Abstract

The invention provides a preparation method of single-component phosphate-bonded wear-resistant fire-resistant plastic material. The plastic material comprises corundum used as a main raw material, and alumina powder, alundum powder, siliceous dust and boric acid which are used as substrates; wherein solid aluminum phosphate is used as bonding agent, calcium aluminate cement is used as hardening accelerator and the blowing reaction of phosphate is inhibited by inhibitor. Compared with the traditional phosphate-bonded wear-resistant fire-resistant plastic material, the single-component phosphate-bonded wear-resistant fire-resistant plastic prepared by the invention has the following advantages: 1. ageing mixture is not needed and the production technology is simple; 2. barreled liquid matched phosphate is not needed while driver which is mixed evenly is used when sending the goods; 3. construction is simple which can be only completed by adding water in a certain mix proportion; 4. theplastic material has high intensity, long duration, good wear-resisting performance, and excellent comprehensive performance.

Description

一种单组分磷酸盐结合耐磨耐火可塑料的制备方法 One-component phosphate-binding method of preparing a wear-resistant plastic refractory

[0001] 所属技术领域 [0001] skilled in the art

[0002] 本发明涉及到耐火可塑料的制备方法,具体地讲,涉及到一种单组分磷酸盐结合耐磨耐火可塑料的制备方法。 [0002] The present invention relates to a method for preparing fire-resistant plastic, in particular, it relates to a method for preparing one-component phosphate binding of wear resistant plastic refractory.

背景技术 Background technique

[0003] 石化行业重油催化裂化装置内存在流态化固体催化剂的高速冲刷,所以必须采用耐火材料在金属器壁内作耐磨和隔热衬里。 [0003] The petrochemical industry in high speed memory FCCU flush fluidized solid catalyst, it must be wear-resistant and insulating refractory lining within the metal wall. 石化行业自20世纪60年代建设第一套重油催化裂化装置以来,在很长一段时间,一直使用磷酸盐结合耐磨耐火可塑料作为该装置中的旋风分离器介质磨蚀严重部位的衬里材料。 Petrochemical industry since the 1960s construction of a heavy oil catalytic cracking unit, in a long time, been using phosphate-binding wear fire-resistant plastic can be used as lining material in the device cyclone medium abrasive serious parts. 传统磷酸盐结合耐磨耐火可塑料发货时为双组分。 Traditional phosphate bonded refractory wear when the can is a two-component plastic shipping. 由于磷酸盐结合耐磨耐火可塑料必须在施工前完成困料,否则出现鼓涨现象,会严重影响其施工和使用性能。 Since the phosphate-binding wear fire-resistant plastic material trapped must be completed before construction, otherwise Guzhang phenomenon occurs, it will seriously affect their construction and performance. 为了保证磷酸盐结合耐磨耐火可塑料在施工时具有良好的可塑性, 磷酸盐通常分两步加入:第一步加入部分磷酸盐进行困料;第二步加入余下的磷酸盐,第二步通常在施工搅拌时完成。 In order to ensure wear resistant plastic refractory phosphate binding have good plasticity in the construction, typically phosphate was added in two steps: a first step phosphate is added portion for trapped material; a second step add the remaining phosphate, generally the second step when construction is completed in stir. 这就造成传统磷酸盐结合耐磨耐火可塑料发货时为经过困料的湿料,并另外配以桶装液体磷酸盐,施工搅拌时二者在强制式搅拌机中混合;或困料时一次性将磷酸盐全部加入到部分原料中成为湿料,将可塑料当中不需要困料的部分制成干预混合料,耐火可塑料发货时为干料和湿料两种,施工搅拌时二者在强制式搅拌机中混合。 This causes wear traditional phosphate bonded refractory material is trapped through the wet material, and supported by additional phosphate bottled liquid, stirred mixture of both the construction in a forced mixer when the plastic may be shipped; or when the trapped material once all of phosphate was added to the portion of the feedstock material becomes wet, the portions need not be trapped among the plastic material mixture is made to intervene, two kinds of wet material and dry material both during construction stirred refractory plastic is shipped, mixed in a forced mixer. 这种传统双组分磷酸盐结合耐火可塑料耐磨性能较好,但存在如下缺点:1.保存周期短,长时间存放后,容易结块,丧失施工性能;2.由于可塑料包括湿料和液体磷酸盐两部分,液体磷酸盐运输不方便;3.现场干、湿料搅拌,质量难以控制,对性能影响较大。 This traditional phosphate bonded refractory bicomponent plastic may be better wear resistance, but has the following disadvantages: a short shelf period, after prolonged storage, easy to agglomerate, the loss of workability; 2 since the plastic materials include wet. phosphate and two parts of the liquid, the liquid transportation is not convenient phosphate; 3 site dry and wet material mixing, difficult to control the quality, a greater impact on performance.
