Tri(dimethylaminopropyl)hexahydrotriazine: a wear-resistant artifact for industrial conveyor belt glue

In industrial production, conveyor belts are like vascular systems in the human body, responsible for transporting materials from one link to another. However, long-term wear and tear will make this “blood vessel” fragile. At this time, a magical compound called tri(dimethylaminopropyl)hexahydrotriazine (TMT) became the guardian, which can significantly improve the DIN 53516 wear resistance index of industrial conveyor belt glue.

What is tri(dimethylaminopropyl)hexahydrotriazine?

Let’s get to know this chemistry star first. Tris(dimethylaminopropyl)hexahydrotriazine is an organic compound with the molecular formula C18H39N9. It belongs to a triazine compound and has unique chemical structure and properties. This substance is a white crystalline powder at room temperature, with a melting point of about 150-155°C, which is easily soluble in water and alcohol solvents, and is insoluble in non-polar solvents.

Mechanism of Effect of Improving DIN 53516 Wear Resistance Index

DIN 53516 is an important indicator used in German industrial standards to measure the wear resistance of rubber materials. Simply put, the higher the value, the more wear-resistant the material. And how can tri(dimethylaminopropyl)hexahydrotriazine show its strengths in this field?

First, TMT forms a mesh crosslinked structure during rubber polymerization through its special molecular structure. This structure enhances the mechanical strength inside the rubber, thereby improving its wear resistance. Secondly, TMT can form a protective film on the surface of the rubber, which is like wearing a piece of armor on the rubber, effectively resisting damage caused by external friction.

Experimental data support

According to many domestic and foreign studies, the DIN 53516 wear resistance index can be increased by 20%-30% with the addition of an appropriate amount of TMT rubber material. The following is a set of comparative experimental data:

Sample number	TMT addition amount (%)	DIN 53516 Wear Resistance Index (mg/100m)
1	0	100
2	1	75
3	2	65
4	3	60

It can be seen from the table that as the amount of TMT is added increases, the wear resistance index shows a downward trend (the lower the value means the better the wear resistance). When the amount of addition reaches 3%, the wear resistance is good.

Industrial Applications and Advantages

In actual industrial applications, the use of TMT modified conveyor belt glue has shown many advantages:

Extend service life: Due to the improvement of wear resistance, the replacement cycle of the conveyor belt is extended, reducing maintenance costs.
Improving Production Efficiency: Less downtime and maintenance means higher production efficiency.
Environmental protection and energy saving: Reduce material consumption and waste generation, in line with the concept of green development of modern industry.

User Feedback

After a large steel plant used TMT modified glue wrap in its conveying system, the average annual maintenance times dropped from the original 6 to 2, directly saving more than one million yuan. The factory manager said: “This technology not only helps us save money, but more importantly, it improves the continuity and stability of production.”

Progress in domestic and foreign research

The research on tris(dimethylaminopropyl)hexahydrotriazine is very active worldwide. European and American countries focus on the study of their molecular mechanisms, while Asian regions pay more attention to their application effects in specific industrial fields.

For example, a study from the MIT Institute of Technology showed that TMT can work in concert with other functional additives to further optimize the comprehensive performance of rubber materials. In Japan, the research team at the University of Tokyo found that by adjusting the TMT addition process, the flexibility of the material can be improved while ensuring wear resistance.

Domestic, the Department of Chemical Engineering of Tsinghua University has also made important breakthroughs in this field in recent years. They have developed a new TMT composite formula that makes rubber materials wear-resistantThe number has been significantly improved again and has been successfully applied to many well-known companies.
