Abstract

The present invention relates to a hemp-plastic composite material board and its preparation method, which relate to a composite material, an environmentally friendly material and its preparation method, and are suitable for making shelf boards, door inner boards, etc. of transportation vehicles such as automobiles and airplanes. Decorative panels, fences, railings, etc. in the construction field, pallets, shelves, etc. in the packaging field. The hemp-plastic composite material board is composed of two layers of hemp fiber modified plastic layer and hemp fiber cloth reinforced plastic layer, and a hemp fiber cloth reinforced plastic layer is molded between the two layers of hemp fiber modified plastic layer; the hemp fiber modified plastic layer is composed of Modified plastic particles, hemp fibers and interfacial compatibilizer are mixed and calendered; the reinforced plastic layer of hemp fiber cloth is formed by molding plastic particles and several layers of hemp fiber cloth treated with silane coupling agent.

Description

technical field [0001] The invention relates to a linen-plastic composite material plate and a preparation method thereof, which relate to a composite material, an environment-friendly material and a preparation method thereof. It is suitable for the production of shelf panels, door inner panels, etc. in the transportation field such as automobiles and airplanes, decorative panels, fences, railings, etc. in the construction field, and pallets, shelves, etc. in the packaging field. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, the demand for environmentally friendly, degradable and recyclable materials has become more and more vigorous, and the application fields have become wider and wider. Glass fiber reinforced plastic composite (commonly known as glass fiber reinforced plastic, GRP) products can be widely used due to the advantages of light weight and high specific strength, but at the same time ther...
