Problems solved by technology

Generally speaking, for products with low quality requirements, about 100 parts by weight or higher of reclaimed rubber powder with a particle size of 40 mesh can be added, but for medium and high-quality products (such as tires), only about 10 to 20 parts by weight can be added Reclaimed rubber powder whose particle size is below 100 mesh, and if the reclaimed rubber powder is finer, the addition amount can be increased, but the relative physical properties are also poor
It can be seen that, in addition to the complicated production process and the need to use chemical reagents, reclaimed rubber has not yet been able to completely replace natural rubber or other plastic materials, and the scope of application still needs to be expanded.

Embodiment 1

[0037] [Example 1] Preparation of rubber particle composition

[0038] use figure 1 The high-speed jet fluid produced by the high-pressure jet fluid device (developed and assembled by the applicant of the present invention) impacts the waste tire waste (manufactured by Japan Dunlop Company, the model is SP350, the specification is 12R225, Steel Radial Tubeless, and the appearance shape is flake) , and control the Reynolds number of the high-speed jet fluid to be about 500,000, and the total output kinetic energy is 61×10 3 About kJ, after tens of seconds, the rubber particle composition can be obtained.

[0039] Make the rubber particle composition pass through the sieves of the following three sieve diameters to classify the particle size range: (i) 0.075~0.038mm, (ii) 0.15~0.075mm and (iii) 0.425~0.15mm, and finally obtain Compositions of rubber particles in three different particle size ranges:

Abstract

The invention provides a rubber particle composite which comprises a plurality of rubber particles, wherein at least a part of the surfaces of at least a part of the rubber particles are fractural planes in tension fracture, and the phenomenon of coke clusters is difficult to be observed. The invention also provides a preparing method of the rubber particle composite. The rubber particle composite can be used as the main rubber ingredient or the functional additive of a rubber product in follow-up step and is used with various rubber or polymer materials.

Description

technical field [0001] The invention relates to a rubber particle composition and a preparation method thereof, in particular to a rubber particle composition comprising a plurality of special rubber particles, and a preparation method of the rubber particle composition. Background technique [0002] Waste rubber products (such as waste tires, waste shoe soles, waste hoses, waste films, etc.) are mainly made of natural rubber or synthetic rubber after vulcanization and cross-linking. Generally, after recycling, they cannot be transformed into Reproducts with superior chemical or mechanical properties. Therefore, the early recycling method was to use mechanical processing to crush the waste rubber products into flakes, granules or powder, which is the so-called "recycled rubber powder", and then directly buried it as the asphalt for filling the road surface. Additives or further melting to make low-specification materials (such as rubber mats, car fenders, etc.). This kind ...
