Description
Technical Field
[0001] The utility model belongs to the technical field of polyurea waterproof coating production, and specifically relates to a mixing and proportioning device for the production of polyurea waterproof coating. Background Art
[0002] Polyurea waterproof coating is a two-component, solvent-free, fast-curing green and environmentally friendly elastic waterproof material. According to the different film-forming reaction groups, it is divided into high-elastic spray polyurea waterproof coating and high-elastic spray polyurethane elastic waterproof coating.
[0003] Polymai waterproof coating is a thermosetting polymer coating usually composed of poly resin silicone modifier, filler, solvent and additives. Polymai resin: Polymai resin is the main component of polymai waterproof coating, and its mass accounts for 30% to 40% of the total formula mass; silicone modifier: silicone modifier is mainly used to enhance the water resistance and chemical resistance of poly resin, and its mass accounts for 5% to 10% of the total formula mass. 3. Filler: Filler is an important component of polymai waterproof coating, mainly used to adjust the density and viscosity of the coating. Common fillers include white carbon black, wollastonite, etc., and their mass accounts for 30% to 40% of the total formula mass; Solvent: Solvent is the solubilizer of polymai waterproof coating, and its mass accounts for 10% to 20% of the total formula mass; Additive: Additive is an auxiliary component in polymai waterproof coating. Common additives include plasticizer, curing agent, stabilizer, etc., and their mass accounts for 5% to 10% of the total formula mass.
[0004] Different manufacturers will adjust and optimize the proportion of ingredients according to specific circumstances. However, no matter how they are adjusted and optimized, polyurea waterproof coatings cannot be separated from the mixing of raw materials during production. The existing mixing and proportioning devices cannot quantitatively feed materials, and thus it is difficult to ensure the ratio between the raw materials, resulting in deviations in the efficacy of the polyurea waterproof coating. At the same time, during the mixing process, it is difficult to ensure uniform mixing of multiple raw materials, which has great limitations. For this reason, we provide a mixing and proportioning device for the production of polyurea waterproof coatings that can ensure the ratio of raw materials and uniform mixing. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model is provided with a material storage barrel, a fixed box, a proportioning box and a guide pipe. When directional feeding is performed, the movable plate is pulled to move by a telescopic rod close to one side of the material storage barrel, and the movable plate enters the fixed box through the through hole along the guide groove. At this time, the raw materials in the material storage barrel enter the proportioning box until the proportioning box is filled with raw materials. After that, the telescopic rod pushes the movable plate to reset, and the other telescopic rod pulls the movable plate to contract, so that the raw materials in the proportioning box enter the inner part of the shell through the guide pipe and the feed port, and quantitative feeding can be performed. Moreover, each proportioning box can be set to different sizes according to the proportion of the raw materials, thereby ensuring the ratio between the raw materials.

[0015] 2. The utility model is provided with a rotating table, a slide, a slide seat, a rotating motor, a rotating rod, a stirring rod and an electric push rod. When the raw material enters the shell and needs to be mixed and stirred with the liquid, the driving motor drives the rotating table to rotate through the connecting rod. At the same time, the rotating motor drives the rotating rod and the stirring rod to rotate. When the rotating table rotates, the stirring rod stirs the raw material and the solution, and the electric push rod in the slide seat pushes the slide seat to move back and forth along the slide direction, so that the stirring rod can stir different positions in the shell, thereby ensuring that the raw material is fully mixed and stirred in the shell, avoiding the formation of a vortex in the solution in the shell, causing the raw material to be deposited at the center position and unable to be fully mixed and stirred.
