Embodiment 1

[0012] The preparation method of novel concrete template release agent comprises the following steps:

[0013] (1) Add 30 parts of mixed high-carbon alcohol, 10 parts of vegetable oil and 5 parts of sodium hydroxide into the container by weight and mix, heat to 100 °C, a large amount of water vapor and a small amount of organic matter will volatilize, continue heating for 2 hours to make the steam basically finished;

[0014] (2) Add 40 parts of water to the mixture in step (1) at a temperature of 80°C, stir evenly, then add 10 parts of waste engine oil, stir evenly, and cool naturally;

[0015] (3) Add 3 parts of stabilizer to the mixture in step (2), and stir evenly to obtain the product.

[0016] The stabilizer is methyl cellulose, which makes the emulsified liquid not easy to precipitate and is easy to sizing; the mixed high-carbon alcohol in this embodiment can be selected from various waste materials containing high-carbon alcohol, and the waste engine oil can be select...

Embodiment 2

[0018] The preparation method of novel concrete template release agent comprises the following steps:

[0019] (1) Add 35 parts of mixed high-carbon alcohol, 15 parts of vegetable oil and 10 parts of sodium hydroxide into the container by weight and mix them, heat to 100°C, a large amount of water vapor and a small amount of organic matter will volatilize, continue heating for 2.5 hours to make the steam basically finished;

[0020] (2) Add 45 parts of water to the mixture in step (1) at a temperature of 85°C, stir evenly, then add 20 parts of waste engine oil, stir evenly, and cool naturally;

[0021] (3) Add 4 parts of stabilizer to the mixture in step (2), and stir evenly to obtain the product.

[0022] The stabilizer is methyl cellulose.

Embodiment 3

[0024] The preparation method of novel concrete template release agent comprises the following steps:

[0025] (1) Add 40 parts of mixed high-carbon alcohol, 20 parts of vegetable oil and 15 parts of sodium hydroxide into the container by weight and mix them, heat to 100°C, a large amount of water vapor and a small amount of organic matter will volatilize, continue heating for 3 hours to make the steam basically finished;

[0026] (2) Add 60 parts of water to the mixture in step (1) at a temperature of 90°C, stir evenly, then add 30 parts of waste engine oil, stir evenly, and cool naturally;

[0027] (3) Add 5 parts of stabilizer to the mixture in step (2), and stir evenly to obtain the product.

[0028] The stabilizer is methyl cellulose.

Abstract

The invention relates to the technical field of concrete releasing agents and particularly relates to a method for preparing a novel concrete form releasing agent. The method comprises the following steps of: adding the following raw materials in parts by weight: 30-40 parts of mixed high-carbon alcohol, 10-20 parts of vegetable oil and 5-15 parts of sodium hydroxide, into a vessel, mixing, heating to the temperature of 100 DEG C until a large amount of water vapor and a small amount of organic matter are subjected to volatilization, and continuously heating for 2-3 hours so as to basically exhaust the vapor. According to the method, the mixed high-carbon alcohol and waste engine oil serve as main raw materials, and the mixed high-carbon alcohol can be prepared from various wastes containing high-carbon alcohols, so that the environmental pollution is reduced, the raw materials are readily available, and the production cost can be reduced by about 25% compared with that of the prior art; the product has a good releasing effect, does not pollute cement parts, does not corrode the form, is non-toxic and odorless, is convenient to use and is not subjected to demulsification, deterioration and layering in long-term storage. In addition, industrial wastes are utilized comprehensively, the waste of resources is avoided, the environmental pollution is reduced, and the releasing agent can be widely applied to the release of the concrete parts and is also applicable to various forms.

Description

technical field [0001] The invention relates to the technical field of concrete release agents, in particular to a preparation method of a novel concrete form release agent. Background technique [0002] There are many types of concrete release agents, which can be divided into water-based release agents, oil-based release agents, paraffin-based release agents, emulsion-based release agents and specially formulated release agents according to the main constituent materials. However, these release agents have disadvantages in specific applications, such as: high cost, complex production process, certain corrosion, unsatisfactory release effect, harmful odor and environmental pollution when used. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of a novel concrete form release agent with low production cost, good demoulding effect, non-toxic, odorless and convenient to use. [0004] In order to solve the existing pro...
