Abstract
The invention discloses a PP-based flame-retardant wood-plastic composite board and a preparation method thereof. The PP-based flame-retardant wood-plastic composite board is composed of, by weight, 25-45 parts of PP, 45-70 parts of wood powder, 0.5-1.5 parts of coupling agent, 0.1-0.5 part of antioxidant, 0.1-0.5 part of lubricant, 0.2-1.0 part of dispesant and 0.5-3 parts of flame retardant. The preparation method includes following steps: fully mixing PP, the wood powder, the coupling agent, the antioxidant, the lubricant, the dispersant and the flame retardant; forming the wood-plastic composite board through extrusion or hot pressing. The PP-based flame-retardant wood-plastic composite board has dual properties of wood and PP plastic and has good flame-retardant effect.
Description
Technical field
The present invention relates to a kind of PP base flame-retardant wood-plastic composite board and preparation method thereof, belong to composite wood board technical field.
Background technology
Wood plastic composite is a kind of novel composite, with the wood fiber for reinforcing material, matrix material can be thermosetting plastics and thermoplastic, such as polyethylene (PE), polypropylene (PP), polrvinyl chloride (PVC), ABS resin and polystyrene (PS) etc., front 3 kinds most widely used general.Wood plastic composite combines the advantage of timber and plastics, good stability of the dimension, corrosion-resistant, resistance to damage by worms, ageing-resistant, and recyclable recycling.Wood plastic composite adopts wood machining residues (wood flour, wood shavings etc.) and waste or used plastics to be raw material production, and combination property highlights and remarkable in economical benefits.But owing to wood plastic composite easily burns, and the field that it is applied has the right requirement of resistance mostly, therefore give the needs that the good fire resistance of wood plastic composite is the development of this materials application.Wood plastic composite fire-retardant sufficiently complex, relates to fire-retarding of wood and plastic flame and the INTERACTION PROBLEMS of the two.At present, both at home and abroad still it is in for wood plastic composite flame treatment research the starting stage, based on the advanced achievements of fire-retarding of wood and plastic flame and correlation experience, is generally adopted the means that wood powder or the wood fiber and matrix is fire-retardant respectively.
