Description
Technical field
The present invention relates to extruded polystyrene board field, and in particular to a kind of new modified extruded polystyrene board.
Background technology
With the continuous lifting of present scientific and technological level, people are enjoying the scientific and technological facilitation for bringing simultaneously, also to life product
The pursuit more and more higher of matter.
Polystyrene foam plastics is divided into dilatancy EPS and two kinds of continuity extrusion type XPS, compared with EPS sheet material, XPS
Plate is the hard foamed insulation material of the third generation, and it overcomes the numerous and diverse production technology of EPS sheet from technique, cannot be replaced with EPS sheet
The superior function in generation.It is to possess continuous uniform top layer through what extrusion process was produced by polystyrene resin and other additives
And the sheet material of closed pore formula honeycomb, extruded sheet has close hole-closing structure, and polystyrene molecular structure does not absorb water in itself, plate
The positive and negative of material is all without gap, therefore water absorption rate is extremely low, and moistureproof and anti-permeability is splendid.
But because traditional extruded polystyrene board thermal conductivity is strong, good heat insulating ability effect is not often reached in actual use
Really.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of new modified extruded polystyrene board so that reduce tradition and squeeze
Modeling styrofoam heat conductivility.
To realize object above, the present invention is achieved by the following technical programs：
A kind of new modified extruded polystyrene board, processing technology is as follows：
1) polystyrene mother material and white carbon are added and is extruded in extruder, and extruder is divided into 4 humidity provinces,
First 170-190 DEG C of humidity province, 200 DEG C of second temperature area, the 3rd 195 DEG C of humidity province, the 4th 165 DEG C of humidity province；
2) select foaming agent and it is pressurizeed, and the extruder head heating of the extruder that foaming agent pipeline is connected will be connected
Pump is heated；
3) to step 1) extrusion raw material extruder in implantation step 2) pressurized treatments foaming agent；
4) by step 3) treatment and extruded machine extruder head discharging sheet material carry out forming operation into forming machine；
5) by step 4) treatment sheet material carry out cutting grinding process.
Preferably, described step 1) before processing needs to carry out warm-up operation to extruder whole device machinery.
Preferably, described step 1) in heating temperature be 80 DEG C.
Preferably, described step 2) pressurization rear foaming agent spray frequency be 10HZ.
Preferably, described step 1) in extruder extruder head temperature be 160 DEG C.
Preferably, described step 4) forming machine first carries out the slow traction at extruder extruder head position, enters again after cooling
Row second traction is molded.
The invention provides a kind of new modified extruded polystyrene board, the temperature change of extruder multizone may be such that polyphenyl
Ethene masterbatch and white carbon are well mixed, white carbon link are added in sheet material uniform, it is ensured that added before suction extrusion hopper,
And be thoroughly mixed, white carbon is uniformly added in the middle of extruded polystyrene board after so ensuring to make finished product, reduces traditional extrusion molding
Styrofoam heat conductivility, heat insulation effect is obvious.Greatly reduce traditional extruded polystyrene board heat conductivility, can in actual applications by
Further genralrlization.
