Description

Technical Field

[0001] The invention belongs to the field of coatings, and in particular relates to a high-flash point alkyd coating and a preparation method thereof. Background Art

[0002] Alkyd paint has a long history. Its overall performance is average compared to the current mainstream polyurethane paints. However, alkyd paint is cost-effective, easy to construct, and has low requirements on the construction environment. It is fully capable of meeting the requirements for decorative and protective applications in China, and is still widely used in the domestic market.

[0003] However, traditional alkyd paints have a relatively low flash point and are classified as hazardous chemicals. As the country's requirements for the management of hazardous chemicals increase, the corresponding production, storage, and transportation conditions have also become more stringent. Against this background, high-flash-point alkyd paints came into being.

[0004] Compared with traditional alkyd paints, due to the use of high flash point solvents, the solvent evaporates slowly, the physical drying part is affected, which in turn leads to certain impacts on some properties such as drying, recoatability, hardness, etc. From the existing public literature, some of its properties such as hardness and recoatability are not mentioned or do not meet the national standard GB / T25251-2010 alkyd resin paint recommended by conventional alkyd paints; in terms of anti-skinning, most of the literature uses the method of skinning agent, and the actual anti-skinning performance is glossed over.

[0005] High-flash-point alkyd paints use high-flash-point solvents that meet the requirements of national laws and regulations, which will lead to slow drying overall and affect some performance; although some manufacturers use some illegal solvents, such as dichloromethane, although the drying performance meets the requirements, it is an illegal operation. How to develop high-flash-point alkyd paints with basically the same resistance and mechanical properties as conventional low-flash-point alkyd paints under the necessary premise of high flash point, and some properties such as drying, hardness, and recoating can still meet the national recommended standard GB / T 25251-2010 alkyd resin paints, and the limit of harmful substances must meet or exceed the current relevant mandatory standards of the country (such as GB 30981-2020 Limit of harmful substances in industrial protective coatings), while having a good balance between storage stability, anti-skinning and drying, is a huge technical challenge. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a high-flash-point alkyd coating and a preparation method thereof. The high-flash-point alkyd coating of the present invention has performances referring to conventional alkyd coatings, meets the requirements of GB / T 25251-2010 alkyd resin coatings, and the harmful substance limit is strictly implemented in accordance with the harmful substance limit provisions of GB 30981-2020 industrial protective coatings or is better than the standard, and is safe and environmentally friendly; some effects, such as no biting of the base after recoating for 24 hours and excellent storage performance (no skinning after hot storage at 50°C for 30 days), have not been reported or produced in the current public literature and products.

[0036] The second object of the present invention is:

[0037] To provide a preparation method of the high flash point alkyd paint described above, which is characterized in that:

[0038] It includes the following production steps:

[0039] S1. Mix part of high flash point alkyd resin, part of low naphthalene S150 solvent oil and part of D60 solvent oil, disperse evenly at high speed, add organic bentonite, dispersant and defoamer in sequence under medium and low speed stirring, and then disperse evenly at high speed, then add various environmentally friendly pigments and precipitated barium sulfate under medium and low speed stirring, mix evenly and grind into a sand mill to a fineness of ≤20 microns;

[0040] S2. Sequentially add the remaining high flash point alkyd resin, the remaining low naphthalene S150 solvent oil and the remaining D60 solvent oil, 8% cobalt 2-octanoate drier, 12% zirconium 2-octanoate drier, 4% calcium 2-octanoate drier, 4% zinc 2-octanoate drier (needed in some paint systems), anti-skinning agent, DPM solvent (needed in some paint systems), N, N-dimethylethanolamine (needed in some paint systems), and stir evenly at medium and high speed;

[0041] in:

[0042] 1. Drying system: Most color paints can meet the requirements by using a drying system of 8% cobalt 2-octanoate + 12% zirconium 2-octanoate + 5% calcium 2-octanoate. Some, such as carbon black and BH-F5RK permanent red paint systems, need to be combined with 4% zinc 2-octanoate drying agent on this basis;

[0043] 2. Anti-skinning system: In some paints (such as titanium white and lemon yellow, which are not prone to skinning), only methyl ethyl ketone oxime anti-skinning agent is needed to meet the requirements. In some paints (such as carbon black and phthalocyanine green), DPM solvent needs to be added on the basis of anti-skinning agent. In some paints (such as iron red and iron yellow, which are very prone to skinning), the synergistic anti-skinning combination of "methyl ethyl ketone oxime + DPM solvent + N, N-dimethylethanolamine" needs to be used to improve stability.

[0044] S3. After the test performance meets the requirements, filter and package.

[0045] The basic idea and formulation composition of the high flash point alkyd coating and preparation method thereof of the present invention are as follows:

[0046] 1. Resin: Through a large number of experimental screening, special high flash point alkyd resins with performance that meets the requirements are selected. The selected resins can meet the requirements of the national recommended standard GB / T 25251-2010 (alkyd resin coatings) in terms of drying, resistance, mechanical properties, recoating and other properties.

[0047] 2. Pigments and fillers: Pigments that provide paint hue are selected with harmful substance limits that comply with national mandatory standards and have low oil absorption. Fillers are only precipitated barium sulfate with low oil absorption, high gloss and good anti-settling properties. Gradient experiments are used to confirm the optimal addition amount in different color paint systems under the premise of high gloss.

[0048] The pigments and fillers selected in the present invention strictly control the limits of harmful substances such as heavy metals to meet the national standard requirements, and the addition amounts are confirmed on the premise of high gloss.

[0049] 3. In terms of solvent formulation: The solvents selected in the present invention are required to have a high flash point and low odor for environmental protection. On these two premises, different solvent powers are combined to balance viscosity, recoatability, and storage stability. In some colored paints, high-flash-point hydroxyl-containing solvents are used to improve anti-settling and anti-skinning properties, and their ratios are confirmed through experiments. Most of the relevant patents only provide general descriptions about solvent selection without specific ratios.

[0050] 4. The selection of driers is based on screening existing driers and conducting a large number of experiments. It is designed separately according to the pigments used in different colored paints to obtain the best and most synergistic combination in the present invention. On the premise of meeting dryness and recoatability, the balance among properties such as gloss, distinctness of image, and dryness loss after storage is ensured to the greatest extent, rather than the general descriptions in existing published literature.

[0051] 5. In terms of anti-skinning property, in the colored paint system, some colored paints use anti-skinning agents to meet the anti-skinning requirements. For some colored paint systems prone to skinning, the combination of "anti-skinning agent + alcohol solvent + DMEA" is used to improve anti-skinning performance, and there is no relevant literature report at present.

[0052] Among them:

[0053] Resin: As the basis, it provides the main basic properties. The resin selected in the present invention has a flash point greater than 60 °C, and its dryness and recoatability meet the relevant standards.

[0054] Selection and addition amount of pigments and fillers: They affect gloss, recoatability, and dryness loss. Generally, the more pigments and fillers there are, the better the recoatability, but the gloss decreases significantly. The best addition amount needs to be confirmed on the premise of ensuring gloss. Different pigments require different combinations of driers and anti-skinning agents.

[0055] In terms of solvents: The stronger the dissolving power, the lower the viscosity, the better the storage stability, and the relatively better workability, but the recoatability deteriorates significantly. The weaker the solvent, the better the recoatability, but other aspects decline. A balance needs to be found.

[0056] In terms of driers: Fine-tuning combinations according to each color are required to achieve the best effect. For example, for inorganic titanium white, the dryness loss after storage is small, and the corresponding cobalt and zircon driers can be appropriately reduced, while maintaining a certain amount of calcium drier, which can not only provide good gloss but also maintain good recoatability.

[0057] Organic pigments such as black lose a lot of drying properties after storage, but adding too much drier affects the vividness and gloss, and adding too little makes the recoatability impossible. You can control the dosage of cobalt drier (surface drying), increase the dosage of zirconium drier (actual drying), and compound calcium drier (drying properties after storage) with zinc drier (open time).

[0058] In the traditional low-flash alkyd system, because of its fast drying and good recoatability, the selection of solvents and driers does not need to be too detailed. In most of the public literature related to traditional low-flash alkyd coatings, these two aspects are mostly general.

[0059] In terms of anti-skinning property: adding anti-skinning agent methyl ethyl ketone oxime to some paints can solve the problem, and even if a large amount of anti-skinning agent is added to some paint systems, the anti-skinning property can be improved by greatly reducing the drying agent (under the premise of meeting the minimum drying requirement). The addition of high flash point alcohol solvents and DEMA (N,N-dimethylethanolamine) has a significant improvement. The combination of the two and the anti-skinning agent synergistically act in the iron yellow system that is relatively prone to skinning at 50°C for 30 days. During this period, the lid was opened three times without skinning. It was then extended to some paint systems, which significantly improved the storage stability.

[0060] Among them, methyl ethyl ketone oxime is used as a common anti-scaling principle. The main principles are as follows: 1. Capture free radicals, be oxidized itself, and prevent the reaction from proceeding; 2. Strong solvent; 3. Complex with drying agent.

[0061] The role of alcohol solvents is speculated to be that they act as co-solvents to improve overall solubility and wettability. Their anti-skinning effect slightly improves overall skinning. N,N-dimethylethanolamine is widely used as a neutralizer in water-based alkyd coatings to improve resin water solubility, increase pH value and improve anti-flash rust effect, etc. However, it is rarely used in oil-based alkyd coatings and its anti-skinning effect has not been reported. It is speculated that its principle is more complicated:

[0062] 1. It will react chemically with the hydroxyl group of alkyd resin, indirectly improving the anti-skinning property;

[0063] 2. It may combine with the acidic drier to slow down the release of the drier, and the partial volatilization from the paint film after coating does not affect the drying performance. In actual tests, N,N-dimethylethanolamine not only slows down the skinning, but also slightly promotes the drying effect.

[0064] The synergistic effect of the combination of "methyl ethyl ketone oxime anti-skinning agent + alcohol solvent + N,N-dimethylethanolamine" greatly improves the anti-skinning property of some paint systems. There are no related literature and patent reports. Its effects are described in the following table:

[0065]

[0066] According to the experimental results, in some paint systems that are prone to skinning during storage, simply increasing the amount of methyl ethyl ketone oxime anti-skinning agent cannot improve the anti-skinning performance, while adding a small amount of alcohol solvent on this basis can achieve certain improvements. The combination of "methyl ethyl ketone oxime anti-skinning agent + alcohol solvent + N,N-dimethylethanolamine" can greatly enhance the anti-skinning performance and thus improve storage stability.

[0067] The present invention obtains a high-flash point alkyd coating with excellent performance through the overall scientific design of the formula, the combination of local innovations (such as the combination ratio of some solvents and driers, the solution for anti-skinning in some paint systems), the overall scientific ratio, and the synergistic effect. The flash point is greater than 60°C, and it belongs to the category of non-hazardous chemicals, and can be stored and transported as general chemicals. High gloss, excellent surface effect, mechanical properties, resistance, and dryness all meet the requirements of the traditional alkyd coating recommended standard GB / T25251-2010 alkyd resin coating. It has excellent storage properties (no skinning after 30 days of hot storage at 50°C), which solves the problem of high-flash point alkyd coating biting the bottom after 24 hours of re-coating; at the same time, the limit of harmful substances meets the requirements of the limit of harmful substances in GB 30981-2020 industrial protective coatings.
