Abstract

The invention discloses a light bastose and flame-retardant polypropylene fiber composite board which comprises 25-75wt% of bastose and 25-75wt% of flame-retardant polypropylene fibers. A method for manufacturing the light bastose and flame-retardant polypropylene fiber composite board includes performing flame-retardant treatment for the bastose; manufacturing the flame-retardant polypropylene fibers and the bastose which is subjected to the flame-retardant treatment into a composite felt; and performing baking and roll forming for the composite felt to obtain the light bastose and flame-retardant polypropylene fiber composite board. The light bastose and flame-retardant polypropylene fiber composite board used as an interior trim part of an automobile is environment-friendly and safe, and is excellent in flame-retardant performance owing to the flame-retardant polypropylene fibers and the flame-retardant treatment for the bastose, and potential safety hazards caused during production and service are prevented; mixed fibers are laid down in a crossed manner and the felt is formed by means of needling to form the board, raw materials are dispersed uniformly, degrees of adhesion of boundaries of the bastose and the polypropylene fibers are improved, and the board is excellent in comprehensive mechanical property; and the product is easy to form and simple in processing technology, the production efficiency can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a hemp fiber / flame-retardant polypropylene fiber lightweight composite board and a preparation method thereof. Background technique [0002] Environmental degradation, lack of resources and energy crisis have made mankind realize the importance and urgency of protecting the environment and effectively utilizing resources to achieve sustainable social and economic development. People have paid more and more attention to the use of renewable biological resources to manufacture new materials. In recent years, the use of natural plant fibers, which are the most abundant resources in nature, to replace the widely used synthetic reinforcing fibers such as glass fibers, and to develop composite materials with excellent performance and low cost has attracted great attention. [0003] Natural fibers show good application prospects due to their excellent characteristics...
