modified engineering plastics injection molding process was developed rapidly, not only depends on the progress and application of modified engineering plastics technology market demand, but also depends on the development of modified engineering plastics molding technology.
polymer blending modification originated in 1846, Hancock mix of natural rubber and gutta-percha, made raincoat, thus proposes two bananas mixed with the thought of improving the performance of products, has experienced 100 years of history. Polymer modified theory from the early simple qualitative description to quantitative description of the 1990 s, the modification made by the original glass fiber coated reinforced plastics to alloying, molecular compound and micro structure analysis, and the development of nanometer composite technology.
due to the development of twin-screw extruder, promoted the development of the domestic modified engineering plastics industry, short 10 years, engaged in modified engineering plastics industry more than 200 enterprises, the total output of about 200000 tons.
50-20th century In the 70 s in the field of polymer micro cracks appeared successively theory, multiple theory, theory of shear yield and silver lines. The basic idea of these theories is silver grain production consume large amounts of energy, rubber particles and the existence of the shear zone is prevented and terminate the development of the silver grain, increase the toughness of the material.
compatibility of polymer blend theory is developed on the basis of statistical thermodynamics. Many scholars at home and abroad on the compatibility of polymer blend system a lot of research, there are many methods of determination of blending compatibility body are put forward.
in the process of the development of the blending modification of polymers, 80 - in the 20th century In the 90 s is the golden age in the development of high polymer material modification. During this period, as the automotive, electronics, communications and other related industries development, increasing the application of modified engineering plastics, expanding application fields, the growing market demand, promote the development of engineering plastics modification technology.
in the 1980 s, the world each big company focus particularly on polymer alloy compatibility, developed different compatilizer of alloy system, realized the practical application of blending polymer alloy. Various polymers, graft polymer, the advent of effective solution for the compatibility of different polymer blending system, promote the development of polyolefin-g-mah /.
liquid crystal modification technology is a new technology developed in the 1980 s. The presence of the liquid crystal polymer and its unique performance for theory and practice of polymer modified added new content. Liquid crystal polymer divided into two major categories of lyotropic and cause, has excellent physical, chemical and mechanical properties, such as high temperature high strength, high modulus of elasticity, thermal deformation temperature, small linear expansion coefficient, excellent flame retardancy, etc.
in the 1980 s, started to develop the dynamic vulcanization technology, used in the manufacture of thermoplastic elastomer. The so-called dynamic vulcanization is elastic and thermoplastic resin to melt blending, in the twin screw extruder melt blending, elastomer was & other; On-site vulcanization & throughout; 。 In fact, is in the process of sulfide crosslinking process, it is through the elastomer in screw high-speed shear stress and crosslinking agent occur under the action of a certain degree of crosslinking, and dispersed in carrier resin.
from the processing and molding equipment, injection molding machine, extrusion molding technology of manufacturing of the unit, the development of nearly 10 years. In addition of gas-assisted injection molding technology, play an important role in improve the quality of products, the same parts of multilayer injection molding technology to achieve the use different material, to satisfy the different requirements for engineering plastics equipment parts.
