Test of

Test 1

The inflatable cold-resistant children raincoat prepared according to the embodiments comprehensively compares the performances in all aspects:

wherein (1) the tensile rebound effect test is as follows: strips with the size of 10cm long and 2cm wide are respectively cut from the same position of the raincoat body prepared in each example to be used as samples, a universal testing machine is respectively used for carrying out bidirectional tensile test, the force gradient is 10N, 20N, 30N, 40N and 50N, the time is 10S, the raincoat body is horizontally placed for 10S, the tensile rebound effect and the deformation quantity are observed and recorded, the deformation quantity is = (L-L0)/L0 100%, wherein L is the length of the horizontally placed 10S, and L0 is the initial length of 10cm, and the specific values are shown in Table 1;

(2) the aging experiment is divided into a specific method for resisting damp-heat aging: damp-heat aging resistance was performed according to method C of FZ/T01008-2008, and the inflatable cold-resistant raincoat for children prepared in each of examples 1-11 was prepared by randomly cutting a sample of 100 cm2 glass 1 cm2, preheating the oven to 70 ℃. + -. 1 ℃ and a relative humidity of at least 95%, placing the sample in the oven without the sample being under tension, exposing both sides of the sample to hot air, observing the condition of the sample after 7 days, 14 days, 21 days, 28 days while ensuring that the pressure in the oven does not exceed the atmospheric pressure, repeating the experiment three times or more to eliminate the experimental contingency, and comparing the differences of each example according to the breakage rate; the following table 2 specifically shows;

TABLE 1

TABLE 2

According to the experimental data of the above tables 1 and 2, the comparison results:

(1) the raincoat prepared by each embodiment is nontoxic and does not contain heavy metal, and meets the environmental protection standard; in the examples 1, 2 and 3, the performance indexes in all aspects are relatively balanced, and the best performance index is especially the best performance index in the example 1;

(2) in example 4, although the artificial accelerated aging test is excellent, the tensile rebound effect is poor due to the small addition amount of the flexible main body material of the raincoat; example 5 is the opposite; example 6 because the addition amount of each component in the formula of the flexible main body material of the raincoat is small, the experimental result is similar to that of example 4, and example 7 is just the opposite, although the tensile rebound effect is good, the anti-human accelerated aging is poor, and the durability of the raincoat is general;

(3) examples 8 to 11 are directed at comparison of the detachable cold-resistant lining of the raincoat, compared with example 1, examples 8 and 10 have poor cold-resistant effect due to the fact that the modified polyester or the formula components are added in small amount; examples 9 and 11 are in contrast strong against cold but poor against accelerated human aging.
