Description
Technical field
The invention discloses a kind of preparation method of high breaking strength type fireproof heated board, belongs to sheet material technology of preparing neck
Domain.
Background technology
The easy-to-understand plank exactly to building insulation that warming plate is said.Warming plate is using polystyrene resin as raw material
Plus other supplementary materials and poly- inclusion, by heating mixing injecting catalyst simultaneously, then extrusion molding extrusion molding and manufacture
Rigid foam plate, there is moistureproof, water resistance, reduction building envelope thickness can be made, made so as to increase interior
Use area.
Frequent species has：XPS warming plates：It is to contain using polystyrene resin as raw material plus other supplementary materials with poly-
Thing, by heating mixing injecting catalyst simultaneously, then extrusion molding extrusion molding and the rigid foam plate that manufactures.Its scientific name
For extrusion molding polystyrene polyfoam for heat insulation, XPS has perfect closed honeycomb structure, and it is extremely low that this structure allows XPS plate to have
Water imbibition, low thermal conductivity coefficient, ageing resistance.Easily make sheet material damage, cracking；Poor air permeability, it is almost airtight, if plate two
The temperature difference of side is larger, and humidity height is easy to condense；Because plate surface is smooth, man-hour requirement interface processing is being applied, and carry out plucking.
Hair side plate is within the rule；XPS plate bonds loosely with motar, easily comes off；Outer tiling comes off faster more serious.
Polyurethane thermal insulation board：Hard polyurethane board thermal conductivity factor is low, and thermal property is good.When hard polyaminoester unit weight be 35~
40kg/m3When, thermal conductivity factor is only 0.018~0.023W/（m·k）, EPS half is approximately equivalent to, is in all insulation materials
The minimum one kind of thermal conductivity factor.Hard polyurethane board has moistureproof, water resistance.The rate of closed hole of hard polyaminoester more than 90%,
Belong to hydrophobic material, thermal conductivity factor will not be increased because of the moisture absorption, metope will not also seep water.Hard polyaminoester is fire-retardant, high temperature resistant.It is poly-
Urethane is a kind of fire retardant self-extinguishing after fire retardant is added, and its softening point can reach more than 250 degrees Celsius, only compared with
Decomposition just occurs during high-temperature：In addition, polyurethane can form ash in burning in its foam surface, this layer of ash is helped under isolation
The foam in face.Fire spread can effectively be prevented.But warming plate class formula, proportioning are mixed and disorderly, unstable, cause sheet material physically stable
Property is poor, and heat insulation effect is bad；Spraying class application property not yet solves, it is difficult to ensures construction quality.
Existing most of warming plate can not all have high breaking strength and fire protecting performance simultaneously, give warming plate use range
Bring limitation.
Therefore invent a kind of high breaking strength type fireproof heated board has positive effect to sheet material preparing technical field.
