Chopped carbon fiber/carbon thermal field material and preparation method thereof
The invention provides a chopped carbon fiber/carbon thermal field material and a preparation method thereof. The light carbon fiber/carbon thermal field material blank material is prepared from the following raw materials in parts by mass: 100 parts of chopped carbon fiber I; 5 to 20 parts of short carbon fiber II; 10 to 30 parts of p-methylphenol; 10 to 30 parts of phenylacrolein; 0.3 to 0.9 part of an alkali solution; 1 to 3 parts of polymer powder; and 1-3 parts of a vinyl assistant crosslinker. The chopped carbon fiber/carbon thermal field material has the excellent properties of low density (0.12-0.20 g/cm < 3 >), excellent mechanical properties (the bending strength can reach 4.9 MPa), good thermal insulation property (0.1-0.3 W/(mK)), high purity (less than 5 ppm) and the like.
本发明提供一种短切碳纤维/碳热场材料及其制备方法。本发明制备轻质碳纤维/碳热场材料胚体材料的原材料组成及其质量份数包括：短切碳纤维I：100份；短切碳纤维II：5‑20份；对甲基苯酚：10‑30份；苯基丙烯醛：10‑30份；碱溶液：0.3‑0.9份；聚合物粉体:1‑3份；乙烯基助交联剂：1‑3份。所述短切碳纤维/碳热场材料具有密度低(0.12‑0.20g/cm3)、力学性能优越(弯曲强度可以达到4.9MPa)、保温性能好(0.1‑0.3W/(mK))、纯度高(＜5ppm)等优越性能。
