Produce strong coupling enables interfacial bonding between the plastic and composite pontoon deckingflour surface; at the same time to reduce the water absorption of wood flour, wood flour and plastic to improve compatibility and dispersion, so that the mechanical properties of the composites increased significantly. Common coupling agents are: isocyanates, dicumyl peroxide, aluminum esters, phthalate esters, silane coupling agent, a maleic anhydride-modified polypropylene agent (MAN-g-PP), ethylene - acrylate (EAA). 1wt% ~ 8wt% wood flour addition amount is generally added in an amount of wood plastic decking, such as silane coupling agents can improve adhesion plastic and wood powder, wood powder to improve dispersibility, reduced water absorption, and with an alkaline treated wood meal can only improve the dispersibility of the wood powder, wood flour does not improve its water-absorbing plastic adhesion. It should be noted that the maleate salt of stearic acid coupling and repulsion lubricant will react when used together resulting in product quality and yield.
Plasticizer for some high glass environmentally friendly wall board temperature and the melt flow viscosity of the resin, such as the hardness of PVC, with the wood flour composite processing difficulties, often need to add a plasticizer to improve its workability. Plasticizers molecular structure containing both polar and nonpolar gene, under high temperature shear, which can enter the polymer molecular chain, attract each other by a uniform polarity genes stabilizing system,
