Abstract

The invention provides a polyvinyl chloride composite material with microwave absorption property and a preparation method thereof, and belongs to the technical field of novel materials. The problems of poor microwave absorption property and narrow frequency range in the prior art are solved. The polyvinyl chloride composite material with microwave absorption property consists of 100 parts of polyvinyl chloride (PVC) premix compound, 0.5-5 parts of multiwalled carbon nanotubes and 10-50 parts of nickel-plated carbon fibers, wherein the PVC premix compound consists of 100 parts of PVC resin, 1-5 parts of heat stabilizer, 30-70 parts of plasticizer, 0.5-2 parts of lubricant and 0.1-4 parts of processing addictive. The preparation method comprises the steps of premixing the PVC material and banburying. The polyvinyl chloride composite material with microwave absorption property is wide in sources of raw materials, low in cost, good in microwave absorption property, wide in absorption frequency, simple in production procedures, and suitable for industrial production.

Description

technical field

[0001] The invention relates to a polyvinyl chloride composite material and a preparation method thereof, in particular to a polyvinyl chloride composite material with microwave absorption characteristics and a preparation method thereof, belonging to the technical field of new materials. Background technique

[0002] Microwaves refer to electromagnetic waves with a frequency of 300MHz-300GHz. Microwaves not only have problems such as electromagnetic radiation and electromagnetic interference, but also have adverse effects on human health. The use of materials to absorb microwaves is an important means of controlling microwave electromagnetic pollution. Microwave absorbing materials are capable of absorbing electromagnetic wave energy projected onto its surface, and are required to meet performance characteristics such as strong microwave absorption, wide absorption frequency range, light weight and thin thickness. Combining polymer materials with good proce...
