Problems solved by technology

The anti-corrosion methods currently used are mainly zinc-rich paint or ordinary alkyd paint, epoxy paint, etc. These paints generally can only last for 273 years. Due to defects such as poor anti-corrosion performance and low durability, they have become increasingly Can not meet people's needs; and the traditional red lead antirust paint (can last 3 to 4 years), due to toxic pollution and environmental hazards to human health, has been banned in many areas; although there are already high-quality coatings with a life span of 8 to 10 years Imported anti-corrosion coatings, but the price is generally above 40

Abstract

The invention discloses a nano particle compound type anticorrosive coating and a preparation method therefor. The nano particle compound type anticorrosive coating comprises the following components in parts by weight: 20-30 parts of polybutylene, 2-8 parts of maleic anhydride, 3-5 parts of acrylate resin, 0.2-0.6 part of dibenzoyl peroxide, 2-4 parts of pentaerythritol, 5-10 parts of nanosilicon dioxide, 1-4 parts of nanometer titania, 0.35-0.88 part of sodium dodecyl benzene sulfonate, 1-5 parts of amino silicon oil, 2-6 parts of diethylenetriamine, 3-5 parts of polystyrolsulfon acid, 1-5 parts of carboxyethyl cellulose, 5-10 parts of maleic anhydride, 1-3 parts of fire retardant, 1-3 pats of fireproof staple fiber, 2-5 parts of foaming agent and 0.8-2.5 part of reinforcing agent. The rigidity and strength of the coating are high, the adhesive force of a priming paint and a base material is high, and the mechanical strength is improved; the coating is more compact after coating and is unlikely to peel off, and the corrosion resistance is reinforced.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a nanoparticle composite anticorrosion coating and a preparation method thereof. Background technique [0002] Since steel structures are widely used in engineering construction and industrial production, in order to ensure that the outdoor steel structure facilities such as houses, pipes, street lights, and bridges can maintain a service life of more than decades, usually every 2 to 5 years The surface of these steel structures must be painted. The anti-corrosion methods currently used are mainly zinc-rich paint or ordinary alkyd paint, epoxy paint, etc. These paints generally can only last for 273 years. Due to defects such as poor anti-corrosion performance and low durability, they have become increasingly Can not meet people's needs; and the traditional red lead antirust paint (can last 3 to 4 years), due to toxic pollution and environmental hazar...
