Description
Technical field
The present invention relates to C09D coating composition in IPC classification, in particular for the asphalt caulk that container base is antirust.
Background technology
Generally asphalt caulk is with Colophonium and coal tar as primary raw material, adds the organic solvents such as diluent, modifying agent, drier
Composition.The proportioning of primary raw material is typically different because weather, temperature, use environment are different, and the use of modifying agent presses demand not
Add together.Its characteristic includes: thermostability is poor, and drying time is short, and favorable anti-corrosion effect has excellent weather resistance；It is applicable to height
Warm, wet, chemical, air pollution and seashore salinity high be prone to the iron structure of corrosive environment, electrified railway system, boats and ships,
Bridge and all kinds of zinc-plated equipment iron pipe, wave plate, the protective coating of zinc-plated steel frame structure, be used for underground piping antiseptic project.
The container of China in 1994 has exceeded the Korea S being known as " container kingdom " at that time, and the container of China is to fly
Fast speed development, China has been the container production big country ranked the first in the world at present.Container is international transport
With the specific purpose tool of logistics, the overwhelming majority is steel structure.Owing to the transport of container is to travel to and fro between land and ocean,
Require have stronger anticorrosive property and temperature-change resistance (-40～70 DEG C), the most also require good decorative property, invariant color, not powder
Change, wear-resistant, damage resistant, impact resistance etc., and be amenable to the test of mal-condition.Container industry requires container drip
In the blue or green paint antirust time limit of more than at least 3 years, the jump in temperature of 40-70 DEG C can be stood, environment is had and well adapts to
Property, it is possible to stand the test of mal-condition.This just protection to the metal structure being in harsh corrosive environment propose more
High requirement, including container base, general standard requirement, container Colophonium underframe paint spraying thickness typically require be
200μm。
Inland container bitumastic is all based on solvent based coating at present, and it contains substantial amounts of organic volatile
VOC (Volatile Organic Compounds), these organic volatile great majority are inflammable and explosive noxious substance, no
Only polluting environment, the waste energy, and workman's construction environment is severe, serious harm workmen's is healthy, to the mankind
Multiple harm is brought with environment.Such as Chinese invention patent application CN200510136609.2 discloses a kind of for metal
Structural member and the etch-proof long-acting anticorrosive metal paint of hardware and manufacturing process thereof, by modified high-molecular organic compound
Coal tar pitch, organic polymer resin, antirust agent and auxiliary agent are blended, agitated, grind, adjust and add firming agent after viscosity
Forming, it has extremely excellent extra-weather-proof performance and decay resistance, can become rusty at band, operation under the conditions of band water, band greasy dirt,
Can be widely applied to the antiseptic projects such as the hardware under various environment, building, underground engineering and boats and ships.But this technical side
Case application effect is still to be tested.
It is correspondingly improved technical scheme and also has a small amount of open, such as:
Chinese patent application 201210005168.2 Guangzhou Jointas Chemical Co., Ltd. and South China Science & Engineering University disclose a kind of collection
Vanning underframe aqueous imitates Colophonium anticorrosive coating and preparation method thereof, and by weight percentage, its raw material is by following components structure
Become: tap water 5-13%, aqueous acrylic emulsion 46-62%, rust resisting pigment 10-15%, body constitution filler 15-22%,
Anti-settling agent 0.6-1.0%, wetting dispersing agent A 0.05-0.2%, wetting dispersing agent BOT0.2-1.0%, coalescents 4-6%,
Defoamer 0.1-0.3%, pH adjusting agent 0.2-0.4%, salt spray resistance auxiliary agent 0.4-0.8%, anti-sudden strain of a muscle rust agent 0.1-0.2% and
Thickening agent 0.1-0.7%.Similar product is through overtesting, and it is difficult to reach to spray thickness requirement.
Summary of the invention
It is an object of the invention to provide antirust asphalt caulk bottom a kind of special container, this coating environment-protecting asepsis, low cost, execute
Work is simple, rust-proof life limit for length, it is simple at the surface direct spraying processed.
The purpose of the present invention will be realized by techniques below measure: formula is:
Refined low abnormal smells from the patient solvent: 5-30%
