Description
Technical Field
The invention relates to the technical field of unsaturated polyester resin material synthesis, in particular to a wave-transparent unsaturated polyester resin material and a preparation method thereof.
Background
Compared with an inorganic wave-transparent composite material, the resin-based wave-transparent composite material has a good development prospect and economic benefits. Different structural forms can be designed by utilizing the resin-based wave-transmitting composite material to meet the requirements on the mechanical properties of the material. Meanwhile, the content of each raw material of the composite material can be accurately controlled according to the requirement of wave-transmitting performance, wherein the dielectric performance and other performances of the composite material can be properly designed and adjusted, so that the resin-based composite wave-transmitting material is favored by scientific researchers. At present, resin-based composite wave-transmitting materials are divided into the following categories according to the difference of resin bases:
(1) epoxy resin based wave-transparent composite material
The epoxy resin molecular structure contains epoxy functional groups capable of reacting with various curing agents, so that the epoxy resin molecular structure has good cohesiveness and wear resistance, the process is relatively mature, the wave-transparent composite material prepared by using the epoxy resin molecular structure has low cost, stable size and compact material structure, but the epoxy resin-based wave-transparent composite material has low heat resistance and cannot meet the heat resistance requirement of an aircraft under high Mach number conditions; the impact toughness and the resistance to moist heat are also poor, and the dielectric constant and the dielectric loss value are large.
(2) Cyanate resin-based wave-transparent composite material
The cyanate resin molecules contain two or more cyanate functional groups, cyclization reaction can occur between the cyanate resin molecules at a certain temperature, and finally the cross-linked network macromolecule containing triazine ring is produced. The triazine ring has a highly symmetrical structure, has weak polarizability and does not have dipole moment, so the triazine ring has excellent dielectric properties, namely, the low dielectric constant epsilon is 2.8-3.1F/m, the extremely small dielectric loss (tan delta) is 0.009-0.005, and the glass transition temperature T of the cyanate resingOver 240 ℃. However, the curing process of preparing the wave-transparent composite material by using the cyanate ester resin needs higher curing temperature, but the toughness of the material is greatly reduced by high-temperature curing, the brittleness is higher, and meanwhile, the production cost of the wave-transparent composite material is higher.
(3) Polyimide resin-based wave-transmitting composite material
The polyimide resin is a polymer containing aromatic rings and imide groups on a main chain, has high heat resistance, can resist heat up to 366 ℃, has dielectric property epsilon of 4.1F/m and dielectric loss (tan delta) of 0.008, has good mechanical property, chemical resistance and high dimensional stability, but has curing temperature higher than 300 ℃ when the polyimide resin is used for preparing the wave-transparent composite material, increases the production cost, and has harsh process conditions, thereby bringing certain difficulty to the wide application of the polyimide resin.
(4) Bismaleimide resin-based wave-transmitting composite material
The bismaleimide is one of resin systems derived from polyimide, has good electrical insulation performance, chemical corrosion resistance and high temperature resistance, has the working temperature of 100-250 ℃, and has poor toughness due to the fact that the bismaleimide is used for preparing the wave-transmitting composite material because of the heat resistance of the multifunctional epoxy resin.
(5) Unsaturated resin-based wave-transparent composite material
The unsaturated polyester resin contains a large amount of crosslinked thermosetting plastics in the molecular structure, and the unsaturated bonds are initiated to react by an initiator under proper conditions to generate the crosslinked thermosetting plastics. The wave-transparent composite material prepared by using the unsaturated polyester resin has certain mechanical property and electrical property, but self-polymerization curing is easy to occur in the synthesis process, and the prepared material has the abnormal phenomena of stickiness, generation of a large amount of bubbles and the like, so that the dielectric property and the mechanical property of the wave-transparent composite material are greatly reduced. Meanwhile, the prepared unsaturated polyester resin-based wave-transmitting composite material has poor high-temperature resistance and is easy to ablate.
Based on the fact that the wave-transmitting performance of the existing unsaturated polyester resin material is unstable, and the dielectric property and the mechanical property of the unsaturated polyester resin material are relatively low, the unsaturated polyester resin material with excellent wave-transmitting performance is provided.
