Problems solved by technology

CN104629300A realizes spray-free PC resin with special aesthetic appearance effect by coating special effect powder with water-based polymer microspheres, and can obtain various aesthetic appearance effects such as metallic texture and glass pearl; CN106084716A describes a high-gloss black appearance effect The spray-free PC / ASA material, but the addition of carbon black masterbatch puts a higher limit on the appearance color of the material, and cannot be applied to other light-color appearance free spray material systems
Based on the current development cases of spray-free PC alloy materials, most of the research and development focuses on the improvement of the surface effect, and it is difficult to take into account other functional improvements such as fingerprint resistance and the resulting antibacterial requirements. The addition of a large amount of additives not only easily leads to a substantial increase in cost, but also tends to cause component interference between additives, which greatly reduces the modification effect

Abstract

The invention relates to a highly antibacterial and anti-fingerprint spraying-free polycarbonate alloy material and a preparation method thereof. The highly antibacterial and anti-fingerprint spraying-free polycarbonate alloy material specifically comprises the following raw materials in parts by weight: 30-70 parts of PC resin, 5-20 parts of ABS resin, 6-20 parts of nano-state functional master batch, 2-6 parts of metal toner and 0.5-3 parts of a dispersing aid. The nano-state functional master batch is prepared from the following components in percentage by weight: 3-8 parts of MBS (methyl methacrylate-butadiene-styrene) multi-block copolymer, 2-6 parts of a nano-state mesoporous material, 0.5-3 parts of an efficient antibacterial agent and 0.5-3 parts of a lipophilicity improver. The obtained PC / ABS alloy material has good spraying-free, high-gloss and metallized surface effects, the multi-angle glossiness of the PC / ABS alloy material is basically kept at 80 or above, the broad-spectrum antibacterial rate of the material is 95% or above, the surface tension is also reduced to about 32-34, and the obtained spraying-free PC / ABS alloy material has a good fingerprint contamination prevention effect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a spray-free polycarbonate alloy material with high antibacterial and anti-fingerprint properties and a preparation method thereof. Background technique [0002] Polycarbonate (referred to as PC resin, bisphenol A PC) is a highly linear thermoplastic polymer material with flexible carbonate groups and rigid benzene ring groups on the main chain. Such a molecular chain structure gives PC materials Good rigidity, heat resistance, and excellent notch impact resistance, and more importantly, PC resin has excellent aesthetic effects, and its high gloss has become the preferred choice for injection molding parts for aesthetic decoration in the fields of automobiles and home appliances. Preferred substrate. [0003] With the continuous development of the current social and economic level, people's demand for high-performance and multi-functional materials is becom...
