Abstract

The invention provides a heatproof and wear resistant lining material, and belongs to the field of petrochemical engineering. The heatproof and wear resistant lining material is mainly composed of a base material and additives. The base material comprises 55 to 70% of aggregate, 10 to 15% of powder, and 20 to 30% of bonding agent. The additives comprise a composite additive and explosion-proof fibers. The using amount of explosion-proof fibers is 0.05 to 0.1% of the total weight of lining material. The using amount of composite additive is 0.2 to 0.7% of the weight of base material. The lining material has a high temperature rising speed under baking, the curing time is shortened, and the lining material has the advantages of high early strength, heatproof and wear resistant properties, and strong bonding force.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a heat-insulating and wear-resistant lining material. Background technique [0002] In the process of petrochemical production, oil refining is often carried out by catalytic cracking reaction, and due to the complexity of the reaction, special reaction-regeneration system, fractionation system and absorption-stabilization system are required. Among them, the reaction-regeneration system is the most important part in the catalytic cracking process, and the severe catalytic cracking reaction often causes damage to the reaction-regeneration system. [0003] At present, the overhaul and emergency repair of the reaction-regeneration system often use hydraulic heat-insulating and wear-resistant lining materials. In actual operation, during the construction period, the strength of the lining material must reach 50% to 70% of the concrete strength before the corresponding bottom f...
