Preparation method of fluorocarbon release agent

Abstract

The invention provides a preparation method of a fluorocarbon release agent. The preparation method comprises the following steps: mixing a perfluoroalkyl acrylate copolymer emulsion, hydrophilic amino silicone oil, a polyoxyethylene polyoxypropylene ether compound, benzotriazole-N,N,N',N'-tetramethylurea hexafluorophosphate, N-methoxyethyl-N-methyl diethyl ammonium tetrafluoroborate and N-[3-(dimethylamino)propyl]docosanamide, and then carrying out high-speed emulsification so as to obtain the fluorocarbon release agent.

Description

technical field

[0001] The invention relates to a preparation method of a release agent, in particular to a preparation method of a fluorocarbon release agent. Background technique

[0002] In the manufacture of polymer material products, the molding method is generally used: the melt or solution material is injected into the mold, and after solidification and molding, the molded product is taken out from the mold. In order to help take out the product from the mold, a mold release agent is generally pre-coated on the mold, so that there is no bond between the product and the mold after cooling, thereby ensuring the quality of the product.

[0003] CN102615747A provides a release agent, which comprises the following components: polysiloxane with silicon-hydrogen bonds, a dehydrogenation condensation reaction catalyst and a solvent. The mold release agent of the present invention is a semi-permanent mold release agent. In addition, it also has the advantages of simple compos...
