Problems solved by technology

Its disadvantages are: it is difficult to cure, and it needs to be sintered and solidified at 360°C-400°C, and the technical requirements are high and difficult to master.
It brings about three other problems: (1) The fluorine element released at high temperature is a toxic gas; (2) The mold is not durable after annealing at high temperature; (3) The mold wears seriously after sandblasting, so the service life of the mold is shortened; (4) The processing operation is cumbersome and requires high technical personnel; (5) It requires high temperature sintering and high energy consumption

Abstract

The invention relates to a nano organic silicon mold release agent which comprises the following substances in parts by weight: 2-8 parts of nano silicon dioxide, 15-25 parts of organic silicon resin, 0.5-3 parts of alcohol ester-12, 0.1-1 part of silicon 69, 0.1-1 part of dispersing agent and 60-80 parts of ethanol. The application method comprises the following steps: uniformly mixing the materials to prepare the nano organic silicon mold release agent for later use; and spraying the nano organic silicon mold release agent onto a clean rubber stopper mold surface, curing at normal temperature for 1.5-3 hours, and putting the mold into use. The product is cured at normal temperature, has the advantages of high durability and low damage to the mold, is easy to clean and prolongs the service life of the mold.

Description

technical field [0001] The invention relates to a nano-scale organic silicon release agent and a using method thereof, which are mainly used in the technical field of processing rubber plug molds. Background technique [0002] The surface of the rubber stopper vulcanization mold is sprayed with a release agent. The release agent polytetrafluoroethylene (Teflon) coating currently used in the world is considered to be the best top release agent. The outstanding advantages of this coating are: [0003] 1. High temperature resistance, can be used continuously for more than 360 hours at 200°C. [0004] 2. Easy to demould, the demoulding effect is the best at present. [0005] 3. It is firmly combined with the surface of the metal mold and is not easy to fall off. [0006] Corrosion resistance, any solvent, activator, acid and alkali treatment are ineffective to the coating. Its disadvantages are: it is difficult to cure, and it needs to be sintered and solidified at 360°C-400°...
