植物纖維20、乙烯醋酸乙烯共聚物30、碳酸鈣40、發泡劑50以及架橋劑60經過密閉式捏合機70攪拌後，也可以再放到一滾輪機(未繪示)反覆滾壓攪拌配方，使分散效果更佳。之後再通過一出片機(未繪示)壓成所需規格的片狀體再放到熱壓發泡機80進行加熱及加壓發泡，可以使每一個發泡氣泡孔12形成獨立氣泡孔。The plant fiber 20, the ethylene vinyl acetate copolymer 30, the calcium carbonate 40, the foaming agent 50, and the bridging agent 60 are stirred by the closed kneading machine 70, and then can be placed on a roller machine (not shown) to be repeatedly rolled and stirred. To make the dispersion better. Then, it is pressed into a sheet body of a desired specification by a filming machine (not shown) and then placed in a hot press foaming machine 80 for heating and pressure foaming, so that each of the foamed cells 12 can be formed into independent bubbles. hole.
通過以上說明，本創作藉由包含植物纖維20、乙烯醋酸乙烯共聚物30及碳酸鈣40等材料，混合發泡劑50與架橋劑60後放到密閉式捏合機70進行攪拌，再放進熱壓發泡機80的模具中加溫加壓模塑形成板片材料，該植物纖維發泡板10的結構中具有許多發泡氣泡孔12，該些發泡氣泡孔12為彼此之間不連通的獨立氣泡孔，使本創作能提供一種能自然分解、能具有更大彈性以及更佳隔音效果的植物纖維發泡板結構。By the above description, the present invention comprises mixing the foaming agent 50 and the bridging agent 60 with a material such as plant fiber 20, ethylene vinyl acetate copolymer 30, and calcium carbonate 40, and then putting it into a closed kneader 70 for stirring, and then putting in heat. The mold of the pressure foaming machine 80 is heated and pressure molded to form a sheet material, and the plant fiber foamed sheet 10 has a plurality of foamed cells 12 in the structure, and the foamed cells 12 are not connected to each other. The independent bubble holes enable the creation of a plant fiber foam board structure that is naturally decomposable, has greater elasticity and better sound insulation.
