Example Embodiment

[0034] The preparation method of the antibacterial agent includes the following steps:

[0035] (1) Weigh a certain amount of kaolin, deionized water, chitosan, and nitric acid solution, add them to the reaction vessel in turn, stir and react for 10-12h at room temperature to form solution A; kaolin, deionized water, chitosan The mass ratio of nitric acid solution is (60-80): (180-240): (20-30): (28-36).

[0036] (2) Weigh a certain amount of Cu (NO3) 2 Solution, fructose, solution A, add them to the reaction vessel one by one, stir and react for 8-10h in a water bath at 60-80℃ to obtain solution B; Cu(NO3) 2 The mass ratio of solution, fructose, and solution A is (20-30): (30-40): (100-120).

[0037] (3) Filter, wash, dry, and grind the solution B, and pass through a 500-mesh sieve to obtain a copper-loaded kaolin antibacterial agent.

[0038] The flame retardant is Mg(OH) 2 .

[0039] The synergistic flame retardant is a mixture of nano-TiO2 and zinc hydroxystannate, and their mass r...

Example Embodiment

[0045] Example 1

[0046] (1) Weigh 80 parts PET, 2 parts antibacterial agent, 18 parts Mg(OH) 2 , 2 parts of zinc hydroxystannate, 2 parts of nano TiO2, and 0.1 part of Irganox168 are mixed and stirred to obtain a mixture;

[0047] (2) Extruding and granulating the mixture obtained in step (1) to obtain the PET composite material P1.

[0048] The temperature and screw speed of each zone of the twin-screw extruder are respectively: a zone temperature of 240℃, a zone 2 temperature of 280℃, a zone 3 temperature of 280℃, a zone 4 temperature of 280℃, a zone 5 temperature of 280℃, and a zone 6 temperature of 280℃. The head temperature is 280℃, and the screw speed is 200r / min.

Example Embodiment

[0049] Example 2

Abstract

The invention relates to an antibacterial flame-retardant PET composite material and a preparation method thereof. The material consists of the following components in parts by weight: 80 parts-100 parts of PET; 2 parts-6 parts of an antibacterial agent; 18 parts-24 parts of a flame retardant; 4 parts-6 parts of a synergistic flame retardant; and 0.1 parts-0.5 parts of an anti-oxidant; wherein theantibacterial agent is a copper-loaded kaolin antibacterial agent. The technical scheme firstly uses a mixture of nano TiO2 and zinc hydroxystannate as the synergistic flame retardant, which improvesthe flame retardant performance of the PET composite material; The PET composite material prepared by the technical scheme has excellent flame retardant performance and antibacterial property, and makes up for the deficiency of the existing products, and has great popularization value.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to an antibacterial and flame-retardant PET composite material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) has the advantages of light weight, non-toxic, odorless, good chemical stability, insoluble in common solvents at room temperature, and low water absorption. Although the overall performance of PET is excellent, the antibacterial performance and flame retardancy of PS are average, which greatly limits the application range of PET composite materials. [0003] In view of this reason, this technical solution innovatively uses a new type of antibacterial agent to improve the antibacterial performance of PET, and at the same time uses a flame retardant and a synergistic flame retardant to improve the flame retardant performance of PET, and finally prepares a kind of antibacterial performance and antibacterial PET compo...
