Abstract
The invention discloses a method for eliminating fat edges of high-brightness UV curing paint edges. The method comprises the following steps: firstly determining construction process parameters of a UV curing paint; carrying out construction and acquiring paint stacking shape data of the fat edge of a product; compensating the shape through mould machining; performing injection molding of a production base material; and carrying out spraying and UV curing to obtain the product, the fat edge of which is eliminated. By adopting the method disclosed in the invention, the moulds do not need welding in the development process, so that the cost during the mould development can be reduced. According to the method, the edges of the products are free of fat edge phenomenon, the surfaces of the edges of the products are free of particles, wrinkles and zooming, and the percent of pass of the products can be improved to 85-90%.
Description
Technical field
The present invention relates to a kind of paint staining, particularly relate to the elimination of a kind of high light UV solidification paint edge fat edges
Method.
Background technology
In the car, there are substantial amounts of inner veneer or coverplate parts, such as instrument face plate, gear-lever cover plate, navigator pair
Plates etc., are to be molded by plastic basis material.In order to increase appearance, generally in the surface-coated one of cover plate base material
Floor height light paints.And the surface of automobile cover plate part is a kind of high contact surface, automobile industry standard requires that it has
There is high-wearing feature.In order to improve its wearability, usually require that and highlighted paint is carried out UV cured, to improve
Cover plate or the visual effect of panel and class.The high cover plate of light UV solidification paint or the part of panel have following spy
Property:
1. fat edges: paint itself belongs to liquid material, is sprayed on the molding through overcuring behind the surface of panel or cover plate.
Paint is in heat cure or UV solidification process, because of the surface tension principle of liquid, on panel or the limit of coverplate parts
Can produce fat edges phenomenon at edge, as it is shown in figure 1, shown in figure, 1 is skin of paint, 2 is plastic basis material.
2. defect is amplified: high light paint belongs to wet look material, similar minute surface, plays the presentation defect of part and puts
Big effect；
3. qualification rate is low: the part manufacture that high light UV solidification is sprayed paint needs high level dustfree environment, at part
The tiny granule of surface attachment be bad, qualification rate is only 62%.
Summary of the invention
The purpose of the present invention, it is simply that for the problem overcoming above-mentioned prior art to exist, it is provided that a kind of high light UV
The removing method of solidification paint edge fat edges.
In order to achieve the above object, present invention employs techniques below scheme: limit is painted in a kind of high light UV solidification
The removing method of edge fat edges, comprises the following steps:
One, paint proportioning
According to the different requirements of product base material, the kind of selected UV solidification paint and model, formulate paint proportioning,
Proportioning between the host, diluent and the firming agent that i.e. paint；
Two, lacquer spraying technique debugging
According to the different requirements of product base material, formulate lacquer spraying technique, and use this technique to carry out production of spraying paint；
Three, compensating parameter is obtained
According to the lacquer spraying technique formulated, product is initialized spraying, after sizing, carry out section cutting, obtain product surface
The fat edges shape of paint, obtains corresponding iron supplement data according to fat edges shape；
Four, the iron supplement of mould
According to the technology establishment iron supplement profiling of customization, then mend in the respective surfaces edge of mould according to iron supplement data
Ferrum, to reach to prestore after spraying paint paint thickness；And the respective surfaces of mould is polished minute surface；
Five, plastic basis material trial-production
According to the material of product base material, debug and form Shooting Technique；
Six, spraying application
According to the Shooting Technique formed, product base material is carried out dedusting, electrostatic precipitation and spraying application；Obtain Gao Guang
Bright UV solidifies painting；Whether detection paint edge has fat edges phenomenon, optimizes technique or mould if desired, directly
To producing the product eliminating fat edges.
In described paint proportioning, host: diluent: firming agent=3.4:1-1.2:1.
Described lacquer spraying technique includes the number of plies of paint application, time of spraying paint, flow time and painting thickness.
Described product base material is selected from ABS or ABS/PC.
The present invention compared with prior art, has the following advantages and feature:
1, mould need not welding on stream；
The cost occurred when mould development 2, can be reduced；
3, mould integraty, does not has the air-tightness problem that welding causes；
4, product edge is without fat edges phenomenon；
5, at product edge surface without granule, gauffer, reprint books in a reduce format etc. bad；
3, the qualification rate of product improves up to 85-90%.
Accompanying drawing explanation
Fig. 1 is the fat edges phenomenon schematic diagram of prior art products；
Fig. 2 is that the method for the present invention obtains fat edges shape in the process of implementation；
Fig. 3 is the method for present invention shape after eliminating fat edges.
Detailed description of the invention
The removing method of height light UV of the present invention solidification paint edge fat edges, mainly according to structure and the mould of product
The injection molding process of tool and the technique of spraying, coordinate modulation process to reach to eliminate the mesh of high light paint fat edges edge
's.Below by FAW-Volkswagen automobile Bora NF gearshift panel eliminate as a example by highlighted paint fat edges edge brief description this
Bright process.
First determine that Bora NF gearshift panel uses ABS material, take ABS plate, be processed into gearshift cover plate
Structure.Guaranteeing edge and the fineness on panel construction surface, general fineness reaches Ra0.8.
Next determine gearshift panel carry out the paint kind constructed: Mei Kaiweiqi UV solidification paint (host:
757-12；Firming agent: 605-18；Diluent: 901-70；), solidify light intensity according to UV, according to regulation
Proportions UV solidifies paint.Then according to the construction technology determined, gearshift panel sprays.Through spraying
Series of processes, produces the high light paint gearshift panel sprayed.
In different edge cuts, take cross sectional plane figure, analyze the binding curve determining material with paint, as taken
Bora NF shifts gears panel material, and the binding curve of one of them region and paint is as in figure 2 it is shown, wherein 2-1
It is the thickness shape of standard after spraying, and 2-2 is because of the shape of high light paint edge fat edges after spraying.
According to 2-2 fat edges shape, with material edge line for axle to fertile edge line ray height to weighing up medial border line, as
Shown in Fig. 3, wherein, region 3-1 is the thickness shape of standard after spraying, and region 3-2 is symmetrical edge line out
Shape, for corner transition edge line, uses the ray height fairing of 3-1 spray-coating surface edge linear distance material centrage
Degree edge line, obtains region 3-2 parameter.This region is compensatory zone.
Compensatory zone shows as die iron supplement in mould is processed.Design parameter in die iron supplement is according to general mould
Tool design parameter performs, including the shrinkage factor of material.Complete the processing of mould.
Mould carries out injection trial-production after completing, adjust parameter according to injection testing and measuring technology, is molded by Bora NF gearshift
The molding material of panel.
According to the spraying coating process spraying reserved in advance, draw satisfactory gearshift panel part.
Inner veneer in the present invention and the material material of coverplate parts, the model specification of paint, the core material of mould
The parameters such as material, the moulding process being molded are debugged the most at work and are obtained.
