Waterproof coating stirring and mixing preparation system and preparation process

Abstract

The invention relates to the technical field of coating preparation, in particular to a waterproof coating stirring and mixing preparation system and process, feeding devices are fixedly mounted at the two ends of the upper surface of a base, air pressure devices are fixedly mounted at the tops of the feeding devices, and a rotating device is fixedly mounted in the center of the base; a stirring device is fixedly mounted at the top end of the rotating device, a stirring tank body is fixedly mounted at the position, located on the outer side of the rotating device, of the upper surface of the base, and layered material pouring pipes are fixedly mounted at the positions, located on the two sides of the rotating device, in the stirring tank body. According to the powder and liquid mixing device, powder and liquid can be repeatedly and dispersedly poured into the mixing tank according to the proportion, the powder and the liquid can be more sufficiently contacted, meanwhile, the feeding proportion of the powder and the powder liquid is more accurate, particles or solids formed due to insufficient contact of the powder and the powder liquid in the mixing tank can be cut, and the powder and the liquid can be uniformly mixed. The powder and the powder liquid are in full contact, the quality of the waterproof coating is improved, and the problem that the powder and the powder liquid flow in the conveying pipe can be solved.

Description

technical field [0001] The invention relates to the technical field of coating preparation, in particular to a stirring and mixing preparation system and a preparation process for waterproof coatings. Background technique [0002] Waterproof coating is a kind of film used on the surface of buildings, which forms a film by the volatilization of solvent or water or the chemical reaction of the two components, so that the surface of the building is isolated from water, thus playing the role of waterproofing and sealing. The viscous liquid brushed is called waterproof coating. The waterproof film formed after curing the waterproof coating has certain extensibility, elastoplasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof, anti-seepage and protection. The waterproof coating has good temperature adaptability, is easy to operate, and is easy to repair and maintain. [0003] At present, when preparing waterproof coatings, there ...

AI Technical Summary

Problems solved by technology

[0003] At present, when preparing waterproof coatings, there are the following problems: 1. The preparation of waterproof coatings is made by stirring powder and liquid materials according to a certain ratio. The powder materials are generally cement fine sand and some special active substances, and the liquid materials It is composed of some polymers and additives. First pour the powder into the mixing tank, and then add the liquid material for stirring. This method is compared to pouring the powder and liquid material into the mixing tank in proportion to multiple dispersions. There are obvious shortcomings, it is difficult to fully stir the powder and liquid materials, thus affecting the quality of waterproof coatings

[0004] 2. In the process of pouring the powder and powder liquid for the preparation of waterproof coating into the mixing tank for stirring, particles or solid substances may be formed due to insufficient contact between the two, which will affect the quality of the waterproof coating, and during the feeding During the mixing process, due to the poor fluidity and strong viscosity of some powder and liquid materials, some powder and liquid materials stick to the feeding pipe and stirring rod, resulting in waste of raw materials and even blockage of the pipe. At the same time, due to the waste of raw materials, the proportion of ingredients in the mixing process is not accurate enough, which affects the quality of the waterproof coating, and in the process of stirring, due to the small contact area between the rotating device and the liquid in the tank, it cannot be well in the rotating process. The medium drives the liquid in the tank to rotate to form a vortex, which makes it difficult to make the powder and the powder liquid fully contact and complete the stirring
