Description
Technical Field
The invention relates to a high-elasticity crosslinked polypropylene foam material and a preparation method thereof, belonging to the technical field of high polymer materials.
Background
The radiation cross-linked polyethylene foam plastic is a novel foam plastic with a closed cell structure between soft (polyurethane) foam plastic and hard (polystyrene) foam plastic, has a series of characteristics of excellent toughness, elasticity, flexibility, wear resistance, chemical corrosion resistance, low temperature resistance, good insulativity and the like, can be used as a good insulating, heat insulating, shockproof and buoyancy material, and is widely applied to various fields of industry, agriculture, buildings, transportation and the like. However, the PE foam plastic has poor mechanical properties, poor heat resistance (the maximum use temperature is only about 80 ℃), difficult degradation and the like, which limit the application of the PE foam material. Polypropylene (PP) foams have many excellent properties, including low cost, good temperature resistance, high melting point, high tensile modulus, low density, and good chemical resistance, and are "new" in the foaming industry. In terms of mechanical properties, PP has higher static bearing capacity than PE and higher impact toughness than PS. Polypropylene (PP) foams have attracted much attention because of their excellent heat resistance, mechanical properties, and environmental friendliness, and thus have become high-performance green foams as alternatives to PU, PE, and PS foams in advanced countries such as europe, america, and the sun.
Despite the superior properties, PP foaming is difficult and heavy, mainly because the molecular chains of ordinary PP are linear, and the biaxial stretching effect to which the cell walls are subjected during foaming causes the entanglement of the linear chains to be rapidly opened, and the molecular chains easily slide relatively, so that the stretching viscosity is low. Even if a small stress action is applied, the PP is greatly deformed, so that the PP is expressed as that the strength of a cell wall is low in the foaming process, the PP is easy to break, and meanwhile, a large amount of gas in the cell escapes and diffuses into the environment, and finally, the defects of the foamed product, such as cell wall thickness, non-uniform cell size, low foaming ratio and the like, are caused. Meanwhile, due to the high melting point of PP, the extrusion processing temperature is above 140 ℃, and the Ac foaming system of the traditional polyethylene can not be adopted in the high-temperature processing process.
