For reaching the purpose of the invention described above, part for motor bicycle of the present invention is characterised in that: after forming the filming of individual layer on casting ingot surface and its machined surface, under the baking temperature of 50 ℃≤T≤80 ℃, carry out force drying as 1 drying operation, then by drying operation is finished, forming thickness is the above signal layer coatings of 10 μ m, described amount of filming by organic solvent is that the acrylic silicon resin coating below the 50 weight % constitutes, in force drying, described coating reaches time of 60% o'clock and is adjusted into below 2 hours by using curing catalysts, make film under the baking temperature of 50 ℃≤T≤80 ℃ reactivity.
In addition, part for motor bicycle of the present invention, it is characterized in that: after forming the filming of individual layer on casting ingot surface and its machined surface, under the baking temperature of 50 ℃≤T≤80 ℃, carry out force drying as 1 secondary response, then by finishing reaction at normal temperatures, forming thickness is the coating of the above individual layer of 20 μ m.
And then, described filming, be that silicon Acrylote resin coating below 50% constitutes by the amount of organic solvent be desirable, in addition, and by using curing catalysts, make under the baking temperature of the 50 ℃≤T≤80 ℃ reactivity of filming reach time of 60% and adjust to below 2 hours, coating be desirable.
In addition, in order to constitute the coloring and coating parts, the pigment that is blended in the coating is that nonpolarity pigment is desirable.
(invention effect)
In the present invention, by baking temperature T being set in 50 ℃≤T≤80 ℃, filming to become the monolayer constructions will that applies 1 time, even be present in the defective of pore as the surface opening of the cast component of coated object etc., the expansion that is comprised in the gas in this defective is also very little, expand or pore thereby on coated surface, do not produce, even perhaps generation is also very little, the decline that can not bring commodity value.Amount with an organic solvent is the acrylic silicon resin coating below 50%, adjust to below 2 hours by using curing catalysts reactivity under the temperature of 50 ℃≤T≤80 ℃ can be reached time of 60%, simultaneously, because its good connecting airtight property and viscosity characteristics, so the formation of filming for the individual layer of 1 coating is desirable.In addition, the organic solvent amount of coating in the past is more than 60%.
Such the present invention takes place and need be coated with 2 times, the coating process that is coated with 3 times application cast component and change into and being coated with 1 time by making in the past for fear of defective products, can omit operation, reduce the use amount and the defective goods incidence of coating.
On this basis, though can obtain sufficient film performance with above the filming of individual layer of 10 μ m in the past, further be more than the 20 μ m by making this, can also improve the film performance when being in unusual condition (collisions of gravelstone and sharp sand etc.).The thickness increase of filming in addition, also has the benefit that is difficult in appearance reveal and improves the commodity performance.
In addition, by setting forced drying temperature, also can reduce consumption electric power than the lowland.The effect that these all bring big cost to reduce.And then, be below 50% by the amount that makes the organic solvent in the coating, the contribution to the reduction carrying capacity of environment when reducing weight of coated paint is also big.
About painted, evenly mix difficult acrylic silicon resin for pigment, adapt to nonpolarity pigment by making, can provide outward appearance good coloring and coating parts with pigment addition same.
