Description
Technical field
The invention belongs to the preparations of polymer composite, the especially production field of carbamide resin modified coating.
Background technique
Spray Polyurea Elastomer Technology experienced three polyurethane, polyurethane-urea and polyureas developing stage.In three kinds of systems
Middle component A is essentially identical, is aromatic series or aliphatic prepolymer and semi-prepolymer, and difference is B component.Spraying is poly-
The B component of urethane is made of terminal hydroxy group resin and terminal hydroxy group chain extender, and contains the catalyst for improving reactivity.
Spraying polyurethane/urea B component is also possible to hold amine resin and amine chainextender group either terminal hydroxy group resin
At typically containing the catalyst for improving reactivity.And the B component of spray polyurea must be by Amino End Group resin and end ammonia
Base chain extender composition, and any hydroxyl moieties and catalyst are free of, a certain amount of dispersing agent and neutral ash 2BL can be contained.
Since the reactivity of Amino End Group compound and isocyanate component is high, it is not necessarily to any catalyst, it can be in room
Temperature or low temperature lower moment complete reaction, thus effectively overcome polyurethane and polyurethane/urea elastomer in the construction process, because
The influence of environment temperature and humidity and the fatal defects for foaming, material property being caused sharply to decline.
Polyurea Spraying integrates the plurality of advantages of the anti-corrosion materials such as coating, rubber and plastics, be at present in the world
One of state-of-the-art aseptic technic.Its technical advantage is mainly manifested in rapid curing, can be in any curved surface spraying without generating stream
Phenomenon is dropped down, gel time is as short as 10s or hereinafter, 10min can reach walking intensity；It is insensitive to temperature, moisture, when construction
It is not influenced by environment temperature, humidity.Polyureas can construct under -28 DEG C of low temperature environment, can also be under moist rainy environment
Construction；100% solid content, meets environmental requirement, does not have smell in construction and use process, is especially suitable for the storage of improper ventilation
The anticorrosive construction of top tank structure and inner wall of the pipe；Primary construction can reach thickness requirement, and overcoming traditional anticorrosive paint must be more
The disadvantage of secondary construction；Coating is fine and close, seamless, can tolerate the long-term corrosion of the media such as water, seawater, acid, alkali, salt, oil, chemically-resistant
Medium and soil erosion ability are very prominent；High mechanical strength, elongation is good, and shock resistance is good, in temperature alternating and external force
Not cracky under percussion；Adhesive force is good, and adhesive force is greater than 10MPa on the steel of sandblasting to Sa2.5 grades, is used for a long time not
It falls off；Breakdown voltage resistant up to 20kv/mm or more is good with cathodic protection matching；Without catalyst, resistance to UV aging
Can be good, not dusting is used for a long time outdoors, does not crack；It is wide using temperature, it can be used for a long time at -50~+121 DEG C, modification is resistance to
High temperature polyureas can be 150 DEG C or less the long-time services the advantages that.
Polyurea Spraying has brilliant physical property and workability, is a kind of novel application techniques.It can be with
Substitute traditional polyurethane, epoxy resin, glass reinforced plastic, FBE and polyolefins compound completely or partially, chemical anticorrosion,
The industries such as pipeline, building, ship, water conservancy, traffic, machinery, mine be wear-resisting have broad application prospects.
Lining and coating two major classes are generally divided into for chemical metallization storage tank anti-corrosion material.Common lining has rubber lining
In, plastic lining and glass reinforced plastic lining etc..Rubber lining generally uses natural rubber or synthetic rubber, can make at normal temperatures and pressures
With.The disadvantage is that need scene heating vulcanization, construction technology is sufficiently complex, quality it is difficult to ensure that.Plastic lining is generally prefabricated section
Shape material applies the special barbola work of man-hour requirement, and seam crossing easily causes to leak, so as to cause global failure.Glass steel lining
In use hand paste technique, smell is big, pollution environment, and multiple tracks is needed to construct, and construction quality is difficult to ensure.
Traditional anticorrosive paint has the advantages that easy for construction, can use in inner wall or outer wall.But these coating systems one
As there is hardness have a surplus toughness deficiency, easily crack under thermal stress or percussion, premature cracking may cause storage
Liquid leakage, repairing and maintenance cause expense to increase；System contains organic solvent, is harmful to the human body, pollutes environment, solvent volatilization
The pin hole of generation will cause the infiltration of corrosive medium；It must be constructed using multiple tracks, the disadvantages of period is long, low efficiency.
Polyureas spraying technology efficiently solves above-mentioned problem, and applying in the inside and outside wall antiseptic project of steel storage tank has
Apparent technical advantage, Daqing oil field, Shengli Oil Field, Xinjiang Oilfield, Qilu Petrochemical, Lanzhou Petrochemical, Yueyang petrochemical industry original
It is applied successfully in the projects such as oil tank, heavy oil tank, Water Tank and hydrochloric acid tank car.
In addition, SPUA technology can also be used in the chemical storage tank for having thermal requirements, the protective layer as insulating layer.Traditional side
Method is galvanized iron sheet to be wrapped up outside polyurethane foam, but existing seam is easy to cause into water, and foam is corroded aging quickly.
And anti-corrosion and waterproof can be played a dual role of using SPUA technology, and it is seamless, it is both artistic and practical.
To prevent industrial chemicals from revealing, storage tank cofferdam is had around certain chemical storage tanks.The storage tank cofferdam of early stage is very
It is simple and crude, it is usually enclosed and is made by concrete or cob wall, rubble is spread in bottom.Once a large amount of leakages occur for raw material, cofferdam can
Interim storage, but the industrial chemicals revealed on a small quantity can penetrate into soil, cause serious pollution to soil.With developed country pair
Environmental protection is increasingly paid attention to, it is desirable that storage tank cofferdam must be completely enclosed with soil protection.Plastic lining is once in storage tank cofferdam
Using, have the advantages that antiseptic property is good, but complicated construction technique, it is especially non-in complex-shaped, more than pipe fitting place construction
It is often difficult.In addition, the plastic lining after construction there are a large amount of seams, leakage is often resulted in, however polyureas can be resistant to water and most
Number chemical mediators erosion, and have the characteristics that it is pollution-free, do not trickle, construct it is fast.More importantly polyureas bullet after spraying
Property body is seamless, flexibility is good, and elongation is up to 300% or more, the hair cracks on concrete substrate can be connected to one
It rises, antiseep excellent.Currently, polyureas widely applied on external concrete storage tank cofferdam Pacific Northwest with
And the application of Alaska Sector shows that polyureas can be subjected to harsh weather test.In addition to storage tank cofferdam, similar application neck
There are also the protection on the surfaces such as chemical industry trench, power plant gutter and ground impervious barrier in domain.
Polyureas represents the trend of international newest aseptic technic.Many famous pipeline engineering all make in the world at present
With polyureas or/in conjunction with polyurethane foam for the oil-gas pipeline that needs to keep the temperature.
With the Popularization And Development of polyureas technology, the superiority of polyureas technology, which has, has obtained the common recognition of people.Soon
In the future, polyureas will become together one of the main anti-corrosion material of pipeline outer wall with clinkery epoxy powder, 3PE.
SPUA material is also widely used as the inner wall anti-corrosive of ductile iron pipe, steel pipe and pipe of cement.Reaching 50 years makes
With the service life, cast iron pipe or steel pipe inner wall must carry out preservative treatment, and common method was lining cement mortar in the past.Cement mortar
Pipe lining with the longest history, but there are stress shrink after it is easy to crack, surface defect (such as pitted skin, sand cave, hollowing) is more；
Cement-mortar lining will cause the raising of dissolved matter content, and hardness changes, NH3It is precipitated, water quality is caused to alkalize；Water
Unstability also will affect the disadvantages of cement mortar.
As CO in water2Superequilibrium quantity concentration, which reaches 7mg/L, will lead to that mortar is impaired, and sand grains is lost, and influence water quality.SPUA material
Material, which is used as cast iron pipe inner wall anti-corrosion material, has adhesive force good, does not crack, corrosion resistance is strong, long service life；Surface is smooth, water
The power coefficient of friction resistance is fewer than concrete pipe and steel pipe, can improve emptying effectiveness.Under conditions of identical caliber, the power and energy of pump are saved
20% or more source, substantially reduces operating cost；Non-scaling, water quality will not be stain by the mushroom microorganism in water or oxidation and rusting,
The advantages that not generating secondary pollution, being able to maintain permanent carrying capacity and constant clean water quality degree.
