Abstract
A kind of fast poly-fast precoated sand, precoated sand entirety is spherical or elliposoidal, comprise spherical quartz sand core, the peripheral coated one deck silicone layer of described quartz sand core, the peripheral coated one deck resin bed of described silicone layer, the peripheral coated one deck yellow phosphorus layer of resin bed, the diameter of wherein said quartz sand core is 0.5-1 millimeter, and the thickness of described yellow phosphorus layer is 0.1-0.5 micron.
Description
Technical field
The utility model relates to a kind of die apparatus, especially relates to a kind of fast poly-fast precoated sand.
Background technology
Traditional Making mold adopts common river sand, and the model made is more open, and intensity is low, and the utilization rate of sand is lower, and discarded sand, with a large amount of harmful substances, effectively cannot reclaim, cause pollution to environment.Cover molding sand or the core of one deck hard resin at sand grain surface before precoated sand refers to moulding, because its intensity is high, gas forming amount is low, production casting dimension accuracy advantages of higher, get a lot of applications in mechanical manufacturing field in recent years, but existing precoated sand also also exists the slow problem of poly-speed to be needed further to improve.
Utility model content
The purpose of this utility model is to provide a kind of fast poly-fast precoated sand, and efficiently solve existing precoated sand and gather the slow problem of speed, the technical scheme of employing is as follows:
A kind of fast poly-fast precoated sand, precoated sand entirety is spherical or elliposoidal, comprise spherical quartz sand core, the peripheral coated one deck silicone layer of described quartz sand core, the peripheral coated one deck resin bed of described silicone layer, the peripheral coated one deck yellow phosphorus layer of resin bed, the diameter of wherein said quartz sand core is 0.5-1 millimeter, and the thickness of described yellow phosphorus layer is 0.1-0.5 micron.
Further, the thickness of described silicone layer is 20-50 micron, and the thickness of described resin bed is 0.1-0.2 millimeter.
Further, the periphery of described yellow phosphorus layer also coated one deck layer of silica gel.
Further, the thickness of described layer of silica gel is 1-5 micron.
After adopting this structure, in patternmaking process, extrude precoated sand, the yellow phosphorus evolution of heat causes resin bed to be out of shape condensation rapidly, and sand mold can be successful fast.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of fast poly-fast precoated sand.
Detailed description of the invention
A kind of fast poly-fast precoated sand as shown in Figure 1, precoated sand entirety is spherical or elliposoidal, comprise spherical quartz sand core 1, the peripheral coated one deck silicone layer 2 of described quartz sand core 1, the peripheral coated one deck resin bed 3 of described silicone layer 2, the peripheral coated one deck yellow phosphorus layer 4 of resin bed 3, generate heat in extrusion process for sand mold, the layer of silica gel of the periphery of yellow phosphorus layer 4 also coated one deck 1-5 micron, not oxidated for the protection of yellow phosphorus layer 4, the diameter of wherein said quartz sand core 1 is 0.5-1 millimeter, the thickness of described yellow phosphorus layer 4 is 0.1-0.5 micron, the thickness of silicone layer 2 is 20-50 micron, the thickness of described resin bed 3 is 0.1-0.2 millimeter, after adopting this structure, in patternmaking process, precoated sand is extruded, the yellow phosphorus evolution of heat causes resin bed to be out of shape condensation rapidly, sand mold can be successful fast.
The above, be only detailed description of the invention of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in utility model.
