Abstract
The invention discloses an anti-static modification foaming cement and polyurethane foam composite insulation board. The composite insulation board is prepared from, by weight, 3-4 parts of waste cotton hemp fiber, 1-1.2 parts of chlorcosane, 0.3-0.34 part of fatty alcohol-polyoxyethylene ether, 45-50 parts of ultrafine Portland cement, 3.5-4 parts of hydrogen peroxide with the concentration being 30 wt%, 3-3.5 parts of gypsum powder, 2-3 parts of stearic acid, 2.5-3 parts of aluminum sulfate, 1.6-1.8 parts of organic silicon, 2-3 parts of a bisphenol A type epoxy resin emulsion, 2-3 parts of oxidized graphene, 0.8-1 part of polyvinyl alcohol, 0.7-0.8 part of 3-triethoxysilylpropylamine, a proper amount of deionized water, 75-80 parts of polyoxypropylene polyol, 23-25 parts of isocyanate, 2.2-2.4 parts of N,N,N,N',N'-pentamethyldiethylenetriamine, 10-12 parts of n-pentane, 1.5-2 parts of dimethicone and 8-10 parts of ammonium polyphosphate. The obtained composite insulation board resists static electricity and fire and achieves heat insulation.
Description
Technical field
The present invention relates to building materials technology field, more particularly, to a kind of antistatic modified foam cement and polyurethane foam are combined
Warming plate.
Background technology
Building Energy Conservation Policy and the enforcement of Building Fire Protection specification, have promoted the fast development of wall heat insulation material.Polyurethane
The organic insulation materials such as rigid foam plate, polystyrol plastic foam plate, phenolic foam plate, because of its insulation
Excellent performance has obtained relatively broad application in building heat preservation engineering.The fatal weakness of polyurethane foam is exactly flammability
Can, easily it is ignited, and combustion process release harmful gass.Even if with the addition of fire retardant also cannot fundamentally change this genus
Property, the highest burning rank of polyurethane foam board for building also can only accomplish b1 level.Cement insulation board, expanded perlite
The inorganic heat insulation materials such as warming plate, inorganic material parcel polyphenylene granule heat-insulating plate, can reach a level of classification system for fire performance not
Combustible material standard requires, and has also obtained more universal application in building field, but has because its thermal and insulating performance is less than
Machine insulation material, heat conductivity is 1.5-2 times of organic insulation material, and density is big, from great, with China's building energy conservation requirement
Step up, tend not to meet Current Building ' energy saving igniter requirement.Research and development are adapted to Current Building ' energy-saving design mark
The building thermal insulation material of alignment request and fire safety rules has become current study hotspot.
In " preparation of foam cement/injection composite insulation boards and performance study " literary composition, using cement insulation board as
One side template, injection foaming polyurethane material organic insulation material in a mold, heated, extrusion forming, formed after the demoulding and send out
Soaked mud/injection composite insulation boards, cement insulation board is located at the outside of foam cement/injection composite insulation boards, flammability
A1 level can be reached, when meeting fiery heat, heat is concentrated mainly on this, does not have too many heat and enters into polyurethane insulation coating, energy
Enough play fireproof effect.The composite insulation boards made have good fire protecting performance, and thickness is little, composite plate global density
Low, reduce the energy consumption in production process, environmental protection and energy saving；But because foam cement layer is located at the outside of warming plate, light weight is many
The feature in hole makes it have higher water absorption, and moisture content is higher, and heat insulating ability is poorer, and intensity is also lower, which limits compound
The application of warming plate, needs this is modified.
