Description
Technical field
The invention belongs to technical field of polymer materials, relate to a kind of automotive upholstery microporous foam polypropylene composite materials material
Material and preparation method thereof.
Background technology
Plastic foam material has light weight, heat insulation, sound insulation, insulation, anticorrosion and an advantage such as cheap, thus packaging,
The fields such as building, agricultural, electronic apparatus and transportation have a wide range of applications.Wherein, main foams plastic material has poly-
Urethane (PU) expanded material, polystyrene (PS) expanded material and polyethylene (PE) expanded material three major types.But, this three class is sent out
Foam material has prominent shortcoming.Harmful isocyanates residue is there is in polyurethane (PU) in foaming process, and
Expanded material cannot recycle；Polystyrene (PS) generally uses environmentally hazardous HCFC or fourth in foaming
" white pollution " being difficult to degraded is easily formed after alkane, and use；Polyethylene (PE) expanded material rigidity and heat resistance are all
Poor.Under this background, polypropylene (PP) expanded material is paid close attention to the most widely by research worker.
Polypropylene (PP) expanded material has all advantages of plastic foam material, also has three big expanded materials simultaneously and does not has
Some advantages.The rigidity of this kind of expanded material is better than polyethylene (PE) expanded material, and has higher heat distortion temperature,
Operation at high temperature can reach 130 DEG C, significantly larger than 80 DEG C of polyethylene (PE) expanded material, it is often more important that, polypropylene (PP)
The easy recycling of expanded material, degradable, product is without to human body and the material of bad environmental.Based on above advantage, poly-third
Alkene (PP) expanded material has the most wide application prospect, especially at the automotive field of " light weight, energy-conserving and environment-protective ".But, poly-
Propylene belongs to linear crystalline polymer, flows hardly below fusing point, and fusing point viscosity above drastically declines, and is therefore difficult to support
The growth of bubble, be easily caused abscess subside, the generation of fracture phenomena, additionally, polypropylene specific heat capacity is relatively big, this makes it from melted
Can release substantial amounts of heat when state is transformed into crystalline state, can reduce the viscosity of melt further, these are all unfavorable for excellent abscess
The formation of structure, more can affect the mechanical property of foaming product.
