Abstract

The invention discloses environment-friendly backing glue for a car carpet. The environment-friendly backing glue adopts EVA as a main raw material and is prepared by uniformly mixing 10 to 50 parts by weight of EVA resin, 20 to 80 parts by weight of mineral powder and 0 to 10 parts by weight of additives by virtue of a high-speed mixing machine and granulating the mixture by virtue of a dual-screw extruder. Raw materials used in the environment-friendly EVA-base backing glue are environment-friendly, so that the environment-friendly EVA-base backing glue is pollution-free both to the environment and a user; the manufacturing process is simple; and a product is excellent in mechanics performance, good in processing performance, stable in quality, capable of meeting relevant requirements of the automobile industrial standard, suitable for industrialized mass production, widely applicable to the low, middle and top grade car carpets and good in application prospect.

Description

technical field [0001] The application belongs to the field of automobile carpet backing material and its manufacture, more specifically, the application relates to an environment-friendly EVA-based automobile carpet backing adhesive and a preparation method thereof. Background technique [0002] The backing of woven, needle-punched and tufted car carpets needs to be coated with adhesive to fix the fluff, stabilize the size, and make the carpet moisture-proof, cold-proof, heat-insulating, noise-reducing, vibration-reducing, and increase the firmness and deformation resistance of the carpet , has the characteristics of flame retardant, anti-fog, anti-mildew and odorless, which greatly improves the passenger comfort of mid-to-high-end cars. Car carpet backing material is an important part of the car carpet assembly, and the quality of the backing material directly affects the quality and performance of the carpet. At present, domestic automobile carpet backing materials use a...
