Abstract
The invention relates to a modified polystyrene board. Pressure of superheated water vapor in a molding machine is regulated when a molding polystyrene foam board is manufactured, so that mutual spherical contact points of particle walls among polystyrene particles are in point type adhesion or contact points of the particle walls are extruded into a plane and a curved surface which are bonded; non-particle walls are severely extruded and deformed to form continuous and complete adhesion among the particle walls, so that the polystyrene particles are mutually self-adhered to form a thermal-insulation board in a mode of thermally melting surface layers of the polystyrene particles through superheated water vapor; a great number of non-adhesion parts are arranged outside the adhesion points or adhesion surfaces of the polystyrene particles, so that a great number of cavities are formed, and therefore, fireproof materials can be simply and conveniently injected into the cavities to form fireproof layers, and fire prevention is realized. The polystyrene particles are prevented from being adhered integrally by adding a great number of materials such as the adhesive, so that the cost is greatly reduced, and the effect is improved by several tens of times.
Description
Technical field
The present invention relates to a kind of insulation material of building field, especially a kind of modified polyphenyl plate and preparation method thereof.
Background technology
With national energy-saving standard continuous improvement and fire protection requirement it is more strict, insulation material is proposed it is higher will
Ask, the organic insulation material molded polystyrene foams plate that is widely used at present, extruded polystyrene foam board, hard bubble poly- ammonia
Ester, phenolic board almost enumerate whole B levels insulation materials, and above-mentioned organic insulation material heat insulation effect is very well and extremely convenient of constructing
Fast, but do not reach A levels fire prevention.In order to play the excellent heat-insulating property of organic insulation material, its fire protecting performance, mesh are lifted again
It is front generally polystyrene foam particles be added to fire prevention slurry agitation coat to form heat preservation slurry, above-mentioned heat preservation slurry is smeared and built
Smear thick and necessarily fallen for per layer on walling body, reaching existing thermal requirements need to smear 10 layers or so, the huge generalization of cost of labor
Extreme difference；Above-mentioned heat preservation slurry is poured in mould makes sheet material, it is also desirable to clear mould, formwork, brush releasing agent, cast, shaping, consolidate
The techniques such as change, the demoulding, maintenance, cutting, efficiency is very low, the very high extremely difficult popularization of cost.How organic insulation material is played excellent
Different heat insulation effect, gives its A level fire protecting performance again, at the same it is convenient for production it is quick, with low cost, it is easy popularization and without the later stage application
In face of vast insulation material researcher, this is also related to national heat preservation energy-saving political affairs to the pendulum of the high-quality insulation material of potential safety hazard
Can plan smoothly realize the major issue with people life property safety.
Chinese patent CN104072939A discloses a kind of construction material, and in particular to a kind of modified polyphenyl plate and its preparation
Method.Comprise the steps：1) foaming agent and curing agent are well mixed with the pre- granules of polystyrene sent out and component A, are formed
Component B, wherein component A are the mixture of Foamex, fire retardant, surfactant and inorganic filler；2) component B is uniformly poured
Note on the panel of laminating conveyor, after foaming, solidification, shaping product is obtained final product.The preparation of the modified polyphenyl plate that the document is provided
Method, is capable of achieving continuous prodution, and the production efficiency for solving original technique presence is relatively low, and the quality of product is unstable, qualified
The problems such as rate is relatively low.The product that the more original technique of product obtained by the serialization preparation method of modified polyphenyl plate is obtained is in mechanics
Have in intensity, heat-insulating property and security and largely lifted.
A kind of polystyrene/melamine modified urea is also disclosed that in another Chinese patent CN105111677A documents
Urea formaldehyde syntactic foam and preparation method thereof.The addition of larger fire retardant and relatively low flame retarding efficiency always limit poly-
The key factor of styrene materials development.Polystyrene of the present invention/cyanurotriamide modified urea resin syntactic foam, by institute
Cyanurotriamide modified urea resin, inorganic filler, fire retardant and the fire retarding synergist composition cyanurotriamide modified urea resin stated
Mixed fillers, the cyanurotriamide modified urea resin mixed fillers are 100 with the mass ratio of the granules of polystyrene sent out in advance：
20-70, cyanurotriamide modified urea resin mixed fillers are evenly coated at the pre- granules of polystyrene surface for sending out well.When flame connects
During tactile syntactic foam, the cyanurotriamide modified urea resin mixed fillers for being wrapped in outer layer carbonize to form protective layer, isolation
Flame, reaches the fire-retardant purpose of syntactic foam.
It is therefore seen that, modified polyphenyl plate is the product quite favored in building materials fire protection field.
However, how to make modified polyphenyl plate that both there is organic excellent heat-insulating property, A level fire protecting performances are reached again, and
Finished product can simply and efficiently be produced so as to the lifting that tens times of efficiency, it is especially a kind of for manufacturer in the industry for building materials field setting
The new industrial standard that can be referred to, still having the road of many innovations will walk.
The content of the invention
The technical problem to be solved is to provide a kind of modified polyphenyl plate and preparation method thereof, the modified polyphenyl plate
It is that a kind of interior shape has cavity and by the fire prevention molded polystyrene foams plate of fire prevention filled therewith, can by preparation method
Obtain
For this purpose, the technical scheme that the present invention solves the problem is：A kind of modified polyphenyl plate, including following components：Molding polyphenyl
Vinyl foam plate, fire prevention slurry；Wherein, described molded polystyrene foams plate, the granular polystyrene in its plate body is Jing particles
Contact with each other bonding between wall or particle wall contact point position be extruded to be formed one section of plane, curved surface be bonded together, it is adjacent
Shape of the particle wall in discontinuous bonding, and position has non-stick outside bounding point or adhesive surface between the granular polystyrene in plate body
The position of conjunction, and form cavity；The fire prevention slurry includes water, Lauxite, inorganic filler, curing agent, the fire prevention slurry
In being filled into the cavity formed between the molded polystyrene foams plate granular polystyrene.
Preferably, the preferred unit weight of the molded polystyrene foams plate is 6-20kg/m.
Preferably, the preferred solid content of the Lauxite is 40-60%, and viscosity can be phenolic aldehyde in 200-1500mpas
