Description

A kind of automotive upholstery high heat resistance fiber reinforcement ASA/PC plastics and preparation method thereof

Technical field

The invention belongs to chemical material technical field, be specifically related to a kind of modified ASA/PC plastics and system thereof Preparation Method, particularly relates to a kind of automotive upholstery high heat resistance fiber reinforcement ASA/PC plastics and preparation thereof Method.

Background technology

Acrylicstyrene-acrylonitrile, English name: AcrylonitrileStyreneAcrylatecopolymer, It is abbreviated as ASA resin, is by acrylonitrile (acrylonitrile), styrene (Styrene), acrylate (Acrylate) ternary graft copolymer formed, it is with polyacrylate as main chain, with acrylonitrile, The non-crystalline type polymer of styrene monomer graft copolymerization.ASA resin early than 1962 by Germany BASF AG's industrialized production, subsequently FDAC chemical conversion also achieve industrialized production, at present, ASA resin is one of major product of GE company of the U.S..

ASA is a kind of opaque Yellow amorphous polymer, and nontoxic odorless, anti-flammability own reaches UL94HB level, hot strength is 38-48MPa, and under 1.83MPa load, heat distortion temperature is 85-105 DEG C, can use at-20～75 DEG C for a long time, there is preferable environmental stress crack resistance, simultaneously oil resistant, resistance to Hydrochloric acid solution, the bronsted lowry acids and bases bronsted lowry of resistance to alkene, but it is weak to esters, ketone, aromatics, chloro class and alcohols.

ASA resin is compared with ABS resin, and it does not contains double bond, therefore can support ultraviolet radiation resisting Under the degraded, aging and fade that causes, simultaneously work in-process can the effect of heat-resisting oxygen, prevent from decomposing and becoming Look.Therefore one of kind that during ASA plastic becomes plastics, weatherability is best, its ageing resistace compares ABS Plastics are high more than 10 times.The many advantages having due to ASA, the most progressively at industrial circle by extensively Application.Variously-shaped automotive upholstery can be easily processed into by Shooting Technique, such as hand at automotive field Casing inner cover plate, gloves hopper, instrument board, panel parcel tray etc..

Major part automobile component all with injection molding forming method process, the advantage of ASA resin be impact resilience, Sound-proofing, scratch-resistant are more preferable, more more attractive than PP, are particularly well-suited to horizontal impact resilience and use temperature relatively For strict parts.ASA resin can be used for Che Nei and car outer enclosure, steering wheel, oil guide pipe and handle With widgets such as buttons, outside car, include front radiator grille and lampshade etc..ASA resin is easily worked, Processing dimension stability and lustrous surface are good, easy application, coloring, it is also possible to carry out spray metal, electricity Plating, welding and the suitability for secondary processing such as bonding, can be widely applied to field of electronics, do including various Public affairs and consumer electronics/electrical equipment, office electrical equipment includes electronic data processing machine, office equipment.

PC refers to Merlon, is the high molecular polymer containing carbonate group in strand, according to ester group Structure can be divided into the polytypes such as aliphatic, aromatic series, aliphatic-aromatic.Wherein due to aliphatic Relatively low with the mechanical performance of aliphatic-aromatic Merlon, thus limit it in terms of engineering plastics Application.The industrialized production that only had at present what aromatic copolycarbonate obtained.Due on polycarbonate structure Particularity, has become the general engineering plastic that in five large-engineering plastics, growth rate is the fastest.

Heat endurance and the thermal shock resistance of ASA resin are not so good.These shortcomings seriously limit ASA The application of resin.

Thermal shock resistance, refers to that material, when bearing dramatic temperature change, evaluates the important finger of its resisting breakage ability Mark.Material behavior is its major influence factors, such as the thermal coefficient of expansion of material, thermal conductivity factor, springform Amount, material inherent strength, fracture toughness etc..In general, thermal coefficient of expansion is the least, and material is because of temperature The Volume Changes changed and cause is little, and the corresponding temperature stress produced is little, and thermal shock resistance is the best；Thermal conductivity Greatly, the temperature difference of material internal is the least, the temperature difference stress difference caused is the least, and thermal shock resistance is the best；Material Inherent strength is the highest, bears thermal stress and the intensity that will not destroy is the biggest, good thermal shock；Elastic modelling quantity The biggest, elasticity is the least, and material generation elastic deformation is less and can not alleviate and discharge thermal stress, to heat resistanceheat resistant Pinking is unfavorable.

The new crackle that material produces in thermal shock, and new crackle extend with original crack cause cracking, The situations, referred to as Thermal-shock Damage such as peeling, fracture.Thermal-shock Damage is the result of thermal stress effect.Material exists During temperature change, it is thermal stress that deformation is suppressed produced stress.Different heterogeneous of linear expansion coefficient Object is when temperature change, when the object of homogeneous thermal expansion is by thermograde effect, and during phase transformation, Thermal stress will be produced.Thermal stress is directly proportional to springform tribute and the elastic strain of material, and elastic strain Equal to linear expansion coefficient and the product of temperature change.The thermal shock resistance of ASA resin is unsatisfactory, needs Improving makes it be applied to more field.

Summary of the invention

For above-mentioned deficiency present in prior art, one of the technical problem to be solved provides A kind of automotive upholstery high heat resistance fiber reinforcement ASA/PC plastics, have good heat endurance and heat Shock resistance.
