Automotive trim flame-resistant material and preparing method thereof

Abstract

The invention discloses an automotive trim flame-resistant material and a preparing method thereof. The material comprises, by weight, 50-80 parts of polypropylene resin, 20-60 parts of anilmomethyl triethoxy silane, 10-40 parts of glass fiber reinforced polyethylene terephthalate, 20-30 parts of N-ethyl-p-toluenesulfonamide, 40-50 parts of barium sulfate, 40-50 parts of polyvinyl alcohol, 10-30 parts of dimethyl terephthalate, 20-60 parts of paraformaldehyde, 40-50 parts of arsenic trioxide, 2-8 parts of potassium oxide, 10-20 parts of dicyanodiamine, and 20-40 parts of adipic acid dihydrazide. According to the preparing method, the polypropylene resin, the anilmomethyl triethoxy silane, the glass fiber reinforced polyethylene terephthalate, the N-ethyl-p-toluenesulfonamide, the barium sulfate, the polyvinyl alcohol, the paraformaldehyde, the arsenic trioxide, the potassium oxide, the dicyanodiamine and the adipic acid dihydrazide are evenly mixed through a high-speed mixing machine for plasticizing fusion, dimethyl terephthalate injection is conducted at the same time, and the constituents are extruded after being mixed. The flame resistance of the automotive trim flame-resistant material is high.

Description

Technical field [0001] The invention involves a car interior flame retardant material and its preparation method. Background technique [0002] There are many types of car interior materials. They can be divided into three categories according to different raw materials. One is cellulose, one is plastic foam, and the other is natural rubber and synthetic rubber.In the internal design of the car, some flammable substances have a lot of contacts with the human body, such as seats, car carpets, airbags, etc. When the interior materials of these parts are on fire, they directly contact the human body, causing serious damage to the human body.Some parts of the car, such as battery partitions, are closer to the engine of the car, and it is easy to cause fire houses when the car engine fails, bringing losses to the entire car. [0003] CN103358602A opens a manufacturing method of a glue -back flame retardant material, including flame retardant fabrics, heat -resistant tape and isolati...

Problems solved by technology

In the interior design of automobiles, some flammable substances have many parts in contact with the human body, such as seats, car carpets, airbags, etc. When the interior materials in these parts are on fire, they will directly contact the human body and cause serious harm to the human body

Some parts of the car, such as the battery separator, are relatively close to the engine of the car. When the car engine fails, it is easy to cause a fire and bring losses to the entire car.
