Problems solved by technology

[0004] Asphalt particles for drilling fluid need to have higher asphalt softening point and smaller particle size, but it is difficult to crush high softening point asphalt into fine particles, and the general crushing method will release a lot of heat during the crushing process. , so that the asphalt particles become soft and bonded due to the increase in temperature, and recombine into large asphalt particles, which greatly affects the actual application effect

Abstract

The invention discloses a high-softening-point asphalt particle. The prepared high-softening-point asphalt particle has a shell-core structure, the outer layer of the asphalt particle is coated with a layer of high polymer with temperature sensitivity, the high polymer can deform along with temperature rise and has a high softening point, and the core layer of the asphalt particle is a modified asphalt mixture and has high mechanical property and hydrophobic capacity. When the shell layer of the asphalt particle is slightly melted, an optimizing liquid in the core layer of the asphalt particle can effectively increase the viscosity of the high polymer of the shell layer of the asphalt particle, the blocking effect of the asphalt particle on microcracks of the well wall is avoided, and the temperature use range of the high-softening-point asphalt particle is effectively expanded. The process is simple, easy to control and convenient to operate, the particle size of asphalt particles is small, the softening point is high, the microcrack blocking effect is good, and the market prospect is large.

Description

technical field [0001] The invention relates to the technical field of asphalt, in particular to a high softening point asphalt granule. Background technique [0002] Asphalt is a polycyclic aromatic hydrocarbon aggregate with a certain viscosity. It is widely used in road paving and house construction because of its excellent water resistance, cohesiveness and corrosion resistance; the softening point of ordinary asphalt is 60-110°C. Uneven curing state is prone to cause coking, which not only affects the use effect of asphalt, but also easily causes the problem that the reactor is difficult to clean, which limits the development of asphalt; high softening point asphalt has high coking value and excellent high temperature resistance , can be widely used in carbon refractory materials, spherical activated carbon, lithium-ion battery negative electrode material coating materials, etc., increasing the softening point of asphalt can effectively broaden the application field of ...
