Description
技术领域
本发明主要涉及一种复合型材，尤其涉及一种高耐水木塑复合材料。
背景技术
木塑复合材料内含塑料和纤维，因此，具有同木材相类似的加工性能，可锯、可钉、可刨，使用木工器具即可完成，且握钉力明显优于其他合成材料。机械性能优于木质材料。握钉力一般是木材的3倍，是刨花板的5倍。
木塑复合材料内含塑料，因而具有较好的弹性模量。此外，由于内含纤维并经与塑料充分混合，因而具有与硬木相当的抗压、抗弯曲等物理机械性能，并且其耐用性明显优于普通木质材料。表面硬度高，一般是木材的2——5倍。
木塑材料及其产品与木材相比，可抗强酸碱、耐水、耐腐蚀，并且不繁殖细菌，不易被虫蛀、不长真菌。使用寿命长，可达50年以上。
通过助剂，塑料可以发生聚合、发泡、固化、改性等改变，从而改变木塑材料的密度、强度等特性，还可以达到抗老化、防静电、阻燃等特殊要求。
具有紫外线光稳定性、着色性良好。其最大优点就是变废为宝，并可100%回收再生产。
可以分解，不会造成“白色污染”，是真正的绿色环保产品。
原料来源广泛，生产木塑复合材料的塑料原料主要是高密度聚乙烯或聚丙烯，木质纤维可以是木粉、谷糠或木纤维，另外还需要少量添加剂和其他加工助剂。还可以根据需要，制成任意形状和尺寸大小。
发明内容

聚丙烯树脂粒子60-70、木质纤维50-60、聚癸二酸酐2-3、超细硫酸钡粉4-5、海泡石粉2-3、3-缩水甘油醚氧基丙基三甲氧基硅烷1-2、二盐基亚磷酸铅1-2、霍霍巴油1-2、二甲基环己胺1-2、改性增塑剂3-4；
所述的改性增塑剂是由下述重量份的原料组成的：
地沟油30-40、邻苯二甲酸酯20-30、蓖麻油5-6、霍霍巴油2-3、γ-氨丙基三乙氧基硅烷1-2、纳米氮化铝粉0.2-0.3、萜烯树脂1-2、过氧化二叔丁基0.1-0.2、异辛酸0.1-0.2；
将上述萜烯树脂加热到80-100℃，保温10-15分钟，降低温度为50-60℃，加入γ-氨丙基三乙氧基硅烷，搅拌分散3-5分钟，依次加入邻苯二甲酸酯、地沟油、蓖麻油、霍霍巴油，添加完毕后，升高温度为90-100℃，充分搅拌，加入纳米氮化铝粉、异辛酸，继续升高温度为105-110℃，滴加过氧化二叔丁基，搅拌反应1-2小时，冷却至常温，即得所述改性增塑剂。
一种高耐水木塑复合材料的制备方法，包括以下步骤：
将上述木质纤维与超细硫酸钡粉、海泡石粉混合，100-120℃下搅拌加热10-15分钟，降低温度为60-65℃，加入3-缩水甘油醚氧基丙基三甲氧基硅烷，800-1000转/分搅拌分散3-5分钟，冷却至常温，加入剩余各原料，充分混合，通过双螺杆挤出机熔融共混挤出，成型，即得所述高耐水木塑复合材料。
本发明的优点是：
本发明的木塑复合材料力学性能优越，吸水率低，尺寸稳定性好，加入的改性增塑剂进一步提高了树脂粒子和木质纤维的相容性，提高了成品的综合性能。
