Description

Technical Field

[0001] This utility model belongs to the field of putty technology, and relates to a putty production system, and more particularly to a production system for modified epoxy water-based putty. Background Technology

[0002] Epoxy resins are widely used in industrial anti-corrosion, bonding, and flooring applications due to their excellent properties such as high adhesion, high mechanical strength, strong chemical corrosion resistance, and high insulation. However, because epoxy resins are generally insoluble in water, traditional epoxy resins often require the addition of large amounts of solvents to reduce viscosity for ease of application. This results in the release of volatile organic compounds (VOCs) into the environment during production and use, causing pollution and posing a threat to human health. For solvent-based epoxy putty composed of epoxy resins, the organic solvents contained in these puttyes are typically highly destructive and volatile, such as damaging the exterior wall insulation layer and shortening the lifespan of buildings. Furthermore, the volatilized gases often contain many environmentally harmful substances (such as styrene), which can cause pungent odors, eye irritation, throat and skin irritation, especially at construction sites during hot seasons, seriously affecting the health of workers. Therefore, the market urgently needs a high-performance, environmentally friendly putty product that does not contain traditional reactive diluents such as styrene.

[0003] Currently, to meet environmental protection requirements, the water-based nature of putty has become an inevitable trend. Therefore, the development of environmentally friendly water-based putty has become a trend. However, the production system for compatible modified epoxy water-based putty is almost non-existent, resulting in the limited small-scale production of modified epoxy water-based putty, which cannot achieve industrialized and large-scale production.

[0004] Therefore, a system is needed to support the production of modified epoxy water-based putty in order to achieve the industrial production of modified epoxy water-based putty. Summary of the Invention

[0005] To address the near-absence of existing production systems for modified epoxy water-based putty, which fails to guarantee the performance and stability of the product and hinders industrial-scale production, a new production system for modified epoxy water-based putty is proposed. This technical solution utilizes specific settings and arrangements of equipment in the main component preparation unit and the curing agent component preparation unit to achieve the preparation of the two-component putty product. This ensures, on the one hand, the stability of the performance of each component to meet practical requirements (e.g., thixotropic index > 3.5, pencil hardness ≥ H); and on the other hand, it guarantees the batch-to-batch quality stability of the two-component modified epoxy water-based putty, thereby enabling industrial-scale production.

[0006] To achieve the above technical objectives, the following technical solution is proposed:

[0054] Example 6

[0055] Based on Examples 1-5, this example provides: a method for preparing modified epoxy water-based putty, comprising the following steps:

[0056] S1: Preparation of the main component

[0057] The base epoxy resin and hyperbranched polyester modified epoxy resin were added to mixing vessel I101 and mixed evenly. Then, the dispersant was added and stirred until evenly mixed. While stirring, the rheology modifier (anti-settling agent) and defoamer were added in sequence and stirred until evenly mixed (about 5-10 minutes; to establish an effective anti-settling system). Finally, titanium dioxide was added and mixed evenly under high-speed dispersion at 1000-1200 r / min to obtain a coarse suspension without obvious particles.

[0058] The obtained coarse suspension was fed into a sand mill and ground to a fineness ≤20µm to obtain titanium dioxide slurry. The titanium dioxide slurry was then dispersed at a high speed of 1000-1200 r / min, with the addition of talc, silica fume, precipitated barium sulfate, and aqueous colorant, until the fineness was ≤100µm. The speed was then reduced to 600-800 r / min. While stirring, functional nanomaterials, aqueous cosolvent, anti-flash rust agent, and wetting agent were added sequentially, and the mixture was stirred until a uniform paste was formed (approximately 20 min). This paste was then ground using a three-roll mill to a fineness ≤50µm, with the following control: the proportion of particles <30µm was 5-10%, the proportion of particles 30-35µm was 60-70%, and the proportion of particles 35-50µm was 20-30%, thus obtaining the main component. The consistency of the main component was adjusted to 13-15 with purified water.

[0059] S2: Preparation of curing agent components

[0060] Add the modified fatty amine (modified curing agent) to mixing vessel II103, add the dispersant while stirring, and stir until homogeneous; while stirring, add the rheology modifier (anti-settling agent) and defoamer in sequence, stirring until homogeneous (about 5-10 min; to establish an effective anti-settling system); under high-speed dispersion at 1000-1200 r / min, add talc powder and silica powder, and disperse until the fineness is ≤100µm; reduce the speed to 600-800 r / min, stirring continuously. Add water-based co-solvent, anti-flash rust agent, wetting agent, and purified water (approximately 60% of the total volume) while mixing until a uniform paste is formed. Grind the paste using a three-roll mill until the fineness is ≤50µm, controlling the following: 5-10% of the particles with a fineness <30µm, 70-80% of the particles with a fineness of 30-35µm, and 15-20% of the particles with a fineness of 35-50µm. This yields the curing agent component. Test the consistency of the curing agent component and adjust it to 12-14 with purified water.

[0061] When using, mix the main component and the curing agent component by weight ratio (e.g., 2:1) and stir evenly to obtain modified epoxy water-based putty.

[0063] Based on Example 6, this example provides: a modified epoxy water-based putty, comprising a main component and a curing agent component, wherein the weight ratio of the main component to the curing agent component is 2:1;

[0064] The main components, by weight percentage, include: 16% CYD-128 resin (Yueyang Baling Petrochemical, base epoxy resin), 2% hyperbranched polyester modified epoxy resin, 1% DISPERBYK-2012 dispersant, 2% AEROSIL R972 rheology modifier, 1% BYK-022 defoamer, 3% titanium dioxide, 28% talc, 28% silica fume, 3% precipitated barium sulfate, 1% water-based color paste, 1% functional nanomaterials, 0.7% BYK-348 wetting agent, 3% propylene glycol methyl ether acetate PMA water-based cosolvent, 9% purified water, and 1.3% Halox Flash-x-150 water-based flash rust inhibitor.

[0066] The product specifications of this modified epoxy water-based putty include: surface drying time ≤ 2h (25℃), anti-sagging thickness ≥ 5mm, pencil hardness ≥ H, adhesion (cross-cut test) grade 0, thixotropic index > 3.5; sanding properties: easy to sand, easy to generate dust, does not stick to sandpaper.

[0068] Drying property: Mix the main component A and the curing agent component B evenly, dry thoroughly at room temperature (15-30℃) for 24 hours, and test according to GB1728-79 standard;

[0075] This modified epoxy water-based putty can be specifically used for painting rail transit vehicles.

[0076] Discussion Example

[0077] Based on Examples 1-7, this discussion example is as follows: In the production system of modified epoxy water-based putty, the preparation of the main component and / or curing agent component is not carried out by grinding with a three-roll mill, but the uniform paste formed is directly stirred at high speed (1000-1200 r / min) until the fineness is ≤50µm;

[0078] Findings: Stirring time greater than 2 hours results in low production efficiency; even when the component fineness reaches ≤50µm, the resulting putty is prone to settling, and a clear liquid remains on the top layer after storage; in addition, the putty film obtained after coating is relatively rough and difficult to spread evenly; and when more than 0.5mm of putty is applied at a time, pores are easily observed on the surface of the resulting putty film (observed after sanding).

Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
