Embodiment 1

[0016] A high-efficiency adhesive plastic spraying process method with orange lines, comprising the following steps:

[0017] S1. Pretreatment of iron products to be sprayed with plastic: degreasing, rust removal, and acid-base neutralization treatment are performed on the iron products to be sprayed with plastic; the degreasing agent used in the degreasing process in S1 is acetone. After the iron product to be sprayed is processed by the pretreatment process, the amount of oil carried on the workpiece and the residue of the surfactant are reduced, thereby avoiding the shrinkage cavity of the coating.

[0018] S2. Surface pretreatment of the iron products to be sprayed: grinding, scraping putty, and then grinding on the iron products to be sprayed to ensure that the surface of the iron products to be sprayed is smooth and flat; after cleaning, the iron products to be sprayed are put into the Plating in the plating solution for 2h; the plating solution includes a water-soluble ...

Abstract

The invention discloses an efficient attachment plastic spraying process method with orange lines. The efficient attachment plastic spraying process method comprises the following steps of S1, pretreatment of an iron product to be subjected to plastic spraying, wherein the iron product to be subjected to plastic spraying is subjected to oil removal, rust removal and acid-base neutralization treatment; S2, surface pretreatment of the iron product to be subjected to plastic spraying, wherein the iron product to be subjected to plastic spraying is subjected to grinding, puttying and re-grinding treatment, it is guaranteed that the surface of the iron product to be subjected to plastic spraying is smooth and level, the cleaned iron product to be subjected to plastic spraying is integrally put into a plating solution to be plated for 2-4 h, and the plating solution comprises water-soluble nickel salt and a reducing agent; and S3, plastic spraying treatment of the iron product to be subjected to plastic spraying, wherein after passivation treatment, the iron product to be subjected to plastic spraying is firstly heated to 40-50 DEG C, then plastic spraying powder is subjected to electrostatic spraying to the surface of the iron product to be subjected to plastic spraying by 2-4 times, heating and curing are conducted after electrostatic spraying, the heating and curing temperature is 180-230 DEG C, and the heating and curing time is 8-25 min. According to the method, the phenomenon that shrinkage cavities happen to a coating is avoided, the orange-line-shaped coating is automatically presented, and the surface defects of a substrate are better covered.

Description

【Technical field】 [0001] The invention relates to the technical field of plastic spraying processing, in particular to a high-efficiency adhesive plastic spraying process with orange lines. 【Background technique】 [0002] Plastic spraying is a surface treatment method that sprays plastic powder on parts. The plastic powder is charged by high-voltage electrostatic equipment, and under the action of the electric field, the paint is sprayed onto the surface of the workpiece, and the powder is evenly adsorbed on the surface of the workpiece to form a powdery coating; and the powdery coating is leveled after being baked at high temperature After curing, the plastic particles will melt into a layer of dense final protective coating with different effects and firmly adhere to the surface of the workpiece. The paint film presents a flat or matte effect, which can protect the metal parts and is fashionable and beautiful. Plastic spraying technology is mostly used for surface treatme...
