Problems solved by technology

[0002] Because the structure of die castings and metal castings is relatively dense, their mechanical properties are relatively high. Applying chilled coatings on the mold can effectively refine the structure of the castings and improve the quality and mechanical properties of the castings. Due to metal castings and die castings The surface of the workpiece usually needs to be trimmed. In the existing technology, the cost of metal surface processing is relatively high

Embodiment 1

[0007] A packaging coating suitable for aluminum alloys. The raw materials in the formula are composed by weight percentage: 0.5% graphite powder, 10% tin powder, 1% hexamethylbenzene, 1% silane coupling agent, 1% stabilizer, 5% suspending agent, 10% sulfur powder, and 30% binder. At this time, the thermal conductivity is not significantly improved, and the grains of alloy castings cannot be refined enough.

Embodiment 2

[0009] A packaging coating suitable for aluminum alloys. The raw materials in the formula are composed by weight percentage: 6% graphite powder, 35% tin powder, 10% hexamethylbenzene, 3% silane coupling agent, 2.5% stabilizer, 20% suspending agent, 20% sulfur powder, 60% binder, the cooling speed is slow at this time, and the casting surface performance of aluminum alloy castings is insufficient.

Embodiment 3

[0011] A packaging coating suitable for aluminum alloys. The raw materials in the formula are composed by weight percentage: 4% graphite powder, 23% tin powder, 5% hexamethylbenzene, 1.5% silane coupling agent, 1.25% stabilizer, 13% suspending agent, 15% sulfur powder, 45% binder. At this time, the thermal conductivity is improved, the grains of the metal casting are refined, the performance is improved, the cooling speed is increased, and the grains on the surface of the zinc alloy are refined, significantly Increase the thickness of the fine-grained area on the surface to improve the performance of the surface of zinc alloy castings.

Abstract

The invention discloses a packaging coating suitable for an aluminum alloy. The packaging coating comprises an additive and a carrier. Raw materials in the formula comprise, by weight percent, 0.5%-6%of graphite powder, 10%-35% of tin powder, 1%-10% of hexamethylbenzene, 0-3% of a silane coupling agent, 0-2.5% of a stabilizer, 5%-20% of a suspending agent, 10%-20% of sulfur powder and 30%-60% ofa binder. According to a product prepared through the packaging coating, heat conductivity is improved, grains of a metal casting are refined, performance is improved, the cooling speed is increased,grains on the surface of the aluminum alloy are refined, the thickness of a grain area of the surface layer is obviously increased, and the performance of the surface of the aluminum alloy casting isimproved.

Description

technical field [0001] The invention discloses a packaging paint suitable for aluminum alloys. Background technique [0002] Because the structure of die castings and metal castings is relatively dense, their mechanical properties are relatively high. Brushing the chilled coating on the mold can effectively refine the structure of the casting and improve the quality and mechanical properties of the casting. Due to the metal casting and die casting The surface of the workpiece usually needs to be trimmed. In the existing technology, the cost of metal surface processing is relatively high. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a packaging coating suitable for aluminum alloys, which improves the thermal conductivity, refines the crystal grains of metal mold castings, improves the performance, increases the cooling speed, and refines the surface of the aluminum alloy. grains, signifi...
