Description
Technical field
The present invention relates to the elimination sides that a kind of paint staining more particularly to a kind of high light UV solidify paint edge fat edges
Method.
Background technique
In the car, there are a large amount of inner veneer or coverplate parts, such as instrument face plate, gear-lever cover plate, navigator subplate,
It is to be molded by plastic basis material.In order to increase appearance, one layer high bright stock paint usually is coated on the surface of cover board substrate.
And the surface of automobile cover plate part is a kind of high contact surface, automobile industry standard requires it with high-wearing feature.In order to improve
Its wearability usually requires that and carries out UV curing process to highlighted paint, to improve the visual effect and class of cover board or panel.It is high
The part of cover board or panel that bright UV solidifies paint has following characteristic:
1. fat edges: paint itself belongs to liquid material, forms after being sprayed on the surface of panel or cover board by solidification.Oil
Paint, because of the surface tension principle of liquid, can generate in heat cure or UV solidification process in the edge of panel or coverplate parts
Fat edges phenomenon, as shown in Figure 1, as shown in the figure, 1 is skin of paint, and 2 be plastic basis material.
2. defect is amplified: high bright stock paint category wet look material, similar mirror surface play amplification to the presentation defect of part and make
With；
3. qualification rate is low: the part manufacturing that height light UV solidifies spray painting needs high level dustfree environment, in the table of part
Face adhere to tiny particle be it is bad, qualification rate is only 62%.
Summary of the invention
The purpose of the present invention provides a kind of high light UV solidification exactly in order to overcome the above-mentioned problems of the prior art
The removing method of paint edge fat edges.
In order to achieve the above object, the invention adopts the following technical scheme: a kind of high light UV solidification paint edge fertilizer
The removing method on side, comprising the following steps:
One, paint proportion
It is required according to the difference of product substrate, selected UV solidifies the type and model of paint, formulates paint proportion, that is, paints
Host agent, the proportion between diluent and curing agent；
Two, lacquer spraying technique is debugged
It is required according to the difference of product substrate, formulates lacquer spraying technique, and spray painting production is carried out using the technique；
Three, compensating parameter is obtained
Product is initialized according to the lacquer spraying technique of formulation and is sprayed, section cutting is carried out after sizing, obtains product surface oil
The fat edges shape of paint obtains corresponding benefit iron data according to fat edges shape；
Four, the benefit iron of mold
Iron profiling is mended according to the technology establishment of customization, is then mended according to benefit iron data in the respective surfaces edge of mold
Iron, with reach spray painting after prestore paint thickness；And mirror surface is polished to the respective surfaces of mold；
Five, plastic basis material is manufactured experimently
According to the material of product substrate, debugs and form Shooting Technique；
Six, spraying application
According to the Shooting Technique of formation, product substrate is dusted, electrostatic precipitation and spraying application；Obtain high light UV
Solidify painting；Whether detection paint edge has fat edges phenomenon, optimizes technique or mold when necessary, until producing elimination fertilizer
The product on side.
In the paint proportion, host agent: diluent: curing agent=3.4:1-1.2:1.
The lacquer spraying technique includes the number of plies, spray painting time, flow time and the painting thickness of paint application.
The product substrate is selected from ABS or ABS/PC.
Compared with prior art, the present invention having the following advantages that and feature:
1, mold does not need to weld in the process of development；
2, the cost occurred when can reduce mould development；
3, mold integraty, air-tightness problem caused by not welding；
4, product edge is without fat edges phenomenon；
5, product edge surface without particle, gauffer, reprint books in a reduce format etc. it is bad；
3, the qualification rate of product is improved up to 85-90%.
Detailed description of the invention
Fig. 1 is the fat edges phenomenon schematic diagram of prior art products；
Fig. 2 is that method of the invention obtains fat edges shape in the process of implementation；
Fig. 3 is the shape of method of the invention after eliminating fat edges.
Specific embodiment
Present invention height light UV solidifies the removing method of paint edge fat edges, mainly according to the structure of product and mold
Injection molding process and the technique of spraying, cooperation modulation process achieve the purpose that eliminate high bright stock paint fat edges edge.Below with
FAW-Volkswagen automobile Bora NF shift panel briefly explains process of the invention for eliminating highlighted paint fat edges edge.
It determines that Bora NF shift panel uses ABS material first, takes ABS plate, be processed into the structure of shift cover board.Really
The finish at edge and panel construction surface is protected, general finish reaches Ra0.8.
Secondly the paint type constructed in shift panel: the UV solidification paint (host agent: 757- of Mei Kaiweiqi is determined
12；Curing agent: 605-18；Diluent: 901-70；), luminous intensity is solidified according to UV, according to the proportions UV solidified oil of regulation
Paint.Then it according to determining construction technology, is sprayed on shift panel.By spraying series of processes, produces and sprayed
High bright stock paint shift gears panel.
It is cut at different edges, takes cross sectional plane figure, analyzed the binding curve for determining material and paint, such as take Bora
The binding curve of NF shift panel material, one of region and paint is as shown in Fig. 2, wherein 2-1 is standard after spraying
Thickness shape, and 2-2 is the shape after spraying because of high bright stock paint edge fat edges.
According to 2-2 fat edges shape, using material edge line as axis to fertile edge line ray height to weighing up inside edge line, such as Fig. 3
It is shown, wherein region 3-1 is the thickness shape of standard after spraying, and region 3-2 is the edge wire shaped symmetrically come out, for corner
Transition edge line obtains region 3-2 ginseng using the excessive edge line of ray height fairing of 3-1 spray-coating surface edge linear distance material center line
Number.This region is compensatory zone.
Compensatory zone shows as cavity plate in mold processing and mends iron.Cavity plate mends the design parameter in iron according to general mold
Design parameter executes, the shrinking percentage including material.Complete the processing of mold.
Injection molding trial-production is carried out after the completion of mold, according to injection molding testing and measuring technology adjusting parameter, is molded by Bora NF shift panel
Molding material.
According to the spraying process spraying set in advance, satisfactory shift panel part is obtained.
The core material of the material material of inner veneer and coverplate parts, the model specification of paint, mold in the present invention,
Debugging obtains the parameters such as the moulding process of injection molding at work.
