Embodiment Construction

[0005] Get 65 kilograms of soap making leftovers in the production soap of soap factory, 15 kilograms of rosin, 10 kilograms of auxiliary decomposers, 5 kilograms of calcium carbonate, 5 kilograms of odorless pine tar. After the above composition is fully stirred and dissolved, 100 kg of decomposing agent is obtained, and 200 kg of crushed waste rubber particles (with a particle size below 40 mesh) are taken and put into a stainless steel barrel, and the above decomposing agent is slowly poured into the stainless steel bucket. Fully stir in the barrel, the soap-making leftovers in the decomposing agent contain grease, and at the same time, under the action of other components, the waste rubber particles slowly decompose and become plastic, and then pressurize 17 kg and heat to 220 degrees Celsius. 3 hours of dynamic desulfurization, release residual gas, mechanical desulfurization, take out the raw materials and put them on the tablet press to make thin sheets of regenerated ru...

Abstract

The invention relates to a decomposition agent for the production of reclaimed rubber through decomposition method, which comprises (by weigh portion) soap stock 60-65%, rosin 15-20%, accelerating agent 5-10%, calcium carbonate 2-5%, pine tar 2-5%.

Description

technical field [0001] The invention relates to a decomposer for producing odorless regenerated rubber by decomposition method. Background technique [0002] At present, in order to make full use of waste rubber, there are many ways to deal with the regeneration of waste rubber, but ordinary regenerated rubber is usually processed mechanically and chemically under heat and pressure conditions to make the vulcanized rubber reticular. The cross-linked structure is degraded and has plasticity, and becomes regenerated rubber for re-vulcanization processing. However, in the production process, there are high energy consumption and complicated process. At the same time, a large amount of waste water, waste gas and harmful substances will be generated, which will greatly pollute the environment. Recently, the recycling of waste rubber by decomposition method has appeared. Although the shortcomings of the above-mentioned processing methods have been improved, the regenerated rubber ...
