Abstract
The invention discloses a kind of high flowing high performance nylon modified material, the components including the following mass percent for accounting for modified material gross mass: 70%~97% PA6 or PA66；0.1%~10% cumyl peroxide；0.2%~20% Triallyl isocyanurate.After function ingredients of the present invention by increasing cumyl peroxide and Triallyl isocyanurate, can maintain nylon material before modified mechanical property it is constant under the premise of, significantly increase the melt index of modified nylon material.
Description
Technical field
The present invention relates to polymeric material fields, more particularly, to a kind of high flowing high performance nylon modified material.
Background technique
Nylon 6 (PA6 or polyamide 6) and nylon66 fiber (PA66 or polyamide 66) are the engineering plastics of excellent combination property
Material has the characteristics such as intensity height, the good, good toughness of chemical corrosion resistance, is generally used for auto parts and components, mechanical part, electronics electricity
The products such as device product, engineering accessory.With the miniaturization of automobile, the high performance of electronic electric equipment, mechanical equipment lightweight
Progress faster, demand to nylon will be bigger.When being processed using Shooting Technique, it is desirable that raw material have higher flowing
Property, in order to be processed into complicated workpiece, while the production time can be shortened with quick injection molding, improve production efficiency, relatively
Reduce production cost.
Although PA6 or PA66 is remarkably improved its rigidity and other mechanical properties after filling, glass fiber reinforcement,
It is that enhanced modified materials mobility is deteriorated, shock resistance is poor, product surface is coarse, floating fine more, system cannot be met well
The injection molding of part and performance and appearance requirement.Therefore, in order to meet the injection molding performance of product, intensity, shock resistance,
The requirement such as appearance, its application field of further expansion, there is an urgent need to develop height flowing, the PA6 of strong mechanical performance or PA66 are modified
Material.
Summary of the invention
It is an object of the invention to overcome drawbacks described above of the existing technology, provide a kind of high performance A6 of high flowing or
PA66 modified material.
To achieve the above object, technical scheme is as follows:
A kind of high flowing high performance nylon modified material, which is characterized in that including the following matter for accounting for modified material gross mass
Measure the component of percentage:
70%~97% PA6 or PA66；
0.1%~10% cumyl peroxide；
0.2%~20% Triallyl isocyanurate.
Preferably, further include glass, miberal powder, fire retardant, heat stabilizer, nucleating agent, lubricant, coupling agent, in toner
One or more composite assistants.
Preferably, the melt index range of the PA6 or PA66 material is 10 grams/10 minutes~90 grams/10 minutes.
It can be seen from the above technical proposal that the present invention is by increasing cumyl peroxide and triallyl isocyanide urea
After the function ingredients of acid esters, can maintain nylon material before modified mechanical property it is constant under the premise of, significantly increase modification
The melt index of nylon material afterwards.Furthermore it is also possible to according to specific needs, be added glass, miberal powder, fire retardant, heat stabilizer, at
Other auxiliary agents such as core agent, lubricant, coupling agent, toner prepare various high flowing Modifed Nylon Products.
Specific embodiment
Specific embodiments of the present invention will be described in further detail below.
It is an object of the invention to not lose the mechanical property such as the shock resistance of PA6 or PA66 material, bending strength, tensile strength
Under the premise of energy, enhance the mobility (i.e. reduction viscosity) of PA6 or PA66 material, so that modified material can be fitted preferably
Answer Shooting Technique.
The modifying composition that the present invention uses includes organic peroxide cumyl peroxide (DCP) and coagent triolefin
Propyl isocyanuric acid ester (TAIC) can effectively enhance mobility and keep good mechanical property.
Especially in addition to above-mentioned group, glass, miberal powder, fire retardant, heat stabilizer, nucleating agent, profit can also be added as needed
Other auxiliary agents such as lubrication prescription, coupling agent, toner prepare various high flow modifier products.
Preferably, PA6 or PA66 material be melt index range be 10 grams/10 minutes~90 grams/10 minutes (gram/10 points
Clock, 300 degrees Celsius, 5 kilograms) middle eutectic refer to material.
By above-mentioned component by deal than being uniformly mixed, by weight loss type feeder, twin-screw extrusion is added by certain speed
Machine, is heated to the plasticizing of 150-280 degree, and high flowing high-performance PA6 or PA66 is made in the cooling, pelletizing by sink of the melt of extrusion
Modified material.
Tables 1 and 2 lists PA6 and PA66 modified material comparative example and each specific embodiment component percentages and system respectively
The performance parameter of the modified material obtained.
Embodiment #1 and #6 are comparative example, and organic peroxide cumyl peroxide (DCP) and coagent are not added
Triallyl isocyanurate (TAIC).
#2~#5, #7~#10 are respectively specific embodiment, as can be seen from Table 1:
(1) addition of DCP and TAIC can effectively improve melt index, i.e. enhancing mobility；
(2) additional amount of DCP and TAIC is higher, and mobility is better；
(3) it is preferably 1%~7.5% that DCP mass, which accounts for the mass percent of modified material gross mass, and especially preferably 5%
~7.5%；
(4) it is preferably 2%~15% that TAIC mass, which accounts for the mass percent of modified material gross mass, and especially preferably 10%
~15%；
(5) after mobility increase, material is also able to maintain relatively good mechanical property.
