Abstract
The invention discloses an integrated resin sand mold and its preparation method, which belongs to the sand mold apparatus technical field. The sand mold comprises the following components by weight part: 98-98.4 parts of quartz sand, 1.3-1.5 parts of furan resin, and 0.3-0.5 parts of hardening agent. The method comprises the following steps: mixing the prepared quartz sand, furan resin and the hardening agent according to the corresponding proportion, dumping in a mold for standing and moulding to obtain the products, the integrated resin sand mold is used for casting and producing electrofused zirconia corundum bricks. The integrated resin sand mold has the beneficial effects that the integrity of the sand mold is strong, the size deformation is small, the preparation cost is low and the permeability is good, the preparation method is convenient for discharging the air in the sand mold when a casting process is carried out, thereby the size deformation of the electrofused zirconia corundum bricks is small, the inner part of the bricks enables high density, the porosity is low, the qualified rate of the products is high, the size and the internal quality of the bricks are better than that of a sodium silicate sand mold; the position which requires grinding of the produced blank bricks is minimized, the processing cost is reduced, the product cost is reduced, the economic benefit is raised, and the preparation method operation is simple, so that the integrated resin sand mold enables large batch production.
Description
Technical field
The present invention relates to a kind of whole resin bonded sand mould and preparation method thereof, belong to sand mold device technique field.
Background technology
Mostly the used sand mold of present domestic Corhart Zac-block manufacturer is knockdown water glass sand mold, when using this kind sand mold casting, is prone to cause big, the not high shortcoming of interior solid degree of brick body deformability, and product percent of pass is low.In addition, be the blank brick to the qualified Corhart Zac-block of cast molding, also need carry out attrition process; After treating that the surface reaches certain smooth finish, just can consign to the client, the blank brick material that adopts the water glass sand mold to produce; Because the physical dimension distortion is big; Need the position attrition process amount of processing also big, increased the attrition process expense, manufacturing cost is high.
Summary of the invention
Problem to above-mentioned prior art existence; The present invention provides a kind of whole resin bonded sand mould and preparation method thereof, uses the brick body interior solid degree of this kind sand mold casting high, void content is low, distortion is little, product percent of pass is high, few, the low cost of manufacture of attrition process amount.
To achieve these goals, the technical scheme that the present invention adopts is: a kind of whole resin bonded sand mould, and it fills a prescription by weight that proportioning is: silica sand 98-98.4 part; Furane resin 1.3-1.5 part; Stiffening agent 0.3-0.5 part.
Silica sand adopts be dioxide-containing silica greater than 98.5%, granularity is a 40-70 purpose silica sand.
The preparing method's of this integral body resin bonded sand mould manufacture craft is: select materials → mix → moulding; Select silica sand, furane resin and stiffening agent; Again silica sand, furane resin and stiffening agent are added in the mixing tank in said ratio, stir, grind evenly, subsequent use; At last subsequent use compound is poured in the model, at normal temperatures, left standstill moulding, seasoning.
If under the situation of producing urgent need, also can be by microwave dryer with mold drying.
The invention has the beneficial effects as follows: this kind sand mold globality is strong; Thereby size distortion is little, and permeability is good, and the gas when being convenient to build in the sand mold is discharged; Corhart Zac-block body profile size distortion with after its casting is little; Brick body interior solid degree is high, void content is low, and product percent of pass is high, and brick material physical dimension and inner quality all are superior to the water glass sand mold.For the blank brick material that adopts this kind sand mold to produce, because the physical dimension distortion is little, need the position attrition process amount of processing greatly to reduce, greatly reduced the attrition process expense, thereby the whole cost that has reduced product has improved economic benefit.The preparation method is simple to operate, and manufacturing can be mass-produced.
