Unsaturated resin polymerization inhibitor
Principle of action
The principle of action of MTBHQ as a polymerization inhibitor for unsaturated resins is based on the hindered hydroxyl group in its molecular structure. In the presence of free radicals, MTBHQ is able to rapidly react with them in an addition reaction, thus consuming them and preventing them from further triggering the polymerization of the resin. This rapid reaction capability enables MTBHQ to effectively inhibit the polymerization reaction during storage and production of the resin, maintaining the stability and processability of the resin.
The unsaturated resin polymerization inhibitor MTBHQ (2-tert-butylhydroquinone) plays an important role in resin synthesis and other synthetic reactions. The following is a detailed analysis of its principle of action and effects:
Effect
Remarkable polymerization inhibition effect:
MTBHQ is a kind of high efficient polymerization inhibitor for unsaturated resin. Under normal storage conditions, the general addition amount is only two ten-thousandths of the total amount of resin, and it can play a good effect of polymerization inhibition. This low additive amount and high efficiency make MTBHQ has a wide range of application prospects in resin production.
MTBHQ's polymerization inhibition effect is stable and long-lasting, and the stability of anti-resin hardening can be more than half a year. This is of great significance for the storage and transportation of resin.
Good thermal stability:
MTBHQ has good thermal stability and can maintain its polymerization blocking effect in a wide temperature range. Even at high temperatures, the polymerization blocking effect of MTBHQ is not significantly weakened, which makes it more advantageous in the production of high-temperature curing resins.
Unaffected by the environment:
MTBHQ's polymerization blocking effect is not affected by temperature or environment. MTBHQ is able to perform effectively as a polymerization barrier in both oxygenated and oxygen-free containers. This property allows MTBHQ to maintain stable performance under various storage and production conditions.
Low impact on resin properties:
MTBHQ inhibits resin polymerization while having a low impact on the final cure rate of the resin. This means that under the action of the resin initiation system, MTBHQ does not significantly affect the curing performance of the resin, thus ensuring the quality and performance of the resin products.
Wide range of applications:
In addition to being used as a polymerization inhibitor for unsaturated resins, MTBHQ can also be used as an antioxidant and antioxidant in the rubber and plastics industry, as an antioxidant in oils and fats, and as an antioxidant in the fields of pigments, dyes, and pharmaceutical intermediates. These application fields fully demonstrate the versatility and practicality of MTBHQ.
In summary, MTBHQ has remarkable effect and wide application prospects as a polymerization inhibitor for unsaturated resins. Its high efficiency, stability, good thermal stability, independence from the environment and low impact on resin properties make MTBHQ valuable in resin synthesis and other synthetic reactions.
