- Figure 1 shows the appearance of the particles.
- FIG. 2 is a diagram schematically showing a test material. BEST MODE FOR CARRYING OUT THE INVENTION
- the paint of the present invention is a paint containing 60% by mass or more of a zinc-based alloy powder.
- the powder is aluminum-powder 10 mass 0 /. Not less than 30% by mass, the balance being zinc and unavoidable impurities, and the powder is spherical or elliptical spherical, and the ratio of the maximum diameter to the minimum diameter (maximum diameter Z minimum diameter) Is 1 to 1.5.
- the paint contains 60% by mass or more of zinc-based alloy powder. If it is less than 60% by mass, effects such as color tone and corrosion resistance equivalent to those of a zinc-based alloy cannot be obtained.
- the upper limit of the content of the powder is not particularly specified, but if it exceeds 85% by mass, the resin component becomes too small, and the coating film tends to have defects.
- the powder contains 60% or more of the above powder, other powder particles may be contained.
- metal powders such as Al, Zn, stainless steel, titanium oxide, An oxide powder such as zinc or an extender pigment such as talc or stone powder may be contained.
- the zinc-based alloy powder contains 10% by mass or more and 30% by mass of aluminum and the balance consists of zinc and unavoidable impurities. If the aluminum in the zinc-based alloy powder is less than 10%, the zinc elution rate in the zinc-based alloy powder is high, so that sufficient corrosion resistance to the iron surface cannot be obtained for a long period of time. If it is 30% or more, the electrochemical corrosion potential approaches that of iron, and the effect of protecting the iron surface is weakened, so that redness is likely to occur, and as a result, the corrosion resistance is reduced. It becomes.
- the shape of the zinc-based alloy powder is spherical or elliptical spherical, and the ratio of the maximum diameter to the minimum diameter (maximum diameter / minimum diameter) must be 1 to 1.5. That is, the surface area of the metal powder or the surface area per volume (specific surface area) greatly affects the performance of the coating film.
- the specific surface area should be as small as possible to prevent the elution of metal powder, especially when coating on the alloy. Enhances the adhesion of the coating at the site where it is mounted.
- the shape of the metal powder must be spherical or elliptical.
- the ratio of the maximum diameter to the minimum diameter is specified in 1 to 1.5. When this ratio is 1, the shape is spherical.
- the above provisions stipulate metal powder as a raw material. Therefore, the above rule is applied to the case where particles are agglomerated and bound by absorbing moisture in the air before the particles are actually mixed with the paint, It does not specify the shape of the zinc-based alloy powder in the case where the particles are combined and hardened in the above.
- the method for producing the metal powder of the present invention is not particularly limited, but generally, an atomizing method and a pulverizing method are used.
- a pulverizing method In the atomizing method, spherical or elliptical spherical powder can be easily produced, and in the pulverizing method, the powder shape tends to deviate from spherical or elliptical spherical.
- the atomization method is appropriate in terms of powder form.
- the resin component of the paint of the present invention is not particularly limited, but preferably has excellent water resistance and alkali resistance, and is preferably an epoxy resin, a modified epoxy resin, an acrylic resin, or a urethane resin. , Polyester resin and the like can be applied as appropriate.
- the compounding type of the curing agent a one-component curing type or a two-component curing type can be appropriately applied according to the purpose.
- the curing method room temperature curing, heat curing, UV curing, electron beam curing and the like can be appropriately applied according to each purpose.
- the particle diameter of the ffi-lead alloy powder of the present invention is preferably 35 ⁇ m or less in terms of 90% cumulative particle diameter (d 90 ). That the d 90 of the zinc-based alloy powder less 35micro Paiiota is as a result, the particle diameter larger ones to be less, which means that it is effective in corrosion resistance.
- the 90% cumulative particle size ( d9Q .) Means the particle size equivalent to 90% of the total particles obtained by integrating the particle sizes from small particles based on the particle size distribution measured by the light scattering method. I do. As long as the 90% cumulative particle size (d 9 ) can be obtained by conversion, the light scattering method may also be used.
- the average particle diameter of the powder is more preferably 2 ⁇ or more. If the average particle size is less than 2 ⁇ m, there will be many extremely small particles.In this case, when kneading the paint, the reaction between the particles and the resin component proceeds, and the viscosity of the paint Increases significantly, making painting difficult. As a result, the coating film has many pinholes and defects, resulting in poor corrosion resistance.
- the average particle size at this time is also determined by integrating the particle size with a 50% cumulative distribution based on the particle size distribution measured by the light scattering method. Even when measured by other methods, the cumulative particle diameter may be obtained by conversion, and may be used instead of the light scattering method. If the average particle size is larger than 2 ⁇ m, problems due to large particles scattered in the coating film are likely to occur.
- the zinc-based alloy powder contains magnesium in an amount of more than 0% by mass and less than 1% by mass, or silicon in an amount of 0.1% by mass or more and 3.0% by mass or less. Both are preferably added.
- the composition of the zinc-based alloy powder may be appropriately selected according to the type of the plating layer of the steel material coated with the zinc-based alloy, but in the case of plating containing magnesium in the plating layer, use a metal powder containing magnesium. It is desirable.
- the magnesium component When the magnesium component is contained in the zinc-based alloy powder in an amount of 1% by mass or more, the zinc-based alloy powder is easily eluted in a corrosive environment. The adhesiveness of the coating film significantly deteriorates, and swelling and peeling are likely to occur.
- the addition of silicon is effective in improving the corrosion resistance of the coating film on the steel material, and the effect can be obtained by adding 0.1% by mass or more. Further, the effect is increased by adding more, but the effect of improving the corrosion resistance is weakened by adding more than 3.0% by mass. On the other hand, the production of metal particles becomes difficult, and therefore, practically less than 1.0% by mass is desirable.
