Abstract
The present invention discloses a preparation method for the dry powder of alcoholic paint, which belongs to dry powder for casting moulds. In the preparation method, raw materials are crushed, mixed, milled and modified; resin is added to be solidified, clay soil and urotropine are added to be diluted; finally, the dry powder of alcoholic paint is obtained. The dry power for alcoholic paint has the advantages of no sintering, difficult combustion and explosion, stable chemical properties, low gas yield, high adhesiveness, no precipitation, low cost and simple technology; the dry powder can be used after being diluted by ethanol, and the diluted dry powder is quick to dry and is laborsaving when coated on a casting mould; the dry powder is convenient to transport, store, popularize and apply, and the dry powder can be stored for more than one year.
Description
The invention belongs to a kind of dry powder of alcoholic paint that casting pattern is used.
Used coating adopts traditional paste alcohol-base paint always in foundary industry.Paste coating exists defective at aspects such as refractory temperature, adhesiveness, chemical stability, suspension and gas forming amounts.Not only give transportation, packing, store and brought great inconvenience, and the corresponding casting product quality of producing is low, performance indications are poor, and the defect rate height has influenced the quality of cast product.
The purpose of process for preparation of dry powder of alcoholic paint of the present invention is to design a kind of high temperature resistant, sintering not according to the above-mentioned defective that exists, stable chemical performance, gas forming amount is few, adhesiveness is strong, the process for preparation of dry powder of alcoholic paint that should not precipitate, to adapt to the requirement of high quality casting product, changed former paste coating form, be convenient to packing, transportation, store.Coating dry powder cost is low, technology is simple, is convenient to practical the popularization.
Process for preparation of dry powder of alcoholic paint of the present invention takes following scheme to realize.The prescription of dry powder of alcoholic paint is: (being commonly referred to as bone meal) 88-90% such as silica flour, graphite powder, lithium soil 1.1-1.3%, (SPan) 0.01-0.03% of class of department, 381 resin 2-3%, polyvinyl butyral (PVB) 0.1-0.4%, methenamine 7-8%, clay 1-2%.Process for preparation of dry powder of alcoholic paint be quartz, graphite is broken, sieve, selection by winnowing, fineness 300 orders, mixed grind 15-40 minute; Add then lithium soil after the degenerative treatments (its processing method be by lithium soil than water than ethanol=1: 1: 1, mix and stirred 1.5-3.5 hour) mixed grind 30 minutes; Added 381 resin mixed grinds 20-50 minute; Add and solidify the suspending agent PVB mixed grind of handling 20 minutes (solidifying processing is with the saturated polyvinyl butyral of ethanol, and heating); Added clay, methenamine mixed grind 30-60 minute; Added class of department with the ethanol dilution process (diluted concentration is: ethanol was than class of department=100: 1) at last mixed grind 15-40 minute.Promptly obtain qualified dry powder of alcoholic paint product.
That dry powder of alcoholic paint of the present invention has is high temperature resistant, sintering not, stable chemical performance, gas forming amount is few, adhesiveness is strong, should not precipitate, adapt to the requirement of high quality casting product, change former paste coating form, be convenient to packing, transportation and storage, storage period, extended to more than 1 year by original three months.Product cost of the present invention is low, and technology is simple, and is easy to use, with using after the ethanol dilution, is coated in fast dried saving trouble on the mold type, easy to utilize.
Process for preparation of dry powder of alcoholic paint of the present invention will be further described in conjunction with the accompanying drawings.
Accompanying drawing is a dry powder of alcoholic paint preparation technology flow chart of the present invention.
The 1-broken 2-mixed grind 3-degenerative treatments 4-that feeds intake adds 381 resins
5-solidifies processing 6-and adds clay and methenamine 7-dilution process
8-dry powder of alcoholic paint product.
With reference to accompanying drawing, process for preparation of dry powder of alcoholic paint of the present invention, the fragmentation (1) that earlier quartz, graphite fed intake is sieved, selection by winnowing, fineness 300 orders, mixed grind (2) 15-40 minute; Add then the lithium soil mixed grind 30 minutes after the degenerative treatments (3); Added 381 resins (4) mixed grind 20-50 minute; The suspending agent PVB mixed grind of adding curing processing (5) 20 minutes; Added clay and methenamine (6) mixed grind 30-60 minute; Add at last the mixed grind 15-40 of class of department minute of ethanol dilution process (7), namely obtain qualified dry powder of alcoholic paint (8) product. The fragmentation (1) that feeds intake is that quartz, graphite is broken, sieve, selection by winnowing, fineness 300 orders, degenerative treatments (3) method be by lithium soil than water than ethanol=1: 1: 1, carried out mix and blend 1.5-3.5 hour. Solidifying (5) method of processing is with the saturated PVB of ethanol, and heating. Dilution process (7) concentration is: class of ethanol ratio department=100: 1.
Prescription of the present invention is: silica flour and graphite powder 88-90%, lithium soil 1.1-1.3%, the 0.01-0.03% of class of department, resin 2-3%, PVB0.1-0.4%, methenamine 7-8%, clay 1-2%, key problem in technology of the present invention is preparation method and prescription, process is put upside down, and the operating time is inaccurate, and formulation ratio is incorrect, can both cause that product is defective, caking or paste appear in product.
Embodiments of the invention:
Process for preparation of dry powder of alcoholic paint of the present invention be with aggregate fragmentations such as silica flour, graphite powder sieve, selection by winnowing, fineness 300 orders, mixed grind 15-40 minute; The lithium soil mixed grind 30 minutes that adds degenerative treatments then; Added 381 resin mixed grinds 20-50 minute; The suspending agent PVB mixed grind that adding curing is handled 20-40 minute; Add clay and methenamine mixed grind 30-60 minute, added at last the mixed grind 15-40 of class of department minute that uses the ethanol dilution process, promptly obtain qualified dry powder of alcoholic paint product.Prescription of the present invention as mentioned above.
Dry powder of alcoholic paint of the present invention is applicable to resin sand, closes fat sand and dry type clay sand mold, diluent is ethanol or isopropyl alcohol, and is easy to use, and cost is low, be coated in and do not need secondary drying on the casting mold fuse, do not need compressed air, with short production cycle, the economic benefit height, performance is good, the quality height, not easy to blast, easy to utilize.
