Problems solved by technology

However, high-strength double-sided tape needs to be pasted manually, which is inefficient and has poor final strength, which cannot meet the production rhythm of an automated assembly line.
[0004] In order to improve the initial adhesion of the hot melt adhesive, add a tackifying resin to accelerate the coagulation of the hot melt adhesive when the hot melt adhesive is cooled, but it will lead to a very brittle system, poor toughness, and poor heat resistance.

Abstract

The invention provides a special hot melt adhesive for a composite floor mat, which at least comprises the following preparation raw materials in parts by weight: 20-70 parts of polyester polyol, 0.1-5 part of modifier, 0.1-5 part of tackifying resin, 0.1-0.5 part of catalyst, 0.1-2 part of silane coupling agent and 0.05-1 part of antioxidant.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a special hot melt adhesive for composite floor mats and a preparation method thereof. Background technique [0002] Moisture-curing polyurethane hot-melt adhesive, referred to as PUR, is solid at room temperature and does not contain solvent plasticizers. When in use, it is heated to make it liquid and immediately applied to the surface of the adherend, and then attached to another adherend. When the adhesive is cooled and solidified, the isocyanate reacts with the moisture on the surface of the adherend or the moisture in the air to extend the chain into a polymer compound, thereby producing an adhesive force. Compared with other hot-melt adhesives, reactive polyurethane hot-melt adhesives (PU-RHMAs) have the following advantages: low operating temperature, high thermal stability (moisture cross-linking and curing), and good adhesion on different substrates. Force (e.g. wood...
