Abstract
The invention discloses a waxy separant for a precast concrete unit, belonging to the separant. The waxy separant is mainly composed of industrial solid paraffin, diesel and talcum powder in parts by weight: 90-110 parts of industrial solid paraffin, 20-30 parts of diesel and 4-6 parts of talcum powder, and the optimum parts by weight is as follows: 100 parts of industrial solid paraffin, 25 parts of diesel and 5 parts of talcum powder. The waxy separant can prevent volatilizing and drenching, does not pollute reinforcing steel bars and concrete unit surfaces, does not adsorb insets and improves demoulding effect and surface appearance quality of the precast concrete units.
Description
Technical field
The invention belongs to separant, especially relate to a kind of concrete separant.
Background technology
In the construction of highway, railway, municipal Infrastructure, often need with the prefabricated a large amount of reinforced concrete member of template, for ease of the demoulding, available coagulation soil member adopts oily separant usually, as adopt machine oil or machine oil+diesel oil or edible oil, as the patent of invention " concrete parting agent and preparation technology thereof " of publication number CN1064698A, its releasing agent is the aqueous formulation that is mixed with by mold oil, regeneration machine oil or used oil, food plant oil foot soap, water; This oil separant part that comes with some shortcomings, high temperature is volatile, drench with rain and easily wash away, easily pollute easy absorption insect of reinforced concrete member and night in summer, all can influence the stripping result and the visual appearance of concrete prefabricated element.
Summary of the invention
The purpose of this invention is to provide a kind of Waxy separant for precast concrete unit, can volatilization prevention, anti-rain, do not pollute reinforcing bar and surface of concrete structure, do not adsorb insect, improve the stripping result and the surperficial impression quality of precast concrete.
The object of the present invention is achieved like this: a kind of Waxy separant for precast concrete unit, mainly form by industrial solid paraffin, diesel oil and talcum powder, the proportioning by weight ratio, its share is: 90～110 parts in industrial solid paraffin, 20～30 parts of diesel oil, 4～6 parts of talcum powder; Its optimum weight proportioning share is: 100 parts in industrial solid paraffin, 25 parts of diesel oil, 5 parts of talcum powder.
Paraffin is the popular name of solid-state higher alkane mixture, and molecular formula is CnH2n+2, wherein n=20-40.Paraffin is the waxy solid of white, colorless and odorless normally, and fusing point is at 47 ℃-64 ℃, the about 0.9g/cm of density
3It is water insoluble, but dissolves in ether, benzene and some ester.Paraffin not with the reaction of common chemical reagent, but can burn.
The purposes of paraffin is very extensive, and paper is immersed the various paraffin paper that just can produce good water resistance behind the paraffin, can be used for packing, metal rust preventing and press such as food, medicine; Paraffin can make textiles softness, smooth and flexible after adding cotton yarn; Paraffin can also make washing composition, emulsifying agent, dispersion agent, softening agent, lubricating grease and wait most.
This wax separant normal temperature for solid-state, slightly is creamy white down, and is sub-translucent, about 50 ℃ of fusing points.
During use, earlier industrial solid paraffin is placed on iron pan internal heating to 70 ℃-80 ℃ by share, be melted into liquid state, the diesel oil and the talcum powder that add corresponding share then, under 70 ℃ of-80 ℃ of situations of insulation, stirring is gluey, should evenly brush on the template of precast concrete by glue wax releasing agent with cylinder when hot, thickness is 2mm, and after the cooling, this wax releasing agent forms the sealing coat that a bed thickness is the solid wax shape of 2mm on template.This sealing coat volatilization prevention, anti-rain does not pollute surface of concrete structure, does not adsorb insect, the easily demoulding, the surface quality of concrete member is good.
The Waxy separant for precast concrete unit that the present invention proposes, safety easy to use, stripping result is good, improves the surface quality of concrete prefabricated element.
Now in conjunction with the embodiments Waxy separant for precast concrete unit proposed by the invention is further described.
