Problems solved by technology

[0002] Car interior mainly refers to the automotive products used in the interior modification of the car. The car interior is an important part of the car body, such as the rubber pad on the sub-dashboard of the car. The rubber pad on the sub-dashboard of the existing car is generally It is made of soft and hard glue and then assembled, but because it is assembled, there is a gap between the edges during the assembly process, which will easily cause dust to enter the edge, making it inconvenient to clean later, and because of the gap, in summer In the case of high temperature, there will be a larger gap between the two-color rubber, resulting in uneven surface of the joint, the soft rubber slightly protruding from the hard rubber, or the hard rubber slightly protruding from the soft rubber, which will affect the quality of the product and cause the two to separate. Afterwards, there will be unsightly problems, so it needs to be improved. In addition, the current rubber pads have poor high temperature resistance and poor flame retardancy, so they need to be improved.

Abstract

The invention discloses a double-color rubber mat at the front end of an automobile auxiliary instrument board and a preparation method of the double-color rubber mat. The double-color rubber mat comprises a black rubber layer of a square structure and a red rubber layer located in the center of the black rubber layer. The black rubber layer and the red rubber layer are formed by integral injection molding. The black rubber layer is prepared from the following raw materials in parts by weight: 40-50 parts of TPS thermoplastic elastomer, 10-15 parts of PP, 5-8 parts of paraffin-based filling oil, 5-12 parts of diatomite, 3-5 parts of an impact modifier, 5-10 parts of a binder, 12-15 parts of a phosphorus / nitrogen / silicon ternary composite flame retardant, 1-8 parts of a flame retardant synergist and melanin. The double-color rubber mat has the advantage that the flame retardance is improved.
