Low-smoke halogen-free flame-retardant automobile foot mat material and preparation method thereof

Abstract

The invention discloses a low-smoke halogen-free flame-retardant automobile foot mat material and a preparation method thereof. The composition is prepared from the following raw materials in parts byweight: 20-40 parts of starch and 20-40 parts of water. 100 parts by weight of a polyolefin elastomer; 5 to 25 parts by weight of polypropylene powder; 1 to 3 parts by weight of polypropylene graftedmaleic anhydride; 50 to 150 parts by weight of a flame retardant; the composition comprises the following components in parts by weight: 3-15 parts of a flame-retardant synergist I, 5-30 parts of a flame-retardant synergist II, 2-20 parts of a wear-resistant agent, 1.5-3 parts of simethicone, 0.5-2 parts of a light stabilizer, 0.5-2 parts of an ultraviolet absorbent and 0.1-1 part of an antioxidant. The automobile foot mat material prepared by the invention has the characteristics of low smoke, no halogen, flame retardance, softness, wear resistance, aging resistance, easiness in coloring andthe like.

Description

technical field [0001] The invention relates to a low-smoke, halogen-free, flame-retardant composite material and a preparation method thereof, in particular to a low-smoke, halogen-free, flame-retardant composite material for automobile floor mats and a preparation method thereof. Background technique [0002] With the vigorous development of the automobile industry and the increasingly stringent industry regulations, the requirements for automotive interiors and materials are getting higher and higher. As one of the most widely used automotive interiors, car floor mats are mostly made of traditional PVC materials. Since PVC material contains halogen, once burned in a closed space such as a car, it will not only release a large amount of smoke, but also produce highly toxic hydrogen halide gas, which is extremely harmful to people in a fire, and its application is greatly challenged. Some researchers have prepared automobile floor mat materials by using chlorine-containing...

Problems solved by technology

Some researchers have prepared car floor mat materials by using chlorine-containing flame retardant TCPP to modify thermoplastic polyurethane (TPU), but the problem of non-halogenation of materials has not been solved.

There are also researchers who use expanded graphite to modify TPE or TPR materials to prepare flame-retardant car floor mats. However, due to the black nature of graphite, the prepared floor mat materials are not easy to color, and the improvement of flame retardancy is also very limited.
