Abstract
The invention discloses a semi-gloss PET (Polyethylene Terephthalate) film for transferring a furniture coating. The semi-gloss PET film consists of the following raw materials in percentage by mass: 11-63 percent of carbon dioxide-containing polyester master batch, 7-54 percent of blank polyester and 30-40 percent of recovered polyester. The semi-gloss PET film for transferring the furniture coating has a simple preparation process and a good flat gloss effect, and is used for transferring a furniture coating.
Description
Technical field
The present invention relates to a kind of inferior light PET film that the furniture coating shifts that is used for.
Background technology
At packaging field, the glossy degree of popular was higher always in the past, the PET film that transparency is higher; In the last few years, along with the raising of scientific and technological level, the development in pluralism of people's esthetic requirement; Inferior light PET film arises at the historic moment, and its dim outward appearance brings the people different noble experience, therefore; What R&D work in this respect was just like a raging fire carries out; Patent 200410016500.0 discloses a kind of polyester film and working method thereof of single-face matt at least, because its structure is three-layer co-extruded structure, technology is comparatively complicated; US6630224 discloses a kind of multi-layer co-extrusion two-way stretching polyester film of single-face matt at least, and the optical characteristics of this film is unique, yet its matt effect is not good, and glossiness is about 50.
Summary of the invention
The purpose of this invention is to provide a kind of inferior light PET film that the furniture coating shifts that is used for.
The technical scheme that the present invention taked is:
A kind of inferior light PET film that is used for the transfer of furniture coating, its raw material by following mass percent is formed: the polyester returns of the silica containing polyester masterbatch of 11-63%, the blank polyester of 7-54%, 30-40%.
Dioxide-containing silica in the described polyester masterbatch is 1-4wt%.
The particle diameter of the silicon-dioxide in the polyester masterbatch is the 3-8 micron.
The invention has the beneficial effects as follows: inferior light PET film production process of the present invention is simple, and matt effect is better, is used for the furniture coating and shifts.
Embodiment
A kind of inferior light PET film that is used for the transfer of furniture coating, its raw material by following mass percent is formed: the polyester returns of the silica containing polyester masterbatch of 11-63%, the blank polyester of 7-54%, 30-40%.
Silica containing polyester masterbatch is to make through following method:
1) with the SiO of 3-8 micron
2Mixing with mass ratio 20:80 with terepthaloyl moietie, and be uniformly dispersed and obtain suspending liquid A, is that the mixed of 1:2 is even with the mass ratio with suspending liquid A and terepthaloyl moietie again, is mixed with suspension-s B:
2) produce PET Resin/Poyester Chips Bottle Grade, first esterification, polycondensation again according to the PTA method; Before polycondensation, add suspension-s B, and known stablizer and polycondensation catalyst in the industry, reaction conditions is: temperature: 280 ℃; Vacuum tightness 20-60Pa, stirring velocity 45rpm, the reaction times was controlled at 2.5-3.5 hour.
The PTA method is the known technology in the industry, and described stablizer and polycondensation catalyst amount ranges also are known.
The amount of suspension-s B, stablizer and the polycondensation catalyst that adds wherein, through material balance, step 2) is so that the mass content of the silicon-dioxide in the final polyester masterbatch is 1-4wt%.
A kind of inferior light PET film that is used for the transfer of furniture coating, its preparation technology may further comprise the steps:
1) with silica containing polyester masterbatch, blank polyester, the mixing of polyester returns, 160-175 ℃ following crystallizing and drying;
2) dry slicedly under 280-285 ℃, melt extrude, melt flows out to through die head on 30-35 ℃ the slab roller and is cooled to sheet;
3) sheet gets into vertical machine drawing, through the preheat roll preheating, after the Infrared Heating, and vertically on the Tg temperature of polyester draws 2.5-3.5 doubly being higher than, cooling;
4) vertical pulling-on piece gets into the cross directional stretch machine, after 90-100 ℃ preheating zone preheating, horizontally draws 2.5-4 doubly, 215-235 ℃ of following heat setting type, rolling after cooling.
