Abstract

The invention relates to a method used nanometer material to modify rape stalk, twin screw extruding technology to make new type green decorating or packing material which is formed by rape stalk, nanometer silicon dioxide, double amino silane, sodium trimetaphosphate, high density polyethylene, azo bis formamide, French chalk, paraffin, chlorinated polyethylene, and ethylene propylene terpolymer. The modifying and molding for the rape stalk is in the same device and technology. It is detected that the main technical criteria of the decorating material are that bending strength 27.4MPa, elastic modulus in bending 1582MPa; surface cigarette igniting resistance are that no yellow spot, black spot, crack, bubbling; it satisfies our country relative standard, can substitute for parts of plastic and wood products.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of crop by-products, and relates to the technical field of using crop straws to prepare building decoration or packaging materials. Specifically, the invention relates to modifying rapeseed stalks by using nanometer materials, and adopting a twin-screw extrusion process and equipment to complete the modification and molding of rapeseed stalks at one time. The invention also relates to methods of preparing the material. Background technique [0002] As we all know, my country is a big producer of wood and wood products in the world, and it is also a big consumer. At the same time, it is a country with very little forest resources per capita. In addition to deforestation, the forest area in our country is decreasing year by year. The reduction of forest and surface vegetation will not only lead to the degradation of cultivated land and climate change, but also have a serious impac...
