Description
Technical field
The present invention relates to a kind of light composite material, relate to more specifically tiny balloon and corpus fibrosum matrix material.
Background technology
Matrix material has been widely used in the fields such as aviation, building, automobile.Composite density is generally higher, although polymer matrix composites density is lower, generally also surpasses 1.5g/cm
3Existing composite inner mostly is solid construction, and it is unsatisfactory in aspect effects such as heat insulation, sound insulation, dampings.Fibre composite is as the type material of the development of in recent years advancing by leaps and bounds, and due to special physical properties and stable chemical property, especially outstanding light weight, high strength are widely used on engineering.
Fill in recent years the hollow glass micro-ball modified plastics, it is not rare that perhaps direct combination becomes the research report of matrix material.As luxuriant in seedling, Cheng Wenxi delivers " research of the filling-modified PVC of hollow glass micro-ball " (" Henan chemical industry " 15 phases in 2011), reported that the employing blending method has synthesized hollow glass micro-ball/polyvinyl chloride (PVC) matrix material, hollow glass micro-ball has first carried out surface modification with silane resin acceptor kh-550 before using.The content of having studied hollow glass micro-ball by means such as Powerful Light Microscope, infrared spectrum analyser, electronic tensile machine, shore hardness detectors is to PVC tensile strength, the performance impacts such as shock strength and hardness.Result shows: along with the increase gradually of glass microsphere content, the tensile strength of PVC matrix material first increases rear reduction, and elongation constantly reduces, and shock strength descends slightly, and hardness constantly increases.Miao Wei, Cheng Wenxi " research of hollow glass micro-ball modified phenolic resins " (" industrial plastic application " 12 phases in 2009) of also delivering have been studied the impact of hollow glass micro-ball on resol (PF), have confirmed the existence of hollow glass micro-ball by opticmicroscope and infrared spectra.When to add massfraction be 5% hollow glass micro-ball, hardness and the thermostability of PF all were improved, hollow glass micro-ball during less than or equal to 15 μ m higher than pure PF.The fixation hollow glass microsphere is 15 μ m, and the hardness of PF and thermostability slowly improve along with the increase of glass microsphere content is first rear rapidly; Shock strength first increases rear reduction with the increase of content, reaches maximum value when massfraction 5%.In various matrix material researchs, hollow glass micro-ball comes modified composite material as important technical.
Matrix material about hollow bead also early has report, as Chinese patent application number: 02110464.6 discloses a kind of matrix material that contains hollow bead and preparation method thereof, belong to the compositions field of using inorganic and organic batching, comprise base starting material and aggregate, it is characterized in that adopting coal gangue powder, industrial slags fine powder, cement or refractory cements, aluminum oxide fine powder, alumine powder, zircon corundum powder is base starting material, the matrix material of preparation take hollow bead as aggregate.A kind of preparation method adds coal gangue powder and/or industrial slags fine powder and/or cement in model, then adds the hollow bead of entry, whipping agent and different diameter, presses to the section bar with definite shape through mixing, vibrate, adding; Also can mix with aluminum oxide fine powder or with aluminum oxide hollow bead, water, make the high alumina ceramic matter section bar with definite shape through extrusion forming, oven dry, roasting.This matrix material is slightly high, and quality is light, and has the performances such as excellent heat insulation, sound insulation, insulation and directed infiltration, can be widely used in building, kiln and the field such as agriculture.
When nowadays constantly pursuing better heat insulation, sound insulation, damping texts in the research of matrix material, also in the attractive in appearance and weight of paying close attention to material.Fiber applications is in matrix material, just weight reduction preferably.As Chinese patent application number: 201110002811.1 disclose a kind of light wood plastic composite material and manufacture method thereof, and the formula of this matrix material and mass fraction thereof are: 30～100 parts of Expandable Polystyrene (EPS)s, 50～300 parts of xylons, 1～3 part of coupling agent, 4～30 parts of tackiness agent.Its manufacturing process then uses the silane coupling agent surface treatment then to mix with EPS to xylon for first xylon being dried to water ratio 2-5%, then carries out applying glue, assembly, precompressed, the last hot-forming light wood plastic composite material that obtains.The light wood plastic composite material that the present invention makes, have lower than common wood plastic composite density, production technique is simple, cost is low, physical and mechanical property is superior and process the characteristics such as easy to use, can be widely used as furniture material, wrapping material and materials for wall and use.
The inventor pursues better heat insulation, sound insulation, damping texts when research is alleviating matrix material weight.Creationary fiber and hollow glass micro-ball modified resin are obtained a kind of light composite material, and have better heat insulation, sound insulation, damping effect.
