Problems solved by technology

However, among the casting release agents currently used in the industry in our country, inorganic compounds such as mica powder and talcum powder are used as release substances, and organic compounds such as organic acid soaps and stearates are used as release substances. High molecular polymers such as silicone rubber, silicone ester and solvents are used as release components. Although a relatively good release effect is obtained, the product will produce residual pollution on the surface of the product, resulting in difficulty in post-processing, and it is flammable and has poor safety. There is smoke generated during use, and the environmental protection is not up to standard. A qualified release agent requires multiple uses, good release continuity, chemical resistance, heat resistance, not easy to decompose, and easy to coat. At present, the release agent needs Further research and development to meet people's needs

Embodiment 1

[0014] [Example 1] A new type of mixed release agent, including the following raw material formula components in parts by mass: 70-95 parts of graphite milk, 2-3 parts of salt, 7-8 parts of emulsifier, 1-5 parts of polypropylene Amide, 1-2 parts of defoamer, 1-7 parts of silicone resin, 20-30 parts of deionized water.

[0015] The release agent is a functional substance between the mold and the finished product. It is chemically resistant and will not be dissolved when in contact with the chemical components of different resins, especially styrene and amines. The release agent also has Heat and stress resistance, not easy to decompose or wear, the release agent adheres to the mold and does not transfer to the workpiece to be processed, and does not hinder painting or other secondary processing operations.

[0016] 70-100 parts of graphite milk is added to the raw material formula components in parts by mass. The graphite milk has no odor and no toxic gas generation, and has a ...

Embodiment 2

[0024] [Example 2] A new type of mixed release agent, including the following raw material formula components in parts by mass: 70 parts of graphite milk, 3 parts of salt, 7 parts of emulsifier, 1 part of polyacrylamide, 1 part of defoamer, 3 parts silicone resin, 20 parts deionized water.

[0025] The preparation process is as follows:

[0026] Add graphite milk and silicone resin into a container, heat to 50-65°C, stir and dissolve to make an oil phase solution, put salt into another container, add appropriate amount of deionized water to dissolve completely, and then add polyacrylamide , after stirring evenly, add emulsifier, finally add defoamer, stir evenly and heat to 60-80°C to make water phase solution; The water phase is slowly added to the oil phase. At this time, it is necessary to stir quickly and add a small amount to make it emulsify slowly, invert the phase, and make the solution uniform. The stirring speed is gradually slowed down as the emulsification temperatu...

Embodiment 3

[0027] [Example 3] A new type of mixed release agent, including the following raw material formula components in parts by mass: 85 parts of graphite milk, 2 parts of salt, 8 parts of emulsifier, 3 parts of polyacrylamide, 2 parts of defoamer, 4 parts silicone resin, 25 parts deionized water.

[0028] The preparation process is as follows:

[0029] Add graphite milk and silicone resin into a container, heat to 50-65°C, stir and dissolve to make an oil phase solution, put salt into another container, add appropriate amount of deionized water to dissolve completely, and then add polyacrylamide , after stirring evenly, add emulsifier, finally add defoamer, stir evenly and heat to 60-80°C to make water phase solution; The water phase is slowly added to the oil phase.

Abstract

The invention discloses a novel releasing agent. The novel releasing agent is prepared from the following raw materials and formulation components in parts by weight: 70 to 95 parts of aquadag, 2 to 3 parts of edible salt, 7 to 8 parts of an emulsifying agent, 1 to 5 parts of polyacrylamide, 1 to 2 parts of a defoamer, 1 to 7 parts of organic silicon resin and 20 to 30 parts of deionized water. The novel releasing agent disclosed by the invention has good heat insulation and heat control effects; the service life of a mold can be prolonged, and the casting quality can be improved; the novel releasing agent has good lubricating property, releasing property, chemical stability and high-temperature adhesiveness, is unlikely to produce a chemical reaction, is easy for coating, has extremely high heat resistance, is unlikely to age the coating, is unlikely to freeze and solidify at too low temperature, and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of mold release, and in particular relates to a novel mixed mold release agent. Background technique [0002] Casting is the process of smelting metal into a liquid that meets certain requirements and putting it into a mold, cooling, solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. Because the casting blank is almost formed, it achieves the purpose of free machining or a small amount of processing, which reduces the cost and reduces the production time to a certain extent. Casting is one of the basic processes of the modern device manufacturing industry. However, the casting process is relatively An important step, directly related to the quality of the casting. The release agent is a functional substance between the mold and the finished product. It is an interface coating used on the surface of two objects that are easy to adhere to each other. It can make th...
