Problems solved by technology

With the increasing awareness of environmental protection worldwide, it is of great significance how to use some discarded and waste materials to make materials that replace wood. For example, various laminate floorings that have been widely used now use sawdust to bond The high-strength floor made of chemical agent, although it can replace wood to a certain extent, but its processing performance is poor
Extensive searches have been carried out for the above problems, but no technical solutions related to the present invention have been found

example 1

[0016] 1. Raw materials: 50 kg of polyethylene, 30 kg of peanut shells, 18 kg of sawdust, 1 kg of cross-linking agent, and 1 kg of coupling agent.

[0017] 2. Production process and technology: polyethylene, peanut shells and sawdust are cleaned, cleaned, cooled and dried. Use LYPC-1000 pulverizer to pulverize the above items, add crosslinking agent and coupling agent to SJz65 / 132M twin-screw extruder, mix, heat to 180°C and extrude to obtain the new wood-plastic material of the present invention.

example 2

[0019] 1. Raw materials: 30 kg of polyethylene, 30 kg of polypropylene, 20 kg of peanut shells, 10 kg of straw, 8 kg of sawdust, 1 kg of cross-linking agent, and 1 kg of coupling agent.

[0020] 2. Production process and technology: polyethylene, polypropylene, straw, peanuts, shell sawdust are cleaned, cleaned, cooled and dried. Use LYPc-1000 pulverizer to pulverize the above items. Add cross-linking agent and coupling agent to SJz65 / 132M twin-screw extruder, mix, heat to 185°C, and then extrude to obtain the new wood-plastic material of the present invention.

example 3

[0022] 1. Raw materials: 20 kg of polyethylene, 20 kg of polypropylene, 20 kg of peanut shells, 10 kg of straw, 10 kg of plant rhizomes, 18 kg of sawdust, 1.5 kg of cross-linking agent, and 0.5 kg of coupling agent.

[0023] 2. Production process and technology: polyethylene, polypropylene, straw, peanut shells, plant roots, and sawdust are cleaned, cleaned, cooled, and dried. Use LYPC-1000 pulverizer to pulverize the above items. Add cross-linking agent and coupling agent to SJz65 / 132M twin-screw extruder, mix, heat to 190°C, and then extrude to obtain the new wood-plastic material of the present invention.

Abstract

The present invention relates to one kind of wood-plastic material and its production process. The wood-plastic material consists of plastic 29-70 wt%, wood fiber 28-69 wt%, cross-linking agent 1-2 wt%, and coupling agent 1-2 wt%. The plastic may be high pressure polyethylene, low pressure polyethylene, non-toxic polyvinyl chloride and polypropylene; and the wood fiber may be plant root, branch, leaf, bark, peanut shell, wheat straw and sawdust. Its production process includes the following steps: 1. washing waste plastic and wood fiber, stoving and crushing; and 2. heating to 160-200 deg.c in an extruder and extruding to form plate and other shaped material. The wood-plastic material has the advantages of non-solubility, high ageing resistance, good machinability, etc and may be used to replace wood, steel and non-ferrous metal. The production process has waste utilized.

Description

Technical field: [0001] The invention relates to a new material and a production method thereof, in particular to a new material which can replace wood and steel. Background technique: [0002] As the main material of construction and furniture, wood has been widely used in large quantities, but with the gradual reduction of forest resources, wood is becoming more and more scarce. With the increasing awareness of environmental protection worldwide, it is of great significance how to use some discarded and waste materials to make materials that replace wood. For example, various laminate floorings that have been widely used now use sawdust to bond Although it can replace wood to a certain extent, its processing performance is poor. Extensive searches have been carried out for the above problems, but no technical solutions related to the present invention have been found. Invention content: [0003] One of the purposes of the present invention is to provide a new material ...
