Abstract
The invention discloses a heat-insulating board for a building curtain wall and a preparation process thereof, wherein the heat-insulating board is prepared from the following raw materials in parts by weight: 30-40 parts of silica fume, 15-30 parts of fly ash, 2.5-5 parts of azodicarbonamide, 60-80 parts of deionized water, 20-40 parts of polystyrene, 7.5-10 parts of flame retardant, 7-15 parts of light stabilizer, 100-150 parts of cement, 15-20 parts of modification reinforcing agent and 1.5-3 parts of early strength agent; this modified reinforcing agent kind contains alkoxy and connects on the silicon atom, take place condensation reaction with the active hydroxyl on silica fume surface and form Si-O-Si bond, and then increase the hardness of heated board, and contain a large amount of halogen radicals in the modified reinforcing agent molecule, hinder moisture to inside the infiltration of heated board, a large amount of hydrogen bonds make the viscosity increase of foaming granule simultaneously, van der Waals gravitation and the corresponding increase of winding degree between foaming granule macromolecule chain, and then increase the toughness of heated board, difficult emergence fracture, the life of heated board has further been increased.
Description
Technical Field
The invention belongs to the field of insulation board preparation, and particularly relates to an insulation board for a building curtain wall and a preparation process thereof.
Background
The building heat insulation and preservation is an important aspect of saving energy, improving living environment and using function, the proportion of building energy consumption in the whole human energy consumption is generally 30-40%, and most of the energy consumption is energy consumption of heating and air conditioning, so the building energy saving significance is great, the heat insulation plate is a common building heat insulation and preservation means at present, the common heat insulation plate has good heat insulation effect, but the water absorption rate of the heat insulation plate is high, after long-time use, a large amount of water is absorbed in the heat insulation plate, and the heat insulation effect of the heat insulation plate is greatly reduced;
chinese patent CN105439616A discloses a fireproof insulation board, which is prepared from the following raw materials, by weight, 100 parts of high-alumina cement, 10-20 parts of mineral stone powder, 10-20 parts of an adhesive, 20-40 parts of a flame retardant, 10-25 parts of polyphenyl particles and 10-30 parts of water, and has a good fireproof function, but the insulation board has poor water resistance, after long-time use, the insulation performance of the insulation board is reduced due to moisture in the insulation board, and meanwhile, after the insulation board is used for a period of time, the internal materials of the insulation board are loosened, so that cracking and even falling occur, and the service life of the insulation board is seriously influenced.
Disclosure of Invention
The invention aims to provide a heat-insulating plate for a building curtain wall and a preparation process thereof, wherein a modification reinforcing agent is prepared in the process of preparing the heat-insulating plate, the modification reinforcing agent contains alkoxy in the molecule, the alkoxy is connected to a silicon atom, silanol is formed after the modification reinforcing agent reacts with moisture in the air, active hydroxyl on the surface of silica fume in the heat-insulating plate is subjected to condensation reaction to form Si-O-Si bonds, so that loose particles are connected, the hardness of the heat-insulating plate is further increased, the modification reinforcing agent contains a large number of halogen groups, the hydrophobicity of the halogen groups is very high, a layer of hydrophobic film is formed on the surface of the heat-insulating plate to prevent the moisture from permeating into the heat-insulating plate, the heat-insulating moisture resistance is further enhanced, a plurality of amino groups contained on the modification reinforcing agent are easy to form hydrogen bonds, the increase the viscosity of foamed particles due to the increase of the hydrogen bonds, and the Va, and then increase the toughness of heated board, difficult emergence fracture has further increased the life of heated board.
The technical problems to be solved by the invention are as follows:
1. after the common building curtain wall insulation board is used for a long time, the insulation board can absorb rainwater and moisture in the air, so that a large amount of moisture is contained in the insulation board, the wall is easy to leak, and the insulation performance of the insulation board is seriously influenced;
2. building curtain heated board commonly used, after long-time the use, loose phenomenon appears in the heated board inner material, and then takes place the fracture and drops even for the heated board can't reach the heat preservation effect, and can't accomplish to use with building wall with the life-span.
3. In the preparation process of building curtain heated board, cutting device is used commonly, and traditional stereoplasm heated board cutting device needs the cutting that a plurality of power consumption devices could accomplish the heated board, and energy resource consumption is great, can only carry out single width or length simultaneously and cut for cutting efficiency is lower.
The purpose of the invention can be realized by the following technical scheme:
the heat-insulating board for the building curtain wall is prepared from the following raw materials in parts by weight: 30-40 parts of silica fume, 15-30 parts of fly ash, 2.5-5 parts of azodicarbonamide, 60-80 parts of deionized water, 20-40 parts of polystyrene, 7.5-10 parts of flame retardant, 7-15 parts of light stabilizer, 100-150 parts of cement, 15-20 parts of modification reinforcing agent and 1.5-3 parts of early strength agent;
