Abstract

The invention relates to a low-viscosity concrete release agent and a preparation method thereof. The low-viscosity concrete release agent is characterized by being prepared from the following ingredients in proportion by weight: 10 to 40 percent of industrial waste oil, 20 to 90 percent of water, 0.1 to 5 percent of surfactants, 0.1 to 5 percent of emulsifiers, 0.1 to 5 percent of anti-rusting agents and 0.1 to 5 percent of antifoaming agents, wherein the ratio of the surfactants to the emulsifiers is controlled to be 1:5. The cyclic utilization of waste materials is realized; and the problem of environment pollution due to industrial waste oil on the environment is solved. The release agent has the advantages that the release effect is good; the surface of a component is smooth; no surface dust exists; no concrete residue exists on a steel mold; the cleaning is convenient; no rust corrosion occurs; and the production cost is low, and the like.

Description

A kind of low viscosity concrete parting agent and preparation method thereof

Technical field

The present invention relates to a kind of low viscosity concrete parting agent and preparation method thereof.

Background technology

The releasing agent of concrete is a kind of spraying（Brush）In the work surface of mould, buffer action is played, the energy in form removal Enough make concrete smoothly separate with mould, and enable to the complete bubble-free of concrete surface to produce and cause mould smooth Clean material.

In recent years, as the infrastructure projects such as high ferro, subway are increasing, a large amount of construction using component are also increased therewith, Particularly beautiful appearance, practicality, the component of convenient construction demand it is increasing, the production pressure of component is also increased therewith, The production for how quickly finishing component is that Concrete Industry is crucial.Adjuvant of the releasing agent as component, before the more than ten years Jing is largely used to Concrete Industry, although existing concrete parting agent product is very more, but for the domestic de- of component production Mould agent never truly substitutes the releasing agent of external import, and its reason is：It significantly reduces concrete cast During component and punching block adhesion, the outward appearance for not only easily causing component is damaged, and causes the adhesion of component and mould, makes Difficult into form removal, labor intensity is increased, and low production efficiency, cleaning mould are difficult,

Therefore, being badly in need of a kind of suitable releasing agent increases the production efficiency of production component, improves the neat appearance of outward appearance.

At present, it is thus well known that releasing agent substantially has：Used oil class, saponin, plant oil, wax oil class, surface activity Agent class, template paint class.

（1）Pure oils releasing agent.Pure oils releasing agent is made as releasing agent with mineral oil, animal oil and vegetable oil With, can the smoothly demoulding, it is domestic with extensive.Advantage is easy to use, and cost is relatively low.Have the disadvantage that its blibbing is difficult to suppress, The phenomenons such as air marks are easily produced, and vegetable and animals oils are apt to deteriorate, scent of；

（2）Emulsion-type releasing agent.Oil dispersed is prepared from water, due to its simple, cheap, effect of making it is good etc. Advantage is with also quite varied.Its principle is that oil dispersed is being formed nano level microsphere in water, the moisture in template is brushed Thin film can be formed after evaporation and plays demoulding effect.

（3）Paint class releasing agent.Such releasing agent is also referred to as demoulding paint, is to brush coast of paint face is formed in template, to the greatest extent Pipe price is higher but can be that recycling is multiple.Have the disadvantage, as its die face is cleared up and repairing all not enough facilitates, to limit The use of this kind of releasing agent.

The content of the invention

It is an object of the invention to provide a kind of low viscosity concrete parting agent and preparation method thereof, to solve existing coagulation There are the problems referred to above in native remover use.

Technical scheme：

A kind of low viscosity concrete parting agent, by weight, including：Industrial waste oil 10～40%, water 20～90%, surfactant 0.1～5%, emulsifying agent 0.1～5%, antirust agent 0.1～5%, defoamer 0.1～5%, control surface activating agent：Emulsifying agent=1～5.

Primary raw material, including used oil, waste diesel and waste oil, add micro emulsifying agent production high efficiency, low cost antirust Concrete parting agent,

Manufacturing process is as follows：

Industrial waste oil is placed in reaction vessel, surfactant 0.1～5%, emulsifying agent 0.1～5%, antirust agent is sequentially added The organic solvent such as 0.1～5% and defoamer 0.1～5%, stirring make emulsifying agent evenly spread in industrial waste oil, form mould oil. Ready moisture batch is added in above-mentioned mould oil, is stirred after adding every time to profit and is formed homogenized milk phase, add down A collection of water, until whole thinned waters are added, is stirred for 10～15 minutes, forms homogenizing white emulsion, finished product packing.

Comprise the following steps that：

Step one, industrial waste oil is mixed in selected ratio taken amount, and put into Body.

Step 2, sequentially add surfactant 0.1～5%, emulsifying agent 0.1～5%, antirust in uniform liquid in proportion The organic solvent such as agent 0.1～5% and defoamer 0.1～5% stirs, and forms mould oil.

Step 3, by the mould oil and water in proportion 1:2～1:9 ratio mixing, stirring obtain concrete demoulding Agent.

Concrete preferred each composition of raw materials：

1, industrial used oil 10.96%；Pulvis Talci 0.55%；Liquid paraffin 0.22%；Dodecylbenzene sodium sulfonate 0.55%；Defoamer 0.055%, water 87.67%.

2, industrial waste diesel 14.01%, Pulvis Talci 0.70%, liquid paraffin 0.28%, dodecylbenzene sodium sulfonate 0.84% disappear Infusion 0.11%, water 84.10%.

3rd, industrial waste oil 11.98%, Pulvis Talci 0.60%, liquid paraffin 0.24%, dodecylbenzene sodium sulfonate 0.72% disappear Infusion 0.18%, water 86.28%.

Good effect：On the one hand accomplish the cyclic utilization of waste, on the other hand solve the ring that industrial waste oil is caused to environment Pollute in border.The releasing agent stripping result is good, component surface is smooth, ash, punching block noresidue concrete are played without surface, is convenient to clean, The advantages of non-corroding and low production cost.
