【摘要】 本文通过试验研究了高白填料氢铝、钙粉及高白填料氢铝与钙粉混合料所制作的人造石板材性能的差异。结果表明,添加了四种不同填料(高白填料氢铝(1#AH、2#AH)、钙粉、高白填料氢铝与钙粉混合料(6:4))所制作的人造石板材在以下性能方面存在明显差异:①2#AH人造石专用料与树脂的混合粘度最低(15900cP),钙粉与树脂混合粘度最高(18500cP);②用钙粉作填料制作的人造石板材透光性很低,在钙粉中加入高白填料氢铝后可使人造石板材的透光性明显提高,但是钙粉板的白度较高(L值=82.76);③在弯曲性能上,高白填料氢铝板材明显优于钙粉板;④在阻燃性能方面,高白填料氢铝(1#AH、2#AH)制作的人造石板材的氧指数分别达到43和42.5,钙粉板的氧指数仅为25,加钙粉量为40%的钙粉与高白填料氢铝的混合料制作的人造石板材的氧指数为31。而在拉伸性能、硬度、冲击性能方面相差不大;在耐污性能有所不同,钙粉板对口红的耐污性较好,氢铝、氢铝与钙粉混合料制作的人造石板材对醋和酱油的耐污性比较好。更多还原

【Abstract】 This paper studied properties differentials of the man-made sheets made of high whiteness aluminum hydroxide filler(high whiteness AH),calcium and their blends.The results showed,man-made sheets with four different fillers(high whiteness AH(1# AH,2# AH),calcium powder and their blends(6: 4)),have the obvious differences in the following properties:① The adhesive mixed 2# AH with resin is the lowest(15900cp),the highest adhesive is blending calcium powder with resin(18500cp);② The light transmission of with calcium powder fillers,but putting high whiteness AH into calcium power can improve light transmission,meanwhile,the sheets have higher whiteness(L=82.76);③For the flexure properties,AH sheets are better than calcium powder sheets;④For flame retardant,the oxygen index of the man-made sheets with 1# AH,2# AH fillers is separately 43 and 42.5,calcium sheets 25,the sheets with 40% calcium powder and AH filler 31.In addition,their tensile,rigid,impact properties are similar.更多还原
