In a first aspect, the invention provides a preparation method of a silica gel material for protective clothing, which comprises the following steps:

S1X-ray film

The screen printing plate is formed by making a plate through an X-ray emitting sheet and silica gel, the printing pattern of the screen printing plate is a pattern which is in accordance with anatomical displacement according to different parts of a human body and is approximately the same as the pasting line of a moving adhesive tape when in use, and the specific figure is shown in figures 1-7. In order to meet the requirements of different statures, the clothes are divided into different sizes such as S size, L size, XL size and the like, and the corresponding patterns of the clothes with different sizes are slightly different in size and are designed in a targeted manner.

In particular, the overall process of X-ray imaging is known in the art, and the inventors have developed patterns that conform to anatomical misalignments. The process of X-ray film includes: the adhesive film is applied to the printed side of the screen to form an anatomically correct pattern, and then exposed, washed and dried.

In the actual operation process, different X-ray emitting sheets are formed aiming at different human body parts, a pasting film (such as a film medicine film) is pasted on the screen printing surface to form a special walking position, then the special walking position is exposed in a vacuum exposure machine, and the exposure time is according to the thickness of photosensitive glue, the energy of an exposure lamp and the requirements of a manufactured screen printing plate.

Furthermore, the water washing is to wet two surfaces of the silk screen (about 30-60 s) by water with the temperature of 20-30 ℃, and then wash by a high-pressure water gun until the image is displayed. The drying process is to suck the water and then dry the mixture at the temperature of 30-40 ℃.

The method is characterized in that the exposed silk screen is soaked by water for about 1 minute on two sides and is flushed by high-pressure water until the silk screen is completely clear; comparing under lamplight, and judging whether the plate is completely clear or not and whether the plate making is successful or not, and if not, redoing; after drying the wet net, placing under a lamp box, and using net sealing slurry to repair the defects of sand holes, burrs and the like.

S2 silica gel platemaking

Comparative example 1

The only difference from example 1 is: the ingredients in the step (3) are different, and the difference is only that: 20 parts of organic germanium is added.

The results show that the formulation in this comparative example is not reasonable, ultimately resulting in a liquid silica gel that does not solidify.

Comparative example 2

The only difference from example 1 is: the ingredients in the step (3) are different, and the difference is only that: the liquid silicone rubber is replaced by silicone rubber.

The results show that the product obtained in this comparative example is less sensitive to skin, less stressful and more easily breakable than the product obtained in example 1, in accordance with GB/T1681-.

Comparative example 3

The only difference from example 1 is: the ingredients in the step (3) are different, and the difference is only that: the liquid silica gel is replaced by the mucilage.

The results show that the product obtained in this comparative example has a lower tension and is more susceptible to breakage, tearing and the implementation of the standard GB/T1681-.

Test example 1

The protective effect and the anti-fatigue effect of the sports protective knee joint sleeve are tested, and the results are shown in tables 1 to 9.

(1) The muscle strength is improved after wearing the kneepad, and compared with wearing the kneepad before experiments, the muscle strength after wearing the kneepad is higher as shown in table 1, and the kneepad can be related to the comfortable back muscle of the tights and is more convenient to exert force.

TABLE 1 test results of mean work of isokinetic muscle force (W)240 °/s

The muscle strength decline speed is slowed down after wearing the tights, and isokinetic muscle strength test results before and after the experiment show: before tights fatigue > before normal training clothes fatigue > after tights fatigue > after normal training clothes fatigue, as shown in table 2.

There are: (the muscle strength before fatigue of the tight-the muscle strength after fatigue of the tight) < (the muscle strength before fatigue of the normal training clothes-the muscle strength after fatigue of the normal training clothes). The tights are proved to have certain effect of delaying the reduction of muscle strength. Wherein, the endurance test is more obvious. The effect of the series products is better for delaying the decline of the strength of endurance exercise.

TABLE 2 test results of mean work of isokinetic muscle force (W)240 °/s

(2) And (3) testing the anti-fatigue effect, and specifically, see tables 3-4.

Median Frequency (MF) representation of surface electromyography results: before the tights fatigue > before the fatigue of normal training clothes > after the tights fatigue > after the normal training clothes is tired, the phenomenon is comparatively obvious. It is shown that root mean square amplitude (RMS) also shows a similar phenomenon, but is not obvious. The RMS and MF results were consistent with the phenomena exhibited by muscle strength testing, suggesting that: the tights have certain anti-fatigue effect.

TABLE 3 Knee Joint test results

TABLE 4 elbow test results

(3) The lower limb stability test results are shown in table 5.

It is thus clear that protective equipment knee joint stability in this application promotes the effect better, and elbow joint stability promotes the effect also better, similar with the knee joint.

TABLE 5 Knee Joint stability test results

(4) Biochemical indicators were tested as shown in tables 6-8. The endurance fatigue result in blood lactic acid is obvious, and the strength and incremental load test is not obvious. The result accords with the blood lactic acid rule, and the tights have certain anti-fatigue effect on endurance projects.

TABLE 6 blood lactic acid test results (mmol/L)

TABLE 7 haematurin test results (mg/dL)

TABLE 8 creatine kinase test results (U/L)

In the biochemical index effect, the blood lactic acid index is obvious, and the effect of relieving fatigue can be reflected. But creatine kinase and haematurin were temporarily not evident. This may be associated with too many test contents being measured simultaneously, resulting in poor performance of the subject's movements. To further investigate the effects of creatine kinase and haematurin, measurements in an outdoor playground without wearing surface myoelectricity were considered.

The endurance fatigue result in blood lactic acid is obvious, and the strength and incremental load test is not obvious. The results are consistent with the blood lactic acid rule. The Pabo blessing tights have certain anti-fatigue effect on endurance projects.

Test example 2

The protective effect of the product obtained in the test examples is shown in tables 9 to 11.

TABLE 9 knee joint enhancement compared to unworn conditions

TABLE 10 enhanced effect of elbow joint compared to unworn condition
