Description

Technical Field

[0001] The utility model relates to the technical field of protective clothing, in particular to a water pressure impact resistant suit. Background Technique

[0002] After years of navigation, a thick layer of scale will form on the hull outer shell below the waterline of large ships. These scales are composed of algae and shellfish attachments, which are tight and hard. On the other hand, after years of operation, large ships will inevitably have large areas of rust. Therefore, when repairing large ships, it is generally required to remove the coatings, scale, old paint and rust on the hull, and then apply new paint to ensure the normal navigation of the ship and extend its service life.

[0003] At present, the shipbuilding industry uses high-pressure water jet technology. By using a high-pressure water pump, the pressure of ordinary water is increased to 40 - 250 MPa, and the single-gun flow rate is about 20 - 39 L / min. It is ejected from the nozzle of the high-pressure water gun to form an ultra-high-pressure water jet or abrasive water jet. By using the powerful impact force of the water jet, the coatings, scale, old paint and rust can be quickly removed. However, in the actual working process, if the high-pressure water gun fails, the high-pressure water flow will spray towards the operator, causing harm to the operator. Therefore, in order to play a protective role, it is necessary to develop a water pressure impact resistant suit. Content of the Utility Model

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Combined with Figures 1-4 A detailed description of this embodiment is given. An anti-water-pressure impact suit includes: an upper garment and trousers; both the upper garment and the trousers are made of anti-water-pressure impact fabric; the anti-water-pressure impact fabric includes an outer layer 1, an intermediate layer 2 and an inner layer 3; the outer layer 1 is a waterproof polyester woven fabric; the intermediate layer 2 is knitted from high-strength core-spun yarn; the core yarn of the high-strength core-spun yarn is ultra-high molecular weight polyethylene fiber filament, and the wrapping yarn is polyester fiber filament, and the wrapping yarn is helically wound around the outside of the core yarn; the inner layer 3 is woven from polyester fiber filaments.

[0020] Specifically, the thicknesses of the outer layer 1, the intermediate layer 2 and the inner layer 3 are all 1 mm, and they are connected by sewing.

[0021] Specifically, the waterproof polyester woven fabric is a polyester woven fabric finished with an organosilicon-modified polyacrylate fluorine-free waterproofing agent. Specifically, the preparation process of the organosilicon-modified polyacrylate fluorine-free waterproofing agent is as follows: Weigh appropriate amounts of octadecyl acrylate, isobornyl methacrylate, self-made reactive silicone oil, and N-hydroxymethyl acrylamide in a beaker. Using appropriate amounts of dimethyloctadecylamine, XP-50, and AEO-20 as emulsifiers, add appropriate amounts of glacial acetic acid and deionized water, and use ultrasonic emulsification and dispersion for 15 minutes under stirring conditions. After sufficient emulsification, a stable pre-emulsion is formed. Transfer the pre-emulsion to a high-pressure reaction kettle. After using nitrogen to displace the air in the high-pressure kettle, add 2,2-azobis(2-amidinopropane) dihydrochloride accounting for 0.5% of the total mass of the monomers as an initiator, press in vinyl chloride, heat in a water bath to 62 °C, keep warm for 5 hours, and then cool and discharge. The waterproof finishing process of the polyester woven fabric is: one dip and one nip (nip ratio 50%-70%), baking temperature 130-170 °C, baking time 30-180 s, and place for moisture regain (moisture regain conditions: relative humidity 65% ± 2%, temperature (20 ± 2) °C, moisture regain for 24 h).

[0022] Further, the grammage of the outer layer 1 is 300-400 g / ㎡, and the grammage of the intermediate layer 2 is 435-450 g / ㎡.

[0023] Further, the fineness of the ultra-high molecular weight polyethylene fiber filament is 400 D. The ultra-high molecular weight polyethylene fiber is the chemical fiber with the highest strength. Its main chain is a highly symmetric methylene structure. The theoretical breaking strength is as high as 328 cN / dtex. The actual breaking strength of mainstream products is between 30-50 cN / dtex, and the initial modulus is greater than 900 cN / dtex. It is a high-strength and high-modulus fiber, and its density is only 0.97 g / cm 3 , lower than most synthetic fibers, and it has good chemical stability, impact resistance, and cutting resistance.

[0024] Further, the wrapped yarn includes two polyester fiber filaments, which are cross-wound around the outside of the core yarn in opposite directions. The two polyester fiber filaments form a net-like cross-wrapping structure outside the core yarn, greatly enhancing the structural stability of the yarn. The unique net-like structure can not only enhance the overall strength of the high-strength core-spun yarn but also effectively slow down the wear of the core yarn caused by external frictional forces.

[0025] Further, both the upper garment and the trousers are provided with a reflective strip 4. The reflective strip 4 can reflect the surrounding light at night, thus playing a certain warning role for passers-by and drivers.

[0026] Further, the back of the upper garment is provided with a magic tape 5. When wearing the upper garment, put the arm into the sleeve, and then stick the magic tape 5 on the back.

[0027] Further, the pants are provided with braces 6 and a waistband 7. The braces 6 and the waistband can be adjusted according to the needs of the wearer to adapt to the body shape of the wearer.

[0028] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
