Description

A kind of polyphenylene sulfide enhancing composite and preparation method thereof
Technical field
The present invention relates to polyphenyl thioether composite material field, and in particular to a kind of polyphenylene sulfide strengthens composite and its system Preparation Method.
Background technology
Polyphenylene sulfide English is abbreviated as PPS, is a kind of novel high-performance thermoplastic resin, with high mechanical strength, resistance to height Temperature, chemical proofing, fire retardant, heat endurance are good, excellent electrical properties the advantages of；But because polyphenylene sulfide crystallinity is high, cause There is the low defect of poor toughness, impact strength in polyphenyl thioether material, therefore, do not use pure polyphenylene sulfide material when in use Material, polyphenyl thioether material needs just be applied after carrying out the composite modified treatment of enhancing such as toughness reinforcing, increase impact strength.It is existing The fiber-reinforced modified main use glass fiber material and carbon fibre material of modern poly-p-phenylene sulfide ether material are modified treatment, change Property effect is significant, but glass fibre and carbon fiber production cost is high, environmental pollution big seriously limits composite polyphenylene sulfide material Application.
Basalt fibre is a kind of emerging novel inorganic environment-friendly and green high performance fibre material, is following China's emphasis One of four big high-performance fibers of development, it is aoxidized by silica, aluminum oxide, calcium oxide, iron oxide and titanium dioxide etc. The basalt building stones of thing composition are prepared from after high-temperature fusion by spinning technique.Basalt continuous fiber is not only stablized Property is good, but also with various excellent properties such as electrical insulating property, anticorrosive, flame resistant, high temperature resistant, and, basalt fibre The discarded object that production technology is produced is few, and environmental pollution is small, directly can be transferred in ecological environment after product abandonment, without any danger Evil, thus be a kind of qualified green, environment-friendly materials.
Therefore, glass is substituted using nontoxic, pollution-free, wide material sources, excellent performance, the basalt fiber material stablized Glass fiber and carbon fiber poly-p-phenylene sulfide ether material are strengthened, and polyphenylene sulfide enhancing composite is polyphenylene sulfide obtained from The new direction of enhancing composite development.But because basalt fibre is inorganic material, and polyphenylene sulfide is the organic material of macromolecule Material, both compatibility extreme differences, and basalt fibre self structure and stable performance, fiber surface is smooth, surface-active site is few, Basalt fibre is caused to be more difficult to carry out chemical bonding and mechanical riveted, i.e. basalt with polyphenyl thioether material in modifying process Fiber is to be individually present in polyphenyl thioether material, poly-p-phenylene sulfide ether Material reinforcement effect on driving birds is not good, polyphenylene sulfide enhancing composite wood The poor-performing of material.
The content of the invention
It is an object of the invention to overcome polyphenylene sulfide to strengthen the defect of composite property difference, there is provided a kind of polyphenylene sulfide Enhancing composite and preparation method thereof；The inventive method is modified treatment by the basalt fibre containing barium phosphate, Finally it is coupled with polyphenylene sulfide in the presence of coupling agent, is combined, so as to obtains basalt fibre and polyphenyl thioether material The more preferable polyphenyl thioether composite material of compatibility, basalt fibre poly-p-phenylene sulfide ether humidification more preferably, makes the composite Can be more excellent, be conducive to polyphenyl thioether composite material in the popularization and application of every field.
