Abstract

The invention discloses a high-performance environment-friendly aluminum alloy mould release agent which consists of modified organic silicone, grease synthetic ester, anti-rust inhibitor, preservative, surfactant and water. The high-performance environment-friendly aluminum alloy mould release agent adopts the special modified organic silicone and the grease as the composite lubricating mould release agent and is further provided with a variety of the anti-rust inhibitor, the preservative and the surfactant, and the product has excellent heat resistance performance and can greatly improve the high-temperature stability and the high-temperature mould release performance of the product and greatly reduce the occurrence of air holes.

Description

Technical field: [0001] The invention relates to an aluminum alloy release agent. Background technique: [0002] After the 1990s, China's die-casting industry has achieved amazing development and has developed into a new industry. At present, aluminum alloy die-casting parts account for more than 3 / 4 of all die-casting parts, and aluminum alloy die-casting products are widely used in automobiles, telecommunications, motorcycles, home appliances and other industries. . With the improvement of technical level and product development ability, the types and application fields of die-casting products continue to expand, and the die-casting equipment, die-casting molds and die-casting processes have undergone tremendous changes. [0003] Aluminum alloy die-casting mold release agent is an auxiliary agent that must be used in the production process. Due to the large size and complexity of precision molds and the improvement of mold quality and life requirements, and the clamping...
