Rear earth solution-glass fiber compounded bamboo material modification treatment method

Abstract

The invention discloses a rear earth solution-glass fiber compounded bamboo material modification treatment method. The rear earth solution-glass fiber compounded bamboo material modification treatment method comprises preparing silane coupling agent KH550 and absolute ethylene alcohol into a solution, uniformly mixing nanosilicon dioxide and chitosan, then uniformly spraying the mixture onto bamboo material samples, and naturally drying the bamboo material samples; processing the preprocessed bamboo materials in vacuum inside a vacuum drying vessel for absorbing crosslinking polymer processing liquid, then extracting and drying the processed bamboo materials to constant weight, and then heating the dried bamboo materials to an oven dry state; soaking the bamboo materials into plasticizer,placing the soaked bamboo materials inside a processing tank, vacuumizing the processing tank, inletting nitrogen for pressurizing, holding the pressure and then depressurizing the processing tank, continuing to soak the bamboo materials, heating the bamboo materials for solidification, reducing the temperature, heating and drying the solidified bamboo materials to an oven dry state, and coolingthe bamboo materials down; uniformly mixing a rear earth solution modifier with KH570 modified glass fiber to obtain a compound modifier, and soaking the plasticized and modified bamboo materials formodification, and performing washing and then drying the modified bamboo materials in a drying oven.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a method for compounding and modifying bamboo with a rare earth solution-glass fiber. Background technique [0002] The types of bamboo in my country, the area of ​​bamboo forests and the output all rank first in the world. Bamboo is considered to be the most potential plant resource in the 21st century. However, due to the higher content of non-cell wall substances in bamboo such as starch, reducing sugar, protein, fat, etc. than wood, it is easy to rot, mildew and insects when used in warm and humid conditions. These shortcomings greatly shorten the service life of bamboo. And limited the scope of application of bamboo powder. Contents of the invention [0003] The object of the present invention is to solve the existing problems and provide a method for treating bamboo with rare earth solution-glass fiber composite modification. The treated bamboo prepared acc...
