Abstract

The invention discloses an environment-friendly adhesive for an artificial board and a preparation method of the environment-friendly adhesive. The adhesive comprises the following components: water-soluble sodium silicate, sodium phosphate, nano silicon dioxide, spinel particles, glass fibers, tourmaline powder, magnesium oxide, zinc oxide, octyl phenol polyethylene ether, guanylurea phosphate, diammonium hydrogen phosphate, boric acid, an inorganic antibacterial agent and deionized water. The environment-friendly adhesive disclosed by the invention has the advantages that (1) aldehyde materials are not contained in raw materials, and free formaldehyde and any other harmful gases cannot be generated, so that the adhesive has the performance characteristics of environmental protection and safety; (2) the adhesive has high adhesive performance and internal bonding strength, is high in self-strength after molding, and can be used for improving the whole strength of the artificial board; (3) the adhesive has excellent properties such as flame resistance, bacterium inhibition, air purification and the like, the comprehensive performance and use safety of the artificial board, particularly the adhered artificial board, can be effectively improved, and the service life can be prolonged; and (4) the adhesive is simple in preparation process, strong in operability, good in quality stability and easy in sizing.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an environment-friendly adhesive for wood-based panels and a preparation method thereof. Background technique [0002] There is a shortage of wood resources in our country. The wood-based panels produced by using fast-growing wood, branch wood and crop straw can replace wood and be used in furniture manufacturing, indoor and outdoor decoration and other fields. The development of the wood-based panel industry is of great significance to the protection of my country's forest resources. In the preparation process of the above-mentioned wood-based panels, the adhesive plays a pivotal role. The amount of adhesive used has become an important symbol to measure the technical level of a country or region's wood industry. But at present, the adhesives used in my country's wood-based panels have the following disadvantages: 1. Mainly use aldehyde organic adhesive resins, such as urea-formaldehyd...
