Embodiment Construction

[0010] A kind of production technology of recycled plate, is characterized in that, comprises the steps:

[0011] 1) Mix polymer materials, crop fiber powder, modifiers and auxiliary additives to form a mixture.

[0012] Among them, the polymer material is various plastics, such as PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride) or ABS resin. The crop fiber powder can also be sawdust powder or bamboo fiber powder.

[0013] 2) Add the mixture to the heating unit.

[0014] The heating device is an internal mixer, and an internal mixer is a heating device commonly used in the chemical industry.

[0015] 3) Start the heating device to heat the mixture of the polymer material and the crop fiber powder so as to melt the polymer material.

[0016] In general, when the temperature rises to 175°C, the polymer material can be melted, and the moisture content in the mixture is reduced, which reduces the impact on the physical properties of the produced board and other ...

Abstract

The invention relates to a process for producing regenerated plates, which is characterized in that the process comprises the following steps: 1) mixing polymer materials, crop fiber powder, a modifier and adjuvant additives, and forming a mixture; 2) adding the mixture into a heating device; 3) starting the heating device; 4) smashing the high-temperature mixture, and then sending into a material tube of a single-screw extruder; 5) sending the high-temperature mixture into the material tube of the single-screw extruder; and 6) using the single-screw extruder to extrude the mixture into a mold, carrying out extrusion molding treatment, and then forming the regenerated plates with special shapes. The process has the advantages that the regenerated plates produced by the production process have high hardness and strength, acid and alkali resistance, corrosion resistance, no formaldehyde, difficult deformation, moth proofing property, low cost and good elasticity.

Description

technical field [0001] The invention relates to a production process of recycled boards. Background technique [0002] In the prior art, boards such as floor boards and wall boards are generally made of wood. At present, wood is less and less, and the price of wood is getting higher and higher, and the price of wooden floor boards is also very high. The existing wooden board technology has high requirements on the quality of the wood, and the leftovers of many wood walls cannot be fully utilized, resulting in huge waste. Although composite board technology can make small pieces of wood into composite boards, its quality cannot be compared with real wooden boards, and a large amount of glue is needed in the processing process, such as urea-formaldehyde gum, which will produce toxic gases such as formaldehyde, affecting human health. At the same time, the industrial waste or domestic waste produced by various countries every year contains a large amount of plastics that are ...
