The utility model provides a kind of temperature to mix the process units of modified bitumen for the drawback of prior art.
Temperature described in the utility model is mixed the process units of modified bitumen, comprises stirred tank, comprises that also the charging-tank that gathers materials, pitch charging-tank, EVA micelle charging-tank and temperature mix the modifying agent charging-tank;
Wherein, the discharging opening of the discharging opening of the discharging opening of the described charging-tank that gathers materials, pitch charging-tank, EVA micelle charging-tank and the warm discharging opening of mixing the modifying agent charging-tank are communicated with respectively stirred tank;
Described charging-tank and the pitch charging-tank of gathering materials is respectively arranged with heater.
Temperature described in the utility model is mixed in the process units of modified bitumen, and the heater of the described charging-tank that gathers materials is electric heater; The heater of described pitch charging-tank is electric heater.
Temperature described in the utility model is mixed in the process units of modified bitumen, by increase EVA micelle charging-tank is set, so that can improve the softening point of pitch and the anti-rut of high temperature of compound by adding the EVA micelle in process of production.
Description of drawings
Fig. 1 is the structural representation that temperature described in the utility model is mixed the process units of modified bitumen.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the manual literal to make those skilled in the art.
As shown in Figure 1, temperature described in the utility model is mixed the process units of modified bitumen, comprises stirred tank 5, is provided with mixing plant 51 in the described stirred tank 5.This stirred tank 5 is agent sets of process units described in the utility model, and the mix and blend of each material is all finished by mixing plant 51 in this stirred tank 5.
The process units that temperature described in the utility model is mixed modified bitumen comprises that also the charging-tank 1 that gathers materials, pitch charging-tank 2, EVA micelle charging-tank 3 and temperature mix modifying agent charging-tank 4.Wherein, the described charging-tank 1 that gathers materials is provided with heater 11, and this heater 11 specifically can be electric heater; Described pitch charging-tank 2 also is provided with heater 21, and this heater 21 specifically can be electric heater.The discharging opening 42 that the discharging opening 32 of the discharging opening 12 of the described charging-tank 1 that gathers materials, the discharging opening 22 of pitch charging-tank 2, EVA micelle charging-tank 3 and temperature are mixed modifying agent charging-tank 4 is communicated with respectively stirred tank 5.
Using temperature described in the utility model, to mix the manufacturing process of process units of modified bitumen as follows:
The described charging-tank 1 that gathers materials will gather materials and be preheated to 160 degree, and in discharging opening 12 is put into stirred tank 5.Described gathering materials is comprised of rubble, sand grains and powder.
Described pitch charging-tank 2 is put into asphalt heating to 145 degree in the stirred tank 5 through discharging opening 22 again.
Described EVA micelle charging-tank 3 through its discharging opening 32 to stirred tank 5 interior input EVA (ethylene-vinyl acetate copolymer) micelles, here can select EVA28-150, the adding of described EVA micelle can obviously improve the anti-rut performance of high temperature of softening point and the compound of pitch.
Described temperature is mixed modifying agent charging-tank 4 and is mixed modifying agent through its discharging opening 42 to stirred tank 5 interior input temperature, described temperature is mixed each component ratio of modifying agent: 100 parts in water, 20 parts of sodium alkyl sulfates, 20 parts of palmitic acid, 20 parts of oleic acid, 10 parts of neopelexes, 10 parts of hexadecyltrimethylammonium chlorides, 20 parts of imidazoline type cationic surfactants.
The weight ratio of above-mentionedly gather materials, pitch, EVA micelle, temperature being mixed modifying agent is as follows: gather materials 100 parts, and 5 parts of pitches, temperature is mixed 0.5 part of modifying agent, 0.1 part in EVA micelle.After above-mentioned each material is put in the stirred tank 5, can open stirred tank 5 and stir, mix modified bitumen thereby obtain temperature.
Temperature described in the utility model is mixed in the process units of modified bitumen, by increase EVA micelle charging-tank is set, so that can improve the softening point of pitch and the anti-rut of high temperature of compound by adding the EVA micelle in process of production.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in manual and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
