Description
Technical field
The invention belongs to chemical material technical field, be specifically related to a kind of modified ABS plastics and preparation method thereof, particularly relate to a kind of automotive upholstery resistance to high thermal fiber reinforced ABS and preparation method thereof.
Background technology
ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the acronym of AcrylonitrileButadieneStyrene) is that a kind of intensity is high, good toughness, be easy to thermoplastics type's Polymer Materials ' Structure of machine-shaping.
ABS resin is the graft copolymer of vinyl cyanide, 1,3-butadiene and vinylbenzene three kinds of monomers.Its molecular formula can be written as (C

xbut in fact often containing the graft copolymer of divinyl and the mixture of acrylonitritrile-styrene resin, wherein, vinyl cyanide accounts for 15 ~ 35%, divinyl accounts for 5 ~ 30%, and vinylbenzene accounts for 40 ~ 60%, and the modal ratio of emulsion method ABS is A:B:S=22:17:61, and the ratio of B is often lower in substance law ABS, be about 13%.
ABS is the general thermoplastic engineering plastic grown up 1940's, it is the very outstanding plastics variety of a comprehensive mechanical property, not only there is good rigidity, hardness and processing fluidity, and there is high tenacity feature, can injection moulding, extrude or thermoforming.
Major part trolley part is all with injection molding forming method processing, and the advantage of ABS resin is that impact-resistance, sound-proofing, scratch-resistant are better, more attractive in appearance than PP, is specially adapted to horizontal impact-resistance and the comparatively strict parts of use temperature.ABS resin uses in automobile to be only second to Polyurethane and polyacrylic the third-largest resin.ABS resin can be used for Che Nei and car outer enclosure, and bearing circle, oil guide pipe and the widget such as handle and button, car outside comprises front radiator grill and lampshade etc.
ABS resin is easily processed, finish size stability and surface luster good, easy application, painted, metallize, plating, welding and the suitability for secondary processing such as bonding can also be carried out, field of electronics can be widely used in, comprise various office and consumer electronics/electrical equipment, office electrical equipment comprises electronic data processing machine, office equipment.
Thermostability and the thermal shock resistance of ABS resin are not so good.These shortcomings seriously limit the application of ABS resin.
Heat-shock resistance, refers to that material is when bearing dramatic temperature change, evaluates the important indicator of its resisting breakage ability.Material behavior is its major influence factors, as the thermal expansivity, thermal conductivity, Young's modulus, material inherent strength, fracture toughness property etc. of material.In general, thermal expansivity is less, and the volume change that material causes because of temperature variation is little, and the thermal stress of corresponding generation is little, and heat-shock resistance is better; Thermal conductivity is large, and the temperature difference of material internal is less, and the stress-difference caused by the temperature difference is less, and heat-shock resistance is better; Material inherent strength is higher, bears thermal stresses and the intensity of unlikely destruction is larger, good thermal shock; Young's modulus is larger, and elasticity is less, and material generation recoverable deformation is less and can not alleviate and rejected heat stress, unfavorable to heat-shock resistance.
The new crackle that material produces in thermal shock, and new crackle and original crack expand cause cracking, peel off, the situation such as fracture, be called Thermal-shock Damage.Thermal-shock Damage is the result of thermal stresses effect.Material is when temperature variation, and it is thermal stresses that distortion is suppressed produced stress.The different heterogeneous object of linear expansivity, when temperature variation, when the object of homogeneous thermal expansion is subject to thermograde effect, and during phase transformation, all can produce thermal stresses.Springform tribute and the recoverable strain of thermal stresses and material are directly proportional, and recoverable strain equals the product of linear expansivity and temperature variation.The thermal shock resistance of ABS resin is unsatisfactory, needs improvement to make it be applied to more field.
