Abstract

The aramid pulp pretreatment process in the present invention relates to a pretreatment process insulating the surface of aramid pulp fibres with isolation medium. The used isolation medium contains inorganic isolation powder and lubricant, the inorganic isolation powder is mixed with incompact aramid pulp mixture and then with lubricant to prepare aramid pulp composite. In every 100 weight parts of aramid pulp composite, there are 20-30 parts of aramid pulp, 37.5-62.5 parts of inorganic isolation powder, and 10-40 parts of lubricant. The inorganic isolation powder is hollow glass microbeads of 1250- 5000 mesh and the lubricant is phthalate ester compound. The prepared aramid pulp composite is a homogeneous and stable fibre composite, the aramid pulp fibres in it disperse well in the elastomer matrix facilitating the enhancement of the performance of the elastomer composite materials.

Description

technical field

[0001] The invention relates to a method for pretreating the surface of aramid pulp, which is a pretreatment method for isolating the surface of aramid pulp fibers by using inorganic isolation powder and a lubricant. Background technique

[0002] Aramid pulp (Aramid Pulp, hereinafter referred to as AP) is a product of aramid fiber surface fibrillation first developed by DuPont in the United States in 1984. It is mainly used as an ideal substitute fiber for asbestos, competing with glass fiber and carbon fiber. It is used in the fields of sealing materials, reinforcing materials and friction materials. AP has high modulus, high strength, high temperature resistance, wear resistance, chemical corrosion resistance, dimensional stability, etc. AP has a very unique fiber structure: AP main fiber (length 1-3 mm, diameter 10-20 microns) attached There are a large number of ultrafine microfibrils with diameters between nanoscale and micronscale (0.1-1 micron in diam...
