Summary of the invention
The present invention overcomes the existing in prior technology powder to hold technical problems such as ability, the dry density of wrapping up in granules of polystyrene are big, suction is big, thermal conductivity is low under the arm, providing a kind of is gelling material with cement, penetrant crystalline is as the waterproof auxiliary agent, and expansible black lead is the preparation method of a kind of adhesive polystyrene ethene granule insulating material of enhancing fire retardant material.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: hydrophobic fireproof heat-insulating material is divided into and is A, B two components, and the A component is a powder material, the polystyrene plastic particle of B component for handling through gel.
The main component of A component is to be main gelling material with cement, and flyash, grey calcium powder are second gelling material, with glass fibre, expansible black lead, penetrant crystalline is composite additive, its proportioning is (weight proportion): in parts by weight, get cement 30~50, flyash 20~45, ash calcium powder 5~20, glass fibre 0.05~2, expansible black lead 0.05~0.85, penetrant crystalline 0.05~0.65, send in the powder stirrer, mix at normal temperatures; The B composition of hydrophobic fireproof heat-insulating material consist of emulsion 5~25, water 40~70, dicalcium powder 15~40, expansible black lead 0.5~2,3% BB1 water-resisting agent 0.02~2, film coalescence aid 0.01~5; Get the A composition according to described weight proportion and in powder stirrer, stir, get after the B component mixes, be sprayed at the expanded polystyrene particle surface; (CaO+MgO) content of described grey calcium powder is not less than 60%, described glass fibre is that the weak point of 8~12mm is cut alkali resistant glass fibre, described film coalescence aid is an alcohol ester-12, and the particle diameter of described expanded polystyrene particle is that 2~6mm, tap density are 8.0~21.0Kg/m 3, described emulsion can be a benzene emulsion, also can be organosilicon crylic acid latex or pure-acrylic emulsion.
Penetrant crystalline is by ordinary Portland cement, the mixture that meticulous quartz sand and active chemistry are made into, active chemistry is carrier with water, along with water permeates the concrete structure hole, be seeped into by stream in the hole seam of concrete inside configuration, the Ca (OH) 2 and the Calucium Silicate powder of separating out in catalysis Calucium Silicate powder and the hydrated reaction of cement process reflect alternately, formed water-fast complicated and confused shape fiber crystallisate, crystallisate is in the inner water-swelling of concrete structure, by dredging to close, make the concrete structure top layer form one gradually to close impervious zone, thereby effectively improved the impervious outlet capacity of concrete structure to depth.Because active chemistry can also activate by water for many years, continue to play katalysis, even so the local impaired seepage of concrete structure (crack is less than 0.4mm) under crystallization, can repair healing voluntarily, and have repeatedly impervious ability.
It is that alkali resistance is good that weak point is cut the alkali resistant glass fibre characteristics, has very high corrosion resistance nature in cement and other alkaline mediums, can be used for refinforced cement, gypsum and other inorganic materials.
Expansible black lead has following superperformance: extremely strong anti-low high temperature, anticorrosive, radioprotective characteristic, extremely strong anti-thermal shock characteristic, when being subjected to more than 200 degrees centigrade high temperature, because the decomposition of occlusion compound in layer lattice, expansible black lead just begins to expand, and the graphite after the expansion becomes the very low vermiform of density by former flakey, and reaches maximum volume in the time of 1100 degrees centigrade, if make its any expansion, when final volume can reach initial 280 times; Extremely strong resistance to pressure, snappiness, plasticity-and self lubricity; Extremely strong thermal conductivity and specific conductivity; Extremely strong anti-aging, anti-twist characteristic; Can resist the molten of various metals and reach infiltration; Nontoxic, do not contain any carcinogens, environment is safe from harm; Corrosion-resistant, impermeable, have not embrittlement of low temperature, not aging, not softening, indeformable, the Undec excellent properties of high temperature.
