Polypropylene wood-plastic slab and preparation method thereof

Abstract

The invention relates to a polypropylene wood-plastic plank and a preparation method thereof. The preparation method comprises the following steps: using polypropylene resin, wood meal, graft, fluidity modifier, coupling agent, activating agent, stuffing, anti-mushing agent and pigment as a formulation; adding the raw materials into a mixer according to the proportion to mix evenly, then inputting the prepared mixed raw materials into a laminator, automatically controlling a heating process, and extruding the raw materials to produce the plank by internal process flows. The preparation methodhas the advantages of simple processes, convenient operation, and good interface combining property and properties of essential recombination products, can meet processing fluidity requirement of finished products, and has a little amount of used plastic. The finished products have good stability, large strength, impact resistance, no easy combustion, natural essence feel, and safe use, can obtain required automotive upholstery through vacuum blowing operation and mold forming, and have favorable application value and wide popularization and application prospects.

Description

technical field [0001] The invention relates to the manufacturing technology of plastic boards, in particular to the manufacturing technology of wood-plastic boards for automotive interior parts. Background technique [0002] At present, the domestic automotive interior parts and building materials industries use a large number of hard plastic materials. Because plastics have good strength, hardness and toughness, and are easy to shape, their application range is becoming wider and wider. The production process of domestic polymer composite wood-plastic materials is mostly based on a two-step method, that is, first granulating and forming through a granulator, and then mold extrusion processing. As a derivative of petroleum, plastics, with the decreasing petroleum resources, increasing demand for plastics and relatively higher functional requirements for plastics, the original plastic materials can no longer meet market needs. At the same time, the existing plastic manufact...

As a derivative of petroleum, plastics, with the decreasing petroleum resources, the increasing demand for plastics and the relative increase in the functional requirements of plastics, the original plastic materials can no longer meet the needs of the market

At the same time, the existing plastic manufacturing technology has problems such as non-adjustable processing fluidity, poor compatibility and interfacial bonding and penetration, and failure to consider the improvement of mechanical properties, which has become a difficulty restricting wood-plastic processing.
