Abstract
The invention relates to a corrosion-resistant coating and a processing method thereof and belongs to the technical field of reprocessed raw materials. The corrosion-resistant coating is prepared from components in percentage by weight as follows: 40%-60% of asphalt, 22%-43% of resin, 15%-25% of a curing agent and 2%-3% of filler. The processing method is applicable to processing of the corrosion-resistant coating, and the corrosion-resistant coating has the advantages of high corrosion-resistant effect and the like.
Description
Technical field
The present invention relates to a kind of corrosion resistant coating and its processing method, belong to regenerative raw materials technical field.
Background technology
Pitch is the rheological characteristic with uniqueness by the molecular mixture of various high scores of complex chemical composition, good
Cohesiveness, ageing resistance and water-tight corrosion-proof ability.It is with coal tar pitch epoxy resin when the pitch of early stage is used as anticorrosive paint
Based on coating, but because the paint adhesion is poor, anti-permeability is poor, complicated construction technique, higher to workmen's competency profiling,
Therefore without spread, later stage people begin one's study asphalt anti-corrosion coating, but because hardening time is long, uneven of film
Used as base layer dope.Based on this, the application is made.
The content of the invention
For the drawbacks described above existing for existing conventional pitch, the application provides a kind of high-adaptability modified pitch first.
To achieve the above object, the technical scheme that the application takes is as follows：
A kind of corrosion resistant coating, is made up of pitch, resin, curing agent and inserts, and the percentage by weight of each component is：Drip
Blue or green 40-60 ﹪, resin 22-43 ﹪, curing agent 15-25 ﹪ and inserts 2-3 ﹪.
Further, as preferred：
Described pitch is attached most importance to and hands over 90 ﹟ matrix pitches.
Described resin is resin solubilizer and epoxy resin composition.It is furthermore preferred that described resin solubilizer is increasing
Tough dose, the mixture of diluent.
Described curing agent is the addition product of modified amine, i.e. diethylenetriamines and acrylate.
Described inserts is phenolic resin.
Meanwhile, present invention also provides a kind of processing method of corrosion resistant coating as characterized above：By toughener, dilution
Agent stirs as resin solubilizer, and resin solubilizer is stand-by with epoxy resin high speed shear；Matrix pitch is warming up to
130-145 DEG C, add resin solubilizer and epoxy resin high speed shear thing and stir, constant temperature 1-2h is subsequently adding solidification
Agent and inserts mechanical agitation are uniform, and temperature is maintained at 140-145 DEG C, and constant temperature 2-4h obtains finished product.
Anticorrosive paint curing rate provided herein is fast, high mechanical strength, good insulation preformance, solid are big, viscous containing dividing
Knot power is strong, coating is fine and close, film forming is solid, therefore has anti-permeability higher, and energy is water-fast, the corrosion of resistant to many chemical mediator, and can
The erosion of antimicrobial and plant roots, can be widely used for the antiseptic project of the upper (lower) pipeline in the ground such as gas transmission, oil transportation, water delivery, heat supply,
The underwater sites such as various steel iron facilities and ship, ocean platform, harbour anti-corrosion, insulation also is available for use.
Specific embodiment
(1) resin solubilizer is prepared：The toughener that will measure, diluent are sequentially added in reactor, high speed shear 8
Minute, stir, stand for standby use
(2) after epoxy resin is measured, the resin solubilizer of step (1) configuration is added slowly, high speed shear is uniform, standby
With.
(3) matrix pitch is warming up to 140-145 DEG C, is slowly added to the product of step (2), stirred, constant temperature 1h, so
Curing agent and inserts are added afterwards, and mechanical agitation is uniform, and temperature is maintained at 140-145 DEG C, and constant temperature 2h obtains finished product corrosion-resistant
Coating.
The reagent of different component is tested respectively, the requirement that obtained corrosion resistant coating all meets, it is specific such as table 1
It is shown.
The different formulations end properties table of comparisons of table 1
Restrained by the application many experiments, the function admirable of the corrosion resistant coating meets the items of corrosion resistant coating
Technical requirements；The coating is applied on the water row articles for use such as ferry boat, since the sprayed coating 2 years, without finding any disease.
As can be seen here, the corrosion resistant coating has actual productive value.
Above content is combine that the preferred embodiment of the invention made to provided technical scheme further detailed
Describe in detail bright, it is impossible to assert that the invention specific implementation is confined to above-mentioned these explanations, for the affiliated technology of the invention
For the those of ordinary skill in field, without departing from the concept of the premise of the invention, some simple deductions can also be made
Or replace, should all be considered as belonging to the protection domain of the invention.
