Aramid pulp dispersion and friction material
The invention relates to the technical field of friction materials, in particular to an aramid pulp dispersed material and a friction material. The aramid pulp dispersed material is prepared from the following raw materials in parts by weight: 100 parts of aramid pulp, 2-20 parts of modified liquid and 600-1200 parts of inorganic powder, wherein based on the total mass of the modification liquid, the modification liquid comprises a solvent, 1 to 5 weight percent of a surfactant, 0.5 to 3.5 weight percent of a coupling agent and 0 to 3 weight percent of a tackifier. In the invention, the inorganic powder and a small amount of modified liquid have a synergistic effect, so that the aramid pulp can be efficiently dispersed by a dry method, the production process can be simplified, the production cycle can be shortened, and the aramid pulp dispersed material with excellent dispersity can be obtained.
本发明涉及摩擦材料技术领域，具体涉及一种芳纶浆粕分散料和摩擦材料。所述芳纶浆粕分散料的制备原料包括：100重量份的芳纶浆粕，2‑20重量份的改性液和600‑1200重量份的无机粉料；其中，以所述改性液的总质量计，所述改性液包括溶剂、1‑5wt％的表面活性剂、0.5‑3.5wt％的偶联剂和0‑3wt％的增粘剂。在本发明中，无机粉料和少量改性液协同作用，可以实现干法高效分散芳纶浆粕，能简化生产工艺，缩短生产周期，获得分散性极佳的芳纶浆粕分散料。
