Glass mould release agent

Abstract

The invention discloses a glass mould release agent, which is prepared by mixing boron nitride, grease, an emulsifier, water and other components. The glass mould release agent is an emulsified oil type glass mold lubricant release agent prepared by coating the boron nitride with the high viscosity grease and blending water under the action of the emulsifier. The emulsified oil type glass mold lubricant release agent has the advantages of good stability, good demolding performance, thin oil film and even distribution. The glass mould release agent can greatly improve the yield of a machine-prepared bottle, reduces the consumption of the lubricating release agent, and purifies the production environment.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a glass mold release agent. Background technique [0002] With the rapid development of my country's wine, food, beverage and other industries, the demand for various packaging glass bottles and jars has increased. The determinant bottle making machine has become the mainstream model of glass bottle production and is widely used, and the running speed of the determinant machine is getting faster and faster, and the requirements for the glass mold lubricating and releasing agent are getting higher and higher. The traditional method of lubricating and demolding glass molds uses manual or mechanical spraying of animal and vegetable oils, and the general effect is not good. The use of process lubricating materials significantly improves the effect of lubricating and demolding. At present, graphite is the basic material of the most widely used process lubricant materials, and the dosag...

Problems solved by technology

At present, graphite is the basic material of the most widely used process lubricant materials, and the dosage forms are divided into two categories. One is water-based lubricants, which are made of water-based lubricants with high-temperature adhesives and other additives. One-time brushing On the surface of the mold, it is used after drying to form a film. Although this type of lubricating release agent can run for a long period of time, it needs to stop frequently to rebuild the lubricating film on the surface of the mold; the other type uses oil as the medium and adds additives. It is made into oily lubricant, which is continuously brushed or sprayed during the operation of the determinant bottle making machine. Although this type of lubricating and releasing agent realizes continuous operation, the consumption of lubricating and releasing agent is relatively large, and a large amount of oily smoke is generated, which pollutes the working environment
