Abstract
The invention discloses resin casting molding sand and a preparation method thereof. The method mainly comprises: performing dry mixing of component raw materials including quartz sand, straw ash, tung oil, asbestos, a furan resin, a phenolic resin, kaoline and potassium dichromate by certain weight parts; and adding water, mixing, placing sand after mixing, molding, casting, cooling and separating to obtain a finished product. The preparation method is simple, the formula is reasonable, the cost is low, the production efficiency is high, the surface of the aluminum sand is made smooth by strictly controlling the particle size of the quartz sand, and the breathability is high.
Description
Technical field
The present invention relates to a kind of resin casting sand and preparation method thereof, belong to the foundary industry field.
Background technology
Molding sand is to be used for the material of moulding in sand casting, molding sand is generally mixed according to a certain percentage by casting model powder, moulding sand binder and the auxilliary Modeling Material such as thing that adds, also available natural silica sand argillaceous, the medium-sized sand grains of the sand formulation that common cast aluminium is used footpath is too big or too little, and molding sand material footpath is too big, though gas permeability is better, but aloxite spare surface ratio is more coarse, and fineness is bad, and molding sand material footpath is too little, cause the sand mold gas permeability bad, aluminium casting has pore to produce well.Molding sand can be divided into clay-bonded sand, water-glass sand, cement bonded sand, quartz sand etc. by used binding agent difference, with clay-bonded sand, water-glass sand and quartz sand use at most.
Summary of the invention
In order to alleviate the deficiencies in the prior art and defective, the object of the present invention is to provide a kind of resin casting sand and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:
The resin casting sand is characterized in that the weight portion of its constitutive material is: quartz sand 80-90 part, stalk ashes 5-15 part, tung oil 3-5 part, asbestos 3-5 part, furane resins 3-5 part, phenolic resins 1.2-1.8 part, kaolin 0.5-1.5 part, potassium bichromate 0.05-0.1 part and moisture 2-5 part.
The preparation method of described resin casting sand is characterized in that may further comprise the steps:
(1) quartz sand is crossed 100 mesh sieves, press weight portion mixing quartz sand, stalk ashes, tung oil, asbestos, furane resins, phenolic resins, kaolin and the potassium bichromate of constitutive material then, do earlier and mix 10-20 second, added the water mixing again 1-3 minute, put sand 15-25 second after mixed;
(2) mixture that step (1) is obtained is put into sand storage bin, and moulding, casting cooling 1-1.5 hour separate obtaining finished product.
Beneficial effect of the present invention:
Preparation method of the present invention is simple, fill a prescription reasonable, with low cost, production efficiency is high, by the particle diameter of strictness control quartz sand, make aloxite spare smooth surface, and gas permeability is also fine.
