Abstract
The invention relates to an ablation-resistant polyphenyl ether composition and a preparation method thereof. The invention can obviously improve the ablation resistance of the polyphenyl ether by introducing the special polyamide resin and a proper amount of flame retardant, and has excellent mechanical property and good market application prospect.
Description
Technical Field
The invention belongs to the field of modified plastics, and particularly relates to an ablation-resistant polyphenyl ether composition and a preparation method thereof.
Background
The polyphenyl ether composition has the advantages of excellent flame retardant property, high rigidity, light density and the like, so that the polyphenyl ether composition is widely applied to power battery packs. However, the conventional polyphenylene ether composition has poor ablation resistance, and cannot meet the requirements of external fire and thermal runaway tests in GB 38031 Power storage battery safety requirements for electric vehicles. So that its application is limited. For example, the upper cover of the power battery pack still uses thermosetting materials such as SMC at present to meet the requirement of ablation resistance. However, SMC and other materials have high specific gravity, low production efficiency, no recyclability and high comprehensive cost. It is therefore desirable in the industry to develop ablation resistant polyphenylene ether compositions that improve manufacturing efficiency and reduce overall cost.
Disclosure of Invention
The invention aims to solve the technical problem of providing an ablation-resistant polyphenyl ether composition and a preparation method thereof, wherein the ablation-resistant polyphenyl ether composition can obviously improve the ablation resistance of polyphenyl ether, and has excellent mechanical properties and good market application prospect.
The invention provides an ablation-resistant polyphenyl ether composition which comprises the following components in parts by weight:
wherein the polyamide resin contains terephthalic acid, and the total mass content of the terephthalic acid in the polyamide resin is 10-30%.
In the invention, the total mass content proportion of the terephthalic acid in the polyamide resin can be determined by a method of establishing a quantitative proportion by a terephthalic acid standard sample through pyrolysis gas chromatography-mass spectrometry.
Preferably, the phosphorus-containing flame retardant has a phosphorus content of 10% to 100%. In the present invention, the phosphorus content of the phosphorus-containing flame retardant can be measured by ion chromatography.
Preferably, 0.25. + -. 0.0002g of PPE resin is dissolved by adding 50mL of concentrated sulfuric acid (96%), and the concentrated sulfuric acid flow time t0 and the sample solution flow time t are measured and recorded in a thermostatic water bath at 25 ℃. The melt viscosity is in the range of 30-55cm 3 (iv) g; the softening point is above 200 ℃. Specifically, the melt viscosity of the PPE resin may be 30cm 3 /g、35cm 3 /g、40cm 3 /g、45cm 3 /g、50cm 3 /g、55cm 3 G, etc.; the softening point of the PPE resin may be: 200 ℃, 205 ℃, 210 ℃, 215 ℃, 220 ℃, 225 ℃, 230 ℃, 235 ℃ and the like.
Preferably, the polyamide resin is at least one of PA10T, PA5T56, PA66, PA6 and PA6T66, wherein at least one resin comprises terephthalic acid monomer.
Preferably, the total proportion of terephthalic acid in the polyamide resin is 15 to 25%. If the proportion of terephthalic acid in the polyamide resin is too low, the ablation requirement cannot be met; too high a proportion of terephthalic acid can lead to deterioration of the processability of the material during production and failure to process at normal processing temperatures.
Preferably, the phosphorus-containing flame retardant is at least one of flame retardants BDP, RDP, TPP, phenoxy polyphosphazene, red phosphorus and diethyl aluminum hypophosphite.
Preferably, the phosphorus-containing flame retardant has a phosphorus content of 10% to 50%. The phosphorus-containing flame retardant is too low in addition ratio and cannot play a flame-retardant role; too high an addition ratio adversely affects impact strength.
Preferably, the invention also comprises at least one of a toughening agent, mineral powder, a lubricant and a coloring agent.
The toughening agent is not particularly limited, and includes, but is not limited to, ethylene-octene copolymer (POE), SEBS, and the like. From the viewpoint of improving toughness, maleic anhydride-grafted POE or maleic anhydride-grafted SEBS is preferable, and the graft ratio is more preferably 0.5 to 2%. The addition amount of the toughening agent is within 10 percent.
The mineral powder is calcium carbonate, talcum powder, mica, kaolin, magnesium hydroxide, burm stone and the like. The addition amount of the mineral powder is within 40 percent.
The lubricant is polyethylene wax, zinc stearate, lithium stearate and the like. The addition amount of the lubricant is within 3 percent.
The colorant is carbon black, titanium dioxide, zinc sulfide, iron oxide red, titanium yellow and the like. The addition amount of the colorant is within 3 percent.
Preferably, the composition comprises the following components in parts by weight:
the invention also provides a preparation method of the ablation-resistant polyphenyl ether composition, which comprises the following steps:
adding the components into a mixer, and uniformly mixing to obtain a uniformly mixed material; and extruding and granulating the uniformly mixed materials through a double-screw extruder to obtain the ablation-resistant polyphenyl ether composition.
The invention also provides application of the ablation-resistant polyphenyl ether composition in a power battery pack.
The mechanism of the invention is as follows:
conventional thermoplastic materials melt and drip rapidly at the elevated temperatures of the ablation test. When glass fibers are added, the melt strength of the material is greatly improved, and the time for dripping at high temperature can be prolonged, but is still insufficient to resist the high temperature. Further ablation can be prevented if the material can rapidly char and form a dense carbon layer during the ablation process. Thus, on the one hand, the melt viscosity of the material is increased and, on the other hand, the rate of addition of carbon is increased.
Conventional polyphenylene ethers have a high melt viscosity and a high rate of carbon formation, but their softening point temperature is too low, and as the temperature rises, the melt viscosity rapidly drops and the material still melts. According to the invention, the polyamide resin containing terephthalic acid with specific content is added into the polyphenyl ether composition, so that the softening temperature of the polyphenyl ether composition is increased, the melt viscosity and the carbon forming rate of the polyphenyl ether composition are greatly increased, and the composition is ensured to have balanced performance; on the basis, a proper amount of phosphorus-containing flame retardant is added, so that the carbon forming rate of the polyphenyl ether and the flame retardant property of the composition are further remarkably improved, and the polyphenyl ether has excellent ablation resistance and excellent mechanical properties.
Advantageous effects
The invention can obviously improve the ablation resistance of the polyphenyl ether by introducing the special polyamide resin and a proper amount of flame retardant, and has excellent mechanical property and good market application prospect.

Glass fiber: the mark is ECS13-03-540H and the share of giant rock.
The compositions of the examples and comparative examples of the present invention were prepared by the following procedure:
adding the components into a mixer, and uniformly mixing to obtain a uniformly mixed material; and extruding and granulating the uniformly mixed materials through a double-screw extruder to obtain the ablation-resistant polyphenyl ether composition. The screw temperature was 280 ℃.
The examples and comparative examples were subjected to the following test methods or test standards:
vicat softening point: the Vicat softening point of the polyphenylene ether compositions was tested with reference to ISO-75-2-2013.
Results of the fire test: the material was processed into 200X 3mm thick sheets and subjected to an external firing test with reference to GB/T38031-2020. And after the test is finished, the phenomena of burn-through, molten drop and the like of the plate are observed. If the plate structure is kept good basically and has no phenomena of burn-through, molten drop and the like, the plate can pass the fire test.
Vertical combustibility: the vertical flammability of test pieces of 1.5mm thickness is tested with reference to UL94 2018. In the test, the combustion performance reaches the UL 94V-0 grade and is marked as OK, and the combustion performance does not reach the UL 94V-0 grade and is marked as NG.

Notched impact strength: the test was carried out with reference to the standard ISO 180-2019.
Formulation and test results (parts by weight) of examples and comparative examples
From the results of examples 1 to 9, it is understood that the present invention can remarkably improve the ablation resistance of polyphenylene ether and at the same time has excellent mechanical properties by incorporating a specific polyamide resin and a specific flame retardant. The vicat softening point of the polyphenyl ether composition can reach 220-250 ℃, the viscosity can reach 1600-2900mPa x s, and the notch impact strength can reach 8.5-13KJ/m 2 。
When too much PPE resin (comparative example 1) or polyamide resin (comparative example 2) was added, the results of the flame test were less than ideal, as compared with examples 1 and 8. As is clear from example 3 and comparative examples 3 and 7, the polyamide resin having an excessively high proportion of terephthalic acid fails to satisfy the ablation requirements; too low a proportion of terephthalic acid results in a deterioration in the processability of the material during production and the inability to process at normal processing temperatures. It is understood from example 3 and comparative example 4 that the ablation resistance is not significantly improved when the phosphorus content of the phosphorus-containing flame retardant is less than 10%. As can be seen from example 8 and comparative examples 5 and 6, the phosphorus-containing flame retardant is added at an excessively low proportion and does not exhibit an ablation resistance; too high an addition ratio adversely affects impact strength. It is understood from example 8, comparative example 8 and comparative example 9 that the viscosity of the material cannot be increased and the burn test cannot be ensured when the glass fiber addition ratio is too low. If the addition ratio is too high, the impact strength of the material may be adversely affected.
