preparation example Construction

[0064] The preparation method of the adopted nano-bamboo powder is as follows: the natural bamboo and bamboo chips are first impregnated in an alkaline solution, then the fibers are softened after 1-10 days, then ground by a high-speed grinder, and then filtered through an 80-mesh filter screen, and then Dry, remove the water, and grind again into 100-500nm ultrafine powder by nano-grinding equipment.

[0065] The preparation method of the nano-bamboo charcoal powder used is as follows: natural bamboo is first dried, then calcined at high temperature and high pressure to become bamboo charcoal, then ground by a high-speed grinder, filtered through an 80-mesh filter, and ground again into 100- 500nm ultrafine powder.

Abstract

The invention relates to the artificial leather field, and concretely relates to a preparation method for synthesizing artificial leather by nano bamboo charcoal UV. The artificial leather is prepared by polyurethane and nano bamboo powder or nano bamboo charcoal powder. The artificial leather has the advantages of simple process, emission reduction and energy saving environmental protection, excellent function, chemical resistance, antibiosis and disinfection.

Description

technical field [0001] The invention relates to the field of artificial leather, in particular to a preparation method of nano bamboo carbon PU synthetic artificial leather. Background technique [0002] Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural characteristics. However, with the growth of the world population, the human demand for leather has doubled, and the limited amount of natural leather has long been unable to meet this demand. In order to solve this contradiction, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the deficiency of natural leather. The research history of more than 50 years is the process of artificial leather and synthetic leather challenging natural leather. Scientists started from the research and analysis of the chemical composition and organizational structure of natural leather, started from nitrocellulose ...
