Abstract
The invention provides a concrete mold releasing agent. The concrete mold releasing agent is prepared from the following components: terminal alkenyl polyoxyethylene ether, acrylic acid, ammonium persulfate, mercaptopropanoic acid, hydrogen peroxide, hydroxylated vegetable oil, sodium gluconate, organic silicon, polyethylene glycol, polyvinyl alcohol, de-ionized water, polyacrylamide, hydrochloricacid and sodium lauryl sulfate. After a certain amount of the sodium gluconate is added, a good mold releasing effect can be realized; the vegetable oil based mold releasing agent is utilized so thatthe surface quality of concrete can be improved; the organic silicon has strong chemical inertness and lubricating property, low surface energy and strong film forming capability, so that the concrete mold releasing agent has an excellent mold releasing property; the organic silicon and the hydroxylated vegetable oil are used as raw materials so that the concrete mold releasing agent is a waterborne mold releasing agent; after being brushed on the surface of a mold, the concrete mold releasing agent is rapidly dried; after moisture is evaporated, a remained effective substance rapidly forms one layer of extremely thin isolation oil film, so that the concrete mold releasing agent not only has an isolation effect, but also has a relatively good lubricating property and has an antirust effect on a steel mold.
Description
technical field [0001] The invention relates to the technical field of concrete admixtures, in particular to a concrete release agent. Background technique [0002] Concrete release agent is a kind of coating or spraying on the inner wall of the formwork, which can produce a layer of isolation film to lubricate and isolate. At the same time, it can effectively reduce the adhesion between the concrete and the formwork, so that the concrete Can be successfully removed from the template. [0003] It is difficult for existing release agents to meet the requirement of not polluting the quality of steel bars and concrete, and the release effect is not ideal. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the invention provides a concrete release agent, which solves the problems that the existing release agent will pollute the quality of steel bars and concrete and the demoulding is inconvenient. [0005] In order to achieve the above object, th...
