Abstract
It take zeolite as high-intensity foam glass of preparing of pore-forming material and preparation method thereof that the present invention discloses a kind of.By base-material waste glass powder, zeolite, fusing assistant, suds-stabilizing agent by certain composition batching, the raw material prepared is put into ball mill for dry grinding, then granulation, compression moulding, then heat-treat at 750 DEG C ~ 900 DEG C, finally obtained high-intensity foam glass material.The present invention directly utilizes the gas that adsorbs in zeolite cavity and moisture discharge in heat treatment process and form a large amount of pore in glass, utilizes residual fibrous zeolite grain reinforcing glass matrix simultaneously.The present invention has that preparation technology is simple, firing temperature is low, multicellular glass intensity high.
Description
Technical field
The present invention relates to ceramic materials preparation technology field, being specifically related to a kind of take zeolite as high-intensity foam glass of preparing of pore-forming material and preparation method thereof.
Background technology
Multicellular glass not only has heat insulation, sound-absorbing, does not burn, does not go mouldy, without putrefaction, airtight, the advantage such as do not absorb water, but also has the features such as chemical stability is good, cold-hot impact.Because multicellular glass is durable in use, safe and reliable, therefore it in fields such as low thermal isolation, tidal defense engineering, sqouynd absorption lowering noises in occupation of more and more consequence.Abroad, multicellular glass also extensively replaces cement, iron and steel and the reinforcement of concrete outside buildings, on inner wall, and its object is exactly the shockwave absorbed because blast or earthquake produce.But generally common multicellular glass intensity is not high, this just greatly limit its building etc. in application.The multicellular glass mountain of exploitation high strength has become the study hotspot of multicellular glass.The kind of foam glass product both domestic and external is a lot, and mostly the raw material of employing is that discarded container glass, sheet glass, trade waste are as slag etc., also have and adopt natural mineral as mica, perlite, pumice sand, volcanic ash etc.Prepare with these raw materials that high performance multicellular glass can be salvaged, reduces costs, protection of the environment, there is very large economic and social benefit.
The domestic and international pore-forming material for the preparation of multicellular glass can be divided into oxidation-reduction type pore-forming material Sum decomposition type pore-forming material two class at present: oxidation-reduction type pore-forming material mainly contains carbon black, silicon carbide, graphite etc., the decomposition temperature of these pore-forming materials is often poor with the matching of general glass powder base-material initial melting temperature, rare to desirable product; Decomposition type pore-forming material mainly contains carbonate, vitriol, nitrate, organism, hydrogen peroxide etc., but because the effect of pore-forming material self-characteristic and degradation production easily makes the bubble wall thickness of obtained multicellular glass thin uneven, easy formation connectivity structure, thus the multicellular glass intensity prepared with these traditional pore-forming materials is general not high, is difficult to the requirement meeting building field.
Zeolite Rock quite enriches at the storage of China, and spread all over the country 20 Duo Ge provinces and cities and autonomous regions, is filled with cavity and duct, there are air inclusions in the space grid structure due to it, can play the effect of pore-forming material under the condition of heating.At present, take zeolite as pore-forming material, waste glass powder is base-material, and the method being prepared multicellular glass by powder sintered foam process not yet has report.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of technique is simple, raw materials cost is low, product strength is high take zeolite as high-intensity foam glass of preparing of pore-forming material and preparation method thereof.
For solving above technical problem, technical scheme of the present invention is: a kind of take zeolite as high-intensity foam glass prepared by pore-forming material, it is characterized in that: take waste glass powder as base-material, take zeolite as pore-forming material, introduce fusing assistant and suds-stabilizing agent again, they are put into ball mill for dry grinding, then granulation, compression moulding, heat-treat again, finally obtained high-intensity foam glass.
Described fusing assistant is Sodium Silicofluoride, borax one wherein.
Described fusing assistant is borax.
Described suds-stabilizing agent is tertiary sodium phosphate, ferric oxide, antimonous oxide one wherein.
Described suds-stabilizing agent is tertiary sodium phosphate.
The folding strength > 2.5MPa of described high-intensity foam glass, volume density≤0.7g/cm
3.
The preparation method of above-mentioned high-intensity foam glass, is characterized in that comprising the following steps:
1. base-material waste glass powder, zeolite, fusing assistant, suds-stabilizing agent are prepared burden by certain formula, then put into ball mill for dry grinding;
2. the batching after ball milling through granulation, then uses press dry-pressing formed;
3. the sample suppressed is heat-treated, finally cuts, obtained high-intensity foam glass material of polishing.
The formula of described batching is waste glass powder 60wt% ~ 90wt%, zeolite 10wt% ~ 40wt%, additional fusing assistant 3wt% ~ 8wt%, additional suds-stabilizing agent 1wt% ~ 5wt%.
Described dry-pressing formed pressure is 4MPa ~ 15MPa.
Described heat treating regime is: temperature rise rate is 5 DEG C/and min ~ 15 DEG C/min, thermal treatment temp is 750 DEG C ~ 900 DEG C, and soaking time is 20min ~ 120min.
Oxidation-reduction type pore-forming material Sum decomposition type pore-forming material (as flyash, calcium carbonate, sodium carbonate etc.) that abandoning tradition of the present invention is generally applied, directly utilizes a large amount of air inclusions held in zeolite rack-like structure to overflow and pore-forming in heat-processed innovatively; Also utilize the fibrous zeolite grain reinforcing glass matrix remained in multicellular glass simultaneously.Preparation technology of the present invention is simple, and firing temperature is low, and prepared multicellular glass not only pore is even, and volume density is little, but also has the advantage of high strength.
