Problems solved by technology

However, conventional anti-rust coatings generally use heavy metal salt pigments as the main anti-rust components. Although these substances have anti-rust effects, they are gradually replaced due to the increasingly prominent environmental pollution problems they bring.

Embodiment 1

[0023] like figure 1 As shown, in the two-necked flask 1, 132 grams of methacrylate-β-hydroxyethyl ester, 98 grams of 98% phosphoric acid, and 20 grams of toluene were mixed, and 0.125 grams of hydroquinone was added, and the system was decompressed so that the system pressure reached 0.06 MPa, start the constant temperature magnetic stirrer 2 to stir (300r / min) and be heated to 60 ℃, constantly the water that is generated is separated by the water separator 3, obtain solution A after reacting 4h (at this moment, conversion rate reaches 60%), in The solvent toluene in the solution A was distilled off under reduced pressure at 0.07Mpa and recovered. After the reaction was completed, the product was taken out and sealed for packaging.

Embodiment 2

[0025] like figure 1 As shown, in the two-necked flask 1, 132 grams of methacrylate-β-hydroxyethyl ester, 98 grams of 98% phosphoric acid, and 20 grams of toluene were mixed, and 0.125 grams of hydroquinone was added, and the system was decompressed so that the system pressure reached 0.07 MPa, start the constant temperature magnetic stirrer 2 to stir (300r / min) and be heated to 60 ℃, constantly the water that is generated is separated by the water separator 3, obtain solution A after reacting 5h (conversion rate reaches 70%) at this moment, in The solvent toluene in the solution A was distilled off under reduced pressure at 0.08Mpa and reclaimed. After the reaction was completed, the product was taken out and sealed for packaging.

Abstract

The present invention relates to a phosphate methacrylate antirust polymerisable emulsion with rust and the preparing technique thereof. The chemical structural formula of the phosphate methacrylate antirust polymerisable emulsion with rust is: and the method is: mixing the methacrylate-beta-hydroxyethyl, phosphoric acid and toluene according to the mass ratio, and adding the hydrochinone with 0.5% of the gross mass of methacrylate-beta- hydroxyethyl and phosphoric acid; decompressing and stirring the system, heating the reactant to 55 to 60 DEG C, separating the generated water from the boiling flask with the water segregator, and the solution A is obtained when the raw material has reacted for 5h; then decompressing the solution A and distilling the dissolvent toluene; taking out the product when the reaction has completed. Except for the common advantage of the common polumerisable emulsion the invention has the unique predominance: namely without adding the iron red or zinc phosphate in preparing the aqueous antirust coating with rust, and processing the antirust with rust function which is not processed by the common emulsion, the invention is a functional polymerisable emulsion and is evidently better than the traditional emulsion.

Description

technical field [0001] The invention relates to a polymerizable emulsifier of methacrylic acid phosphate for preventing rust and rust and a preparation method thereof. Background technique [0002] Water-based antirust and rust coating is a new type of environmentally friendly coating. Compared with traditional solvent-based antirust and rust coatings, it has the advantages of non-toxicity, flame retardancy, aging resistance, chemical resistance, and strong adhesion. However, conventional antirust coatings generally use heavy metal salt pigments as the main components of antirust. Although these substances have antirust effects, they are gradually replaced due to the increasingly prominent environmental pollution problems they bring. Therefore, it is imminent to develop new antirust coatings. [0003] Polymerizable emulsifiers are also called reactive emulsifiers. In their molecular structure, there are both lipophilic and hydrophilic emulsifying groups and a new generation...
