Embodiment 1

[0014] A novel alkyd bridge finish paint is prepared by following raw materials in parts by weight: 40 parts of lithopone, 0.5 part of carbon black, 1.0 part of zinc naphthenate liquid (4%), lead naphthenate liquid ( 15%) 0.5 part, 1.0 part of calcium naphthenate solution (2%), 50 parts of long-oil pressed tung oil alkyd resin (160#), 10 parts of turpentine oil.

[0015] The method for making the above-mentioned new alkyd bridge topcoat: mix and stir all the raw materials in the required formula at high speed according to the formula ratio, grind until the fineness is 20-30 μm, and then filter and pack.

Embodiment 2

[0017] Novel alkyd bridge finish paint is prepared by the following raw materials in parts by weight: 30 parts of lithopone, 1.0 part of carbon black, 1.5 parts of zinc naphthenate liquid (4%), lead naphthenate liquid (15% ) 2 parts, 1.5 parts of calcium naphthenate solution (2%), 60 parts of long-oil pressed tung oil alkyd resin (160#), 15 parts of turpentine. Others are with embodiment 1.

Embodiment 3

[0019] Novel alkyd bridge finish paint is prepared by the following raw materials in parts by weight: 50 parts of lithopone, 0.1 part of carbon black, 0.5 part of zinc naphthenate liquid (4%), lead naphthenate liquid (15% ) 1 part, 0.5 part of calcium naphthenate solution (2%), 40 parts of long-oil pressed tung oil alkyd resin (160#), 5 parts of turpentine oil. Others are with embodiment 1.

Abstract

The invention relates to a bridge finishing coat, in particular to a novel alkyd bridge finishing coat. The novel alkyd bridge finishing coat is prepared from the following raw materials in parts by weight: 30-50 parts of lithopone, 0.1-1.0 parts of carbon black, 0.5-1.5 parts of naphthenic acid zinc liquid (4 percent), 1-2 parts of naphthenic acid lead liquid (15 percent),0.5-1.5 parts of naphthenic acid calcium liquid (2 percent), 40-60 parts of long oil degree pressure tung-oil alkyd resin (#160) and 5-15 parts of turpentine. The novel alkyd bridge finishing coat is used for steel and bridge surface coating, is a alkyd bridge finishing coat containing the long oil degree pressure tung-oil alkyd resin, and achieves the effects of good weather resistance, abrasion resistance, tough finishing film and good adhesive force and moisture resistance, and the novel alkyd bridge finishing coat can resist atmosphere pollution and is difficult to age and fade.

Description

technical field [0001] The invention relates to a bridge finish paint, in particular to a novel alkyd bridge finish paint. Background technique [0002] With the development of coating technology, heavy-duty anti-corrosion coating has become the mainstream of steel bridge anti-corrosion. In heavy-duty anti-corrosion coatings, the anti-corrosion coating process and coating types are very similar, that is, the coating design is a multi-layer coating system composed of primer, intermediate paint and top coat; the paint types are all epoxy (inorganic) zinc-rich Primer, epoxy mica iron oxide intermediate paint and polyurethane or epoxy or chlorinated rubber topcoat. [0003] The variety of bridge anti-corrosion coatings and the development of bridge coatings are closely related to the development and application of coating resins and anti-rust pigments. Each successful trial of a new resin or anti-rust pigment will replace the previous paint product as a representative coating ...
