Abstract
The present invention provides molding sand and a preparation method thereof, which relates to special casting mould facing sand and a preparation method thereof in casting industry. The molding sand is composed of zircon sand, zircon powder of which the zircon sand weight is 0.3 to 0.8%, 0.6 to 1.2% of graphite powder, and 7 to 9% of water glass. The present invention has the preparation method that the zircon sand, the zircon powder and the graphite powder according to the proportion by weight are mixed for 5 to 10s by a kneading mill, and are added with the water glass for being wetly mixed for 15 to 20s so as to obtain the molding sand. The present invention selects the zircon sand as main molding materials to aim at the characteristics of high strength requirements and good fireproof degree requirements. In order to obtain the good quality of a mold surface, the present invention adds the zircon powder as an auxiliary material for regulation. In order to increase sand flowability, improve mold filling capacity, enhance the subtleness of the molding sand, and guarantee fireproof performance, the present invention adds the graphite powder. In order to realize the purposes of simple and convenient preparation, the present invention uses the water glass as cement. In order to realize the purposes of convenient casting molding and stripping, the present invention selects a CO2 hardening mode. The present invention has the advantages of reasonable prescription and preparation method, high sand strength, good surface quality, short production period and high production efficiency, and can improve the quality of an art casting product.
Description
Technical field
The present invention relates to special casting mold facing sand and compound method thereof in a kind of casting industry, the Modeling Material and the compound method thereof of the art casting of particularly higher, surperficial polish more complicated to surperficial quality requirement.
Background technology
Because the particularity of artistic cast article moulding, traditional handicraft adopts the light water glass sand to make casting mold sand more, preparation is easy, with low cost, easy to operate though the light water glass sand has, moulding is easy to advantage, but weak point is arranged also: at first, undercapacity is to make the foundry goods of ultra-large type art casting; Secondly, pay attention to the most for art casting one---surface quality, can not satisfy its outward appearance and be close to perfect harsh requirement.And the foundry goods that utilizes this sand to make, needing a large amount of later stage rest and reorganization work, this greatly reduces the operating efficiency of making art casting, has prolonged the production cycle to a great extent simultaneously, has wasted a large amount of human and material resources.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of prescription, the preparation method is reasonable, the intensity height, surface quality is good, with short production cycle, production efficiency is high, can improve molding sand of artistic cast article quality and preparation method thereof.
The implementation of the object of the invention is that molding sand is made up of the zirconium English powder of zircon sand, zircon sand weight 0.3-0.8%, the graphite powder of 0.6-1.2%, the waterglass of 7-9%.
The preparation method of molding sand, the graphite powder of getting zirconium English powder, the 0.6-1.2% of zircon sand, zircon sand weight 0.3-0.8% mixes 5～10s with puddle mixer, then adds waterglass wet mixing 15 ~ 20s of zircon sand weight 7-9%, molding sand.
The present invention is directed to the characteristics that mould strength requirement height, fire-resistant degree require, select zircon sand as main Modeling Material; For the mo(U)ld face quality is good, adds zirconium English powder and make to regulate auxiliary material; For increasing sand fluidity, improve mold-filling capacity, strengthen the molding sand exquisiteness, and guarantee its fire resistance, add graphite powder; Easy for preparing, easy to operately make binding agent with waterglass; Be moulding and the molding that makes things convenient for foundry goods, select CO
2The sclerosis mode.
Prescription of the present invention, preparation method are reasonable, and the sand bond height, surface quality is good, with short production cycle, production efficiency is high, can improve artistic cast article quality.
The specific embodiment
Molding sand of the present invention is made up of the zirconium English powder of zircon sand, zircon sand weight 0.3-0.8%, the % graphite powder of 0.6-1.2, the waterglass of 7-9%.The preparation method is, takes by weighing zircon sand, zirconium English powder, graphite powder by the percent by weight proportioning and mixes 5～10s with puddle mixer, then adds waterglass wet mixing 15 ~ 20s, molding sand.
At mo(U)ld face quality requirement height, suitable granularity requirements is selected in the requirement that has certain air permeability simultaneously, wherein, select 50-100 purpose zircon sand, 350 purpose zirconium English powder,＞200 purpose graphite powders, modulus are 2.2-2.4, and Baume degrees is 48～50 waterglass.
Adopt two batch (-type) puddle mixers that stir in the present invention's preparation, two groups of three layers of blade agitators of machine, rotating speed is 280r/min, the stirring scope is wide, has fully satisfied quick, the requirement uniformly of mulling.
