A preparation method of environment-friendly water-based paint special for sewage well covers comprises the following steps:
A. weighing the following components in proportion of the environment-friendly water-based paint special for the sewage well cover for later use: 15-25 parts of water-based acrylic emulsion, 2-5 parts of water-based alkyd resin, 20-30 parts of water, 0.05-0.15 part of defoaming agent, 0.2-0.5 part of dispersing agent, 0.3-0.8 part of pH regulator, 0.5-1.0 part of film-forming additive, 1.3-3.8 parts of flash rust prevention additive, 0.2-0.5 part of carbon black, 1.5-3.5 parts of titanium dioxide, 10-15 parts of heavy calcium carbonate, 8-16 parts of talcum powder, 5-10 parts of mica powder, 0.45-1.2 parts of thickening agent, 2-5 parts of anti-settling thixotropic agent, 0.05-0.15 part of drier and 0.1-0.3 part of scratch resistance additive;
B. adding 35-40% of total water into a container for stirring, adding 13-17% of the total amount of the pH regulator in the stirring process, uniformly stirring, then sequentially adding 40-60% of the total amount of the defoaming agent, 40-60% of the total amount of the dispersing agent, 40-60% of the total amount of the carbon black, 40-60% of the total amount of the titanium dioxide, 40-60% of the total amount of the talcum powder, 40-60% of the total amount of the triple superphosphate, 40-60% of the total amount of the mica powder and 40-60% of the total amount of the anti-settling thixotropic agent, continuously stirring for 20-35min at the speed of 1000-1500r/min, and grinding the mixture obtained after stirring to obtain an early-stage slurry for later use;
C. adding the acrylic emulsion into a container for stirring, sequentially adding 15-20% of the total amount of water, 13-17% of the total amount of the pH regulator, the anti-flash rust agent and the film-forming aid in the stirring process, and stirring at the speed of 400-;
D. adding the water-based alkyd resin into a container for stirring, adding the rest PH regulator and the rest drier into the container, stirring at the speed of 500r/min for 5-10min at 300-;
E. adding the emulsion varnish into a container for stirring, adding the resin varnish during stirring, adding the early-stage slurry after stirring uniformly, sequentially adding the rest defoamer, dispersant, carbon black, titanium dioxide, talcum powder, heavy calcium, mica powder and anti-settling thixotropic agent after stirring at the speed of 400-600r/min for 8-15min, adding the scratch-resistant auxiliary agent for continuous stirring for 8-15min, and then adding the thickening agent into the mixed paint vehicle in batches for stirring to obtain the environment-friendly water-based paint special for the sewage drainage well cover.
The invention has the beneficial effects that:
1. according to the invention, through combination of the optimally designed proportioning of the environment-friendly water-based sewage well lid special paint and the preparation method, all components in the whole formula are matched with each other, so that the mutual cooperation and enhancement effects are achieved, the prepared environment-friendly water-based sewage well lid special paint is non-combustible, non-explosive, small in smell, low in VOC content, excellent in adhesive force, hardness, weather resistance, salt mist resistance and the like, the adhesive force between the paint and a base material can be greatly improved, a high-adhesive-force protective film is formed, and the protective performance is improved.
2. According to the invention, the heavy calcium carbonate and the talcum powder are adopted to replace barium sulfate and composite ferrotitanium powder in the existing water-based paint components, when the heavy calcium carbonate or the talcum powder is independently used as a filler, the weather resistance enhancing effect of the heavy calcium carbonate or the talcum powder on the water-based paint is inferior to that of the barium sulfate or the composite titanium powder, but when the heavy calcium carbonate and the talcum powder are used in a matching way, the heavy calcium carbonate and the talcum powder are compounded and cooperated with other components, and the mutual synergistic enhancing effect is achieved; the well lid rusts usually because the well lid is exposed in the air for a long time and generates oxidation reaction with oxygen, or is corroded by oxygen in water to become oxide, the heavy calcium carbonate is stable in the air and insoluble in water, a compact paint film can be effectively formed to isolate the air of a coated product, the talcum powder has stable chemical property and uniform and strong dispersity of granularity, the interface combination between the paint film and the product is enhanced, and the rust-proof and water-resistant performance of the paint is improved together by matching with other components in the formula.
3. According to the invention, through a large number of experiments, the stirring speed and the stirring time of the preparation method are limited, when the stirring speed is too low, the paint liquid is not easy to disperse, and is easy to agglomerate and coarsen, and when the stirring speed is too high, the demulsification in the aspect of product emulsion is easy to cause, the stirring time is used for fully and uniformly mixing all the components, so that the effects of the auxiliary agent, the thickening agent and the like are optimal, when the stirring time is too short, the stirring is not uniform, and when the stirring time is too long, the product temperature is higher, and part of the auxiliary agent volatilizes, and by limiting the stirring speed and the stirring time of the preparation method, the adverse effect on the final performance of the product caused by the preparation process is avoided, so that the stability of the comprehensive performance of the product is provided.
4.

As shown in tables 1-3, the viscosity and solid content of the aqueous acrylic emulsion adopted by the aqueous paint special for sewage drainage well covers prepared in the comparative example 1 are higher, the viscosity and solid content of the aqueous alkyd resin adopted by the aqueous paint special for sewage drainage well covers prepared in the comparative example 2 are higher, compared with the examples 1-10 of the XG-9021 type aqueous acrylic emulsion and the XG-818B type aqueous alkyd resin produced by the New constant Water optical New Material science and technology Limited company, the aqueous acrylic emulsion and the aqueous alkyd resin have specific viscosity and solid content, so that the XG-9021 type aqueous acrylic emulsion and the XG-818B type aqueous alkyd resin have good compatibility, and the prepared environment-friendly aqueous paint special for sewage drainage well covers has good gloss, thermal storage stability, water resistance, salt water resistance, hardness, adhesive force, impact strength, water resistance, and the like, The performances of neutral salt spray resistance, artificial aging resistance and the like are improved to different degrees, the VOC content is lower, the can opening taste is smaller, and the environmental protection requirement is better met.
As can be seen from comparison between the example 1 and the comparative examples 3 to 7 in tables 1 and 3, the comparative examples 3 and 4 using single talc powder or heavy calcium carbonate have poor water resistance, salt water resistance and neutral salt spray resistance and low hardness, and the aqueous paint for manhole covers prepared by using barium sulfate and composite ferrotitanium powder with good antirust performance in the comparative examples 5 to 7 has lower water resistance, salt water resistance and neutral salt spray resistance compared with the example 1, so that the talc powder, the heavy calcium carbonate and other components in the components have synergistic and synergistic effects, and the antirust and water-resistant performance of the paint is effectively improved.
