Problems solved by technology

Masterbatch coloring has the advantages of good dispersibility, no pollution and convenient use, and overcomes the problems of color points, color difference and production environment pollution that exist in direct coloring with toner. However, PTT masterbatches mostly use PTT resin as a carrier. PTT resin has poor heat resistance, and discoloration will occur after many times of heat history, which hinders the development of PTT masterbatch

Embodiment 1

[0014] An antibacterial and anti-ultraviolet PTT masterbatch, its components are proportioned by mass percentage: PTT resin 33%, MBS 12%, titanium dioxide 20%, silver ion antibacterial zeolite 10%, 2-hydroxy-4-methoxy Benzophenone 5%, nano attapulgite 15%, bismaleimide 3%, calcium stearate 2%.

[0015] Preparation method: Weigh each component according to the weight ratio, and add them respectively to a high-speed mixer with a cylinder temperature of 80°C-120°C and a speed of not less than 3000r / min, stir for 3-15 minutes, and release after mixing evenly. The material is put into a twin-screw extruder, melted and kneaded at a temperature of 180°C to 260°C, extruded and granulated, and then dried and packaged to obtain an antibacterial and anti-ultraviolet PTT masterbatch of the present invention.

Embodiment 2

[0017] An antibacterial and anti-ultraviolet PTT masterbatch, its components are proportioned by mass percentage: PTT resin 38%, MBS 8%, phthalocyanine blue 15%, silver ion antibacterial zeolite 5%, 2-hydroxy-4-n-octyl Oxybenzophenone 4%, nano attapulgite 25%, bismaleimide 2.5%, sodium polyacrylate 2.5%.

[0018] Preparation method: Weigh each component according to the weight ratio, and add them respectively into a high-speed mixer with a barrel temperature of 80°C-120°C and a rotation speed of not less than 3000r / min, stir for 3-15 minutes, and leave after mixing evenly. The material is put into a twin-screw extruder, melted and kneaded at a temperature of 180°C to 260°C, extruded and granulated, and then dried and packaged to obtain an antibacterial and anti-ultraviolet PTT masterbatch of the present invention.

Abstract

The invention discloses an antibacterial ultraviolet protection PTT color master batch and a preparation method therefor. The PTT color master batch comprises the following ingredients, by weight, 15%-50% of PTT resins, 8%-15% of MBS, 15%-30% of pigments, 5%-15% of silver ion antibacterial zeolite, 3%-8% of light stabilizing agents, 5%-25% of nano-attapulgite, 2%-5% of bimaleimide and 0.5%-3% of dispersants. The beneficial effects are that the nano-attapulgite is employed as a functional filling material, good ultraviolet protection, antibacterial and bacteriostatic synergistic effects are achieved, 5%-15% of the color master batch is added in PTT production, good coloring performance, ageing resistance, antibacterial and bacteriostatic performances, heat resistance, light resistance and the like are achieved, the mechanical properties and the processing performance are raised obviously, usage is convenient, the cost is low, the appearance of the product is good, and popularization is easy.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial and anti-ultraviolet PTT color masterbatch and a preparation method thereof. Background technique [0002] Polytrimethylene terephthalate (PTT) is a kind of poly(ethylene terephthalate) (PET) and polybutylene terephthalate obtained by polycondensation of terephthalic acid and 1,3-propanediol. A new type of polyester polymer material after alcohol ester (PBT), which has good tensile and compressive elasticity, abrasion resistance, moisture absorption and curling properties, and soft hand feeling, and its price is much lower than that of spandex filament. Ideal for highly elastic textiles. In recent years, with the rapid development of masterbatch production technology, the development of PTT masterbatch is also very fast. Masterbatch coloring has the advantages of good dispersibility, no pollution and convenient use, and overcomes the problems of color...
