Abstract

The invention provides a digital printing single-side perspective PVC (polyvinyl chloride) black and white film for realizing the technical effect of good shading property and high peel strength. The black and white film comprises a layer of white PVC film and a layer of black PVC film, wherein the thickness of the white PVC film is 0.07-0.08mm, and the thickness of the black PVC film is 0.06-0.07mm. The fabrication method comprises white PVC film unrolling, a surface film roll preheating, black PVC film unrolling, a bottom film roll preheating, press fitting, vat heating and blending, conveying and heating, press fitting, cooling and rolling steps. The black and white film solves the technical problems that the adhesive force is poor when the traditional white PVC film is printed with black printing ink or coated with black rubber products, the black rubber and the printing ink easily fall off, and the shading property and single-side perspective effect are influenced; meanwhile, the fabrication process is more environmentally friendly due to no use of solvent and printing ink.

Description

Digital single plane fluoroscopy PVC black and white film and the manufacture craft thereof printed

Technical field

The present invention is applied to the show and colour of indoor outer advertisement, especially a kind of digital single plane fluoroscopy PVC black and white film and manufacture craft thereof printed.

Background technology

Be used for the body of a motor car glass advertisement, the glass curtain wall advertisement, the digital main material of printing the required usefulness of single plane fluoroscopy product of the production of market showcase advertisement is the PVC film, PVC full name is Polyvinylchlorid, Main Ingredients and Appearance is a polyvinyl chloride, conventional fabrication processes generally adopts flattener to prolong the PVC film of pressing white, simultaneously at the bottom surface of white PVC film printing solvent type black ink of one deck or the black glue of coating one deck, the product of printing-ink is because the printed layers thinner thickness, the poor adhesive force of printing ink and PVC film, black ink peels off easily, the light-proofness and the single plane fluoroscopy effect of product have been destroyed, cause the problem of two sides perspective, and because it is poor to use solvent type printing ink to cause operating production environment, the product environmental-protecting performance is poor; The product that applies black glue is because colloidality is not good, and coat is thinner relatively, also can influence the adhesive force of product, and black glue comes off easily, influences the light-proofness and the result of use of product equally.

Summary of the invention

It is good that the technical problem to be solved in the present invention provides the shading performance, and the number that peel strength is high is printed single plane fluoroscopy PVC black and white film.

The present invention is achieved in that the digital single plane fluoroscopy PVC black and white film of printing, and it is characterized in that comprising one deck white PVC film and one deck black PVC film, and the thickness of described white PVC film is 0.07-0.08mm, and the thickness of described black PVC film is 0.06-0.07mm.

Preparation method of the present invention be adopt white PVC film unreel-facial mask preheat roll-black PVC film unreels-counterdie preheat roll-pressurizing attaching-vat heating fusion-conveying heating-pressing-cooling-rolling finishes.The big volume of white PVC film is along with roll shaft at the uniform velocity goes to the facial mask preheat roll, and the preheat roll temperature is controlled at 150-160 ℃; The big volume of black PVC film is along with roll shaft at the uniform velocity goes to the counterdie preheat roll simultaneously, and the preheat roll temperature is controlled at 145-155 ℃; Then white PVC facial mask and black PVC counterdie are closed in pressurizing attaching place heat posted, make tunica albuginea and black film tightr; The black and white film that applying is finished is carried warm-up mill successively by vat warm-up mill (fusion) subsequently, and the vat heating roller temperature is controlled at 155-165 ℃, carries heating roller temperature to be controlled at 150-160 ℃; In pressing place pressing, finished product thickness is controlled at 0.12-0.15mm; The black and white film that pressing is good through four chill rolls, cools down successively, and what inject in four chill rolls is the recirculated water of cooling under the normal temperature; Rolling is finished.

The invention has the beneficial effects as follows, the present invention is by improving the vanguard technology that traditional handicraft adopts black PVC film and white PVC film heat posted to close, strengthened the peel strength of black film and tunica albuginea, the black film difficult drop-off, solve existing white PVC film process black printing ink or applied black glue product poor adhesive force, black glue, printing ink come off easily, influence the technical barrier of light-proofness and single plane fluoroscopy effect; Because do not use solvent, printing ink, production technology is environmental protection more, meets the demand for development of existing market simultaneously.

So the present invention is that a kind of shading performance is good, the number that peel strength is high is printed single plane fluoroscopy PVC black and white film.
