Embodiment 1

[0029] Synthesis of Trifluorooctyl Acrylate

[0030] Add 2g of acrylic acid, 0.05g of hydroquinone, 9g of trifluorooctyl alcohol and 0.22g of p-toluenesulfonic acid into the container, and stir at 80°C for 6h. Cool to room temperature, wash the product with 3wt% NaOH solution, wash with distilled water three times repeatedly, and let stand to separate the liquids. The organic phase was distilled under reduced pressure to obtain trifluorooctyl acrylate, which was stored for use.

Embodiment 2

[0032] Preparation of Copolymer S1

[0033] In a three-neck flask equipped with a reflux condenser and a dropping funnel, first add 0.3g glycidyl methacrylate, 10g trifluorooctyl acrylate, 0.1g butyl acrylate, 0.5g azobisisobutyronitrile and 20ml Toluene solvent, stirring at 80°C under nitrogen protection. At the same time, 0.6 g of glycidyl methacrylate, 20 g of trifluorooctyl acrylate, 0.2 g of butyl acrylate and 1 g of azobisisobutyronitrile were uniformly mixed, and then transferred to the dropping funnel. The mixture was added dropwise while stirring, and the dropwise addition time was 2h; after the dropwise addition was completed, the temperature was kept for 4h. The solvent was removed under reduced pressure. Copolymer S1 is obtained.

Embodiment 3

[0035] Copolymer S2 preparation

[0036] Method is identical with embodiment 2. The difference is that azobisisobutyronitrile is replaced by dibenzoyl peroxide.

Abstract

The invention relates to a method for preparing an epoxy-fluorinated acrylate polymer coating agent. An epoxy-fluorinated acrylate polymer is obtained by a copolymerization reaction of perluorooctyl acrylate, acrylate esters and glycidyl methacrylate. The method comprises the following synthesis steps: (1) preparing perluorooctyl acrylate; (2) preparing the epoxy-fluorinated acrylate polymer. The epoxy-fluorinated acrylate polymer prepared by the invention is subjected to heat curing with steel plates containing amino functional groups. Compared with the current commercially available organosilicon waterproofing agent, the epoxy-fluorinated acrylate polymer coating agent disclosed by the invention has excellent repellency to water and oil and wiping resistance.

Description

technical field [0001] The invention belongs to the field of substrate surface treatment, and relates to the preparation of fluorine-containing acrylic materials with epoxy groups by free radical addition, especially the preparation of an epoxy-fluorine-containing acrylate polymer coating agent applied to steel plates method. Background technique [0002] With the progress and development of society, steel plate materials have been widely used in our lives, and the performance requirements for steel plate materials are also increasing. We not only need a large amount of steel materials in industries such as automobiles, aerospace, and construction, but also in daily life. Steel materials are also indispensable in family life. In stainless steel materials in kitchens and bathrooms, water stains and oil stains are usually stained on the surface of the material, so it is very important to improve the waterproof, oil-proof, stain-proof and wear-resistant properties of the steel...
