Embodiment 1

[0027] Add 40 parts of copolymerized PP, 43 parts of coffee grounds, 7 parts of talcum powder, 0.3 parts of ultraviolet absorber, 0.4 parts of antioxidant, and 0.3 parts of ethylene bisstearamide into the high-speed mixing tank to mix them evenly; then, in the double Screw extruder mixing, the temperature of each section of the twin-screw is: T1 = 160 ° C, T2 = 170 ° C, T3 = 175 ° C, T4 = 180 ° C, T5 = 185 ° C, T6 = 190 ° C, twin-screw extrusion The rotation speed of the machine is r=350r.min-1. Finally, a high-strength PP material containing coffee grounds is obtained through extrusion, cooling and pelletizing.

Embodiment 2

[0029] Add 45 parts of copolymerized PP, 45 parts of coffee grounds, 9 parts of talcum powder, 0.3 parts of ultraviolet absorber, 0.4 parts of antioxidant, and 0.3 parts of ethylene bisstearamide into the high-speed mixing tank to mix them evenly; then, in the double Screw extruder mixing, the temperature of each section of the twin-screw is: T1 = 160 ° C, T2 = 170 ° C, T3 = 175 ° C, T4 = 180 ° C, T5 = 185 ° C, T6 = 190 ° C, twin-screw extrusion The rotation speed of the machine is r=350r.min-1. Finally, a high-strength PP material containing coffee grounds is obtained through extrusion, cooling and pelletizing.

Embodiment 3

[0031] Add 35 parts of copolymerized PP, 40 parts of coffee grounds, 5 parts of talcum powder, 0.3 parts of ultraviolet absorber, 0.4 parts of antioxidant, and 0.3 parts of ethylene bisstearamide into the high-speed mixing tank to mix them evenly; then, in the double Screw extruder mixing, the temperature of each section of the twin-screw is: T1 = 160 ° C, T2 = 170 ° C, T3 = 175 ° C, T4 = 180 ° C, T5 = 185 ° C, T6 = 190 ° C, twin-screw extrusion The rotation speed of the machine is r=350r.min-1. Finally, a high-strength PP material containing coffee grounds is obtained through extrusion, cooling and pelletizing.

Abstract

The invention provides a high-strength PP material containing coffee grounds. The high-strength PP material comprises the following components: 35-45% of copolymerized PP, 30-45% of the coffee grounds, 5-10% of talcum powder, 0.2-0.4% of an ultraviolet light absorber, 0.2-0.4% of an antioxidant and 0.2-0.5% of a lubricant. The method comprises the following steps: adding the components into a mixing cylinder according to the ratio, and uniformly mixing; adding the mixture into a double-screw extruder for mixing; wherein the extrusion temperature of the first section and the second section of the double-screw extruder is 160-170 DEG C, the extrusion temperature of other sections is 170-190 DEG C, and the total residence time of reactants in the double-screw extruder is 3-5 minutes; and finally, extruding the obtained material, cooling and dicing to obtain the high-strength PP material containing the coffee grounds. By modifying PP, environmental protection and flame retardance are achieved, and the outdoor long-term anti-aging use requirement can be met.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing high-strength PP material containing coffee grounds. Background technique [0002] Polypropylene, referred to as PP, is a colorless, odorless, non-toxic, translucent solid substance. [0003] Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., polypropylene has been rapidly used in machinery, automobiles, electronic appliances, construction, textiles, and packaging since its inception. It has been widely developed and applied in many fields such as agriculture, forestry, fishery and food industry. [0004] In recent years, with the rapid development of my country's pack...
