It is again stirring for uniformly after alkene fiber and additive, pre-hardening 1～2h；
(2) stand 10h after the completion of initial set, carry out the demoulding；
(3) natural curing 3～5 days after the demoulding, are shaped to blank；
(4) as needed blank is cut, obtain finished product.
The invention provides a kind of low stress cracking resistance warming plate, by cement, admixture, hydrogen peroxide, polypropylene fibre, water with
And additive composition, as material, addition admixture can carry out certain modification, reduction production cost etc. to cement；Add double
Oxygen water energy enough quickly promote cement foamed, make cement and expanded become foam cement, produce a large amount of sealed porositys inside it, have
Good heat-proof quality, density is little lightweight, has outstanding sound-proof refractory performance simultaneously, and its internal rate of closed hole is high simultaneously, water
Divide and cannot invade, have outstanding water-resistant anti-freezing effect；Also polypropylene fibre is included, itself light weight, intensity in the present invention
High, elasticity is good and has outstanding warmth retention property, mixes in the present invention, can make this while ensureing not increase own wt
Invention has outstanding anti-cracking function；Additive in the present invention equally can play certain modification, potentiation effect to the present invention
Really.
The present invention enables to the present invention in later strength not when making using the technique of initial set under low temperature stress
Become, do not degenerate, each composition performance of itself and activity in the present invention can be kept, and shrinkage factor is little, can be prevented effectively from this
Invention finished product ftractures, seeps water.
Preferably, the constituent of the present invention and mass fraction shared by each composition are respectively as follows:
Cement: 180 parts,
Admixture: 35 parts,
Hydrogen peroxide: 4 parts,
Polypropylene fibre: 1 part,
Water: 90 parts,
Additive: 4 parts.
The invention provides one group of optimal proportion, specific as follows: cement: 180 parts, admixture: 35 parts, hydrogen peroxide: 4 parts,
Polypropylene fibre: 1 part, water: 90 parts, additive: 4 parts；The finished product thermal insulation plate being obtained by above composition proportion has outstanding
Resistance to compression, anti-folding, tensile strength, the coefficient such as its water absorption, impermeability, weatherability, freeze-thawing resistant and ant wind load is all higher than phase
The like product of congruent composition.
Preferably, admixture is flyash.
In the present invention, admixture selects flyash, can greatly reduce the materials of cement, reduces manufacturing cost.
Preferably, additive is water reducer.
Water reducer in the present invention can substantially reduce unit consumption of water, improves mixture after each composition mixing in the present invention
Mobility, reduce cement consumption, reduce manufacturing cost.
Preferably, natural curing in step (3) method particularly includes: wrapped using plastic sheeting in 2h after the demoulding
Wrap up in, under the conditions of being positioned over natural temperature, and be completely covered with wet soil, continue 3～5 days.
The present invention compared with prior art, using formula and the method for novelty, is ensureing that warming plate has superior mechanical
While performance, also make it have outstanding insulation, waterproof and dampproof performance, greatly improve product quality, and also can
Be prevented effectively from the cracking of product, infiltration so as to after a procedure the phase still ensure that every outstanding performance indications, cost simultaneously
Moderate, preparation method is simple.
