Description
[technical field]
The present invention relates to a kind of PA66 complex, be specifically related to a kind of fiberglass reinforced with low temperature resistant high transparency
PA66 complex.
[background technology]
In prior art, PA66 is usually used to make the plastic fittings of the article of everyday use of automobile, household electrical appliances.PA66
Can produce dehydrating phenomena, and being gradually reduced along with ambient temperature at low temperatures, its dehydrating phenomena can be more
Seriously.The reduction of moisture content causes PA66 material to be more susceptible to embrittlement.
In order to improve PA66 resistance to low temperature, conventional method is introducing olefines in PA66 compound system
Or rubber-like toughener.Employing POE grafting horse is just given such as the comparative example 1 in the present invention
Carry out the anhydride (POE-g-MAH) prior art as toughener, but owing to olefines or rubber-like are toughness reinforcing
The refractive index that agent itself has and the refractive index of PA66 own are very remote, so the color of the complex obtained is complete
It is milky.
But, along with improving constantly of people's aesthetic standard, to automobile, the plastic fittings of the article of everyday use of household electrical appliances
Outward appearance also require that more and more higher, there is high glaze, high light, high transparency, the performance such as low temperature resistant becomes must
So trend.Obvious existing PA66 complex cannot meet above-mentioned requirement.
[summary of the invention]
The object of the invention essentially consists in offer one can prevent PA66 under conditions of without toughener
The PA66 complex of low-temperature embrittleness.
It is another object of the present invention to increase the transparency of PA66 complex.
To achieve these goals, it is provided that a kind of glass fiber reinforced PA66 complex with low temperature resistant high transparency,
By accounting for gross weight 9.7～the copolymer nylon of the PA66 of 69.7%, 20～40%, the lubricant of 0.3% and 10～50%
Glass composition, described copolymer nylon is formed by caprolactam, adipic acid, hexamethylene diamine ternary polymerization.
Understand in conjunction with the table one in detailed description of the invention and table two, use the above-mentioned formula of the present invention, be not added with
In the case of entering toughener, the physical property such as its tensile yield strength, bending strength, IZOD notch impact strength
All can reach even to surmount properties when being added with toughener, and transparency is good, it is possible to meet
World today people are for the demand of plastic outward appearance.
On the basis of above-mentioned formula, the present invention also has a following prioritization scheme:
Further, the copolymer nylon of employing should with PA66 refractive index close seemingly.And as refractive index close
Copolymer nylon preferably employs again PA6.66.Copolymer nylon PA6.66 with PA66 is fully compatible, simultaneously copolymerization
Nylon PA6.66 Yu PA66 has refractive index closely, and therefore the two blend alloy has no effect on each other
Refractive index.
Described lubricant is EBS.Due to EBS for PA66 system except having the effect of inside and outside lubrication
Really, have the effect of thinner concurrently simultaneously, therefore to ensure the high transparent of reinforced plastic PA66 complex, excellent
Elect EBS as.
[detailed description of the invention]
Hereinafter, the present invention is described further in conjunction with the embodiments, embodiment be only used for explain and need not
In limiting protection scope of the present invention.
The glass fiber reinforced PA66 complex of the low temperature resistant high transparency in embodiment, by accounting for gross weight 9.7～69.7%
The copolymer nylon of PA66,20～40%, the lubricant of 0.3% and 10～50% glass composition, described
Copolymer nylon is formed by caprolactam, adipic acid, hexamethylene diamine ternary polymerization.
Copolymer nylon is to be formed by caprolactam, adipic acid, hexamethylene diamine ternary polymerization, and the ratio of three monomers is not
With, the performance of the copolymer nylon that polymerization obtains is the most different, if caprolactam content is more than adipic acid and hexamethylene diamine
If the amount of sum, then copolymer nylon should be PA6/PA66 (PA6.66), if caprolactam content is less than oneself
If the amount of diacid and hexamethylene diamine sum, then copolymer nylon should be PA66/PA6 (PA66.6), due to PA6.66
Having longer flexible Long carbon chain than PA66.6, the purpose of the present invention is primarily to improve the resistance to low of PA66
Warm nature energy, does not affect the transparency that reinforced plastic PA66 composite has itself, the most preferably PA6.66 simultaneously.
Copolymer nylon (PA6.66) is fully compatible with PA66, and copolymer nylon (PA6.66) has with PA66 simultaneously
Having refractive index closely, therefore the two blend alloy has no effect on refractive index each other.
Lubricant in described PA66 system, conventional lubricants has: EBS (the double lauramide of ethylene), silicone
Powder, E is cured, due to EBS for PA66 system except having the effect of inside and outside lubrication, have fall concurrently simultaneously
The effect of stick, therefore to ensure the high transparent of reinforced plastic PA66 complex, preferably EBS.
The proportioning of the percentage by weight of embodiment 1-9 and comparative example 1-3 is as shown in Table 1:
The POE-g-MAH that table one is enumerated is POE grafted maleic anhydride, is conventional nylon alkene
Toughening agents, MAH percent grafting: 0.8%.
After PA66, PA6.66 being individually positioned in convection oven at 90 DEG C drying 4 hours, with
POE-g-MAH, EBS, the alkali-free glass fibre percentage by weight as shown in table one carries out mix homogeneously, logical
Cross the parallel dual-screw extruding machine blending extrusion pelletize of routine, get final product 12 samples；12 samples are being roused
It is molded into standard testing batten by injection machine after wind baking oven is dried 4 hours at 100 DEG C,
Each section of temperature of described screw extruder in the same direction is followed successively by: 280 DEG C, 275 DEG C, 270 DEG C, 265 DEG C,
260 DEG C, 255 DEG C, 260 DEG C, 265 DEG C, 275 DEG C, screw speed: 400 revs/min.
Each section of temperature of described injection machine is followed successively by: 280 DEG C, 275 DEG C, 275 DEG C, 275 DEG C.By obtain
Embodiment 1-9 and comparative example 1-3 batten, according to ASTM standard test mechanical property (dry state test), survey
Test result sees table two:
