Abstract
The invention provides an inorganic high-temperature resistant grouting material and a preparation method thereof, wherein the inorganic high-temperature resistant grouting material comprises the following components in parts by mass: 30-35 parts of high-temperature-resistant cement, 30-40 parts of platy corundum, 13-18 parts of quartz sand, 4-8 parts of calcium sulfate whisker, 0.10-0.15 part of water reducer, 0.01-0.06 part of defoamer, 0.01-0.06 part of plastic expansion agent, 9-14 parts of silica sol, 0.5-1.0 part of water-based graphene slurry and 3-7 parts of water. The grouting material has smooth and flat surface after solidification, does not bulge, crack or fall off powder, and can be used for a long time at a high temperature of 500 ℃.
Description
Technical Field
The invention relates to the technical field of grouting materials, in particular to an inorganic high-temperature resistant grouting material.
Background
Grouting material is injected into gaps and holes of stratum, rock or structure under the action of pressure, so as to increase bearing capacity, prevent leakage and improve the overall performance of the structure; or under the action of the self gravity of the material, the fluid material flows into the cavity or cavity of the equipment object and the electronic device to achieve the special functional requirements of filling and fixing, providing heat conduction, insulation, high temperature resistance, sealing and the like, and is formed by mixing a main agent, a solvent (water or other solvents) and an additive (curing agent, stabilizing agent and the like). The use environment of the grouting material is normal temperature. But the grouting material is also required to be used on a plurality of high-temperature devices and high-temperature equipment, and the high-temperature resistant grouting material has the functional requirements of sealing, fixing, high-temperature erosion resistance, heat conduction, insulation and the like.
The high temperature resistant grouting material can be divided into an organic high temperature resistant grouting material and an inorganic high temperature resistant grouting material, and the organic high temperature resistant grouting material has the problems of environmental protection, environmental pollution, unstable high temperature resistance, high cost and poor durability; the inorganic high-temperature resistant grouting material can avoid the problems, but has the phenomena of easy bulge, cracking, powder falling on the surface and the like after the grouting body is solidified, and the thickness of primary grouting cannot be too thick, otherwise, the phenomena of bulge, cracking, powder falling on the surface and the like are more serious when the grouting material is applied at a high temperature in practice. In particular in the high-temperature clean filtration industry, the required grouting material has technical requirements of high temperature resistance, good sealing performance (gas media such as filtered air, and the like, the grouting body cannot crack after being solidified), good cohesive strength (the surface of the grouting body cannot fall off powder after being solidified), and the grouting body cannot release small organic molecules in the use process after being solidified, and the like, and has higher requirements.
Disclosure of Invention
The invention provides an inorganic environment-friendly high-temperature-resistant grouting material capable of being poured relatively thick at one time, and the grouting material has a smooth and flat surface after being solidified, does not bulge, crack or fall powder, and can be used for a long time at a high temperature of 500 ℃.
The technical scheme adopted for achieving the purposes of the invention is as follows:
an inorganic high-temperature resistant grouting material comprises the following components in parts by mass: 30-35 parts of high-temperature-resistant cement, 30-40 parts of platy corundum, 13-18 parts of quartz sand, 4-8 parts of calcium sulfate whisker, 0.10-0.15 part of water reducer, 0.01-0.06 part of defoamer, 0.01-0.06 part of plastic expansion agent, 9-14 parts of silica sol, 0.5-1.0 part of water-based graphene slurry and 3-7 parts of water.
The high-temperature-resistant cement is one or a mixture of two of high-alumina cement and sulfur-alumina cement. The high-alumina cement is aluminate cement currently sold in the market; the sulphoaluminate cement is the sulphoaluminate cement which is currently sold in the market.
The plate-shaped corundum is obtained by mixing 21-26 parts of plate-shaped corundum with the thickness of 0.2-0.6mm and 9-14 parts of plate-shaped corundum with the thickness of 0.5-1.0 mm.
The mesh number of the quartz sand is 120-200 meshes.
The calcium sulfate whisker is columnar calcium sulfate fiber, the diameter is 1-10 mu m, and the length-diameter ratio is 5-40.
The water reducer is a powder type polycarboxylic acid high-performance water reducer.
The defoamer is a dry powder type organosilicon compound active surface auxiliary agent product used in a dry powder mortar product system.
The plastic expanding agent is bauxite type plastic expanding agent, namely yellow powder which is prepared by taking bauxite minerals as main components and grinding the bauxite minerals through surface treatment, and is universal type plastic expanding agent for dry powder mortar products.
The colloidal particle size of the silica sol is 8-15nm, the solid content is 25-35%, and the alkali resistance is good.
The aqueous graphene slurry is a pre-dispersion treated graphene aqueous slurry, and the graphene content in the slurry is 5-8%.
The invention also provides a preparation method of the inorganic high-temperature resistant grouting material, which comprises the following steps: (1) uniformly mixing plate-shaped corundum and quartz sand;
