Description

Technical Field

[0001] This invention relates to the field of functional polymer composite materials technology, and in particular to an environmentally friendly transparent chlorinated polyethylene rubber cable material and its preparation method. Background Technology

[0002] Chlorinated polyethylene rubber (CM) is an elastomer with excellent comprehensive properties, produced by a chlorination substitution reaction of high-density polyethylene (HDPE). Due to its good resistance to heat and oxygen, acids and alkalis, oils, ozone, flame retardancy (due to the presence of chlorine), and mechanical properties, it is widely used in the wire and cable industry. The amorphous structure of chlorinated polyethylene rubber (CM) itself gives it a certain degree of light transmittance, while traditional chlorinated polyethylene rubber (CM) cable materials, due to the filling of carbon black and inorganic materials, result in poor light transmittance in chlorinated polyethylene rubber cables.

[0003] With the development of applications in smart homes, medical and scientific research equipment, decoration and creative design, and smart mining, the demand for translucent cables that combine the flexibility and transparency of rubber is increasing. However, existing technologies using transparent PVC, silicone rubber, and polyurethane to manufacture translucent cables have various drawbacks. PVC has poor weather resistance and temperature resistance; silicone rubber has poor resistance to damage and is expensive; and polyurethane has poor flame retardancy, high cost, and is prone to hydrolysis.

[0004] Therefore, developing a rubber cable material based on chlorinated polyethylene rubber (CM) that retains its inherent advantages while achieving light transmittance has significant market value and technical importance. The technical challenges lie in finding a filler with a refractive index that matches that of chlorinated polyethylene rubber (CM) after removing carbon black and inorganic fillers, and in balancing the conflicting demands on environmental friendliness, flame retardancy, mechanical properties, light transmittance, and durability. Summary of the Invention

[0005] In view of this, the present invention proposes an environmentally friendly transparent chlorinated polyethylene rubber cable material and its preparation method to solve the above problems.

[0006] The technical solution of this invention is implemented as follows: An environmentally friendly, transparent chlorinated polyethylene rubber cable material, comprising the following raw materials in parts by weight: 90-100 parts chlorinated polyethylene, 10-20 parts toughening agent, 20-30 parts transparent reinforcing agent, 8-15 parts environmentally friendly plasticizer, 5-10 parts stabilizer, 30-50 parts flame retardant system, 5-10 parts acid absorber, 4-7 parts peroxide crosslinking system, 0.5-1.5 parts processing aid, 0.5-1.5 parts antioxidant, and 0.5-1 part ultraviolet absorber. The transparent reinforcing agent is fumed silica surface-treated with a silane coupling agent. The processing steps of the fumed silica include the following steps: a. Pretreatment: The fumed silica is soaked in an acidic or oxidizing solution to adjust the hydroxyl content on its surface; b. Synergistic coupling: The pretreated silica is dispersed in an alcohol-water mixed solvent, and silane coupling agents and titanate coupling agents are added. The mixture is stirred and reacted under heating conditions so that the coupling agents are grafted onto the surface of the silica. c. Plasma activation: The product obtained in step b) is subjected to plasma treatment in an inert gas atmosphere; d. Shaping: Vacuum drying is performed on the plasma-treated silica to control the final moisture content.

[0007] Preferably, the chlorinated polyethylene has a chlorine content of 35% to 40%, and low residual crystallization and uniform chlorine atom distribution to ensure that the matrix material itself has good light transmittance.

[0008] Preferably, the toughening agent is ethylene-octene copolymer (POE) with a melt index of 1-3 g / 10 min, a hardness of 70-80, and a light transmittance of 85%-90%. The addition of POE can effectively improve the low-temperature brittleness of CM and form a continuous phase with CM with a similar refractive index, together constituting a transparent matrix.

[0009] Preferably, the fumed silica has a particle size of 10-30 nm, a specific surface area ≥200 m² / g, and a refractive index of 1.46-1.55. The silane coupling agent is preferably KH-550 or KH-570.

[0010] More preferably, the processing technology for the fumed silica includes the following steps: a. Pretreatment: First, soak the fumed silica in a 5-8% hydrochloric acid solution or a 3-5% hydrogen peroxide solution for 1.5-2.5 hours. This step can effectively clean the surface and adjust the surface hydroxyl content to the optimal reactivity state of 1.8-2.2 mmol / g.

[0011] b. Synergistic Coupling: Pretreated silica is added to a 40-60% v / v ethanol-water solution at a mass-to-volume ratio of 1:5-10 g / mL. Then, 3-5% (by weight of silica) of silane coupling agent and 0.5-1% (by weight of titanate coupling agent) are added, and the mixture is stirred at a constant temperature of 70-75℃ for 3-4 hours. Utilizing the synergistic effect of titanate and silane, the grafting rate of the coupling agent on the silica surface can be significantly improved, achieving a final grafting rate ≥92%.

[0012] c. Plasma activation: The coupled silica is placed in a vacuum plasma treatment instrument, and argon gas is introduced at a flow rate of 10-15 sccm. Treatment is carried out for 10-15 minutes at a power of 100-120 W and a pressure of 40-60 Pa. This step further opens up the inert groups on the surface of the silica, generating more active sites and greatly enhancing its interfacial bonding with the CM rubber matrix.

[0013] d. Shaping: Finally, vacuum dry at 85~95℃ for 2~4 hours, strictly controlling the moisture content of the final product to ≤0.2%. This process ensures that the silica has excellent dispersibility and compatibility in the CM matrix, which is the key to achieving high light transmittance and high reinforcement.

[0014] Preferably, the flame retardant system is composed of reactive phosphate liquid flame retardant (RDP or BDP) and nano-active magnesium hydroxide in a weight ratio of 1:(1~1.5). The refractive index of the reactive phosphate is close to that of CM, and it can be chemically bonded to the polymer network to avoid migration and precipitation, thus achieving long-lasting flame retardancy.

[0015] Preferably, the peroxide crosslinking system consists of a peroxide vulcanizing agent and a co-crosslinking agent in a mass ratio of 1:(0.8~1.5); the peroxide vulcanizing agent is dicumyl peroxide (DCP) or dicumyl peroxide (BIPB); the co-crosslinking agent is triallyl isocyanurate (TAIC) or trimethylolpropane trimethacrylate (PL-400); this optimized ratio ensures the best balance between crosslinking efficiency and network structure stability.

[0016] Preferably, the environmentally friendly plasticizer is adipate ether ester RS-107; the stabilizer is a liquid calcium-zinc composite stabilizer with a calcium content of 8%~10% and a zinc content of 2%~3%; the acid absorber is active nano magnesium oxide; the processing aid is stearic acid or low molecular weight polyethylene wax; the antioxidant is hindered phenolic antioxidant 1076 or 1010; and the ultraviolet absorber is UV-531 or UV-326.

[0017] This invention provides a method for preparing the above-mentioned environmentally friendly transparent chlorinated polyethylene rubber cable material, comprising the following steps: S01: Accurately dispense ingredients according to the stated weight proportions; S02: Dry the fumed silica at 105±5℃ for 1-3 hours to remove moisture; S03: Put the dried chlorinated polyethylene (CM) and toughening agent (POE) into an internal mixer and mix them at a low speed of 20-30 rpm for 1-2 minutes to slowly and evenly raise the temperature of the rubber compound to 80-90℃. S04: Add stabilizer, flame retardant system, environmentally friendly plasticizer, pretreated fumed silica, processing aids, etc. in sequence. Close the top plug and increase the speed to 30-40 rpm, mixing for 2-4 minutes. During this process, strictly control the temperature of the mixing chamber of the internal mixer at 130-135℃. Discharge the material when the temperature reaches the set value to obtain a first-stage compound. This high-temperature stage aims to achieve full plasticization and initial dispersion of the material.

[0018] S05: After cooling a section of rubber compound to 90~100℃, filter it through a rubber filter with a mesh size of 40 or 60 to remove any possible gel and impurities.

[0019] S06: Cool the filtered compound to room temperature (25±2℃), then re-pick it into the internal mixer or transfer it to a two-roll mill, and add the peroxide crosslinking system. This step requires strict control of the mixing temperature below 100℃, mixing for 2-3 minutes to ensure uniform dispersion of the vulcanizing agent and prevent scorching.

[0020] S07: After the vulcanization is completed, the rubber compound is cooled by a two-roll mill, formed into triangular bundles, and passed through a thin mill several times. Finally, it is calendered into sheets by a calender, packaged, and stored at room temperature for later use.

[0021] Compared with the prior art, the beneficial effects of the present invention are: This invention successfully solves the core problem of balancing high light transmittance and excellent mechanical properties by constructing a chlorinated polyethylene / ethylene-octene copolymer (CM / POE) transparent matrix and employing a pretreatment-synergistic coupling-plasma activation process to deeply modify fumed silica, achieving extreme dispersion within the matrix. Simultaneously, a reactive phosphate ester / nano-magnesium hydroxide composite flame-retardant system is used, preventing flame retardant migration and precipitation through chemical bonding, resulting in durable and environmentally friendly high flame retardancy. Furthermore, the material exhibits excellent thermal stability, oil resistance, and low-temperature resistance, ensuring long-term durability in complex environments. Combined with a special process of high-temperature primary refining and low-temperature sulfurization, a high-performance transparent cable material with balanced, stable, and reliable properties is ultimately obtained, showing broad application prospects in smart homes, decorative lighting, and other fields.

[0028] Comparative Example 1 The formulation of this comparative example is exactly the same as that of Example 2, the only difference being the processing technology of the fumed silica: After drying fumed silica at 105°C for 2 hours, without pretreatment, synergistic coupling, or plasma activation, a dry mixing process was directly employed: fumed silica was mechanically mixed with 4% (by weight) of KH-550 silane coupling agent in a high-speed mixer at 80°C for 15 minutes. It was then dried at 100°C for 2 hours to obtain the comparative fumed silica filler.

[0029] Comparative Example 2 The traditional formula is used: 100 parts CM, 30 parts carbon black N330, 20 parts calcium carbonate, 15 parts DOP plasticizer, 5 parts tribasic lead sulfate, 3 parts DCP, and 2 parts TAIC, prepared according to conventional processes.

[0030] Table 1 shows the comparative data of the light-transmitting chlorinated polyethylene rubber cable material produced by the above preparation method, including tests such as heat aging, tear resistance, low-temperature tensile strength, and mineral oil immersion.

[0031] Testing standards: Tensile strength and elongation at break (GB / T528-2009), heat aging test (GB / T3512-2014), tear strength (GB / T529-2008), mineral oil aging test (GB / T1690-2010), oxygen index (GB / T2406.2-2009), and light transmittance (GB / T2410-2008).

[0032] Table 1

[0033] Results analysis: The environmentally friendly transparent chlorinated polyethylene rubber cable material prepared by this invention exhibits excellent performance in terms of light transmittance, mechanical properties, aging resistance, low-temperature adaptability, and flame retardancy, meeting all the required specifications: light transmittance of 58%-68%, tensile strength of 13.5-14.3 MPa, tensile strength showing a positive change after heat aging (+9%-+12%), elongation at break at -35℃ of 75%-92%, and oxygen index of 34%-37%.

[0034] The comparison shows that Comparative Example 1, due to the simplified modification process of fumed silica, resulted in silica agglomeration, reducing the light transmittance to 35%. Tensile strength, tear strength, and low-temperature performance all failed to meet standards, verifying the crucial role of the optimized silica treatment process in the overall material performance. Comparative Example 2, with its traditional cable material formulation, exhibited a light transmittance of only 2%, and its mechanical properties, aging resistance, and low-temperature adaptability were significantly inferior to the present invention. This further demonstrates that the present invention, through its formulation and process design of a transparent matrix (CM+POE), modified silica with a matching refractive index, and environmentally friendly functional additives, can effectively balance light transmittance, mechanical properties, and weather resistance, possessing significant technical advantages and application value.
