Problems solved by technology

[0004] The crude protein content of high-temperature peanut meal is close to that of soybean meal, as high as 48%. However, the protein structure of high-temperature peanut meal is different from that of soybean meal, cottonseed meal and other plant proteins, so other protein-based glue-making processes cannot be applied to the preparation of high-temperature peanut meal adhesives.
However, the existing high-temperature peanut meal adhesive (ZL201510324194.5) has poor water resistance and low bonding strength, and cannot meet the needs of the national Class I wood-based panel industry.

Abstract

The invention provides a heat treated peanut meal-based formaldehyde-free adhesive. The adhesive is prepared from the following raw materials, in parts by weight: 150-220 parts of water, 50-70 parts of heat treated peanut meal, 1.6-2.2 parts of lauryl sodium sulfate, 1-1.6 parts of nano silicon dioxide, and 45-65 parts of PAE. The adhesive provided by the invention has no formaldehyde, is safe and environmentally friendly, and has high bonding strength and strong water resistance, and the bonding strength of a poplar plywood prepared from the adhesive can meet requirements of a national class I ordinary plywood in China.

Description

technical field [0001] The invention relates to the technical field of adhesives. More specifically, the present invention relates to a high-temperature peanut meal-based formaldehyde-free adhesive and its preparation method and application. Background technique [0002] my country is a big country in the production and consumption of wood-based panels and wood adhesives. At present, most of the commercially available adhesives are "trialdehyde" adhesives, that is, melamine-formaldehyde adhesives, phenolic resin adhesives and urea-formaldehyde resins. The production of wood-based panels relies on petroleum resources, and pollutes the environment and releases harmful substances such as formaldehyde, which restricts the development of the wood-based panel industry. [0003] Due to the advantages of no formaldehyde release, green environmental protection and renewable, vegetable protein adhesives are mainly used to replace the currently widely used three-aldehyde adhesives, and...
