Active matrix additive in rubbers

The patented grinding method makes it possible to obtain particles of active matrix powder with a size of 40-800 microns. Particles of such material are introduced into raw rubber compounds, replacing part of the rubber. The properties of such rubbers remain at the level of the original products, but the cost price decreases. The resulting active powder complies with GOST R 55419 - 2013.

One of the ways to increase the production efficiency of rubber goods, improve the environmental friendliness of production, and reduce the cost of production is the use of active matrix additives with a special structure.

In the process of processing rubber products, rubber powder is obtained - a set of crushed rubber particles of different dispersion and various shapes, which are characterized by the fact that they basically retain the molecular structure and elastomeric properties of the original rubber.

The most acceptable method for producing active powder is the method of high-temperature shear grinding.

The uniqueness of the active matrix additive lies in the fact that particles of discrete-devulcanized rubber, introduced into raw rubber compounds of the same chemical composition, play the role of vulcanization agents. The strength and deformability of such composite rubbers in a number of cases exceeds the strength and deformability of primary rubbers, and also reduce the cost of final products if the powder content is 3-20 wt%.

The method of high-temperature shear grinding makes it possible to obtain unique particles of active matrix powder with a size of 40-800 microns. Each such particle consists of a plurality of rubber microblocks surrounded by a layer of devulcanized or partially devulcanized material.

The technology implemented in the company's installations makes it possible to obtain cost-effective active rubber powders in one production cycle.

The resulting active rubber powder, corresponding to GOST R 55419 - 2013, is widely used in various fields:

1. in the manufacture of rubber products as a partial replacement of the main component;
2. in some cases, as an active additive in rubber compounds to improve adhesion and wear resistance;
3. as a modifier of asphalt concrete mixtures in road construction;
4. in the manufacture of rubber-bitumen mastics, roofing materials, composite materials.
