Description
Technical field
The present invention relates to industrial waste residue resource and utilize field, be specifically related to a kind of Foamed Nickel scum geo-polymer and preparation method thereof.
Background technology
Smelting ferronickel from red soil nickel ore waste residue (being called for short ferronickel slag) is extracting metals nickel or a kind of granulated slag that the discarded object of discharge is formed after cold water shrend in dilval smelting process.According to statistics, within 2013, China's ferronickel whole year yield reaches 710,000 tons, and the ferronickel slag supervened is more than 45,000,000 tons.By 2015, the total release of ferronickel slag was close to 100,000,000 tons.At present, ferronickel slag is made a low multiple use by China, and its processing mode is many stores up based on outdoor or fill, and not only causes the waste of resource, and takies a large amount of soil.Therefore, seek the technological approaches of a kind of economical rationality and correctly dispose and comprehensively utilize ferronickel slag, not only the healthy and sustainable development keeping stainless steel industry and nickel industry is had important strategic importance, and the alleviation of environmental pressure is also had and is of great significance.
Geo-polymer (Geopolymer) is that French scientist Davidovits utilizes active low calcium Si-Al material and high-alkali solution reaction, a kind of novel inorganic Binder Materials with high molecular polymer structure researched and developed first in 1978, this kind of material had both had the premium properties of the materials such as organic polymer, pottery, cement, many with the industrial solid castoffs such as flyash, blast-furnace cinder, slag, metakaolin or natural silicon aluminium acid salt mineral as primary raw material again, technique is simple, energy-conserving and environment-protective.Foaming geo-polymer refers to the expanded material prepared with geology polymer material as matrix or by geo-polymer method, uniform pore diameter, and curing rate is fast, intensity is high, good endurance, production efficiency is high, is a kind of fire prevention, durable, the geo-polymer expanded material of thermal insulation.Meanwhile, foaming geo-polymer is with solid waste as primary raw material, and preparation technology is simple, low cost, is conducive to economizing on resources, the energy and protection environment.
Summary of the invention
The purpose of the present invention essentially consists in, the problem big for China's ferronickel slag discharge capacity, utilization rate is low, big for environment pollution, provide a kind of Foamed Nickel scum geology polymer material, have low cost, technique is simple, consumption is big, the feature of nontoxic pollution-free, is the effective way realizing ferronickel slag recycling.
Another object of the present invention is to, it is provided that the preparation method of this Foamed Nickel scum geology polymer material.
It is an object of the invention to be achieved through the following technical solutions:
A kind of Foamed Nickel scum geo-polymer, is made up of the component of following parts by weight: ferronickel slag 100 parts, alkali-activator 5-20 part, foaming agent 0.1-1.5 part, water 20-40 part.
Described alkali-activator is made up of the component of following parts by weight: waterglass 100 parts, hydrotalcite 0.1-1.0 part, sodium abietate 0.1-1.0 part, sodium sulfate of polyethenoxy ether of fatty alcohol 0.1-1.0 part.
