聚是加聚反应而成的聚合物,一种有机物。系白色蜡状材料,外观透明而轻。化学式为(C3H6)x,密度为0.89~0.91g/cm3, 易燃,熔点165℃,在155℃左右软化,使用温度范围为-30~140℃ 。在80℃以下能耐酸、碱、盐液及多种的腐蚀,能在高温和氧化作用解
PP has excellent chemical stability and is inert to most acids, bases, salts and oxidants. For example, it is stable in concentrated phosphoric acid, hydrochloric acid, 40% sulfuric acid and their salts at 100 ℃. Only a few strong oxidants such as fuming sulfuric acid can change them. PP is a non-polar compound, which is very stable to polar solvents, such as alcohol, , aldehyde, ketone and most carboxylic acids, but it is easy to dissolve or swell in some non-polar organic solvents
Although PP has higher mechanical strength and modulus than recycled PE, the impact resistance, especially stress cracking resistance, and low temperature performance of recycled PP are poor, like the new PP resin. These properties are determined by the aggregation structure and macromolecular chain structure of PP, so it can be modified by polyethylene. When the blends of recycled PE (LDPE, HDPE) and PP are made, if there are more recycled PP materials, the alloy can be directly prepared. For example, if 10% - 25% HDPE is added into PP, the impact strength of the modified blend is increased by more than 8 times than that of PP at - 20 ℃, and the processing fluidity is increased, so it can be applied to the molding of large containers. In terms of structure, the addition of PE destroys the crystallization of PP, such as the fragmentation of macrospherulites, and also reduces the crystallinity of PP; if EPDM is added into the system, the crystallization of PP is also reduced. About 5% can improve the compatibility of PP and PE, and the impact strength can also be improved by adding a small amount of EPR rubber.
There are tertiary carbon atoms in PP molecules, which are easily broken and degraded under the action of light and heat. PP without stabilizer will become brittle when heated at 150 ℃ for more than half an hour or exed to sunlight for 12 days. PP powder without stabilizer will degrade seriously and emit obvious acid taste when stored indoors for 4 months. Adding more than 0.2% antioxidant before PP powder granulation can effectively prevent degradation and aging of PP during processing and use. Antioxidants can be divided into two categories: free radical chain reaction Terminator (also known as the main antioxidant) and peroxide decomition agent (also known as auxiliary antioxidant). The reasonable combination of the main and auxiliary antioxidants will play a good synergistic effect. If PP is cooled slowly in the air after leaving the die, it will produce larger grains and the transparency of the product is low
