Abstract
The invention provides the preparation method of a kind of nanometer of stalk modified polypropene material, it is added to using nano modification stalk as fire-retardant filler in polyacrylic preparation.The present invention instead of poisonous and hazardous halogenated flame retardant using nano modification stalk, because nano modification stalk is to be dispersed in nano particle state in polypropylene matrix, it can generate oxide and vapor when heat is decomposed, vapor, which waters down, dilutes imflammable gas, and the generation of oxide helps to make flameout, serve the effect for suppressing burning, generate protective layer and be covered in polymer body surface, isolate burning things which may cause a fire disaster and oxygen, therefore composite is made to be provided with good fire resistance, the present invention is effectively utilized agricultural wastes straw simultaneously, it is made to turn waste into wealth, create new application value.
Description
Technical field
The invention belongs to the preparation method of technical field of composite materials, more particularly to a kind of nanometer of stalk modified polypropene.
Background technology
Polypropylene material has the advantages that light weight, inexpensive, good processing characteristics, good mechanical property, quilt due to it
It is widely used in the fields such as automotive material, electronic apparatus, construction material and packaging material.But polyacrylic oxygen index (OI) is only 18%,
Belong to combustible material, there is many potential safety hazards in use, once occurring fire, a large amount of molten drops can be produced, promote fire
Gesture spreads.So in some special dimensions, it is necessary to which polypropylene has preferable flame retardant effect.
Conventional fire retardant is halogenated flame retardant at present, due to its efficient flame retardant effect, is widely used in flame-retardant polypropylene
During alkene is material modified.But, the based flame retardant can discharge substantial amounts of poisonous and hazardous gas in burning, such as hydrogen halides,
The gases such as bioxin, cause secondary pollution, seriously endanger life security and Environmental security.
Stalk is widely present in China, and substantial amounts of stalk can be all produced every year, is a kind of in polymer-modified application stalk
The behave turned waste into wealth, on the one hand can give increasing peasant income, on the other hand can reduce the dirt that the burning of stalk is caused to environment
Dye.
The content of the invention
It is an object of the invention to provide a kind of nanometer stalk for not using halogenated flame retardant and having good fire resistance
The preparation method of modified polypropene.
The purpose of the present invention can be achieved through the following technical solutions：
The preparation method of the nanometer stalk modified polypropene of the present invention, it comprises the following steps：
(1) stalk is crushed to clean and adds mass fraction in 2-4% sodium hydroxide solution, 8- is soaked at 40-50 DEG C
Taken out after 16h and clean drying；
(2) configuration concentration is used as precursor solution for 0.5-1.0molL-1 AlO2- solution；
(3) stalk after drying is placed in vacuum impregnation in precursor solution；
(4) by the stalk after vacuum impregnation at 120-150 DEG C, the constant temperature 5-10h in hydrothermal reaction kettle is cooled to room
Temperature, takes out washing, and nano modification stalk is crushed to obtain in vacuum drying；
(5) 80-90 parts of polypropylene, 10-20 parts of lubricants are weighed, are added high mixed in high mixer；
(6) 50-60 parts of nano modification stalks are weighed, height in high mixer is added to and mixes, continuously add 2-3 parts of compatilizers, 1-3
Part antioxidant, height is mixed, takes out standby；
(7) step (6) resulting material is added in double screw extruder, in 140-200 DEG C of extruding pelletization.
In the preparation method of nanometer stalk modified polypropene described above, it is preferred that step (1) described stalk is corn
Stalk or wheat stalk.
In the preparation method of nanometer stalk modified polypropene described above, it is preferred that step (2) described AlO2 -Solution is
NaAlO2Or KAlO2Solution.
In the preparation method of nanometer stalk modified polypropene described above, it is preferred that at step (3) described vacuum impregnation
The reason time is 5-8h, vacuum 0.1MPa.
In the preparation method of nanometer stalk modified polypropene described above, it is preferred that the temperature of step (5) described high mixer
Degree is 75 DEG C -90 DEG C, rotating speed is 500-800r/min.
In the preparation method of nanometer stalk modified polypropene described above, it is preferred that step (5) described lubricant is selected from
One or more in zinc stearate, ethylene bis stearamide, erucyl amide, polypropylene wax, Tissuemat E, oleamide.
In the preparation method of nanometer stalk modified polypropene described above, it is preferred that step (6) described compatilizer is poly-
