Problems solved by technology

Most of the existing die-casting release agents are prepared by emulsifying mineral oils such as hydraulic oil, silicone oil, and modified silicone oil. However, the biodegradation rate of mineral oil is only 10-30%, which seriously pollutes the environment.

Embodiment 1

[0019] The preparation of embodiment 1 water-based aluminum alloy release agent

[0020]

[0021] The preparation method is as follows:

[0022] (1) Take long alkyl chain phenyl modified silicone oil, glyceryl trioleate, oxidized polyethylene wax, glycerol monooleate, isomerized decanol polyoxyethylene ether, long chain fatty alcohol polyoxyethylene ether, Ionized water, mixed and heated to melt.

[0023] (2) Stir the above components at a speed of about 3000 rpm for 20 minutes, cool down to 60°C,

[0024] (3) Then three batches of deionized water will be slowly dripped in, and then stirred for half an hour to prepare,

[0025] Most of the cast steel zircon powder coatings currently on the market are expensive and radioactive.

[0026] The water-based aluminum alloy release agent has low cost, stable performance and good release effect, and greatly reduces environmental pollution while ensuring the high-temperature performance of the release agent.

Embodiment 2

[0027] Example 2 The composition of the water-based aluminum alloy release agent according to the mass ratio is: 30 parts of long alkyl chain phenyl modified silicone oil, 120 parts of glyceryl trioleate, 20 parts of oxidized polyethylene wax with a melting point of 98-100 °C, 15 parts of mono Glyceryl oleate, 5 parts of isomeric decanol polyoxyethylene ether, 10 parts of AEO9, 750 parts of deionized water.

[0028] The preparation method is the same as in Example 1.

[0029] The water-based aluminum alloy release agent has low cost, stable performance and good release effect, and greatly reduces environmental pollution while ensuring the high-temperature performance of the release agent.

Embodiment 3

[0031] The composition of the water-based aluminum alloy release agent according to the mass ratio is: 30 parts of long alkyl chain phenyl modified silicone oil, 120 parts of glycerol trioleate, 40 parts of oxidized polyethylene wax with a melting point of 98-100 °C, and 15 parts of glycerin monooleate Esters, 8 parts of isomeric decanol polyoxyethylene ether, 10 parts of AEO9, 850 parts of deionized water.

[0032] The preparation method is the same as in Example 1.

[0033] The water-based aluminum alloy release agent has low cost, stable performance and good release effect, and greatly reduces environmental pollution while ensuring the high-temperature performance of the release agent.

[0034] The performance investigation of the die-casting release agent prepared by embodiment

[0035] The release performance test method is as follows: Dilute the die-casting release agent with deionized water in a certain proportion (150 times dilution here), spray the diluted solution e...

Abstract

The invention discloses a water-based alumium alloy releasing agent. The water-based alumium alloy releasing agent comprises, by mass, 20-30 parts of long alkyl chain phenyl modified organic silicone oil, 100-150 parts of olein, 20-40 parts of oxidized polyethlene wax, 10-15 parts of glycerol mono-oleate, 700-850 parts of deionized water, 3-8 parts of isomeric alcohol ethoxylates and 5-10 parts of long-chain fatty alcohol-polyoxyethylene ether. According to the environment-friendly die casting releasing agent, the long alkyl chain phenyl modified organic silicone oil with the low proportion and plant oil with the high proportion serve as composite lubricating oil, the high-temperature performance of the releasing agent is guaranteed, and the environment pollution is greatly reduced. After composite emulsification is conducted on the environment-friendly die casting releasing agent through a composite surfactant, preparing is simple, and the obtained releasing agent is excellent in releasing effect.

Description

technical field [0001] The invention belongs to the technical field of casting coatings and synthesis techniques thereof, and in particular relates to a water-based aluminum alloy release agent and a preparation method thereof. Background technique [0002] Release agent is an essential auxiliary agent for the production of metal die casting products. Its main function is to help the metal die casting product to be removed from the mold, and to maintain the integrity and post-processing of the product. [0003] The die-casting release agents currently on the market are generally water-soluble emulsion types. Most of the existing die-casting release agents are prepared by emulsifying mineral oils such as hydraulic oil, silicone oil, and modified silicone oil. However, the biodegradation rate of mineral oil is only 10-30%, which seriously pollutes the environment. Vegetable oil has the advantages of low toxicity and easy biodegradation. As people pay more attention to envir...
