Abstract
The invention discloses a spraying curing technology for the plastic part surface. The technology comprises the following steps of polishing, degreasing, electrostatic dust collection, component priming paint spraying, leveling, drying, light polishing, electrostatic dust collection, finishing varnish spraying, curing, standing, checking and packaging. The curing temperature ranges from 70 DEG C to 75 DEG C. Through the technology, the curing hardness of the plastic body surface is higher, and durability is enhanced.
Description
Technical field
The present invention relates to a kind of plastic part surface spraying curing process。
Background technology
Though it is known that working of plastics is before the forming through coloring treatment, but its decorative effect is by the impact of resin intrinsic colour, has certain limitation, generally requires and carry out process of spraying paint。Plastic spraying refers to and adopts suitable coating, through overcompression air by manually or automatically flush coater, carries out a kind of technique covered with paint, lacquer, colour wash, etc. at frosting。Prior art lacks a kind of curing process that plastic part surface solidification can be made good。
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that the plastic part surface spraying curing process that a kind of solidification effect is good。
For achieving the above object, the technical scheme is that and provide a kind of plastic part surface spraying curing process, comprise the following steps:
Polishing, defat, electrostatic precipitation, spray divide priming paint, levelling, drying, tip-tap mill, electrostatic precipitation, spray finishing varnish, solidification, standing, inspection, packaging；Solidification temperature is: 70 DEG C～75 DEG C。Technique described in the application of the invention makes plastic body surface cure hardness higher, and ruggedness strengthens。
As preferably, hardening time is 50 ~ 80min, and keeping temperature is 72 DEG C。Such design is the further optimization to scheme。
As preferably, keeping temperature to be 72 DEG C and be placed on more than room temperature 48h for 60min。Such design is the further optimization to scheme。
Advantages of the present invention and having the beneficial effects that: the technique described in the application of the invention makes plastic body surface cure hardness higher, ruggedness strengthens。
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described。Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this。
Embodiment 1:
A kind of plastic part surface spraying curing process, polishing, defat, electrostatic precipitation, spray divide priming paint, levelling, drying, tip-tap mill, electrostatic precipitation, spray finishing varnish, solidification, standing, inspection, packaging；Solidification temperature is: 70 DEG C～75 DEG C。Because refrigerator door adopts ABS material, high temperature
Under yielding。Through long-term it was verified that under 70 DEG C～75 DEG C conditions of cure, after when placing one section, hardness is significantly increased, and is unlikely to cause door body to deform。
Embodiment 2:
On the basis of embodiment 1, the present invention preferably technical scheme also includes, and hardening time is 50 ~ 80min, and keeping temperature is 72 DEG C。
Embodiment 3:
On the basis of embodiment 2, the present invention preferably technical scheme also includes, and keeps temperature to be 72 DEG C and is placed on more than room temperature 48h for 60min。
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as the protection domain of invention。
Claims (3)
1. a plastic part surface spraying curing process, it is characterised in that: comprise the following steps:
Polishing, defat, electrostatic precipitation, spray divide priming paint, levelling, drying, tip-tap mill, electrostatic precipitation, spray finishing varnish, solidification, standing, inspection, packaging；Solidification temperature is: 70 DEG C～75 DEG C。
