Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of its preparation side of gutter oil cement board additive
Method.
Background technology
With China's economic development and the raising of material life, a large amount of gutter oils are produced, if these gutter oils flow into food and drink
Market will cause and its great food safety hazards.Supervision only by government can not fundamentally solve this hidden danger, and ground
The recycling of ditch oil, can solve the whereabouts of gutter oil from source, allow it to be used for safe, suitable purposes.Trench
Main component in oil is long chain triglycerides, and wherein long chain fatty acids are stearic acid, palmitic acid and oleic acid.At present,
The research direction of disposal gutter oil probably has：With trench oil refinement into fuel oil, combustion gas and lubricating oil etc., work is used as by the use of gutter oil
The soapmaking of industry raw material, refining take other chemical products etc..If can be efficient, economic be able to again using gutter oil as the raw material of industry is sharp
With turning into a problem urgently to be resolved hurrily.
As China is largely put into use to the attention of environmental protection and the requirement of building energy conservation, wall thermal insulation technology, wherein,
Cement foam board due to its thermal conductivity factor is low, resistance to combustion, waterproof, with wall cohesive force is strong, service life is permanent, nonhazardous and radiation
Property, it is a kind of preferably wall thermal insulating energy-saving material.The production of cement board, it is to be added to hydrogen peroxide to mix in advance to put
In cement slurry, bubble cement slurry is produced by decomposing hydrogen dioxide solution and forms porous light-weight material, is cut into after to be hardened
For board type insulant.In decomposing hydrogen dioxide solution foaming process, it is necessary to foam stabilizing component is added in cement slurry, to ensure dioxygen
Fine and closely woven, the uniform presence of bubble energy caused by after after moisture, and keep certain mechanical strength to remain porous until cement initial set
Dead load, current most commonly used foam stabilizer is calcium stearate.When calcium stearate is as cement foam board foam stabilizer, due to it
Not soluble in water, the dispersibility in cement slurry is limited, the problem of volume is larger be present.
The content of the invention
The present invention a kind of gutter oil cement board additive its preparation method of offer, the additive using gutter oil as
Primary raw material, there is excellent foam stability energy and water resistance, and the preparation method being related to is simple, is adapted to popularization and application.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of preparation method of gutter oil cement board additive, comprises the following steps：
1) potassium hydroxide is added to the water and is heated to 75~80 DEG C, added gutter oil, treat gutter oil complete hydrolysis, Ran Houjia
Heat collects separating obtained solid, separation and recovery gained liquid-packing is standby to 105~110 DEG C of progress separation of solid and liquid；
2) the separating obtained solid dissolving of step 1) in 80 DEG C of water and is sufficiently stirred, treats that solid is completely dissolved, by solution
25 DEG C are cooled to, cellulose ether and ammoniacal liquor is added, is stirred well to form homogeneous emulsion, is described gutter oil foam cement
Plate additive.
In such scheme, the step 1) each component is calculated by weight as：15~25 parts of potassium hydroxide, water 900~
1200 parts, 90~120 parts of gutter oil.
In such scheme, each component is calculated by weight as described in step 2)：1700~1900 parts of water, ammoniacal liquor 60~70
Part, 5~6 parts of cellulose ether.
In such scheme, the ammonia concn is 20wt%.
In such scheme, the main component of step 1) separation and recovery gained liquid is glycerine, can be refined by simple process
High-purity glycerol, it can realize that gutter oil obtains comprehensive reutilization purpose to greatest extent.
The gutter oil cement board additive prepared according to such scheme, can be used as cement foam board foam stabilizer, or general
Logical concrete waterproofer.
Gutter oil cement board additive prepared by the present invention is a kind of emulsion form foam stabilizer, have foam stabilizing efficiency high,
The features such as dosage is small, with regard to the foam stabilizing effect of calcium stearate can be reached under relatively low volume；And its dispersiveness is strong, can be greatly improved
Cement slurry mixes the uniformity put, and is advantageous to the later strength of increase gained cement board.
Gutter oil cement board additive prepared by the present invention has very good hydrophobicity, it is also possible to makees common mixed
Coagulate native waterproofing agent.
The present invention is placed under heated alkaline environment using gutter oil as raw material hydrolyzes to form higher fatty acids fat and glycerine, so
After be heated to 105~110 DEG C remove moisture removal after, by way of separation of solid and liquid, realize the separation of higher fatty acids fat and glycerine.
It is glycerine wherein to separate and collect gained waste liquid main component, passes through simple process can refining high-purity glycerine.And hydrolyze life
Into higher fatty acids fat, be a kind of mainly by the mixture that forms of higher fatty acid salt that carbon chain lengths are 16~18, by it
To after being made higher fatty acids ammonium emulsion, have than single fat hydrochlorate, aliphatic acid ammonium emulsion is stronger, more preferable foam stabilizing effect.
Compared with prior art, the beneficial effects of the present invention are：
1) present invention is prepared for a kind of gutter oil cement board additive using gutter oil, and the additive has excellent
Foam stability energy and water resistance, and the preparation method being related to is simple, has important economic benefit and environmental benefit.
2) gutter oil cement board additive prepared by the present invention has good hydrophobic performance, is also suitable for being used as commonly
Concrete waterproofer.
3) main component of gutter oil hydrolysis separation and recovery gained waste liquid is glycerine, can be produced by simple refinery practice
High-purity glycerol, the comprehensive reutilization of gutter oil, and high-efficiency cleaning can be achieved.
