Description
Technical field
The invention belongs to technical field of paint preparation, more particularly to a kind of low temperature resistant fireproof coating and preparation method thereof.
Background technology
At present, petrochemical industry production, pipeline, storage facilities fire risk is big, fire protection requirement is high, and often low temperature store
Some materials, and leakage accident once occurs for these equipment, then cryogenic media will be full of equipment surface moment, and it applies fire prevention and applied
Can material effectively protect institute's automatic doubler surface glouer surface, improve its fire endurance, by the condition of a disaster control at initial stage when directly affecting accident rescue
Validity, so as to the generation for the sexual behavior event that averts a calamity, the person and property safety are protected to greatest extent.But existing fire prevention
For coating in the presence of when running into low temperature oil product medium, its cohesive force is vulnerable to influence, if because cohesive force is not enough prevented fires outside occurrence of equipment
The problems such as entirety of coating comes off and destroyed, the fire protecting performance of coating will be directly affected.
CN201310245272.3 discloses a kind of expanding fire-proof paint, the patent utilization resin and catalyst, into charcoal
Agent, fire retardant, foaming agent combine, so as to improve the low-temperature curable performance of its coating；CN201410216328.7 discloses one
Kind of novel tunnel fireproof coating, the patent utilization waterglass and silicate material combine, while it is met fire protection requirement,
Meet low temperature resistant requirement；CN201611244576.8 discloses a kind of elastic fireproof coating and preparation method thereof, the patent utilization
Epoxy resin and curing agent combine, and prepare the fireproof coating of low-temperature setting；Although resinae fireproof coating is at low temperature, it is solid
Change performance to be improved, but use range does not refer in particular to petrochemical field, therefore can not verify that it leads in some petrochemical industry
The demand of domain low temperature storage medium, and run into the cohesive force after low temperature petrochemical industry class medium and absorption affinity also needs to be investigated.
The content of the invention
The technical problem to be solved in the present invention is：In order to which the coating with low temperature resistant fire protecting performance is applied into petrochemical industry neck
Domain, there is provided a kind of low temperature resistant freeze proof fireproof coating, make it not only have well in instantaneous touch low temperature petroleum-type medium
Low temperature tolerance characteristicses, and its fire protection flame retarding, caking property are unaffected, can store cryogenic media in petroleum chemical industry
Place contact, frequently use and never degenerate.
The technical solution adopted for the present invention to solve the technical problems is：A kind of low temperature resistant fireproof coating, includes following
The raw material of parts by weight：Magnesium chloride solution：10~15 parts, dicyandiamide：15~20 parts, (epoxy resin is low temperature resistant ring to epoxy resin
Oxygen tree fat)：10~15 parts, natrium nitrosum：10~15 parts, lithopone：2~5 parts, talcum powder：5~10 parts, DAA：20~
30 parts, anti-settling agent：2~5 parts.
Further, the anti-settling agent is：Tissuemat E or superfine silicon dioxide.
Further, the mass concentration of the magnesium chloride solution is：25%~30%.
Present invention also offers a kind of preparation method of low temperature resistant fireproof coating, including following preparation process：
(1) after the magnesium chloride solution prepared heating is boiled, it is cooled to room temperature and adds dicyandiamide, stand 3h~5h,
Obtain mixed solution；
(2) epoxy resin, natrium nitrosum, lithopone, talcum powder and anti-settling agent are fully ground well mixed, mistake in proportion
200 mesh sieves, stir, be then slowly added into mixed solution obtained by step (1), 2000 after adding DAA solvent
50min~60min is stirred under rev/min, it is scattered to stir evenly, produce low temperature resistant fireproof coating.
The inventive method is during low temperature resistant fireproof coating is prepared, because magnesium chloride solution is in heating boiling part
In, the rise of H ion concentrations and CL ions bindings generation HCL, vapor away, be left Mg2+And OH-Hydrolysis combines generation fire retardant hydrogen-oxygen
Change magnesium, then add a certain amount of dicyandiamide with foaming agent and curing agent dual-use function, when making coating chance fiery, dicyandiamide meets fire
Decompose and produce ammonia, ammonia can dilute the concentration of fuel gas caused by decomposition, and expand coating, be passed through after coating expansion
The cellular thermal insulation layer that high temperature cabonization is formed, the magnesium hydroxide with reference to caused by hydrolysis of magnesium chloride so that coating has anti-well
Fiery flame retardant effect.In addition, for coating while with fireproof flame-retardant effect, the dicyandiamide component of addition plays its solidification when meeting fiery
The effect of agent makes the cohesive force of coating stronger, is not easy it protected from environmental；The water reducer natrium nitrosum of addition with it is low temperature resistant
Epoxy resin is used cooperatively, and can be effectively dehydrated, and can be obviously improved cryoprotective effects of the coating under low-temperature operation environment, so as to
Further improve the low temperature tolerance characteristicses of coating.Also, this product is also added vertical with preferable covering power, alkali resistance and mobility
Moral powder so that the cohesive force of coating is stronger, be less susceptible to it is affected by environment, contribute to extend coating service life.
Present invention also offers the application of low temperature resistant fireproof coating, the coating is used for petroleum chemical industry storage cryogenic media
Place.
The beneficial effects of the invention are as follows：Inventive formulation is reasonable in design, and technological operation is easy, by heating magnesium chloride solution
The magnesium hydroxide with flame retardant effect is formed, then in the synergy of the dicyandiamide with foaming agent and curing agent dual-use function
Under, fireproof flame-retardant effect when coating meets fiery can be significantly improved, while the cohesive force of coating is also improved, ensure it not by ring
The influence in border；Add natrium nitrosum to be used cooperatively with low temperature resistant epoxy resin, can effectively lift coating under low-temperature operation environment
Cryoprotective effects, so as to further improve the low temperature tolerance characteristicses of coating；Add lithopone so that the cohesive force of coating is stronger, helps
In service life of the extension coating in petrochemical field.
Low temperature resistant freeze proof fireproof coating fire insulation performance produced by the present invention is good, has excellent lower temperature resistance and fire-retardant
Property the advantages that, and material price is cheap, is readily available, and paint making process is convenient；To scribble the present invention prepare it is low temperature resistant
After uniform smearing thickness is 1mm castor oil 24h on the steel plate of freeze proof fireproof coating, it is -50 ± 2 DEG C to be placed in temperature, and humidity is
In 50~55% control room after 48 hours, small steel plate is taken out, it was observed that coating surface does not occur to lead because of supercooling, humidity
Peeling, protuberance and the obscission of cause；In addition, being tested again through oxycetylene flame combustion, 10 minutes unburned；After low-temperature test
Coating, its coating fire resistance remains to meet fire protection requirement, therefore the present invention has preferable low temperature resistant fire protecting performance.
