Embodiment

[0220] 1 rigidity and elasticity

[0221] Table 1 lists some properties of polypropylene without ethylene comonomer and with various concentrations of ethylene comonomer: the considered polymers have comparable flowability values, and their main technical purpose It consists in carrying out the transformation by injection moulding.

[0222] All types of polypropylenes shown in Table 1 have insufficient impact resistance characteristics relative to polymer matrices modified with fillers and / or reinforcements with the aim of achieving high stiffness values.

[0223] The purpose of the present invention is to modify the polypropylene matrix to obtain an optimal balance of properties to produce products requiring both high rigidity and high impact resistance values.

Abstract

The invention relates to a process for the production of high-resiliency rigid composite material, a high-resiliency rigid composite material, and uses thereof.

Description

technical field [0001] The invention relates to a method for producing a highly elastically rigid composite material, a highly elastically rigid composite material and applications of the highly elastically rigid composite material. Background technique [0002] Compounding, known in the fields of petrochemical and plastics production, is a process for the production of composite materials that utilizes high friction values ​​(high mechanical shear) to allow thermoplastic polymers with various polyolefin properties to The molten state is mixed together. [0003] One of the limitations of polymerization methods in the background art is that these polymerization methods provide heterogeneous thermoplastic polymer materials that can have broad and balanced performance parameters that can meet the desired functional requirements of a particular article. [0004] These approaches make it difficult to simultaneously ensure rigidity and toughness in petrochemical process polymers ...
