Abstract
The invention relates to an expandable polystyrene resin board which is characterized by comprising the following components by weight percent: 90% to 95% of styrene, 2% to 6% of foaming agent, 0.5% to 1.5% of fire retardant and 1% to 3% of water. In the expandable polystyrene resin board, the prepared board has good fire retardant property by reducing the content of the foaming agent and increasing the content of the fire retardant in raw material formulation of the expandable polystyrene resin board. In addition, the board meets the requirement of China's fire retardant standards and is updated to B1 level from B2 level.
Description
Technical field
The present invention relates to a kind of expandable polystyrene resin sheet material, especially relate to a kind of prescription of expandable polystyrene resin plate, belong to chemical technology field.
Background technology
Eps (EPS) is owing to have the heat insulation property of excellent durable, unique buffering shock resistance, resistance to deterioration and water-repellancy; Thereby obtained in a lot of fields using widely; Especially the application in the heat insulation and sound-proof material in buildings is very extensive; And the sheet material that utilizes eps preparation is to be raw material with the expandable polystyrene particle that contains the volatile liquid whipping agent; After the preheating foaming, the foam plastics slab of fine unicellular structure is processed, is had in extrusion forming in mould.Content corresponding fire retardant is lower and the expandable polystyrene resin sheet material of selling on the market at present is because the content of whipping agent is high, so it is when being used for buildings as lagging material, and its flame retardant effect is difficult to satisfy the flame-retardant standard requirement of China.
Summary of the invention
For solving the deficiency of prior art, the object of the present invention is to provide a kind of expandable polystyrene resin sheet material of good flame retardation effect.
For achieving the above object, the present invention realizes through following technical scheme:
A kind of expandable polystyrene resin sheet material is characterized in that, comprises that the quality percentage composition of following component and each component is respectively:
Vinylbenzene: 90%-95%;
Whipping agent: 2%-6%;
Fire retardant: 0.5%-1.5%;
Water: 1%-3%.
Described whipping agent is a pentane, its quality percentage composition preferred 5%.
Described fire retardant is any one in tricresyl phosphate (2-chloropropyl) ester, hexabromocyclododecane, TDE, the zinc borate, its content preferred 1%.
The invention has the beneficial effects as follows: the present invention is through reducing the content of whipping agent in the composition of raw materials of expandable polystyrene resin sheet material; And the content of increase fire retardant; Realize producing the sheet material that forms and have the good flame performance; Satisfy the requirement of China's flame-retardant standard, be elevated to the B1 level from original B2 level.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
In this embodiment, described whipping agent is a pentane, and described fire retardant is a zinc borate.
Embodiment 1:
Expandable polystyrene resin sheet material comprises that the quality percentage composition of following component and each component is respectively: vinylbenzene 90%; Whipping agent: 6%; Fire retardant: 1.5%; Water: 2.5%.
Embodiment 2:
Expandable polystyrene resin sheet material comprises that the quality percentage composition of following component and each component is respectively: vinylbenzene 93%; Whipping agent: 5%; Fire retardant: 1%; Water: 1%.
Embodiment 3:
Expandable polystyrene resin sheet material comprises that the quality percentage composition of following component and each component is respectively: vinylbenzene 95%; Whipping agent: 3%; Fire retardant: .0.5%; Water: 1.5%.
Wherein, be most preferred embodiment with embodiment 2.
The concrete steps of the quality percentage composition production expandable polystyrene resin sheet material of the described component of embodiment 1-3 and each component are following: vinylbenzene carries out polyreaction and generates the polystyrene resin particle; And then add whipping agent and carry out the aeration foamable reaction, and then promptly obtain expandable polystyrene resin sheet material through slaking, compression molding, drying, cutting.
Utilize the described quality percentage composition production expandable polystyrene resin sheet material of embodiment 1-3 following: density (kg/m3): 15-30 through testing its performance perameter with the described component of embodiment 1-3 and each component; Thermal conductivity (W/mh): 0.041; Tensile strength (kg/m2): 2.5-3.5; The dimensional stability use temperature (℃) :+70.And its anti-flame retardant properties has reached the B1 level, has satisfied the flame retardant properties requirement of China to external-wall heat-insulation material.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
