Abstract
The invention discloses a mold release agent for a light cement component, and a preparation method and a use method thereof, and belongs to the field of mold release agents. The invention needs to solve the technical problems that a conventional mold release agent is difficult to treat after wear, treatment operation is complicated, the technical requirements are high and difficult to master and the mold service life is shortened. The mold release agent is mainly prepared from organic silicone oil, organic silicon resin, white oil, a composite emulsifier and water. The method comprises the steps: mixing white oil, organic silicone oil and organic silicon resin, then heating up to 80 to 90 DEG C, adding the composite emulsifier, continuing to heat up to 95 to 99 DEG C, stirring and mixing for 30 min, cooling down to 25 to 30 DEG C, adding the required amount of water under strongly stirring, continuing to stir for 30 min, and thus obtaining the mold release agent. The use method comprises that the mold release agent treats the inner surface of a mold by a way of spraying or brushing. The product can be used in the environment of the temperature of above zero; the mold release agent is suitable for mold release in the production of the light cement component, and is especially suitable for mold release in the production of non-autoclaved lightweight building blocks.
Description
technical field [0001] The invention belongs to the technical field of release agents; in particular, it relates to a release agent for lightweight cement components and its preparation method and application method; in particular, it relates to a release agent for the production of autoclaved lightweight blocks and methods of preparation and use thereof. Background technique [0002] A release agent is an interface coating applied to the surface of two objects that tend to stick to each other, which makes the surface of the object easy to release, smooth and clean. [0003] The existing release agent polytetrafluoroethylene has the advantage of good use effect. However, it is difficult to cure, and it needs to be sintered under the condition of 360-400°C. The processing operation is cumbersome, and the technical requirements are high and difficult to master. Difficult to handle after coating wears off. Moreover, the annealing of the mold after high temperature treatment ...
