Abstract
The invention relates to a manufacture process of a cold-resistant flexible high temperature resisting nylon material. The cold-resistant flexible high temperature resisting nylon material is composed of the following components in percentage by weight: 49.5-90% of high temperature nylon, 1-10% of nylon 66, 3-35% of cold-resistant agent, 3-35% of softener, 1-10% of bulking agent, 0.3-1.5% of antioxidant, 0.3-3.5% of heat stabilizer and 0.3-5.5% of other auxiliaries. A green environmental-protection flexible nylon material disclosed by the invention can resist to a low temperature of -40 DEG C, cantilever notch impact strength is about ten times higher than that of common nylon, and moreover, the cold-resistant flexible high temperature resisting nylon material is convenient to produce and purchase, and competitive capacity is greatly improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of cold-resistant flexible high-temperature resistant nylon material manufacture craft.The invention still further relates to the method for making this cold-resistant flexible high-temperature resistant nylon material.
Background technology
At present, application with the alternative natural materials of plastics constantly enlarges in the world, scientist all over the world actively seeks new high-performance thermoplastics and comes alternative metals and timber by various tests, and this also becomes enterprise and strives for more families and the important component part of extending volume growth.
It is possible that the development of high temperature plastics changes into the more microminiaturized lightweight of industrial or agricultural and civilian installation and powerful.High-temperature resistance plastice can bring higher heat resistance for some parts, or simply having substituted raw material metal produces these parts.The device of novel appts and assembly equally also useful high-temperature resistance plastice replace the trend of metal and thermosetting material.These all will strengthen the demand to the high-temperature resistance plastice material, thereby drive the market requirement.
These high-temperature resistance plastice materials can anti-180 ℃ continuous high temperature, and can also keep good dimensional stability.Have excellent long-term and short term thermal performance, can tolerate the high temperature that infrared (IR) reflow ovens of using in the pb-free solder process produces, and under wet environment, provide identical intensity, the chemical resistant properties of brilliance.
But the high-temperature resistance plastice material of all kinds has a common shortcoming in the existing market: impact lowlyer, fragility is obvious, and is especially when the sub-zero temperature environment, more partially crisp.The larger range of application that has limited high temperature plastics alternative metals and timber of this shortcoming.And these the problem to be solved in the present invention just.
Series product of the present invention fully meet European Union's " waste and old electric electric installation " (WEEE) and " objectionable impurities limits the use of instruction " (RoHS) rules and other environmental regulations, can both use the Application Areas that environmental requirement is strict.
Summary of the invention
The object of the invention is to, a kind of environmental protection flexible high-temperature resistant nylon material that resists cold is provided, can tolerates subzero 40 degree low temperature, the socle girder notched Izod impact strength exceeds about nearly ten times than common high-temperature nylon, and production procurement is convenient, greatly improves the competitiveness like this.
Technical scheme provided by the invention is as follows: high-temperature nylon: 49.5-90%; Nylon 66:1-10%; Cold-resistant agent: 3-35%; Softener: 3-35%; Expanding material: 1-10%; Antioxidant: 0.3-1.5%; Thermo-stabilizer: 0.3-3.5%; Other auxiliary agents: 0.3-5.5%;
The preparation method of the cold-resistant flexible high-temperature resistant nylon material of environmental protection of the present invention, comprise the steps: first with high-temperature nylon, nylon 66 and all auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, after in the screw combinations situation that medium tenacity is sheared, add mixing extrusion with cord wood parallel equidirectional two-screw forcing machine again, the water cooling bracing pelletizing makes the cold-resistant flexible high-temperature resistant nylon material of environmental protection through screening and dewatering.
The environmental protection of the present invention flexible high-temperature resistant nylon material that resists cold can tolerate subzero 40 degree low temperature, and the socle girder notched Izod impact strength exceeds about nearly ten times than common high-temperature nylon, and production procurement is convenient, greatly improves the competitiveness like this.
Embodiment
Below be the most preferred embodiment of the cold-resistant flexible high-temperature resistant nylon material of environmental protection of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of environmental protection flexible high-temperature resistant nylon material that resists cold is provided, and is made of by weight high-temperature nylon following composition: 60%; Nylon 66:7%; Cold-resistant agent: 7%; Softener: 15%; Expanding material: 8%; Antioxidant: 1.0%; Thermo-stabilizer: 1.5%; Other auxiliary agents: 0.5%;
First with high-temperature nylon, nylon 66, cold-resistant agent and softener, expanding material, antioxidant, thermo-stabilizer, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 42 length-to-diameter ratios, the combination of medium tenacity shear screw, mixing extrusion; Adopt water cooling bracing pelletizing mode, namely make the cold-resistant flexible high-temperature resistant nylon material of environmental protection through screening and dewatering.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
