Description
Technical Field
The invention belongs to the field of coatings, and particularly relates to an anti-settling paste for a high-solid-content zinc-rich coating and a preparation method thereof.
Background
The zinc-rich coating with high solid content is widely applied to corrosion protection under severe environments such as chemical equipment, engineering equipment in marine environment and the like due to strong corrosion resistance, excellent mechanical property and excellent acid and alkali resistance and organic solvent resistance.
The zinc-rich paint with high solid content has good corrosion resistance, but the zinc powder content is high, generally the zinc powder content is more than 50 percent, because the zinc powder has high density and is easy to settle, and once the zinc powder is settled, a compact zinc powder layer is gathered at the bottom of the packaging barrel, so that the zinc-rich paint with high solid content is difficult to stir and the construction quality of the zinc-rich paint with high solid content is seriously affected.
At present, in order to slow down the sedimentation of heavy fillers such as zinc powder, a thixotropic agent, also called anti-sagging agent, is added into the paint. The thixotropic agent has the function of preventing paint from flowing on an inclined plane or a vertical plane in the construction process and preventing the paint from having uneven upper and lower layers, thereby ensuring the product quality. Conventionally, fumed silica, polyamide wax, bentonite, etc. are used, and a direct stirring and dispersing process is generally adopted. The thixotropic agents can obviously improve the sedimentation of the filler for common paint or sealant, but the improvement of the thixotropic agents for high-solid-content zinc-rich paint is very limited, and a large amount of zinc powder begins to sediment usually after 5 to 10 days, so that the storage period of the high-solid-content zinc-rich paint is seriously influenced. In order to avoid serious sedimentation of zinc powder, a method of independently packaging zinc powder is adopted in some high-solid-content zinc-rich paint, and zinc powder is added when the paint is stirred in construction, so that the zinc powder has two defects, namely, zinc powder belongs to dangerous goods, hydrogen is easily generated when meeting water, explosives are easily formed, the zinc powder is independently packaged, the zinc powder and resin are extremely dangerous, paint coating is started after stirring for a few minutes, zinc powder particle agglomeration is easily generated, the adhesive force of the paint is reduced, and the paint quality is affected.
Disclosure of Invention
The invention aims to solve the technical problem of providing the anti-settling paste which has the advantages of simple preparation method, good dispersibility and simple components and solves the problem of settling of the heavy filler in the zinc-rich paint with high solid content.
The invention also aims to provide a preparation method of the anti-settling paste applicable to the high-solid-content zinc-rich paint.
The technical problems to be solved by the invention are realized by adopting the following technical scheme:
an anti-settling paste for high-solid-content zinc-rich paint is prepared from the following raw materials in parts by weight:
10 to 20 parts by weight of hydrogenated castor oil
20 to 100 parts by weight of organic resin
1 to 5 parts by weight of coupling agent
The anti-settling paste of the zinc-rich paint with high solid content is preferably prepared from the following raw materials in parts by weight: 10-12 parts of hydrogenated castor oil, 50-80 parts of organic resin and 2-3 parts of coupling agent.
The most preferable anti-settling paste of the high-solid-content zinc-rich paint is prepared from the following raw materials in parts by weight: 10 parts of hydrogenated castor oil, 50-80 parts of organic resin and 2 parts of coupling agent.
Wherein, the organic resin is preferably selected from one or more of epoxy resin, liquid polysulfide rubber, phthalate and hydroxyl-terminated polybutadiene.
For zinc-rich paint with strong polarity, such as epoxy zinc-rich paint, the organic resin is preferably epoxy resin, or is preferably common epoxy toughening resin such as liquid polysulfide rubber and phthalate, so that the prepared anti-settling paste has good compatibility with the resin, hydrogenated castor oil can be thoroughly dispersed after the preparation, and other performances of the paint are not affected.
For nonpolar or polar zinc-rich paint such as chlorinated polyolefin paint, the organic resin is preferably hydroxyl-terminated polybutadiene, so that the prepared anti-settling paste has good compatibility with the resin, and hydrogenated castor oil can be thoroughly dispersed after the preparation without affecting other properties of the paint.
The coupling agent is preferably an organosilane coupling agent, such as one or more of gamma-glycidoxypropyl trimethoxysilane, gamma-aminopropyl triethoxysilane and gamma-methacryloxypropyl trimethoxysilane. The adoption of the coupling agent can not cause other bad performances of the coating.
The preparation method of the anti-settling paste comprises the following steps: sequentially adding organic resin and a coupling agent into a double-planetary stirrer, starting stirring blades in the feeding process, and closing the stirring blades after the feeding is finished; adding hydrogenated castor oil, after the addition, starting stirring at the temperature of not higher than 40 ℃ and the vacuum degree of-0.08 MPa to-0.1 MPa, continuously stirring until the mixture is changed from milky white to light yellow transparent, then closing a stirring blade, and releasing a vacuum system; and (3) regulating the temperature to 45-60 ℃ for heat preservation and activation until the mixture is light yellow transparent paste.
Preferably, the rotation speed of the stirring blade is not higher than 25r/min.
Preferably, the heat preservation activation time is more than 24 hours.
Preferably, stirring is continued for at least more than 2 hours after the addition of the hydrogenated castor oil.
The preparation method comprises the following steps: the vacuum degree is kept between-0.08 MPa and-0.1 MPa, otherwise, a large amount of air is brought in during stirring, and the air cannot be removed after the viscosity is increased. In addition, the activation temperature cannot be lower than 45 ℃, the activation cannot be completed when the temperature is too low, the temperature cannot be higher than 60 ℃, and the hydrogenated castor oil can melt, so that the activation process fails.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, after hydrogenated castor oil is fully dispersed and swelled in organic resin, a macromolecular three-dimensional network structure combined with hydrogen bond is formed with an organosilane coupling agent, the anti-settling capability is strong, and the anti-settling agent is further activated at 45-60 ℃, so that the sedimentation of heavy fillers such as zinc powder in the high-solid-content zinc-rich paint can be effectively prevented, the sedimentation problem of zinc powder in the high-solid-content zinc-rich paint can be thoroughly solved, and the formula is simple and the cost is low; the anti-settling paste has simple production process and is particularly suitable for batch production.
The anti-settling paste is directly stirred, mixed and dispersed with raw materials such as resin in the preparation process of the high-solid-content zinc-rich paint, and the anti-settling paste is convenient to use without additional technological processes in the production process of the paint.
