A production process of waterproof coating

Abstract

This invention discloses a production process for waterproof coatings. The raw materials for the waterproof coating are fed into a mixing tank and mixed. The material output from the mixing tank is then passed through a colloid mill and reintroduced into the mixing tank, allowing for cyclic grinding. The material flow path for this cyclic grinding includes: material output from the top of the mixing tank cavity being passed through a colloid mill and then reintroduced into the bottom or vertical middle section of the mixing tank cavity; material output from the vertical middle section of the mixing tank cavity being passed through a colloid mill and then reintroduced into the bottom or top of the mixing tank cavity; and material output from the bottom of the mixing tank cavity being passed through a colloid mill and then reintroduced into the top or vertical middle section of the mixing tank cavity. This waterproof coating production process of the present invention enables cyclic grinding of the raw materials fed into the mixing tank. The cyclic grinding has multiple material flow paths, and two cycles can be alternated, allowing for thorough and efficient grinding of the material in the mixing tank, thereby improving the production efficiency and product quality of the waterproof coating.

Description

Technical Field

[0001] This invention relates to a production process for waterproof coatings. Background Technology

[0002] Waterproof coatings are solvent-based, water-emulsion, or powder-based coatings made primarily from synthetic polymers, polymers combined with asphalt, or polymers combined with cement, with various additives, modifiers, and fillers. When applied to surfaces requiring waterproofing, such as roofs, basements, bathrooms, and exterior walls, waterproof coatings form a continuous, integral waterproof layer of a certain thickness under normal temperature conditions.

[0003] The existing production process for waterproof coatings generally involves putting the raw materials of the waterproof coating into a mixing tank for mixing and stirring. During the mixing process, the material in the mixing tank is output through a colloid mill and then input back into the mixing tank, so that the material is circulated and ground.

[0004] However, the existing circulating grinding of waterproof coatings has a relatively simple material flow path. Generally, the material is only output from the bottom of the mixing tank cavity, passed through the colloid mill, and then input into the top of the mixing tank cavity. This single material flow path makes it difficult to achieve sufficient grinding of the material in the mixing tank, resulting in low grinding efficiency, which will affect the production efficiency and product quality of waterproof coatings. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a production process for waterproof coatings, comprising: feeding the raw materials of the waterproof coating into a mixing tank for mixing; and during the mixing process, outputting the material from the mixing tank through a colloid mill and then inputting it back into the mixing tank, so that the material is circulated and ground. The first material flow path is to output the material from the top of the mixing vessel cavity through the colloid mill and then input it into the bottom of the mixing vessel cavity. The material output from the top of the mixing vessel cavity passes through the colloid mill and is then input into the vertical middle of the mixing vessel cavity, forming the second material flow path; The material output from the vertical center of the mixing vessel cavity passes through the colloid mill and is then input into the bottom of the mixing vessel cavity, forming a third material flow path; The fourth material flow path is to output the material from the vertical middle of the mixing vessel cavity through the colloid mill and then input it into the top of the mixing vessel cavity. The material output from the bottom of the mixing vessel cavity passes through the colloid mill and is then input into the top of the mixing vessel cavity, forming the fifth material flow path; The material output from the bottom of the mixing vessel cavity passes through the colloid mill and is then input into the vertical middle of the mixing vessel cavity, which is the sixth material flow path; The first cycle consists of executing the first material flow path, the fourth material flow path, and the sixth material flow path in sequence. The second cycle consists of executing the fifth material flow path, the third material flow path, and the second material flow path in sequence. During cyclic grinding, the first and second cycles are performed alternately; and when any material flow path is executed (i.e., the first material flow path to the sixth material flow path), the material flow rate through the colloid mill reaches the predetermined flow rate.

[0006] For more details on cyclic grinding, please refer to the examples.

[0007] The advantages and beneficial effects of this invention are as follows: It provides a production process for waterproof coatings, which can perform cyclic grinding on the raw materials put into the mixing tank. The cyclic grinding has multiple material flow paths and can also be carried out alternately, which can fully and efficiently grind the materials in the mixing tank, thereby improving the production efficiency and product quality of waterproof coatings.
