Abstract
The invention provides novel magnesium-phosphorus adhesive. The adhesive is prepared from, by weight, 18-42% of calcium silicate or metakaolin or coal ash, 12-28% of magnesium oxide, 24-46% of potassium monophosphate and 22-40% of granite stone sand or granite. The grindable magnesium-phosphorus adhesive is comparatively short in hardening time and curing time, high in heat resistance, moisture resistance, early-stage compression strength, tensile strength and bending strength and higher in salt corrosion resistance compared with existing cement and can be used to a wide-range environmental temperature without losing other properties. The adhesive can be matched with or replace the existing cement to be used. Hardening time and curing time can be controlled by using cold water or boric acid as an additive.
Description
Technical field
The invention belongs to technical field of adhesive, relate to a kind of magnesium phosphorus new adhesive.
Background technology
Our national construction site now, selected cement, it is water, the mixture of unslaked lime and silicon oxide, and its is economical, easily uses at the scene.But it has some shortcomings, source material has unstable quality usually, and have high viscosity, this is disadvantageous, especially to pumping or spraying.Existing cement is vulnerable to the impact of ambient temperature, and slaking is slow, and because existing cement pH value is high, also damages exposed skin.
Summary of the invention
The object of this invention is to provide a kind of magnesium phosphorus new adhesive, substitute cement, solve the problem that quality is unstable, set time is slow existed in prior art.
The technical solution adopted in the present invention is, magnesium phosphorus new adhesive, its component is 18% to 42% Calucium Silicate powder by weight percentage, metakaolin or flyash, the magnesium oxide of 12% to 28%, the monophosphate potassium of 24% to 46% and the grouan stone sand of 22% to 40% or grouan.
Magnesium phosphorus new adhesive of the present invention has relatively short sclerosis and set time, it is highly heat-resistant, there is higher wet fastness, there is high early stage tensile strength, tensile strength and flexural strength, compare existing cement, has higher resistance brine corrosion performance, be used in the envrionment temperature of wide region, other character can not be lost.Can with existing cement with the use of, also can substitute existing cement use.Sclerosis and set time can by using cold water or boric acid as additive, the period.
Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
First part:
The technical solution adopted in the present invention is, magnesium phosphorus new adhesive, its component is 18% to 42% Calucium Silicate powder by weight percentage, metakaolin or flyash, the magnesium oxide of 12% to 28%, the monophosphate potassium of 24% to 46% and the grouan stone sand of 22% to 40% or grouan.
During such scheme mixing, by making acid phosphoric acid ester enough solvable to drive top efficiency to react.Therefore, dry mixture needs effectively soaked and need enough shearing forces, to dissolve monophosphate potassium.This is the dry substance by physical mixed, uses high-shear, adds water and come in high speed drill or other high shear mixing system.
Second section:
The present invention chooses grouan stone sand or grouan as aggregate, and reason, after magnesium oxide and the mixing of monophosphate potassium, creates one and be covalently bound to granite aggregate, obtain granitic intensity, strengthen the intensity of magnesium phosphorus new adhesive.
If silica sand is used as aggregate, magnesium phosphorus new adhesive is non-caked or adhere to sand but encapsulate every granule, therefore produces space, reduces strength property.
Part III:
Table one is that the present invention mixes by different ratios with sand, required set time and strength property table.Table two mixes by different ratios with grouan for the present invention, required set time and strength property table.
