Embodiment 1

[0025] A kind of palm oil-based environment-friendly concrete aqueous release agent preparation method, comprises the steps:

[0026] The first step, weigh the following component raw materials in parts by weight: 38 parts of palm oil, 2 parts of water-soluble emulsifier, 2.5 parts of oily emulsifier, 1 part of emulsification aid, 2 parts of substrate wetting agent, 2 parts of waterproofing agent and 0.5 parts of antirust agent;

[0027] The second step, the emulsifier is pre-dispersed in palm oil: put the weighed palm oil into the reactor, and at the stirring speed of 200r / min, add the water-soluble emulsifier into the reactor until the mixed liquid in the reactor is dark. Stop stirring in yellow turbid state;

[0028] The third step, emulsion formation: under the conditions of dispersion speed of 1000r / min and temperature of 45°C, mix oil-soluble emulsifier, emulsification aid, substrate wetting agent, water repellent and rust inhibitor to make emulsified water, Add em...

Embodiment 2

[0037] A kind of palm oil-based environment-friendly concrete aqueous release agent preparation method, comprises the steps:

[0038] The first step, weigh the following component raw materials in parts by weight: 44 parts of palm oil, 2.5 parts of water-soluble emulsifier, 3 parts of oily emulsifier, 1.5 parts of emulsification aid, 2.2 parts of substrate wetting agent, 2.2 parts of waterproofing agent and 0.7 parts of antirust agent;

[0039] The second step, the emulsifier is pre-dispersed in the palm oil: add the weighed palm oil into the reactor, and at the stirring speed of 250r / min, add the water-soluble emulsifier into the reactor until the mixed liquid in the reactor becomes dark. Stop stirring in yellow turbid state;

[0040]The third step, emulsion formation: under the conditions of dispersion speed of 1000r / min and temperature of 45°C, mix oil-soluble emulsifier, emulsification aid, substrate wetting agent, water repellent and rust inhibitor to make emulsified...

Embodiment 3

[0049] A kind of palm oil-based environment-friendly concrete aqueous release agent preparation method, comprises the steps:

[0050] The first step, weigh the following component raw materials by weight: 50 parts of palm oil, 3 parts of water-soluble emulsifier, 3.5 parts of oily emulsifier, 2 parts of emulsification aid, 2.5 parts of substrate wetting agent, 2.5 parts of waterproofing agent and 1 part of antirust agent;

[0051] The second step, the emulsifier is pre-dispersed in the palm oil: put the weighed palm oil into the reactor, and at the stirring speed of 300r / min, add the water-soluble emulsifier into the reactor until the mixed liquid in the reactor becomes dark. Stop stirring in yellow turbid state;

[0052] The third step, emulsion formation: under the conditions of dispersion speed of 1000r / min and temperature of 45°C, mix oil-soluble emulsifier, emulsification aid, substrate wetting agent, water repellent and rust inhibitor to make emulsified water, Add ...

Abstract

The invention discloses a preparation method of a palm oil-based environment-friendly concrete water-based release agent, which takes environment-friendly and renewable palm oil as a raw material, gets rid of the dependence of the traditional release agent on mineral oil, realizes the comprehensive utilization of vegetable oil, and reduces the environmental pollution and the harm to the human body. In the preparation process of concrete products, quality defects such as exposed ribs, honeycomb pitted surfaces, holes and unfilled corners often occur on the surfaces of various components after formwork removal, the decoration effect of the surfaces of the products is affected, and the internal quality and durability of the products are further affected. In order to effectively reduce cohesion between concrete and a formwork, the number of air holes in the surface of the concrete is greatly reduced; demolding is easy, the appearance completeness of the concrete and rust prevention of a steel mold are kept, and the product quality is improved while the product appearance is guaranteed. The palm oil-based environment-friendly concrete water-based mold release agent prepared by the invention is good in mold release effect, non-sticky to a mold plate and high in water scouring resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a palm oil-based environment-friendly concrete water-based release agent. Background technique [0002] The development of concrete technology has been accompanied by the development of human urbanization, and concrete products have become the most widely used building materials in the world. In the process of preparing concrete products, quality defects such as exposed tendons, honeycomb pockmarks, holes, and missing corners often appear on the surface of various components after demoulding, which not only affects the decorative effect of the product surface, but also further affects its internal quality and durability. . The use of the release agent can effectively reduce the cohesion between the concrete and the formwork, and greatly reduce the number of pores on the concrete surface, so as to achieve the purpose of easy demouldi...
