Embodiment 1

[0021] The present invention proposes a method for preparing waste tire powder with super high reactivity, comprising the following steps:

[0022] S1: Import the waste tire rubber powder, phenolic resin and propyl acetate into the reaction kettle with stirring function, start the stirring mechanism, so that the waste tire rubber powder, phenolic resin and propyl acetate are evenly mixed, and at the same time raise the temperature during the stirring process. High temperature inside the reactor, the temperature is adjusted to 110°C, after stirring for 25 minutes, heat preservation treatment is carried out, so that the internal substances can fully react, the heat preservation time is 1 hour, after the heat preservation is completed, add active zinc oxide, active zinc oxide To improve the activity of the waste tire rubber powder, stir again for 20 minutes, and then keep warm for 1 hour after stirring;

[0023] S2: After the heat preservation is over, add an activator and a disp...

Abstract

The invention discloses a preparation method for a waste tire powder with ultrahigh reaction activity. The preparation method comprises the following steps: introducing waste tire rubber powder, phenol resin and propyl acetate into a reaction kettle with a stirring function, starting a stirring mechanism, raising a temperature in the reaction kettle in the process of stirring at the same time, adjusting the temperature to 110 to 140 DEG C, carrying out stirring for 25 to 40 minutes, then carrying out heat-preserving treatment for 1 to 4 hours, after completion of heat-preserving treatment, adding active zinc oxide, carrying out stirring again for 20 to 50 minutes, after completion of stirring, carrying out heat-preserving for the second time for 1 to 2 hours, after completion of heat-preserving treatment, adding an activator and a dispersant into the reaction kettle in proportion, starting the stirring mechanism, carrying out stirring for 20 to 40 minutes, carrying out pressure-reduceddehydration so as to obtain modified waste tire powder, introducing the modified waste tire powder into a drying device for drying treatment, introducing dried waste tire powder together with a curing agent into a crushing machine, and carrying out crushing.

Description

technical field [0001] The invention relates to the technical field of waste tire rubber powder preparation, in particular to a preparation method of super-high reactivity waste tire powder. Background technique [0002] my country has become a big country in the production and consumption of rubber products in the world. The generation of waste rubber is increasing day by day. If it is not fully utilized, it will not only cause serious environmental pollution, but also waste resources. At present, domestic waste rubber is mainly used to produce reclaimed rubber, but Due to the shortcomings of low profit, high labor intensity, long production process, high energy consumption and serious environmental pollution in the reclaimed rubber industry, many reclaimed rubber factories with traditional crafts in the United States and Europe have closed down one after another, and many domestic reclaimed rubber factories are also looking for another way out. The main way to use waste rub...
