Description
Technical field
The present invention relates to C09D coating compositions in IPC classification, in particular for the asphalt caulk of container base antirust.
Background technique
It is organic molten that diluent, modifying agent, drier etc. is added using pitch and coal tar as primary raw material in usual asphalt caulk
Agent composition.The proportion of primary raw material is generally because that weather, temperature, use environment are different is different, and the use of modifying agent is on demand not
It adds together.Its characteristic includes: that heat resistance is poor, and drying time is short, and favorable anti-corrosion effect has excellent weather resistance；Suitable for high temperature,
Wet, chemical, air pollution and seashore salinity height etc. be easy to the iron structure of corrosive environment, electrified railway system, ship, bridge and
All kinds of zinc-plated equipment iron pipes, wave plate, zinc-plated steel frame structure protective coating, be chiefly used in underground piping antiseptic project.
Chinese container in 1994 has been more than the South Korea for being known as " container kingdom " at that time, Chinese container with
Very fast speed development, China has been at present the container production big country to rank the first in the world.Container is international fortune
Defeated and logistics specific purpose tool, the overwhelming majority are steel structure.Since the transport of container is travelled to and fro between land and ocean,
It is required that have stronger anticorrosive property and temperature-change resistance (- 40~70 DEG C), while also requiring good decorative property, non-discolouring, not dusting, resistance to
Abrasion, damage resistant, impact resistance etc., and it is amenable to the test of mal-condition.Container industry requires container asphalt caulk at least 3 years
In above antirust time limit, it can be subjected to 40-70 DEG C of jump in temperature, there is well adapting to property to environment, severe item can be subjected to
The test of part.Just to the protection of the metal structure in harsh corrosive environment, more stringent requirements are proposed for this, including collection
Vanning bottom, general standard requirement, container pitch chassis paint spraying film thickness generally require to be 200 μm.
Inland container bitumastic is all based on solvent based coating at present, it contains a large amount of organic volatile
Object VOC (Volatile Organic Compounds), most of these organic volatiles are inflammable and explosive noxious material, no
Only pollute environment, waste of energy, and worker's construction environment is severe, seriously endangers the health of construction personnel, to the mankind and
Environment brings multiple harm.Such as Chinese invention patent application CN200510136609.2 discloses one kind for metal structure
Part and the etch-proof long-acting anticorrosive metal paint of metal equipment and its manufacturing process, by modified high-molecular organic compound coal tar
Pitch, organic polymer resin, antirust agent and auxiliary agent are blended, and curing agent is added after agitated, grinding, adjustment viscosity and forms, it
With extremely excellent super-weathering resistance energy and corrosion resistance, can operation under the conditions of band rust, band water, band greasy dirt, can answer extensively
For antiseptic projects such as metal component, building, underground engineering and ships under various environment.But the technical solution application effect
It is still to be tested.
Being correspondingly improved technical solution also has a small amount of disclosure, such as:
201210005168.2 Guangzhou Jointas Chemical Co., Ltd. of Chinese patent application and South China Science & Engineering University disclose one
Kind aqueous asphalt imitation anticorrosion coating for container chassis and preparation method thereof, by weight percentage, raw material is by with the following group
Divide and constitute: tap water 5-13%, aqueous acrylic emulsion 46-62%, rust resisting pigment 10-15%, constitution filler 15-22%, preventing
Heavy agent 0.6-1.0%, wetting dispersing agent A 0.05-0.2%, wetting dispersing agent BOT0.2-1.0%, coalescing agent 4-6%, disappear
Infusion 0.1-0.3%, pH adjusting agent 0.2-0.4%, salt spray resistance auxiliary agent 0.4-0.8%, anti-flash rusting agent 0.1-0.2% and thickener
0.1-0.7%.Similar product is difficult to reach spraying film thickness requirement through overtesting.
Summary of the invention
The object of the present invention is to provide a kind of special container bottom antirust asphalt caulks, and the coating is environment-protecting and non-poisonous, at low cost,
Construction is simple, rust-proof life limit for length, convenient in processed surface direct spraying.
The purpose of the present invention will be realized by following technical measures: formula are as follows:
Refine low smell solvent: 5-30%
70# road asphalt: 10-40%
Rust-proofing wax: 1-10%
Base oil: 0.2-5%
Plasticizer: 0.2-5%
Organobentonite: 0.2-5%
Activator: 0.2-5%
Dicalcium powder: 10-40%
The step of preparation method includes:
7. in a kettle, pitch is added in solvent-refined oil, heats and be sufficiently stirred, 90 ± 10 DEG C of temperature, stirring
Time 2 h, double of product are detected, and are carried out again in next step after chemical examination is qualified.
8. rust-proofing wax is preheated in drying chamber, after it becomes liquid, slowly putting into, temperature is controlled at 55-65 DEG C,
Mixing time 25-35 minutes.
9. successively putting into base oil and plasticizer, temperature is controlled at 55-65 DEG C, is stirred 25-35 minutes.
10. organobentonite is slowly put into batches above reaction kettle, meanwhile, blender need to be stirred ceaselessly, temperature control
At 55-65 DEG C, mixing time 25-35 minutes.
Activator is put into, the amount of investment need to be accurate to as unit of g, and it is anti-that with organobentonite chemistry can occur for activator
It answers, temperature control is at 55-65 DEG C, mixing time 45-55 minutes during this.
Dicalcium powder is put into, stirs evenly, is cooled to room temperature, completes preparation.
Especially, refining low smell solvent is D60, and base oil is No. 10 machinery oil, and plasticizer is adipic acid dibutyl ester, living
The ethyl alcohol that agent is 95%.
Advantages of the present invention and effect: selecting good refining solvent and road asphalt, while adding rust-proofing wax, plasticity
The preferable additive of energy, cooperates with organobentonite, dicalcium powder etc., adjusts suitable viscosity, to facilitate the construction at scene, solvent
The protective film of the black bright of long-term anticorrosion and resistance to harsh conditions is formed after volatilization in container base.It is capable of providing at least
In 5 years or more antirust time limits, cost is reduced, extend the service life of container, while can guaranteed at -30 DEG C and 100 DEG C
Under the conditions of still there are preferable anti-rust and corrosionproperties, have an excellent anticorrosive property, solvent Environmental Safety, product is without a huge sum of money
The harmful substances such as category, storage is convenient, construction is simple, and performance is stablized.
