Embodiment 1

[0027] The steps of this embodiment are as follows:

[0028] S1. Grind the colorant through a high-speed grinder to reduce the particle size. The colorant used is Pigment Blue 15:3, and the speed of the grinder is set to 6000rpm;

[0029] S2. 5 parts of colorant obtained in S1 are mixed with 70 parts of polyethylene terephthalate (bottle-grade polyester resin), 3 parts of dispersant oleic acid amide, and 10 parts of nanoscale ultraviolet absorber UV-234 in Mix in a high-speed kneader. After mixing evenly, discharge the material and add it to the main feeding port of the twin-screw extruder. At the same time, add the meta-aramid fiber weighed according to the weight ratio 7 parts of fiber are melted and kneaded by twin-screw extruder, the screw speed is then extruded and granulated, and extruded in the twin-screw machine, the speed is set to 100Hz, the feed rate is 15Hz, water-cooled and pelletized, and the temperature of the extruder is as follows As shown in the table:

Embodiment 2

[0035] The steps of this embodiment are as follows:

[0036] S1. Grind the colorant through a high-speed grinder to reduce the particle size. The colorant used is pigment red 48:2, and the speed of the grinder is set to 6000rpm;

[0037] S2. 10 parts of the colorant obtained in S1 are mixed with 80 parts of polyethylene terephthalate (film-grade polyester resin), 1 part of dispersant erucamide, and 15 parts of nanoscale ultraviolet absorber UV-531 in Mix in a high-speed kneader. After mixing evenly, discharge the material and add it to the main feeding port of the twin-screw extruder. At the same time, add the meta-aramid fiber weighed according to the weight ratio 5 parts of fibers are melted and mixed by a twin-screw extruder, and the screw speed is then extruded and granulated. In the twin-screw machine, the speed is set to 105Hz, the feed rate is 15Hz, water-cooled and pelletized, and the temperature of the extruder is the same as Example 1.

Abstract

The invention relates to BOPET (Biaxial oriented Polyethylene Terephthalate) ultraviolet shielding master batch. The BOPET ultraviolet shielding master batch is prepared from the following raw materials in parts by weight: 70 to 90 parts of polyethylene terephthalate, 1 to 5 parts of a dispersant, 5 to 20 parts of a coloring agent, 10 to 20 parts of a nano-grade ultraviolet absorbent and 5 to 10 parts of meta-aramid fibers. According to the BOPET ultraviolet shielding master batch provided by the invention, the coloring agent is ground through a high-speed grinding machine; the aramid fibers are added and the nano-grade ultraviolet absorbent is matched, so that a dispersion effect of the coloring agent and the ultraviolet absorbent is good; meanwhile, the fibers are also dispersed well and have no tangling phenomenon; the filtering performance is good and a BOPET ultraviolet shielding film prepared from the BOPET ultraviolet shielding master batch has a ultraviolet shielding rejection rate reaching 100 percent, and the film haze is less than 2; the master batch is used for producing the BOPET ultraviolet shielding film; a net replacing period is long, and film-forming performance is good. The invention further relates to a preparation method of the BOPET ultraviolet shielding master batch.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a BOPET ultraviolet shielding masterbatch and a manufacturing method thereof. Background technique [0002] PET, namely polyethylene terephthalate, is a polymer with large output and low price. It has excellent properties such as high rigidity, heat resistance and good chemical stability. BOPET is biaxially oriented polyester film, which is widely used. With the improvement of people's living standards, people pay more and more attention to their own health. Ultraviolet rays in sunlight are an inevitable thing that affects people's health. How to effectively reduce the impact of ultraviolet rays on their own health has become a topic today. Among them, due to the problems of appearance and use, the glass of automobiles and high-end houses urgently needs ultraviolet shielding films to protect people and objects inside cars and high-end houses from ultraviolet rays. How...
