Description
Technical field
The present invention relates to general thermoplastic composite of a kind of ceramic fiber modification and preparation method thereof.
Background technology
Ceramic fiber is a kind of fibrous light refractory materials that integrates conventional insulation material, refractory materials premium properties, has low heat conductivity, good thermostability, chemical stability, non-corrosiveness.The diameter of ceramic fiber is generally 2 μ m～5 μ m, and length mostly is 30mm～250mm, and it is slick cylindrical that fiber surface is, and cross section is normally circular.Its constructional feature is void content height (generally greater than 90%), and air vent aperture and specific surface area are big.Because the air in the pore has good heat-blocking action, thereby the size of air vent aperture and the character (ventilate or the hole of holding one's breath) of pore have decisive influence to its heat conductivility in the fiber.In fact, the internal organizational structure of ceramic fiber is a kind of mixed structure of being made up of solid-state fiber and air, its microstructure characteristics all are that form with external phase exists in solid phase and gas phase, therefore, in this structure, solid matter exists with filamentous form, and constitutes the external phase skeleton, gas phase then continued presence among the skeleton gap of filamentary material.Have this structure just because of ceramic fiber, make that its void content is higher, air vent aperture and specific surface area be bigger, thereby make ceramic fiber have good heat-proof quality and smaller volume density.Be used for industry insulation, sealing, protective material, electric heating device insulation, lagging material, the insulation of plant and instrument, electrical heating element and heat insulation material, automobile industry lagging material etc. more.
The liquid crystal polyester dipping ceramic fiber of printed circuit board (PCB) and the refinforced cement based composites that is used to build also appear being used in recent years.Do not see that ceramic fiber is used for the report of interchangeable heat thermoplastic plastic.
General-purpose plastics has five big kind, i.e. polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS.They all are thermoplasticss.
Polyethylene is the highest kind of output in the plastics industry.Polyethylene is a crystalline plastic opaque or translucent, light weight, has good resistance to low temperature (minimum use temperature can reach-70～-100 ℃), and electrical insulating property, chemical stability are good, the erosion of the most of soda acids of ability, but thermo-labile.The suitable methods such as injection moulding, blowing, extrusion molding that adopt of polyethylene are processed.
Polypropylene is the thermoplastics that is got by propylene polymerization, be generally colourless, translucent solid, odorless is nontoxic, and density is 0.90～0.919 grams per cubic centimter, is the lightest general-purpose plastics, its outstanding advantage is the characteristic with anti-boiling in water, corrosion-resistant, intensity, rigidity and the transparency are all good than polyethylene, and shortcoming is that low-temperature impact resistance is poor, easily aging, but can be improved by modification and interpolation auxiliary agent respectively.Polyacrylic production method has 3 kinds of slurry process, liquid phase noumenal method and vapor phase processs.
Polyvinyl chloride is the plastics that got by chloroethylene polymerization, and by adding softening agent, its hardness can change significantly.The boardy product that it is made all has been widely used down to soft goods.The production method of polyvinyl chloride has suspension polymerization, emulsion polymerization and mass polymerization, based on suspension polymerization.
General polystyrene is cinnamic polymkeric substance, appearance transparent, but the shortcoming of embrittlement is arranged, therefore, can be made into impact resistant polystyrene (HTPS) by adding polyhutadiene.The main production method of polystyrene has mass polymerization, suspension polymerization and solution polymerization.
ABS resin is three kinds of common polymerized product of monomer of acrylonitrile-butadiene-styrene (ABS), is called for short the ABS terpolymer.This plastics are because its component A (vinyl cyanide), B (divinyl) are different with S (vinylbenzene) ratio in composition, and the difference of manufacture method, and its character also has very big difference.ABS is fit to injection moulding and extrusion processing, so its purposes also mainly is to produce this two based article.
General general-purpose plastics all faces the modification of specific functionization such as heat-resisting, heat insulation, fire-retardant, so that be applied to the Industrial products field, but in existing study on the modification such as heat-resisting, fire-retardant, do not appear in the newspapers and introduce suitable ceramic fiber, improve heat-resisting, the flame retardant properties and the balance physical and mechanical property of interchangeable heat thermoplastic plastic as function modified component.
