Description

Technical Field

[0001] This invention relates to the technical field of oil containment booms, specifically to a rubber compound, rubber sheet, low-temperature resistant oil containment boom, and its preparation method. Background Technology

[0002] During extremely cold winters, water surfaces freeze over extensively, forming thick ice layers. Since sewage pipe outlets are typically located beneath this ice, in the event of an oil spill, the leaked oil becomes trapped at the bottom of the ice and cannot be collected. This oil then flows downstream with the water, causing severe ecological pollution and significant impacts. Therefore, oil booms are necessary.

[0003] Currently, commonly used oil booms on the market are generally made of oil-resistant rubber. However, at extremely low temperatures, the rubber layer of the oil boom hardens into a leather-like state and loses its elasticity. This not only makes deployment difficult but also significantly reduces its oil-blocking effect during use, failing to meet user requirements. In this application area, there are currently no products on the market that satisfy customers. In response to the demands of our company's numerous domestic and international customers and based on the current market situation, the applicant has conducted in-depth research and development on oil boom technology, resulting in this invention. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a rubber compound, a rubber sheet, a low-temperature resistant oil containment boom, and a method for preparing the same, wherein the low-temperature resistant oil containment boom has good oil resistance and excellent cold resistance.

[0005] The technical solution adopted is as follows:

[0015] 3-7 parts of silane coupling agent

[0016] Mixed accelerator 10-14 parts,

[0017] Rubber antioxidant 1-4 parts.

[0026] 60 parts of filler

[0027] 4 parts of silane coupling agent

[0028] Mixed accelerator 12 parts,

[0029] Two parts of rubber antioxidant.

[0030] The aforementioned nitrile rubber is nitrile rubber. Cis-butadiene rubber is cis-butadiene rubber. Polyisoprene rubber is an organic compound composed of cis-1,4-polyisoprene. Rubber antioxidants include, but are not limited to, one or two of, rubber antioxidants DNP and MB, etc. Chlorinated polyethylene rubber can be low Mooney chlorinated polyethylene rubber, such as CM352L low Mooney chlorinated polyethylene rubber.

[0035] Sulfur 4-7 parts,

[0036] 12-18 parts of rubber accelerator,

[0037] Split the powder into 3-7 portions.

[0038] 4-8 parts of silane coupling agent

[0040] 1-2 parts of polymer structure modifier.

[0041] Further, the mixing accelerator comprises, by weight, the following components:

[0042] Bis-25 peroxide 100 parts

[0048] 5 parts of silane coupling agent

[0050] 1.5 parts of polymer structure modifier.

[0051] Among them, peroxide bis-25 is the vulcanizing agent bis-25, which is 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, abbreviated as AD. The bridging agent VA-7 is the vulcanizing agent VA-7 (Vulcanizator VA-7). The bridging agent, also known as a vulcanizing agent, causes the linear rubber molecular chains to cross-link, forming a three-dimensional network structure, reducing plasticity and increasing elasticity and strength. The vulcanizing agent DTDM is 4,4'-dimorpholine disulfide. The rubber accelerator can be rubber accelerator CZ, which is N-cyclohexyl-2-benzothiazole sulfenamide. The separating powder can be separating powder BX, which is commercially available. The silane coupling agent can be the commercially available silane coupling agent KBM-903; the polymer structure modifier includes, but is not limited to, ETE, which is ethyl tetrahydrofurfuryl ether.

[0052] Furthermore, the mixing accelerator is prepared by the following method:

[0053] S1. The solid components in the mixing accelerator are mixed in proportion and ground into a powder material with nanoscale fineness using a high-speed grinder;

[0054] S2. Mix the ground solid powder with other liquid components in the formula, load it into a ball mill, and ball mill for 48 hours to make a uniform paste mixture;

[0055] S3. Place the paste mixture into a mixer and stir at 90-95℃ for 8-10 hours to allow various physical and chemical reactions to occur, ultimately producing a homogeneous and stable mixture;

[0056] S4. The mixture prepared in S3 is stored at 70-80℃ for 36-48 hours for maturation treatment before use;

[0057] S5. Add 8-12 parts of calcium carbonate and 12-16 parts of thickening resin to the mixture after storing S4, put it into a mixer, and mix it into a slightly moist powder.

[0058] S6. Use a granulator to granulate the mixed powder to produce a granular mixing accelerator.

[0059] Furthermore, the filler is one or both of carbon black and calcium carbonate. Carbon black includes, but is not limited to, for example, carbon black N330.

[0060] A method for preparing a rubber compound according to the present invention includes the following steps:

[0061] Weigh out all components according to the formula ratio, add them to a mixing mill, mix at 90-120℃ for 15-30 minutes, and store the mixed rubber compound for 35-40 hours before use.

[0062] The present invention provides an adhesive tape, characterized in that it is made of the adhesive material described in the above-described scheme.

[0063] The present invention provides a method for preparing adhesive tape, which includes the following steps:

[0064] After the rubber compound described in the above scheme is hot-mixed in an internal mixer, it is then laminated with EP canvas using a calender to produce rubberized fabric.

[0065] The present invention provides a low-temperature resistant oil containment boom, which includes the adhesive tape described in the above-described scheme.

[0066] The present invention provides a method for preparing a low-temperature resistant oil containment boom, comprising the following steps:

[0067] S1. The pressed adhesive tape and film described in the above scheme are processed into oil boom semi-finished products on a molding machine according to process requirements;

[0068] S2. The formed semi-finished product is rolled by a two-roll calender to eliminate air bubbles in the fabric layer and form a belt;

[0069] S3. The rolled belt is stretched and shaped on a traction machine and then coiled for later use;

[0070] S4. Adjust the temperature, pressure, and speed of the drum vulcanizing machine to meet the threshold requirements specified in the process. After the drum reaches the set process parameters, introduce the belt into the drum and start vulcanization.

[0071] S5. Assemble the vulcanized belt and accessories together to form a complete low-temperature resistant oil containment boom product.

[0072] The low-temperature resistant oil boom is a new type of oil spill containment product developed by the applicant for environmental protection. It is inserted into pre-drilled gaps in the ice layer to effectively contain the oil between the ice and the water surface. The rubber sheet of this oil boom is made of a composite of high-strength, oil-resistant, and cold-resistant rubber and EP canvas, and it has a performance that can withstand temperatures from -60℃ to -70℃. This is a property not found in ordinary oil booms.

[0073] The structural components of this low-temperature resistant oil containment boom include: a belt (a belt made of rubber sheet, serving as the main body of cold-resistant rubber), support rods, support components, buffer airbags, and clamps.

[0074] This low-temperature resistant oil boom is installed through pre-drilled gaps in the ice. The lower part of the boom extends into the water, while the upper part is connected to the gaps via several support components. This way, oil at the bottom of the ice is blocked by the boom whenever it passes through it, allowing operators to insert an oil suction pump through the gaps to remove the trapped oil. This solves the problem of traditional float-type oil booms being unusable on large areas of frozen water, effectively containing oil between the ice and the water surface.

[0075] Once the ice melts, the airbags can effectively prevent the oil boom from sinking completely into the water, thus preventing it from losing its function.

[0076] The cold resistance of rubber is mainly determined by two factors. First, it is determined by the properties of the rubber itself. Rubber molecules have low polarity and contain many double bonds, resulting in low resistance to intermolecular movement and thus good cold resistance. Rubber with high polarity and high molecular resistance has poor cold resistance. Second, it is determined by the properties of the rubber after vulcanization. During vulcanization, rubber molecules transform from a linear polymer structure to a cross-linked network macromolecular structure. The properties of this network structure play a crucial role in cold resistance.

[0077] The rubber portion of ordinary oil containment booms is primarily made of nitrile butadiene rubber (NBR) and neoprene rubber, which have good oil resistance. However, both NBR and neoprene rubber are polar rubbers with polar groups in their molecules, resulting in strong intermolecular forces. At extremely low temperatures, the rubber loses its elasticity, causing the product to harden and become unusable. Therefore, this invention aims to improve the product's low-temperature resistance while maintaining its oil resistance, so that the product can meet both oil resistance and cold-resistance requirements.

[0078] Polyolefin rubbers possess excellent low-temperature resistance, allowing for use at extremely low temperatures. However, as non-polar rubbers, they do not meet the oil resistance requirements of products. This invention aims to combine the unique properties of both olefin rubbers and oil-resistant rubbers to satisfy both oil resistance and low-temperature resistance requirements, thereby fulfilling the product's usage requirements. However, oil-resistant rubbers and olefin rubbers have significant polarity differences and are thermodynamically incompatible. Simple blending will result in severe phase separation, leading to poor vulcanization performance and products that fail to meet usage requirements.

[0079] The rubber compound of this invention uses a combination of oil-resistant rubber and low-temperature resistant rubber, and adds chlorinated polyethylene rubber as a modifier, as well as other additives such as mixing accelerators and silane coupling agents. Through the mixing process, several rubbers with different properties can be well integrated together, effectively solving this technical problem.

[0080] Because multiple rubbers are used in combination, and the compatibility of these rubbers with vulcanizing agents and auxiliary materials varies, the vulcanizing agent is unevenly distributed in the compound. Furthermore, the same vulcanizing agent and auxiliary materials exhibit different vulcanizing activities for each rubber, resulting in asynchronous vulcanization among the various rubbers. This leads to poor vulcanized rubber performance that fails to meet product performance requirements. Therefore, solving the problem of co-vulcanization between various rubbers is a key technology for manufacturing high-quality vulcanized rubber, and it is also one of the key technical challenges and innovative aspects of this product. Currently, only general-purpose vulcanizing agents are available on the market, none of which can meet the needs of co-vulcanization of multiple rubbers. There are no dedicated vulcanizing agents suitable for co-vulcanization in the domestic or international markets. Therefore, researching a vulcanizing agent with good dispersion properties in the compound, good compatibility with various rubbers, the ability to achieve co-vulcanization performance of the blended rubbers, and good low-temperature resistance is another major technical challenge that this product needs to solve.

[0081] This invention employs a method of using multiple vulcanizing agents and vulcanizing accelerators in combination. Through processing, a special multifunctional mixed vulcanizing agent (i.e., mixed accelerator) is prepared. This mixed accelerator contains multiple chemical functional groups that play a role in vulcanization. Through the synergistic effect between the various components, the technical problem of co-vulcanization between different rubbers is effectively solved, enabling the product to achieve excellent performance and meet various performance requirements.

[0082] Chlorinated polyethylene rubber exhibits good low-temperature resistance and its polarity falls between that of oil-resistant rubber and olefin-based non-polar rubbers. It shows good miscibility with both oil-resistant and non-polar olefin-based cold-resistant rubbers, making it a good mediator in the compounding process of oil-resistant and cold-resistant rubbers. It is an ideal modifier for mixing these two types of rubber. By blending a certain proportion of oil-resistant rubber, diene-based cold-resistant rubber, chlorinated polyethylene rubber, and auxiliary materials, a uniform and stable compound can be obtained.

[0083] This product uses a blend of butadiene rubber, polyisoprene rubber, and nitrile rubber, which have good low-temperature performance, and chlorinated polyethylene rubber as a modifier. Low Mooney chlorinated polyethylene rubber is preferred. According to the product performance requirements, the four rubbers are blended together in a certain proportion. Dioctyl sebacate, which has good compatibility with various rubbers and excellent cold resistance, is used as a plasticizer. Silane coupling agent is used as a treatment agent. Through the mixing process, the phase separation phenomenon that exists between different rubbers due to their different polarities is solved, and a uniform and stable compound (i.e., rubber compound) is obtained.

[0084] Organic peroxides can vulcanize a variety of high-molecular polymers, exhibiting excellent vulcanization effects on oil-resistant rubbers, cold-resistant rubbers, and chlorinated polyethylene. Furthermore, the vulcanized rubber has a C-C bond crosslinking structure, characterized by weak intermolecular forces, low steric hindrance, and strong molecular mobility, resulting in excellent cold resistance and making it an ideal vulcanizing agent for cold-resistant rubbers. In contrast, ordinary sulfur vulcanized rubbers, due to the polysulfide crosslinking structure formed during vulcanization, have strong molecular polarity, high steric hindrance, and weak molecular mobility, leading to poor cold resistance. However, peroxide vulcanization requires high vulcanization temperatures, and the vulcanization rates differ for various rubbers, preventing simultaneous vulcanization and resulting in poor tear resistance. This also makes the actual production process difficult to operate and product quality control challenging. To address this problem, this invention researches a multifunctional mixed vulcanizing agent (i.e., a mixed accelerator).

[0085] This mixed accelerator is mainly composed of peroxide vulcanizing agents, with organic sulfur-containing compounds as auxiliary vulcanizing agents, and is supplemented with other auxiliaries such as sulfur and silane coupling agents. Through process preparation, a stable comprehensive mixed vulcanizing agent (i.e., mixed accelerator) with multiple vulcanizing functions is formed.

[0086] This mixed accelerator uses a polymer structure regulator to prevent cyclization reactions of the polymers during the reaction process, thus reducing the vulcanizing crosslinking efficiency of the vulcanizing agent. It also uses a silane coupling agent to achieve uniform dispersion and synthesis of the materials through compatibilization, copolymerization, and molecular grafting among the components. This mixed vulcanizing agent, composed of multiple vulcanizing agents with different properties, forms a novel compound containing various effective functional groups through physical and chemical reactions. During vulcanization, this mixed accelerator can simultaneously undergo crosslinking reactions with various rubbers, acting as a vulcanizing bridging agent between them. Actual production testing has shown good results.

[0087] This compounding accelerator can be uniformly and stably dispersed in the rubber compound, reducing the vulcanization temperature required and coordinating the vulcanization rates among the various rubbers, thus achieving a co-vulcanization effect between them. The vulcanized rubber structure is mainly composed of CC crosslinking structures, with a small amount of monosulfide crosslinking bonds. Its performance fully meets the cold resistance requirements of the product, effectively solving the aforementioned problems.

[0088] The product manufactured by this invention possesses both the good oil resistance of ordinary oil containment booms and the special cold resistance of low-temperature oil containment booms, meeting the requirements for use under extremely cold conditions. Users have generally reported excellent performance with the product.

[0089] In summary, the beneficial effects of the present invention are as follows:

[0090] This invention develops a novel low-temperature oil containment boom that possesses both good oil resistance and excellent cold resistance. This product maintains good elasticity at extremely low temperatures, making it easy to install and deploy, and it exhibits excellent oil containment effectiveness. Detailed Implementation
