Abstract

The invention discloses a spray-coating release agent for artificial stone production, a preparation method and a use method thereof, which comprise the following raw materials: polyvinyl alcohol, paraffin, hydrotalcite powder, magnesium silicate, aluminum magnesium silicate, zinc oxide, Magnesium Hydroxide, Teflon, Cellulose, Xanthan Gum, Sodium Tripolyphosphate, Sodium Carbonate, Modified Camellia Oil, 1-Dodecyl-3-Methylimidazole Nitrate, Octadecylsuccinic Acid Dipotassium monoamide sulfonate, the release agent is made through steps such as dissolving polyvinyl alcohol and mixing with additives. The method of use is to spray the mold release agent on the surface of the artificial stone production mold, and after natural drying and curing, an anti-bonding coating is formed on the surface of the mold. The present invention uses polyvinyl alcohol, paraffin, modified camellia oil, 1-dodecyl-3-methylimidazole sodium nitrate, and dipotassium octadecylsuccinic acid monoamide sulfonate as the reinforcement system, which has a synergistic effect , synergistically shorten the drying and film forming time, shorten the production cycle and improve the efficiency.

Description

【Technical field】 [0001] The invention belongs to the technical field of release agent preparation, and in particular relates to a spray-on release agent for producing artificial stone, a preparation method and a use method thereof. 【Background technique】 [0002] Artificial stone is made by mixing calcium carbonate, aluminum oxide, silicon oxide and other aggregates with adhesives, filling them into molds made of steel, wood and other materials, and curing them after vacuum extrusion or vacuum pressure vibration molding. kind of building material. Generally, kraft paper, kraft cardboard, etc. are placed on the surface of the mold to isolate the contact between the artificial stone material and the surface of the mold to achieve the purpose of demoulding. There is also an oil-based release agent coated on the surface of the mold to prevent the artificial stone material from sticking to the surface of the mold. Use kraft paper and kraft cardboard as a release agent. During ...
