Problems solved by technology

Release agents such as traditional engine oil and diesel pollute the surface of steel bars and concrete, and the release effect is average
The use of mineral oil release agents causes mineral oil to be lost in the environment, polluting the environment, and engine oil, diesel oil, and mineral oil are all non-renewable resources
As an environmentally friendly release agent, vegetable oil-based release agents have the advantages of being renewable, biodegradable, and harmless to the human body. There are defects, that is, the mold is stained with dust, and the release performance is not good

Abstract

The invention discloses a polysilsesquioxane (POSS) modified vegetable oil emulsion mold release agent and a preparation method thereof. The mold release agent is obtained by taking vegetable oil as a substrate and POSS-vegetable oil polymer as a modifier and adding an emulsifier, an antifoaming agent and a stabilizer. The mold release agent comprises the following raw materials in percentage by mass: 10 to 20 percent of vegetable oil, 0.1 to 1 percent of POSS-vegetable oil polymer, 1 to 3 percent of emulsifier, 0.2 percent of antifoaming agent, 0.1 percent of stabilizer and the balance of deionized water. The mold release agent has a good mold release effect and high peeling performance, is environment-friendly and is harmless to human bodies, the surface of concrete is smooth, flat and non-defective after a mold is released, a little concrete is adhered to the mold, and a template is not corroded.

Description

1. Technical Field [0001] The invention relates to a release agent and a preparation method thereof, in particular to a POSS modified vegetable oil emulsion release agent and a preparation method thereof, belonging to the technical field of building materials. 2. Background technology [0002] Concrete release agent, also known as concrete release agent or release lubricant, is a natural or chemical that is applied to the inner wall of the formwork for lubrication and isolation, so that the mixed soil can be removed from the formwork smoothly after hardening, and keep the concrete shape intact. material. [0003] For a long time, domestic oil, diesel, mineral oil, soap, saponified animal and vegetable oil scraps have been mainly used as mold release agents. Mold release agents such as traditional engine oil and diesel pollute the surface of steel bars and concrete, and the effect of mold release is average. The use of mineral oil release agents causes mineral oil to be lost to th...
