Embodiment Construction

[0017] see figure 1 , which shows the appearance structure of an embodiment of the plastic-wood composite board for packaging steel coils proposed by the present invention. The plastic-wood composite board is composed of a fiber substrate 1 and a plastic layer 2 arranged on the surface of the fiber substrate 1, wherein the plastic layer 2 is composited on the surface of the fiber substrate 1 by casting and calendering methods, and the plastic layer 2 can be composited on the fiber substrate. One surface or both upper and lower surfaces of the substrate 1, figure 1 A structure is shown in which the upper and lower surfaces of the fiber substrate 1 are respectively compounded with plastic layers 2 . The fiber substrate 1 is made of medium density board or hard fiberboard or cardboard or straw fiberboard, the thickness of the fiber substrate 1 is 1.5-6 mm, preferably 4 mm, and the thickness of the plastic layer 2 is 0.2-0.6 mm, preferably is 0.4mm.

Abstract

The invention relates to a plastic-wood composite panel for packaging steel coils and a preparation method thereof. The plastic-wood composite panel is composed of a fiber baseboard and a plastic layer which is compounded by a tape casting method and a calendaring method and arranged on the surface of the fiber baseboard. The preparation method of the plastic-wood composite panel comprises the following steps: firstly fusing and plastifying a plastic material; coating the surface of a fiber baseboard with the plastic material by a tape casting method; calendering the fiber baseboard coated with the plastic material by the use of calender rolls; and cooling and shaping the calendered fiber baseboard by the use of setting rollers so as to prepare the plastic-wood composite panel. The plastic layer of the plastic-wood composite panel is very firm and will not fall off from the fiber baseboard under the action of large external force.

Description

technical field [0001] The invention relates to a plastic-wood composite board for packaging steel coils and a preparation method thereof. Background technique [0002] In the logistics process of coiled steel, because coiled steel is easily oxidized in the natural environment and easily deformed when it is impacted, in order to ensure that the coiled steel is not eroded by the external environment and damaged by impact, it is necessary to use packaging components to protect the surface of the coiled steel. for packaging. As we all know, the components used for packaging coiled steel are composed of outer guards, inner guards, and end guards, and the packaging components should not only have certain rigidity and strength, but also have certain flexibility and corrosion resistance; Another problem is that coiled steel is the basic material of the national economy, and its output is very large, resulting in a very large amount of components for packaging coiled steel, and at ...
