Problems solved by technology

The commonly used release agent on the market is oil-based release agent. The traditional oil-based release agent has high viscosity and consistency, and the air bubbles are not easy to overflow, causing pores to appear on the surface after the formwork is removed, and seriously affect the concrete adhesion and affect the quality of the project; Compared with water-based release agents, the cost is high and there are potential safety hazards; while water-based release agents are simple and safe to use, and the most important thing is environmental protection. It can also reduce various defects on the concrete surface and improve the strength of concrete.

Abstract

The invention discloses an aqueous demolding agent and a preparation method thereof. The aqueous demolding agent comprises the following raw materials in parts by weight: 30-50 parts of oil, 5-15 parts of filming substances, 5-12 parts of an emulsifier, 1-20 parts of aids, 0.1-0.5 part of a stabilizer, 0.5-1 part of an anti-rusting agent, 0.1-0.5 part of a corrosion resistant agent and 60-200 parts of water. The demolding agent can be prepared at an increased temperature or a room temperature, and has the characteristics of being good in stability, easy to demold, small in amount, small in concrete adhesion amount, small in pollution, and the like.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to a water-based release agent and a preparation method thereof. Background technique [0002] The release agent is a functional substance between the mold and the finished product. The commonly used release agent on the market is oil-based release agent. The traditional oil-based release agent has high viscosity and consistency, and the air bubbles are not easy to overflow, causing pores to appear on the surface after the formwork is removed, and seriously affect the concrete adhesion and affect the quality of the project; Compared with water-based release agents, the cost is high and there are potential safety hazards; while water-based release agents are simple and safe to use, and the most important thing is environmental protection. It can also reduce various defects on the concrete surface and improve the strength of concrete. [0003] At present, with the continuous d...
