Abstract

The invention discloses polyurethane rigid foam for automobile seat processing, which is characterized in that manufacturing raw materials of the polyurethane rigid foam for automobile seat processingcomprise a material A and a material B, the mass part ratio of the material A to the material B is 100: 41-42, and the material B is an isocyanate raw material. The manufacturing raw materials for producing the polyurethane rigid foam for automobile seat processing are simple and easy to obtain, and the polyurethane rigid foam for automobile seat processing can be produced on a large scale. By adding a certain amount of a delay catalyst and a later catalyst, the reaction speed of the material A and the material B can be delayed to a certain extent, the material A and the material B can be fully filled in a mold, and bubbles are prevented from being generated. The small-range fracture situation can be treated in time in the point repairing process, and the material A and the material B canbe uniformly fluffed up in the fluffing process by spraying a release agent, so that the fracture situation is prevented from occurring.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to a rigid polyurethane foam for car seat processing and a manufacturing method thereof. Background technique [0002] According to the shape, car seats can be divided into separate seats and bench seats; according to their functions, they can be divided into fixed, detachable and adjustable; According to the performance of the seat, it has been developed from the earliest fixed seat to the multi-functional power-adjustable seat, including air cushion seat, electric seat, stereo seat, mental recovery seat, and electronically adjustable seat. . According to the material, it can be divided into leather seats and velvet seats. There are also some seats for special use, such as child seats and racing seats. [0003] Certain fillers are needed in the manufacturing process of car seats, and most of this kind of fillers are filled with polyurethane rigid foam. Placing it in a mold fo...
