Problems solved by technology

But because the polyurethane used in this invention is semi-rigid foam polyurethane, the hardness is not enough, so it needs glass fiber reinforced plastics support. Because of this, its production method is very complicated, which increases the production cost of the automobile instrument panel virtually and reduces the production cost. efficiency

Abstract

The invention discloses a manufacturing technology of an automobile instrument desk. The manufacturing technology comprises the following steps: (1) preparing raw materials for manufacturing the automobile instrument desk: infiltrating sufficient amount of polyether polyol, amine catalyst, silicone oil, hole opening agent, foaming agent and chain extender into a raw material barrel of group A of a foaming machine, and infiltrating sufficient amount of coarse MDI (diphenyl methane diisocyanate) into a raw material barrel of group B of the foaming machine; (2) manufacturing the automobile instrument desk: 1) manufacturing a shell of the automobile instrument desk; laying leather at the bottom of the mould, using the foaming machine to infiltrate the raw materials in the raw material barrels of group A and group B into the mould according to the weight ratio, removing the raw material from the mould after three to five minutes of reaction of the raw material in the mould, at this moment, the leather is attached on a polyurethane foam sheet, performing trimming cut on the polyurethane foam sheet to obtain the shell of the automobile instrument desk; 2) assembling: installing a required instrument on the shell of the automobile instrument desk so as to complete the manufacturing of the automobile instrument desk. The manufacturing technology is simple in process, low in production cost and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of automobile interior decoration, and in particular relates to a manufacturing process of an automobile instrument panel. Background technique [0002] With the rapid development of the automobile industry and the increasing demand for luxury passenger cars, the general appearance of the domestic traditional craft ABS (alloy plate) + polyurethane foam (soft foam) + FRP (glass reinforced plastic lining) instrument panel can no longer meet the needs of luxury passenger cars. For decoration, the imported PVC imitation leather + polyurethane and fiber mixed foam (hard foam) luxury bus instrument panel is expensive. The research and development of domestic luxury bus instrument panel has been mentioned in the current domestic automobile development agenda. [0003] The invention of application number 200910114402.3 discloses a glass fiber reinforced plastic blister instrument panel and its manufacturing process,...
