Problems solved by technology

[0004] In order to meet the requirements of anti-sticking, too much lubricant is often added, but the general lubricant will significantly affect the surface tension. PET material itself has good printing performance, but the addition of improper slip agent may lead to a decrease in the surface tension of the sheet, while Affect printing performance; anti-blocking agent is easy to agglomerate and poorly dispersed, thus affecting the gloss and transparency of the sheet, so that the optical performance of the sheet cannot meet the index requirements

Embodiment 1

[0029] The weight percent composition of the special anti-adhesive masterbatch for PET sheets is as follows:

[0030]

[0031]

[0032] The production process of Example 1 is as follows: Weigh the raw materials of each component, mix the raw materials of each component through a high-speed mixer at a speed of 80r / min, and then melt and extrude the mixed raw materials through a twin-screw extruder, and dry , cooling, pelletizing and molding;

[0033] Among them, the production temperature of each zone of the twin-screw extruder is shown in Table 2. The melt pressure of the twin-screw extruder is 4.1Mpa, the main engine current is controlled at 45A, the main engine speed is controlled at 325r / min, and the feeding is controlled at 25HZ. The speed is controlled at 550r / min.

Abstract

The invention discloses an anti-sticking masterbatch special for a printable PET (Poly Ethylene Terephthalate) sheet material and a preparation method thereof. The anti-sticking masterbatch is prepared from the following components in parts by weight: 85% to 95% of PET, 2% to 8% of anti-sticking agent, 1% to 4% of compatible modifier, 1% to 4% of lubricant and a proper amount of antioxidant, wherein the adding amount of the antioxidant is based on the adding total amount of all components. The preparation method comprises the following steps: weighing all component materials and evenly mixing so as to form a mixture; carrying out melting extrusion on the mixture by using a melt extrusion; and drying, cooling and cutting into granules for molding. The PET sheet material utilizing the anti-sticking masterbatch has the good anti-sticking performance; the influences to the transparency and the haze of the PET sheet material are minimized; and the subsequent machining and manufacturing process of the sheet material is smooth and fluent, so that the production efficiency is improved, the problems of the appearance quality of the PET sheet material are reduced and the influence to the surface tension of the sheet material is not serious. Thus, the PET sheet material has the good printability for inks.

Description

【Technical field】 [0001] The invention relates to a special anti-adhesive masterbatch for PET sheets and a preparation method thereof, in particular to a special anti-adhesive masterbatch for printable PET sheets and a preparation method thereof, belonging to the technical field of PET sheets. 【Background technique】 [0002] In the production process of PET sheets, when the PET sheets are rolled, or the sheets are stacked together, between the sheets; Adhesion will occur between them, which will affect the subsequent processing and manufacturing of the sheet, and will affect the appearance quality of the sheet. In order to solve this problem, it is necessary to add special anti-adhesion and smooth materials for the sheet. The synergistic effect of the two plays a very important role. Good anti-stick effect. [0003] A certain amount of anti-blocking agent is added to the PET sheet. The added anti-blocking agent is in the state of microsphere particles, forming protrusions o...
