Description

Special-purpose aqueous anticorrosive paint of container and preparation method thereof
Technical field:
The present invention relates to paint fields more particularly to a kind of special-purpose aqueous anticorrosive paint of container and preparation method thereof.
Background technology:
Application of the water-based anticorrosive paint in terms of anticorrosive paint field is in rising trend, such as infrastructure, oil gas and electricity Lixing industry, and industrial tank, ship and chemical industry etc..
Practical application shows that aqueous industrial anticorrosive coating can in extreme conditions be effectively protected steel offer. It is primary solvent since water is for they, water can also be used to clean and dilute water paint, they are almost without solvent taste, together When, lower cost can be also brought to user using water paint, if quick-drying can save the time, low flame properties can reduce insurance Expense, less room ventilation can reduce energy consumption, and not need the cost on solvent and cleaning agent, be matched using signal layer coating Set, can save the expense etc. of downtime and erecting scaffold.
Metal erosion all can cause huge destruction to machinery, equipment etc. every year, economic damage caused by order to reduce corrosion It loses, generally can coat anticorrosive paint in metal surface, play shielding, passivation, electro-chemical protection.With holding for national economy The market scale of supervention exhibition, China's anticorrosive paint has been only second to building coating, occupies second, it is contemplated that arrives the year two thousand twenty China anti-corrosion The market scale of coating will break through 1,000,000 high pointes t.Currently, anticorrosive paint is solvent based coating substantially, containing big in coating The volatile organic compounds (VOC) of amount, it is inflammable, it can cause damages to human body and environment.On March 31st, 2013, Guangdong Province was formal It implements《Aqueous polyurethane anticorrosive paint (bi-component) standard》, which is the first water-based anticorrosive paint standard that China is put into effect; The State Tax Administration of the Ministry of Finance notice from 2 1st, 2015 for Construction State under VOC content more than 420g/L coating levy Receive the consumption tax.The appearance of these standards and regulation embodies attention of the China to environmental problem, promotes coatings industry hydrotropismization Direction is developed, and the structural adjustment of coating industry and the upgrading of product have also been pushed.
Container refers to that there is some strength, rigidity and specification to specialize in the large-scale goods container being used in turn.Use packaging Case transshipment cargo can directly freight in the warehouse of consignor, transport to the warehouse unloading of consignee, more change trains halfway, ship time, without Cargo is taken out out of case and is changed the outfit.The standard dry cargo container of domestic product accounts for 95% of world wide production or more, container production and marketing Amount is always maintained at the first in the world during the last ten years.Container and packaging container of metal manufacturing are a sons under metal product industry Industry occupies an important position in national economy.With the recovery of world economy, the especially height of International Shipping Industry in recent years Speed development, as the mating industry for providing packaging for numerous industries, container and packaging container of metal manufacturing will welcome one The new period of a development.There is also a huge problem of corrosion-resistant, generally uses to spray the special-purpose aqueous anti-corrosion of container for container Coating is achieved.
However, the special-purpose aqueous anticorrosive paint of container in the prior art, it is bad that there are fire retardant performances, and flexibility is not The shortcomings of good.
