Description
Technical field
The invention belongs to the metal liquid field shaping technique, be specifically related to a kind of Pyrophillite lost foam casting coating, the invention still further relates to the preparation method of this cast paint.
Background technology
Lost foam casting is described as " green foundry engieering " and " foundry engieering of 21 century " with its unique advantage.From the sixties in last century since China begins to use, through the continuous development of decades, the application of lost foam casting constantly enlarges, and has obtained good economic benefit and social benefit.
In lost foam casting, coating is one of key technology.Different with ordinary sand casting, the coating of lost foam casting is coated with to hang over the foam mould surface rather than be coated with and hangs on casting mold or the core.Different in view of lost foam casting and ordinary sand casting, lost foam casting coating is except the instructions for use that should possess conventional cast coating, also to play a role in the following areas, promptly improve the rigidity and the intensity of foam plastics mould, keep the apperance size stability; The stability of dry sand casting mold when keeping cast; Also to when moulding, protect the surface of apperance not to be subjected to washing away of quicksand.Require lost foam casting coating to have high intensity, highly-breathable, good extension property and the thixotropy of being coated with for this reason, also should be convenient to cleaning simultaneously, cost is low, and is easy and simple to handle.
Lost foam casting coating mainly is made up of refractory powder, bonding agent, solvent, suspending agent and special additives.Refractory powder is the important component of coating, and its character has determined the character of coating.Cast paint will be considered many character when selecting refractory powder, as chemical stability under refractoriness, thermal coefficient of expansion, the high temperature and raw material source, price with to the influence degree of people and environment etc.Refractory material commonly used has graphite powder, silica flour, zirconium English powder, schmigel, aluminium vanadine powder, magnesia powder and their mixed powder.
Graphite has very high fire resistance and heat endurance, and the source is abundant, and is cheap, is refractory powder the most frequently used in the sand mold iron casting coating in the past therefore always.Fine and smooth but graphite powder is black, big to human body and environmental pollution, do not meet environmental requirement, replaced by other refractory powder gradually.The silica flour wide material sources, with low cost, certain refractoriness is arranged, in coating, use wider.The subject matter of silica flour is that its dust makes the people suffer from anthraco-silicosis easily, has a strong impact on operating personnel's physical and mental health, does not therefore advocate use.Zirconium English powder has very high fire resistance and thermal conductivity, and thermal expansion is little, and Heat stability is good not with the iron oxide chemically reactive, is mainly used on large-scale steel-casting and the important foundry goods.Zirconium English powder fire resistance is good, but a large amount of dependence on import holds at high price, and the coating cost is very high; In addition, the association breeze of zirconium English powder has radioactivity.Schmigel is good refractory material, but shortage of resources costs an arm and a leg, and is unfavorable for promoting the use of.The magnesia powder thermal expansion is little, and alkali resistance slag ability is strong, but price is more expensive than silica flour.The thermal expansion of aluminium vanadine grog refractory powder is little, refractoriness is high, but cost is than silica flour height.Therefore improve casting quality, developing new refractory powder and cast paint is the task of top priority.
Pyrophillite is the famous nonmetallic minerals of China, and resource is abundant relatively.Pyrophyllite mainly is made up of quartz, kaolin, sericite, and the pyrophyllite based on kaolin or sericite is also arranged.Pyrophillite is a crystal structure, belongs to layer silicate mineral, monoclinic system, and the crystal structure height is unordered.Its chemical structural formula is Al

3, refractoriness〉and 1700 ℃.Pyrophillite has chemical stability, low heat expansion, low heat conductivity, low electric conductivity, high-insulativity, high-melting-point, good a lot of characteristics such as corrosion resistance, thereby makes it be widely used in industrial departments such as pottery, metallurgy, building materials, chemical industry, light industry.Be mainly used in refractory material, ceramic raw material, handicraft and ornament materials, be used for the artificial diamond industrial, glass fibre, filler and candy batching etc.Wherein in the application facet, what external consumption was maximum is to produce refractory material.Make refractory wass, fireproof coating, refractory concrete aggregate as pyrophyllite and clay.
How in the form of sheets the pyrophyllite powder particle, unit weight is less, flowability is better, adsorptivity is medium, hygroscopicity is less, dispersed, wetability is general, suspension better reaches features such as slant acidity, can satisfy color, covering power, enhancing and the suspension requirement of coating to filler.Pyrophillite can be used in paint industry paint filler, papermaking paint, printing ink paint, heat insulating coating, refractory coating and the building coating.People such as the Hu Qinghua of HeFei University of Technology have carried out pyrophyllite powder Study on application in interior wall coating.Coating consists of filler, water and auxiliary agents such as polyvinyl alcohol, waterglass, pyrophyllite powder.The result shows that pyrophillite interior wall coating quality index obviously is better than 106 coating, and pyrophyllite powder has replaced fillers such as part titanium dioxide, lithopone, talcum powder and precipitated calcium carbonate.Pyrophyllite powder is desirable paint filler, can serve as effect (Hu Qinghua, pyrophyllite powder physicochemical property and application study, Anhui geology, 1996,6 (1): 52-56) of part color.It is reported, the covering or the inserts that pyrophyllite powder are used for paint abroad, can make coating have good suspension, durability and viscosity, avoid the wearing and tearing and the (Li Bowei that comes off, the culture river, summarize the development and use of domestic and international pyrophillite and talcum with at industrial quality requirement, Sichuan building materials institute journal, 1988,3 (2): 47-68; Xu Fenglin, Xu Chuanyun. Zhejiang Province's pyrophyllite development and use developing direction, Chinese non-metallic mineral industry guide, 2007, (5): 15-17).Japan uses pyrophyllite powder as papermaking filler, report simultaneously and point out that pyrophyllite powder also is a papermaking paint preferably.Studies show that, utilize that pyrophyllite mineral material has intensity height after low thermal conductivity factor, the roasting, density is little and character such as structure multilayer, can be applied in the heat-insulating material.After in the composite material that carbonaceous material, pyrophyllite mineral material and mica mineral material are formed, adding entry and other adhesives, can form good heat insulating coating through shaping and roasting.
Also there is the bibliographical information pyrophyllite powder in coatings industry, can produce various corrosion-and high-temp-resistant coating and metallurgical casting sapecial coating (Yao Wenjun, Zhang Peiping, Li Shufa, Ma Liyan, the Suker. pyrophyllite mineral products resource and research for application and development present situation thereof, world's geology, 2007,26 (1): 124-129; Liu Ping. brief talk the development and utilization situation of pyrophillite, IM﹠amp; P chemical industry mineral and processing, 2004, (12): 38), but only in relevant document, mention not having detailed data to look into, more do not have concrete coating formula and preparation technology's introduction.
