Epoxy resin curing accelerator DMP-30 is 2,4,6 tris(dimethylaminomethyl)phenol, which is a tertiary amine curing agent. It can be used as an epoxy resin curing agent at room temperature, and also as an efficient accelerator for acid anhydride, polyvinylamine and aliphatic polyamine curing agents.

This product contains phenolic hydroxyl group in its molecular structure, so the activity is increased and it can be used for fast curing, mainly for thermosetting epoxy resin curing agent and adhesive, and it can be used as accelerator of acid anhydride curing agent and amide curing agent for casting and pressure layer products, the amount of this product as curing agent is generally about 3-13%, and the amount as accelerator is generally 0.1-3%. This product can be used as a catalyst in rubber anti-ozone agent and rigid polyurethane foam raw material combination polyether.

Production process.

2000L reaction kettle, 200kg of phenol, 720kg of dimethylamine, 520kg of formaldehyde added dropwise below 50 degrees.

kg, after drop addition, raise the temperature to 70 degrees, keep warm for 2 hours, lower the temperature to 50 degrees, add 100 kg of sodium chloride

Sodium chloride, stir, let stand, stratify, and dehydrate the crude product under pressure.

Method of preparation.

After the reaction of phenol with dimethylamine and formaldehyde, the reaction products are stratified, dehydrated under vacuum and filtered to obtain the finished product.

Theoretical unit consumption: (one ton of product)

Phenol: 400 kg

Dimethylamine (40% aqueous solution) 1440kg

Formaldehyde (37% aqueous solution) 1040kg

Produce waste water about 1.8 tons, mainly containing a small amount of formaldehyde

Dosage:

As accelerator dosage is about 1~5%

As a curing agent dosage of about 10%
