Problems solved by technology

However, the rigidity of the material is not high, resulting in limited ability of the product to withstand the force, and the stability of the resistance to environmental substances is not as good as PBT
In addition, products for outdoor operations must also be able to adapt to harsh environments, such as being able to effectively deal with problems such as flying dust and breeding bacteria. A single polyamide material or ASA material does not have antistatic, antibacterial and other functions

Embodiment Construction

[0025] Unless otherwise defined, the technical terms used in the following embodiments have the same meaning as commonly understood by those skilled in the art to which the present invention belongs. The test reagents used in the following examples, unless otherwise specified, are conventional biochemical reagents; the experimental methods, unless otherwise specified, are conventional methods.

[0026] The present invention will be described in detail below in conjunction with examples.

[0027] The raw materials selected in the following examples and comparative examples are specifically:

[0028] Among them, the PBT resin is PBT with high fluidity, and the melt flow rate is 25-40g / 10min (250°C, 10kg).

[0029] ASA resin is a copolymer of acrylonitrile-styrene-acrylic rubber, preferably a high-melt index type, with a melt flow rate of 15-25g / 10min (220°C, 10kg).

[0030] The antistatic agent is a permanent antistatic agent, including metal salt and polyoxyethylene; the pref...

Abstract

The invention provides an anti-static antibacterial PBT / ASA material and a preparing method and application thereof. The anti-static antibacterial PBT / ASA material is prepared from, by weight, 21-58 parts of PBT resin, 20-57 parts of ASA resin, 9-23 parts of an anti-static agent, 6-14 parts of wollastonite, 4-10 parts of methyl acrylate polymers, 1-3 parts of an antibacterial agent, 0.4-1.5 partsof a light stabilizer and 0.5-2 parts of a processing additive. The anti-static antibacterial PBT / ASA material combines PBT / ASA alloy materials and sufficiently exerts excellent performance of the twomaterials, and the weather resistance, the impact resistance and rigidity of the anti-static antibacterial PBT / ASA material are improved. In addition, the antibacterial agent and the anti-static agent are added innovatively, and thus the advantages of the anti-static performance and the antibacterial performance are both achieved.

Description

technical field [0001] The invention belongs to the field of modified materials for outdoor products, and in particular relates to an antistatic and antibacterial PBT / ASA material, a preparation method and an application thereof. Background technique [0002] Polybutylene terephthalate (PBT) material has the characteristics of high rigidity, low water absorption, acid, alkali, oil resistance, and easy processing. It is widely used in various indoor and outdoor fields. At present, many domestic enterprises widely use polybutylene terephthalate (PBT) materials, such as: electronic connectors, OA fans, lampshades, etc. However, polybutylene terephthalate material has poor toughness (notched impact strength is very low) and large shrinkage rate, and there are certain limitations in the shape and function design of many products. ASA (Styrene, Acrylonitrile, Acrylate Terpolymer) material is a common polymer. Because the acrylic rubber in the component does not contain double bon...
