Description
Technical field
The invention belongs to field of high polymer material modification, be mainly used in cosmetology device curling iron and require size
In stable height heat-resisting super-toughened nylon product.
Background technology
Curling iron in cosmetology equipment is welcome by more people seeking beauty in daily life, but in curling iron
There is many influence factors because of mould structure, raw material selection etc. in the fabrication process in comb tooth material, below we only with regard to former material
The selection of material is had a talk.
It is said that in general, toughness and the conflicting defect of thermostability can be there is in super-toughened nylon: after adding grafted elastomeric
PA66 becomes ultra-toughness material, because the thermostability of grafted elastomeric own is relatively low, result in the heat-resisting of ultra-toughness material and is greatly affected,
The super-toughened nylon ST801 produced including E.I.Du Pont Company there is also this use defect.For overcoming this use defect, introduce the 3rd
Component material becomes inevitable choice.Add glass or filler and can be effectively improved the heat-resisting of super-toughened nylon, but this two classes thing
Matter but toughness to material causes irreparable damage.Thus manufacture nylon alloy material and become preferred option, commonly
In engineering plastics, only the temperature of use continuously of polyphenylene oxide and Merlon is with nylon66 fiber (being called for short PA66) quite, because of common double
Phenol A type PC (aliphatic types PC heat distortion temperature is the highest, expensive, abandons) heat distortion temperature and nylon66 fiber heat distortion temperature
Differ greatly, it is not recommended that use.In PA66, add a small amount of PPO (Chinese name: polyphenylene oxide) former powder can improve the heat-resisting temperature of PA66
Degree,
Summary of the invention
The technical problem to be solved in the present invention is, it is provided that a kind of food stage hydrolysis PA66/PPO (that is: nylon66 fiber/poly-
Phenylate) composite, it has high heat-resisting, the feature of high tenacity, and abundant raw material source, production technology is the most controlled, production operation
Convenient.
In order to solve above-mentioned technical problem, the present invention proposes techniques below scheme: a kind of food stage hydrolysis PA66/PPO
Composite, is made up of the following component calculated in parts by weight:
Described PA66 resin is formed with hexamethylene diamine condensation polymerization by adipic acid；

Part, toughener 15～18 parts, heat stabilizer 0.2-0.3 part, lubricant 0.2～0.3 part, anionic additive 2～3 parts；
Step 2: said components is mixed 3-7 minute in moderate-speed mixers；
Step 3: then each component mixed for step 2 is melt extruded through double screw extruder, pelletize；Double screw extruder
Process conditions are: double screw extruder one district temperature is 240～300 DEG C, and two district's temperature are 240～300 DEG C, and three district's temperature are
240～300 DEG C, four district's temperature are 240～300 DEG C, five districts 240～300 DEG C, and compound time of delivery in screw rod is 10～30
Second.
Compared with prior art, the present invention has a following beneficial effect:
The present invention uses commercially available PA66 resin, the former powder of PPO, adds self-control phase volume, self-control toughener, heat stabilizer, bears
PA66/PPO is modified processing by the auxiliary agent such as ionic additive, lubricant；Wherein self-control compatilizer is molten by PA66 and PPO two kinds
The resin that solution degree parameter differs greatly fuses mutually, adds self-control toughener and composite can be made to have the toughness of excellence；Thermally-stabilised
Agent can suppress non-yellowing in curler product in use high temperature or high humidity environment；Lubricant makes product surface light and allows
Additive is dispersed in PA66/PPO alloy, and anionic additive adds the quiet of curler in use cation generation
Electricity, the main component of anionic additive is that submarine mine stone powder has played filling effect simultaneously, reduces the shrinkage factor of goods.
It is the most controlled that the present invention prepares production technology, produces easily operation.
In the present invention, PA66 is continuous phase, and PPO is dispersion phase, makes full use of the performance that PAA66 ductility is excellent, and PPO is excellent
Different high-fire resistance.The PA66/PPO alloy prepared was 220 DEG C of oven for baking 1 hour, and cooling 1 is little in atmosphere
Time, such action behavior is 1 circulation, and the composite energy ageing cycle that we produce still keeps excellent toughness for 12 times.
High heat-resisting high tenacity PA66+PPO alloy PP Pipe Compound can be widely used in the electric equipment products such as cosmetology now.

× (13 ± 0.5) × (1.5 ± 0.1), i.e. 220 DEG C in an oven baking after 1 hour 1.5mm batten taken out and puts in atmosphere
Cool down 5 minutes, by the toughness after bending spline method perception material aging.
Embodiment 1-7 raw material weight number and the composite property table made
The former powder of PPO, self-control PPO-g-MAH, the use of self-control SEBS-g-MAH are non-quantitative application in this patent, with
The increase of PPO former powder consumption, the hot strength of material reduces, and reason is that the hot strength of the former powder of PPO used only has 62MPa,
EPR27 hot strength is that 75MPa. toughener SEBS-g-GMA content increases, and hot strength also decreases, notch impact strength
Raise.
220 DEG C aging refers to that curler is energized 40 minutes, and cooling down 20 minutes is aging one hour, then is energized 40 minutes,
Cool down 20 minutes.Testing through infrared temperature measurement gun, the maximum temperature of curler heating bar is 220 DEG C, learns from experimental data,
Along with PPO content increases, ageing time extends, but the notch impact strength of material decreases.Reason is PPO molecular structure
Middle phenyl ring is large number of, and the rigidity causing the former powder of PPO is big, affects the toughness of PA66/PPO alloy.
