Organosilicon microemulsion antisticking agent and preparation method thereof

Abstract

The invention relates to an organosilicon micro-emulsion mould release agent which consists of the following compositions in weight percentage: 20 to 35 percent of dimethyl cyclic siloxane, 3 to 7 percent of alkyl triethoxy silane, 2 to 6 percent of fatty alcohol-polyoxyethylene ether, 0.1 to 0.5 percent of ethylenediamine tetracetic acid, 4 to 8 percent of dodecyl benzene sulfonic acid and 50 to70 percent of deionized water; the sum of the compositions is 100 percent; and the PH value is neutral. The organosilicon micro-emulsion mould release agent overcomes the disadvantages that the priorgaseous mould release agent is inflammable and explosive, pollutes environment and the like. The organosilicon micro-emulsion mould release agent has the advantages of convenient use, good mould release effect, low cost and the like. The organosilicon micro-emulsion mould release agent also releases a method for preparing the organosilicon micro-emulsion mould release agent.

Description

Silicone microemulsion release agent and preparation method thereof technical field The invention relates to an organosilicon microemulsion mold release agent, which is used in the mold release process of precision casting wax molds.

Problems solved by technology

Traditional mold release agents generally use aerosol silicone oil (anhydrous, flammable, and explosive gas). Silicone oil has low viscosity, weak surface tension, small surface energy, and strong film-forming ability to prevent wax molds from spraying wax. When bonding with the mold, the molding rate of the wax mold is guaranteed, and the demoulding effect is good, but the hazards are also very serious, specifically the following three disadvantages: 1. Aerosol silicone oil, which belongs to the category of pressure container filling products, Inflammable and explosive, there are great safety risks in the process of transportation, storage and production. A little carelessness in management may cause explosion or fire, which greatly increases the cost of safety management; 2. Aerosol silicone oil, when using spray During the process, the working environment is polluted, resulting in turbid air at the working site, poor air quality in the working environment, poor ventilation in the working environment, and excessive air concentration, which is harmful to the health of workers; 3. The atomizer in the aerosol silicone oil is harmful to the human body and has toxic side effects , Harmful gases form mist particles, which can be absorbed into the blood through the respiratory tract, digestive tract and skin, and distributed throughout the body, anesthetizing the central nervous system, causing fatigue, nausea, dizziness, shortness of breath, convulsions, coma, and long-term exposure can also cause severe drug eruptions Dermatitis, liver, kidney, heart, trigeminal nerve damage, etc., leading to an increase in occupational diseases
