manufacture example 1

[0098] Add 280 g of isopropanol to the reaction vessel, add dropwise 40 g of styrene, 96 g of methyl methacrylate, 40 g of n-butyl acrylate, 120 g of ethyl acrylate, and 2- A mixture of 48g of hydroxyethyl ester, 28g of propylene ester and 8g of azodimethylvaleronitrile, then add 4g of azodimethylvaleronitrile, and keep it at 80°C for 1 hour for reaction to obtain ethylene copolymer resin No.1 .

[0099] This ethylene-based copolymer resin No. 1 had a weight average molecular weight of about 25,000, an acid value of 55 mgKOH / g, and a hydroxyl value of 58 mgKOH / g.

[0100] Production Example 2 Production Example of Emulsion No.1

[0101] After mixing 0.4 equivalent of triethylamine with respect to the carboxyl group of 70 parts (solid content) of ethylene-based copolymer resin No. 1 obtained in Production Example 1, mix and disperse, and then mix and disperse 30 parts of Nikalac MX430 (Note 1), Deionized water was slowly added dropwise while stirring, and triethylamine was added to adjust the pH to 7.5 to obtain emulsion No. 1 with a solid content of 10%.

[0102] The difference in solubility parameters between the ethylene-based copolymer resin No.1 and Nikalac MX430 was 0.7.

Abstract

An anionically electrocoated dulled film is prepared through preparing the anionic electrocoating paint from ethene copolymer resin and cross-linking agent through mixing to become emulsion, electrocoating on the surface of Al-alloy workpiece, immersing it in the aqueous solution of high-grade alkylarylsulfonic acid and alkaline compound, applying voltage to it, washing and baking for solidifying.

Description

technical field [0001] The invention relates to a matting anion electrophoretic coating film forming method capable of forming a matting electrophoretic coating film with good productability, mold mark masking property and coating film performance. technical background [0002] In the past, because aluminum has better processability at high temperatures than other metals such as steel, it is relatively easy to obtain mold materials with various cross-sectional shapes by hot extrusion. Various metals are mixed with this aluminum to make an aluminum alloy. [0003] This kind of aluminum alloy has been gradually used as a building material by taking advantage of its original good properties such as light weight, easy processing and good corrosion resistance. [0004] The hot extrusion method of the aluminum alloy is usually to heat a cylindrical aluminum ingot to melt it, then put the melt into an extruder, extrude it on a die with a predetermined cross-sectional shape hole, a...
