Abstract

The invention discloses a high-oxygen-permeability polyacrylate material as well as a preparation method and application thereof, and belongs to the technical field of high polymer materials. The high-oxygen-permeability polyacrylate material disclosed by the invention is prepared from the following raw material components in parts by mole: 1 to 30 parts of methacryloyl-T-structure siloxane; 10 to 30 parts of a fluorine-containing methacrylate monomer; 10 to 30 parts of methacryloyl (trimethylsiloxy) silane; 10 to 30 parts of a methacrylate monomer containing fluorine and silicon; 1 to 10 parts of hydrophilic monomers; 1 to 10 parts of hydrophobic monomers; 1 to 10 parts of an all-silicon cross-linking agent; 0.01 to 0.5 part of a free radical initiator; and 0.1 to 5 parts of an ultraviolet absorbent. According to the invention, the hydrophobic agent and the fluorine-silicon-containing methacrylate monomer are added while the oxygen permeability is improved by utilizing methacrylic polysiloxane with a T structure, so that the oxygen permeability, the spectrum transmittance and the mechanical property of the polyacrylate material are comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high oxygen permeability polyacrylate material and its preparation method and application. Background technique [0002] Rigid gas permeable contact lenses for orthokeratology (hereinafter referred to as orthokeratology lenses) are currently the most widely used means of controlling myopia, and the control effect and safety on the development of myopia have been widely affirmed and recognized by medical staff and patients. The orthokeratology lens is made of highly oxygen-permeable materials. After wearing it for 8-10 hours every night, the patient can obtain clear naked eye vision on the second day. Due to the advancement of materials and processing technology, orthokeratology has undergone significant progress in recent years. It has the characteristics of no need for surgery, no pain, significant effect, predictable, reversible, and adjustable. In recent years, th...
