Abstract
The invention discloses a kind of lightweight heat-proof metallurgy of nickel waste residue foamed ceramicses and preparation method thereof, including basic ceramic raw material, curing agent and foams；Wherein, basic ceramic raw material includes nickel slag, high alumina cement, kaolin, calgon and water, and foams include foaming agent, foam stabilizer and water；After nickel slag, high alumina cement, kaolin, calgon and the water after magnetic separation are first carried out ball mill mixing when preparation, slurry is made, then foaming agent, foam stabilizer and water are mixed, foams are made, finally slurry, foams and curing agent are mixed, demoulded, is dry, foamed ceramics is made after calcining.Not only pore size is close for foamed ceramics of the invention, is evenly distributed, and density is low, and compressive property is high, and thermal coefficient is small, and then thermal insulation property is good；While preparation method is simple, energy conservation and environmental protection, it being capable of industrial applications.
Description
Technical field
The invention belongs to field of ceramic preparation more particularly to a kind of lightweight heat-proof metallurgy of nickel waste residue foamed ceramics and its preparations
Method.
Background technique
Foamed ceramics is the porous ceramic film material of three-dimensional structure, and the foamed ceramics porosity is high, intensity is high, sound isolating and heat insulating performance
Good, stable chemical performance, is widely used in the fields such as metallurgy, space flight, automobile, can be used as heat-insulated, insulation, catalyst carrier,
Filter etc., application prospect is very wide.
There are many technique for preparing foamed ceramics, mainly there is addition pore creating material, foam process, Polymeric sponge method, colloidal sol
Gel method, extrusion molding etc..Wherein foam process, addition pore creating material are using relatively broad.Foam process refers to addition foaming agent
Bubble is generated using mechanical foaming or high temperature sintering, obtain porous structure and then obtains foamed ceramics.Currently, high temperature foamed
The Air Bubble Size that generates in journey, shape, distribution are difficult to control, and foaming at normal temp technique is widely applied.
Patent CN102838379A discloses a kind of light floamed ceramic and preparation method thereof, passes through addition surfactant
Foam is made in foaming in advance, then mixes with prefabricated slurry, and light floamed ceramic is made.But foamed ceramics made from the patent is thermally conductive
Coefficient > 0.05W/ (mK), thermal coefficient is larger.Patent CN105601320A discloses a kind of utilization rich magnesium metallurgy nickel slag preparation
Porous ceramics and preparation method thereof, pore-creating is carried out by addition starch, active carbon, obtains advantages of higher compressive strength and counter-bending strong
The porous ceramics of degree, but density is bigger, is greater than 1500kg/m3, porosity is lower, less than 50%.
Summary of the invention
Goal of the invention: the first object of the present invention is to provide that a kind of pore size is close, be evenly distributed, density is low, and leads
The small lightweight heat-proof metallurgy of nickel waste residue foamed ceramics of hot coefficient；
The second object of the present invention is to provide the method for the preparation of the ceramics.
Technical solution: lightweight heat-proof metallurgy of nickel waste residue foamed ceramics of the invention includes the following raw material: base in parts by weight
70~85 parts of plinth ceramic raw material, 1~5 part of curing agent and 14~25 parts of foams；
Wherein, basic ceramic raw material includes the following raw material in parts by weight: 45~55 parts of nickel slag, high alumina cement 15~20
Part, 10~15 parts of kaolin, 0.5~1 part of calgon and 15~20 parts of water；
Foams include the following raw material in parts by weight: 10.2~15.8 parts of foaming agent, 0.5~1.5 part of foam stabilizer and water
82.7~89.3 parts.
Furtherly, the foaming agent that the present invention uses includes mass ratio for the surfactant of 0.025~0.5:1 and egg
Clearly.Wherein, surfactant preferably can be lauryl sodium sulfate, monoester phthalic acid fatty alcohol sodium, fatty alcohol polyoxy second
Alkene ether sodium sulfate, fatty alcohol polyoxyethylene ether (3) sulfosuccinic acid monoesters disodium, myristic acid sodium or fatty acid amide sulfosuccinate
Monoester disodium salt.
The present invention prepares ceramic material by using nickel slag, and in the feed further using by surfactant and egg
The foaming agent being composed clearly passes through the original of Orqanics Monomer so that protein is denaturalized in egg white during the preparation process
Position polymerization promotes slurry curing, enhances intensity, and egg white surface tension is small, the more reactive hydrogen contained can effectively subtract
Few water evaporation, improves Stability of Slurry；Meanwhile toxic gas will not be generated during the preparation process, it is environmentally friendly.
It further says, the curing agent that the present invention uses can be poly-vinyl alcohol solution, silica solution, polyvinyl butyral second
Alcoholic solution or diethylenetriamine.Foam stabilizer can be hydroxyethyl starch, polyacrylamide, laruyl alcohol, Span 80, calcium stearate or rouge
Fat acid.The specific surface area of the nickel slag used is 700~800m2/ kg, wherein MgSiO3And Mg2SiO4Content be not less than 85%.
The method that the present invention prepares lightweight heat-proof metallurgy of nickel waste residue foamed ceramics, includes the following steps:
(1) in parts by weight by nickel slag, high alumina cement, kaolin, calgon and 15~20 parts of the water after magnetic separation
After carrying out ball mill mixing, slurry is made；
(2) foaming agent, foam stabilizer and 82.7~89.3 parts of water are mixed in parts by weight, foams is made；
