High-performance meta-aramid / mica composite insulation paper, preparation method and application

PendingCN122280007Aretain mechanical propertiesRetain high temperature resistancePolymer sciencePapermaking
This invention discloses a high-performance meta-aramid / mica composite insulating paper and its preparation method. The paper is formed by wet papermaking and hot pressing of a mixed slurry composed of meta-aramid chopped fibers, meta-aramid precipitated fibers, and mica flakes. The composite insulating paper has a thermal decomposition temperature ≥425℃, tensile strength ≥52N / mm, tear strength ≥2.2N / mm, and voltage breakdown strength ≥13.8kV / mm. The mass ratio of chopped fibers to precipitated fibers is (50~80):(50~20). The amount of mica flakes added is 5wt%~10wt% of the total mass of the two aramid fibers. The hot pressing adopts a segmented hot pressing process of "low-temperature pre-pressing - medium-temperature strengthening - high-temperature setting". By controlling the key parameters of the precipitated fibers and optimizing the ratio of chopped fibers to precipitated fibers and the proportion of mica flakes added, the paper is prepared through processes such as raw material pretreatment, graded mixing and dissociation, wet papermaking, and segmented hot pressing. Advantages: Through multi-parameter coordinated control and process optimization, the technical bottlenecks such as the mechanical and insulation properties of existing aramid composite insulating paper and insufficient thermal stability have been solved.

PendingCN122082058AGuarantee the reliability of useFill or block microscopic poresCellsConstructions elementsUltrasonic vibrationAir tightness
This invention discloses a five-layer electrodeposited high-sealing corrugated pipe based on ultrasound assistance and its preparation method, belonging to the technical field of metal corrugated pipe manufacturing. It aims to solve the problem that in multi-layer electrodeposited corrugated pipes, it is difficult to effectively coordinate current density, surface quality, and interfacial bonding strength, leading to insufficient densification of the deposited layer, unstable interlayer bonding, poor wall thickness uniformity, and failure to meet airtightness standards, ultimately resulting in poor overall performance stability. This invention includes a five-layer composite structure in which the pipe wall is composed of alternating nickel-cobalt alloy and copper layers. Each layer of the five-layer composite structure undergoes ultrasonic vibration treatment during deposition. The corrugated pipe prepared by this invention has a uniform and dense deposited layer with good interlayer bonding. The five-layer alternating deposition layer composite structure not only achieves uniform stress transmission and dispersion, effectively delaying crack propagation and interfacial penetration, but also improves the uniformity of wall thickness distribution, enabling the corrugated pipe to exhibit higher structural stability and long-term reliability in a sealed environment.
