Abstract
The invention discloses a surface printing process for a leather paint layer, which comprises the following steps: firstly spraying a thermoplastic primer coat on a base material, baking and curing to form a primer coat layer, then spraying leather paint on the primer coat layer, baking and curing to form a finish coat layer, cleaning the surface of the base material coated with primer coat and finish coat, then printing a printing ink pattern, printing protecting gloss oil on the printing ink pattern, baking and curing to finally form a printed pattern layer. The method is simple, can achieve high product yield, can improve production efficiency, and is convenient for the mass production.
Description
Technical field
The invention belongs to frosting and decorate the field, particularly a kind of technology in the printing of leather dope laminar surface.
Background technology
Leather dope also claims rubberbase paint, handfeel paint or elastomeric paint, is a kind of high resilience polyurethane lacquer.Product behind this paint spraying has soft sense of touch, high resiliency, wear-resisting wiping, resistance to impact and restorability, and its soft feel makes the product of spraying seem comfortable and high-grade, and the outward appearance cloudy surface is transparent, has improved value-added content of product widely.Leather dope is widely used in the surface spraying of products such as various electric plastics, metal, woodenware such as tourism supplies, communication product, audio-visual products, computer peripheral product, stationery, amusement and recreation product, telephone set, MP3, phone housing, decorative plate, game pad, car interior trim, microphone, process gift, beauty treatment equipment, cosmetic brush holder, camera, hair dryer, sports equipment, mouse, LCD TV shell.
Behind the surface spraying leather dope of plastics or metal product, how can be at leather dope laminar surface silk-screen or pad-transfer printing ink, this technology is usually used in products such as phone housing, portable computer external, mouse, USB flash disk, MP3,6PS navigator.
Leather dope laminar surface typography is to spray thermoplasticity priming paint earlier on base material at present, and printing-ink pattern on priming paint, and then sprayed protection lacquer spray leather dope at last.This technique process is loaded down with trivial details, and there is repeatedly the repetitive operation of spraying coating line automatically up and down in product, waste great amount of manpower and material resources, and product yield and production efficiency are low, and cost is higher.
Because the leather dope manufacturer on the market is many, of a great variety, complicated component, leather dope hardness is low, pliability good, its performance is subjected to all multifactor impacts such as producer, raw material, production technology, so the printed patterns performance on the leather dope surface is different, adhesive force, wearability and solvent resistance difference are ubiquitous problems, particularly paper tape is wear-resisting does not reach very high level, the mill run paper tape is wear-resisting generally about 10 times, be difficult to satisfy requirement of client, can't realize the production of mass.
The performance that improves leather dope surface printing printing ink is one of difficult point of needing to be resolved hurrily of printing ink industry.
Summary of the invention
The purpose of this invention is to provide a kind of technology in the printing of leather dope laminar surface, technology has been simplified in this invention, has improved product yield and production efficiency, has improved adhesive force, wearability and the solvent resistance of printing-ink, can realize mass production.
The technical solution adopted for the present invention to solve the technical problems is: a kind of leather dope laminar surface typography, comprise the steps: a), at ten thousand grades of dust free rooms, primer base is stirred, add diluent in proportion and stir, use strainer filtering again, with automatic spraying coating line on the base material to be sprayed, carry out pre-treatment wiping and electrostatic precipitation, spraying thermoplasticity priming paint and baking-curing form prime coat on base material then;
B), at ten thousand grades of dust free rooms, finish paint coating is stirred, add curing agent and diluent in proportion and stir, use strainer filtering, on prime coat, spray leather dope then, baking-curing forms top coat layer;
C), at ten thousand grades of dust free rooms; add printing ink, ink solidification agent and diluent in proportion and stir; the substrate surface cleaning that sprays priming paint and finish paint is clean; printing-ink pattern then; add gloss oil, gloss oil curing agent and diluent more in proportion and stir; printing protection gloss oil on ink logo, baking-curing finally forms printing pattern layer.
Further, described base material can be one or both the composite material among PC, ABS, PMMA, PA, the PPS.
What further, described ink logo printing was adopted is bat printing technology.Described bat printing steel plate etch depth is 20～40 μ m.
Further, first pad-transfer printing ink pattern twice in the described step c), twice of bat printing gloss oil on ink logo then.
The invention has the beneficial effects as follows:
What one, the present invention adopted is bat printing technology, and bat printing steel plate etch depth is 20～40 μ m, and is darker than the etch depth of common bat printing steel plate, increased the thickness of printing pattern layer, obviously improved wearability, and paper tape is wear-resisting higher 5～10 times than common product;
Two, ink lay and gloss oil layer are used in printing, and every layer of twice of bat printing respectively, ink lay provides the adhesive force good with the leather enamelled coating as transition zone on the one hand, one deck of many printings protects the gloss oil layer obviously to improve the wearability and the solvent resistance of printed patterns on ink lay on the other hand, thereby increased the thickness of printing pattern layer, can reach the excellent comprehensive performance;
Three, the printing pattern layer of realizing through this process, adhesive tape pulls no abnormal, and paper tape is wear-resisting brings up to not worn out ground 100 times, and the ethanol-tolerant test is not faded, is not corroded, the wear-resisting test of the denim material that do not see the bottom, the sweat of anti-people test nondiscolouring.
Four, this process is simple, product yield height, and improving productivity is convenient to mass production.
