Problems solved by technology

Polyurethane adhesives were first industrialized in Germany in the 1940s, mainly including polyisocyanate solvent adhesives, thermoplastic polyurethane solvent adhesives, reactive single- and two-component solvent adhesives, solvent-free, water-dispersed, hot-melt polyurethane adhesives, etc. ; There are many types of synthetic raw materials and additives. Starting from molecular design, a series of adhesives with a wide range of performance can be synthesized and formulated, which can meet the requirements of different substrate bonding and use conditions. In the prior art, the traditional flame retardant Most of the agents are organophosphorus or halogen-containing flame retardants, but the content of free formaldehyde in the finished furniture or the content of halogen elements in the flame retardant is high, which is harmful to the human body, not environmentally friendly, and it is difficult to treat and discharge pollutants

Abstract

The invention discloses a one-component polyurethane adhesive for furniture and a preparation method of the one-component polyurethane adhesive. The preparation method comprises the following steps ofadding a function system in a modification system, adding 4,4-diphenylmethane and maleic anhydride under stirring at 60 DEG C, performing stirring for 35mins, then adding a foundational system, performing stirring for 85mins at the temperature of 110 DEG C, adding ethanol while performing natural cooling to obtain a system with the solid content being 65-70 percent, i.e., the one-component polyurethane adhesive for the furniture. The obtain product can be used in the furniture industry, has excellent peeling strength, fairly excellent flame retardancy and toughness and particularly good antibacterial property.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a one-component polyurethane adhesive for furniture and a preparation method thereof. Background technique [0002] With the gradual enhancement of people's awareness of environmental protection and the improvement of national environmental protection laws and regulations, the development of non-toxic, non-polluting, green and environmentally friendly wood adhesives has become an inevitable trend in the development of the industry. Polyurethane adhesives were first industrialized in Germany in the 1940s, mainly including polyisocyanate solvent adhesives, thermoplastic polyurethane solvent adhesives, reactive single- and two-component solvent adhesives, solvent-free, water-dispersed, hot-melt polyurethane adhesives, etc. ; There are many types of synthetic raw materials and additives.
