The test of 20 flame retardant property of embodiment
The fire-retardant flaking obtained to the surface embodiment 2-19 sprinkling retardant solution is tested, and test content includes following
Three aspects, test result are as shown in table 3.
1, the fire retardant sprinkling uniformity and coverage rate of fire-retardant flaking
(1) fire-retardant flaking is distinguished using in such a way that red staining agent is added in fire retardant storage tank, red staining agent
Additive amount is that 1 kilogram of coloring agent is added in every cubic metre of retardant solution, and the storage of fire retardant in storage tank is controlled before detecting, is guaranteed
The storage of fire retardant is about 10 minutes usage amounts.
(2) it is repeatedly sampled at the inspection door below spiral extruder, sampling interval time is 3-4 minutes, every sub-sampling
Flaking quantity is 50, it is desirable that flaking area is greater than standard flaking (standard flaking size: 120mm piece area is greater than) area
40%.
(3) uniformity detects: the fire retardant coverage condition on each flaking is observed by flaking surface color, when flaking face
When the surface area of the variant part of color is greater than the 30% of entire flaking total surface area, judge that flaking sprinkling uniformity is unqualified.
Uniformity is stated with uniformity qualification flaking Zhan total flaking percentage:
Uniformity=(uniformity qualification flaking quantity/flaking total quantity) × 100%.
(4) coverage rate: observing the fire retardant coverage condition on each flaking by flaking surface color, when flaking not by
When the area of coloured portions is greater than the 10% of entire flaking total surface area, judge that flaking sprinkling covering is unqualified.
Spreadability makes a decision result with coverage rate:
Coverage rate=(covering qualified flaking quantity/flaking total quantity) × 100%.
2, amount of flame-retardant agent
Front and back flaking water-cut variation, which is sprayed, by detection calculates amount of flame-retardant agent.
(1) flame retardant concentration detects: taking 50g or so retardant solution on production line, 2g drop is taken from 50g retardant solution
Enter surface plate, is put into 50 surface DEG C baking ovens and dries 2 hours, calculate solid content.Fire retardant solid content is denoted as a.
(2) fire retardant flaking measurement of water-content coefficient is not sprayed: repeatedly sampling respectively nearby, interval 30 before carrying out the process
Second, point 3 sub-samplings are uniformly mixed.10 flakings are randomly selected from the flaking of mixing, and (area is not less than standard flaking area
40%) it, is put into fast tester for water content, in the case where 100 enter fast DEG C, 10 minutes, moisture content is measured, is denoted as moisture content b.
(3) fire-retardant flaking measurement of water-content coefficient: sampling at the inspection door below spiral extruder, is spaced 30 seconds, divides 3 times and takes
Sample is uniformly mixed.10 flakings (40% of area not less than standard flaking area) is randomly selected from the flaking of mixing, is put into
Fast tester for water content measures moisture content in the case where 100 enter fast DEG C, 10 minutes, and moisture content is denoted as c.
(4) fire retardant adhesion amount (refers to that the sprayed weight for being attached to flaking of fire retardant accounts for the weight percent of over dry flaking
Than) calculate:
Calculation formula x=(c-b) × a/ ((1-b) × (1-a-c)) × 100%.
3, the flame retardant effect detection of fire-retardant flaking
Detection method:
(1) fire-retardant flaking is dried 10 minutes in 100 ± 2 DEG C of baking ovens, is then placed on alcolhol burner and burns, visually judges flaking
It is ignited the required time, is denoted as duration of fire resistance.According to whether the duration of fire resistance for reaching the requirement of this step judges that the flaking is
The no flame retardant effect for reaching the step.
(1) it samples, is spaced 30 seconds at the inspection door below spiral extruder, point 3 sub-samplings are uniformly mixed.From mixing
Flaking in randomly select 50 flakings the 40% of standard flaking area (area be not less than).
(2) flaking is put into 100 ± 2 DEG C of baking oven layings uniform, no superposition, dries 10 minutes.
(3) in calm show window, alcolhol burner is lighted, one jiao that fire-retardant flaking is vertically clamped with fixture is placed on alcolhol burner
Side, the minimum angle of flaking is located at alcolhol burner flame envelope center.Observe flaking combustion case, the time that record flaking is ignited, Yi Jiyi
After flame time and smoldering time after opening alcolhol burner.
The acceptability criteria of flaking anti-flammability is as shown in table 2.
Table 2.
Anti-flammability makes a decision result with fire-retardant qualification rate:
Fire-retardant qualification rate=(flaking quantity/flaking total quantity of anti-flammability qualification) × 100%.
Table 3
By above-mentioned experimental result it is found that the device of the invention and technique can significantly improve the fire retardant adhered on wet flaking
Content then improves flame retardant property.Also, the adhesion amount of fire retardant can be as needed, passes through pump discharge and retardant solution
