Description

Floating cloth on water and manufacturing method thereof

The invention relates to a manufacturing technique, in particular to a floating plastic tape and a manufacturing method thereof.

The yacht is used for recreational activities in addition to water supply. It is also an important tool for emergency rescue or transportation on the water, such as shipwrecks and floods. Especially in emergency rescue, such as when the ship is difficult, the yacht will have to withstand the violent weather and temperature changes during the rafting process and the hard objects such as reef grinding and scraping. Therefore, the tape used by the yacht must have a high degree of weather resistance. The anti-wear and high adhesion between materials can meet the needs of various practical applications.

However, the tapes produced in the current production process of the tape, such as polyvinyl chloride (PVC) and polyurethane (TPU), are mostly larger than one, and are not durable, or the hydrolysis of polyurethane occurs. Rubber is used in a longer life than other materials, so rubber is used. However, there are many types of rubber, with different reinforcing fillers, processing aids, anti-aging agents, accelerators, etc., which will give rubber a variety of different properties. Since most of the raw material formulations have a specific gravity greater than one, the choice of raw materials, added amount and cloth selection becomes an important key. To be able to float the rubber skin on the water, the specific gravity of the rubber itself and the cloth should be less than one. Only one specific gravity is less than one, and it may still sink in the water. Unless one of the specific gravity is different from the other, it is possible to float. On the water.

Accordingly, the present invention has been made in view of the above problems, and proposes a floating cloth on water and a method of manufacturing the same to solve the problems caused by the prior art.

The main object of the present invention is to provide a floating plastic tape and a manufacturing method thereof, which are designed to be a rubber compound containing a foaming agent, which is combined with a base fabric having a specific gravity of less than one to become a leather material floating on the water for use. Isolation of water and outside pollution can also be used in boats to reduce the chance of shipwrecks.

In order to achieve the above object, the present invention provides a floating plastic tape comprising one The base fabric has a specific gravity of less than one, and a rubber paste is formed on the top surface and the bottom surface of the base fabric. The other two rubber sheets have a specific gravity of less than one and include at least a foaming agent, and the two rubber sheets are respectively adhered to the top surface and the bottom surface of the base fabric through the rubber paste.

The invention also provides a method for manufacturing a floating cloth on water. Firstly, a rubber paste is applied on the top surface and the bottom surface of a base cloth, and the specific gravity of the base cloth is less than one. Next, the rubber sheet containing at least a foaming agent and a specific gravity of less than one is applied to the top surface and the bottom surface of the base fabric through the rubber paste, respectively, to complete the production.

For a better understanding and understanding of the structural features and the achievable effects of the present invention, please refer to the preferred embodiment and the detailed description.

Please refer to Figure 1. The present invention comprises a base fabric 10 having a specific gravity of less than one, such as polypropylene cloth, having a specific gravity of from 0.9 to 0.91. A rubber paste is formed on the top surface and the bottom surface of the base fabric 10, and the composition thereof comprises 8 parts by weight (PHR) of toluene, 3 parts by weight of rubber, 1 part by weight of a promoter and 1 part by weight of a hardener, wherein the accelerator a predispersion comprising a 2-thiol imidazoline and a rubber elastomer and a predispersion of tetramethylthiuram and a rubber elastomer, the hardener comprising polyisccyanate, Methylene chloride . The second rubber cloth 12 has a specific gravity of less than one, and at least comprises a foaming agent. The second rubber cloth 12 is respectively adhered to the top surface and the bottom surface of the base fabric 10 through a rubber paste, wherein the foaming agent is dinitroso-5. Methyltetramine. The foaming agent can generate gas between the rubbers, but small holes are not visible to the naked eye, so that the inside of the rubber is filled with tiny holes, and it is easier to float on the water surface. The two rubber sheets 12 are formed by feeding a rubber compound containing one of the foaming agents into a calender and rolling. The composition of the rubber compound contains 100 weights Amount of main glue, 1 to 3 parts by weight of foaming agent, 1 to 3 parts by weight of diphenylamine, 2 to 5 parts by weight of naphthenic oil, 5 to 10 parts by weight of tackifier, 20~ 30 parts by weight of carbon black and 1 to 4 parts by weight of sulfur, wherein the main rubber further comprises a natural rubber having a specific gravity of 0.91 to 0.93 and an ethylene propylene diene monomer (EPDM) having a specific gravity of 0.86 to 0.87, and the tackifier further comprises Polyisobutylene and cerium oxide. Since the invention has the structure of the rubber tape, it can be used for covering the water surface without sinking into the bottom of the water, which can be used to insulate the pollution of the water and the outside; or can be used on the boat, the leather of the general boat They will sink into the water. When a foreign object leaks, there will be a shipwreck. For example, a floating rubber can be used to make a boat. When it leaks, it can float on the water to reduce the probability of shipwreck.

The production process is described below. Please refer to both Figure 1 and Figure 2. First, as shown in step S10, a rubber paste is applied to the top and bottom surfaces of the base fabric 10. Next, as shown in step S12, the base fabric 10 is sent to an oven to be baked at 100 to 120 degrees Celsius to dry the solvent of the rubber paste. Then, as shown in step S14, the two rubber sheets 12 are attached to the top surface and the bottom surface of the base fabric 10 through the rubber paste. Finally, as shown in step S16, a vulcanization step is performed, in which the base fabric 10 and the second rubber cloth 12 are sent to a drum vulcanizer (ROTO CURE) for sulfur for 8 to 10 minutes to make the base fabric 10 and the second rubber. The cloth 12 has elasticity, the temperature is set to 140 to 160 degrees Celsius, the pressure is set to 40 to 50 kg/cm 2 , and the speed is 0.3 to 0.35 yards per minute.

In the above process, step S12 or step S16 may be omitted, or omitted at the same time, and a floating tape can also be produced. When step S12 is omitted, after step S10 is completed, step S14 is directly performed. In addition, in step S14, one of the rubber sheets 12 may be first applied to the top surface of the base fabric 10 through a rubber paste, and the rubber cloth 12 on the top surface is placed on the nylon cloth cover 14. Then, another rubber cloth 12 is applied to the bottom surface of the base fabric 10 through a rubber paste, and the rubber cloth 12 on the bottom surface is also covered with a nylon cloth cloth 14, as shown in Fig. 3. Finally, step S16 is performed.

Please continue to refer to Figure 4, the following describes the production process of rubber cloth. First, as shown in step S18, the rubber compound is first mixed by a 10,000 horsepower mixer. Next, as shown in step S20, the rubber compound is mixed by two rollers in an environment of 80 to 100 degrees Celsius, and the roller includes a coarse wheel and a thin wheel. Finally, as shown in step S22, the rubber compound is fed into the calender to form a second rubber cloth 12.

In summary, the floating tape made by the invention not only can isolate the pollution of water and the outside, but also can be applied to the ship, and can also reduce the probability of shipwreck.

The above is only a preferred embodiment of the present invention and is not intended to be limiting. The scope of the present invention is intended to be included within the scope of the invention as defined by the appended claims.
