Problems solved by technology

[0002] With the improvement of living standards, the use of automotive products has gradually increased, especially in the aspect of automotive interior parts. At this stage, people's use of cars is not only for transportation, but has entered the stage of enjoyment. For automobiles The comfort level during use, especially in the heat insulation part of the car, requires damping materials for heat insulation, but the heat insulation materials used in the past basically absorb and conduct heat through the chemical properties of the damping materials to achieve heat insulation effects. However, the use of this kind of heat insulation material consumes a lot, the service life is not long, and the replacement cost is increased.

Abstract

The invention aims to provide a technological method for preparing a nano fireproof and heat-insulation material for a new energy bus. The technological method for preparing the nano fireproof and heat-insulation material comprises the following steps: (1) preparing the fireproof and heat-insulation material from the following components in parts by weight: 8-12 parts of diatomite, 12-15 parts ofsepiolite fabric, 20-25 parts of silicon dioxide, 10-15 parts of glass fibers, 5-8 parts of titanium powder metal and 3-5 parts of a bonding agent; (2) mixing the raw materials in step (1) in proportion, heating the raw materials and putting the raw materials into a stirrer to uniformly stir; and (3) performing extrusion molding on a jelly mixture in the step (2) through an extruder mould, performing nano-scale foaming treatment during extrusion molding, and performing natural air air-drying and cooling at a shade place. Nano-scale gaps are increased in the heat-insulation material, so that heat conduction speed can be effectively reduced, and the heat insulation effect is achieved.
