一种稻壳纤维合成树脂粉及稻壳纤维产品的制作工艺 技术领域
本发明涉及化工材料领域， 具体涉及的是一种稻壳纤维合成树脂粉及稻壳 纤维产品的制作工艺。 背景技术
现有市面上的餐具、 家具、 厨具等生活用品均采用塑料、 木、 竹等产品， 此类产品成本高、 不能降解、 不环保， 其中塑料不仅不能降解， 被公认为 "白 色污染"， 而且破坏土壤的透水性， 而木类产品要砍伐森林， 制造过程中有废水 污染， 并不是很好的环保材料。
特别是现有的一次性餐具大多数使用的是发泡塑料， 其发泡剂为氟利昂， 该氟利昂会破坏大气的臭氧层， 而且它极难降解， 发明专利公报 CN1212312A公 开了一种可降解的一次性餐具及其制造方法， 该方法采用农作物壳或杆为原料， 加入脲醛树脂和三聚氰胺等热压制成， 该方法所采用的三聚氰胺价格昂贵， 而 且在降解后该物质还会造成环境污染。
中国是世界上第一产稻大国，年产量约 1. 95亿吨，占全国粮食总产量的 40%， 占世界稻谷总产量的 37%, 每年稻壳的剥离量达数千万吨， 稻壳本身是一种农业 废料， 它在广大农村只用作燃料、 饲料填充物， 长期以来， 由于对稻壳的利用 处于落后状态， 造成了稻壳资源的极大浪费。
目前， 世界上经济发达国家对稻壳的深度开发应用领域相当广泛， 除了直 接可作为食用菌的培养基料、 用作能源发电、 美容化妆品等诸多食品、 化工用 品， 但上述稻壳的利用大多是经过复杂的工艺过程， 改变了稻壳的性质， 使其 变为新的生成物来加以利用， 直接加工利用稻壳的方法实在稀少， 为稻壳找到
