Abstract

The present invention relates to a kind of prestressing force PHC tubular pile concrete parting agent specials, it is characterised in that the mass percent that its raw material components and each component account for raw material total amount is respectively：Epoxidized soybean oil 45%~58%, hydrophilic colloid compound 0.01%~0.05%, alkyl phosphonic acid complexing agent 3%~5%, organic carboxylate 0.01%~0.2%, oleate 10%~15%, water 25%~38%.The present invention can significantly improve the appearance of tubular pile concrete cement products, make the smooth bubble-free in its surface, and demoulding efficiency is high, be a kind of PHC tubular pile concretes parting agent special, can be diluted with water 8~12 times of use, with low cost, stable performances afterwards.

Description

A kind of prestressing force PHC tubular pile concrete parting agent specials
Technical field
The present invention relates to concrete admixture application field, and in particular to a kind of prestressing force PHC tubular pile concretes are special de- Mould agent.
Background technology
Prestressing force PHC tubular pile concretes are the moulding process using high speed centrifugation dehydration in a kind of forming process, by normal After pressure is steam-cured, carry out the demoulding, then a kind of hollow cylinder in HTHP steam-cured " secondary maintenance " uiform section coagulation Native component.During the adverse circumstances such as PHC pile tubes Yu Haiyang, cold, saline and alkaline, the big temperature difference, the durability to pile tube is particularly tested, its Durability is closely related with material system, maintaining process, demoulding requirement etc..Wherein, the demoulding requirement smooth pore-free in surface, selection Suitable releasing agent can deterioration uneven to hydrated product and pore structure causes later strength reduction, durability is affected Problem play a role in improving.
Pure oils releasing agent (mineral oil, animal oil or vegetable oil etc.) is generally used, but it only makes concrete and mould Smoothly separate effect, it is difficult to improve the situation of concrete surface hornet's nest.It is a kind of mixed disclosed in publication number CN103409218 A Solidifying soil release agent and preparation method thereof, is with lard, rosin, NaOH, emulsifying agent, tributyl phosphate, formaldehyde, dodecyl Glycine betaine and appropriate organo montmorillonite are prepared from aqueous, and the method needs saponification, technique bar at 95~105 DEG C Part is harsh, and contains formaldehyde, is unfavorable for environmental requirement.A kind of environment-friendly type concrete structure disclosed in publication number CN 103789074B Part releasing agent and preparation method thereof, is prepared with raw materials such as ester oil class mould oil, interface interleaving agent, emulsifying agent, defoamers Water-based emulsion releasing agent is planted, with biological degradability, 2~8 times can be diluted and used.
The content of the invention
A kind of prestressing force PHC tubular pile concretes are provided the invention aims to improve the deficiencies in the prior art special Releasing agent, uses special releasing agent, using the low surface of releasing agent on the precast-concrete form of PHC concrete water mud products The effect of tension force, low viscosity and elimination interior formwork, so that prestressing force PHC tubular pile concrete surface textures reach face Color is consistent, flat appearance, smooth imperforate purpose.
The technical scheme is that：A kind of prestressing force PHC tubular pile concrete parting agent specials, it is characterised in that its raw material The mass percent that component and each component account for raw material total amount is respectively：
It is preferred that above-mentioned hydrophilic colloid compound is Arabic gum or agar.It is preferred that above-mentioned alkyl phosphonic acid complexing agent is 1- Dodecyl phosphonic acid or di-n-octyl phosphonic acids.
It is preferred that above-mentioned organic carboxylate is sodium formate, sodium acetate or sodium oxalate.It is preferred that above-mentioned oleate is three oil Acid glyceride, glycerine oleic acid ester or glycerin mono-fatty acid ester.
Each raw material that will be weighed is placed in agitator and is well mixed, and obtains final product a kind of prestressing force PHC tubular pile concretes special de- Mould agent.
Beneficial effect：
The present invention chooses hydrophilic colloid compound, and unique macromolecule network shape structure is effective by alkyl phosphoric acid complexing agent Win over by any means in releasing agent system, can concrete surface formed adsorption layer, with concrete in silica form hydrophilic suction Complexing agent in attached releasing network, accelerates concrete uniformity aquation, forms fine and close adsorbed film.Epoxidized soybean oil and oleic acid Ester has strong water-soluble, can enhance its paintability and greasy property so that the demoulding easily easily, is also largely eliminated The bubble of concrete surface, improves the appearance of prestressing force PHC tubular pile concrete cement products, significantly increases its later stage anti- Compressive Strength and endurance quality.Be not in lamination, 8~12 times can be diluted with water and used, preparation process is simple, environmental protection are without dirt Dye, has resistance rust effect to steel template, and suitable large-scale promotion is used.
