Embodiment 1

[0027] The technical solution adopted in the present invention is a new type of wood-plastic composite material, which is made from wood powder raw materials, solid waste, and thermoplastics through processes such as crushing, blending, granulation, and extrusion molding. ;

[0028] The preparation method of the wood-plastic composite material comprises the following steps:

[0029] (1) Dry and grind the wood powder raw material to 90 mesh, dry and pulverize the solid waste to 200 mesh, and disperse the waste fiber textiles evenly after drying;

[0030] (2) Weigh 30 parts of recycled PE, 60 parts of wood powder raw materials, 7 parts of solid waste iron tailings powder, 10 parts of waste fiber textiles, 1 part of maleic anhydride grafted PE, 1 part of ethylene wax, 1 part of paraffin wax, stearin Add 0.5 part of acid and 0.5 part of zinc stearate into the mixer and mix for 20 minutes;

[0031] (3) Extrude and granulate the mixed raw materials with a twin-screw extruder to ob...

Embodiment 2

[0035] On the basis of Example 1, this embodiment is a new type of wood-plastic composite material. The wood-plastic composite material uses wood powder, waste fiber textiles, solid waste, and thermoplastics as raw materials, and is crushed, blended, and manufactured. Granules and extrusion molding processes;

[0036] The preparation method of the wood-plastic composite material includes the following steps: (2) weighing 25 parts of recycled PE, 60 parts of wood flour raw materials, 7 parts of solid waste, 15 parts of waste fiber textiles, 1 part of maleic anhydride grafted PE, ethylene wax 1 part, 1 part of paraffin, 0.5 part of stearic acid, 0.5 part of zinc stearate, added to the mixer, and mixed for 25 minutes;

[0037] The raw material of wood flour is discarded mushroom sticks. The solid waste is iron tailings. Other parts are identical with embodiment 1.

Embodiment 3

[0039] On the basis of Example 1, this example is a new wood-plastic composite material,

[0040] The steps of the preparation method of the wood-plastic composite material:

[0041] (2) Weigh 30 parts of recycled PE, 50 parts of wood powder raw materials, 7 parts of solid waste, 10 parts of waste fiber textiles modified with silane coupling agent KH-550, 0.65 parts of maleic anhydride grafted PE, Add 0.75 parts of ethylene wax, 0.85 parts of paraffin wax, 0.65 parts of stearic acid, and 0.75 parts of zinc stearate into the mixer, and mix for 20 minutes;

[0042] The raw material of wood flour is discarded mushroom sticks or other waste wood. Solid waste is iron tailings, other tailings or red mud. Other parts are identical with embodiment 1.

Abstract

The invention discloses a novel wood-plastic composite material, which is prepared from a wood meal raw material, waste fiber textiles, solid wastes and thermoplastics by the processes of crushing, blending, granulation, extrusion molding and the like. According to the novel wood-plastic composite material, waste mushroom stems, the waste fiber textiles, the solid wastes and the like can be comprehensively utilized, and the wood-plastic composite material prepared from the waste mushroom stems, the waste fiber textiles and the solid wastes is low in cost and high in mechanical performance and service performance, and has the characteristics of low cost and strong strength; in addition, a production method is easy to operate, has lower requirements on a process condition and production equipment, and has broad market application prospect, and large-scale production can be implemented.

Description

technical field [0001] The invention relates to a composite material, in particular to a novel wood-plastic composite material. Background technique [0002] There are many kinds of mushrooms, which are rich in nutritional value. They have the functions of improving the body’s immunity, relieving cough and reducing phlegm, and anti-cancer. They are deeply loved by people all over the world. As the scale of mushroom farming expands, more and more discarded mushroom sticks are produced. There is no report on the utilization of discarded mushroom sticks in the literature search. Mushroom farming enterprises mostly dispose of them in the form of landfill or incineration. Simple landfill stacking and incineration have caused great waste of resources and environmental pollution. Waste mushroom sticks are mainly composed of sawdust and residual mushroom roots, which can be used to prepare wood-plastic composite materials after analysis. [0003] The textile industry is closely re...
