Description
Technical field
The utility model relates to a kind of rubber modified asphalt device, specifically the rubber modified asphalt colloid mill.
Background technology
Modified pitch is meant and added resin, high molecular polymer, levigate modifier such as rubber powder, or adopts pitch is carried out mild oxidation processing, thereby makes the performance improved asphalt mixture of pitch.There are favorable durability, wear resistence in the road surface of laying with its, has avoided the be full of cracks of bituminous paving and aging, has improved service life.
Utilize waste Crumb rubber to replace materials such as resin, high molecular polymer to be spiked into and produce modified pitch in the pitch as modifier, both solved the pollution of junked tire and waste plastics to environment, greatly reduce the production cost of modified pitch again, so rubber modified asphalt has obtained at home and abroad using widely.
In the process of preparation rubber modified asphalt, at first need rubber powder and pitch to be mixed, and form mixture by stirring proportioner; Afterwards said mixture is delivered to colloid mill, utilizes the static cutting disk be arranged on the colloid mill and the mating reaction between the movable grinding disc, realize strong extruding and high speed shear, make the rubber powder refinement and be dispersed in the pitch rubber powder and asphalt mixture.
In the prior art, Chinese patent CN2860613Y discloses a kind of high speed shear colloid mill, described high speed shear colloid mill is provided with charging aperture and discharging opening in the mill body, in the mill body, be provided with the static cutting disk and the movable grinding disc of corresponding matching, static cutting disk is connected with protecgulum, movable grinding disc is fixed on the main shaft, and static cutting disk is divided into elementary roll flute face, intermediate roll flute face, senior roll flute face with the corresponding roll flute face of movable grinding disc; By above-mentioned elementary, intermediate and senior roll flute face is set on static cutting disk and movable grinding disc, guaranteed that described high speed shear colloid mill can make polymeric asphalt modifiers obtain shearing and milling between the roll flute of the multistage flour milling of static cutting disk and movable grinding disc and slot grinding, high temperature viscosity, low-temperature ductility and the elasticity of finished product asphaltum have been improved effectively, improve anti-aging and adhesiveness, and reach the due fineness and the uniformity.But, in the prior art, because the angle of its elementary roll flute face, intermediate roll flute face, the described three grades of roll flute faces of senior roll flute face and horizontal plane is set to different angles, make the rubber asphalt mixture in through the process of shearing, its shear path is horizontal by non-perpendicular setting, be subjected to centrifugal force upwards when causing the rubber asphalt mixture and point to the resistance of roll flute Way in, the speed when having slowed down the rubber asphalt mixture by above-mentioned shear path by the above-mentioned shear path between static cutting disk and the movable grinding disc.When this speed is slowed down, the speed that the rubber asphalt mixture enters colloid mill but is constant, so above-mentioned a large amount of mixtures just are trapped between the inlet even static cutting disk and movable grinding disc of static cutting disk and movable grinding disc, thereby cause on the one hand the colloid mill can't operate as normal easily; On the other hand, in the time of between the rubber asphalt mixture is normally by static cutting disk and movable grinding disc, rubber is evenly distributed in the matrix pitch and rubber grain is of moderate size, and when the rubber asphalt mixture is trapped between static cutting disk and the movable grinding disc, static cutting disk and movable grinding disc are detained part to the rubber asphalt mixture and mill repeatedly, so that the rubber grain in the rubber modified asphalt is too little, is difficult for forming uniform network structure, thereby influences the combination property of rubber modified asphalt.
