Multifunctional filled masterbatch for polyethylene and preparation method thereof

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...
