Aluminum alloy template release agent and preparation method thereof

Abstract

The invention discloses a novel concrete water-based release agent applied to aluminum alloy templates. The release agent is composited from range hood gas condensate, an emulsifier, sodium alcohol ether sulfate, a dispersant, a rust inhibitor, a preservative, a thickening agent and water as main raw materials. The involved preparation process is simple and convenient to operate, raw materials arewidely sourced, synthesis temperature is low, and significant economic and environmental benefits are achieved; the obtained water-based release agent has good release performance and good applicability to aluminum alloy templates and cannot corrode a mold, released concrete has smooth and flat concrete surface without large bubbles, less concrete is adhered to the mold, and the release agent issuitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a novel aluminum alloy template release agent and a preparation method thereof. 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 an isolation film, which can lubricate and isolate, and can effectively reduce the gap between concrete and formwork. Adhesive force between them, so that the concrete can be separated from the formwork smoothly when the formwork is removed, and the substance or material that keeps the shape of the concrete intact and smooth. In the process of concrete engineering construction, quality defects such as honeycomb pockmarks, missing corners, and exposed ribs often appear on the concrete surface. The use of release agent can reduce or even avoid many of the above-mentioned problems on the surf...

Problems solved by technology

Most of the oil-based release agents use machine oil or waste machine oil as the main raw material, which is expensive, easy to produce oil mist, and the air in the processing site is highly polluted, which is harmful to the health of the operators. Although this material is easy to release the mold, it is not easy to Dry, easy to pollute the surface of steel bars and concrete, and have adverse effects on the plastering, grouting or pasting of the concrete surface; the emulsification temperature of the emulsified oil release agent is high, the amount of emulsifier used is large, and the stability of the emulsified oil produced is poor , easy to cause delamination, not suitable for long-term storage; water-soluble release agent is low in efficiency, can not be used multiple times after brushing once; paraffin release agent is relatively high cost, and when the paraffin content is high, it is easy to stick to the concrete Leaves a paraffin residue on the surface, hindering the bonding of the concrete surface

Synthetic resin and paint release agents are expensive and difficult to clean

[0004] In view of the problems of high cost, poor stability, low efficiency, and poor adaptability to aluminum alloy templates in various release agents currently on the market, it is urgent to develop a new type of release agent for aluminum alloy templates that is convenient for construction, easy to operate, and environmentally friendly
