Anti-static thermoplastic elastomer alloy material

Abstract

The invention provides an anti-static thermoplastic elastomer alloy material. A preparation method of the anti-static thermoplastic elastomer alloy material is characterized in that thermoplastic elastomers, a styrene copolymer, a compatilizer, an antistatic agent, a processing lubricant, an antioxidant, a light stabilizer and filler are added to a high mixing machine to be premixed for 10 min, the mixture is plasticized, extruded and graduated by a double-screw extruder, and the anti-static thermoplastic elastomer alloy material with excellent weather fastness and low dielectric constant is obtained. According to the anti-static thermoplastic elastomer alloy material, the thermoplastic elastomers and the styrene copolymer are uniquely utilized and directly blended, the environment-friendly material with low dielectric constant, low dielectric loss, high weather fastness and excellent dust-proof, antistatic and mechanical performance is obtained, defects that the dielectric performance, the weather fastness, the mechanical performance, the environmental protection requirements and the like of conventional materials in the antenna industry at present cannot be all considered are overcome, and the anti-static thermoplastic elastomer alloy material is innovatively applied to the communication antenna industry, building materials, gardening equipment and other industries.

Description

technical field [0001] The invention belongs to the field of materials, in particular to an antistatic thermoplastic elastomer alloy material. Background technique [0002] The communication system uses the vibrator and other radiating components in the antenna to transmit electromagnetic wave signals to transmit information. Engineering systems such as radio communication, radio / television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, and WIFI that are encountered in daily life are all communication systems. system. The antenna plays a central role in the entire communication system. During the installation and use of the antenna, in order to protect the radiating part from being damaged or interfered by the outside world, a protective shell is usually set outside the radiating part. Surrounded for protection. In order to maximize the effectiveness of the antenna, it is required that the antenna shell has as little influence on the trans...

AI Technical Summary

Problems solved by technology

Although PVC material has many advantages, it also has defects such as poor heat resistance (heat distortion temperature of about 60°C), relatively high dielectric constant (3-4.8), relatively low strength, and natural color containing halogen.

In addition, thermoplastic materials commonly used in antenna housing materials include acrylonitrile-butadiene-styrene copolymer (ABS), graft copolymer of acrylic rubber, acrylonitrile and styrene (ASA), impact-resistant polystyrene Styrene (HIPS), high polymer polypropylene (PP) and other materials, ABS and PS materials have a dielectric constant of 2.8-3.0 and are cheap. Because their molecular structure contains unsaturated double bonds, they are not suitable for outdoor applications.

ASA has excellent weather resistance and is the material of choice for outdoor applications, but the dielectric constant of ASA is between 2.8-3.3, and the cost is high, which limits its large-scale use

PP material has a dielectric constant of about 2.2, low density and low cost, but its low strength and poor aging resistance also limit its use
