Problems solved by technology

[0002] The aluminum alloy material is heated and melted, injected into the mold cavity under high pressure in a liquid state, and released from the mold in a short time. In order to ensure the smooth release of the product, a release agent must be sprayed on the surface of the mold cavity before injection. Traditional oily The release agent emits black smoke during use, pollutes the production environment, and is easy to pollute the surface of the aluminum alloy due to its strong oiliness; due to the high cost of the powder release agent, it is seldom used in China

Embodiment 1

[0016] A kind of aluminum alloy mold release agent, is made up of the raw material of following parts by weight:

[0017]

[0018]

[0019] Preparation method: Taking the preparation of an aluminum alloy formwork release agent as an example, the preparation method of an aluminum alloy formwork release agent provided in this example is described as follows:

[0020] (1) Weigh polyethylene wax, polyvinyl alcohol, silicone oil, borax, talcum powder, sodium dodecylbenzenesulfonate, cetyltrimethylammonium chloride, oxypropylene oxide ethylene glyceryl ether, water , into the enamel cylinder;

[0021] (2) Then add Span-80 and OP-10 according to the formula, and slowly raise the temperature while stirring. After the material is completely melted and reaches a temperature of 120°C, slowly add dichlorophen and corrosion inhibitor into the enamel tank, and wait for 10 minutes. Added inside;

Abstract

The invention provides a release agent for an aluminum alloy mold and a preparation method of the release agent. The release agent comprises, by weight, 10-20 parts of polyethylene wax, 1-5 parts of polyving akohol, 4-9 parts of silicone oil, 2-6 parts of boraxes, 19-27 parts of talcum powder, 6-14 parts of sodium dodecyl benzene sulfonate, 0.2-1.3 parts of cetyltrimethylammonium chloride, 5-10 parts of compound emulsifiers, 0.05-0.2 part of dichlorophen, 0.1-0.25 part of oxygen propylene ethylene oxide glyceryl ether, 0.2-1.4 parts of inhibiters, and 60-90 parts of water. The preparation method of the release agent comprises the steps that the raw materials are weighed according to the formula, and then stirred and cooled, and thus the release agent for the aluminum alloy mold is obtained. The release agent prepared through the method is safer, clean and free of pollution; compared with a traditional oil-based release agent, the release agent has the advantages that the cooling effect is good, accumulation is avoided, and the surface quality of castings is good; and compared with a powdery release agent, the release agent has the advantage of being low in cost.

Description

technical field [0001] The invention relates to the technical field of a release agent, in particular to an aluminum alloy template release agent and a preparation method thereof. Background technique [0002] The aluminum alloy material is heated and melted, injected into the mold cavity under high pressure in a liquid state, and released from the mold in a short time. In order to ensure the smooth release of the product, a release agent must be sprayed on the surface of the mold cavity before injection. Traditional oily The release agent emits black smoke during use, pollutes the production environment, and is easy to pollute the aluminum alloy surface due to its strong oiliness; the powder release agent is seldom used in China due to its high cost. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides an aluminum alloy template release agent and a preparation method thereof. [0004] In order to achieve the above...
