Problems solved by technology

[0003] The current anti-rust paint includes two kinds of oily anti-rust primer and water-based anti-rust paint. The oily anti-rust primer makes it difficult to remove the greasy surface of the material. Although the price is low, it contains toxic substances such as nitrite and chromium nitrate. The danger to the operator is greater; while the water-based anti-rust primer is mainly composed of a metal chelating agent with good effect and a water-based additive. Since the two are only a simple physical mixture, the matching is poor, and the paint is easy to separate after being placed. layer, the paint film is easy to be uneven when spraying, and cannot play a good role in antirust

Abstract

The invention discloses an antirust and anticorrosive fitness equipment primer and a preparation method thereof. The antirust and anticorrosive fitness equipment primer comprises a component A and a component B, wherein the component A includes the following materials: modified epoxy resin, polyvinyl alcohol, sorbitan monooleate, fatty glyceride, tricresyl phosphate, triethanolamine, xylene and bentonite; and the component B includes the following materials: a polyurethane prepolymer, didecyl phthalate, a water removal agent, titanium dioxide, a silane coupling agent A-187 and stannous octoate. The antirust paint provided by the invention is obtained by mixing the component A and the component B, the two components are used cooperatively to achieve a good antirust and anticorrosive effect,also the adhesion is strong, which is determined by the proportion of the components, specifically, cooperative use of all the assistants in the component A not only has good compatibility, but alsocan generate a synergistic superposition of antirust function, the film-forming time is short, the formed film is firmly adsorbed, and in a room temperature environment, water vapor does not seep intometal surfaces, therefore the primer has a good rust removal effect.

Description

technical field [0001] The invention relates to the technical field, in particular to an antirust and anticorrosion primer for fitness equipment and a preparation method thereof. Background technique [0002] The rust problem of fitness equipment has attracted more and more people's attention. Applying paint on fitness equipment can not only achieve the purpose of rust prevention, but also be more beautiful and give people visual enjoyment. However, the current antirust paint has poor adhesion and is very It is easy to crack or peel, has poor mechanical properties, short anti-rust time, and poor anti-corrosion performance, which cannot meet people's needs. Because fitness equipment must not only have an aesthetic effect but also be wear-resistant, especially outdoor fitness equipment that is exposed to the sun, wind and sun, and because the environmental pollution is becoming more and more serious, the fitness equipment with good performance in anti-rust and anti-corrosion ...
