[0039] The preparation method of the fluorosilicon self-leveling antifouling material of the foregoing embodiment includes the following steps:
[0040] (1) Preparation of modified graphene oxide: add graphene oxide to deionized water, ultrasonically vibrate for 20 minutes, add acetic acid and molybdenum disulfide, stir evenly, wash with water, and filter; after the filter cake is dried at 45°C, add maleic acid Mix butyl tin and barium stearate, then add ethanol, reflux at 78°C and stir for 3 hours, concentrate under reduced pressure (rotate at 40-50°C until there are no droplets on the surface), and dry in a sterile oven at 50-80°C for 1-2 hours. Graphene oxide.
[0041] (2) Pre-dispersion: Put Portland cement, fly ash, quartz sand, nano-silica, calcium fluoride, diatomaceous earth, and ethylene-vinyl acetate latex powder into the dispersing machine in turn, stirring at 80-120r / min 40-60min to obtain pre-dispersed material.
[0042] (3) Total mixing: Put the pre-dispersed material...

The invention relates to the technical field of building materials and in particular relates to a fluorosilicon self-leveling antifouling material and a preparation method thereof. The fluorosilicon self-leveling material contains the following raw materials in parts by weight: 80-120 parts of Portland cement, 40-65 parts of fly ash, 10-30 parts of quartz sand, 5-20 parts of nano-silica, 3-15 parts of calcium fluoride, 4-12 parts of modified graphene oxide, 3-10 parts of graphene fibers, 1-6 parts of fluoroalkyl silane, 1-3 parts of diatomite, 0.5-3 parts of a silane coupling agent composition, 0.1-2.5 parts of vinyl-vinyl acetate latex powder, 0.1-0.6 part of a water reducing agent and 0.06-0.25 part of an antifoaming agent. The preparation method of the self-leveling antifouling materialcomprises the following steps: preparation of the modified graphene oxide, pre-dispersing and total blending. According to the fluorosilicon self-leveling antifouling material disclosed by the invention, the corrosion resistance, fouling resistance and stain resistance are improved on the basis of ensuring excellent liquidity, adhesion force and wear resistance of the self-leveling material.
Description
Technical field [0001] The invention relates to the technical field of building materials, in particular to a fluorosilicon self-leveling antifouling material and a preparation method thereof. Background technique [0002] Self-leveling material is a new type of building material that uses inorganic or organic gelling materials as the matrix and is used for self-leveling the ground by adding various modifiers and additives. It is mainly divided into two categories: organic self-leveling and inorganic self-leveling . Organic self-leveling is represented by epoxy resin plus functional additives. Inorganic self-leveling is divided into cement-based and gypsum-based according to different base materials. [0003] Cement-based self-leveling material is based on cement as the base material of the cementing material, usually Portland cement as the matrix, adding anti-cracking fiber, metal oxide or natural mineral fiber as reinforcement, and then compounding with fillers and additives Co...
