Bottom surface universal type alkyd antirust paint and preparation method thereof

Abstract

The invention discloses bottom surface universal type alkyd antirust paint. The bottom surface universal type alkyd antirust paint is prepared from the following components in parts by weight: 25 to 50 parts of alkyd resin, 10 to 20 parts of C9 petroleum resin, 0.4 to 1.5 parts of an anti-settling agent, 0.6 to 1.5 parts of a dispersant, 5 to 25 parts of pigment, 20 to 40 parts of filler, 0.5 to 3 parts of a drier, 0.5 to 2 parts of an anti-skinning agent and 5 to 15 parts of a diluent. The invention further discloses a preparation method of the bottom surface universal type alkyd antirust paint; the preparation method comprises the main steps of adding the raw materials in sequence and uniformly mixing. The bottom surface universal type alkyd antirust paint provided by the invention can be used as a primer and can also be used as finish paint and can dry rapidly; hard dry time is reduced to 4 hours from original 12 hours, and a construction period can be shortened; the hardness, mechanical property and brightness-keeping and color-keeping performance are all greatly improved. The preparation method is simple to operate and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of paint chemical industry, and in particular relates to a general-purpose alkyd antirust paint for bottom surfaces and a preparation method thereof. [0002] technical background [0003] A type of coating that uses alkyd resins made of polyols, polyacids and drying vegetable oils as the main film-forming substance is called alkyd resin paint. This kind of paint has good construction performance, can be dried at room temperature to form a film, and the film is bright and plump, with strong adhesion, flexibility and firmness. However, the alkyd antirust paint made of traditional alkyd resin has slow drying, low hardness, Insufficient coloring stability and other problems cannot meet the market demand for gradual improvement in dryness, hardness, gloss and color retention. Contents of the invention [0004] Purpose of the invention: Aiming at the defects of the prior art, the present invention provides a ge...
