Abstract

The invention relates to the technical field of manufacturing of fiber liner products, and especially relates to a manufacturing method of an expansion type heat insulation supporting liner. The method comprises the following steps: selecting aluminum silicate fibers, conducting purifying, adding water to prepare fiber slurry, homogenizing the slurry, adding vermiculite into the aluminum silicatefiber slurry by adopting a special vermiculite feeding device, homogenizing the formed slurry, conducting dispersing, conducting primarily filtering, pressing and shaping a filter cake by adopting a compression roller of a special liner forming box, carrying out vacuum filtration, then conducting sizing, and carrying out microwave drying to obtain the expansion type heat insulation supporting liner. Compared with a basic expansion type liner, the liner prepared through the method is more excellent in high- and low-temperature supporting force performance and high in anti-blowing-corrosion capacity; and the linear has more excellent performance in the aspects of heat insulation effect, gap sealing, blowing corrosion resistance and the like.

Description

technical field [0001] The invention relates to the technical field of fabricating fiber cushion products, in particular to a fabricating method of an inflatable heat-insulating support cushion. Background technique [0002] At present, China has become the world's largest automobile production and sales country, and the automobile industry has become one of the pillar industries; in the entire automobile industry chain, there are many supporting production and service companies. Moreover, as the national environmental protection regulations become more and more stringent, high technical requirements are put forward for automobile production as a whole; especially in terms of engine and exhaust treatment, more advanced technology, more economical and environmentally friendly materials, and more reasonable disposal are required Solution. However, at present, the overall domestic automobile manufacturing and parts manufacturing still lag behind the technology of foreign devel...
