It is that China economizes on resources the fundamental state policy promoted economic development.China brings up to the energy conservation standard of residential housing from 65%
75%, the energy conservation standard of public building also brings up to 65% from 50%.But current traditional wall and insulation construction system can not
Adapt to the demand for development of energy-conservation new standard and new situations.
Subject matter existing for the conventional outer wall heat-insulation system that China is currently built is：
1st, heat insulation system：Poor safety performance, grade are low, disaster hidden-trouble (fire proofing and fire-blocking belt) and big face be present
Product such as comes off at the safety problem；Service life is short, maintenance cost is high (deformation unreasonable, easy to aging of system construction, crack and water leakage etc.)；
2nd, insulation material：(organic material) of good heat insulation is not prevented fires, easy to aging；Fireproof (inorganic material) unit weight is big, thoroughly
Gas, permeable, poor thermal insulation property, short life；
3rd, design application：It is unable to load-bearing, durability, ant wind load and poor seismic behavior.
Therefore research and development should be high-efficiency insulated, and fire safety (not falling off), moreover it is possible to structure load-bearing；It is easy for construction, make
Valency is relatively low；The longer building heat preservation system of service life and new structure insulating wall material, it has also become China's energy saving building is sent out
The great difficult problem to be solved is badly in need of in exhibition.

The beneficial effects of the invention are as follows：In formwork produces raw material, by adding high molecular polymer waterproofing agent, with height
The polymer water slurry body that grade cement collectively constitutes, it is multiple by being formed after the mixing with grading granular polystyrene, bonding and hardening
Insulation material is closed, the polymer cement skeleton of its spatial networks closed, changes the waterproof (water absorption rate and water-fast of formwork building block
Property) performance, its durability (water resistance and frost resistance) and fire resistance are greatly improved, has both met the heat-insulating property of wall and resistance to
Fiery characteristic (is not burnt and discharged without toxic smog yet), and can greatly prolong its service life (design service life 50 years with
On).
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, a kind of processing technology of modified cement polyphenyl formwork building block, comprises the following steps：
(1) required raw material components are weighed according to above-mentioned formula and be equipped with；
(2) using lightweight aggregate forced stirrer by with the raw material uniform mixing got ready；
(3) pressure forming machine is utilized by the raw material compression molding of uniform mixing；
(4) the raw material of compression molding is subjected to natural curing 28 days, cement polyphenyl formwork semi-finished product are made；
(5) cement polyphenyl formwork building block finished product is made through being bonded matched moulds in two pieces of semi-finished product cement polyphenyl formworks.
It is using the above-mentioned further beneficial effect of scheme：By skilled worker's technique of above-mentioned steps, modified formwork building block
Main technical performance index：In dry apparent density (330 ± 15%) kg/m3, compression strength (0.4~0.7) MPa, heat conduction system
In the case that number (0.07~0.09) (W/mK) is basically unchanged, other indexs are brought up to：Volume water absorption rate≤20%, softening system
Number >=0.8, frost resistance (25 freeze thawing time circulation) loss of strength≤5%, mass loss≤3%；Modified cement polyphenyl formwork lattice
The carrying fire endurance of formula concrete composite heat insulation wall reaches more than 3 hours, and wall does not lose bearing capacity, do not lost in itself
Go integrality and do not lose thermal insulation.
