Continuous particle surface modification reactor adopting drying method

Abstract

The invention discloses a continuous particle surface modification reactor adopting a drying method. The reactor comprises a cylinder body, atomizers are arranged at the left and right ends of the cylinder body, and a feeding port and a discharging port which are in a straight line are respectively formed in the upper and lower ends of the cylinder body; a first gear and a second gear are arrangedin the cylinder body and are meshed with each other in a meshing reaction area; the meshing reaction area is directly connected with the feeding port and the discharging port; an atomizing chamber isdirectly connected with the first gear and the second gear, and the atomizing chamber, the first gear and the second gear are located in the cylinder body; the inside of the cylinder body is directlyconnected with an arc heating device, the inner wall of the arc heating device directly makes contact with the gears, and the gears and the inner wall are in a sealing state. Compared with a traditional surface modification reactor, according to the continuous particle surface modification reactor, the utilization rate of a surface modification agent is high, the modification effect is good, theoperation is simple, and continuous large-scale production is easy.

Description

technical field [0001] The invention relates to a particle surface modification reactor, in particular to a particle dry continuous surface modification reactor. Background technique [0002] Particle surface modification technology is widely used in rubber, coatings, papermaking, ink and plastics. Because the surface of inorganic particles is hydrophilic and oleophobic, it is easy to agglomerate, and has poor compatibility with organic phases, so it can be combined with organic matter. performance degradation. In order to improve its dispersibility in organic substrates and improve the affinity between inorganic particles and organic substrates, coupling agents, surfactants and unsaturated organic acids are usually used to modify the surface of particles to change the chemical structure of their surfaces. , so that the dispersion of particles in the organic substrate is enhanced, thereby improving the performance of the material. In order to obtain a better modification e...

Problems solved by technology

Surface chemical coating modification has high requirements on the circulation of materials. In addition, the uniformity of modifier dispersion also has a direct impact on the modification effect. If the material circulation is not good or the modifier is not uniformly dispersed, it will cause particles The modification effect becomes worse

[0004] At present, dry surface modification methods include high-speed stirring, high-speed impact surface modification, etc. However, continuous modification in the true sense has not been realized in these methods, and the equipment required is complicated in structure and expensive, resulting in high production costs
