Thermoplastic

Abstract

The invention discloses thermoplastic which consists of the following raw materials by mass: 70-90 parts of polypropylene, 5-20 parts of photocureable cross-linking monomer, 8-25 parts of oligomer, 2.5-5.5 parts of photoinitiator, and 0.5-1.5 parts of photosensitizer. The visible-light cross-linking monomer can be an acrylic acid ester monomer, the oligomer can be one or more of bisphenol A epoxy diacrylate and modified epoxy diacrylate, and the photoinitiator is 1-hydroxy-cyclohexyl-phenyl ketone. Blending of a comparatively small number of the photocureable cross-linking monomer, oligomer, photoinitiator, photosensitizer and a lot of the thermoplastic can reduce the viscosity of the mixed system, thus both improving moulding manufacturability of the thermoplastic and its composite materials, avoiding possible potential matrix decorrelation resulted from high temperature moulding, and reserving the excellent performance of the thermoplastic.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to thermoplastics. Background technique [0002] Thermoplastic polymers have many excellent properties such as high temperature resistance, strength, stiffness and toughness. However, due to the rigidity of its main chain structure, its melt viscosity is very high, making it difficult to form and process, and it may also degrade under high temperature forming conditions. This characteristic leads to many difficulties in extrusion molding, injection molding, rotational molding, powder coating and its composite molding. In recent years, there have been a small number of research reports on the influence of reactive plasticizers on the molding process and properties of thermoplastic composites, but these studies are mainly achieved through the gradual polymerization of relatively viscous oligomers, and the molding process is limited to injection molding.
