Abstract

The invention relates to the technical field of concrete release agents, in particular to a concrete release agent and a preparation method thereof; the concrete release agent comprises: emulsified oil, the emulsified oil contains heat conduction oil and a co-emulsifier, and the co-emulsifier The antirust agent is diisobutyl dibasic acid; the antirust agent is selected from one or more mixtures of fatty acids, alcohol amines, sodium nitrite, and sodium carbonate. The concrete release agent provided by the invention has good corrosion resistance, excellent thermal conductivity and thermal cracking resistance, can quickly conduct local heat of concrete, improve rebound strength, avoid surface temperature cracks formed during concrete molding, and become After the film, the co-emulsifier will volatilize, will not affect the characteristics of the release agent, and can effectively shorten the drying and film-forming time of the release agent, which has a very wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of concrete release agents, in particular to a concrete release agent and a preparation method thereof. Background technique [0002] With the continuous development of national urbanization and infrastructure construction, the scale of construction projects has also reached new highs. Concrete is the most widely used building material, and its excellent construction performance and mechanical properties ensure the safety of pouring and use of concrete components. However, with the development of architectural design concepts and concrete technology, the requirements for the decorative effect of concrete surface are getting higher and higher. Reasonable use of release agent can effectively improve the appearance of concrete and improve the durability of concrete. [0003] Concrete release agents are generally divided into oil-based release agents and water-based release agents. Oil-based release agents gene...
