Reusable load-carrying vehicle mixed fiver floor heat-insulation mattress forming technique

Abstract

The invention relates to a forming process for a recyclable insulating mat of a mixed fiber floor of a load-carrying vehicle. The forming process is characterized by comprising: mixing 35 to 40 weight portions of polyester fibers, 25 to 30 weight portions of acrylic fibers, 25 to 30 weight portions of polyamide fibers and 10 to 15 weight portions of polypropylene fibers; and spreading mixed fiber sheets, spreading ethylene-vinylacetate copolymer (EVA), spreading aluminium foils, heating by an oven, mould cold pressing, trimming and obtaining the finished product, wherein the temperature of the oven is kept at 160+ / -5DEC C for 20 minutes and the forming pressure is 4kg / m<2>. The process saves two procedures of spreading non-woven fabrics and glue spreading, avoids mould heating, forms directly at normal temperature, and reduces material cost and manufacturing cost.

Description

Technical field: [0001] The invention relates to a recyclable forming process for a heat insulation pad of a mixed fiber floor of a truck, which is used for the heat insulation pad of a mixed fiber floor of a truck. Background technique: [0002] At present, the floor heat insulation pads of medium and heavy trucks produced in China are all made of glass fiber. After this kind of fiber material is cured by thermoforming, the fiber becomes brittle and easy to break, and the broken fiber will fall seriously during the production and assembly of products, which will affect the surrounding environment and human health; moreover, using glass fiber The finished product is difficult to recycle after it is scrapped, causing pollution to the environment. The molding process of the traditional glass fiber floor heat insulation mat is as follows: laying non-woven fabric → laying glass fiber (impregnated) → laying EVA (ethylene-vinyl acetate copolymer) → laying aluminum foil → mold hot...
