Problems solved by technology

However, with this method, the glass fiber reinforced polyolefin after adding glass fiber has defects such as high density, poor wave transmission performance (large dielectric constant and dielectric loss), poor toughness, etc., which cannot meet the requirements for weight or wave transmission performance. high occasion use
In order to improve the wave-transmitting performance of polyolefin materials, some studies have used the method of adding low-dielectric glass fiber or quartz fiber. Although this method can achieve better wave-transmitting performance, it also has defects such as high density and high cost.

Embodiment 1-7 and comparative example 1-3

[0040] Mix the polyolefin resin and compatibilizer according to the ratio in Table 1, and add them to the main feeding system of the extruder, and at the same time add the reinforcing fiber and hollow mullite microspheres to the side feeding system, and mix all the components through the extruder The polyolefin material is obtained by extruding and granulating. The test results are shown in Table 1.

[0041] Each component distribution ratio (parts by weight) in the embodiment and comparative example of table 1

[0042]

[0043] Continuation of Table 1:

[0044]

[0045] It can be seen from Comparative Example 1 that only adding reinforcing fibers, although the strength of the material is significantly improved, but its density is relatively high, and its wave-transmitting performance is poor. In comparative example 3, only hollow mullite microspheres were added, although its density decreased and its wave-transmitting performance was significantly improved, but its st...

Abstract

The invention discloses a polyolefin material as well as a preparation method and application thereof. The polyolefin material comprises the following components: 15-95 parts of polyolefin resin, 5-60parts of reinforcing fibers, 0.5-10 part of a compatilizer, and 5-60 parts of hollow mullite microspheres. By adding the reinforcing fibers and the hollow mullite microspheres into the polyolefin material, the reinforcing fibers and the hollow mullite microspheres have a synergistic effect, so that the density of the material can be remarkably reduced, the wave-transparent performance of the material can be improved, the strength and heat resistance of the material can be improved, and the prepared polyolefin material has the advantages of high heat resistance, high strength, low density andhigh wave transparency.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a polyolefin material and its preparation method and application. Background technique [0002] Polyolefin materials are the most widely used in real life due to the characteristics of abundant raw materials, low price, easy processing and molding, and excellent comprehensive performance. [0003] At present, the reinforcement method of conventional polyolefin mainly uses glass fiber as a reinforcing medium, and utilizes the high strength and high rigidity of glass fiber to improve product strength and heat resistance. However, with this method, the glass fiber reinforced polyolefin after adding glass fiber has defects such as high density, poor wave transmission performance (large dielectric constant and dielectric loss), poor toughness, etc., which cannot meet the requirements of weight or wave transmission performance. Use on high occasions. In order to improve t...
