Problems solved by technology

After further analysis, it is believed that the poor isolation effect is due to the insufficient adhesion between the organic fluorocarbon resin in the coating film and the substrate
For example, when organosilicon and organofluorine resin film materials are used as the main film-forming materials, a large number of non-low surface energy components are introduced into the main chain of organofluorine and organosilicon, resulting in poor isolation effect and low demoulding frequency. question

Abstract

The invention relates to a diacetylenylbenzene type tire release agent, which belongs to the technical field of mold release material processing. In order to solve the existing problem of poor mold release performance, a diacetylenic benzene tire release agent is provided, the tire release agent includes the mass percentage of the following components: diacetylenic benzene compound: 8.0% to 10%; crosslinking agent: 1.0%~2.0%; Emulsifier: 0.5%~1.5%; Stabilizer: 0.1%~0.3%; Water: 85%~90%. The present invention can effectively increase the demoulding frequency of the rubber during vulcanization by adopting the diacetylenic benzene compound, and realize the effect that the continuous demoulding times of one painting can be increased to 4-6 times.

Description

technical field [0001] The invention relates to a diacetylenylbenzene type tire release agent, which belongs to the technical field of mold release material processing. Background technique [0002] Isolation (release) agent is an additive that can form an interface isolation layer on the surface of two objects that are easy to adhere to each other, making the surface of the finished product easy to release, smooth and clean. According to the composition: the existing film-forming materials are mainly wax, siloxane, metal stearate, polyvinyl alcohol, etc. However, on the one hand, with the further requirements of environmental protection issues, the global call for reducing harmful vapors in the working environment is getting louder and louder, making chlorofluorocarbon solvent carriers banned. To this end, a number of new water-based release (mold release) formulations have been introduced for a wide range of applications. [0003] On the other hand, in tire processing an...
