[0018] Embodiment 1: the preparation of release agent

[0019] An anti-corrosion concrete mold release agent, prepared from the following components by weight (kg): sodium hexametaphosphate 8, kerosene 15, potassium fulvic acid 1.5, silica sol powder 12, glyceryl monostearate 10 , sodium lauryl sulfate 5, zircon powder 4, sodium carboxymethyl starch 2, polysorbate-80 1.5, alum 0.8, barium petroleum sulfonate 0.8, additive 3, water 60;

[0020] Among them, the auxiliary agent is made of the following raw materials by weight (kg): aminotrimethylene phosphonic acid 0.2, sodium edetate 1.5, sodium alginate 5, polyethylene glycol 4, gelatin 3, citric acid 0.8, gum arabic 1.5, titanium dioxide 1.5, barium chloride 4, water 50; preparation method of additives: add citric acid, gelatin and gum arabic to water, stir at 60°C for 15 minutes at 200r / min, add the rest of the raw materials, stir at 800r / min for 30min, Instantly.

[0021] Its preparation method comprises the following step...

Embodiment 2

[0025] Embodiment 2: Release agent performance test

[0026] 1. Construction performance of release agent

[0027] After diluting the release agent in Example 1 by 10 times, the performance of the release agent was tested according to the standard of JC / T 949-2005, and the test results are shown in Table 1.

[0028] Table 1 Construction performance of release agent

[0029] Test items index Dry film forming time 19min Release performance Can demould smoothly, the surface is smooth, the concrete adhesion amount is 1.6g / m 2 Water resistance no dissolution Corrosion performance on steel mold no rust

[0030] 2. Stability of release agent

[0031] The release agent stability of embodiment 1 is high, t 稳定时间 >400d, it can be stored for 1 year without oil separation and stratification.

Abstract

The invention discloses an anticorrosive concrete release agent which is prepared from the following raw materials in parts by weight: 5 to 10 parts of sodium hexametaphosphate, 10 to 20 parts of kerosene, 1 to 2 parts of potassium fulvic acid, 10 to 15 parts of colloidal silica powder, 6 to 12 parts of glycerin monostearate, 3 to 6 parts of lauryl sodium sulfate, 3 to 6 parts of zircon powder, 1 to 3 parts of sodium carboxymethyl starch, 1 to 2 parts of polysorbate-80, 0.5 to 1 part of potash alum, 0.2 to 1 part of barium petroleum sulfonate, 2 to 4 parts of auxiliaries and 40 to 80 parts of water. The anticorrosive concrete release agent has excellent anticorrosive performance so as to prolong the service life of a template, and is stable in quality, long in storage time, convenient to use and good in mold release performance and ensures that a mold is easy to release and cannot pollute the surface of a concrete product.

Description

technical field [0001] The invention relates to the field of building concrete, in particular to an anti-corrosion concrete release agent and a preparation method thereof. Background technique [0002] In construction projects, concrete occupies a large proportion, and how to improve the surface quality of concrete components and reduce engineering costs has become the focus of attention. Choosing a release agent with good quality and low cost is one of the key measures to solve this problem. Existing concrete release agents include oils, paraffins, synthetic resins and hydrophilics. At present, the concrete products industry still has problems such as easy rusting of formwork during storage, easy contamination of the concrete surface by release agents, and difficulty in demoulding and cleaning. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-corrosion concrete mold release agent, which not only has excellent anti-corro...
