【摘要】：通过搓磨分丝和高浓磨浆工艺技术制得稻草、桉木、竹机械浆,再分别和蔗渣化学浆混合制备模塑墙体装饰材料。研究了稻草、桉木、竹机械浆的添加对模塑墙体装饰材料的抗张强度、耐破度、挺度、外观颜色等物理性能的影响。研究表明:桉木、稻草机械浆添加量分别为20%和30%(均为质量分数)时其抗张指数值最大,比未添加机械浆的分别提高了50.35%和54.15%;桉木、稻草机械浆添加量分别为30%和30%时其挺度值最大,比未添加机械浆的分别提高了52.76%和63.41%;竹机械浆添加量为5%时其耐破指数值最大,比未添加竹机械浆的提高了36.56%;机械浆的添加可以较为明显地改善墙体装饰材料的外观颜色,使其更接近自然色。
[Abstract]:Straw, eucalyptus and bamboo mechanical pulp were prepared by twisting and separating silk and high consistency pulp, and then mixed with bagasse chemical pulp to prepare molded wall decoration material. The effects of straw, eucalyptus and bamboo mechanical pulp on the tensile strength, breaking resistance, stiffness, appearance color and other physical properties of molded wall decoration materials were studied. The results showed that the tensile index of eucalyptus and straw were 20% and 30% (mass fraction) respectively, which were 50.35% and 54.15% higher than those without mechanical pulp. The maximum stiffness of Eucalyptus and straw mechanical pulp was increased by 52.76% and 63.41% than that of unadded mechanical pulp at 30% and 30%, respectively. When the addition of bamboo mechanical pulp is 5, its breaking resistance index is the largest, which is 36.56 higher than that without bamboo mechanical pulp, and the addition of mechanical pulp can obviously improve the appearance color of wall decoration material and make it closer to the natural color.
