since the beginning of the 20th century in the 70 s, plastic varieties are growing fast, every year there are dozens of varieties. But since the 1970 s, the development of new varieties of plastic speed slow down, a few years to have a new birth; But to the rapid growth of the existing plastic varieties of production has been decades of double-digit growth.
plastic refers to the general polymer resin modified by physical, chemical, or both, some methods to introduce certain additives, or change the resin molecular chain structure, or forming interpenetrating network structure, and form a new island structure of high polymer resin material.
modified plastics is a wide range, high technology content, to create a huge economic benefit of plastic industry. And plastic modification technology & ndash; Reinforced filling, blend and more in-depth almost all of the raw materials and the forming process of plastic products. From the raw material of resin production and from a variety of specifications and varieties of modified plastic masterbatch, in order to reduce the cost of plastic products, improve its functionality, without plastic modification technology.
the characteristics of the modified plastics
1. Enhancement: changed with the strength of the glass fiber to plastic.
2。 Filling: give common plastic filling some minerals, make the nature of the plastic.
3。 Toughening: to common plastic to join some toughening agent makes the plastic can be resilient, modified products: track pads.
4。 Add flame retardant flame retardant: ordinary plastic resin, can make plastic flame retardant characteristics, the general bromine flame retardants have a + antimony, P, N, and inorganic flame retardant systems.
5。 Hardy: generally refers to the plastic under the low temperature cold resistant ability, due to the low temperature brittleness, inherent plastic to make plastic brittle at low temperatures, so like the inside of the car plastic parts, general requirements to cold.
PP material due to its sources, small density, good mechanical balance, chemical corrosion resistance, easy processing and the price is low wait for an advantage, which is widely used. But general PP material shrinkage rate, poor stability in dimension, prone to buckling deformation; Low temperature brittle broken, low temperature toughness is poor; Poor light ageing, heat ageing resistance faults. Can't satisfy the bumper, instrument panel, solar or lunar halo, special requirements of the engine fan and other parts, so general PP material must be modified.
the blending modification of PP material is joined in PP material toughening agent, filling agent modifier modified PP materials. Add elastomer (in PP material Toughening agent) Can significantly improve the impact toughness of PP and low temperature resistance, this is the effect of toughening. But the addition of elastomer can bring material strength and thermal deformation temperature drop, to overcome this phenomenon, in toughening system filled with high heat resistance, high rigid inorganic filler, can significantly improve the material rigidity, heat resistance and dimensional stability. In PP matrix, toughening agent and filler ratio between coordination, can produce a series of different properties of the materials, meet the functions of the different parts. Compared with the unmodified PP material, modified materials performance greatly broaden and toughening materials, as well as manufacturing of ultra high toughness can make again toughening, filling and high rigidity, high toughness fill toughening materials and filler material of high rigidity, high heat resistance.
modified plastics industry is a typical technological progress and consumption upgrade benefit industry. Its downstream products is also more concentrated in the home appliance, automobile, electric tools and toys and other industries. Auto parts, office equipment and other requirements to the large volume of modified plastics, but relatively low profit margin, total annual capacity in hundreds of thousands of tons.
day by day strengthens along with the global environmental protection consciousness, people is higher and higher requirement for plastic products of flame retardant, halogen free, low smoke, low toxicity, environmentally friendly flame retardant has become people pursuit of the goal. Therefore the development environmental protection modified plastics is also currently the common goal of mankind.
