Problems solved by technology

Although there are many kinds of paints, the baking-type paints used on metal surfaces cannot meet the requirements of high hardness and corrosion resistance, and the use effect is not ideal
Especially for steel drums used in packaging, due to the frequent loading, unloading and handling, the paint coating will be scratched, peeled and peeled off in a large area, and the service life is short
In addition, paint problems such as orange peel, pinholes, and craters are prone to occur during spraying, which not only seriously affects the anti-corrosion effect of steel drums, but also affects the appearance of steel drums.

Embodiment Construction

[0031] Add the alkyd resin and pregel into the container at a time according to the total weight of 25-30% and 7-9% and an appropriate amount of amino thinner, stir at high speed for 5-10 minutes, then add titanium dioxide according to the total weight of 30-40%, high-speed After stirring for 20-40 minutes to make it evenly dispersed, use a sand mill to grind and disperse the basin. The dispersion grinding fineness is below 15mm, and the goods are placed in a large basin of a container, and 4-7% butanol and xylene are added according to the total weight percentage. 4-7%, epoxy resin 5-8%, n-butanol etherified melamine formaldehyde resin 10-13%, adhesion promoting resin 2-4%, surfactant 0.1-0.5%, acrylate leveling agent 0.01 -0.1%, after stirring evenly, the qualified product of the present invention is obtained.

Abstract

The invention discloses roasting type alkyd amino special steel drum paint and a preparation method thereof, and relates to the paint industry; alkyd resin, preformed gel and amino thinner are added into a container to be stirred at high speed; titanium dioxide is added in; the obtained paint paste is ground and dispersed by the pouring tray of the sander with dispersing and grinding grain size of below 15mm, and then poured into the large basin of the container; and then butanol, xylene, epoxy resin, n-butanol etherified melamine resin, adhesion promoting resin, interface activator and agent are added into to be stirred evenly, so as to obtain the qualified product of the invention finally.

Description

Technical field [0001] The invention relates to the paint industry, in particular to a baking-type alkyd amino paint specially used for steel drums and a production method thereof. Background technique [0002] At present, the application fields of paint are very extensive. No matter in large-scale mechanical equipment, bridges, ships, or various metal products, paint is generally used as an anti-corrosion layer for anti-corrosion protection. Although there are many kinds of paints, the baking-type paints used on metal surfaces cannot meet the requirements of high hardness and corrosion resistance, and the use effect is not ideal. Especially for steel drums used in packaging, due to the frequent need for loading, unloading and handling, the paint coating will be scratched, peeled and peeled off in a large area, and the service life is short. In addition, paint problems such as orange peel, pinholes, and craters are prone to occur during spraying, which not only seriously af...
