Material granule, in convertible hybrid reactor, heat-insulated cellular material particle is heated to 90 degree, dispersible rubber powder and silica
Powder is uniformly mixed, fusing, and the mixture of molten condition is sprayed at heat-insulated cellular material particle surface, overturning mixing 25-30
Minute, heat-insulated cellular material is obtained, every heat-insulated cellular material particle of 100 parts by weight adds the dispersible rubber powder of 5 parts by weight and 2 weight
Part silicon dioxide powder.
Preferably：The thickener is any one or a few of chitosan, sodium alginate and agar.
Preferably：The cured temperature is 160 DEG C~200 DEG C, and the cured time is 1h~2h；The temperature of the carbonization
It it is 600 DEG C~800 DEG C, the time of carbonization is 2h~3h.
Preferably：The cracking resistance auxiliary agent is the polypropylene anti-crack fiber that length is 1~10mm.
A kind of preparation method of honeycomb vitrified microsphere building heat-insulating material of the present invention includes the following steps：
（1）Glass bead, heat-insulated cellular material, cement, re-dispersible glue powder, hydroxypropyl methyl fiber are weighed according to the proportioning
Element, organosilicon moisture repellent, cracking resistance auxiliary agent, kaolin powder, talcum powder, which are put into blender, to be mixed and stirred for uniformly；
（2）Water is added into said mixture, ratio of water to material is 0.40~0.55:1, continue 30~60min of stirring with blender；
（3）Above-mentioned slurry is poured into and uses press-forming machine compression moulding in mold, natural curing 48h is to get the honeycomb glass
Change microsphere building heat-insulating material.
Preferably：The pressure of the compression moulding is set as 0.80~0.85MPa, and the pressing time of the compression moulding sets
It is set to 20~60min.
Beneficial effects of the present invention：
The present invention uses heat-insulated cellular material for filler, 80~120mg/cm of density of heat-insulated cellular material3, mechanical property is excellent
Good, intensity is high, and overall structure is stablized, and foam is uniform in bee-hole, and rate of closed hole is high, and thermal coefficient is small, reduces heat radiation, and heat passes
It leads and cross-ventilation, improves heat insulation and preservation effect.
Glass bead has excellent heat preservation adiabatic and fire protecting performance, suitably changes the proportioning of each component in the material, makes
Have low thermal conductivity, high compression-strength, it is not easy to crack, deformation the advantages that.Inorganic heat preserving aggregate glass bead is hollow ball
Structure, and heat-insulated cellular material is also hollow-core construction, therefore keep porosity big there are countless miniature spherical closed pores in thermal insulation material
Big to increase, integral wall density is low, and heat insulation effect is good.
Re-dispersible glue powder is that the 5010N vinyl acetate/ethylenes of Wa Ke companies of Germany are copolymerized（EVA）Rubber powder can divide again
It is because one layer of hydrophilic polyvinyl alcohol colloid has been wrapped up on its surface in production that scattered rubber powder, which is dissolved in water, and main chain contains largely
Nonpolar segment（Show as hydrophobicity）, and side chain contains polar group（Hydrophily）Acetate groups（-OCCH3）, thus make
Re-dispersible glue powder is dissolved in the emulsion particle surface formed after water and contains-OH ,-OCCH3 isopolarity group, dredging in EVA main chains
Water base group's nonpolarity（It is hydrophobic）Segment.There is layer of polyethylene alcohol to make rubber powder shape after being added to the water on re-dispersible glue powder surface
At polymer emulsion, it is evenly distributed in inorganic matrix.Rubber powder granule, which is distributed between inorganic matrix, also has lubricating action, together
When improve the air content of inorganic slurry.With progress, the moisture evaporation etc. of inorganic coagulation material hydration reaction, emulsion particle phase
Mutually close, fusion, gradual dehydration form polymer membrane, are protected since the polyvinyl alcohol on emulsion particle surface etc. is water-soluble
Glue is saponified under alkaline condition, and after polyvinyl alcohol is separated, this floor height molecular film of formation is not soluble in water, is provided with preferably
It is resistance to.Aqueous glued membrane forms reticular structure between being distributed in cementitious material hydrated product, thus in cured complex heat-preservation
The flexible polymeric film that the brittle property skeleton being made of hydraulicity inorganic material and rubber powder are formed in gap is formd in material
Compound system so that the cohesive force of compound insulating material is improved.And the tensile strength of the macromolecule membrane of rubber powder formation
It is the decades of times of hydraulic material, the anti-crack ability of deformability higher, thermal insulation material is also improved.
Polypropylene fibre random distribution between inorganic matrix forms 3 D stereo reticular structure, since polypropylene fibre has
Very high tensile strength, this stereochemical structure have good stretching mechanism.And in the hydraulic cementing materials aquation mistake such as cement
Cheng Zhong easily causes contraction distortion due to dry contraction, temperature shrinkage, chemical shrinkage and the brittleness of itself etc., this
Contraction is easy to cause material internal and cracks.The stereochemical structure that polypropylene fibre latter aspect is formed, which is added, can prevent small
Grain sinks, and on the other hand, polypropylene fibre diameter reaches micron level, and fiber spacing is smaller, the interlaced formation of fiber
Structure with stretching mechanism can slow down the crack of inorganic matrix generation, alleviate the Emergence and Development in crack, avoid through slight crack
It is formed.
The hydrophober of selection is organosilicon moisture repellent, and active constituent is siloxanes, including multiple silicone units, it can be molten
Organic siliconresin structure is formed in most of solvents.The active constituent siloxanes of organosilicon moisture repellent has preferable permeability,
Be conducive to absorb the volatilization of moisture in matrix.Siloxanes in organosilicon moisture repellent reacts dealcoholysis life with water in concrete surface
At silanol, silanol is further formed silicones structure.Alkaline resistance properties is more preferable when alkyl chain is longer in silicones structure, more
Water-proof function is played suitable for the inorganic coagulation material system in alkalinity.Reactive group-H ,-OH in organic siliconresin etc. can
It is combined with the water of polar group-OH with inorganic matrix surface etc. or matrix surface, condensation may be played and form primary bond
Or hydrogen bond, it is also possible to which dipole attracts each other, and this chemisorption power is very strong.Make inorganic matrix surface shape in this way
At one layer of organic siliconresin, end carries Si-R bases, and the Si-O ,-CH3 on silane resin chain show as hydrophobicity, these
Hydrophobic group arranges so as to form one layer of hydrophobic film outward.It is attached to hating for inorganic matrix surface by hydrogen bond or chemical bond
Water film surface tension is relatively low, inorganic matrix surface is can be uniformly distributed in, while this layer of hydrophobic film plays resistance impermeable role
The discrepancy of gas will not be obstructed.Thus allow thermal insulation material keep blocking water for a long time, and does not influence to absorb the steaming of moisture
Hair.
The honeycomb vitrified microsphere building heat-insulating material of the present invention is with density is small, compression strength is big, thermal coefficient is low, heat preservation
The advantages that effect is good, and fire-protection rating is A grades, is a kind of fireproof and heat-insulating material of high comprehensive performance.
