Problems solved by technology

The BOPET invention mentioned above realizes the matte effect by first preparing or purchasing a large amount of PET matte masterbatch, and does not provide the ratio and preparation of the BOPET film matte masterbatch, and the gloss is less than or equal to 60%, which is far from reaching the standard. And the transmittance is relatively low

preparation example Construction

[0052] The preparation method of BOPET film highly concentrated matte masterbatch comprises the following steps:

[0053] S1 First, prepare the raw materials according to the ratio of each component. The PET raw material is ground into powder in advance, and the particle size is 60 mesh to 70 mesh;

[0054] S2 Mix the raw materials evenly for later use. The order of feeding is to add 1 / 2 of the total amount of PET powder in S1 first, then add silicon dioxide, hyperdispersant, silicone microspheres, matting resin, and the remaining PET powder in sequence, and stir. Set the temperature at 90-120°C, preheat to a certain extent, stir at low speed within 5-10 minutes at the beginning, and the rotation speed is 200-240 rpm, then stir at high speed for 8-13 minutes, and the rotation speed is 700-800 rpm / minute;

[0055] S3 Put the raw materials evenly stirred in S2 into the lower hopper of the extruder to be extruded;

[0056] S4 is extruded through an extruder to obtain a high-co...

Abstract

The invention relates to the technical field of high molecular materials, more specifically, and relates to BOPET film high concentration matt masterbatch and a preparation method thereof. The main points of the technical schemes are as follows: the masterbatch includes, by weight ratio, 50-80 parts of PET, 5-25 parts of silicon dioxide, 1-3 parts of a hyper-dispersant, 3-15 parts of matting resin, 0.1-1 part of an anti-oxidant, and 3-15 parts of silicone microspheres. The masterbatch prepared through the above components and ratio is high in effective concentration, obvious in the cooperativeeffects of several matting components, good in matting effect and low in glossiness of matt BOPET films; and the masterbatch is only applied to the surface layers of the BOPET films, so that the advantage of costs can be obvious.

Description

technical field [0001] The invention relates to the technical field of polymer materials, more specifically, it relates to a BOPET film highly concentrated matte masterbatch and a preparation method. Background technique [0002] BOPET film is a biaxially oriented polyester film. BOPET film has the characteristics of high strength, good rigidity, transparency, and high gloss; it is odorless, tasteless, colorless, non-toxic, and outstanding toughness; its tensile strength is 3 times that of PC film and nylon film, and its impact strength is BOPP 3-5 times that of the film, with excellent wear resistance, folding resistance, pinhole resistance and tear resistance, etc.; heat shrinkage is extremely small, at 120 ° C, only shrinks 1.25% after 15 minutes; has Good antistatic properties. [0003] Chinese invention patent CN107325500A discloses a BOPET color masterbatch and its preparation method, a BOPET color masterbatch, its components are proportioned by mass percentage: low ...
