Embodiment 1

[0061] Provide a kind of colored matte flame retardant polyester film, comprise core layer, the both sides of described core layer (A layer) are provided with matte layer (B layer) respectively; Described core layer contains phosphorus flame retardant, so The matte layer contains BaSO 4 particles.

[0062] The method for preparing above-mentioned colored matte flame-retardant polyester film, comprises the steps:

[0063] (1) Add transparent optical grade PET slices into a pulverizer to grind polyester powder with a particle size of 0.4 μm to 0.5 μm, and then mix PET powder, flame retardant powder, green pigment powder, dispersant, and antioxidant according to Mass fractions of 62%, 25%, 10%, 2.5%, and 0.5% were added to the agitator, stirred at a high speed of 3000r / min at room temperature for 8 minutes, then reduced to 180r / min and stirred for 4 minutes, and finally the mixed raw materials were placed in the Melt extrusion and granulation under the temperature of 275-285 ℃ ...

Embodiment 2

[0071] For the colored matte flame-retardant polyester film provided in Example 1, the difference between this embodiment and Example 1 is that polyester powder, flame-retardant powder, green pigment powder, dispersant, and antioxidant in the green flame-retardant masterbatch The mass fractions are 57%, 25%, 13%, 4.9%, 0.1%, respectively.

Embodiment 3

[0073] For the colored matte flame-retardant polyester film provided in Example 1, the difference between this embodiment and Example 1 is that the flame-retardant masterbatch is a purple flame-retardant masterbatch, and the polyester powder and flame-retardant in the purple flame-retardant masterbatch The mass fractions of powder, purple pigment powder, dispersant, and antioxidant are 52%, 35%, 10%, 2.5%, and 0.5%, respectively.

Abstract

The invention belongs to the field of films, and particularly relates to a colored matte flame-retardant polyester film and a preparation method thereof. The invention provides the colored matte flame-retardant polyester film and the preparation method thereof in order to overcome the defects that an existing monofunctional BOPET base film is poor in flame retardance, single in color and free of matte degree. The colored matte flame-retardant polyester film comprises a core layer, and matte layers are arranged on the two sides of the core layer respectively, wherein the core layer comprises aflame retardant, and the matte layer comprises BaSO4 particles. The flame-retardant polyester film has excellent flame-retardant performance and also has color and matte effects. The flame-retardant polyester film can be used for packaging and electronic and electric appliance industries.

Description

technical field [0001] The invention belongs to the field of films, and in particular relates to a colored matte flame-retardant polyester film and a preparation method thereof. Background technique [0002] PET material has excellent physical and chemical properties, and is the most widely used thermoplastic linear saturated polyester in the polyester film industry, and is widely used in packaging and electronic and electrical industries. With the continuous improvement of industry application requirements, single-functional BOPET (biaxially oriented polyethylene terephthalate) base films can no longer meet the needs of higher applications, such as food and cosmetic packaging requirements that are colored and have a certain The matte degree makes the appearance more beautiful, and the insulating release film requires that the use area be distinguished by color when used, and it must also have a flame retardant function. Contents of the invention [0003] In order to solv...
