Embodiment 1-5

[0031] The preparation method of embodiment 1-5 is:

[0032] Weigh each component according to the proportion, heat deionized water to 45-55°C in a water bath, first add octadecyltrimethylammonium chloride to dissolve, and stir thoroughly, then add graphite particles and PTFE particles Stir fully, and finally add the rest of the medicament, stop heating and continue stirring. After the temperature of the mixture drops to room temperature, put it into a pressure tank according to the amount of 300ml per portion, and pour high-purity nitrogen as a propellant to make the pressure in the tank reach 0.3- 0.5MPa is enough.

Abstract

The invention relates to a long-acting environment-friendly release agent and a preparing method thereof. The release agent comprises the following components including NiSO4.6H2O, NaH2PO2.H2O, Na3C6H5O7.2H2O, C2H3NaO2CH3COONa, CuSO4, CH4N2S, PTFE particles, graphite particles, octadecyl trimethyl ammonium chloride and deionized water. According to the long-acting environment-friendly release agent, a composite film formed in the using process can achieve the excellent demoulding effect, and can achieve the effects of protecting a mold and prolonging the service life of the mold. The long-acting environment-friendly release agent overcomes the defects that a traditional release agent is prone to transferring and polluting a product are overcome, so that the long-acting environment-friendly release agent is more suitable for the fields, such as optical products, medical products or food products with high requirements; and the excellent demolding performance can be played for a long time after the release agent is sprayed one time.

Description

【Technical field】 [0001] The invention relates to a long-acting environment-friendly release agent and a preparation method thereof. 【Background technique】 [0002] Plastic molds play an important role in the modern industrial system. With the rapid development of mold design and processing technology and the continuous development of new materials, more and more difficult, high-precision and high-demand products are processed by plastic mold injection molding. Production. A variety of release agents are constantly emerging under such a background, but the existing release agent products all have the following defects. 1. Poor heat resistance, easy to carbonize and decompose and fail. 2. The pH value is acidic, which has a certain corrosion effect on the mold. 3. Easy to transfer and pollute plastic products, especially for optical or medical equipment parts with high requirements. 4. It pollutes the environment and poses a threat to the health of operators. Therefore, ...
