Abstract

The invention discloses a high-dilution-rate and environment-friendly release agent for an aluminum alloy, which consists of a synthetic lubricant, organic acid, organic amine, inorganic base, a surfactant, an anti-corrosive agent, silicone oil and pure water. The release agent is good in heat resistance, absorptivity and cooling property, and is safe to people and the environment.

Description

technical field [0001] The invention relates to a die-casting demoulding of aluminum alloy materials for machining enterprises such as automobiles, motorcycles and household appliances. Background technique [0002] With the development of China's economy, the large-scale, complex and high-quality requirements of precision molds, die-casting equipment, and die-casting products, as an auxiliary aluminum alloy die-casting mold release agent that must be used in the aluminum alloy die-casting production process, its performance requirements are also increasing. Higher and higher, the demand for high-performance aluminum alloy release agents is also increasing. In addition, with the continuous expansion and wide application of aluminum alloy die-casting types and application fields, a lot of changes have taken place in its die-casting equipment, die-casting molds and die-casting processes. The major changes not only require higher and higher performance and quality requirements ...
