Abstract

The invention discloses a soybean formaldehyde-free adhesive and a preparation method thereof. The adhesive is prepared from 27-33 parts of degreased protein powder, 1-2 parts of denaturant, 0.5-2.0 parts of emulsifier, 5-15 parts of reinforcing agent and 65-73 parts of dispersing medium. The preparation method comprises the steps of carrying out dispersion, carrying out ultrasonic treatment, carrying out heating, carrying out stirring, and the like. The formaldehyde-free adhesive and the preparation method thereof have the advantages that the requirements of adhesives for artificial boards on water resistance can be met, and the practicability of protein adhesives is guaranteed; the problem of formaldehyde pollution to indoor air caused by the artificial boards is thoroughly solved; main raw materials are renewable resources, so that the formaldehyde-free adhesive and the preparation method thereof are in line with environmental protection and sustainable development principles.

Description

technical field [0001] The invention relates to a wood adhesive and a preparation method thereof, in particular to an formaldehyde-free soybean protein-based adhesive for multi-layer solid wood composite flooring and a preparation method thereof, belonging to the field of adhesives and the preparation thereof. Background technique [0002] With the improvement of people's living standards and the continuous and stable development of construction, decoration, packaging and other industries, the output of wood-based panels in my country has grown rapidly. my country's total wood-based panel output, plywood output, furniture output, and wooden floor output have ranked first in the world for many years. In 2014, the total output of wood-based panels in the country was 273.7179 million cubic meters, an increase of 7.09% over 2013. Among the total wood-based panel production, plywood was 149.7003 million cubic meters, an increase of 9.07% over 2013, accounting for 54.69% of the t...
