技术领域 FIELD

[0001] 本发明涉及高分子组合物技术领域,尤其是涉及一种具有改进熔体流动性以及良好机械性质的阻燃性组合物,该阻燃性组合物的制备方法及其应用。 [0001] The present invention relates to a polymer composition Field of technology, particularly to an improved melt flow properties and good mechanical properties of the flame retardant composition, preparation and use of the flame retardant composition.

背景技术 Background technique

[0002] 包含聚碳酸酯(PC)、聚酯和弹性抗冲改性剂例如丙烯腈-丁二烯-苯乙烯共聚物(ABS)或丙烯酸甲酯-丁二烯-苯乙烯共聚物(MBS)的热塑性组合物是已知的。 [0002] A polycarbonate (PC), polyesters, and elastomeric impact modifiers such as acrylonitrile - butadiene - styrene copolymer (ABS) or methyl acrylate - butadiene - styrene copolymer (MBS ) thermoplastic compositions are known. 向热塑性组合物(又名PC/聚酯合金,PC/polyester alloy)中加入抗冲改性剂不仅导致改进的抗冲击性,而且导致改进的整体机械性能。 The thermoplastic composition (also known as PC / polyester alloy, PC / polyester alloy) was added impact modifier not only results in improved impact resistance, but also result in improved overall mechanical properties. 后一种效果归结于非晶性的PC和结晶性聚酯通过抗冲改性剂介导而具有更好的相容性。 The latter effect is attributed to the amorphous polyester and the crystalline PC has better compatibility mediated by an impact modifier.

[0003] PC/聚酯合金用于生产薄膜、纤维、挤出片材、多层层压制件和模制品,尤其用于仪器仪表壳体、汽车主体板和其它用于汽车的部件元件、电气和电子应用。 [0003] PC / polyester alloy for the production of films, fibers, extruded sheets, multi-layer extrusions and moldings, in particular for housing instruments, automobile body panels and other parts for an automobile components, electrical and electronic applications. 优良的机械强度、 耐冲强度和阻燃性以及易于加工是PC/聚酯合金的一些关键特征,这促使其用于上述应用中。 Excellent mechanical strength, flame retardancy and high impact strength and ease of processing are some key features of PC / polyester alloy, which causes for the above applications.

[0004] 近年来,尤其针对将PC/聚酯合金用作电气或电子部件材料,要求是防火安全的,因此所述材料经常被要求具有高度阻燃性以通过UL - 94 (美国保险人实验室标准)VO等级。 [0004] In recent years, in particular for the PC / polyester alloy material for electrical or electronic components, fire safety requirements, and therefore the material is often required by a high degree of flame retardancy to UL - 94 (U.S. insurer Experiment standard room) VO rating. 因此已经开发出各种阻燃剂,并对其进行研究,以赋予热塑性组合物高度阻燃性。 Thus various flame retardants have been developed, and subjected to studies in order to impart highly flame retardant thermoplastic composition. 出于环境和健康的考虑,本行业优选使用无卤阻燃剂。 For environmental and health concerns, the industry is preferable to use halogen-free flame retardants. 在许多不同种类的无卤阻燃剂中,有机磷酸酯最近备受青睐。 In many different types of halogen-free flame retardants, organic phosphate recently favored.

[0005] 例如,CN101104731A公开了一种阻燃性组合物,其包含50 - 85% PC,5-30% PET、 [0005] For example, CN101104731A discloses a flame-retardant composition, comprising 50 - 85% PC, 5-30% PET,

2 - 15 %核-壳接枝共聚物、5 - 15 %含磷阻燃剂,以及其它任选成分。 2 - 15% of the core - shell graft copolymer and 5 - 15% of the phosphorus-containing flame retardant, and other optional ingredients. 所述含磷阻燃剂选自磷酸三甲酯、磷酸三乙酯、磷酸三苯酯和/或间苯二酚二(磷酸二苯酯)(RDP)。 The phosphorus flame retardant is selected from trimethyl phosphate, triethyl phosphate, triphenyl phosphate and / or a resorcinol bis (diphenyl phosphate) (RDP). 所述组合物具有优良的阻燃性,UL94 V - O (样条厚度为1.6毫米)。 The composition has excellent flame retardancy, UL94 V - O (spline thickness of 1.6 mm). 在该公开文献中没有提到可将流动改性剂作为添加剂加入所述组合物。 In this publication no mention flow modifiers may be added to the composition as an additive.

[0006] 然而,当热塑性组合物用各种添加剂例如抗冲改性剂和阻燃剂等以相对高浓度配制时,可能导致熔体流动性显著下降。 [0006] However, when the thermoplastic composition such as impact modifiers and flame retardants formulated at relatively high concentrations, various additives may cause a significant decrease of melt flow. 尤其,对于加工具有带有小流动横截面的复杂而精细设计的部件,就发现常规阻燃剂PC/聚酯合金的流动性是不足的。 In particular, the machining with a small flow cross section having a complex and fine design components found flowability conventional flame retardant PC / polyester alloy is insufficient.

[0007] CN101050302A公开了一种阻燃性PC /聚对苯二甲酸丙二酯(PTT)合金,其包含50-60重量% PC和20 - 30重量% PTT,具有5 - 7重量%芳族有机磷酸酯和2 - 4重量%聚甲基苯基硅酮的阻燃性混合物,具有4 - 6重量% MBS和3 - 5重量%苯乙烯-马来酸酐(SMAH)的增容剂混合物,以及其它添加剂。 [0007] CN101050302A discloses a flame-retardant PC / poly (PTT) terephthalate alloy which comprises 50-60 wt% PC and 20--30% by weight of the PTT, having 5--7% by weight of an aromatic organic phosphates and 2 - 4% by weight of flame retardant mixture of poly methylphenyl silicone, having 4 - 6 wt% MBS 3 and - 5% by weight of styrene - maleic anhydride compatibilizer mixture (SMAH) of and other additives. 该阻燃性混合物的聚甲基苯基硅酮据称可减少芳族有机磷酸酯的用量(芳族有机磷酸酯与聚甲基苯基硅酮的最佳比例为6 : 3),同时仍满足UL - 94 V - O的要求(样条厚度为0.8毫米),还可改进所述合金的熔体流动性(熔体流动指数为18 g / 10 min),使其相当于类似的进口产品。 The flame retardant poly methylphenyl silicone mixture are said to reduce the amount of aromatic organic phosphoric acid ester (the optimum ratio of aromatic organic phosphates and poly-6-methylphenyl silicone: 3), while still to meet UL - 94 V - O request (spline thickness of 0.8 mm) of the alloy also improves melt flowability (melt flow index 18 g / 10 min), it is equivalent to similar imports .

[0008] 本发明提供了一种阻燃性PC / PTT组合物,其如下性质甚为优异:阻燃性、机械强度和可模塑性,在此公开的本发明组合物是通过共混有效量的多元醇作为熔体流动改性剂以实现高流动性而不牺牲其机械性能。 [0008] The present invention provides a flame-retardant PC / PTT composition very excellent in the following properties: flame retardancy, mechanical strength and moldability, the compositions disclosed herein of the present invention is obtained by blending an effective amount of a polyol as melt flow modifiers to achieve high flowability without sacrificing mechanical properties.

[0096] 从表2的结果,以下结论是显而易见的。 [0096] From the results of Table 2, the following conclusions are readily apparent.

[0097] 从实施例I和对比例I之间的比较可以看出,通过混合O. 05重量%的&)熔体流动改性剂(即季戊四醇)和68. 4%的(a)芳族聚碳酸酯、9. 8%的(b) PTT和5. 9%的(c)抗冲改性剂和13. 7%的(d)有机磷酸酯(即Doher - 7000)获得的阻燃性组合物显示出流动性得到显著改善,体现在旋流数据(增加约20%),并且对机械性能(例如拉伸模量、拉伸屈服应力、挠曲模量和最大挠曲应力)的影响最小。 [0097] As can be seen the comparison between Example I and Comparative Example I the embodiment, by mixing O. 05% by weight of &) a melt flow modifiers (i.e. pentaerythritol) and 68.4% of the (a) aromatic flame retardancy obtained. - polycarbonate, 98 percent (b) PTT and 5.9% of (c) impact modifier and 13.7% (d), organophosphates (i.e. Doher 7000) compositions exhibit significantly improved flowability, data embodied in the cyclone (approximately 20% increase), and the mechanical properties (such as tensile modulus, tensile yield stress, flexural modulus and maximum flexural stress) influence a minimum.

[0098] 从实施例2和对比例2之间的比较可以看出,通过混合O. 08重量%的(e )熔体流动改性剂(即季戊四醇)和58. 8%的(a)芳族聚碳酸酯、14. 2%的(b) PTT和7. 2%的(c)抗冲改性剂和17. 6%的(d)有机磷酸酯(即Doher - 7000)获得的阻燃性组合物显示出流动性得到显著改善,体现在旋流数据(增加约30%),并且对机械性能(例如拉伸模量、拉伸屈服应力、挠曲模量和最大挠曲应力)的影响最小。 [0098] and can be seen from a comparison between Example 2 Comparative Example 2, by mixing O. 08% by weight of (e) a melt flow modifiers (i.e. pentaerythritol) and 58.8 percent of (a) aryl retardant obtained. - aromatic polycarbonate, 142% of the (b) PTT and 7.2% of (c) impact modifier and 17.6% (d), organophosphates (i.e. Doher 7000) compositions exhibit significantly improved flowability, data embodied in the cyclone (about 30% increase), and the mechanical properties (such as tensile modulus, tensile yield stress, flexural modulus and maximum flexural stress) of minimal impact.

[0099] 从对比例3和对比例4之间的比较可以看出,通过将有机磷酸酯(即PX200)的用量从14. 0%降低到9. 3%,并替换为4. 7%的聚苯基甲基硅酮(根据CN101050302A建议的最佳比例),导致PC / PTT组合物(对比例4)不能满足UL94的最低阻燃等级之要求。 [0099] From the comparison of Comparative Example 3 and Example 4 it can be seen between reduced from 14.0% to 9.3% by adding an organic phosphate (i.e. the PX200) used in an amount, and replaced with 4.7% of poly phenyl methyl silicone (the optimum ratio CN101050302A recommended), resulting in PC / PTT composition (Comparative Example 4) can not meet the requirements of flammability rating of UL94 minimum. 另外,在比较对比例4与实施例3之间所增加的流动性,4. 7%聚甲基苯基硅酮显然没有O. 1%的季戊四醇那么有效地增加流动性(对比例4与实施例3之间的比较),后者显示出约25%的熔体流动提高,此点乃体现在其旋流数据上,同时仍保持优异的机械性能和阻燃性。 Further, in comparison between Comparative Example 4 and Example 3 the increase in liquidity, 4.7% poly methylphenyl silicone apparently not O. 1% pentaerythritol so effectively increases flowability (Comparative Example 4 and Embodiment comparison between Example 3), which showed about 25% increase of the melt flow, which point is the data reflected in its swirl, while still maintaining excellent mechanical properties and flame retardancy.

[0100] 从表3的实施例4- 9与对比例5-7之间的比较可以看出,通过混合O. 1%的(e)熔体流动改性剂(即季戊四醇)和各种重量百分比的组分(a)芳族聚碳酸酯、(b) PTT、(c)抗冲改性剂和(d)有机磷酸酯获得的本发明的阻燃性组合物也显示出在阻燃性、流动性和机械性能之间获得了优异的平衡。 [0100] 4-9 and can be seen from the examples in Table 3 for a comparison between the ratio of 5-7, prepared by mixing of O. 1% (e) a melt flow modifiers (i.e., pentaerythritol) and various weight percentages of components (a) an aromatic polycarbonate, the flame retardant composition of the present invention, (b) PTT, (c) impact modifier and (d) an organic phosphate obtained also exhibit the flame retardancy a superior balance between flowability and mechanical properties. 请注意,虽然组合物具有相同含量的熔体流动改性剂(O. I%),但是所获得的旋流数据却随芳族聚碳酸酯的含量减少而增加,这是由于芳族聚碳酸酯比PTT具有较差的固有流动性(intrinsic flowability)。 Note, the melt flow modifiers (O. I%), although a composition having the same content, but they swirl the data obtained with the reduced content of the aromatic polycarbonate is increased, due to the aromatic polycarbonate ester has a poor flowability intrinsic (intrinsic flowability) than PTT.
