Description

Technical Field

[0001] The invention belongs to the technical field of helmet manufacturing materials, and in particular relates to a method for preparing a new material for a helmet which is impact-resistant, high-voltage-resistant and highly insulating. Background Art

[0002] Safety helmets are the most common personal labor protection products (for the head). They can relieve and disperse instantaneous impact forces in a short period of time, reduce instantaneous impact forces, and reduce the degree of head impact injuries. Electrician safety helmets are divided into two types: ordinary protective safety helmets (mainly made of ABS material, mainly for anti-collision and impact protection) and insulated high-voltage safety helmets (can withstand 10-20kv voltage, mainly made of glass fiber and ultra-high molecular weight polyethylene). Ordinary safety helmets mainly provide head impact protection; insulated safety helmets provide insulation isolation protection for the human body against high-voltage equipment, and can prevent workers from being injured by high-voltage electric shock when they approach or touch high-voltage equipment.

[0003] Although ordinary protective helmets and insulating high-voltage helmets are different types of helmets designed to meet different working environments and safety requirements, there are still the following disadvantages when using them separately:

[0004] 1. Double purchase cost: Both types of helmets must be purchased separately, which results in high purchase cost;

[0005] 2. Inconvenient to carry and use: Workers need to choose different safety helmets according to different working environments and work contents during actual operations, and need to change safety helmets frequently;

[0006] 3. Potential safety risks: Workers may be busy or mentally negligent during the operation. Workers may wear helmets that are not suitable for the working conditions. For example, if they use ordinary helmets as insulating helmets for live work, they may get electric shocks. If they use insulating helmets as ordinary helmets for ground work, they will not be able to prevent objects from hitting them or falling from heights. The workers' heads will lose protection, which will cause safety hazards.

[0007] 4. Complex storage and management: The two types of helmets require two sets of storage and management systems, which are stored in different places according to different standards. The maintenance and regular inspection and preventive testing requirements are also different, which increases the management workload and the chance of error. Summary of the invention

[0008] In order to solve the problems of double purchase cost, inconvenience in carrying and using, potential safety risks, and complex storage and management, the basic concept of the technical solution adopted by the present invention is:

[0009] A new material for a safety helmet that is impact-resistant, high-voltage-resistant and highly insulating, comprises a helmet shell base material, an inorganic nano-functional filler, a modified fiber material, a flame retardant, an antioxidant, an ultraviolet absorber, an ultra-high molecular weight polyethylene and a toughening agent elastomer. The helmet shell base material is a strong, tough and easy-to-process polymer material. The inorganic nano-functional filler is used to fill and toughen the helmet shell base material. The inorganic nanoparticles include, for example, nano-calcium carbonate, nano-silicon dioxide, boron nitride, and two-dimensional nanomaterial mxene. The modified fiber material is a surface-treated glass fiber, natural fiber or carbon fiber. The flame retardant is mainly a halogen-free flame retardant, such as aluminum hydroxide, magnesium hydroxide, and a nitrogen-phosphorus composite flame retardant as a first flame retardant.

[0010] As a preferred embodiment of the present invention, the base material of the cap shell is mainly ABS and PC, and several materials can be appropriately considered to be blended, such as PP, POE, etc. At the same time, according to the test results of impact resistance test, high voltage breakdown resistance, insulation and flame retardant performance, etc., a suitable material combination is selected, and the addition amount is 50-80%.

[0011] As a preferred embodiment of the present invention, the inorganic nano-functional filler has unique surface effect, volume effect, quantum size effect and macro quantum tunneling effect, which not only enhances the strength and toughness of the material, but also has excellent flame retardant and insulating properties, and improves the high-voltage breakdown resistance. The addition amount is 5%-30%.

[0012] As a preferred embodiment of the present invention, the modified fiber material: the fiber composite material is prepared by adopting the method of fiber-reinforced resin matrix, which can greatly improve the rigidity and strength of the resin matrix, and the addition amount is 10-20%.

[0013] As a preferred embodiment of the present invention, the flame retardant: chlorinated polyethylene (CPE) is used as an elastomer, which has good compatibility with ABS, increases the compatibility of the resin matrix, and can also be used as a second flame retardant, with an addition amount of 1-4%.

[0014] As a preferred embodiment of the present invention, the antioxidant can be selected from one of antioxidant 1010, antioxidant 1076, antioxidant 2246 and antioxidant 246, and the added amount is 0.1%-2%.

[0015] As a preferred embodiment of the present invention, the ultraviolet absorber is selected from benzotriazoles, and the addition amount is 0.1%-2%.

[0016] As a preferred embodiment of the present invention, the ultra-high molecular weight polyethylene is added in an amount of 3%-5%, and the toughening agent elastomer can be made of POE, EPDM and other materials, and the addition amount is 5%-10%.

[0017] The preparation method of the new material for the impact-resistant, high-voltage-resistant and highly insulating safety helmet comprises the following steps:

[0018] S1: Surface modification of inorganic nano-functional fillers: 20 g of silicon dioxide powder was dispersed in 200 ml of water (500 ml three-necked flask) by ultrasonic wave, and then 8 g of iminodiacetic acid was added, stirred at room temperature for 6 h, and centrifuged to obtain the product;

[0019] S2: The obtained product was dispersed in 200 ml of deionized water, and 20 g of zinc acetate was added, followed by slow addition of 10 ml of aqueous ammonia, and the mixture was reacted at 60° C. for 24 h, and finally centrifuged and dried to obtain the modified silica powder;

[0020] S3: Compounding of flame retardants: 4 g of aluminum hydroxide was weighed as the first flame retardant, and it was blended with 100 g of chlorinated polyethylene (CPE), and a compounded flame retardant masterbatch was prepared by granulation through a twin-screw extruder, and the six-stage temperatures of the extruder were: 120° C., 125° C., 130° C., 135° C., 140° C., and 135° C.;

[0021] S4: Surface etching of carbon fiber: prepare a 60% HNO3 solution, immerse the pretreated carbon fiber in it for oxidation etching, the immersion time is about 20 minutes, after oxidation treatment, the carbon fiber is thoroughly cleaned to remove the residual oxidant to obtain modified carbon fiber, and neutralization treatment is required if necessary;

[0022] S5: ABS, modified silica powder, compound flame retardant, modified carbon fiber, antioxidant 1010, benzotriazole UV absorber, ultra-high molecular weight polyethylene, and toughening agent elastomer POE are charged into a high-speed mixer according to the formula ratio and mixed evenly, and then sent to a twin-screw extruder for extrusion and granulation to obtain ABS modified material. The temperatures of the six sections of the extruder are: 155°C, 160°C, 165°C, 170°C, 175°C, and 170°C respectively.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In the present invention, the electrician protection safety helmet and the insulating high-voltage resistant safety helmet are combined into one, which has the multi-functions of impact resistance, insulation and high-voltage resistance. It is made of special high-strength high-voltage resistant insulating polymer modified material to meet the safety requirements in different working environments. At the same time, important progress has been made in reducing costs, improving convenience and reducing safety risks.

[0025] In the present invention, in order to make the ABS material free of halogen flame retardants and provide ABS with better flame retardant performance, the halogen-free flame retardant is firstly blended with chlorinated polyethylene (CPE), and CPE is used as a second flame retardant. The CPE not only has good compatibility with the matrix resin, but also has good compatibility with inorganic fillers and additives due to the polarity of the molecule. The nano inorganic material has unique surface effect, volume effect, quantum size effect and macro quantum tunnel effect, and is blended with ABS through melt extrusion, nano intercalation technology and other technologies, and a double electric layer is formed on the surface of inorganic nano particles by using surface modification technology, so as to solve the shortcomings of poor affinity, easy agglomeration, uneven dispersion and the like between the inorganic filler and the ABS substrate, and the ultra-high molecular weight polyethylene material has excellent mechanical properties and insulation properties, and is added as an insulating agent in the formula of the anti-collision and high-voltage insulating multifunctional helmet shell material, so as to improve the insulation and voltage resistance performance of ABS.
