Thermal insulation bamboo weaving sheet from wood sawdust/natural rubber composites

Abstract

The objective of this research was to study the production in thermal insulation bamboo weaving sheet from wood sawdust/natural rubber composites, which the combined sawdust rubber wood and latex next to covering the bamboo sheets, on the top and back side as sandwiched. The latex was reinforced between sawdust rubber wood, and bamboo sheet. The sheet dimension was 30x30x1 cm by compression molding. The ration of composites (latex: sawdust rubber wood) composed 5 ratios: RS20 (20: 100) RS24 (24: 100) RS28 (28: 100) RS32 (32: 100), and RS36 (36: 100) were studied. The results showed that the RS28, RS32, and RS24 showed the maximum force loading capacity 3,724 N 3,128 N and 3,112 N respectively. While, the RS32 RS36 and RS24 presented swelling in thickness after immersion in water of 7.15 6.82 and 6.76 respectively. The thermal properties showed that thermal conductivity of RS20 (0.076 w/m·k), RS28 (0.077 w/m·k) and RS36 (0.077 w/m·k).

As, thermal resistance of 0.166 m².K /W, 0.174 m².K/W, and 0.172 m².K /W, respectively. It was found that 3 ratio of thermal insulation bamboo weaving sheet from wood sawdust/natural rubber composites passed JIS A 5908: 2003 Type 8 (Insulation Board) standard. From the research, the thermal insulation bamboo weaving sheet from wood sawdust/natural rubber composites, can be applied as a guideline for producing prototypes wall panels to produce environmentally friendly products. The production cost is 370 baht/m²
