Problems solved by technology

[0002] At present, there are many kinds of anti-corrosion plates on the market. Although the existing metal plates or plastic plates can withstand acid and alkali and have good mechanical strength, under the condition of thermal expansion and contraction, the plastic shrinks, which will cause the plastic to fall off and form corrosion.

Abstract

The invention discloses an anti-corrosion board, comprising a substrate (1), characterized in that a polyurethane layer (2) is evenly sprayed on the upper surface of the substrate (1), and the polyurethane layer ( 2) The surface is sprayed with ethylene-acrylic acid copolymer at high temperature to form an upper anti-corrosion layer (3), and a layer of baking varnish is provided on the lower surface of the substrate (1) to form a lower anti-corrosion layer (4). The thickness is 1.3mm, the thickness of the upper anti-corrosion layer is 2mm, and the lower anti-corrosion layer is 25um. The anti-corrosion plate structure of the present invention is provided with double-layer anti-corrosion layers, has very strong anti-corrosion ability, outstanding ability to resist thermal expansion and cold contraction, long service life and strong practicability, and is worthy of popularization.

Description

technical field [0001] The invention relates to an anti-corrosion board. Background technique [0002] At present, there are many kinds of anti-corrosion boards on the market. Although the existing metal or plastic boards can withstand acid and alkali and have good mechanical strength, when they expand with heat and contract with cold, the plastic shrinks, which will cause the plastic to fall off and form corrosion. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an anti-corrosion board with strong anti-corrosion ability, long service life and strong practicability. [0004] The technical solution adopted in the present invention is: an anti-corrosion board, including a substrate, characterized in that a polyurethane layer is evenly sprayed on the upper surface of the substrate, and the surface of the polyurethane layer is sprayed with ethylene-acrylic acid at a high temperature Copolymer to form an upper a...
