Abstract

The invention provides a preparation method of anti-tensile nano SiO2-high density polyethylene-lignocellulose fiber composite plastic, aiming at solving the problems that polyethylene has poor impactresistance, is easy to age and easily becomes brittle at low temperature. The preparation method comprises the following steps: firstly, preparing bagasse ash and rice husk ash by utilizing a high-temperature furnace; then uniformly mixing the bagasse ash, the rice husk ash, nano silicon dioxide, high density polyethylene and maleic anhydride grafted polyethylene, and adding into an extruding machine; carrying out injection molding to obtain a nano SiO2-high density polyethylene-lignocellulose fiber compound; finally, uniformly mixing the nano SiO2-high density polyethylene-lignocellulose fiber compound, a natural plasticizer and a thermal stabilizer, and then heating, smelting and cooling to obtain the anti-tensile nano SiO2-high density polyethylene-lignocellulose fiber composite plastic. The plastic provided by the invention has good impact resistance and anti-tensile performance and can be widely applied to preparation of neck rings of shampoo and bath gel packaging bottles.

Description

technical field [0001] The invention relates to the field of plastic manufacturing, more specifically, the invention relates to a preparation method of anti-stretch nanometer SiO2-high-density polyethylene-lignocellulose fiber composite plastic. Background technique [0002] With the rapid development of my country's economy, the plastics industry has also achieved rapid development. Polyethylene is a typical thermoplastic with excellent low temperature resistance, good chemical stability, and can withstand most acid and alkali erosion. At present, polyethylene has been widely used in the preparation of packaging materials for various chemical products. However, polyethylene has poor impact resistance, is easy to age, and is easy to become brittle at low temperature, which makes it difficult for materials made of polyethylene to be used in the interface collar of packaging bottles. Shampoo and shower gel are essential daily chemicals in people's life. Due to frequent use, ...
