Description
Technical field
What PVC foamed fireproofing A step of the present invention and preparation method thereof related to is prescription and the preparation technology's flow process that a kind of fire-protection rating reaches the PVC foaming plate of A level.
Technical background
In recent years, because fire takes place frequently, brought tremendous loss to the people's lives and property.The organic fire prevention plate generally can only reach the B1 grade standard; Can not reach the A grade standard of policies and regulations mandatory requirement, the builder has selected conventional inorganic fire plates such as rock wool again, but the inorganic fire plate has its unsurmountable shortcoming; As than great, raw material resources deficiency etc.These phenomenons have highlighted the present situation of building materials market shortage A level organic fire prevention plate.PVC itself has certain flame retardant resistance, uses as PLASTIC LAMINATED to have inborn advantage, and bigger but routine is extruded the PVC PLASTIC LAMINATED proportion of production, fire resistance does not reach national A level fire-protection standard.
Summary of the invention
The present invention seeks to provides a kind of PVC foamed fireproofing A step and preparation method thereof to above-mentioned weak point, adopts preparation technology's flow process of the present invention, and the foaming plate of producing can reach A level fire-protection rating.PVC foaming plate is because PVC itself just has certain flame retardant resistance, has the fire line that matches in excellence or beauty with inorganic fire-retarded plate through the plate that foams of the PVC after prescription and the process modification, and has light weight, advantage that hardness is high.Through check, use the PVC foaming plate of this prescription and explained hereafter to reach national A level fire-protection standard

Said softening agent can be selected phthalate, epoxies, polyester or trimellitic acid ester plasticizer for use.Said phthalate can be selected DOP (DOP) for use, and said epoxy plasticiser is selected epoxy soybean oil or octyl epoxy stearate for use; Said polyester softening agent can be selected polypropylene adipate(PPA) or hexanodioic acid Ucar 35 polyester for use; Said trimellitic acid ester plasticizer can be selected trioctyl trimellitate for use.
Said silicon-dioxide is hollow bead silicon-dioxide.
PVC foamed fireproofing A step is the preparation method may further comprise the steps:
1, choosing polyvinyl chloride resin (PVC RESINS), silicon-dioxide, white lake, thermo-stabilizer, whipping agent, softening agent by proportioning mediates in the high speed kneader; 20 ~ 40 minutes kneading time, the raw material that obtains mixing, wherein the parts by weight of raw materials proportioning is: polyvinyl chloride resin (PVC RESINS) 100 weight parts; Silica 1 50-200 weight part; White lake 20-50 weight part, thermo-stabilizer 5-10 weight part, whipping agent 4-20 weight part, softening agent 10-20 weight part.
2, the raw material that mixes is extruded through forcing machine, forcing machine heating raw temperature of fusion is 120 ℃～170 ℃, and extrusion temperature is 160 ℃, and cuts, and needing to obtain the pre-frothing PVC plate of size.
3, pre-frothing PVC plate is put into mould and seal, heating and pressurizing foams on vulcanizing press, 160 °～180 ° of Heating temperatures; Pressure is 15MPa; Keep this pressure and temperature 20～30 minutes, and be cooled to 160 ° of pressure releases, needing to obtain the foaming PVC plate of multiplying power; Cut deburring, make finished product.
In the described step 1 with all raw materials once or gradation add in the kneader, mediated 20 ~ 40 minutes.
The forcing machine that uses in the described step 2 can be twin screw extruder or single screw extrusion machine.
In the described step 3 mold heated to 160 ° is continued 20～25 minutes, make the raw material plasticizing forming, continue to be warming up to 180 ° whipping agent is decomposed, be cooled to 160 ° of pressure releases and obtain expansion ratio.
Described expansion ratio is 10～40 times.
PVC foamed fireproofing A step is because PVC itself just has certain flame retardant resistance, has the fire line that matches in excellence or beauty with inorganic fire-retarded plate through the plate that foams of the PVC after prescription and the process modification, and has light weight, advantage that hardness is high.Can be widely used in multiple fields such as wall thermal insulating, roof heat insulation, ground insulating.This technological operation is easy, has overcome the bigger shortcoming of foaming PVC plate proportion that traditional extrusion-type is produced.Through check, use the PVC foamed fireproofing A step of this explained hereafter to reach national A level fire-protection standard.
