Embodiment 8

[0040] A preparation method of antibacterial and mildew-proof transparent ABS masterbatch, is characterized in that, comprises the following steps:

[0041] S1. Raw material pretreatment;

[0042] S2. Put the masterbatch raw material into the high-speed mixer according to the weight ratio and stir evenly;

[0043] S3. Control the temperature of each zone of the twin-screw extruder within the range of 160°C-200°C, keep the vacuum degree of the vacuum vent hole of the extruder within the range of -0.1MPa--0.09MPa, and add the mixed raw materials into the twin-screw extruder Melt blending in a screw extruder, extruded into strips, cooled, dried, pelletized, and packaged to complete the preparation of transparent ABS antibacterial and anti-mildew masterbatch.

[0044] In the present invention, the masterbatch is prepared by a method of melt blending.

[0045] Further, in step S1, it includes pre-treating the transparent ABS resin and the antibacterial and antifungal agent respec...

Abstract

The invention belongs to the technical field of high polymer material modification, and provides an antibacterial mildew-proof transparent ABS master batch which comprises the following components in parts by weight: 72-82 parts of transparent ABS resin, 2-8 parts of a first dispersing agent, 15-23 parts of an antibacterial mildew-proof agent, 1.5-3.2 parts of a second dispersing agent, 0.01-1 part of a hindered phenol antioxidant, 0.02-1.3 parts of a phosphite antioxidant and 0-0.1 part of ultramarine pigment powder. According to the invention, through pretreatment of the antibacterial mildew-proof agent, a raw material mixing process and a melt blending process, uniform dispersion of the antibacterial mildew-proof agent in the ABS resin is ensured, so that the antibacterial mildew-proof agent has broad-spectrum and high-efficiency bactericidal performance of an organic antibacterial mildew-proof agent and the characteristics of safety, long-acting effect, temperature resistance and the like of an inorganic antibacterial mildew-proof agent, and simultaneously keeps the transparency of ABS workpieces.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to an antibacterial and antifungal transparent ABS masterbatch and a preparation method thereof. Background technique [0002] The development and utilization of antibacterial plastics is one of the research hotspots in the field of functional plastics. Traditional plastic substrates such as polycaprolactone (PCL), low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP) , Ethylene-vinyl acetate copolymer (EVA), polylactic acid (PLA), acrylonitrile-butadiene-styrene copolymer (ABS) can be modified by adding antibacterial agents. [0003] ABS (acrylonitrile-butadiene-styrene) resin is an important general-purpose synthetic resin. The main body is a blend or terpolymer of acrylonitrile, butadiene and styrene. It is a tough and rigid thermoplastic. plastic. It has a wide range of uses. The automobile industry is often use...
