Description
Technical field
The present invention relates to a kind of preparation of fibre reinforced composites warming plate, belong to heat preserving and insulating material technical field.
Background technology
China's building energy consumption is very huge, and its major reason is that the heat transfer coefficient of building maintenance structure is larger, and heat insulation effect is poor, develops so a kind of novel wall lagging material and just seems very necessary.The current two class wall heat insulation materials that mainly contain: thermal insulation mortar and heat preservation plate material.Thermal insulation mortar is taking various light materials as aggregate, taking cement as gelating material, admix some property-modifying additives, when use, add water in proportion and be uniformly mixed the slurry forming, it can spray or the mode of manually smearing is coated in the outside surface of building maintenance structure by machinery, and conventional thermal insulation mortar has: adhesive polystyrene granule heat-insulating mortar, complex silicate aluminium thermal insulation mortar etc.; And heat preservation plate material is exactly that general thermal insulation mortar is carried out to blanks and moulding and conserving, manufactured Board uses, and the crab-bolt by some amount and assembly glue make it be fixed on the heat-insulation system that outside surface that Jian builds Wei Hu Jie Ju forms for it.Wall heat insulation material is of a great variety, but all has certain defect and deficiency, and development of new lagging material is extremely urgent.
Summary of the invention
The object of the invention is the deficiency existing for existing wall heat insulation material, disclose a kind of high-strength light, waterproof fireproofing, heat insulating, weather-proof good endurance, and there is environmental protection, nontoxic, the preparation of fibre reinforced composites warming plate easily of constructing.
The object of the invention is to be achieved through the following technical solutions, a kind of preparation of fibre reinforced composites warming plate, it is characterized in that, in the heat preservation slurry of unit cubic meter, the mass ratio of granular polystyrene, cement, water, flyash, redispersable latex powder, tubular fibre, Vltra tears, hydrophobic powder is 1.000: 20.526: 12.158: 2.947: 0.263: 0.089: 0.221: 0.263.
Preparation process is as follows:
1) cement of the flyash of mass ratio 2.947, mass ratio 20.526 is poured in stirrer, added mass ratio 12.158 water and stir 1 minute, it is fully mixed;
2) above-mentioned 1) compound in add again the tubular fibre of redispersable latex powder, the mass ratio 0.089 of mass ratio 0.263, the hydrophobic powder of mass ratio 0.263, the Vltra tears of mass ratio 0.221 to stir 30 seconds, wherein Vltra tears will first stir and open with warm water;
3) above-mentioned 2) compound in to pour gently mass ratio into be 1.000 granular polystyrene, fully stir 5 minutes, make granular polystyrene surface uniform wrap up in slurry;
4) by above-mentioned 3) mixed slurry that stirs pours compacting in mould into and strikes off;
5) form removal after 6 hours, carrying every other day, normal curing.
The present invention prepares the warming plate test specimen under best proportioning, measures one by one respectively dry density, thermal conductivity, ultimate compression strength, tensile strength, water-intake rate, drying shrinkage value, the coefficient of softening of test specimen, and with the comparison of specification index, it the results are shown in Table 1.
The performance index of table 1 fibre reinforced composites warming plate
The property indices of the warming plate test specimen of preparing by above proportioning as can be seen from Table 1, all meets the requirement of " composite material thermal insulation plate external thermal insulation system utilisation technology code " (JG/T 045-2011 of Soviet Union).
The invention has the beneficial effects as follows: (1) adopts fibre reinforced composites warming plate prepared by this quality mixture ratio can reach the goodish impact of performance; (2) preparation is simple for this fibre reinforced composites warming plate, easy to operate.
