Background
The glass pumice is used as a novel light environment-friendly material, and has a micropore structure which not only has water permeating and water storing capabilities, but also has heat insulating and preserving capabilities. Therefore, the composite material can be applied to municipal pavements, and can also be used as a building material to be applied to bridge and house construction.
When the glass pumice is applied to pavement, the porosity is 15-25%, the water permeating speed is high, the burden of urban drainage facilities can be reduced when the water is concentrated, and the water accumulation on the pavement is prevented. Particularly, in recent years, with the occurrence of urban waterlogging and other problems, a sponge city design concept is provided, and by combining a gap structure between glass pumice and a micro-pore structure of the glass pumice, and applying the glass pumice in a large amount, a sponge city with functions of seepage, stagnation, storage, purification, use, discharge and the like can be built so as to effectively solve the urban waterlogging phenomenon. Therefore, the glass pumice is used as a filler for road paving in various places, the conventional glass pumice can meet the bearing requirement of a common road surface, but the strength of the conventional glass pumice cannot meet the requirement of special road sections needing to pass large heavy-duty engineering vehicles, and therefore the strength of the glass pumice needs to be improved.
When the glass pumice is applied to bridges and houses, the glass pumice is applied as an interlayer, and the effects of reducing weight, improving bearing capacity and saving energy and heat can be realized by utilizing the light weight and the micropore structure of the glass pumice, but the glass pumice is also required to have higher strength to realize the performance which is not lost in conventional building materials due to the same safety consideration, and a better heat insulation effect is also required for the application of wall building materials.
In view of the above, a preparation method capable of improving the strength and the heat preservation performance of the glass pumice is needed.

Detailed Description
The invention relates to a high-strength closed-pore glass pumice, which is particles formed by sintering powder, wherein the powder comprises silicon dioxide powder (the particle size is 60-80 microns) and carbonate powder (the particle size is less than 60 microns), bubbles or pores which are not communicated with the outside and are in a closed structure form are generated in the particles, the bubbles or pores are communicated or closed with each other, and part of the bubbles or pores which are communicated with the outside are also arranged in the particles.
The high-strength closed-pore glass pumice can be obtained by the following two typical proportions and implementation processes.
The first embodiment is as follows:
the invention relates to a preparation method of high-strength closed-cell type glass pumice,
s1, mixing materials: putting the raw materials into a stirrer, and stirring and mixing uniformly;
the weight ratio of the raw materials is as follows:
90% of glass powder;
5% of marble powder;
5% of limestone;
s2, feeding: in order to ensure the adverse effect caused by the existence of large-particle raw materials in the process of forming closed pores, a vibrating screen is used for screening, namely the mixed raw materials in the step S1 are introduced into the vibrating screen for screening, and the screen mesh is 300 meshes; the vibrating screen is positioned above the feeding end of the conveying belt of the sintering furnace, two isolating strips vertical to the running direction of the conveying belt are arranged on the conveying belt, the height of each isolating strip is 20mm, a blocking strip is arranged at the feeding port of the sintering furnace and is vertical to the running direction of the conveying belt, the bottom of each blocking strip is in sliding contact with the corresponding isolating strip (namely the ground clearance of the bottom of each blocking strip is equal to the ground clearance of the top of each isolating strip), the screened raw materials in the vibrating screen enter the conveying belt, and the stacking height of the raw materials is not higher than 20mm through the cooperation of the isolating strips and the blocking strips when the raw materials enter the sintering furnace along with the conveying belt;
meanwhile, a material collecting box (the width of the material collecting box is larger than that of the conveying belt) is arranged below the feeding end of the conveying belt, and the bottom of the material collecting box is communicated with the stirrer in the S1 as a material lifting mechanism through a screw conveyor, so that raw materials swept to the two sides of the conveying belt through the barrier strips can be recycled
S3, sintering: sequentially passing through a preheating temperature rising area, a foaming sintering area and an annealing area in a sintering furnace to obtain the glass pumice with the closed pore structure;
wherein the temperature of the preheating temperature rising region is 780 ℃ and the duration time is 30 min;
the temperature of the foaming sintering area is 800 +/-5 ℃, and the duration time is 10 min;
the temperature of the annealing zone is 600 ℃ and the duration time is 20 min;
compared with the conventional process flows of a preheating zone, a heating zone and a foaming sintering zone, the process flow integrates and improves the temperature and time of the preheating heating zone, and glass powder starts to melt at 790-800 ℃, so that the temperature and time of the preheating heating zone are improved, the glass powder can be in a high-temperature street state before the melting starts, and then the glass powder is in a 10 ℃ melting state for a short time in the foaming sintering zone, so that carbon dioxide bubbles generated in calcium magnesium carbonate in a short time are not broken in time, a large number of closed cell structures are formed, the process flow of the annealing zone is increased later, the purpose of avoiding the phenomenon that the irregular breakage of glass pumice causes the local cracking of the closed cell structures to form open cell structures due to the fact that the direct air cooling temperature is reduced violently in the past is avoided, and the occupation ratio of the closed cell structures can be effectively increased by reducing the temperature change through the annealing process;
preferably, a secondary annealing area is arranged behind the annealing area, the temperature of the annealing area is 500 ℃, the duration time is 15-20 min, and the intensity of temperature change is further reduced, so that the closed pore structure of the closed pore glass pumice is firmer.
S4, cooling: and spreading the sintered glass pumice on a cooling table and cooling to room temperature.
The compressive strength of the glass pumice prepared by the process can reach two to four times of that of an open pore structure through test detection, so that the compressive capacity of the glass pumice is greatly improved, and the glass pumice has higher bearing capacity when being applied to paving pavements and building materials; meanwhile, the closed pore structure further improves the heat-insulating capacity of the wall, and is favorable for the wall to have better heat-insulating effect when being used as a wall heat-insulating layer. The test detection is as follows: the closed-cell glass pumice prepared by the process has the strength of J1 being 1MP (namely 10 kilograms per square centimeter), the strength of J2 being 3MP and the strength of J3 being 5MP (the hardness is close to that of red bricks, and the red bricks are 7 and 5MP), so that the closed-cell glass pumice can perfectly replace conventional building materials and has the functions of light weight and heat preservation.
