Abstract:
PURPOSE: An organic/inorganic composite board producing composition using an acrylic polymer and a geopolymer, and an organic/inorganic composite board are provided to improve the dimensional stability, the hardness, and the lightness of the composite board. CONSTITUTION: An organic/inorganic composite board producing composition contains 100parts of geopolymer by weight and 5~50parts of acrylic polymer by weight. The geopolymer is selected from the group consisting of slag micro-powder, fly ash, paper sludge ash, silica fume, kaolin based minerals, calcium silicate based minerals, calcium aluminate based minerals, plasticized and crushed clay, and oil shale ash. The organic/inorganic composite board producing composition uses an alkali activator as a binder.
Abstract:
The present invention provides a thermoplastic resin composite composition which contains a glass fiber, a wood chip in a pillar shape, and a thermoplastic resin. The wood chip in the pillar shape has at least one flat surface, and includes a needle shape. The average diameter of the glass fiber is 15-17 μm. The thermoplastic resin is one resin selected from the group consisting of polypropylene, polyethylene, polyamide, or a combination thereof.

Abstract:
PURPOSE: A wood polymer composite pavement block is provided to ensure light weight and sufficient rigidity by filling the inside with a different kind of filler. CONSTITUTION: A wood polymer composite pavement block comprises an external cover(10), an internal filler(20), and a hollow unit(25) which is internally equipped in the internal filler. The external cover is composed of a wood polymer composite, and is opened on one side. The internal filler is filled into the external cover, and is composed of a foam-type inorganic material or concrete. The size of the hollow unit inside the internal filler is adjustable in order to lighten the weight.
Abstract:
PURPOSE: A sidewalk block made of synthetic wood is provided to prevent inner filler from cracking by improving the rigidity of the inner filler. CONSTITUTION: A sidewalk block made of synthetic wood comprises an outer cover(10), inner filler(20), and a crack prevention member(30). The outer cover is made of synthetic wood, and one surface is opened. The inside the outer cover is filled with the inner filler. The inner filler is made of an inorganic material. The crack prevention member, composed of a mesh member or glass fiber, is located inside the inner filler and prevents the inner filler from cracking.
