Title:
BIOLOGICAL FORMALDEHYDE-FREE ADHESIVE, BIOLOGICAL COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/284729
Kind Code:
A1
Abstract:
Disclosed are a biological formaldehyde-free adhesive, a biological composite material and a preparation method therefor, which relate to the technical field of formaldehyde-free adhesive preparation. The method comprises: performing solid-liquid separation on vinasse, extracting supernatant from the liquid part, and then concentrating to obtain a biological formaldehyde-free adhesive. The vinasse is subject to solid-liquid separation by using separation and extraction technology, and the liquid part of the vinasse containing a large amount of aqueous protein is extracted and concentrated to produce a natural biological formaldehyde-free adhesive. The preparation process for the biological formaldehyde-free adhesive odes not require a crushing and drying process, and the separated liquid part containing the aqueous protein can be directly concentrated to obtain the biological formaldehyde-free adhesive. The biological formaldehyde-free adhesive has good adhesiveness, good water resistance, low costs, and high solid content, and is easy to be widely promote on manmade boards. Since the raw material is a biological fermentation byproduct, the raw material itself is low-carbon, environmentally friendly and sustainable, which has important economic and social benefits for conserving energy and reducing emissions of manmade boards and the entire industrial chain.
