Self-repairing wear-resistant plastic refractory for converter lining and preparation method of self-repairing wear-resistant plastic refractory
The invention discloses a self-repairing wear-resistant plastic refractory for a converter lining. The self-repairing wear-resistant plastic refractory comprises the following raw materials in percentage by mass: 20-30% of dolomite sand, 25-35% of fused magnesia, 5-10% of silicon carbide micro powder, 10-15% of a binding agent, 1-3% of a plasticizer, 2-5% of a self-repairing agent and the balance of sintered magnesia, wherein the self-repairing agent comprises the following components in parts by mass: 20-30 parts of magnesite clinker, 1-5 parts of sodium hexametaphosphate, 1-5 parts of tung oil, 1-10 parts of phenolic resin, 1-3 parts of melamine and 6-8 parts of ethanol; the preparation method of the plastic refractory comprises the following steps: S1, ball milling and screening; s2, heat treatment; s3, mixing; according to the plastic refractory disclosed by the invention, several main materials are subjected to grading treatment according to particle sizes, so that the obtained plastic refractory not only has excellent wear resistance, but also has a self-repairing function when cracks appear by adding the self-repairing agent, and the performance of the plastic refractory is further improved.
本发明公开了一种转炉内衬用的自修复耐磨可塑料，按质量百分比计包括以下原料：20～30％白云石砂、25～35％电熔镁砂、5～10％碳化硅微粉、10～15％的结合剂、1～3％增塑剂、2～5％自修复剂以及余量的烧结镁砂；其中，所述自修复剂按质量份数计包括：20～30份烧结镁砂、1～5份六偏磷酸钠、1～5份桐油、1～10份酚醛树脂、1～3份三聚氰胺以及6～8份乙醇；上述可塑料的制备方法包括以下步骤：S1、球磨筛分；S2、热处理；S3、混合；本发明的可塑料通过对几种主料按粒径进行分级处理，使得到的可塑料不仅具有优良的耐磨性，且通过加入自修复剂而实现在出现裂痕时具有自修复功能，进一步提高可塑料的性能。
