Example three:
the antistatic non-ignition wear-resistant polyurea terrace coating comprises the following components in percentage by mass: 15-25% of amino resin, 8-10% of modified acrylic resin, 20-30% of polycaprolactone polyol, 10-16% of ammonium polyphosphate, 5-15% of pentaerythritol, 2-4% of melamine, 5-8% of aluminum hydroxide, 6-10% of N, N-dimethylformamide and 2-5% of kerosene; the anti-static non-ignition wear-resistant polyurea terrace coating comprises the following components in parts by weight: the flame-retardant coating comprises, by weight, 20 parts of amino resin, 10 parts of modified acrylic resin, 25 parts of polycaprolactone polyol, 14 parts of ammonium polyphosphate, 10 parts of pentaerythritol, 3 parts of melamine, 7 parts of aluminum hydroxide, 8 parts of N, N-dimethylformamide and 3 parts of kerosene, wherein the ratio of the amino resin to the modified acrylic resin is 2; the amino resin is not only base resin, but also foaming agent, the thickness of the coating carbonization layer is increased along with the increase of the using amount of the amino resin, if the amino resin is completely used, the coating carbonization layer is higher, but the carbonization layer is loose, has insufficient strength, is easy to be damaged by high-pressure flame, and has shorter flame-retardant time of the coating, so that the flame-retardant property of the coating can be ensured only by the thickness and the strength of the coating carbonization layer, when the ratio of the amino resin to the acrylic resin is 2: the coating with a small area begins to be carbonized and foamed, but the middle of the coating begins to bulge, and a large block of coating falls off when being heated, which is mainly caused by insufficient adhesive force between the coating and the bottom layer, although the coating is well connected with the bottom layer before being not burned, after the coating is heated and melted, the adhesive force between the melted resin and the bottom layer cannot bear the weight of the coating and the carbonized layer, and the phenomenon that the large block falls off when the coating is heated appears, and the expansion foaming effect is influenced to a certain extent along with the increase of the addition amount of the resin, but the adhesive force between the coating and the bottom layer when the coating is melted is increased, so that the falling off of the large block of the melted coating is prevented, and when the content of the resin is too high, the thickness and the flame retardant effect of the carbonized layer of the coating can be influenced, therefore, the optimal addition amount of the resin is 25%, and the preparation method comprises the following steps:
(1) Fully cleaning a stirrer container, pouring amino resin, modified acrylic resin, polycaprolactone polyol, ammonium polyphosphate, pentaerythritol and melamine into the container, starting the stirrer to stir to obtain a mixed solution A, wherein the stirrer is an industrial-grade stirrer, and the rotating speed of the stirrer in the step (1) is 1000r/min and the duration time is 10min;
(2) Taking out the mixed liquid A after stirring, pouring the mixed liquid A into a vibrator for vibration mixing after the container of the vibrator is fully cleaned, wherein the vibrator is an industrial-grade ultrasonic vibrator, the vibration frequency of the vibrator in the step (2) is 20k, and the duration is 10min;
(3) After the mixture is vibrated for a certain time, closing the equipment, sequentially adding aluminum hydroxide, N-dimethylformamide and kerosene into the vibrator, then starting the equipment again, and continuously vibrating to obtain a mixed solution B, wherein the vibration frequency of the vibrator in the step (3) is 20k, the vibration time is 20min, in the step (3), the adding proportion of the aluminum hydroxide is 7% of the total mass of the mixed solution B, the surface resistivity of the formed film of the mixed solution B is 107, hydroxyl groups of the aluminum hydroxide interact with moisture in the air through hydrogen bonds and the like, and a conductive layer is formed on the surface layer of the coating, so that the integral antistatic performance of the coating is improved, in the step (3), the reaction time of the aluminum hydroxide is 30min, the particle size of the aluminum hydroxide is about 0.3 micron, and when the reaction time of the aluminum hydroxide is 30min, the obtained particle size is only 0.3 micron, so that the dispersion of the aluminum hydroxide in the coating can be facilitated, and the integral performance of the coating is improved;
(4) Mixed liquor B after shaking was taken out, and the stirrer vessel and the shaker vessel were sufficiently cleaned for the next use.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
