Description
技术领域 technical field
本发明一种铸造造型用辅助材料，具体涉及一种用于砂型铸造的醇基干粉铸型涂料。 The invention relates to an auxiliary material for casting molding, in particular to an alcohol-based dry powder casting coating for sand casting.
背景技术 Background technique
在铸造砂型（芯）工作表面上涂覆一层铸造涂料，可以有效防止和减少逐渐表面粘砂，夹砂、砂眼等缺陷，降低铸件表面粗糙度。铸造涂料的质量是影响铸件是否粘砂、夹砂及铸件表面光洁度、铸件尺寸精度的最直接因素。铸造涂料种类繁多，大体可以分为两类：水基涂料和醇基涂料。其中醇基涂料在涂覆后经点燃既可固化，与各种自硬化砂工艺配合使用，可不需烘干，能缩短生产周期，简化工艺，节约能源，减少烘干设备投资，是被铸造界广为使用的一种快干涂料，已广泛应用于钢、铁、有色铸件的生产中。但醇基涂料的载体主要为甲醇、乙醇或异丙醇等组成，属于易燃危险品，在包装、运输、贮存等方面受到诸多约束；此外由于醇基涂料的悬浮稳定性较差，涂料在长途运输和存放过程中易分层，使其性能下降，严重的还可能使涂料出现板结而报废。而采用醇基干粉涂料，由于不含易燃溶剂，使用时只需在干粉中加入醇类溶剂搅拌均匀后既可；干粉涂料包装、贮存方便，运输周期短，费用低。 Coating a layer of casting paint on the working surface of the casting sand mold (core) can effectively prevent and reduce the gradual surface sticking of sand, sand inclusions, sand holes and other defects, and reduce the surface roughness of the casting. The quality of casting coating is the most direct factor that affects whether the casting is sand-sticking, sand inclusion, surface finish of the casting, and dimensional accuracy of the casting. There are many kinds of casting coatings, which can be roughly divided into two categories: water-based coatings and alcohol-based coatings. Among them, the alcohol-based coating can be cured after being coated and ignited. It can be used in conjunction with various self-hardening sand processes without drying, which can shorten the production cycle, simplify the process, save energy, and reduce the investment in drying equipment. It is widely used in the foundry industry. A widely used quick-drying coating has been widely used in the production of steel, iron and non-ferrous castings. However, the carrier of alcohol-based coatings is mainly composed of methanol, ethanol or isopropanol, etc., which are flammable and dangerous goods, and are subject to many constraints in terms of packaging, transportation, and storage; in addition, due to the poor suspension stability of alcohol-based coatings, coatings in It is easy to delaminate during long-distance transportation and storage, which reduces its performance. In severe cases, it may cause the coating to harden and be scrapped. The use of alcohol-based dry powder coatings does not contain flammable solvents, so you only need to add alcohol solvents to the dry powder and stir evenly; the dry powder coatings are easy to pack and store, with short transportation cycles and low costs.
中国专利（申请号：86105456）公开了一种锂基膨润土锆英粉粉状铸型涂料，将锂基膨润土、锆石英粉、树脂和钛白粉等原料通过混合碾磨制成粉状涂料，使用时直接加入乙醇稀释成浆状涂料，但由于锂基膨润土未经引发溶胀，涂料的悬浮性差。中国专利（申请号：200910189788.4）公开了一种醇基纳米复合及表面改性干粉铸型涂料的制备方法，通过采用纳米层状粘土与纳米SiO2组成复合悬浮剂，再与耐火粉料、粘结剂及其他助剂混碾成醇基干粉涂料，其制备工艺要求很高，控制稍有不当即会影响涂料的性能。中国专利（公开号：CN100377811C）公开了一种醇基凹凸棒铸造涂料粉剂的生产方法，以钠化改性的凹凸棒石粘土作为悬浮剂，所制涂料粉剂在乙醇中可以达到较高的悬浮率，但该涂料粉剂中改性凹凸棒粘土所占百分比为55~85%，耐火粉料仅为10~45%，悬浮剂的用量大大高于耐火粉料，虽然得到的涂料有较好的悬浮稳定性，但是以降低涂料的耐火度作为代价的。因此限制了涂料的使用范围，不能用于铸钢件及大型铸铁件的生产。 Chinese patent (application number: 86105456) discloses a lithium-based bentonite zircon powder powder casting coating, the raw materials such as lithium-based bentonite, zirconium quartz powder, resin and titanium dioxide are mixed and milled to make a powder coating. When directly adding ethanol to dilute it into a slurry paint, but because the lithium-based bentonite has not caused swelling, the suspension of the paint is poor. Chinese patent (application number: 200910189788.4) discloses a preparation method of alcohol-based nano-composite and surface-modified dry powder casting coatings, by using nano- layered clay and nano-SiO Binder and other additives are mixed and rolled into alcohol-based dry powder coatings. The preparation process is very demanding, and a slight improper control will affect the performance of the coating. Chinese patent (publication number: CN100377811C) discloses a production method of alcohol-based attapulgite casting coating powder, using sodium-modified attapulgite clay as a suspending agent, and the prepared coating powder can achieve a higher suspension in ethanol rate, but the percentage of modified attapulgite clay in the coating powder is 55~85%, the refractory powder is only 10~45%, the amount of suspending agent is much higher than that of refractory powder, although the obtained coating has better Suspension stability, but at the expense of reducing the refractoriness of the coating. Therefore limit the scope of use of coatings, can not be used for the production of steel castings and large iron castings.
