Problems solved by technology

However, due to the relatively poor compatibility of PMMA and AS resin, an appropriate amount of compatibilizer needs to be added, and high-speed stirring is required to stir evenly, and the high-quality yield of the obtained product needs to be improved.

Embodiment 1

[0045] Super-tough PMMA resin, including complex polymerized acrylate rubber core and polymethyl methacrylate coated on the outside of the core, wherein the complex polymerized acrylate rubber core includes polymethyl methacrylate core and acrylate coated on the outside of the core It is a polymer formed by polymerizing monomers on the surface of the inner core. The mass fraction of the complex polymerized acrylate rubber core accounts for 20% of the combined weight of the complex polymerized acrylate rubber core and polymethyl methacrylate. The mass fraction of the acrylate monomer accounts for 65% of the combined weight of the acrylate monomer and the polymethyl methacrylate core.

[0046] The method for preparing complex polymerized acrylate rubber, the steps are as follows:

[0047] S1 First extract the polymerization inhibitor in the methyl methacrylate, heat the methyl methacrylate extracted from the polymerization inhibitor into a fluid state for 1-3 hours, the heating...

Embodiment 2

[0052] Super-tough PMMA resin, the difference between Example 2 and Example 1 is that the mass fraction of the acrylate monomer accounts for 50% of the total weight of the acrylate monomer and the polymethyl methacrylate inner core.

Embodiment 3

[0054] Super-tough PMMA resin, the difference between Example 3 and Example 1 is that the mass fraction of the acrylate monomer accounts for 60% of the total weight of the acrylate monomer and the polymethyl methacrylate inner core.

Abstract

This invention relates to the field of PMMA resins, particularly to a super-tough PMMA resin and a preparation method thereof. The technical scheme is characterized in that the super-tough PMMA resincomprises a composite polymerization acrylate rubber core and polymethyl methacrylate coated on the core, and the composite polymerization acrylate rubber core comprises a polymethyl methacrylate coreand a polymer coated on the core and formed by polymerizing an acrylate-based monomer on the core surface.

Description

technical field [0001] The invention relates to the field of PMMA resins, more specifically, it relates to super-tough PMMA resins and a preparation method thereof. Background technique [0002] Polymethyl methacrylate, polymers obtained by polymerization of acrylic acid and its esters are collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethyl methacrylate is the most widely used. The abbreviated code name of polymethyl methacrylate is PMMA, commonly known as plexiglass, which is by far the most excellent and relatively affordable variety of synthetic transparent materials. It is widely used in electronic appliances, medical equipment, automobiles, construction and other fields. However, the crack propagation energy of PMMA is low during the fracture process, showing obvious notch sensitivity and low notched impact toughness, so it needs to be toughened and modified. [0003] I...
