Foaming material and foaming board body

Abstract

The invention provides a foaming material, the foaming material is used for preparing a foaming plate body with a thin wall and low hardness, the foaming material comprises a component A and a component B. The component A comprises the following components in parts by weight: 80 to 90 parts of polyether triol; 4 to 6 parts of polyether glycol; 1.5 to 2.5 parts of a cross-linking agent; 0.1 to 0.5 part of silicone oil; 0.1 to 0.5 part of a foaming catalyst; 0.6 to 1.0 part of a gel catalyst; 2.0 to 3.0 parts of water; and the component B comprises MDI. Meanwhile, the invention also provides a foaming board body prepared by foaming the foaming material. According to the invention, the foaming material can form a thin-wall and low-hardness foaming layer, and the prepared foaming layer has good process stability and good soft touch feeling.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a foam material, and at the same time, the invention also relates to a foam board made of the foam material. Background technique [0002] With the increase in car quality and sales year by year, consumer demand is also increasing, and higher requirements are placed on the function and texture of car dashboards. In addition to the most basic function of covering, the instrument panel has increasingly become an important function of the instrument panel to provide comfortable operating space, provide a comfortable decoration environment, and provide suitable storage space. [0003] Instrument panel can be divided into hard plastic instrument panel and soft instrument panel according to comfort. According to the type of assembly process of the instrument panel body, the soft instrument panel is divided into slush-molded foam instrument panel, female molded ins...

Problems solved by technology

[0005]In view of the fact that the lightweight of automotive materials is one of the most important themes in the development of the automotive industry, the lightweight of the slush foamed instrument panel is mainly achieved by reducing the thickness of the foam layer , the foaming thickness of the traditional slush-molded instrument plate is between 7-9mm, and the thinner the foam layer, the worse the process stability and the lower the product qualification rate

Moreover, products made of traditional foam materials make the covered instrument panel feel hard, which affects the delicate feeling of the instrument panel
