Description
Technical Field
The invention belongs to the field of modification of high polymer materials, and particularly relates to a high-impact-resistance toughened nylon material at ultralow temperature and a preparation method thereof.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
Nylon is widely applied engineering plastic, has good mechanical property, heat resistance, wear resistance, chemical solvent resistance, self-lubrication, certain flame retardance and excellent processing property, can be integrally molded into complex structural parts, and is widely applied to the fields of automobiles, electronic and electric appliances, machinery, rail transit, sports equipment and the like. But because the performance of the composite material is influenced by environment and temperature, the composite material can be greatly changed, the development and the application of the composite material are hindered, and the comprehensive performance of the composite material can be obviously improved by modifying the composite material.
With the development of the high-end equipment manufacturing industry which is vigorously promoted by the country, the requirements on various properties of modified nylon and other engineering plastics are higher and higher, but the properties of low temperature resistance, toughness, mechanical strength and the like of most of modified nylon products produced in China are not coordinated, and the specific expression is as follows: the low-temperature resistant and high-toughness product has poor mechanical strength and high mechanical strength, and particularly the impact strength under the ultralow-temperature environment can only reach 10-20% of the impact strength at room temperature. Therefore, it cannot be used or has a shortened service life in an ultra-low temperature environment.
The special engineering plastics used in alpine regions in China and other extreme environments such as south and north poles have high requirements on the balance performance of products, and the existing nylon products have the problems of too poor impact resistance, easy cracking and short service life under the condition of ultralow temperature or the problems of unmatched strength and toughness and other performances, so that the special engineering plastics cannot meet the special requirements of the alpine regions in China on the high impact resistance nylon products.
Disclosure of Invention
In order to overcome the problems, the invention provides a toughened nylon material with excellent comprehensive performance and high impact resistance in an ultralow temperature environment, and the notch impact strength of a simple beam at room temperature is higher than 80kJ/m2The product still has the impact strength of more than 40 percent of the room temperature at the low temperature of-55 ℃, and the ultra-low temperature impact resistance of the product is perfectly improved. Meets the use requirements of special engineering plastics on low temperature resistance in alpine regions and other extreme environments in China.
In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:
the high-impact-resistance toughened nylon material at ultralow temperature comprises the following components in parts by weight: 60-70 parts of nylon resin, 20-30 parts of toughening agent A, 1-5 parts of toughening agent B, 0.1-1 part of antioxidant, 0.2-2 parts of light stabilizer and 0.5-2 parts of processing aid;
wherein the toughening agent A is a polyolefin elastic resin grafted by maleic anhydride;
the toughening agent B is an environment-friendly plasticizer of citric acid esters or epoxy.
The research of the application finds that: under the low temperature condition, the interaction of the intermolecular force of the toughening agent A and the toughening agent B can be effectively utilized to increase the force required by the material when the material is damaged, thereby improving the impact resistance of the material under the low temperature environment.
In some embodiments, the following components are included in parts by weight: 60-65 parts of nylon resin, 20-25 parts of toughening agent A, 1-3 parts of toughening agent B, 0.1-0.5 part of antioxidant, 0.2-1 part of light stabilizer and 0.5-1.2 parts of processing aid.
In some embodiments, the following components are included in parts by weight: 65-70 parts of nylon resin, 25-30 parts of toughening agent A, 3-5 parts of toughening agent B, 0.5-1 part of antioxidant, 1-2 parts of light stabilizer and 1.2-2 parts of processing aid.
The research finds that: as a dispersed phase, elastomer particles need to reach a certain distance to effectively toughen nylon, and the crosslinking degree, viscosity and grafted functional groups of the elastomer also have an influence on the toughening effect, so that in some embodiments, the toughening agent A is a mixture of one or more of PE-g-MAH, PP-g-MAH or POE-g-MAH, and the toughening and low-temperature impact resistance of the nylon are improved.
In some embodiments, the toughening agent B is tributyl citrate, trioctyl citrate, acetyl tributyl citrate, acetyl trioctyl citrate, and a mixture of one or more of epoxidized soybean oil, epoxy acetyl methyl linoleate, epoxy butyl furoate, epoxy butyl pupate oleate, epoxy octyl soybean oleate, 9, 10-epoxy octyl stearate. By adding a small amount of the toughening agent B, the impact on the tensile property of the material is small, and the impact resistance of the material is improved in a low-temperature environment.
The research finds that: because the nylon material contains amide groups with stronger polarity, and is easily influenced by high temperature, ultraviolet rays, moisture and other environments, the macromolecular chains generate reactions such as crosslinking, chain scission, isomerization and the like, therefore, in some embodiments, the antioxidant is one or a mixture of phenols, thioesters and metal ion passivation type antioxidants; effectively controls the aging degradation of the nylon resin caused by high temperature in the processing, and obviously improves the problems of yellowing and performance reduction of the nylon resin in the processing and using processes.
The nylon material is exposed to sunlight for a long time or placed under strong fluorescence for a short time, and because ultraviolet energy is absorbed, an automatic oxidation reaction is caused, so that nylon resin is degraded, and a product is discolored, crisp and has reduced performance. Therefore, in some embodiments, the light stabilizer is one or a mixture of carbon black, zinc chloride and titanium dioxide, and can effectively protect the nylon material from being damaged by ultraviolet rays and improve the long-term stability of the nylon material.
In order to avoid the influence of high temperature, ultraviolet and moisture on the nylon performance during processing, the adverse interaction reaction between the nylon and the additive is reduced. Thus, in some embodiments, the processing aid is an EBS lubricant, oleamide, or erucamide, which effectively improves the processability of nylon resins and effectively increases the processing flowability of nylon without increasing the processing temperature.
The source and type of nylon resin is not particularly limited, and in some embodiments, the nylon resin is nylon 6, nylon 66, or a mixture thereof having a relative viscosity of 2.0 to 3.4, which improves the toughness and low temperature impact resistance of the nylon.
The invention also provides a preparation method of the high-impact-resistance toughened nylon material at ultralow temperature, which comprises the following steps:
and (3) uniformly mixing the nylon resin, the toughening agent A, the toughening agent B, the antioxidant, the light stabilizer and the processing aid, and carrying out twin-screw extrusion molding to obtain the nylon/light stabilizer. The preparation method of the high-impact-resistance toughened nylon material at ultralow temperature has the advantages of simple process, easy operation and high production efficiency.
In some embodiments, the twin-screw extrusion molding process comprises: the rotating speed of the feeding screw is 40-60r/min, and the rotating speed of the main screw is 400-; the first to third zone temperatures are: the temperature of the fourth zone to the sixth zone is 220-270 ℃: 230-280 ℃ and seven-nine zone temperature: 220 to 280 ℃. The prepared ultra-low temperature high impact resistant toughened nylon material has excellent cold resistance, the notch impact strength at the low temperature of-55 ℃ can be kept above 40% of the room temperature data, and the product has good and stable comprehensive performance.
In some embodiments, the twin screw extruder is processed by: the first to third zone temperatures are: the temperature of the fourth zone to the sixth zone is 220-240 ℃: 230-250 ℃ and seven-nine zone temperature: 220-250 ℃, the rotating speed of the main screw is 500 revolutions per minute, and the rotating speed of the feeding screw is 50 revolutions per minute.
