A light-weight flame-retardant composite panel for bus roof skirt

Abstract

The invention provides a lightweight flame retardant composite plate for a bus roof skirt plate. The composite plate comprises a base material, a bonding layer and a surface layer, wherein the base material and the surface layer are fixedly connected into a whole body through the bonding layer according to the forming process of the bus roof skirt plate, and the overall thickness is 3.5 mm, the surface density is 2.0 kg / m<2>; the base material is glass fiber reinforced thermoplastic plastic, the bonding layer is a polyurethane adhesive, and the surface layer is a fireproof plate. The base material surface of the lightweight flame retardant composite plate is low in density, the surface material used is good in flame-retardant performance and does not produce rot and mildew; the lightweight flame retardant composite plate has obvious advantages that the plate is light in weight, high in level of flame retardance and fire control and low in odor, the content of volatile organic matter (VOC) meets national standards and the like. The problems of large surface density, VOC out of the limit in the existing bus roof skirt plate products are effectively solved, at the same time the abnormal noise problems produced in the use of aluminum-plastic plates in the prior art and the rot, mildew, delamination problems produced in the use of high density plate cannot appear.

Description

technical field [0001] The invention relates to the technical field of bus roof skirts, in particular to a lightweight flame-retardant composite board used for bus roof skirts. Background technique [0002] Existing bus roof skirts mostly use (perforated) aluminum-plastic panels and high-density panels with a thickness of 3mm. The surface density of the above two panels is high, as high as 3.0kg / ㎡, which does not meet the trend of lightweight bus development ; Simultaneously, the environmental protection performance of these two kinds of boards is poor, and the content of volatile organic compounds is high, and the harm to environment and people's health is caused to a certain degree. [0003] In general, (perforated) aluminum-plastic panels are mostly used in relatively high-end buses due to their unique metal texture. However, aluminum-plastic panels will produce abnormal noise problems when they are used; , The texture is average, and it is mostly used in low-end buses, ...
