Description
Technical field
The present invention relates to a kind of flame-retardant polystyrene warming plate and preparation method thereof, belong to wall thermal insulating plate technique neck
Domain.
Background technology
Expandable polystyrene warming plate is obtained by polystyrene with physical foaming agent and mixing, because its relative density only has
1.05, good heat insulating is most widely used building thermal insulation material.But common styrofoam will after temperature is more than 200 DEG C
Heat shrinkable simultaneously resolves into small molecule hydrocarbon, meets naked light and burns rapidly, and discharges big calorimetric, many building fires
All because insulation material causes.
In order to prepare safe building thermal insulation material, early in the eighties in last century, researchers just develop halogen flame retardant type
Styrofoam, but, halogen containing flame-retardant burning produces a large amount of noxious materials, seriously jeopardizes the life security of personnel, in the world
The use of strict limitation halogen containing flame-retardant.In order to prepare nontoxic flame retardant type styrofoam, researchers have carried out substantial amounts of nothing
The research work of halogen fire retardant, but, these fire retardants can cause the foam performance of styrofoam seriously to reduce so that material is being protected
There is larger defect on warm nature energy and mechanical property.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of flame-retardant polystyrene warming plate and its preparation side
Method, the flame-retardant polystyrene warming plate is to carry out strong acid oxidation processes to graphite, and modified graphite is obtained as fire retardant, is passed through
Prefoam processes expandable polystyrene bead, carries out secondary frothing forming, that is, the insulation of flame retardant type expandable polystyrene is obtained
Plate, the burning of effective prevention benzene plate.
