Abstract
Polymer concrete, with ordinary Portland cement, flyash is as matrix, and expansion polystyrene stirs through mixing as light-weight aggregate, vibratory compaction, high temperature steams presses, and dries and vacuumize to handle to make.Because the present invention has made full use of the low melting point thermoplasticity characteristics of expanded polystyrene, makes goods of the present invention not only have light weight, good heat insulating also has high-intensity wood property, can be used to make the supporting member of buildings, and is of many uses.
Description
The polystyrene concrete relates to the polymer concrete manufacture technology of composite material.
Existing polymer concrete mainly contains 1) adopt that admixture is applicable to the polymer cement concrete (PPC) that the aqueous of cement or dispersed polymkeric substance and auxiliary agent are made in cement, 2) polymer impregnated concrete (PIC) that adopts molded hardened cement concrete base material to obtain after heating or radiation exposure make it polymerization, 3) directly adopt the concrete of synthetic resins as agglutinate with the polymer monomer dipping.Owing to admixture polymkeric substance in the cement, influenced the hydration of cement, cement products regular meeting sticks on the template, causes goods to damage during form removal, has influenced the quality of cement products; Adopt the polymer monomer steeping fluid to come the impregnated concrete goods, not only the polymer monomer dipping costs an arm and a leg but also is restricted to the size of concrete product, applies thereby influenced.
The report that adopts expansion polystyrene to make the thermal insulation concrete goods is arranged abroad, but expansion polystyrene in goods as just the surrogate of former light-weight aggregate, in order to reduce the weight of thermal insulation concrete goods, so the intensity of this thermal insulation concrete goods is not high, can not be used for the supporting member of buildings.
The objective of the invention is to, utilize the thermoplastic characteristics of expanded polystyrene low melting point, adopt silicate cement, flyash to make porous, lightweight, insulation, high-strength as matrix, cost is low, can make the polystyrene concrete of supporting member.
The present invention adopts the ordinary Portland cement adding coal ash as matrix, and expansion polystyrene is poured into mould as light-weight aggregate after stirrer mixes stirring, vibratory compaction, and high temperature steams presses, and makes the abundant aquation of matrix, and intensity improves.Because polystyrene and moist material bad adhesion; so; the matrix that steams after pressing can't bond together well with the hot expansion polystyrene that melts; therefore; steam the pressure back at high temperature processing is dried and vacuumized to goods again; make the free water content that contains in the goods fully evaporate; has certain trickling degree under the high temperature after the granules of polystyrene fusion; penetrate in the matrix space with the matrix tight bond together; thereby make porous, light weight; insulation, high-strength polystyrene concrete.
The invention has the advantages that:
1, because concrete product intensity of the present invention greater than aerated concrete products, is made reinforcement wallboard, floor and building block so it can substitute gas concrete.
2, the present invention only needs just to adjust slightly and can go into operation on available coagulation soil production of articles line, so less investment, helps applying.
3, the expansion polystyrene that adopts of the present invention can give that the depleted polystyrene packing material replaces turning waste into wealth to reach in expanded polystyrene particle and the daily life with industrial, reduces environmental pollution, tangible economy is arranged, social benefit.
4, the present invention makes the present invention not only have the performance of lightweight, insulation owing to made full use of the characteristic of expanded polystyrene, also has high-intensity wood property, sees Table one.Because normal concrete tensile strength is low, tension and pressure-resisting ratio are about 1/10, and concrete tension of polystyrene and pressure-resisting ratio are about 1/5.3, are 2 times of normal concrete approximately.Thereby can make the supporting member of buildings, more of many uses than general light weight concrete.

Accompanying drawing is the process flow sheet of the embodiment of the invention, and existing the invention will be further described in conjunction with the accompanying drawings.
Fig. 1, polystyrene concrete making technology schema.
Silicate cement, flyash, expansion polystyrene and water are put into stirrer for mixing and are stirred, and wherein cement is 1: 1 than flyash, and the addition content of expansion polystyrene is 50～60% of cement and a flyash cumulative volume.Mix to even back compound is poured in the mould, vibratory compaction on shaking table, the time of vibratory compaction come-up do not occur with the light-weight aggregate in the compound and is advisable.After the vibratory compaction, floating product surface, the maintenance one day in curing room of band mould.
Maintenance finishes, remove template after, goods are placed on give earlier under 50 ℃ the temperature and supported 4～6 hours, under 180 ℃ of high temperature, steam then and pressed 9 hours.Because the bonding of polystyrene and moist material is relatively poor, dry so after steaming pressure, goods are placed under 105 ℃ of temperature so that the free water content that contains in the goods evaporated and make expansion polystyrene at high temperature heat melt.At last at 180 ℃ of high temperature, vacuumized 0.5～3 hour under vacuum tightness 600～700 mmhg, the polystyrene that has certain trickling degree behind the hot melt is penetrated in the hole of matrix around it to be gone closely to bond together with matrix, further improve the intensity of goods, thereby make the light high strength concrete that not only is incubated but also can load-bearing.
