Abstract

The invention provides a thermoplastic elastomer alloy material and a preparation method thereof. The thermoplastic elastomer alloy material consists of the following components in parts by weight: 10 to 40 parts of a thermoplastic elastomer, 41 to 89 parts of a styrene copolymer, 0 to 3 parts of a compatilizer, 0.5 to 4 parts of a processing lubricant, 0.2 to 0.5 part of an antioxidant, 0.3 to 1.5 parts of a light stabilizer and 0 to 10 parts of fillers. According to the thermoplastic elastomer alloy material, the thermoplastic elastomer and the styrene copolymer are creatively utilized to be directly blended to obtain a material with low dielectric constant, low dielectric loss, high weather resistance, low density, excellent mechanical property and environmental friendliness, the defect that the dielectric property, the weather resistance, the mechanical property, the environment-protecting requirement and the like of the common materials in the current antenna industry cannot all be taken into consideration is overcome, and the product provided by the invention is originally applied to communication antenna industry and industries of building materials, garden equipment and the like.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a thermoplastic elastomer alloy material and a preparation method thereof. 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 s...
