin are improved, a paint film formed by the alkyd resin is flexible and firm, the adhesive force is good, the friction resistance is high, and meanwhile, the transparency of the paint and the hardness of the paint film are greatly improved due to the introduction of benzene rings. On the other hand, in the triazine polybasic acid, the carboxyl group as the main crosslinking group is not directly linked to the triazine ring, and the possibility that the triazine ring disturbs the network structure of the alkyd resin due to absorption of ultraviolet light is reduced.
Preferably, R2 has the structure
And/or R3 has the structure
In the triazine polybasic acid with the molecular structure, hydroxyl groups on the benzene ring at the ortho-position of the triazine ring form a chelate ring with nitrogen atoms or oxygen atoms, after ultraviolet radiation is absorbed, hydrogen bonds are broken to generate molecular isomerism, molecules emit energy in a harmless heat energy or other energy forms, the molecules recover again, and the network structure of the alkyd resin cannot be damaged. On the other hand, the benzene group is used for substituting the triazine ring, so that the transparency of the alkyd resin is effectively improved.
Preferably, at least one of R21, R22, R23, R24 is hydroxy; at least one of R31, R32, R33, R34 is hydroxy. The triazine polybasic acid with the molecular structure can be prepared by substituting the halogenated triazine with the resorcinol, the ortho position of the resorcinol as the raw material has higher reaction activity, and the probability of grafting the triazine ring on the ortho position of the phenolic hydroxyl group in the substitution reaction can be improved, so that the yield of the target product is improved.
Preferably, the alkyd resin is prepared by the following method under a nitrogen atmosphere according to parts by weight: s1, melting vegetable oil, and uniformly mixing to obtain liquid vegetable oil; s2, adding part of polyol into the liquid vegetable oil, heating to 80-120 ℃, and adding yellow lead and xylene; s3, heating the reaction liquid obtained in the step S2 to 230-235 ℃, and preserving heat for 2-3 hours; s4, cooling the reaction liquid to 150-200 ℃, and adding the residual polyalcohol and triazine polybasic acid; s5, adding hypophosphorous acid and dimethylbenzene into the reaction liquid; s6, maintaining the temperature of the reaction liquid at 150-200 ℃, and preserving the heat for 1 hour; s7, slowly heating the reaction liquid to 220-225 ℃, and preserving heat for 30-60 minutes. The reaction conditions are informed and controlled, so that the crosslinking degree of the alkyd resin is regulated and controlled, and the proportion of the soft segment to the hard segment is regulated, so that the prepared alkyd resin has good application property, and a paint film formed by the alkyd resin can generate good adhesive force to a coating base material and has higher hardness.
Preferably, the acid value of the alkyd resin is 10 to 11 mgKOH/g.
