Embodiment 1

[0040] An environment-friendly release agent for concrete, comprising raw materials in parts by weight: 35-55 parts of waste oil treatment liquid, 10-30 parts of thickener, and the thickener is made of bentonite.

[0041] A concrete environmental protection mold release agent in this embodiment adopts waste oil treatment liquid as raw material, and the waste oil treatment liquid is a liquid state after successively removing impurities, purifying and deodorizing, and distilling and removing water from waste oil as raw material The oil body, due to the pre-treatment to remove the odor of the waste oil, avoids the impact on the environment and human health during the preparation of the release agent. The main ingredients make the release agent have a good release effect, so that the waste oil treatment liquid can be used directly as a release agent. At the same time, the raw material components are all common industrial raw materials, the source of materials is more convenient, an...

Embodiment 2

[0044] The concrete environmental-friendly release agent of this embodiment has the same composition as that of Embodiment 1, the difference is that it also includes raw materials in parts by weight: 1-5 parts by weight of fly ash.

[0045] A kind of concrete environment-friendly demoulding agent of this embodiment adds fly ash to the raw material, because there are more spherical particles in the inactive state in the fly ash, it has better fluidity, so that the demoulding effect is better, avoiding The surface quality of the test block is damaged during demoulding, and the demoulding effect is better.

Embodiment 3

[0047] A kind of concrete environment-friendly release agent of this embodiment has the same composition as that of Embodiment 2, the difference is that: it also includes raw materials in parts by weight: 15-35 parts of animal fat and / or 10-30 parts of paraffin wax.

[0048] A kind of concrete environmental protection release agent of the present embodiment, by adding animal fat and / or paraffin in the release agent that is made by waste oil and thickener, because the main component of animal oil is palmitic acid, stearic acid Triglycerides, animal fats and paraffins can be used as release agents respectively, and cooperate with the oil body made from waste oil to provide a good way for the recovery and utilization of waste oil, so that the release agent made from waste oil The demoulding effect of the agent is better, and at the same time, since the animal fat and paraffin all have the characteristics of natural solidification after cooling, the prepared demoulding agent can be...

Abstract

The invention relates to a demoulding agent and a preparation method thereof in the field of construction, in particular to an environment-friendly concrete demoulding agent and a preparation method thereof. The environment-friendly concrete demoulding agent is prepared from, by weight, 35-55 parts of swill-cooked dirty oil treatment liquid and 10-30 parts of a thickening agent, wherein the thickening agent is prepared from bentonite. The preparation method includes: step 1, preparing swill-cooked dirty oil treatment liquid; step 2, preparing mixed stock solution; step 3, extracting the liquid demoulding agent. By adoption of swill-cooked dirty oil as a raw material, a rich triglyceride component in swill-cooked dirty oil serves as a main component of the demoulding agent to enable the demoulding agent to have great demoulding effects; due to adoption of bentonite as one of raw materials, a great isolation layer is formed between a mould and a test piece by bentonite according to a characteristic that bentonite is capable of expanding after adsorption of liquid substances, and accordingly the demoulding effects of the demoulding agent is further improved; the preparation method is simple, and a great way is provided for environment-friendly recycling of swill-cooked dirty oil.

Description

technical field [0001] The invention relates to a release agent in the construction field and a preparation method thereof, in particular to an environmentally friendly concrete release agent and a preparation method thereof. Background technique [0002] Waste oil is a general term for waste animal grease, swill oil, repeated heating and use, and garbage oil collected from the sewer of catering enterprises. Waste oil is due to its total number of bacteria, peroxide value, acid value, moisture, carbonyl value, malondialdehyde, Heavy metals, acrolein and other indicators seriously exceed the standard, and can no longer be used as edible oil. However, due to the large amount of waste oil produced by the catering industry in our country every day, and there is no good way to recycle the waste oil, some businesses have illegally disposed of the waste. The oil is then put into consumption, causing greater harm to the human body. [0003] At present, the Chinese patent applicatio...
