Technical Field

[0001] The invention relates to the technical field of masterbatches, in particular to an anti-aging and anti-sticking masterbatch for blow molding PE and a preparation method thereof. Background Art

[0002] Blow molding is a method of manufacturing hollow thermoplastic parts. Well-known blow molding objects include bottles, barrels, cans, boxes and all containers for packaging food, beverages, cosmetics, medicines and daily necessities. Large blow-molded containers are usually used for packaging chemical products, lubricants and bulk materials. Other blow-molded products include balls, bellows and toys.

[0003] At present, masterbatch needs to be added to the slurry used in blow molding to improve the performance of the slurry. However, during the application process, the performance of the masterbatch in traditional technology will decline significantly with the change of time, which directly affects the life of the finished product.

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] An anti-aging and anti-sticking masterbatch for blow molding PE, comprising the following components by weight: 40% to 60% of carrier resin, 15% to 33% of filler, 1% to 2.2% of plasticizer, 3% to 6.25% of anti-aging agent, 1.8% to 5.85% of anti-sticking agent, 1.4% to 1.8% of colorant, 2% to 3.6% of light stabilizer, and 5% to 9% of antistatic agent;

[0025] Furthermore, the material of the carrier resin is polyethylene, which is also called vinyl polymer resin. It is a common plastic material, which is formed by addition polymerization of ethylene monomers, and also includes a small amount of impurities, such as butadiene, hexadiene and other unsaturated hydrocarbons. Polyethylene has good mechanical strength, wear resistance, corrosion resistance and thermoplasticity, and can effectively improve the strength of the masterbatch;

[0026] In detail, the filler is at least one of phenolic resin, glass fiber, hydroquinone and carbon powder. Phenolic resin is a thermosetting synthetic resin obtained by polycondensation of phenolic monomer and polyurethane prepolymer, which can effectively improve the electrical insulation, heat resistance, corrosion resistance and wear resistance of the masterbatch;

[0027] Glass fiber is an inorganic non-metallic material, the main component of which is silicate. It is made through a series of process steps such as high-temperature melting, elongation and cooling. While ensuring the strength of the masterbatch, it can also reduce the weight of the masterbatch and improve the corrosion resistance and wear resistance of the masterbatch.

[0028] Hydroquinone has the characteristics of high efficiency and broad spectrum, and can effectively inhibit oxidation reactions, thereby protecting the masterbatch from oxidation;

[0029] Carbon powder can effectively improve the mechanical properties, stiffness and toughness of the catalog;

[0030] Further, the plasticizer is at least one of diheptyl phthalate and dioctyl phthalate, and dioctyl phthalate is an organic ester compound, which has good compatibility with most synthetic resins and rubbers used in industry except cellulose acetate and polyvinyl acetate, and has good comprehensive performance, good mixing performance, high plasticizing efficiency, low volatility, good low-temperature flexibility, water extraction resistance, high electrical properties, good heat resistance and weather resistance, so the quality of the finished product of the masterbatch can be guaranteed;

[0031] Diheptyl phthalate is a chemical substance with the molecular formula of C22H34O4. It can effectively improve the compatibility of masterbatch, and has excellent plasticizing efficiency, tensile strength and cold resistance, and can improve the quality of finished masterbatch.

[0032] Furthermore, the anti-aging agent is at least one of hydroquinone, coke black and titanium dioxide, and hydroquinone and coke black can delay the aging and degradation of the masterbatch;

[0033] Titanium dioxide is an important inorganic chemical pigment, the main component of which is titanium dioxide. Adding titanium dioxide to masterbatch can improve the heat resistance, light resistance, and weather resistance of the masterbatch product, improve the physical and chemical properties of the masterbatch product, enhance the mechanical strength of the product, and extend its service life.

[0034] In detail, the anti-sticking agent is at least one of talc and nano-silicone wax, and the talc is a magnesium silicate mineral talc family talc, the main component of which is hydrated magnesium silicate, which can increase the stability of the masterbatch shape, tensile strength, shear strength, flexural strength and pressure strength, so that the masterbatch particle size can be evenly dispersed;

[0035] Preferably, the light stabilizer is at least one of zinc oxide and ascorbate. The principle of zinc oxide shielding ultraviolet rays is absorption and scattering. Zinc oxide is an N-type semiconductor. The electrons in the valence band can accept the energy in the ultraviolet rays and undergo transitions. This is also the principle of their absorption of ultraviolet rays. The function of scattering ultraviolet rays is related to the particle size of the material. When the size is much smaller than the wavelength of ultraviolet rays, the particles can scatter the ultraviolet rays acting on them in all directions, thereby reducing the intensity of ultraviolet rays in the irradiation direction, thereby improving the anti-ultraviolet performance of the masterbatch.

[0036] Ascorbate, also known as peroxide salt, is composed of hydrogen peroxide and ascorbic acid and has the following characteristics:

[0037] 1. It can inhibit the aging process of masterbatch and extend its service life;

[0038] 2. Environmentally friendly, non-toxic, odorless and pollution-free;

[0039] 3. The effect is more lasting and reliable;

[0040] In detail, the antistatic agent is at least one of montmorillonite, polyacrylic acid salt and polyacrylic acid salt.

[0041] In summary, the anti-aging and anti-sticking masterbatch for blow molding PE can ensure the application strength of the masterbatch while taking into account the overall anti-aging performance through overall coordination, which greatly guarantees the finished product life of the masterbatch product.
