The popularity of the term “environmental protection” has remained high for the past two years. As the national environmental protection efforts continue to increase, more and more environmentally friendly rubber products are produced. A large part of the rubber products in the market are made of natural rubber as the main raw material. However, the price of natural rubber has been fluctuating and falling, and often caught off guard, so many natural rubber products manufacturers have turned their attention to recycled rubber. However, more people's eyes are not able to use recycled rubber in environmentally friendly rubber products. Can rubber products with natural rubber as the main raw material really not use recycled rubber?
1. Why do many people think that recycled rubber cannot produce environmentally friendly rubber products?
Environmentally friendly rubber products require that the rubber used must not contain carcinogenic or other harmful substances, and cannot produce harmful gases during production and use. Tire reclaimed rubber is the most used product in reclaimed rubber products. It is processed from waste tires. Traditional tire reclaimed rubber will use coal tar, aromatic oil, etc. in the process of processing. A large number of toxic substances in the production, its composition The content of polycyclic aromatic hydrocarbons in the environment is higher than the international standard, so reclaimed rubber cannot be used in environmentally friendly rubber products.
2. Renewable rubber types that can be selected in environmentally friendly natural rubber products
At present, with the continuous upgrading and transformation of reclaimed rubber production technology and production equipment, the reclaimed rubber produced by many reclaimed rubber manufacturers controls the content of harmful substances such as polycyclic aromatic hydrocarbons within a certain range to meet international environmental protection standards; Many reclaimed rubbers appear in environmentally friendly natural rubber products. The eco-friendly latex reclaimed rubber and the environmentally-friendly tire reclaimed rubber in the reclaimed rubber product have good blending effect with natural rubber, and can be used in the production of environmentally-friendly natural rubber products to reduce the production cost.
3. Is the environmental protection test unqualified in environmentally friendly natural rubber products mixed with reclaimed rubber caused by the quality problem of reclaimed rubber?
Even if the reclaimed rubber used in environmentally friendly natural rubber products meets environmental standards, it does not mean that environmentally friendly rubber products that meet relevant standards can be produced. There are two ways to reduce the cost of natural rubber. One is to use reclaimed rubber, and the other is to fill a large amount of filler. In the case of rubber filler, if the filler used in natural rubber products contains heavy metals or carcinogens, even reclaimed rubber It is environmentally friendly and cannot produce qualified environmentally friendly natural rubber products. Natural rubber products need to be used in combination with various vulcanizing agents, plasticizers, anti-aging agents, etc. Any unqualified raw materials or mutual reaction to produce harmful substances will cause quality problems in finished products.
In summary, environmentally friendly natural rubber products can use reclaimed rubber products, but care must be taken in the selection of raw materials. It is necessary to choose environmentally-friendly reclaimed rubber with formal inspection reports, and pay attention to the types of various compounding agents in the formula. The amount and the relationship between each other are used to reduce the production cost of environmentally friendly natural rubber products while ensuring the quality of the products. Later, Xiaobian will discuss with you the selection skills of various compounding agents in environmentally friendly rubber products. Are you interested?
