Preparation method of biological fiber and plastic composite material with high insulating property

Abstract

The invention relates to the technical field of composite materials and discloses a preparation method of a biological fiber and plastic composite material with a high insulating property. The composite material is prepared from the following raw materials in percentage by weight: 50-60% of biological fiber powder, 25-34% of a plastic, 10-25% of insulating powder, 2-5% of a compatilizer, 1.2-2.5%of a lubricant, 1-2% of other auxiliary agents and 2-5% of non-polar filler, wherein the other auxiliary agents are a mixture of a mildew preventive and extinction powder in a weight ratio of 1: 1 andthe non-polar filler is a mixture of calcium powder and talc powder in a weight ratio of 1: 1. According to the preparation method of the biological fiber and plastic composite material with high insulating property, by adding the biological fibers and the plastic, the produced composite material is high in hardness and good in toughness, and meanwhile, the raw materials and equipment are cheap,the costs of the raw materials and cost are lowered, the production process is simple, and batch production is facilitated. A crusher crushes the biological fibers and the plastic into particles closein size, so that the biological fibers and the plastic are blended fully. The surface of a product can be treated according to the demand of a client, so that the product is diverse in appearance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a preparation method of biological fibers and plastic composite materials with high insulation performance. Background technique [0002] Composite materials are new materials that people use advanced material preparation technology to optimize the combination of material components with different properties. Composite materials must be man-made, designed and manufactured by people according to needs, and must be composed of two or more chemical materials. Or material components with different physical properties are combined in the designed form, proportion and distribution. There are obvious interfaces between the components. It has structural designability and can be designed for composite structures. Composite materials not only maintain The advantages of the performance of each component material, and the comprehensive performance that cannot be achieved by a sin...
