Abstract

The invention provides a high temperature resistant hot melt adhesive which is made from an elastic body, synthesized high melting-point wax, synthetic resin, a plasticizer and an antioxidizer. The hot melt adhesive has high softening point, strong adhesive attraction and penetrability, and appropriate viscosity. The hot melt adhesive is used to splice a device; and the use method is simple and convenient, the device splicing is firm, and the high temperature resistant property and the anti-aging property are good. The product does not contain a poisonous solvent, thereby belonging to an environmental-friendly product.

Description

technical field [0001] The invention belongs to the industrial field, and relates to a high-temperature-resistant hot-melt adhesive used for bonding automobile interior parts and a preparation method thereof. Background technique [0002] In automobile manufacturing, although many parts are connected by fasteners. However, various glues are used to realize the connection and sealing of non-metallic parts, so the performance of the glue has a great relationship with the quality of the car parts and the whole car. The thermoplastic hot melt adhesives widely used in industrial production are mainly made of EVA and polyethylene. Such as a kind of hot-melt adhesive composition disclosed in Chinese patent CN1759156A, and a kind of hot-melt adhesive for packaging disclosed in CN1351104A. The adhesives prepared by these patented technologies have relatively large melt viscosity, poor toughness at low temperature, poor low temperature performance, inconvenient use, and limited appl...
