High-toughness quartzite plate and preparation method thereof
The invention discloses a high-toughness quartzite plate and a preparation method thereof. The high-toughness quartzite plate comprises the following components in parts by weight: 47-63 parts of an inorganic material, 12-15 parts of unsaturated polyester resin, 5-11 parts of a toughening aid, 1-2 parts of an accelerant, 1-5 parts of a curing agent and 1-2 parts of a silane coupling agent. The toughening aid is prepared by compounding modified tetrapod-like zinc oxide whiskers, dibutyl phthalate, carbon fiber powder and polyester fibers, and the modified tetrapod-like zinc oxide whiskers, the silane coupling agent and the like act together, so that the compatibility with unsaturated polyester resin and other components is improved; by adding the dibutyl phthalate, the carbon fiber powder and the polyester fiber, the filling compactness among the raw materials is improved, so that the mechanical property of the quartz stone plate is further improved, the toughness of the quartz stone plate is improved, and the quartz stone plate is prevented from cracking and deforming.
本发明公开了一种高韧性石英石板材及其制备方法，所述高韧性石英石板材按重量份计包括：无机材料47~63份、不饱和聚酯树脂12~15份、增韧助剂5~11份、促进剂1~2份、固化剂1~5份、硅烷偶联剂1~2份。本发明中的增韧助剂由改性四针状氧化锌晶须、邻苯二甲酸二丁酯、碳纤维粉、聚酯纤维复配而成，改性四针状氧化锌晶须与硅烷偶联剂等共同作用提高了与不饱和聚酯树脂等成分的相容性，邻苯二甲酸二丁酯、碳纤维粉、聚酯纤维的添加改进了原料之间的填充紧密度，使得石英石板材的力学性能得到进一步提升，从而改善石英石板材的韧性，防止石英石板材开裂、变形。
