Abstract
The invention relates to a production method of a decorative plate, in particular to a production method of a decorative plate with abrasion-resistant surface. According to the technical proposal provided by the invention, the production method of the decorative plate with abrasion-resistant surface and deformed edge comprises the following steps: a. material cutting: thin films which are high-temperature resistant and transparent are chosen for carrying out cutting; b. pre-drying: PC thin films or PET films are dried in a drying oven; c. silk-screen printing: characters or/and patterns are printed on the thin films by utilizing silk-screen printing: d. drying: the thin films after carrying out silk-screen printing is sent into a drying channel for being dried; f. injection molding, the thin films which are dried by two times are arranged in a forming mold of an injection molding machine; g. film unloading; the finished products are taken out from the mold cavity, and chip removing, correction, inspection and warehouse entry are carried out. The method can effectively improve the water-proofing and mist-proofing effect of the surface of the decorative plate.
Description
Technical field
The present invention relates to a kind of production method of decorative panel, specifically a kind of production method of decorative plate of abrasion-resistant surface.
Background technology
Decorative panel be widely used in household electrical appliances as: on washing machine, refrigerator, air-conditioning, television set, phone housing and all kinds of instrument face plate.The kind of decorative panel is many, and non metallic decorative plate relatively more commonly used at present mainly contains PC (decoration panel), PET (decoration panel), IMD products such as (in-mould injection spares).Said PET is the abbreviation of polyethylene terephthalate, is milky or polymer light yellow, highly crystalline, and surface smoothing is glossy.In wider temperature range, have excellent physical and mechanical properties, long-term serviceability temperature can reach 120 ℃, and electrical insulating property is good; Even under the high temperature high frequency, its electrical property is still better, but corona resistance is relatively poor; Creep resistance, fatigue durability, rub resistance, dimensional stability are all fine.Said PC is the abbreviation of Polycarbonate, and Chinese name is a Merlon, and PC is a kind of water white indefiniteness thermoplastic.The defective of traditional decorative panel is that the surface is not wear-resisting, in use for some time, will be worn, and, the corner angle of this decorative panel be sharp keen, scratch human body easily.
Summary of the invention
The objective of the invention is to design and produce the production method of decorative plate that a kind of abrasion-resistant surface and corner angle are lopsided shape, to reach the waterproof of improving the decorative panel surface, effect such as antifog.
According to technical scheme provided by the invention, the production method of decorative plate that said abrasion-resistant surface and corner angle are lopsided shape comprises the steps:
A, open material: selecting for use can be high temperature resistant more than 140～150 ℃, and clear films is opened material on cutting machine; Said film is PC film or PET film;
B, prebake conditions: in baking oven, said PC film or PET film are toasted, said film is collected in advance contracted, in order to avoid film produces distortion in next procedure, baking temperature is 95～110 ℃;
C, in serigraphy: on film, utilize serigraphy to print literal or/and pattern;
D, baking: the film that will pass through after the serigraphy is sent into baking in the drying tunnel, 85～95 ℃ of drying tunnel temperatures, 5～8 minutes time;
E, baking once more: the film that will toast is sent baking in the baking oven, 90 ℃～95 ℃ of oven temperatures, 1 hour time again to;
F, injection mo(u)lding will be put into the shaping mould of injection machine through the film after the baking once more, carry out injection moulding then; Injection pressure is 100～105 MPas, and the retention time is 40～60 seconds; Form finished product;
G, unload film: from die cavity, take out finished product, carry out deburring, correction, check, warehouse-in.
After prebake conditions, carry out plated film before the serigraphy: on PC film or PET film, utilize the empty sputter embrane method of magnetic metal-coated membrane.
The metal ingredient of described metal film is: aluminium, chromium, stainless steel or nickel.
When injection mo(u)lding, earlier with the shaping mould preheating: preheat temperature is 70～75 ℃; To put into the shaping mould after the preheating through the film after the baking once more then.
Before serigraphy, first preheating printing ink: the printing ink that serigraphy is used is put into the baking oven preheating; Oven temperature is 90～95 ℃.
The corner angle of said finished product partly are arc transition.
Advantage of the present invention is: the present invention is combined in one with screen printing technique and injection molding technology, guarantees that product meets drawing requirement and the surface reaches wear-resistant, is never rubbed, and peels off etc.When serigraphy, adopt high strength, the ink technology that high extensibility and weather resisteant are good makes product prevent that the back side from being scratched and rub resistance, and can keep the distinctness of color for a long time, can reach the size that requires of drawing around the product, the purpose of abrasion-resistant surface.Substituted the traditional processing technology, and the traditional processing technology can't satisfy the requirement of New Times gradually, as: light, thin, short, little consumption electronic products and the strong requirement of environmental consciousness.
Exempt secondary operation program and manpower thereof, man-hour, guarantee the pattern variation, only need a cover injection forming mold, so when material-saving, joint, the joint cost.
The complicated innovative design of mould design carrying out 3D, and utilize the good extensibility line of film, to reach the product complexity appearance design; Thereby guarantee that four edges and corners of product are various deformities, abrasion-resistant surface, waterproof is antifog and do not wrinkle; Flawless has satisfied user's requirement.
The specific embodiment
The present invention includes two big steps:
One, film producing process:
(1) film must be high temperature resistant (more than 150 ℃) and transparent PC film and PET film (hereinafter to be referred as film), carries out opening automatically on material or artificial (semi-automatic) cutting machine;
(2) material heated baking typing (95～110 ℃, 5～10 minutes);
(3) specialty inks must advance 90～95 ℃ in baking oven in advance, 30 minutes (accurate);
(4) plated film (with the empty sputter coating method of magnetic) carries out, and (aluminium, chromium, stainless steel or nickel etc.) are arranged;
(5) serigraphy (change in pattern need be repeated print);
(6) enter 85～95 ℃ of drying tunnels, 5～8 minutes;
(7) advance baking oven again, temperature (90 ℃～95 ℃), 1 hour time;
(8) die-cut.
After punching molding, the manufacturing process of film has just been accomplished, and next can said film be put into the shaping mould of injection machine, carries out injection mo(u)lding.
Two, moulding moulding technology:
(1) will use the mould elder generation preheating (preheat temperature is 70～75 ℃) of 3D innovative design;
(2) injection mo(u)lding (high pressure 100～105 MPas), the retention time is (40～60 seconds);
(3) take out moulding correction burr, whether the inspection product meets drawing requirement, does various tests such as test of hundred lattice and high and low temperature after the formed product;
(4) product inspection;
(5) warehouse entry;
(6) product export.
