高密封性聚丙烯密封条的加工方法及其密封条 Polypropylene high sealing the sealing strip and the sealing strip machining method

技术领域 FIELD

[0001] 本发明属于机械技术领域,涉及一种高密封性聚丙烯密封条的加工方法及其密封条。 [0001] TECHNICAL FIELD The present invention belongs, and relates to a processing method of a high sealability polypropylene sealing strip of the sealing strip. 背景技术 Background technique

[0002] 聚丙烯,是由丙烯聚合而制得的一种热塑性树脂。 [0002] polypropylene, a propylene prepared by the polymerization of a thermoplastic resin. 按甲基排列位置分为等规聚丙稀(isotactic polypropylene)、无规聚丙稀(atactic polypropylene)和间规聚丙稀(synd1tactic polypropylene)三种。 Methyl-arranged position into isotactic polypropylene (isotactic polypropylene), atactic polypropylene (atactic polypropylene) and syndiotactic polypropylene (synd1tactic polypropylene) three.

[0003] 甲基排列在分子主链的同一侧称等规聚丙烯,若甲基无秩序的排列在分子主链的两侧称无规聚丙烯,当甲基交替排列在分子主链的两侧称间规聚丙烯。 [0003] methyl and the like arranged on the same side of said syndiotactic polypropylene backbone of the molecule, if methyl orderly arranged on both sides of said atactic polypropylene molecular main chain, methyl alternately arranged in two molecular main chain said side syndiotactic polypropylene. 一般工业生产的聚丙烯树脂中,等规结构含量约为95%,其余为无规或间规聚丙烯。 Industrial production of polypropylene resin, the isotactic structure content of about 95%, the remainder being atactic or syndiotactic polypropylene. 工业产品以等规物为主要成分。 Industrial products and other regulations as the main ingredient. 聚丙烯也包括丙烯与少量乙烯的共聚物在内。 Also includes a polypropylene copolymer of propylene and a small amount of ethylene into account. 通常为半透明无色固体,无臭无毒。 Typically translucent colorless solid, odorless and non-toxic. 由于结构规整而高度结晶化,故熔点可高达167°C。 Due to the highly regular structure is crystallized, so that the melting point up to 167 ° C. 耐热、耐腐蚀,制品可用蒸汽消毒是其突出优点。 Heat-resistant, corrosion-resistant, steam sterilization is available for the article and its advantage. 密度小,是最轻的通用塑料。 Low density, is the lightest general-purpose plastics. 缺点是耐低温冲击性差,较易老化,但可分别通过改性予以克服。 Disadvantage is the low temperature impact resistance, easier to aging, but can be overcome by modifying respectively.

[0004] 共聚物型的PP材料有较低的热变形温度(100°C)、低透明度、低光泽度、低刚性,但是有更强的抗冲击强度,PP的冲击强度随着乙烯含量的增加而增大。 [0004] Copolymer PP materials have a lower heat distortion temperature (100 ° C), low transparency, low gloss, low rigidity, but there is a stronger impact strength, the impact strength of PP with an ethylene content increases. PP的维卡软化温度为150°C。 PP Vicat softening temperature of 150 ° C. 由于结晶度较高,这种材料的表面刚度和抗划痕特性很好。 Due to the higher degree of crystallinity, good surface scratch resistance and stiffness characteristics of such material. PP不存在环境应力开裂问题。 PP environmental stress cracking problem does not exist.

[0005] PP的熔体质量流动速率(MFR)通常在1〜100。 [0005] PP has a melt mass flow rate (MFR) is generally 1~100. 低MFR的PP材料抗冲击特性较好但延展强度较低。 MFR PP material is preferably a low impact properties, but low strength extension. 对于相同MFR的材料,共聚型的抗冲强度比均聚型的要高。 MFR for the same material, the impact strength of the copolymer homo-type is higher than. 由于结晶,PP的收缩率相当高,一般为1.6〜2.0%。 Due to crystallization, PP contraction rate is very high, typically 1.6~2.0%.

[0006] 聚丙烯的结晶度高,结构规整,因而具有优良的力学性能。 [0006] The high crystallinity polypropylene, regular structure, which has excellent mechanical properties. 聚丙烯力学性能的绝对值高于聚乙烯,但在塑料材料中仍属于偏低的品种,其拉伸强度仅可达到30MPa或稍高的水平。 The absolute value of the mechanical properties of polypropylene than polyethylene, the plastic material is still in the low varieties, which can reach a tensile strength of 30MPa or only slightly higher level. 等规指数较大的聚丙烯具有较高的拉伸强度,但随等规指数的提高,材料的冲击强度有所下降,但下降至某一数值后不再变化。 Like polypropylene having an isotactic index greater high tensile strength, but with the increase of isotactic index, impact strength decreased, but dropped to a certain value no longer changes.

[0007] 温度和加载速率对聚丙烯的韧性影响很大。 [0007] Effects of temperature and strain rate of the polypropylene great toughness. 当温度高于玻璃化温度时,冲击破坏呈韧性断裂,低于玻璃化温度呈脆性断裂,且冲击强度值大幅度下降。 When the temperature is higher than the glass transition temperature, fracture toughness, impact damage was below the glass transition temperature of brittle fracture and the impact strength dropped significantly. 提高加载速率,可使韧性断裂向脆性断裂转变的温度上升。 Loading rate increase, fracture toughness can increase to brittle fracture transition temperature. 聚丙烯具有优异的抗弯曲疲劳性,其制品在常温下可弯折106次而不损坏。 Polypropylene has excellent bending fatigue resistance, which at room temperature can be folded article 106 times without damage.

[0008] 但在室温和低温下,由于本身的分子结构规整度高,所以抗冲击强度较差。 [0008] However, at room temperature and low temperatures, because of their molecular structure regularity is high, the impact strength is poor. 聚丙烯最突出的性能就是抗弯曲疲劳性,俗称百折胶。 The most outstanding performance is the bending fatigue resistance of polypropylene, commonly known pleated plastic. 因此,可以采用聚丙烯材料制作密封条使用。 Thus, a polypropylene material may be employed using the seal.

[0009] 但是,现有的聚丙烯密封条通常为单一的条状结构,针对比较大型的聚丙烯密封条而言,在使用过程中容易损坏。 [0009] However, the conventional polypropylene as a single seal generally stripe structure, for comparison purposes the polypropylene seal large, easily damaged during use. 发明内容 SUMMARY
