[0001] The present invention relates to the technical field of diving fabrics, and more specifically, to a diving fabric with an embedded pattern and a preparation method thereof. Background Art

[0002] Diving fabric is a synthetic rubber foam, namely foamed chloroprene rubber. Neoprene has high tensile strength and excellent resistance to aging, heat, oil and chemical corrosion, and is mostly used in diving suit fabrics.

[0003] At present, the common diving suits on the market are usually printed with patterns and designs for the sake of beauty and visual difference. Since the main component of diving suit fabric is chloroprene rubber, printing materials such as ink are not easy to penetrate into the diving suit fabric, and patterns cannot be printed directly on the diving suit fabric. Usually, the patterns need to be printed on the textile fabric first. ， The patterned fabric is then bonded to the diving suit fabric. The pattern printed on the diving suit in this way is easily corroded and falls off after being exposed to the seawater environment, and the pattern will be stretched and deformed during wearing, which affects the appearance and is not durable. Summary of the invention

[0009] Preferably, in step (3), the pattern is printed on the upper surface of the foamed chloroprene rubber sponge sheet by direct inkjet printing.

[0010] Preferably, in step (2), the glue is set to be water-based glue.

[0011] Preferably, in step (3), the second glue is configured as an aqueous glue containing an aerogel component.

[0013] Preferably, the water absorption rate of the foamed chloroprene rubber sponge sheet after compression is 14.44%.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The structural design of the present invention is reasonable. A compressed foamed chloroprene rubber sponge sheet is used as a substrate. The compressed sponge sheet has a larger apparent density, a tighter internal molecular structure, and a smoother surface. Printing materials such as ink can better penetrate into the surface of the sponge sheet, so that the pattern and the sponge sheet are integrated together.

While being environmentally friendly, it can better present the pattern and extend the service life of the pattern.

[0020] 2. The present invention sprays a titanium coating on the surface of the pattern, which can make the pattern more resistant to oxidation and friction, better protect the pattern printed on the sponge sheet, increase the corrosion resistance and wear resistance of the pattern in the seawater environment, extend the service life of the pattern, and improve the aesthetics of the pattern.

[0022] 4. The tear resistance and durability of the diving fabric made of compressed sponge sheets are also improved to a certain extent. The water absorption rate of the compressed sponge sheets is 14.4%, which greatly reduces the water absorption rate of the diving suit fabric, improves the thermal insulation effect of the diving suit and reduces the weight of the diving suit in the use environment, better protecting the safety of divers.

[0023] 5. The glue used in the titanium coating of the present invention contains aerogel components.

[0029] The preparation method of the diving fabric with embedded patterns comprises the following steps:

[0030] (1) placing a 5-7 mm (preferably 6 mm) thick foamed chloroprene rubber sponge sheet 1 into a crawler-type sponge sheet compression machine, adjusting the temperature of the crawler-type sponge sheet compression machine to 210-230 degrees Celsius, and setting the pressure to 45-55 N (preferably 50 N) per square centimeter, the crawler gap to 1-2 mm (preferably 1.5 mm), and the crawler speed to 1.5-3 meters per minute, and performing cyclic rolling compression on the foamed chloroprene rubber sponge sheet 1, and then passing through a linked cooling zone of 0-5 degrees Celsius to be shaped, and the thickness of the sponge sheet after cooling is 2-4 mm (preferably 3 mm);

[0031] The uncompressed sponge sheet and the compressed sponge sheet were compared by test. The apparent density of the uncompressed sponge sheet is 171.4kg / m 3 The apparent density of the compressed sponge sheet is 239.0kg / m 3 The test method is GB / T 6343-2009. The tear strength of the uncompressed sponge sheet is 26N / cm, and the tear strength of the compressed sponge sheet is 29N / cm. The water absorption rate of the uncompressed sponge sheet is 42.01%, and the water absorption rate of the compressed sponge sheet is 14.44%.

[0032] The compressed sponge sheet has a higher apparent density, a tighter molecular structure inside the sponge sheet, and a smoother surface. Ink and other printing materials can better penetrate into the surface of the sponge sheet, so that the pattern and the sponge sheet are integrated together, increasing the service life of the pattern. The tear resistance and durability of the diving suit made of this sponge sheet are also improved to a certain extent.

[0033] The water absorption rate of the compressed sponge sheet is 14.4%, which greatly reduces the water absorption rate of the diving suit fabric, improves the thermal insulation effect of the diving suit and reduces the weight of the diving suit in the use environment, and better protects the safety of divers.

[0034] (2) laying the foamed chloroprene rubber sponge sheet 1 treated in step (1) flat on a workbench, spraying graphene powder evenly on the lower surface of the foamed chloroprene rubber sponge sheet 1, using glue to firmly adhere the graphene powder to the lower surface of the foamed chloroprene rubber sponge sheet 1 to form a graphene coating 2, and evenly attaching a patch 3 to the lower surface of the graphene coating 2;

[0035] In this embodiment, the graphene coating comprises graphene powder and glue 1, and the graphene powder has the functions of fast heating, uniform heating, heat accumulation and warming, and far-infrared sterilization.

[0036] (3) A pattern is spray-printed on the upper surface of the foamed chloroprene rubber sponge sheet 1 to form a pattern layer 4, and then titanium powder is evenly sprayed on the upper surface of the pattern layer 4, and glue 2 is used to firmly bond the titanium powder to the upper surface of the pattern layer 4 to form a titanium coating 5.

[0037] In step (3), the pattern can be printed on the upper surface of the foamed chloroprene rubber sponge sheet 1 by direct inkjet printing, which can better integrate the ink and the sponge sheet.

[0038] The titanium coating can make the pattern more resistant to oxidation and friction, can better protect the pattern printed on the sponge sheet, increase the corrosion resistance and wear resistance of the pattern in the seawater environment, extend the service life of the pattern, and improve the aesthetics of the pattern.
