Abstract
The present invention relates to a kind of resistant, toughened nylon material manufacture crafts, are made of by weight following component, high-temperature nylon: 90-95%；Nylon66 fiber: 2-4%；Cold-resistant agent: 3-5%；Softener: 2-5%；Expanding material: 1-2%；Antioxidant: 0.1-1.0%；Heat stabilizer: 0.1-1.0%；Other auxiliary agents: 0.3-5.5%.The environmentally protective resistant, toughened nylon material of the present invention is resistant to subzero 40 degree of low temperature, and Izod notched impact strength is higher by nearly ten times or so than common high-temperature nylon, and production procurement is convenient, greatly improves the competitiveness in this way.
Description
Technical field
The present invention relates to a kind of organic polymer composites, are to be related to a kind of resistant, toughened nylon more specifically
Material manufacture craft.The invention further relates to the methods for making this resistant, toughened nylon material.
Background technique
Currently, constantly being expanded with the application of plastics substitution natural material in the world, scientist all over the world passes through various
Test finds new high-performance thermoplastics actively to substitute metal and timber, and this also become enterprise strive for more families and
The important component extended volume growth.
The development of high temperature plastics makes industrial or agricultural and civilian installation lightweight and powerful chemical conversion be miniaturized more as can
Energy.High-temperature resistance plastice can bring higher heat resistance for certain components, or simply produce instead of raw material metal
These components.The device and component of novel device equally also useful high-temperature resistance plastice replace metal and thermosetting material trend.
These will all increase the demand to high-temperature resistance plastice material, to drive the market demand.
These high-temperature resistance plastice materials can be with resistance to 180 DEG C of continuous high temperature, and is also able to maintain good dimensional stability.
With excellent long-term and short-term hot property, can be resistant to caused by (IR) reflow ovens infrared used in pb-free solder process
High temperature, and identical intensity is provided in wet condition, brilliant chemical resistance.
But in existing market the high-temperature resistance plastice material of all kinds have the shortcomings that one it is common: impact it is lower, it is crisp
Property is obvious, and especially in sub-zero temperature environment, more biasing is crisp.This disadvantage is larger to limit high temperature plastics substitution metal and wood
The application range of material.And these are exactly the problem to be solved in the present invention.
Series of products of the invention fully comply with European Union " waste and old electric electrical equipment " (WEEE) and " harmful substance limits the use of finger
Enabling " (RoHS) regulation and other environmental regulations, the application field stringent to environmental requirement can use.
Summary of the invention
The object of the present invention is to provide a kind of environmentally protective resistant, toughened nylon materials, are resistant to subzero 40
Spend low temperature, Izod notched impact strength is higher by nearly ten times or so than common high-temperature nylon, and production procurement is convenient, in this way compared with
Competitiveness is improved greatly.
Technical solution provided by the invention is as follows: high-temperature nylon: 90-95%；Nylon66 fiber: 2-4%；Cold-resistant agent: 3-5%；
Softener: 2-5%；Expanding material: 1-2%；Antioxidant: 0.1-1.0%；Heat stabilizer: 0.1-1.0%；Other auxiliary agents: 0.3-
5.5%.
The preparation method of environmentally protective resistant, toughened nylon material of the present invention, including the following steps: first will be high
Warm nylon, nylon66 fiber and all auxiliary agents proportionally weigh after in batch mixer mixed on low speed 10 minutes, after use building block system again
Mixing extrusion, water cooling bracing pelletizing warp are added in the screw combinations that moderate strength is sheared for parallel equidirectional two-screw extruder
It crosses screening and dewatering and resistant, toughened nylon material is made.
The resistant, toughened nylon material of the present invention, is resistant to subzero 40 degree of low temperature, Izod notched impact strength ratio
Common high-temperature nylon is higher by nearly ten times or so, and production procurement is convenient, greatly improves the competitiveness in this way.
Specific embodiment
It is the most preferred embodiment of environmentally protective resistant, toughened nylon material of the present invention below, does not therefore limit
Protection scope of the present invention.
Embodiment one, provides a kind of resistant, toughened nylon material, is made of by weight following component, high-temperature nylon:
89.5%；Nylon66 fiber: 3%；Cold-resistant agent: 3%；Softener: 2%；Expanding material: 1%；Antioxidant: 0.5%；Heat stabilizer:
0.5%；Other auxiliary agents: 0.5%.
First by high-temperature nylon, nylon66 fiber, cold-resistant agent and softener, expanding material, antioxidant, heat stabilizer, other help
Agent proportionally weigh after in batch mixer mixed on low speed 10 minutes, batch mixer use mixed on low speed, paddle should be between barrel
For gap less than 0.5 centimetre, supplementary material mixed effect answers visual various particles and powder substantially uniform, without obvious agglomerate or gathers；
Double screw extruder uses 42 draw ratios, the combination of moderate strength shear screw, mixing extrusion；Using water cooling bracing pelletizing mode,
Environmentally protective resistant, toughened nylon material is obtained by screening and dewatering.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those skilled in the art within the technical scope disclosed by the invention, can without the variation that creative work is expected or
Replacement, should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be limited with claims
Subject to fixed protection scope.
