Embodiment 1

[0118]Prepare 233 parts by weight of composite composition A masterbatch, wherein: the weight ratio of rubber powder and powder auxiliary materials to rubber is in the range of 133 / 100, and the weight ratio of rubber powder to powder auxiliary materials is in the range of 100 / 33. The specific steps are:

[0119] 1-1. Preparation of ultra-fine vulcanized rubber powder: 100 parts by weight of waste tire tread rubber particles of 20 to 30 mesh, thermal cracking carbon black 33 of waste tire side rubber and nylon miscellaneous fibers in waste tires finer than or equal to 200 mesh Parts by weight, add 0.033 parts by weight of nonionic surfactant (optional polyoxyethylene fatty alcohol ether), add 1 part by weight of stearic acid, mix with a stirrer, and the formula is pulverized by known normal temperature grinding disc fine rubber Machine pulverization, after processing with a cyclone classifier and a 100-mesh vibrating sieve, obtain about 133 parts by weight of vulcanized rubber p...

Embodiment 2

[0124] Prepare 155 parts by weight of composite composition A masterbatch, wherein: the weight ratio of rubber powder and powder auxiliary materials to rubber is in the range of 55 / 100, and the weight ratio of rubber powder to powder auxiliary materials is in the range of 100 / 450. The specific steps are:

[0125] 2-1. Preparation of superfine vulcanized rubber powder: use 10 parts by weight of 15-30 mesh waste tire tread rubber particles, 45 parts by weight of carbon black, and add 0.01 part by weight of anionic surfactant (optional sodium stearate) , after mixing with a stirrer, the formula is pulverized by a well-known room temperature disc-type fine rubber pulverizer, and then no need to use a cyclone classifier or a 100-mesh vibrating screen to obtain 99% finer than or equal to 100 mesh and mixed with surface rubber at one time. About 55 parts by weight of activating agent vulcanized rubber powder and powdered carbon black mixture are ready for use.

[0126] 2-2. Mixing an...

Embodiment 3

[0130] Prepare 160 parts by weight of composite composition A masterbatch, wherein: the weight ratio of rubber powder and powder auxiliary materials to rubber is in the range of 60 / 100, and the weight ratio of rubber powder to powder auxiliary materials is in the range of 100 / 250. The specific steps are:

[0131] 3-1. Preparation of superfine vulcanized rubber powder: use 20 parts by weight of waste tire tread rubber particles of 15-30 mesh, 10 parts by weight of white carbon black and 40 parts by weight of carbon black, add anionic surfactant (optional hard sodium fatty acid) 0.01 parts by weight, after mixing with a stirrer, the formula material is pulverized by a known normal temperature disc type fine rubber pulverizer, and then no need for classification and sieving process, just can get 89% finer than or equal to 100 mesh and mixed at one time There are about 60 parts by weight of the vulcanized rubber powder and powdered white carbon black and carbon black mixture of sur...

Abstract

The invention provides a latex mixing or solution mixing preparation method of a rubber powder-rubber compound composition, comprising the following steps of: mixing rubber powder, or rubber powder containing powder accessories, or sizing agent containing water or materials containing softening oil with rubber latex, or solution or undried solidified rubber to obtain rubber powder-rubber compound composition intermediate products, and then carrying out liquid removing treatment to obtain solid-state rubber powder-rubber compound composition products. The technical scheme provided by the invention obviously saves energy compared with the treatment process of kneading high-elasticity rubber micelle by utilizing the glue powder in the traditional rubber product industries, and greatly enhances the efficiency compared with the wet rubber drying process of the traditional rubber manufacturing. The provided rubber powder-rubber compound composition products enables up course, middle course and lower course of a rubber industrial chain to be tightly spliced, and then the entire industrial chain can receive the benefits of energy saving, emission reduction and synergia.

Description

technical field [0001] The invention proposes a method for preparing rubber powder-rubber compound composition by emulsification or mixing, which involves the recycling of waste rubber including waste tires and its combination with rubber powder auxiliary materials and rubber processing, and belongs to waste The technical category of rubber utilization and rubber preparation or emulsion mixing or blending masterbatch preparation in the rubber industry. Background technique [0002] As we all know, the vast majority of rubber products are not made of pure rubber. The traditional method is: firstly, the rubber factory extracts the emulsion from the rubber plant, and then the emulsion is demulsified, dehydrated, and processed. into solid natural rubber; or first refined from petroleum by petrochemical plants to prepare various polymer monomers such as styrene, isoprene, etc., and then polymerized to obtain emulsion or solution of synthetic rubber, and then further prepared Var...
