Ratio is added in paint mixing cylinder, after mixing up to curing agent finished product.
The performance of anticorrosive paint made from embodiment 3 detect as follows:
Experimentation:
One, anticorrosive paint sample made from embodiment 3 is tested, sample is proportionally deployed to preparation and brushes examination
Sample；
One detection project sample testing specification of table
Two, template status adjustment
Template after all brushed is placed under the conditions of constant temperature and humidity and carries out status adjustment for 24 hours, impact resistance, adhesive force,
Hardness project can be detected, after adjusting 168h, chemically-resistant stabilization, wearability, salt fog resistance, resistance to original sewage, resistance to crude oil, gas
Bubbling, high temperature and pressure test can be tested.
Three, performance test
3.1 impact resistances test uses impact tester and 4 times of magnifying glasses, by the good test plate (panel) of status adjustment as impact test
On device, the metal impact head of pull-up impactor weight weight leading portion after certain altitude, release surface of the paint film impact to be formed it is recessed
Whether slot has crackle with amplification sem observation groove, if flawless determines qualification, and calculates impact force with weight pull-out altitude,
Units of joules.
Method adhesion-force tester is pulled open in the test use of 3.2 adhesive force, and the template adjusted is bonded with survey using adhesive
Spindle special is tried, after bonding for 24 hours to status adjustment at room temperature, using method adhesion-force tester drawing spindle is pulled open, works as spindle
It pulls open in a flash, instrument can automatically record pulling-off force, and show on the electronic display screen, data, that is, adhesive force test at this time
Value, unit megapascal.
3.3 chemical-resistant stabilities, configuration volume fraction are 10%NaOH solution, 10%H2SO4Solution, 3%NaCl solution.
The good template of status adjustment is sealed to the position for applying 5 millimeters of test plate (panel) edge with rosin, regulates test plate (panel) entrance in advance after sealing
In chemical reagent, and the appearance for impregnating template is recorded once a day, checks it is whether coating is complete, if there is blistering, has and fall off,
It is kept for 90 days, process deadline is to there are the defective modes such as blister, fall off as foundation.
Then 3.4 wearability tests are placed in again by the sample for the state that regulates as weight before assay balance test experiments
On paint film abrasion instrument, sample load 1000g is set, abrasion instrument revolving speed 60r/min, CS15 grinding wheel after rotating 1000r, are tested real
Rear weight is tested, forward backward averaging of poor quality is abrasion loss, characterizes the wearability of material.
The template for the state that regulates is placed on pencil hardometer by 3.5 hardness tests, 2H pencil is used first, by pencil
At least 7mm is pushed on paint film with 45 degree of angle of angle, checks whether paint film has scratch after wiping, if can be more without scratch
Pencil with high hardness is changed, if there is the low pencil of the replaceable hardness of scratch, retest detects hardness range.
The sample regulated is being marked cross using blade, as in salt spray test chamber, opened by 3.6 salt fog resistances
Salt spray test chamber is opened, whether observation cross periphery paint film, which has, after a certain period of time falls off, to observe obscission for the first time
To test deadline.
Oilfield sewage and crude oil are contained in road container, as thermostatted water liquid furnace, and are pressed by 3.7 resistance to oilfield sewages, resistance to crude oil
Experimental temperature is adjusted according to requirement of experiment, the experiment template for the state that regulates is subjected to edge sealing using resin, is impregnated after the completion of edge sealing
In sewage and crude oil, and time and state are recorded, whether observation paint film coating is complete, if having blistering or fall off, by test
Time requirement is kept, and process deadline is to there are the defective modes such as blister, fall off as foundation.
3.8 resist bending tests test the template for the state that regulates on crooked experiment device, when test plate (panel) is with certain condition
After bending, whether observation flexure plane has crackle or breakage, to judge whether resistance to bend(ing) can qualified without damaged, flawless phenomenon,
When qualification, bending angle is set to complete the performance test results.
The experiment of 3.9 gas bells, by the sample for the state that regulates as in autoclave, being passed through pure nitrogen, and passes through tune
It is 8 ± 0.5 megapascal that pressure device, which adjusts pressure, after keeping for 24 hours, the quick pressure releasing in 1 minute, and observe whether surface of the paint film has gas
Hole is determined as criterion of acceptability with pore-free.
3.10 high temperature and pressure experiments are 5% sodium chloride solutions being soaked in the template for the state that regulates in high temperature and high pressure kettle
In, it is arranged 55 DEG C of temperature, nitrogen and carbon dioxide mix ratio are 94:6, and mixture pressure is 3 megapascal, after keeping for 24 hours,
Template is taken out, whether observation specimen surface there are the defective modes such as blistering, and complete with paint film, good is qualification determination foundation.
Four, examining report
One surface material performance test of table report
Two primer performance test of table report
Three face of table, bottom composite property test report
By the data in table it is found that the anticorrosive paint in the present invention improves the acid resistance, alkali resistance and attachment of paint film
Power, so that the overall performance of anticorrosive paint is improved.
