Description
Technical field
The invention belongs to the technologies of preparing of fire retardant, in particular to the system without resin, the nano flame retardant masterbatch of binder free
Preparation Method and application.
Technical background
Nano level flame retardant powder is due to nano effect, compared with conventional flame retardant, has excellent performance.
However, nanometer powder surface hydrophilic oleophobic, easy reunion is difficult to directly apply, it is necessary to by surface treatment.In table
In terms of surface treatment, used at present is that wet mixing is legal, i.e., first mixes nano flame retardant powder, surface treating agent and a large amount of solvent
Stirring is closed, fire-retardant slurries are made.Then fire-retardant slurries are filtered, obtains fire-retardant powder filter cake.Filter cake is after pulverizer crushes
Obtain smashed fire retardant wet cake.Wet cake crushes break up again, after can finally obtaining surface treatment after drying
Nano flame retardant powder.The legal complex process of wet mixing, production cycle length, high production cost.
And nano-powder is easy to produce dust, to worker's health and workshop condition in production and process
All have a great impact.Current solution is that masterbatch is made in nano material.But the method has certain defect, such as carries
Body resin must be consistent with final resin, and the lubricating system in conventional masterbatch must match with final resin, otherwise easily
Cause the sharp fall of fire proofing physical and chemical performance.Further, since material used in the plastic product client of downstream is a variety of
Multiplicity, therefore flame-retardant master batch manufacturer will also convert basis material when doing masterbatch to solve the problems, such as compatibility, very
It is cumbersome.
In terms of granulation, it is currently used have squeeze out tie rod water cooling, fervent water cooling, earnestly air-cooled or screw extruder (it is single/
It is double) carry out the technologies such as extrusion granulator.These granulation techniques needs are handled raw material under conditions of vacuum compression or heating,
Production technology is complicated, and the production cycle is longer, high production cost.And the peculiar smell that high temperature generates plastics is big, and electricity consumption is big, worker
Large labor intensity.The masterbatch especially produced since through extrusion process, brittleness is big, dust is more, and dispersion effect is general,
The demand for not only being well positioned to meet production, using, but also many troubles are brought to daily production and application.
In order to solve these problems, the present invention does not add resin, binder and lubricant in pelletization, therefore fills
Amount is high, versatility is good, effective component is high.And it can reduce cost.
The present invention carries out surface activation process to the fire-retardant powder of nanoscale using depolymerizing agent, can effectively avoid fire-retardant mother
After material is added in matrix resin, nanometer grade powder cannot uniformly be distributed to the problems in matrix resin because of hard aggregation.
Nano flame retardant powder is activated using continuous powdery surface modifying machine, can play and coat on one side, one
Frontier defense stops the effect of nanometer powder polymerization.The hard aggregation of nanoscale fire proofing can effectively be prevented.
The present invention uses dry-mixing cladding process, and depolymerizing agent is uniformly coated on nano flame retardant powder surface.It is closed with wet mixing
Cladding process is compared, and dry-mixing cladding process is low containing quantity of solvent in whole process due to using continuous powdery surface modifying machine, therefore
Powder is completed while not needing filtering, crush, is dry, crushing the multiple steps broken up again, but coat in modifying machine
Drying, break up depolymerization, one step of whole process can be completed.This greatly simplifies technical process, and reduce energy and disappear
Consumption, entire production process is without discharge, whole process closing, without dust pollution.The requirement of green, energy-saving and environmental protection can be reached.
Flame-retardant master batch is made in the fire-retardant powder of nanoscale, can be effectively solved " the frame generated during production application
Bridge " phenomenon.It is of special importance that can be effectively solved in fire-retardant powder use process since powder is flown upward, bring is to work
The problem of human body health and workshop condition all have a significant impact.And powder can be reduced to fly upward, to the wear problem of equipment.
It is pelletized using dry type roll-in granulator, with short production cycle, simple process, granulation product compression strength is big, produces
Amount is big, does not generate secondary environmental pollution.And with conventional extrusion tie rod water cooling, fervent water cooling, earnestly air-cooled or Screw Extrusion
Machine (mono-/bis -) granulation is compared, and is not needed to heat using dry type roll-in granulation mechanism grain, can be effectively reduced energy consumption.
