Test case 1
The right performance of the electric heating obtained embodiment 1-7 and comparative example 1-3 is tested, and wherein anti-flammability, high temperature dimensional stability, thermal resistance value are tested thermal insulation layer or the part that plays thermal insulation layer effect, and test result is in table 1.
The performance test results that the electric heating that table 1 embodiment 1-7 and comparative example 1-3 obtains is right
Be described as follows about method of testing and test result:
1, gum sprayed cotton thermal insulation layer has good resistance to elevated temperatures.Once circuit or temperature control component break down, heater element is constantly heated, the PSA fiber water of heater element and outsourcing thorn felt and gum sprayed cotton temperature are constantly raised, and the heat resistance that the fibers such as PSA fiber are good avoids the contraction distortion of spunlace non-woven precoat 4 and gum sprayed cotton thermal insulation layer 2.They can represent by the dimensional stability of material under high temperature and shrinkage factor resistance to elevated temperatures, test by following method of testing.
High temperature dimensional stability: carry out damping by GB/T 6529 specified standard atmospheric conditions to sample, sample is cut into 10cm × 10cm, marks horizontal and vertical, measures physical length lateral length M
1, longitudinal length M
2.After putting into 200 DEG C of continuous drying 30min of baking oven, take out, again measure sample and indulge lateral length, lateral length N
1, longitudinal length N
2, calculate lateral shrinkage S1, longitudinal contraction rate S2 respectively:
Lateral shrinkage S
1=(M
1-N
1)/M
1× 100%
Longitudinal contraction rate S
2=(M
2-N

2× 100%
The meiting powder that common electric blanket uses at 250 DEG C can rapid desufflation melting felting together.
In the embodiment of the present invention, product is at 200 DEG C, under 30min process, and good stability of the dimension, shrinkage factor≤5%, preferably≤3%, most preferably≤1%.
2, thermal insulation layer 2 and spunlace non-woven precoat 4 have good fire resistance.
Combustibility method of testing: GB/T 5455-1997, lights under the sample of 30cm × 8cm being placed on the burner of regulation, and after burning time 12s determined by measuring gage, the after flame time t of sample, glow time T and char length L.
After flame time is 0, and the time of glowing is 0, char length≤120mm, preferably≤80mm, most preferably≤60mm
3, there is good electrical insulation capability
Thermal insulation layer 2 and spunlace non-woven precoat 4 also play good electric insulation effect, once electric blanket improper use or collect improper, make heater element outsourcing insulating materials damaged, the refractory fibrous material that thermal insulation layer uses, because have good electrical insulating property, can avoid human electric shock.
Electrical insulating property dielectric constant represents, dielectric constant is less, the good insulating of illustrative material.
The method of testing of dielectric constant: with the cylinder copper coin formation plate-heater that two 1mm are thick, upper board diameter is 76mm, and lower board diameter is 100mm, access universal bridge.By needing the material of test to put in the middle of two electrode plate, measure its capacitance.
The computing formula of dielectric constant is: dielectric constant=14.38 × C × H ÷ D
2;
C: the capacitance of mensuration;
H: after thermal insulation layer puts into two electrodes, distance cotton inside two cube electrodes;
D: the diameter of upper garden battery lead plate;
As shown in structure chart, because of the spunlace non-woven precoat 4 having high temperature resistant inherent fire-retardant fiber to make in the middle of human body and heater element, and thermal insulation layer 2, when the insulating properties of therefore testing, be that the spunlace non-woven precoat 4 of each scheme and thermal insulation layer 2 are divided the test that is superimposed together.
4, good thermal property
PSA fiber heat-insulation blanket has good thermal property, even if in cold situation, polysulphonamide fiber soft fluffy, also can use as heat-insulation warm keeping mattress.Or in order to safety before heating sleep, broken by electricity, prevention heat outwardly transmits by PSA fiber nonwoven thermal insulating pad energy excellent thermal insulation performance, avoid scattering and disappearing of heat.
Thermal property can utilize thermal resistance value to represent, thermal resistance value is higher, and the heat-insulating property of illustrative material is better.
The method of testing of thermal resistance value: according to GB/T11048-2008, is cut into the square of 500mm × 500mm by sample, the static flat band method specified in employing standard is tested, and records the thermal resistance value R of sample
ct(unit: m
2.W/K).
5, excellent thermal protective performance
Material TPP value testing standard: NFPA 2112 fire retardant protective clothing testing standard, TPP thermal protective performance tester
It is 2cal/ (cm that the cloth of a piece 6 square inches is positioned over total energy density
2× s) thermal convection current and radiant heat source under, then record time of reaching needed for second degree burns, TPP value (TTP valve) time of being is multiplied by cal/ (cm
2× s) numerical value.
The present invention's test be the TPP value of electric blanket entirety.
