preparation example Construction

[0036] The present invention provides a method for preparing the hydrophobic self-cleaning resin slurry described in the above technical solution, comprising the following steps:

[0037] Dimethacrylate monomer, triethylene glycol dimethacrylate, perfluoroalkyl acrylate, diluent, nano-silica, γ-methacryloxypropyltrimethoxysilane, camphor The quinone and the photocuring accelerator are mixed to obtain a hydrophobic self-cleaning resin paste.

[0038] In the present invention, the mixing is preferably carried out under light-shielding conditions, and in an embodiment of the present invention, the mixing is preferably carried out in a brown bottle. In the present invention, the mixing time is preferably 1.5 to 6 hours, more preferably 3 to 4.5 hours; the mixing temperature is preferably room temperature; the mixing method is preferably stirring and mixing. It is not particularly limited, as long as the preparation raw materials can be mixed uniformly.

[0039] In the present in...

Embodiment 1

[0045] (1) Mix 0.5g bisphenol A-glycidyl dimethacrylate (Bis-GMA), 1.5g triethylene glycol dimethacrylate (TEGDMA), 1.0g perfluoroalkyl acrylate (FMA) and 0.5 g of absolute ethanol was added into a brown glass bottle, and magnetically stirred for 0.5 h at room temperature to obtain the first mixture;

[0046] (2) Add 0.1g nano silicon dioxide (SiO 2 , with a particle size of 15-20nm) into the brown glass bottle, and at the same time, dropwise add 0.1g of γ-methacryloyloxypropyltrimethoxysilane (KH570) under magnetic stirring conditions, Magnetically stirred for 0.5h to obtain the second mixture;

[0047] (3) 0.0105g camphorquinone (CQ) and 0.02405g ethyl 4-dimethylaminobenzoate (EDMAB) were added into the brown glass bottle, and magnetically stirred for 1h at room temperature to obtain a hydrophobic self-cleaning resin slurry material;

Abstract

The invention provides hydrophobic self-cleaning resin slurry, a hydrophobic self-cleaning resin dental material and application of the resin slurry and resin dental material, and relates to the technical field of oral materials. The hydrophobic self-cleaning resin slurry provided by the invention is prepared from the following raw materials: a dimethacrylate monomer, triethylene glycol dimethacrylate, perfluoroalkyl acrylate, a diluent, nano silicon dioxide, gamma-methacryloyloxypropyltrimethoxysilane, camphorquinone and a light curing accelerator. The perfluoroalkyl acrylate is added, so that the surface energy of the material is reduced. By introducing nano silicon dioxide, the mechanical property of the resin is improved, the microscopic roughness of the resin is increased, a lotus-leaf-like hydrophobic micro-nano hierarchical structure is constructed, the hydrophobic surface of the micro-nano structure can retain air, an air layer is formed on the surface of the material, and the contact area with protein and bacteria is reduced. Therefore, the adhesion of related bacteria in the oral cavity and the formation of bacterial biofilms are inhibited, and the material has excellent self-cleaning biological decontamination performance.

Description

technical field [0001] The invention relates to the technical field of oral materials, in particular to a hydrophobic self-cleaning resin slurry, a hydrophobic self-cleaning resin dental material and applications thereof. Background technique [0002] The prevention of dental caries is a major public health need in China, and it is also considered to be the most important public health problem in the world and one of the serious burdens of disease treatment resources in the world. Maximizing the effect of caries prevention and treatment has become an urgent problem to be solved in clinical dentistry. The root cause of dental caries is the colonization of dental plaque biofilm on the surface of teeth by caries-causing bacteria as the dominant flora, decomposing carbohydrates in food, producing acid, and continuing to cause demineralization of tooth hard tissues. [0003] Common oral diseases such as dental caries, periodontitis, and local irritation factors of dental calculu...
