Abstract
The invention discloses a kind of sodium silicate sand with high wet-compressive strength, is made up of the raw material of following parts by weight：55 75 parts of silica sand, 30 40 parts of diamond dust, 10 15 parts of lime stone, 58 parts of bentonite, 47 parts of modified water glass, 23 parts of gum arabic powder, 12 parts of dioctyl phthalate, 34 parts of graphite powder, 23 parts of talcum powder, 1.5 2.5 parts of gypsum, 12 parts of triisopropanolamine, 0.5 1 parts of stearic acid, 35 parts of water.The advantage of the invention is that：Water-glass sand green compression strength of the present invention is high, easy molding and repairing type, fully meets the technological requirement of first molding after-hardening, and good fluidity, gas forming amount is low, and good permeability, collapsibility are good, can significantly improve casting quality, reduces casting wasted product rate.
Description
Technical field
The present invention relates to glass sand technical field, more particularly to a kind of sodium silicate sand with high wet-compressive strength.
Background technology
Big-and-middle-sized casting is produced in the past and all uses clay-beaded sand, and drying oven drying is sent to after having made type, the production cycle is grown,
Casting accuracy is poor, and working condition is poor, far can not meet the needs of production development.Water-glass sand is because mobility is high, compact rate of molding
Height, hardening is fast, and casting accuracy is high, and source is wider, cheap, it is green the features such as, it has also become develop in recent decades most
One of fast molding sand species.Current most of steel-castings and large-sized iron casting are produced using water virus, although waterglass
Sand advantage is a lot, but there is green compression strength it is low the shortcomings that, certain difficulty is brought to molding and repairing type, can not be met
The technological requirement of first molding after-hardening.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of sodium silicate sand with high wet-compressive strength for being capable of easy molding.
In order to solve the above technical problems, the technical scheme is that：A kind of sodium silicate sand with high wet-compressive strength, its innovative point
It is：It is made up of the raw material of following parts by weight：Silica sand 55-75 parts, diamond dust 30-40 parts, lime stone 10-15 parts, bentonite 5-8
Part, modified water glass 4-7 parts, gum arabic powder 2-3 parts, dioctyl phthalate 1-2 parts, graphite powder 3-4 parts, talcum powder
2-3 parts, gypsum 1.5-2.5 parts, triisopropanolamine 1-2 parts, stearic acid 0.5-1 parts, water 3-5 parts.
Further, 65 parts of silica sand, 35 parts of diamond dust, 12 parts of lime stone, 6 parts of bentonite, 5 parts of modified water glass, I
Primary 2.5 parts of gum powder, 1.5 parts of dioctyl phthalate, 3.5 parts of graphite powder, 2.5 parts of talcum powder, 2 parts of gypsum, three isopropanols
1.5 parts of amine, 0.7 part of stearic acid, 4 parts of water.
The advantage of the invention is that：Water-glass sand green compression strength of the present invention is high, easy molding and repairing type, fully meets and first rises
The technological requirement of mould after-hardening, and good fluidity, gas forming amount is low, and good permeability, collapsibility are good, can significantly improve casting matter
Amount, reduce casting wasted product rate.
