Embodiment Construction

[0016] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0017] A multifunctional filler masterbatch for polyethylene, the components of which are proportioned by mass percentage: polyethylene resin 24%, composite filler 30%, bisphenol A-bis(diphenyl phosphate) flame retardant 20%, Antistatic agent 10%, anti-aging agent 8%, ethylene-methyl acrylate-glycidyl methacrylate terpolymer 5%, antioxidant 1010 and antioxidant 168 in a mass ratio of 1:1 1%, EVA wax 2%. Wherein, the composite filler is a mixture of heavy calcium carbonate, acicular wollastonite and precipitated barium sulfate with a mass ratio of 2:1:1, which is activated by an aluminum-titanium composite coupling agent. The heavy calcium carbonate The particle size of the acicular wollastonite is between 5 and 20 μm, the particle size of the precipitated barium sulfate is 0.5 to 1 μm; the antistatic agent is a sulfonate anionic surfactant Antis...

Abstract

The invention discloses a multifunctional filled masterbatch for polyethylene and a preparation method thereof. The multifunctional filled masterbatch for polyethylene comprises the following ingredients, by weight, 10-30% of polyethylene resin, 20-40% of a composite filler, 15-25% of a fire retardant, 10-20% of an antistatic agent, 2-8% of an anti-ageing agent, 2-5% of a compatilizer, 0.5-2% of an antioxidant and 0.1-2% of EVA wax. The composite filler is a composite filler obtained by activating a mixture of heavy calcium carbonate, needle-shaped wollastonite and precipitated barium sulphate at the mass ratio of 2:1:1 by the use of an aluminium-titanium compound coupling agent. The invention has the following beneficial effects: when applied in production of polyethylene, the multifunctional filled masterbatch has multifunctional modification effects such as flame retardance, reinforcing, anti-static electricity, ageing resistance and the like on a polyethylene material; using effect of the multifunctional filled masterbatch is good and costs are low; and a preparation technology is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a multifunctional filler masterbatch for polyethylene and a preparation method thereof. Background technique [0002] Polyethylene is a light-weight, non-toxic thermoplastic with high strength, good chemical corrosion resistance, and convenient molding and processing. It is widely used in packaging, chemical industry, construction, machinery and food processing and other fields. Because filler masterbatch can save resin plastic and reduce cost, polyethylene filler masterbatch has developed rapidly in our country. However, many manufacturers simply add low-priced fillers in production to greatly reduce costs, but ignore the quality of materials. Compatibility problems, which lead to a decline in the quality and performance of the produced polyethylene products. Contents of the invention [0003] The object of the present invention is to provide a multifunctional fille...
