【摘要】：以厚度為0.35～0.40 mm的櫸木為薄木基材、棉網(wǎng)格布為增強材料和PES(聚醚砜)型HMA(熱熔膠)為膠粘劑,選用BL-環(huán)保阻燃劑制備裝飾材料用阻燃柔性復(fù)合薄木;然后以拉伸強度、剝離強力和表觀性能為衡量指標,以熱壓壓力、熱壓溫度、含水率和膠膜厚度為試驗因素,采用正交試驗法優(yōu)選制備柔性復(fù)合薄木的最優(yōu)方案。結(jié)果表明:以PES型HMA作為薄木/棉網(wǎng)格布復(fù)合用環(huán)保型膠粘劑,其不僅與BL-環(huán)保阻燃劑有很好的相容性,而且可避免脲醛樹脂膠粘劑的甲醛釋放等問題;增強型薄木與非增強型薄木相比,前者的橫紋拉伸強度顯著提高,并且前者不再表現(xiàn)為脆性特征;柔性復(fù)合薄木熱壓工藝條件的最優(yōu)方案為熱壓壓力0.7 MPa、熱壓溫度125℃、含水率12%和膠膜厚度0.10 mm。
[Abstract]:The flame-retardant flexible laminated wood for decorative materials was prepared by using beech with thickness of 0.35 ~ 0.40 mm as thin wood substrate, cotton web cloth as reinforcing material and PES (polyether sulfone) type HMA (hot-melt adhesive) as adhesive, and then with tensile strength. The peeling strength and apparent performance were taken as the measurement index, and the optimum scheme of preparing flexible composite thin wood was selected by orthogonal test, taking hot pressing pressure, hot pressing temperature, moisture content and film thickness as experimental factors. The results show that using PES type HMA as the compound environmental protection adhesive for thin wood / cotton web cloth not only has good compatibility with BL- environmental protection flame retardant, but also can avoid formaldehyde release from UF resin adhesive. The transverse tensile strength of the enhanced thin wood is significantly higher than that of the non-enhanced thin wood, and the former is no longer brittle, and the optimum processing conditions of the flexible composite thin wood are as follows: the hot pressing pressure is 0.7 MPa, and the hot pressing temperature is 125 鈩，
