Abstract

The invention provides a high-strength and low-temperature-resistant plastic bucket and a preparation method thereof. The preparation method comprises the following steps: (1) putting polyethylene, nano-modified epoxy resin and glass-fiber-reinforced vinyl ester resin into a mixer, and evenly stirring and mixing at certain temperature; (2) sequentially adding aramid fibers, basalt fibers, dibenzylidene sorbitol, an ultraviolet light absorber UV-326, an antioxidant 1010, an antioxidant 168, oxidized polyethlene wax and activated quartz powder into the mixer, and evenly stirring and mixing; (3) heating an obtained mixture, putting the heated mixture into a double-screw extruder and extruding plastic particles; (4) putting the plastic particles into an extrusion hollow blow molding machine, and extruding a tubular blank material; (5) putting the tubular blank material into a mould of the extrusion hollow blow molding machine, controlling the temperature of the mould and the pressure of the compressed air, and carrying out hollow blowing to obtain the plastic bucket. The plastic bucket provided by the invention is good in low temperature impact resistance and tensile strength, is non-toxic and harmless, and simple and practicable in technology.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a high-strength and low-temperature resistant plastic bucket and a preparation method thereof. Background technique [0002] Plastic barrels are mostly used for the storage and transportation of various liquids, and have good characteristics for special dangerous goods packaging. They are not fragile, rust-free, light in weight, etc., and are resistant to oil and strong corrosion. They are mostly used for heat preservation and moisture-proof , pressure-resistant and corrosion-resistant dangerous goods packaging. Plastic barrels are mostly made of polyethylene, polypropylene, polyester and other plastic blow molding, injection molding, blister molding, and rotational molding. They are mostly used to hold liquid and solid items in industries such as chemicals, pesticides, medicine, food, hardware, electronics, and electromechanical industries. . The main raw material for the pr...
