Background
With the rapid development of society and economy, the demand of rubber is increasing. In daily life, rubber gains a very large market share by virtue of its excellent physicochemical properties. The rubber has wide application fields in various rubber gaskets and soles commonly used in life, rubber gloves and guide pipes in medical experimental articles, tires, conveyor belts and the like widely used in the transportation industry. However, the covalent network structure formed by vulcanization and crosslinking of rubber is insoluble and infusible, so that the rubber is difficult to recycle, which not only causes a great deal of rubber resource waste, but also brings about serious black pollution and influences the living environment of human beings. Therefore, the effective recycling of the waste rubber has great significance. At present, the waste rubber is recycled mainly by means of desulfurization treatment by physical, chemical or biological technologies and then is formed into regenerated rubber. However, these desulfurization processes not only require a large amount of energy consumption, but also generate a large amount of wastewater and exhaust gas, which causes secondary pollution to the environment, and do not conform to the principle of green chemistry. In recent years, different dynamic chemistries are introduced into a vulcanized rubber system to realize solid phase recycling of vulcanized rubber, for example, chinese patent CN105086326A discloses a hydrogen bond-ionic bond interpenetrating thermoreversible crosslinked rubber, which is subjected to hydrogen bond-ionic bond breakage at high temperature, and the opened hydrogen bond-ionic bond can be reformed again at low temperature, so that the vulcanized rubber exhibits thermoplastic processability, but the method needs to perform grafting modification of maleic anhydride, and uses alkylamine as a crosslinking agent for vulcanization; the grafting modification needs additional investment, and alkylamine has certain biological toxicity; the whole preparation method is too complicated and is not beneficial to industrial production.

As can be seen from the above table 1, in general, the regenerated rubber material prepared by the method of the present invention has certain mechanical strength and damping performance, and as the particle size of the rubber powder is reduced, the larger the specific surface area is, the stronger the interaction between the particles is, and the higher the mechanical property (tensile strength) of the regenerated rubber is; the damping performance of the regenerated rubber is higher along with the increase of the use amount of the hindered phenol; the mechanical strength of the regenerated rubber can be increased by increasing the consumption of the multi-sulfhydryl compound in a proper amount; the functionality of the multi-mercapto compound is increased, and the mechanical strength of the reclaimed rubber can be improved. The samples in the comparative example 1 lack the basic catalyst, while the samples in the comparative example 2 lack the multi-sulfhydryl compound, which causes the sulfhydryl-alkene reaction to be difficult to be rapidly and effectively carried out, thereby causing the interface of rubber powder particles to lack the covalent crosslinking effect, and the prepared regenerated rubber has weak mechanical strength, so that the damping temperature is difficult to detect, and the tensile strength and the elongation at break are not as good as those of the solid-phase regenerated rubber materials prepared in the examples. Therefore, the invention has certain application value and can realize solid phase recycling of the waste rubber.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
