NOVELTY - High-quality recycled polyethylene plastic particle comprises 50-80 pts. wt. high-quality processed recycled polyethylene plastic, 1-5 pts. wt. antioxidant, 2-3 pts. wt. ultraviolet absorber, 3-10 pts. wt. nano stone powder, 1-2 pts. wt. lubricant, and 5-10 pts. wt. compatibilizer. USE - The high-quality recycled polyethylene plastic particle is useful in daily chemicals, sewer pipe, and tray e.g. low-end industry. ADVANTAGE - The plastic particle has good mechanical property, good chromaticity, low odor, high purity, is suitable for production of most plastic product, solves problem that the regenerated polyethylene plastic particles cannot be used for daily packaging field in existing technology, and improves application value of regenerated polyethylene plastic particles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high-quality recycled polyethylene plastic particle comprising (1) crushing high-quality processed recycled polyethylene plastic into crushed material A with a particle size of 10-20 nm, (2) adding saturated aqueous sodium chloride solution to crushed material, allowing to stand and filtering, adding hot alkaline aqueous solution, and stirring for 15-30 minutes to obtain crushed material B, (3) transferring crushed material B to plastic cleaning agent for 30-60 minutes, transferring it to clean water, stirring for 40-50 minutes, performing dehydration, separation and drying to obtain crushed material C, and (4) adding antioxidant, ultraviolet absorber, lubricant, nano-stone powder, and compatibilizer to crushed material C, melting and extruding to granulate at 170-240℃ to obtain high-quality recycled polyethylene plastic particle.
