Description
Technical Field
The invention relates to the field of polymer composite materials, in particular to a flame-retardant reinforced high-temperature nylon material and a preparation method thereof.
Background
As common high-temperature nylon, the poly (hexamethylene terephthalamide) copolymer (PA 6T-66) has the excellent performance of aromatic nylon and the processability of aliphatic nylon, is a material with excellent performance, and is widely applied to the fields of electronic appliances, LED illumination, automobile industry and the like. In order to improve the flame retardant property of the high-temperature nylon, a flame retardant is often required to be added into the nylon resin to realize the fireproof function of the nylon. In the prior art, brominated flame retardants are added into high-temperature nylon to realize flame retardance, and Chinese patent CN101921473A discloses a reinforced flame-retardant high-temperature nylon which is prepared from the following raw materials in parts by weight: 55% -80% of polyphenyl diamide, 20% -45% of glass fiber, 0.1% -1.2% of Bulgmann antioxidant, 10% -35% of polybrominated styrene and 3-15% of antimonous oxide. Chinese patent CN104292825a discloses a flame-retardant reinforced high-temperature nylon composite material, which is prepared by blending the following raw materials in parts by weight: 25-65 parts of PPA, 3-15 parts of PA66, 15-50 parts of glass fiber, 15-22 parts of brominated flame retardant, 4-10 parts of metal oxide flame retardant, 0.4-1 part of antioxidant, 0.1-1 part of lubricant and 0.1-1 part of coupling agent. Chinese patent CN 106995607A discloses a halogen flame retardant high temperature nylon composition and a method for preparing the same. The composition provided by the invention comprises the following components in parts by weight: 40-65 parts of high-temperature nylon, 15-25 parts of halogen flame retardant, 2-10 parts of zinc stannate, 0-40 parts of glass fiber and 0.5-2 parts of other processing aids. Chinese patent CN 108250741A discloses a corrosion-resistant high temperature-resistant flame-retardant nylon composite material and a preparation method thereof, the composite material comprises: 30-90 parts of high temperature resistant nylon, 0-60 parts of reinforcing fiber, 5-30 parts of brominated flame retardant, 1-10 parts of zinc borate, 0.1-8 parts of silicon powder, 0.1-0.8 part of antioxidant and 0.1-0.8 part of lubricant. However, the processing temperature of the flame-retardant reinforced high-temperature nylon is up to 330 ℃, and nylon materials are easily degraded by brominated flame retardants, antimony compounds, zinc borate and other shadows in the processing process, so that the mechanical properties of the materials are lost, and particularly, the properties of products obtained after the materials are recycled and processed for the second time are obviously reduced, and the downstream products are at risk for use.
Disclosure of Invention
The invention aims to overcome the defects of the technology, and provides a flame-retardant reinforced high-temperature nylon material, a preparation method and application thereof.
The aim of the invention can be achieved by the following technical scheme:
a flame-retardant reinforced high-temperature nylon material consists of the following materials in parts by weight:
further preferably, the flame-retardant reinforced high-temperature nylon material consists of the following materials in parts by weight:
the high-temperature nylon is poly (hexamethylene terephthalamide) copolymer (PA 6T-66) obtained by copolymerizing terephthalic acid, adipic acid and hexamethylene diamine, and the melting point is 295-315 ℃.
The glass fiber is chopped glass fiber, the diameter is 9-12 mu m, and the length is 3-4.5mm.
The mass ratio of the calcium laurate to the 2, 3-diphenyl indole is 1:1-1:3;
the auxiliary agent is antioxidant 1098 and lubricant PTEs, wherein the weight part of the antioxidant 1098 is 0.1-0.5 part, and the weight part of the lubricant PTEs is 0.2-1.0 part.
The preparation method of the flame-retardant reinforced high-temperature nylon material comprises the following steps:
feeding the high-temperature nylon base material, brominated polystyrene, zinc borate, calcium laurate, 2, 3-diphenyl indole and an auxiliary agent through a main feeding port of a double-screw extruder, adding glass fibers through side feeding, fully melting and plasticizing the materials under the conveying and shearing actions of double screws, and bracing, cooling and granulating to obtain the flame-retardant reinforced high-temperature nylon material.
The flame-retardant reinforced high-temperature nylon material provided by the invention has excellent mechanical property, flame retardant property and processability, and the retention rate of the mechanical property of the material after repeated processing is high.
The invention provides an application of a flame-retardant reinforced high-temperature nylon material in preparing electronic and electric connector components.
Compared with the prior art, the invention has the following advantages:
because the high-temperature nylon has a high melting point, the high-temperature nylon material needs to be subjected to a high-temperature environment in the flame-retardant modification process, but the high-temperature nylon is easily degraded under the action of a brominated flame retardant under the high-temperature condition, so that the mechanical property of the material is reduced, and the downstream product is in failure risk. According to the invention, the brominated polystyrene is adopted as a halogen flame retardant, the zinc borate is adopted as a synergistic flame retardant, and the calcium laurate is introduced, so that strong acid substances such as hydrogen bromide and the like generated by decomposition of the brominated polystyrene under a high-temperature condition can be effectively slowed down, and meanwhile, the structure stability of the flame-retardant reinforced high-temperature nylon can be further improved by compounding the 2, 3-diphenyl indole, so that the high-temperature nylon has high performance retention rate after repeated processing for many times.
According to the invention, the flame-retardant reinforced high-temperature nylon material is stabilized by the synergistic effect of the calcium laurate and the 2, 3-diphenyl indole, so that the flame-retardant reinforced high-temperature nylon material has excellent mechanical property, flame retardant property and processability, and the retention rate of the mechanical property of the material after repeated processing is high.
Detailed Description
The invention is further illustrated by the following examples:
high temperature nylon PA6T-66 (Zhejiang Xinli, SH1240, melting point 310 ℃), brominated polystyrene (Shandong brothers, 7010), chopped glass fiber (boulder, alkali-free chopped glass fiber, diameter 9-12 μm, length 3-4.5 mm), lubricant PETs (commercially available), antioxidant 1098 (Basoff), zinc borate (Lituo), calcium laurate (commercially available), 2, 3-diphenylindole (commercially available).
Examples 1 to 5 and comparative examples 1 to 3
Feeding the high-temperature nylon base material, brominated polystyrene, zinc borate, calcium laurate, 2, 3-diphenyl indole and an auxiliary agent through a main feeding port of a double-screw extruder, adding glass fibers through side feeding, fully melting and plasticizing the materials under the conveying and shearing actions of double screws, and bracing, cooling and granulating to obtain the flame-retardant reinforced high-temperature nylon material.
The melting plasticizing temperature in the double screw extruder is 320-335 deg.c, and the screw rotation speed is 400-600 rpm.
The material proportions of examples 1-5 and comparative examples 1-3 are shown in Table 1.
TABLE 1
The obtained granules are molded into corresponding sample bars according to ISO test standards, and then are placed for 24 hours under the environment of 23+/-2 ℃ and 50+/-5% relative humidity for testing; tensile strength was measured according to ISO527 standard; flexural strength was measured according to ISO178 standard; the Charpy (Charpy impact test) notched impact strength was measured according to ISO 179; the melt index was measured at 330℃under a load of 2.16 kg.
Multiple processability evaluations: after the high-temperature nylon particles are subjected to injection molding to form corresponding sample strips, the sample strips are subjected to crushing treatment, the obtained crushed materials are subjected to cyclic injection molding and crushing, the injection molded sample strips after crushing for the third time are tested, the obtained performance values are compared with the performance values of the initial materials, and the performance retention rate is calculated in%. And comparing the melt index after three times of crushing with the melt index of the initial material, and calculating to obtain the retention rate of the melt index in percent.
The results obtained from the test are shown in Table 2.
TABLE 2
The flame-retardant reinforced high-temperature nylon materials obtained in examples 1-7 have excellent mechanical properties, flame retardant properties and processability, and the retention rate of mechanical properties of the materials after repeated processing is high.
Comparative examples 1 to 5
Comparative examples 1-2 differ from examples 1-4 in that no calcium laurate or 2, 3-diphenylindole was added to comparative example 1, and only calcium laurate was added to comparative example 2, resulting in poor thermal stability of the high temperature nylon material during processing, resulting in serious performance loss after multiple processing of the material.
The difference between example 5 and comparative example 3 is that the calcium laurate and 2, 3-diphenylindole are compounded and cooperated in example 5, the effect is obvious compared with the effect of independently adding 2, 3-diphenylindole in comparative example 3, and the material has better heat resistance and performance retention rate.
Examples 6-7 and comparative examples 4-5 differ in that the compounding of calcium laurate and 2, 3-diphenylindole has a strict mass fraction and ratio, and excessive mass fraction addition or mass ratio mismatch does not significantly improve the heat resistance of the high temperature nylon.
The foregoing is merely illustrative of specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the design concept shall fall within the scope of the present invention.
