Embodiment

[0041] In order to ensure the smooth progress of the emulsification process and the quality of the final product, the main stirred tank (1# stirred tank) in the production of this scheme is equipped with two independent mixers A and B, of which A mixer is equipped with a basket-type stirring head. Its main function It solves the problem that high-viscosity oily materials are easy to stick to the wall and bottom, so that the materials can completely enter the emulsification process system, and avoid the final product containing unemulsified oil phase materials that will affect the quality of the finished product. At the same time, the diversion effect of its reverse stirring can Increase the fluidity and uniformity of the liquid in the stirred tank. The B mixer is equipped with a high-speed homogenizing stirring head, which has excellent homogenizing and emulsifying capabilities to ensure the dispersion stability of the final product.

Abstract

The invention relates to the technical field of mold-release agents, specifically to a water-based aluminum die-casting mold-release agent and a preparation method thereof. The water-based aluminum die-casting mold-release agent comprises the following raw materials in percentages by weight: 35-45% of long-chain alkyl organic silicone oil, 5-8% of fully-synthetic olefin oil, 2-3% of an antirust agent and a composite surfactant, with the balance being water, wherein the composite surfactant is composed of 4-5% of a nonionic surfactant and 0.2-0.5% of an anionic surfactant. The mold-release agent provided by the invention is mainly used for the die-casting industry.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to a water-based aluminum die-casting release agent and a preparation method thereof. Background technique [0002] At present, in the aluminum alloy die-casting industry, water-based aluminum alloy die-casting release agents are usually compounded with animal and vegetable oils and mineral oils, paraffin emulsions and silicone emulsions. Animal and vegetable oils, mineral oils, and paraffin wax have the disadvantages of poor high temperature resistance, perishability, and high impurity content due to the limitation of their own chemical properties. Since aluminum alloy die-casting is a production process in which molten aluminum is injected and then cooled, the high temperature generated in a short period of time will cause pyrolysis and carbonization of animal and vegetable oils, mineral oils and paraffin in the formula, which not only reduces the use of the product Perfor...
