Novel salt-fog-resisting paint

Abstract

The invention discloses novel salt-fog-resisting paint and belongs to the field of paint. The paint is prepared from the following raw materials in parts by weight: 3.2 to 4.5 parts of vinyl trimethoxy silane, 1.1 to 2.7 parts of attapulgite, 0.8 to 1.9 parts of sericite powder, 3.7 to 6.8 parts of PVDF (Polyvinylidene Fluoride) latex, 2.4 to 3.2 parts of terpene-styrene resin, 2.1 to 4.8 parts of styrylphenol polyoxypropylene polyoxyethylene ether, 0.8 to 3.1 parts of epoxy butyl oleate and 0.9 to 1.8 parts of polyoxyethylene aliphatate. The paint provided by the invention takes the PVDF latex as a main material so that the paint has good electric insulativity, thermal plasticity and film forming property, extremely stable chemical performance, good corrosion resistance, good salt fog resistance and uneasiness of being combusted; meanwhile, the terpene-styrene resin and the vinyl trimethoxy silane are matched, so that the adhesion performance is enhanced; the sericite powder is added so that the heat-resisting performance is improved; the paint is applicable to wet and hot seaside regions, is durable and has good economic benefits.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a novel salt spray-resistant coating. Background technique [0002] The role of paint is to decorate and protect, protect the surface of the coated object, prevent the erosion of light, oxygen, chemical substances, solvents, etc. from the outside, improve the service life of the coated object, and change the color, pattern, Gloss, texture, etc., improve the aesthetic value of objects. There are various classification methods of architectural coatings, such as interior and exterior wall, floor and ceiling coatings according to the use environment; organic, inorganic and organic-inorganic composite coatings according to the main film-forming substances; water-soluble, emulsion and organic-inorganic composite coatings according to the state of the main film-forming substances Solvent-based powder type; according to the decorative function, it can be divided into flat wall shape, sand wall s...

Problems solved by technology

[0003] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the coating business of metal components is also increasing, especially in industries such as household appliances, instruments and meters, transportation facilities, aluminum profiles, various vehicles, and daily hardware. The coating can provide metal with excellent anti-corrosion protection and decorative properties, but due to the unsatisfactory anti-pollution performance of the existing coatings used in the above fields, various types of dust, dirt and even oil are often attached to the coating; the anti-sticking ability is not good. Ideal, and the coating formed by the existing coating is prone to blistering, cracking, and peeling under the influence of natural conditions such as long-term outdoor exposure, rain, and salt spray. Therefore, the mechanical properties of the coating are not ideal
