2. Definition of "environmentally friendly"
Low VOCs emissions, reducing air pollution to the environment.
Easily degradable or recyclable, reducing environmental burden.
Green synthesis route, reducing resource consumption and pollution in the production process.
3. Industry standards and certification system
International standards: ISO 14000 environmental management system, OEKO-TEX, GOTS, etc.
Local standards: EU REACH, US TSCA, China's environmental protection policy, etc.
Enterprise standards: green supply chain management and green product certification.
4. Technical challenges faced by "non-toxic and environmentally friendly" additives
1. The balance between performance and environmental protection
The performance of many environmentally friendly additives cannot completely replace traditional additives, especially in key performance such as vulcanization efficiency, aging resistance, and ozone resistance.
The stability and processing adaptability of some environmentally friendly additives are insufficient, which may affect the quality and service life of rubber products.
2. R&D cost and industrial chain adaptation
The R&D investment of green additives is large and the cycle is long, and enterprises, especially small and medium-sized enterprises, are under great pressure.
The supporting industrial chain and raw material supply are not yet perfect, which limits the large-scale promotion of non-toxic and environmentally friendly additives.
3. The synchronization of regulatory updates and technological research and development
The regulatory iteration speed is fast, and it is difficult for enterprises to quickly adjust products and processes.
The technology is not mature enough, and some environmentally friendly additives are still in the stage of trial and small-scale application.
5. Industry development status and typical cases
1. Promotion and application of environmentally friendly additives
In the field of vulcanizing agents: some companies develop low-volatile sulfur and peroxide vulcanization systems to reduce environmental pollution.
Antioxidants and antiozonants: Green alternatives such as phenolic environmentally friendly antioxidants gradually replace traditional amine antioxidants.
Synergists and coupling agents: Silane coupling agents are used to improve filler utilization and reduce the amount of chemical additives.
2. Promotion by leading enterprises and scientific research institutions
Large tire manufacturers and additive manufacturers have invested heavily in the development of environmentally friendly additive products, forming a certain market scale.
Scientific research institutions in various countries have conducted in-depth research on green synthesis processes and additive biodegradability.
