Embodiment 1
[0067] A kind of regenerated latex and preparation method thereof:
[0068] A. Sorting, arranging and classifying the waste latex, and shearing and pulverizing through open rubber mixing or open groove roller rubber breaker. The particle size of the pulverized rubber material is 4 mesh granular or small block ;
[0069] B. Put 39kg of the crushed rubber into a self-heating mixer and stir. When the temperature rises to 70°C, add 50kg of desulfurizer and 1.5kg of ethylenediamine as the catalyst under constant stirring. Catalyst is methacrylic acid 1.5kg, softening agent is rosin 0.5kg, constantly stirs;
[0070] C. When the temperature in the mixer reaches 90°C, add 0.5kg of phthalic anhydride and 1kg of heavy magnesium oxide as plasticizers;
[0071] D. When the temperature reaches 110°C, after adding 1.6kg of active modifier rosin, when the temperature reaches 110°C, the reaction time is 5 minutes, the reaction is terminated, and the material is discharged and cooled;

Embodiment 2
[0088] A kind of regenerated latex and preparation method thereof:
[0089] A. Sorting, arranging and classifying the waste latex, and shearing and pulverizing through open rubber mixing or open groove roller rubber breaker. The pulverized rubber material has a particle size of 20 meshes or small pieces .
[0090] B. Put 80kg of the crushed rubber into a self-heating mixer and stir. When the temperature rises to 90°C, add 15kg of desulfurizer, 3kg of ethylenediamine as the catalyst, and 3kg of co-catalyst 0.5kg of methacrylic acid, 1.5kg of rosin as softener, stirring constantly;
[0091] C. When the temperature in the mixer reaches 130°C, add 0.8kg of phthalic anhydride and 0.7kg of heavy magnesium oxide as plasticizers;
[0092] D. When the temperature reaches 140°C, add 3.5kg of rosin as an active modifier, and when the temperature reaches 150°C, the reaction time is 12 minutes, the reaction is terminated, and the material is discharged and cooled;
[0093] E. Discharge ...
Embodiment 3
[0109] A kind of regenerated latex and preparation method thereof:
[0110] A. Sorting, arranging and classifying the waste latex, and shearing and pulverizing through open rubber mixing or open groove roller rubber breaker. The pulverized rubber material has a particle size of 10 meshes or small pieces with silk .
[0111] B. Put 50kg of crushed rubber into a self-heating mixer and stir. When the temperature rises to 80°C, add 45kg of desulfurizer in turn under constant stirring. The catalyst is 2kg of ethylenediamine, and the cocatalyst 0.6kg of methacrylic acid, 1kg of rosin as softener, stirring constantly;
[0112] C. When the temperature in the mixer reaches 110°C, add 0.6kg of phthalic anhydride and 0.9kg of heavy magnesium oxide as plasticizers;
[0113] D. When the temperature reaches 120°C, add 2.5kg of rosin as an active modifier, and when the temperature reaches 130°C, the reaction time is 8 minutes, the reaction is terminated, and the material is discharged and ...
