Abstract

The invention discloses a preparation method of a composite adhesive for an automotive interior material and belongs to the technical field of adhesives. The method comprises the steps as follows: mixing rice husk fiber, biogas slurry, sucrose and water for fermentation, and performing filtration, freezing, ball-milling, drying and carbonization to obtain modified fiber; placing polyether polyol in a reactor, performing heating, vacuum dehydration and cooling, then, adding isocyanate and an accelerator, performing a constant-temperature stirring reaction, next, adding trichloromethane, benzoylchloride, phospholipid, organic acid, plant essential oil, grease and mica powder, and performing stirring, mixing and discharging to obtain the composite adhesive for the automotive interior material. The composite adhesive for the automotive interior material has excellent bonding performance.

Description

technical field [0001] The invention discloses a preparation method of a composite adhesive for automotive interior materials, belonging to the technical field of adhesives. Background technique [0002] Polyurethane adhesives are adhesives that contain urethane groups or isocyanate groups in their molecular chains. In 1940, polyurethane adhesives were first developed for the bonding of metal and butadiene rubber. After the 1950s, two-component polyurethane adhesives began to be widely used, and gradually formed polyisocyanate solvent adhesives, two-component polyurethane adhesives, etc. Grease adhesives, one-component polyurethane adhesives, water-based polyurethane adhesives, hot-melt polyurethane adhesives, polyurethane sealants and other types, and began to be used in the automotive industry after the 1960s. [0003] There are many types of adhesives used in the automotive industry, which are divided into body adhesives, interior trim adhesives, brake pad adhesives, win...
