Product Description

Product use:

Synthetic dyes, pigments

P-phenylenediamine is an intermediate of azo disperse dyes, acid dyes, direct dyes and sulfide dyes. Adding 3% hydrogen peroxide turns the color black and 5% ferric chloride turns the color brown. It has a strong affinity for keratin in hair, and its oxidation process is the hair color fixation process. It is not only the most effective component of hair dye, but also the most potentially harmful substance to human health.

Synthetic resin

Aramid 1414 produced by condensation of p-phenylenediamine and terephthalic acid is a synthetic fiber with excellent properties and wide applications.

Polyamide-imine resin with good properties can be prepared by the reaction of p-phenylenediamine with Malay rosin monoacyl chloride. It can form film or draw wire. It is a kind of resin with great practical value.

Polymer Kevlar obtained by polycondensation of p-benzenediamine and p-benzeneyl chloride, which belongs to high temperature resistant polymer liquid crystal resin, is now used in the composite materials of supersonic aircraft.

The reaction of p-phenylenediamine with phosgene can produce its diisocyanate (PPDI), and then prepare polyurethane with high crystallinity. The product has excellent high temperature performance and can be used as thermoplastic and casting elastomer.

P-phenylenediamine reacts with aromatic dicarboxylic acids to form aromatic polyamides, resulting in fabrics that can be used as reinforcement materials for tires and V-tapes, as reinforcement materials for plastics, sports equipment, brake linings, and other items requiring high strength and modulus.

Rubber antiaging agent

P-phenylenediamine and the antiaging agent synthesized from p-phenylenediamine have good effect, and there are many varieties at home and abroad. It is mainly used as antiaging agent for natural rubber and diene synthetic rubber.

P-phenylenediamine can be directly used to prevent the aging of raw rubber. For example, the combination of p-phenylenediamine and organic acid cobalt salt is used in raw rubber. The raw rubber is used in the production of steel wire tire.

The condensation of p-phenylenediamine and furfural can also improve the adhesion of steel wire and rubber.

P-phenylenediamine and octanol-2 or the corresponding ketone condensation to get aging 288, is an excellent anti-ozone agent, effective for aging caused by oxygen and deflection, has protective effect on atmospheric exposure cracking, suitable for natural rubber and synthetic rubber.

Epoxidized vegetable oil and p-phenylenediamine condensation, the anti-aging performance is similar to 4010NA, but not volatile, no spray, solvent resistance is better than 4010NA.

Curing agent for epoxy resin

Using p-phenylenediamine as curing agent of epoxy resin alone does not show any advantage, but using p-phenylenediamine modified phenolic resin to cure epoxy resin, the cured product has good heat resistance and chemical resistance, and the heat resistance is 50℃ higher than that of phenolic resin.
