(88) S4, Impregnation latex impregnation: After impregnation with the coagulating agent for 60 s, back, top, front, and bottom sides of a coagulating agent-impregnated glove core were impregnated with the impregnation latex.

(89) S5, Spinning: after impregnation with the impregnation latex, spinning was conducted for 50 s.

(90) S6. Surface treatment: An industrial salt was sprayed with a fan frequency of 30 Hz to form a latex coating.

(91) S7. Pre-vulcanization and high-temperature vulcanization: Pre-vulcanization was conducted at 90 C. for 1.5 h, and high-temperature vulcanization was conducted at 110 C. for 1.5 h.

(94) The glove prepared in Examples 1 to 9 and Comparative Example 1 each were subjected to mechanical testing analysis. Specific test results are shown in Table 1 below:

(95) TABLE-US-00001 TABLE 1 Mechanical testing results for Examples 1 to 9 and Comparative Example 1 anti-slip Tear Puncture performance Wear resistance resistance resistance Comparative (2.3) LL (8100 r) grade 4 Grade 3 Grade 1 Example 1 Example 1 (2.5) LL (8300 r) grade 4 Grade 3 Grade 1 Example 2 (2.6) LL (15000 r) grade 4 Grade 3 Grade 1 Example 3 (2.7) LL (17000 r) grade 4 Grade 3 Grade 1 Example 4 (2.9) LL (22000 r) grade 4 Grade 3 Grade 1 Example 5 (3.0) LL (22000 r) grade 4 Grade 3 Grade 1 Example 6 (3.0) LL (25000 r) grade 4 Grade 3 Grade 1 Example 7 (3.0) LL (24000 r) grade 4 Grade 3 Grade 1 Example 8 (3.0) LL (24000 r) grade 4 Grade 3 Grade 1 Example 9 (3.0) LL (28000 r) grade 4 Grade 3 Grade 1

(96) It can be seen from the above experimental data that the preparation method provided by the present disclosure can effectively prepare a coating with high anti-slip performance and high wear resistance. It can be seen from the above data that the more uniform the sprayed bio-based organic polymer material, the better the anti-slip performance and wear resistance of the glove. In addition, when a fan frequency is 20 Hz, the performance of a coating formed by spraying the bio-based organic polymer material completely exceeds the performance of a coating formed by spraying the industrial salt.

(97) It can be seen from the FIGURE that the coating prepared by the preparation method of the present disclosure has a relatively uniform pore size, and uniform bubble pores in the coating like suckers. When the rubber is in contact with a surface of an object, the rubber can allow an adsorption effect through large-area attachment to tiny protrusions on the surface of the object to form a vacuum space under an action of an atmospheric pressure, such that the suckers are closely attached to the object, which greatly improves a suction force and thus increases a grasping force of a coating. In addition, the biological compound enzyme in the formula system of the present disclosure can decompose the excess bio-based organic polymer material on a coating during a production process, such that only a high-strength film layer is retained on a surface of the coating to significantly improve the wear resistance of the coating.

(98) The above are merely preferred examples of the present disclosure, but are not intended to limit the present disclosure.
