The invention discloses a vulcanized rubber reclaimed rubber and a preparation method thereof, and belongs to the technical field of rubber. A regenerant is provided, can selectively break sulfur-sulfur bonds in vulcanized rubber at a low temperature, and is small in dosage and low in cost, and the molecular weight of the obtained reclaimed rubber is high. The preparation method comprises the following steps: mixing vulcanized rubber with the regenerant, swelling through a solvent, and keeping the decrosslinking temperature to make the regenerant permeate into a vulcanized rubber network for decrosslinking. A good selective chain breaking effect can be achieved on sulfur-sulfur bonds in waste rubber, large-amplitude chain breaking of the crosslinked network at the relatively low temperature is achieved, the cost of the regenerant is low, and the obtained regenerated rubber is high in sol content and molecular weight.

The invention provides a non-curable rubber asphalt waterproof paint modifier and a preparation method thereof. The modifier includes assistant dissolving oil, linearized active rubber and a rubber cross-linking assistant. The linearized active rubber is obtained by desulfurization treatment on waste rubber powder, wherein the weight percentage of linearized molecules is greater than or equal to 75%. The modifier can give full play to the low temperature flexibility and elasticity of rubber itself, and improve the comprehensive physical properties of non-curable waterproof paint. At the same time, the linearized active rubber exists in a room temperature half-flow state, after application to non-curable waterproof paint, the viscosity of the paint is low, so that the paint can be applied to construction in harsher environment at lower heating temperature, and the linearized active rubber and other components can form close interface bonding, thus improving the overall stress absorptioncapacity of the paint. In addition, the linearized active rubber has greatly weakened capability of swelling absorption of the assistant dissolving oil in the paint and the light components in asphalt, therefore the creep properties and initial adhesion of the paint can be improved.

The invention provides a method for regenerating a cross-linked network through low-temperature selectivity rupture of vulcanized rubber, belonging to the field of recycling of waste rubber resources. According to the method provided by the invention, firstly, after the vulcanized rubber and de-cross-linking assistants are mixed, solvent swelling is carried out, and the de-cross-linking temperature is kept; the vulcanized rubber is de-cross-linked through the interaction and matching of the de-cross-linking assistants, and a good selectivity rupture effect on sulfur-sulfur bonds in the waste rubber can be achieved; and at relatively low temperature, great rupture of the cross-linked network can be realized, thereby obtaining regenerated rubber with high sol content and high molecular weight.

The invention relates to a method for realizing rapid waste rubber powder depolymerization by using ultraviolet rays and belongs to the field of recycling of renewable resources. According to the method, a high-energy ultraviolet generator is used, a physical ray irradiation method is adopted, in the oxygen environment, different kinds of waste rubber powder are subjected to high-energy ultraviolet irradiation treatment, and a rubber 3D cross-linked network is broken in a short time, so that green depolymerization generation of the waste rubber powder is realized. The high-energy ultraviolet generator is used, and the method has the simple process and has the advantages that the depolymerization temperature is low, the depolymerization process is rapid, the recovery method is energy-saving and environment-friendly, the depolymerization degree is controllable and the performance of reclaimed rubber products is good.
