Problems solved by technology

However, the polarity difference between the inorganic antibacterial agent powder and polymethyl methacrylate is large, the compatibility is poor, and phase separation is easy to occur, these factors cause the inorganic antibacterial agent powder in the polymethyl methacrylate matrix Uneven distribution and easy precipitation will affect the appearance of the product and eventually cause the optical, thermal and mechanical properties of the product to decline, seriously affecting the quality of the product
In addition, these patents also have the disadvantages of complicated preparation process, high cost and unstable antibacterial effect.
There are no mature and stable antibacterial acrylic materials and products on the market so far. Therefore, research on an antibacterial acrylic material with good compatibility and excellent performance has a good application prospect and can bring good economic benefits.

Abstract

The invention relates to the technical field of polymer modification, in particular to an antibacterial acrylic material and a preparation method thereof. Inorganic antibacterial agent powder is subjected to surface modification to obtain modified inorganic antibacterial agent powder, and then the modified inorganic antibacterial agent powder, methyl methacrylate and a medium-temperature initiatorare mixed and ground in proportion to obtain nano oily antibacterial slurry. In the grinding process, the particle size of the modified inorganic antibacterial agent powder is reduced, and the dispersing performance of the modified inorganic antibacterial agent powder in the system is improved; meanwhile, methyl methacrylate is pre-polymerized under the action of the medium-temperature initiatorand is tightly combined with the modified inorganic antibacterial agent powder. In this way, the compatibility of the antibacterial acrylic material can be remarkably improved, the basic performance and the antibacterial performance of the antibacterial acrylic material are improved, and the antibacterial acrylic material can be stably used for a long time. The preparation method is simple in process and controllable in cost, and the prepared antibacterial acrylic material is excellent in performance and stable in quality, so that the antibacterial acrylic material has a good economic value.

Description

technical field [0001] The application relates to the technical field of polymer modification, in particular to an antibacterial acrylic material and a preparation method thereof. Background technique [0002] Acrylic material is polymerized from methyl methacrylate monomer. The chemical name is polymethyl methacrylate (PMMA). Because of its good light transmittance, it is also called organic glass. Acrylic sheet has the characteristics of light transmittance, not easy to crack, good toughness, easy to clean, and soft texture. It is mainly used in living scenes such as lighting bodies, roofs, roofs, stairs, and indoor wall panels. At the same time, with the construction of commercial housing and the popularization of consumers' awareness of environmental protection, the market's demand for new environmentally friendly, healthy, non-toxic, and non-radiation building materials is rapidly increasing; because acrylic materials have good chemical stability, easy dyeing, and easy ...
