Abstract

A special self-emulsifying release agent for lining segments and a preparation method thereof, the raw materials of which include the following components in weight percent: 75-90 parts of polypropylene oxide, 1-25 parts of emulsifier, and 1-25 parts of wetting agent , 1‑2 parts stabilizer. Polypropylene oxide is the core material of this release agent. Its excellent hydrophobic performance can not only play a role in separation, but also make the release agent more resistant to water erosion after film formation. Polypropylene oxide itself is non-toxic and harmless, and it decomposes spontaneously under the sun for a long time, so it is a safe and environmentally friendly product. The self-emulsifying mold release agent of the present invention has simple preparation process, stable product, long storage period and convenient use.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a special self-emulsifying release agent for lining segments and a preparation method thereof. Background technique [0002] Concrete release agent is a type that can prevent concrete components from bonding with molds or other slab surfaces, facilitate demoulding, improve production efficiency, and prolong mold life. At the same time, it can make the surface of concrete products smooth, the size is qualified, and reduce the scrap rate Processing aids. An excellent release agent must have good isolation, fast drying and film formation, no pollution, no oil stains, no influence on the decoration process, no harm to concrete, protection of the formwork, low cost, easy to use, and good stability And harmless to human body. [0003] Commonly used release agents can be divided into: (1) pure oils, including vegetable oils, animal oils and mineral oils; (2) emu...
