Problems solved by technology

Similarly, its preparation process will produce a lot of solid dust, not a completely environmentally friendly product
[0005] In addition, other reported patents on hot-melt adhesives and hot-melt adhesive films for automotive interior parts, such as Chinese patents CN103571423B and CN103571386, all need to be pre-mixed with a kneader, and the production process is cumbersome and the efficiency is low.
[0006] In summary, there is currently no environmentally friendly hot-melt adhesive film that is both antibacterial and flame-retardant, and has a simple processing technology for bonding automotive interior parts.

Abstract

The invention discloses an environmentally friendly hot melt adhesive membrane for automotive interior products, a preparation method and application. The environmentally friendly hot melt adhesive membrane for the automotive interior products comprises the following components in parts by mass: 100 parts of an elastic component, 0.1-50 parts of a non-elastic component and 0.1-20 parts of composite filler. The melt index of the elastic component is 0.9-30 g / 10 min (190 DEG C, 2.16 kg), the melt index of the non-elastic component is 0.2-10 g / 10 min (190 DEG C, 2.16 kg), and the melt index of the elastic component is greater than that of the non-elastic component. The composite filler comprises bamboo charcoal fibers and flame-retardant filler. The environmentally friendly hot melt adhesive membrane is used for adhesion of the automotive interior products, does not contain any organic solvents, does not produce toxic or harmful gas, and has antibacterial property and flame retardancy. Compared with a common antibacterial or flame-retardant product, the environmentally friendly hot melt adhesive membrane for the automotive interior products is simple and convenient to process.

Description

technical field [0001] The invention belongs to the technical field of polymer adhesives, and relates to a hot-melt adhesive film for automotive interior parts and its application, in particular to an environmentally friendly hot-melt adhesive film for automotive interior parts with antibacterial properties and flame retardancy and its preparation method. Background technique [0002] The global automobile market is booming. According to the data released by Jato Dynamics, in 2016, the global automobile sales in 52 markets reached 84.24 million, a year-on-year increase of 5.6%. The Chinese market achieved 23,685,048 new car sales, a year-on-year increase of 17%. With the rapid development of the automobile industry, the demand for adhesives for automotive interior parts is also increasing year by year. Hot-melt adhesive film, because of its ease of sizing, has greater development prospects than traditional adhesives. Nevertheless, the hot-melt adhesive films reported in ex...
