Problems solved by technology

[0003] The epoxy resin release agent in the prior art, also known as release agent, is used in the form of self-spraying film formation, which is easy to operate; however, for molds with complex-shaped structural products, the spraying is not in place, which is easy to cause It is not easy to demould, and the product qualification rate is low, especially for products with complex product structures, small workpieces and high performance requirements, it is more difficult to realize, which greatly reduces the qualification rate of the prepared products
[0004] In order to solve the above technical problems, a large number of epoxy resin release agents have appeared in the prior art, but due to the unreasonable design of the raw material ratio, the film formation speed is slow, the demoulding is difficult, and the obtained product The appearance of the product is not perfect, and the performance of the product is poor

Embodiment 1

[0030] A new type of epoxy resin mold release agent. The raw material components are high vacuum silicone grease: gasoline: absolute ethanol = 1g: 3.5 mL: 0.55 mL by weight.

[0031] The gasoline is 120# gasoline.

[0032] The anhydrous ethanol is an absolute ethanol with a mass concentration of 95%.

[0033] The preparation method is to mix the high-vacuum silicone grease and gasoline uniformly, stir to make the high-vacuum silicone grease completely dissolve in the gasoline; then add anhydrous ethanol and stir it evenly.

[0034] The stirring speed is 50 r / min; and after the high-vacuum silicone grease is dissolved in gasoline, it is allowed to stand for 10 minutes, and then absolute ethanol is added to it.

[0035] In the described method, after adding absolute ethanol, it is uniformly stirred, and then placed under a vacuum of 0.03 MPa for 5 minutes.

[0036] The application of the new epoxy resin release agent is to soak the cleaned potting mold in the release agent for 2 minutes an...

Embodiment 2

[0039] A new type of epoxy resin mold release agent. The raw material components are high-vacuum silicone grease: gasoline: absolute ethanol = 2g: 8mL:1mL by weight.

[0040] The gasoline is 180# gasoline.

[0041] The anhydrous ethanol is an absolute ethanol with a mass concentration of 99%.

[0042] The preparation method is to mix the high-vacuum silicone grease and gasoline uniformly, stir to make the high-vacuum silicone grease completely dissolve in the gasoline; then add anhydrous ethanol and stir it evenly.

[0043] The stirring speed is 100 r / min; and after the high-vacuum silicone grease is dissolved in gasoline, it is allowed to stand for 20 minutes, and then absolute ethanol is added to it.

[0044] In the described method, after adding absolute ethanol, after it is evenly stirred, it is placed under a vacuum of 0.02 MPa for 10 minutes.

[0045] The application of the new epoxy resin release agent is to soak the cleaned potting mold in the release agent for 1 min, and vibrate...

Embodiment 3

[0048] A new type of epoxy resin mold release agent. The raw material components are high vacuum silicone grease: gasoline: absolute ethanol = 1g: 4mL: 0.53mL in terms of weight ratio.

[0049] The gasoline is 180# gasoline.

[0050] The anhydrous ethanol is an absolute ethanol with a mass concentration of 95%.

[0051] The preparation method is to mix the high-vacuum silicone grease and gasoline uniformly, stir to make the high-vacuum silicone grease completely dissolve in the gasoline; then add anhydrous ethanol and stir it evenly.

[0052] The stirring speed is 200 r / min; and after the high-vacuum silicone grease is dissolved in gasoline, it is allowed to stand for 15 minutes, and then anhydrous ethanol is added to it.

[0053] In the described method, after adding absolute ethanol, it is uniformly stirred, and then placed under a vacuum of 0.06 MPa for 8 minutes.

[0054] The application of the new epoxy resin release agent is to soak the cleaned potting mold in the release agent for...

Abstract

The invention relates to the technical field of manufacturing of epoxy resin release agents, in particular to a novel epoxy resin release agent and a preparation method and application thereof. By means of ratio design of high vacuum silicone grease, gasoline and absolute ethyl alcohol, the novel epoxy resin release agent is reasonable in ratio, mold release is easy after the novel epoxy resin release agent is used for mold release treatment, the appearance surface of a product is full, the film forming speed is moderate, and formed films are evenly distributed in a mold; and no film sticking phenomenon happens, the mold release difficulty is reduced, the mold release efficiency is improved, and the product quality is improved.

Description

Technical field [0001] The invention relates to the technical field of epoxy resin mold release agent production, in particular to a novel epoxy resin mold release agent and a preparation method and application thereof. Background technique [0002] Epoxy resin is widely used. In its application process, not only thermal performance, mechanical performance, chemical performance, and environmental resistance are required, but also the service life and production efficiency of the product must be guaranteed. Potting using the characteristics of epoxy resin is a commonly used method in my country's motor products. It is necessary to ensure the insulation stability of the epoxy resin used in the motor under normal and thermal conditions, as well as its mechanical properties and environmental performance. And the appearance requirements of potting. Therefore, in the process of processing, when epoxy potting is used for processing, it must use corresponding tooling for processing opera...
