Preparation method for novel vehicle seat

Abstract

The invention provides a preparation method for a novel vehicle seat. The preparation method is characterized by adopting an aluminium alloy seat frame and a polyurethane foam seat cushion which are developed by the applicant self. Particularly, the aluminium alloy comprises the following components in percentage by weight (wt.%): 4.0 to 4.5 % of Mg, 0.6 to 0.8 % of Si, 0.6 to 1.0% of Cu, 0.05 to 0.1% of Mn, 0.05 to 0.1% of Cr, 0.05 to 0.1% of Zr, 0.05 to 0.1% of Zn, 0.1 to 0.2% of Sn and 0.01 to 0.05% of Sr. The polyurethane foam is a soft polyurethane foam material obtained through the reaction of a polyhydric alcohol composition and polyisocyanate under the condition that a catalyst, a foaming agent, a foam stabilizer and a fire retardant exist. The aluminium alloy is machined into the seat frame, the polyurethane foam material is used as an elastic layer of the seat cushion after incision, the surface of the elastic layer is coated with a non-woven fabric layer and a leather layer coat, all layers are bonded into the seat cushion through a binding agent, and the seat frame and the seat cushion are assembled to form the vehicle seat.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to provide an auto seat with light weight and superior performance and a preparation method thereof. Background technique [0002] With the continuous development of the automobile industry and people's continuous pursuit of improving the quality of automobiles, the requirements for auto parts materials are also increasing. As for car seats, for the sake of vehicle driving economy and the safety and comfort of drivers and passengers, for the polymer elastic materials used as seat cushions and the alloy materials used as seat skeletons and frames, Various demands have been put forward. [0003] It is well known that flexible polyurethane foams are obtained by reacting polyisocyanates with high molecular weight isocyanate-reactive compounds in the presence of blowing agents. The flexible polyurethane foam material is widely used in the production and preparation of automobile sea...

AI Technical Summary

Problems solved by technology

The 5000 series (Al-Mg) aluminum alloy has very excellent formability, but it is easy to produce tensile strain marks in the process of pressing and forming, which will affect the aesthetics of the component surface, and at the same time, there will be obvious softening of the baking paint during the baking process , so that the strength is difficult to meet the requirements of use

Although the 6000 series (Al-Mg-Si) magnesium alloy hardly appears tensile strain grains during the pressing process, and can improve the yield strength through a flexible paint heat treatment process, however, compared with the 5000 series (Al-Mg ) aluminum alloy, its formability is much inferior
