Abstract

The invention discloses a high-stability concrete release agent which is prepared from the following components in percentage by weight: 30-40% of an oil raw material, 2-5% of an emulsifier, 1-3% of an auxiliary agent, 0.2-1% of a stabilizer, 0.1-0.3% of a high-molecular polymer and the balance of water. Vegetable oil or waste grease is adopted as base oil, the waste grease is a mixture of vegetable oil and animal oil, both the vegetable oil and the waste grease are renewable substances, and in addition, the problem of environmental pollution can be further solved by adopting the waste grease. The emulsifier added in the concrete release agent has efficient stability, the added triethanolamine can effectively prevent rust, and the added high-molecular polymer can improve the release effect. The concrete release agent has the advantages of being environmentally friendly, high in stability and capable of being repeatedly used after being applied once. Moreover, the surface strength of concrete can be improved, the weather resistance of concrete is effectively improved, and the service life of a concrete member is prolonged.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a high-stability concrete release agent. Background technique [0002] Concrete release agent, also known as concrete release agent or release lubricant, is a kind of coating or spraying on the inner surface of the formwork, which can produce a layer of isolation film to lubricate and isolate, and can effectively reduce the adhesion between concrete and formwork The substance or material that enables the concrete to be demoulded smoothly when the formwork is removed, and keeps the shape of the concrete intact and clean. [0003] With the rapid development of concrete, the use of concrete release agents is becoming more and more extensive. At present, there are many types of concrete on the market. Different types of release agents have different effects on the release between concrete and formwork. Release agents The main types are as follows: [0004] Emulsifi...
