Embodiment Construction

[0013] 1. Granulation

[0014] Crush the natural straw to 100-150 mesh and set aside.

[0015] Crush the cork powder to 600-800 mesh and set aside.

[0016] The crushed natural straw, cork powder, polypropylene and titanate coupling agent, stearic acid, ethylene bisstearic acid amide, and titanium dioxide account for 8-20% and 8-12% of the total mass of raw materials, respectively. , 64~70%, 0.3~0.5%, 0.7~1%, 2.5~3%, 0.5~1% are mixed evenly, and placed in a twin-screw mixing extruder after high temperature dehydration, at 150~165 Extrusion and granulation under the condition of ℃, the raw material particles of the present invention are obtained, and the density is 900~930 kg / m after testing 3 .

[0017] 2. Application

[0018] The plastic particles of the present invention can replace general polypropylene for production. The present invention can be placed in an injection molding machine, and the injection molding temperature is selected to be 170-180°C, and different pr...

Abstract

The invention discloses lightweight wood-plastic mixed granules containing straws and a production method thereof, and relates to the technical field of plastic raw material granules. After natural straws, cork powder, polypropylene and plastic aid are mixed, the mixture is extruded and granulated through double screws; the density of the formed granules can be 900kg/m<3>, and the raw materials or the wastes can be separated together with the polypropylene in a centrifugal separation system; and the mixed granules have low machining temperature, good mechanical strength and excellent machinability, and can be repeatedly machined and formed without changing the density. By the production method, the consumption of non-degradable petroleum-based plastic can be reduced, oil crisis is retarded, and an innocent treatment and a good purpose are provided for agricultural wastes; and the production method is favorable for saving resources and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of production of plastic raw material particles and products thereof. Background technique [0002] With the great development of the plastics industry and a large number of applications of plastics, the problem of waste plastics is becoming more and more serious. Traditional plastics cannot be naturally degraded after being discarded and cause serious pollution to soil, groundwater and air. Direct recycling is half the effort and inefficient. The resulting white pollution has become a global problem, and the pressure on environmental protection is extremely huge. [0003] Crop stalks are agricultural waste. Since there is no better way, the abandoned crop stalks are usually simply incinerated, which not only causes serious pollution to the environment, but also causes nutritional deficiencies in the soil itself. cause a fire and pose a safety hazard. Contents of the invention [0004] The purpose of th...
