Abstract
The invention discloses a kind of high collapsibility water-glass sand, it is made up of the raw material of following parts by weight：100 parts of fresh sand, 48 parts of modified water glass, 23 parts of polyvinyl alcohol, 12 parts of malt syrup, 0.5 1.5 parts of sodium tripolyphosphate, 24 parts of bauxite, 23 parts of lithium ground-slag, 12 parts of borax, 1.5 2.5 parts of blast furnace slag, 0.5 1 parts of rapeseed oil, 0.5 1 parts of sodium acid carbonate, 36 parts of water.The advantage of the invention is that：Sodium silicate sand collapsibility of the present invention is good, peeling labor intensity can significantly be mitigated, save cleaning up cost, and intensity is high, good fluidity, casting accuracy degree is high, surface smoothness is high, and solving casting has the problems such as crackle, glossiness are low, stomata is more, casting quality is greatly improved, reduces percent defective.
Description
Technical field
The present invention relates to glass sand technical field, more particularly to a kind of high collapsibility water-glass sand.
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
The shortcomings of sand advantage is a lot, but poor there is collapsibility, and peeling is extremely difficult.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of high collapsibility waterglass that can mitigate cleaning labor intensity
Sand.
In order to solve the above technical problems, the technical scheme is that：A kind of high collapsibility water-glass sand, its innovative point exist
In：It is made up of the raw material of following parts by weight：100 parts of fresh sand, modified water glass 4-8 parts, polyvinyl alcohol 2-3 parts, malt syrup 1-2
Part, sodium tripolyphosphate 0.5-1.5 parts, bauxite 2-4 parts, lithium ground-slag 2-3 parts, borax 1-2 parts, blast furnace slag 1.5-2.5 parts, vegetable seed
Oily 0.5-1 parts, sodium acid carbonate 0.5-1 parts, water 3-6 parts.
Further, 100 parts of fresh sand, 6 parts of modified water glass, 2.5 parts of polyvinyl alcohol, 1.5 parts of malt syrup, tripolyphosphate
1 part of sodium, 3 parts of bauxite, 2.5 parts of lithium ground-slag, 1.5 parts of borax, 2 parts of blast furnace slag, 0.8 part of rapeseed oil, 0.7 part of sodium acid carbonate, water 4
Part.
The advantage of the invention is that：Sodium silicate sand collapsibility of the present invention is good, can significantly mitigate peeling labor intensity,
Cleaning up cost is saved, and intensity is high, good fluidity, casting accuracy degree is high, surface smoothness is high, and solving casting has crackle, light
The problems such as damp degree is low, stomata is more, greatly improve casting quality, reduce percent defective.
