Abstract

The invention discloses a single component low-temperature polyurethane foaming adhesive which is characterized by comprising the following components in parts by weight: 150-200 parts of polypropylene glycol adipate or polybutylene adipate, 5-10 parts of trimethylolpropane, 10-30 parts of polyester 330N, 0.1-0.3 part of a catalyst, 80-150 parts of a black material and 200-340 parts of a solvent. The single component low-temperature polyurethane foaming adhesive disclosed by the invention is relatively long in surface dry time, relatively low in curing temperature and relatively short in real-dry time, so that the application range of the foaming adhesive is widened, the resource is saved, and the working efficiency of an operator is improved; the single component low-temperature polyurethane foaming adhesive disclosed by the invention is simple in preparation method and convenient to operate, so that the production cost of the single component low-temperature polyurethane foaming adhesive is lowered, and the popularization and the application are facilitated.

Description

technical field [0001] The invention relates to a foaming glue, in particular to a single-component low-temperature polyurethane foaming glue and a preparation method thereof. Background technique [0002] In the production and assembly process of decoration materials, it is generally used to apply foam glue to the gaps and holes of decoration material parts, and use the foaming characteristics and bonding characteristics of foam glue to fill, seal and bond them. . Commonly used styrofoams include silicone styrofoam, polysulfide styrofoam, and polyurethane styrofoam. Among them, styrofoam uses trace moisture in the air as a crosslinking accelerator, and cures to an elastic state at room temperature. The advantages of strong adhesion, good elasticity, insulation, high temperature resistance and cold resistance, high adhesion to general building decoration materials, and low price, so polyurethane foam has been widely used. At present, the quality of polyurethane foam on the...
