Embodiment 1

[0039] The manufacture method of the antibacterial flame-retardant ABS plastic of the present invention comprises the following main steps:

[0040] 1) Air-dry the SAN resin at 100-120°C for 4-6 hours;

[0041] 2) Prepare materials according to the formula quantity, add the dried SAN resin, composite environmental protection flame retardant, toughening agent, composite antibacterial agent, anti-scratch agent, antioxidant and compatibilizer into the mixer in sequence, and turn it at 300-500 rpm Stir at a high speed of 100-200 rpm for 3-5 minutes, then add ABS high-gloss masterbatch, and stir at a low speed of 100-200 rpm for 1-3 minutes to obtain a preliminary mixture;

[0042] 3) Add the preliminary mixture into an extruder, melt, extrude, granulate, water-cool, air-dry, pelletize, and dry.

[0043] In addition, the processing conditions of the extruder are as follows:

[0044] Temperature: Zone 1 160-180℃, Zone 2 170-190℃, Zone 3 200-220℃, Zone 4 200-220℃, Zone 5 190-220℃, ...

Embodiment 2-7

[0047] An antibacterial and flame-retardant ABS plastic is manufactured by the method of Example 1 from the following raw materials in parts by weight: 100 parts of SAN resin, 5-30 parts of composite environmental protection flame retardant, 18 parts of toughening agent, 1.9 parts of composite Type antibacterial agent, 3.4 parts of ABS high-gloss masterbatch, 2.5 parts of anti-scratch agent, 0.5 part of antioxidant and 3 parts of compatibilizer, as shown in Table 1.

[0048] Among them, the composite environment-friendly flame retardant consists of the following components by weight: 15 parts of dimethyl trimethylsilyl phosphonate, 38 parts of melamine cyanurate, 16 parts of zinc borate, and 50 parts of magnesium hydroxide.

[0049] The toughening agent is composed of the following components by weight: 1 part of methyl methacrylate-acrylic acid copolymer (ACR), 1 part of methyl methacrylate-butadiene-styrene terpolymer (MBS). Methyl methacrylate-butadiene-styrene terpolymer (MB...

Embodiment 8-13

[0062] An antibacterial and flame-retardant ABS plastic is manufactured according to the method of Example 1 from the following raw materials in parts by weight: 100 parts of SAN resin, 15 parts of composite environmental protection flame retardant, 18 parts of toughening agent, 0.1-3.0 parts of composite Type antibacterial agent, 3.4 parts of ABS high-gloss masterbatch, 2.5 parts of anti-scratch agent, 0.5 parts of antioxidant and 3 parts of compatibilizer, as shown in Table 3.

[0063] Among them, the components of composite environmental protection flame retardant, toughening agent, composite antibacterial agent, anti-scratch agent, antioxidant, ABS high-gloss masterbatch and compatibilizer are the same as those in Examples 2-7.

Abstract

The invention relates to the technical field of polymer modification and provides antibacterial flame-retardant ABS plastic and a preparation method thereof. The antibacterial flame-retardant ABS plastic is prepared from 100 parts by weight of SAN resin, 5-30 parts by weight of a composite eco-friendly fire retardant, 5-20 parts by weight of a flexibilizer, 0.1-3 parts by weight of a compound antiseptic, 0.2-7 parts by weight of a ABS specular master batch, 0.1-5 parts by weight of a scratch resistance agent, 0.1-1 part by weight an anti-oxidant and 2-4 parts by weight of a compatilizer. The preparation method comprises 1, drying the SAN resin, 2, orderly adding the above raw materials into a stirrer, carrying out high-speed stirring, then adding the ABS specular master batch into the mixture, and carrying out low-speed stirring to obtain a preliminary mixture, and 3, adding the preliminary mixture into an extruder and carrying out treatment. The antibacterial flame-retardant ABS plastic has effects of greatly inhibiting bacteria, killing bacteria and preventing mildew, has good flame retardation functions, and has physical properties such as high glossiness, strong scratch resistance, high toughness and high strength.

Description

technical field [0001] The invention relates to the technical field of polymer material modification, in particular to an antibacterial and flame-retardant ABS plastic and a manufacturing method thereof. Background technique [0002] ABS is an acrylonitrile-styrene-butadiene copolymer. It is a light yellow granular or powdery opaque resin. It is non-toxic, odorless, light in weight, has excellent impact resistance, good low temperature performance and chemical resistance, and Good dimensional stability, high surface gloss, easy to color and spray. ABS resin is mainly used in electrical and electronic products such as automobiles, refrigerators, televisions, telephones, office machinery, and small household appliances. [0003] In recent years, the demand for antibacterial household appliances has been increasing, and the country's vigorous advocacy of circular economy and resource reuse has greatly stimulated the development of antibacterial and green environmental protecti...
