Embodiment

[0054] Table 2 shows the ingredients for preparing the coated reinforced biofiber and the WPC of the present invention.

[0055]

[0056] Mix the pre-dried wood fibers into the plastisol as follows:

[0057] In a laboratory-scale Henschel mixer, plastisol was added to pre-dried wood fibers, and then mixed at 700 rpm using a 3-blade disperser equipped with 21 cm diameter blades. After mixing the liquid ingredients for 3-5 minutes at ambient temperature, the batch is complete. In the mixer, heat is slightly generated due to shear mixing, but when the mixing is completed, the coated reinforcing fiber is not hot. The resulting coated reinforced biofiber is non-agglomerated and maintains the overall light yellow appearance of the wood fiber itself. What is striking is that the bio-fiber is only coated on the outer surface and not penetrated by the plastisol, such as figure 1 As shown, the figure is a cross-sectional photograph of the coated reinforced biofiber of Example 2 at a resolu...

Abstract

Coated reinforcing biofiber for thermoplastic articles is disclosed. The coating on the biofiber comprises a plastisol. The coated reinforcing biofiber can be used in thermoplastic compounds to simulate the appearance of natural wood while adding significantly increased flexural modulus for the wood plastic composite (WPC).

Description

[0001] Priority statement [0002] This application claims the priority of US Provisional Patent Application Serial No. 61 / 308165 filed on February 25, 2010 with Attorney File No. 12010004, which is incorporated herein by reference. Invention field [0003] The present invention relates to the use of plastisol to coat biofibers for plastic products. technical background [0004] In many industries, plastics have replaced other materials. In the packaging industry, plastic replaces glass to minimize breakage, reduce weight, and reduce energy consumption in manufacturing and transportation. In other industries, plastics replace metals to minimize corrosion, reduce weight, and provide color-in-bulk products. Recently, a whole industry called "wood polymer composite" (WPC) has emerged. [0005] The basis of wood-plastic composites lies in the following premise. The use of wood fibers and other naturally occurring microparticles and other biological fibers as additives for thermoplastic...
